No book of tliis particular kind, showing iUnstrations of modern American marine engines, has ever Ijeen pubHshed in the United vStates. Many American readers are familiar with that excellent British work, " Maw's Marine Engines," b>' Wm. H. Maw, and if one goes to a technical book publisher for a copy of a publication uptjn marine engines, he will be offered one of the many English or Scotch works on that subject, as no American book can l)e found. The same raa>' be said of works npoii steamships and yachts. In the preparation of this book I have used se\-eral articles and cuts that have previoush' appeared in the leading marine and mechanical journals of the United States and Great Britain. In this connection I will thank in advance the editors and proprietors of the following papers ; Engmeei intr ^ The Engineer, London: The Engineer. Xew York; The Steamship, I^eith, vScotland ; Maritie Engineer, London; Ameriean Engineer, New York; .Atneriean MiuliinisI , New York ; /'),('<;', New York ; Seienlifie Anierie' of Rome, America, Empress of Japan, etc., but these additions to the work will doubtless be appreciated by shipbuilders and engineers. To make the book more intere.sting and complete, portraits of some of the designers and builders of the vessels and engines shown in these pages have been added. A few cuts of some well-known marine men are also inserted, G. FOSTER HOWELL, Brooklyn, .\. )'., January /, iSi)6. y2 1 LaFAVETTE AvENUE. TABLE OF CONTENTS.

The dimensions of the vessel are as follows : Length over all, 554.2 feet ; length between perpendiculars, 535.8 feet ; ex- treme beam, 63 feet ; gross tonnage, 11,629.21 tons; net ton- nage, 5,893.73 tons. The St. Louis and St. Paul are sister ships. Both were built by \Vm. Cramp & Sons. ENGINES OF THE AJIERICAN LINE STEAMER ST. LOUIS. The main engines are of the quadruple-expansion t>pe, with six cylinders working on four cranks, an arrangement de- signed by the Cramps. There are two high-pressure cylinders, and each of these is placed over one of the two low-pressure cylinders. The tandem cylinders are at the forward end, the arrangement being high-pressure and low-pre.ssure working on the first crank, the same working on the second crank, the second intermediate on the third crank, and the fir.st intermedi- ate on the fourth crank. The diameters of the respective C5"linders are : two high-pressure, 28'j inches ; first intermedi- ate, 55 inches ; .second intermediate, 77 inches ; two low-pres- sure, 77 inches. The stroke in each case is 5 feet. The cylin- ders are each .separate castings, and are supported on A-frames at back and front, the conden.ser and its pumps being separate and placed in the wings of the ship. The supporting frames are cast in two parts, each part having three sides only, with flanges to the outside for bolting together. The niside is thus entirely' open, so that the soundness of the casting is apparent. The cylinders are braced longitudinally by cast-iron girders of box section, which also extend between the forward and aft cylinder and the ship's bulkhead, so that there is little tendency to work. The.se bulkheads are .specially stiffened by girders 2 feet deep, built of plates and angle bars. Each high-pressure cylinder is carried 24 inches alaove the low-pressure cylinder on cast-iron frames on either .side, and this clearance enables a manhole to be provided on the top of the low-pressure cylinder to admit of examination, etc. The main stop valve is in the engine-room, on the same level as the high-pressure cylinders ; and the inlet to the high-pressure cylinder valves is controlled by a balanced piston throttle valve on the main pipe. The steam pipes, it may be said, are all of steel, lap-welded, with double-riveted flanges, and the largest is 20 inches in diameter. Piston valves of the Thom's balanced type are fitted throughout, and they are operated by the usual double-eccen- tric link motion, the bent rod being for the a.stern motion. There are two valves for the low-pres.sure cylinders. The spindle of the high-pressure cylinder valve is worked from the low-pressure valve crosshead through a bell-crank lever. The second intermediate and the two low-pressure cyl- inders only have jackets, and these drain into water taps which discharge into the hot-well tank. Outside all the cylinders are coated with asbestos, hair- felt, and covered with sheet steel. Cramp's metallic packing is used throughout. It is somewhat similiar to the United States packing, with cast-iron rings com- pres,sed by a spiral spring. The clearance in the cylinders is on the top of the pi,stons '4 inch, and below, 5 s inch. The piston- rods of the high-pressure cylinders are 6 inches in diameter, and in the other C5dinders8'j inches. The connecting-rod is fully twice the length of stroke, 1 1 feet 3 inches centers, and it is Sj4 inches in diameter at top, and 10 inches at bottom. The connecting-rod at top is not forged with the usual IT-end for the crosshead pins. The cro.sshead connection is built up. The top of the rod is squared to a T-piece, with a hole bored through the two heads. On the bottom of the crosshead itself, at either side, there is a forged projection, which is screwed and passed through the holes and bolted. In other words, the cro.sshead brasses have a steel T-piece with pin forged to the bottom which pas.ses through the holes on the top of the connecting-rod. Slipper guides for the crosshead are fitted to one side of the framing. There is a steel flange fitted on either side of the column face, and the slipper works inside it. Between the back of the crosshead and the other frame there is a small gangway to admit of inspection, and to economize weight a hoie is bored through the crosshead brasses, which also have the usual piece for adjustment. The crank shaft is 21 inches in diameter, the crank pins 22 inches, the bolts being 5 inches at the bottom of the thread. The cranks themselves are 16 inches broad, the length of pin being 3114 inches, and there is a 6-inch hole through the cranks and pins. The bearings are 26 inches long, and are of cast steel filled with Parson's metal. They are bolted down with 4 '2 -inch bolts, and in the bottom water is cir- culated. Here it may be stated that the bed-plate is of cast- iron box-.section , 3 feet 4 inches deep, and 4 feet 7 inches at the center, the center part, instead of being fiat, being dished to the extent of i foot. The ba.ses of the .standards are fitted to the dished part of the bed-plate as well as the flat portion, so as to tend to obviate the radial "working," which sets up torsional vibration and .strains. The thrust shaft is 21 inches in diameter, and solid, the diameter over thrust rings being 33 inches. There are 13 horse.shoe collars, each 2^2 inches thick, and the surface on the ahead side is 6,616 square inches. The length of the thrust shaft is 14 feet, and it is secured to the bed-plate of the engines. The horseshoe rings are adjustable bj' a horizontal screw with two nuts for each side, which greatl^^ facilitates the removal of any ring. The turning wheel is immediately aft of the thrust shaft. The engine has two cylinders, S inches in diameter by s inches stroke. The thru.st shaft, by the way, is placed in a recess, and over it, with entrance from an upper platform, is the dj'namo-room. The propeller or line shaft is 19 inches in diameter, also solid. It is fitted in lengths of 23 feet, with bearings 14 feet apart. These bearings are 2 feet long, and have cast-steel bobies, filled with Par.son's white metal. There is fitted to the after length of the shaft a portable coupling. It is in halves, and through each half there is a longitudinal feather 5 inches wide and 2 '4 inches deep. The ten bolts were put through the coupling when at a high temperature, the subsequent contrac- tion giving greater binding to obviate slip. This arrangement, which is not usual, is to facilitate the drawing of the shaft for repair. The feathers running longitudinally through each half of the coupling would not have prevented the shaft from backing out when the engine was .going astern, and to over- come this possibility, grooves i inch deep were turned in the shaft, forming collars, which engage in collars and grooves on the coupling. There is no outboard shaft, the framing and plating of the ship being bossed out in the same way as in most high-.speed twin-screw merchant steamers now. The stern shaft, which is 21 inches in diameter, is covered with a liner iij inches, working in lignum-vitse bearings, con.structed in the old style in .strips 3i.< inches broad and 1 inch deep, the division between the strips allowing water to circulate. ' The HOWKLL'vS STEAM VESSEI.S AND MARINE ENGINES. QuADRrpi.E-ExpANSroN EN4 inch thick, the dis- tance between the tube sheets being 7 feet. The tubes, bj' the way, are fitted with spiral retarders which have given good re- sults in causing the hot ga.ses to pass in a helical course through the tubes, and thus insure prolonged contact with the surface. The tube plates are 5g inch thick. The diameter of the com- bustion chamber stays at the smallest ba.se is i Yx inches for the outside row, and iS-k inches for the inside row; by 7 inches pitch. The total grate area is 1,144 square feet, and the total heating surface 40,320 square feet. There are six safety valves on the double-ended, and four on the single-ended boilers, all of 4 inches diameter. The installation of boilers is equally divided between two water-tight compartments. There are thus three double-ended and two single-ended boilers in each, and the installation is worked under Howden's system of forced draught, by which the air is heated before being passed into the furnace. The stokehold is open, and is specially well ventilated. It is divided longitudinall}' in the middle line b}' a thin plating or screen, which comes to within 6 feet of the heads of the stokers. The down air shaft is on the one side of this screen, and the other side is closed in at the top, excepting the in-take for the forced draught fans. Thus the current of air is brought as near the stoking floor as possible. There is bunker capacity for carrying 2,500 tons of coal, which will ju.st equal eight days' consump- tion. The Cunard Line Twin=Screw Steamer Campania. This splendid specimen of British naval architecture and marine engineering was constructed at the Fairfield Shipbuild- ing Works, Govan, Gla.sgow, and is a sister ship to the Lucania. These works were founded by the late John Elder. The Cam- pania has two sets of triple-expansion engines of 15,000 horse- power each. The dimensions of the hull are : Length over all, 622 feet ; between perpendiculars, 600 feet ; breadth, 65 feet ; tonnage, 12,950. The plates are of steel, 25 feet long, 6 feet wide and i inch thick. Steam is supplied from twelve main double-ended boilers, 18 feet in diameter and 17 feet long, each having eight corrugated furnaces, giving a total grate sur- face of 2,250 square feet. Each boiler weighs nearly 100 tons. The two funnels, it may be added, are from their lowest section 120 feet high, or about the height of the Eddystone lighthouse. They are each 21 feet in diameter. The boilers are in two bat- teries, separated by a coal bunker 65 feet in length. Additional coal bunkers are placed over and around the boilers to protect them from shot in case of war. Natural draught is used, ventilation being provided by means of immense ventilators mechanically driven. The boiler plates are iVz inches in thickness. The bulkhead that divides the two engine-rooms is the only longitudinal bulkhead in the ship. The engines receive steam at 165 pounds pressure and are triple-expansion, having five cylinders — two high-pressure, 37 inches in diameter ; one intermediate, 79 inches in diameter : and two low-pressure cylinders, 98 inches in diameter, with a stroke of piston in each case of 69 inches. These cylinders are arranged with one high-pressure cylinder over each low-pressure cylinder, working tandem on the same rod, and the inter- mediate cylinder between them. These v\ork three cranks, set at angles of 120° from each other, the crank shaft being 26 inches in diameter. On her trial trip, with 165 pounds pressure and 28 inches vacuum, at 84 revolutions per minute, the two engines indicated 31,050 hor.se- [jower, and de\'eloped an average speed of 23.18 knots. The engines are of a peculiar type, designed to reduce the space into which engines of great power ma)' be compre.ssed. If the old-fashioned plan of using three cylinders for triple-expansion had been followed, it was seen that the low-pressure cylinders in a case of 15,000 horse-power would have been greater in diameter than existing machinery could produce with accuracy, or than space could be provided for in the vessels it was proposed to drive. The plan adopted, therefore, was to divide both the high-pressure and the low-pressure cylinders into two, to place a small high- pressure cylinder on the top of a low-pressure, and to put the pistons in each case on the same piston-rod and work them tandem fashion. The intermediate cylinder stands alone in the middle of the series, and the piston-rods of each connect with one of the three cranks of the screw shaft. This arrange- ment got rid of another difficulty. Formerl}' there appeared Irom the top of the low-pressure cylinders a guide-rod, de.signed to prevent the large circumference of the piston in these large cylinders from wearing unevenly ; but, with steam pressure of over 100 pounds, this guide-rod was a constant source of difficulty. It is by this five-cylinder arrangement entirely superseded. The piston of the high-pressure cylinder acts as a guide-rod for the lower and larger diameter, and the steam is entirely boxed in. The piston, piston-rods and connecting- rods of these engines weigh about 120 tons; they have a .stroke of 69 inches, and at 8i revolutions — the normal speed of the engines — this enormous weight is moved at a di.stance of nearly 1,000 feet each minute. The crank shaft is 26 inches in diameter, and each of the three interchangeable parts weighs 27 tons and is some 27 inches in diameter. These, with the thrust shaft 14 feet long, make up a total of 110 tons for each crank shaft. The propeller shaft is 24 inches in diameter, and is fitted in lengths of 24 feet, each length having two bearings; and the thrust block is fitted with fourteen rings. The propeller, which is placed on the end of the shaft without any interior overhanging bracket, is three-bladed, and each blade weighs eight tons, or forty-eight tons in all. American Steamship Savannah. The first voyages of a .steamship across the Atlantic were made in 1819 by the Savannah, an American ves.sel carrj-- ing the American flag and manned by an American crew. It seems eminently proper to preserve an authentic record of the event connected therewith in our national archives, particularly since the original log-book of the.se voyages is in the collection of theU. S. National Museum. So far as is known, no reliable drawings of the Savannah are in existence. A lithograph, fault)' in many of the details of the hull, sails and rigging, has been the basis of all previous illustrations of this historic ves.sel. In view of this fact, a corrected drawing, based upon early descriptions of this vessel, together with such details of description as are extant, has been made by C. H. Hudson, 14 HOWFXI.'S STKAM VESSELS AND MARINE ENGINES. Thi-; Campania. The CrNAki) Twin-Scrhw Stkamer CA^rpANiA.

Commissioner of Fish and Fisheries, and Curator of the Section of Naval Architecture in the National Museum, Washington, D. C, whose familiarity with the history of naval architecture and the construction of sailing vessels, contemporary with the Savannah, has enabled him to correct many errors and supply the deficiency in the original lithograph. The following notes, explanatory of certain technicalities in the drawing, have been furnished by Captain Collins; The history of the Savannah shows that she was designed, origin- ally, for a sailing ship; that her construction was already well advanced when it was determined to make a steamship of her, and that she was rigged as a sailing vessel, steam apparently being considered chiefly auxiliary, to be used principally in calms or with light oi' head winds. The contemporaneous lithograph and all other illustrations of this famous vessel, represent her as a full-rigged ship, with, however, no sails loftier than topgallant sails, with her mainmast and foremast more widely separated than on ships designed for sail alone, and having a round stern. The sailing ships of that period were usually rigged very loftily, commonly carrying royals, while the almost universal type of stern was square. Never- theless, it is reasonable to suppose that those having charge of the rig and equipment of the Savaimah may have felt that light sails, which could be used only in moderate winds, would not be necessary on a ship having .steam as an auxiliary motive power, and that her .stern was round is by no means impos- sible. Therefore, not having any authority for changing tlie.se details, they have been represented as in the original lithograph; the relative positions of the masts, smokestack, and wheels are also retained. In all details of hull and rig, with the exception of those mentioned, the effort has been to produce a ship of the period when the Savannah was built, and special attention has been given to the details of sails and rigging, points in which all illustrations of this ship, previou.sly extant, were markedly erroneous and unsatisfactory. The ship is represented as close hauled on the starboard tack, in a fresh breeze, with her paddle- wheels in motion. She is rising on the slope of an Atlantic swell, leaning well over to the breeze, while the yeasty wave, curling away from her bow and sweeping in foam along her sides, indicates that .she is moving at a good speed. The fore- top-gallant sail has ju.st been clewed up and two seamen are seen climbing the rigging to furl the canvas, while in the distance another ship is in sight, running before the wind with square yards. The Savannah was a full-rigged ship of 350 tons burthen, and was built at Corlear's Hook, New York, by Francis Fickett and David Crocker, from designs of Wm. Scarborough, of Savannah, Ga. At fir.st .she was intended to be used as a .sailing packet between New York and Havre, France. The keel was laid in 1818, and the vessel was launched Augu.st 22 of the same year. While the Sa' annah stood upon the stocks she attracted the attention of Capt. Moses Rogers, who had been associated with Fulton and Stevens in commanding several of the early .steamboats. It was through his exertions that Scarbo- rough & Isaacs, a wealthy shipping firm in Savannah, were induced to purchase the vessel and fit her with engines wnth a view of giving to that cit>', which was then one of the most important American seaports, the credit of being the first to in- augurate a transatlantic steamship line. The Savannah was equipped with one inclined, direct-acting, low-pre.s.sure engine of 90 horse-power, the diameter of the cylinder being forty inches and the stroke 5 feet. Her engine was built by Stephen A^'ail at vSpeedwell Iron Works, near Morristown, N. J. The boilers were built at Elizabeth, N. J., by Daniel Dod or Dodge. The paddle-wheels consisted of eight radial arms, held in place by one flange, and were arranged to close together like a fan. They were furnished with a series of joints so that they could be detached from the .shaft and taken in on deck when storm or other circumstances require it. Her shaft had a peculiar joint at each end arranged for the purpose. The wheelhouse was made of canvas, stretched over an iron rim. It is unfortunate that no detailed drawing or accurate descrip- tion of the wheels or machinery is in existence. The vessel carried 75 tons of coal and 25 cords of wood. The total cost was about $50,000, including engines and all rigging. An account book containing a record of the original charges made against the Savannah for machinery, etc., by the propri- etors of the Speedwell Iron Works, is now in the possession of John Lidgerwood, of No. 26 Liberty Street, New York. In addition to the engines the vessel carried the same complement ofspars and .sails as a sailing ship of that period, with the excep- tion of royal raa.sts. The hull and rigging were constructed under the direction of Stevens Rogers, afterwards sailing master of the vessel. The most important difference noticeable in her rigging, so far as can be determined by engravings extant, is that her mainmast stood considerabl}' farther aft than it would have been placed on a ship intended to be propelled only by .sails. This modification of the rig was doubtless made to obtain more space between the foremast and the mainmast, so that the boilers, engines and coal bunkers could be located nearlj' in the middle of the ship and still be forward of the maiimiast. The New York Mercantile Advertiser, March 27, 1819, contained the following; " The new .steamship Savannah is to lea\'e our harbor to morrow. Who would have had the cour- age 20 years ago to hazard a prediction that in the year 1819 a ship of 300 tons burden would be built in the port of New York to navigate the Atlantic propelled by steam ? With admiring thou.sands have we repeatedly viewed this prodigy." Moses Rogers, the captain, and Stevens Rogers, the first officer (or sailing-ma.ster, as he was called), although bearing the same surname, were not related by ties of blood. Theywere, how- ever, brothers-in-law, the latter having married a sister of the former. Both men were born in New London, Conn., where the latter died in August, j868. The well-known captain was also chief engineer. The voyage to Liverpool, England, was made in 22 days, 14 of the 22 under steam. She then visited several of the continental ports of Europe before returning to the United States. The great fire in Savannah in January, 1820, brought pecuniary embarrassment upon her owners, who, failing in their efforts to sell the vessel to the Government, were compelled to dispose of her elsewhere. Her engines were removed and sold to the Allaire Iron Works, of New York, for $1,600, and put to other purposes. In the Cry.stal Palace exhibition of 1856, the 40-nich cyhnder was exhibited as an historical relic in con- nection with the log-book. After the vessel was divested of her engines, she ran between New York and Savannah as a .sailing packet for .several years. She ran ashore on Long Lsland and went to pieces in 1S22, a few months after the death of her commander.

Induced or suction draft maj^ be defined as natural draft intensified; that is, there are no difficulties arising from its u.se that would not be met with in the use of natural draft with a high funnel. In a forced draft sy.stem the pressure of the air is behind the gases, which are driven against the plate on the opposite side of the combustion chamber and left to find their waj' into the tubes as best they can. An undue heating of the tube sheet between the tubes takes place, and leakage at the tube ends results. With the induced draft S5',steni the gases are led into the tubes in streams as the}' come from the furnace, and there is little or no difference between the temperature of the tube sheet and the tube ends, and trouble from leakage is avoided. In the power plant of the American Line, at the foot of Fulton Street, North River, New York, are two boilers of the Scotch marine type, precisely' alike in all respects except that one is fitted with 31'4-inch outside diameter plain tubes with retarders, and the other with 334^-inch Serve ribbed tubes with retarders, both being used in combination with the Ellis & Eaves suction draft .sy.stem, for which Charles W. Whitney, of 66 Broadway, New York, is the sole agent for the United States and Canada.

The illustration is a reproduction from an excellent photo- graph of the Nottingham, which is the largest and most com- pletely equipped steel tug ever con.structed in the United States for towing only. She was designed throughout by H. C. Wintringham, Havemeyer Building, New York, as he has made a special study of tugboat recpurements, and was built under his personal super\'ision b> John H. Dialogue & Son, Camden, N. J., for the Central Railroad of New Jersey. She is u.sed for towing coal barges between New York and points on the New England coa.st from Boston east. The Nottingham is 140 feet long over all, 27 feet beam and 17 feet depth of hold. She is built of .steel throughout, mckiding the deck hou.se, and has three complete water-tight bulkheads dividing the hull into four compartments, and two partial bulkheads, one of which can be made water-tight by closing and fastening one steel door. The steel deck house is lighted and ventilated by large side lights and contains, in addition to the upper engine-room and boiler-room, the galley, pantry and me.ss- room, and .staterooms for the chief engineer, second engineer and mate. There are two boilers of the Scotch t)-pe, each i r feet long and 132 inches diameter, with two corrugated .steel furnaces". The bunkers have a capacity for 156 tons of coal. The engine is of neat design with the condenser in the back frame, and an open front supported on finished steel columns; it is triple-expansion, the cylinders being ifi'j, 24 and 41 inches in diameters, and 3(j inches stroke. Tlie high and in- termediate-pressure valves are piston \'alves and the low-pres- sure valve a double-ported slide valve. The power is equally divided among the three cylinders, and as there are no pumps driven from the main engine, its motion is very even and free from viljration. It has a steam reversing gear, and is handled from the lower engine-room. There is a sanitary and bilge- pump, which is kept at work continuall>- forcing water to all parts of the vessel. There are also fire and donkey-pumps. All the pumps are separate and independent, and steam can be kept up without running the main engine or wa.sting water, and the auxiliary engines exhaust into the conden.ser. Mr. Wintring- ham, the designer of the Ijoat, has given unusual attention to proiiortioning and arranging all details of hull and machinery, and has succeeded in producing a tug which is economical and satisfactory in ever>- particular and in advance of the usual practice. The Nottingham receives her name from a very celebrated brand of Pennsylvania coal, the mines of which are owned by the Central Railroad of New Jersey. On her after smokestack she carries the company s mark— a white disc with red center. HOWKI.L'S STEAM VluSSELS AND MARINE ENGINIvS. 35 I t i ii l i ll W l il i lW Thfc Norwich Lini^'s Stkki.

The hull ot the vessel is coii.structed entirelv of steel with four complete water-tight bulkheads. She has five decks, named, respec- tively lower, mam, saloon, gallery and hurricane. The pro- pelling power consists of two independent sets of vertical, in- verted, direct-acting, triple-expansion engines, driving ^twm screws The cvlinders are 26. 40 and 64 Ijy ,V>. the high- pressure being fitted with a piston valve, and the intermediate and low-pressure cvlinders with double-ported slides. The total indicated horse-power, including all auxiliaries, is 4.650 when the main engines are making 125 revolutions per minute, a piston speed of about 750 feet. The cylinders are supported by heavy wrought-iron columns in front and cast-steel columns behind. The piston-rods are of steel, whilst the connecting and all working rods generally are of wrought iron. The air- pumps are worked from the low-pressure crosshead, and are of 27-inch diameter witli 12-inch stroke. The condensers are constructed of composition, and have each a cooling surface of .1.3^7 square feet. The crank shaft is 1 1 ^4 inches diameter, and is made of wrought iron with steel crank pins. The pro- peller wheels are constructed of manganese-bronze, they being four-ljladed and 11 feet diameter, with a pitch of about 16 feet. Steam is supplied by six steel single-ended Scotch return tubu- lar boilers, each having a length of 12 feet 10 inches and a diameter of 13 feet 6 inches. They have each three corru- gated furnaces of 43 inches internal diameter, and are designed for a working pressure of 165 pounds to the square inch. The boilers are placed three on the starboard and three on the port side of a boiler-room the width of the ship, and are 44 feet long, and two tall smoke.stacks, 9 b}^ 7 '_. feet, carry off the refuse gas and smoke. The engines, boilers and coal take up 74 feet of the vessel's length amidships, the total coal bunker capacity being 90 tons, sufficient for the vessel to steam one round trip. The propelling machinery was designed by Chas. E. Hyde.

It is only recently that the screw has begun to replace the sidewheel in the passenger service on Long Island Sound. How well the twin screw is adapted to the requirements of that service, in the speed attained and ease of manipula- tion in the crowded waters of the East River, is de- monstrated by the success of the Richard Peck, of the New Haven Line, which created quite a sensation at the time of its addition to the fleet a few years ago. Her length on the water line is 300 feet ; over all, 316 feet ; beam, 48 feet ; breadth over guards, 62 feet ; depth of hold, 18 '2 feet. It is in the motive power that our readers will be chiefly interested. This is fur- nished by two triple-expansion engines having 24, 38 and 60- inch cylinders, and a 30-inch stroke, run regularh^ at 136 revo- lutions per minute, or 680 feet of piston .speed, and developing, with an initial pressure of 160 pounds, about 4,250 indicated horse-power. A good idea of their general appearance and their arrangement with reference to the boilers, etc., is con- veyed by the engraving. The valves are controlled by ordinary marine link motions operated by means of a steam ram, a single stroke of which shifts the blocks through the entire length of the links. The steam rams are operated by the small levers shown in the center of both engines, and so easily are they manipulated that one man standing between the engines can operate both. Piston valves 12 inches in diameter are used on the high-pressure cylinders, and slide valves on the interme- diate and low, those on the low-pressure being double-ported. The valves weigh as follows : high-pressure, 200 pounds ; intermediate, 700; low-pressure, about 1,000 pounds. The weight of the slide valve is taken up b}' pistons working in vertical cylinders over the valves, subjected to the steam chest or receiver pressure below and connected with the condenser above. There are also provided equalizing valves on all the C3dinders allowin.g the .steam to escape to the chest or receiver should the pressure in the cylinder exceed, by compression or otherwise, the available initial pressure. Each engine has its own surface condenser of the type ordinarily furnished by the builders of the hull and machinery, the Harlan & HoUingsworth Company, of Wilmington, Del. These are parallel with the engines and behind them. The circulating water is supplied by centrifugal pumps, one for each engine, operated by small vertical engines, directly connected to the pump shafts. Should an accident occcur to the circulating apparatus or the surface conden,ser a jet maj^ be used, and an escape valve is provided for automatically discharging the exhaust to the atmosphere in case of the total disabling of the condenser. The air-pumps are vertical single-acting, operated by beams receiving their motion from the low-pressure crossheads. Two bilge-pumps are also attached to each beam. From the hot-well the water is passed throu.gh a hay filter and returned to the boilers by a 10 b)' 6 by 12-inch Blake feed-pump, the speed of which is 38 HDWKLL'S STEAM V]{SSELS AND MARINE ENGINEvS. controlled b^- a Waters pnnip governor operated by a float in the filter tank. The exhaust from the Ijoiler feed-pump is turned into the tank, raising the temperature of the feed some 50 degrees. Two Korting I'niversal injectors are used for forcing water iv.nu the fresh-water tanks to the boilers when the engines are not in operation, A b)'-pass is provided between the steam and water compartments of the surface condensers, by opening which salt water mav be added to the condensed steam to make up lo.s.ses, etc. There are also small Blake water-jacketed, and have also spray pipes for emergencies. Steam is furnished by six steel Scotch boilers 13 feet in diameter and 12 feet long, with three furnaces each. The furnaces are of corrugated steel, and furnished by the Continental Iron Works, Brooklyn, N, V,, and since boilers of the Scotch type are coming into considerable use in stationary' practice, will interest as well the stationary engineer.

The channel iron system of construction is excellently shown in the accompanying illustration, which pictures the methods employed in the building of a large steel steamer on the lakes. There has been a good deal of controvensy pro and con upon the merits of this system, as compared with the old style of using angel irons on steel plates. The channel SNstem is the invention of Sinclair Stuart, Ship and Engineer Surveyor to U. S. Standard Steamship Owners', Builders' and Underwriters' Association, Limited, British Corporation for the Survey and Registry of Shipping, and LInited States Lloyds, New York, and has been used in the yards of the Cleveland Shipbuilding Co., the Chicago Shipbuilding Co., and others. The channel system certainly saves a large amount of riveting, and its advocates claim that it gives the .ship a greater rigidity where it is most needed, and where rivet heads shear off most. The saving in rivets is effected by riveting the flanges of the channeled iron together direct instead of using angle pieces. The illustration shows the turn of the bilge in the foreground, no frames being yet set up. The frames will at- tach where the temporary wooden stringer is seen. The cut shows more clearly than any description of the work that might be written how these channel shapes are used for main frames and floor plates, instead of angle iron and plates riveted together to form the desired shape.— Cleveland Marine Record.

The cranks are jilaced di- rectly opposite, the object of the receiver being to do awa\' with the shock and pound in the Imv-pressure cylinder, common in engines exhausting directly from high-]iressure into low- pressure c\linder when running at a high rate of speed. The valve is in one casting, consisting of four discs on a central colunui. Steam enters tile chest between the two inside discs, the Course of the steam lieing shown b\- the arrows. The ex- haust ports at the top and bottom of the steam chest run into each other at the l.)ack of the chest, and the exhaust steam is carried away by one ]>ipe. The steam pipe is 2' ■ inches diameter and the exhaust 3 ' _■ inches. The steam chest is fitted with a cast-iron liner. The liner has bridges across the exhaust ports, and jjieces cut - horizontal columns going through T's on the main columns, with a nut on each side. The opposite guides are connected, but not shown in drawing, tying the columns together, making a light and very rigid frame. The guides are fitted with brass slippers. The con- necting-rods are 12'.. inches between centers, ha\-ing eyes in the upper end with solid brass bushings pressed in. The lower end has the regular box. The crank shaft is of steel 2 ' _- inches diameter. There are four main bearings, two 4 inches and two 31, inches long, all fitted with brass bushings. The reversing ^rear is the regular double-bar link motion. The go-ahead eccentric rod is' .straight, the off-set coming altogether on the back-up rod. The top cylinder heads have a -=s-inch ground joint. The guides are adjustable by the nuts of the columns. The thrust has three collars running in a bearing cast on the bedplate. The thrust bearing is babbitted. The bedplate is cast iron, very strong and light. The engine was designed to meet specifications calling for a compound engine of the given size cvliiulers, to make 750 rc\-olulions and occupy little space. The crank shaft, set as it is, does awa\- with all pocketing of .steam 111 the receiver, to be held there in compres.sion till the low-pressure pi.ston is in a po.sition to take it ; but the in.stant the high-pressure cylinder has finished with its steam, the low- pressure is ready to take it without further compression, hi- creasiug the cfiicieiic\- of the engine besides making a very nice balance". Steam enters the chest and is delivered direct into the high-pressure cylinder ; after it has done its work there, it is delivered almost in a straight line across to the low-pressure and from there into the ci ndeiiser. Although two cylinders are run with one valve, the port passages are no longer than other engines and .shorter than most. The valve is \"ery .simple, finished in one setting in the lathe, making it \-er>- cheap to build, and, at the same time, a good job. There are no diflicult or delicate parts about the engine, and is \'er>' eas>- to handle. The speed at wliich engines of this t>pe can be run .surprises all who see them.

The latter has a cooling surface of 1,125 square feet. The tube heads are of brass, provided with stuffing boxes, which are packed with corset lacing, and held in place by .screw glands. The air-pump is 18 inches \n diameter by 14 inches stroke. There is one bilge-pump and two feed-pumps, the latter being 3':; inches in diameter each, and provided with automatic safety relief valves ; all worked by wrought-iron beams connected to the low-pressure crosshead. The vessel i.s of .steel, 122 feet long by 25 feet beam, and has a draught of II feet 9 inches.

The London and North Western Railroad Co.'s express paddle steamer Banshee was fitted in 1S94 b}' Laird Bros., Birk- enhead, England, with new machinery on the tri-compound system, after the pattern of that made by the same firm for her sister boats, Lily and Violet, several years ago. On her trial trip from Holyhead to Kish Light the rnn occupied 2 hours 21 minutes, the engines making 36 revolutions with 4,750 in- dicated horse-power, the return run against the tide with a rough beam sea atid southerly breeze occupied exactly the same time with 38 revolutions and 5, 150 indicated hor.se-povver, the speed for the whole time being 20.42 knots. There is remark- ably little vibration, and the vessel is extremely handy. The machinery consists of a set of triple-e.xpansion steeple engines. The cylinders are bolted, without the intervention of any bed- plate to the engine-room keelsons, by ordinary holding down bolts, and secured to the entablature above by wrought-iron columns. The cylinders are placed in line athwartships, the low-pressure being in the middle, the high-pressure on the port side, and the medium-pressure on the starboard side. The pistons and piston-rods, the bowstring cro.sshead pieces, and the connecting-rods, as well as other parts, are of steel. Owing to the small athwartships space in which it was necessary to place the three cranks, the vah-e chests are placed on the aft side and eccentric motion dispensed with. The type of valve gear adopted is Joy's, which is well known as possessing the good point of occupying little room. Piston valves are used for the high-pressure and medium-pressure engines, and a balanced D-slide for the low-pre.ssure engine. The reversing gear is attached to the upper framing which supports the guides, and is worked by a .steam and h3'draulic engine. The crank pins, crank shafting, and paddle shafting are of hollow steel. All the bearings have a very large wearing surface. The condenser is placed in the fore part of the engine-room. The circulating water is supplied to it b\- a 16 '2 -inch centri- fugal pump driven by a compound engine. The air-pumps are of a special design. There is a vertical triple-expansion engine placed immediately over the three air-pump c}'linders, each steam cylinder and pump cylinder being in line, the crank shaft being placed between. The main feed-pump is .separate, and there are also auxiliary steam feed-pumps, bilge and fire- pumps. Steam is generated in six boilers of the locomotive marine type, at a pres,sure of 155 pounds to the square inch. They are placed in two groups of three each, in two closed stokeholds. Air is supplied to the furnaces by two large fans, situated on the upper deck, driven by two sets of compound vertical engines. The air pressure is i^ inch of water. The paddle-wheels are fitted with curved steel floats of special design. The dimensions of the new engines are as follows : Cyl- inders, 44, 70 and 108 inches by 78 inches stroke. The old engines were of the oscillating type, with two cylinders 80 inches in diameter, 84 inches stroke. The Banshee's dimen- sions are : Length, between perpendiculars, 310 feet ; beam, 34 feet ; depth of hold, 14 feet 2 inches, and she has a gross register tonnage of 1,249 tons. Her working draught is about II feet 3 inches. The Banshee runs between Holyliead, Wales, and Dublin, Ireland, carrying passengers and the mail. An unusual compound engine, built by W D. Eorbes & Co., of 1304 Hudson vStreet, Lloboken, New Jersey, is shown in the cut. This engine contains no new principles, its claim to note being ba.sed on constructive details. The usual heavy stanchions are eliminated, two-inch bars of machine steel being substituted. These are braced diagonally by tension rods pro- vided with a turn buckle for increasing the stress, as plainly shown. This gives the engine a very neat and light appearance combined with the requisite strength. The usual round section coriuecting-rod is dispensed ^\ith, the stuffing boxes are unusually long, the guides are a departure from the usual types and are furnished with adju.stable bronze .shoes. The l;earin,gs are large and preclude all possibility of heating or excessive wear. It is a high-speed engine, running at 450 revolutions, and develops from 125 to 150 horse-power, the cylinders being 8 by 16, and the stroke 10 inches. The floor .space is very small for an engine of this pov/er, being 44 by 36 inches, while the height is 74 inches, thus making it especially desirable where a small space only can be devoted to power. Messrs. Forbes & Company have installed these engines in several 70-foot launches with great success. — Power, New York. Hayes' Compound Marine Engine. The cut represents one of the sizes of Hayes' compound sur- face-condensing engines suited for tugs, yachts or launches. These engines are designed and built by Edward Hayes, vStony Stratford, Buckshire, Woherton, England. The engine shown is intended for the .severest description of work in towing, and for heavy .steam launches where considerable power in running is necessary. The surface condenser is fitted with brass tubes and tube plates, the tube ends being secured by screw glands with cotton washer packing. The slide valves, steam ports, passages, and the chamber of C)"linder, have proved themselves to be of the best proportions. This type of engine was placed in the steam yacht Regalia, which, it will be remembered, won the international .steam yacht race on the Paris course at Argentenie, in June, 18S9. The Smit Harine Engine. This triple-expansion engine was designed and built \iy P. Smit, Jr., of Rotterdam, Holland, and is of 130 horse-power. The high-pressure cylinder has a diameter of 8 inches, the in- termediate cylinder of 12 inches, the low-pressure of 20 inches, all with the same stroke of 14 inches. The diameters are cal- culated for a boiler pressure of 150 pounds. According to the diagrams, the power is nearl}' equally divided. With 185 revo- lutions per minute, the high-pressure cylinder gave out 45.4 indicated horse-power ; intermediate, 42 indicated horse-power ; and the low-pressure, 44 35 indicated horse-power, or a total of 131.75 indicated hor.se-power. These engines consume but a little quantity of coal, as on the trial trip it onlj" amounted to 34 kilograms, or nearly 0.64 kilogram per indicated horse-power, which is very low for .so small an engine. The novelty of these engines is the movement of the slide valves which, simple in ss HOWELL'S STEAM A'ESSELS AND MARINE ENGINES. The Haves Compounh INIarink En(;ike. itself, gives a very compact engine, as the cylinders may be as close together as is consistent with the combination of the cyl- inders through flanges bolted to each other. The slide valves are moved by a common eccentric, which is cast on a sleeve of cast steel, in which is turned a hole, through which the inner shaft runs. This .shaft is rotated by two cranks or pins fastened to the outer flanges, which get their rotation from eccentrics keyed to the crank shaft of the engine. The engine is reversed by backing the handle, which is placed on a casting on the foundation. This lever moves the cast-steel sleeve in the usual way, which turns the eccentrics of the slide valves to the opposite angle and reverses the engine. These engines are made in all sizes up to looo indicated honse-power. The larger ones are fitted with steam reversing gear, and may be made with link motion without altering the system. The cylinders are coated with non-conducting material over which cast-iron mantles are fitted to form a neat and solid appearance. The Seabury Triple-Expansion Yacht Engine. Chas. L. Seabury & Co., Nyack, N. Y., have been careful in designing a triple-expansion engine to combine all the best qualities of that class of engine; also to reduce its weight to the minimum, yet having necessary strength. They are accurately proportioned to give equal power from each cylinder, great care being taken to have no superfluous metal in the revolving HOWEI.L'S STEAM VESSEIvS AND MARINE ENGINES. 59 Triple-Expansion En(;ini?. — Designed and Built by P. Sinit, Jr., Rotterdam. parts, allowing a large factor for safet}-; therefore a high rotative speed can be had with very little noise or vibration. The bedplate is of close-grained cast iron, of the best design, and strongly webbed throughout. The main bearings are lined with the very be.st Babbitt metal, scraped to crank shaft. Crank shaft, valve shaft, stanchions, valve rods, piston-rods, braces, rails and levers are made from solid steel stock of best quality. Connecting-rods and eccentric-rods are forged from solid steel without welds. All are finished bright and polished. The crank pin boxes are of be,st bronze, lined with Babbitt metal. Crossheads are of bronze running in cast-iron slides; all bearings and wearing surfaces are made extra large, as thej^ are built for heavy and continuous work ; bearings are also ar- ranged for taking up all wear. All main bearings, crank pin bearings and crosshead pin bearing bolts are provided with a simple arrangement for preventing slacking off when running. The thrust bearing is made by turning collars on crank shaft running in Babbitt-lined grooves in bedplate. Air-pump is made of bronze and is operated from low-pressure cylinder. The cylinders are made of the best fine-grained cast iron, bored true and fitted with steel pistons and cast-iron rings ; bushings are also fitted for piston valves which are used, as greater ac- 6o HOWELL'S STEAM VESSELS AND MARINE ENGINES.

Relief valves and drip pipes are fitted to each end of all cylinders. The engines are neatly jacketed in brass and mahogany. Two hundred and twenty to 240 pounds of steam should be carried to get eco- nomical results, although they have numbers of them running with 275 pounds. They also build compound and simple engines for marine work. Have built a large number for blower and electric light purposes, some of these having run 2,000 revolutions per minute. The Wheeler Surface Condenser. The " Wheeler-Admiralty " surface condenser differs from the "Wheeler-Standard" in that it has .single instead of double tubes. These tubes, however, are arranged in a special manner, thereby securing minimum number of joints liable to leak, with ample provision for expansion and contraction. As shown by sectional cut above, one end of the tube is drawn thick enough to chase upon it deep screw threads, and has a slot for a .screw driving tool. The other end of the tube is packed with corset lace packing, secured by a screw gland also having a slot for screw driver tool ; the tube can move freely at this end while the other end is held firmly in the tube head. Where customers prefer the ordinary arrangement of screw glands at both ends of the tubes, packed with the usual corset lace packing and secured with patent .screw glands, the manufacturers can always accommodate them, as their regular pattern of " Wheeler- Admiralty " surface conden.ser is so ar- ranged. The Wheeler patent surface conden.ser known as the "Wheeler-Standard," and which has been in successful use for years, is the result of extensive and wide experience in this special line. It combines the necessary' theoretical qualifications with thoroughly practical features. Briefly .stated, Wheeler's improved surface condenser possesses the following advantages, vis . . First. — The tubes are so arranged that they are free to expand and contract without the use of packings of paper, wood or .similar materials ; in fact, there are no ferrules, fol- lowers, washers or tube packings of any kind employed. Plain screw joints only are u.sed — the simplest, most durable and efficient tube fastening possible, one that is always tight and cannot dry out or wear out. ^ Second. — The tubes are straight, of seamless drawn brass tubing, and carefully tinned inside and outside. They can be easily taken out and thoroughly cleaned in a few hours' time by unskilled labor. The inside tube head does not have to be removed from the condenser for the cleaning or repairing of the large tubes. T/n?-d. — The exhaust steam , as it enters the condenser, finds ample room in which to expand, and is then uniformly dis- tributed over the cooling surface. This, together with a very active and perfect circulation of condensing water in tiie tubes.

The Wheeler light-weight surface condenser is applied to small steam vessels, where the minimum of weight and space are combined with simplicity and greatest efficiencj-. These improved condensers are made in the smaller sizes, with shells of brass or hammered copper. The tubes are of seamless brass, well tinned inside and outside, and are drawn with great care. These tubes are screwed into the tube heads, thus making tight and durable joints, a verj' important feature for conden.sers that are out of use a large part of the year, as in the case of steam yachts, etc. There are no ferrules, washers, tube packings, etc., to leak or dry out. These condensers combine minimum weight with maximum efficiency ; they are more satisfactory' and quite as inexpensive as keel ( outboard pipe ) condensers, and will give the hot feed- water — an impossibility with the latter form of condenser. The substitution of a Wheeler light-weight surface con- denser for the keel condenser also removes a great impediment to the speed of a boat. The keel condenser not only gives chilled feed-water and unsteady vacuum, but is always a source of trouble and liable to damage from collision with floating matter or by the boat running aground. For launches, steam yachts and light-draught steam vessels plying in fresh water, the Wheeler light-weight jet condenser is the simplest and most compact condenser in the market. In weight it is remarkably light — an important consideration. It can be attached to a connected air-pump and worked by the main engine, or it can be arranged with an independent air- pump. The latter is a better plan, as vacuum can be formed for the main engine before starting it, and being independent the speed of the pump can be regulated to suit the demands of the engine. With the high rate of speed that marine engines are now run at it is a great disadvantage to have connected air-pumps. The Wheeler light-weight jet condenser is a shell of ham- mered copper or galvanized iron — the exhaust steam pipe, the injection pipe and the pipe that connects the condenser with the air-pump are all attached to the large head, which is a casting made exceedingly light and strong. The injection water is thoroughly distributed by means of a perforated spray pipe extending through the centre of the condenser. One end of this spra3' pipe is firmly attached to the small flange, on the outer side of which is a convenient handle (see left-hand end of conden.ser in cutj ; the other end of spray pipe fits over a nozzle cast on the inner side of the large head, and which projects into the condenser a short distance, thus forming a continuance of the injection pipe outside. When necessary to clean the spray pipe from dirt, chips or grass brought in by the injection water, all that is required is to unbolt the small flange and by means of the handle draw out the .spray pipe. This convenient feature avoids disturbing any of the piping, and gives easy access to the interior of the condenser. The Wheeler Condenser and Engineering Company, New York, are the builders of these condensers. HOWKIX'S STEAM A'ESSELS AND >L\RINE ENGINES. Thk \'oi,z Patknt CoMBiMKn Surface Condenser and Feed-Water Heaticr. The Volz Patent Combined Surface Condenser and Feed- Water Heater. Marine and stationary engineers using surface condensers are well aware of the difficult5' of retaining the feed-water in the hot-well at or near the proper temperature due to the vacuum in condenser, particularly in cold weather. The water of condensation neces.sarily lowers its temperature as it passes from the condenser through the air-pump, and from thence to the hot-well, filter tank and through the feed-pump, as there is considerable radiation of heat from the pipes and other surfaces. As it is very desirable to return the feed- water to the boilers at as high a temperature as po.ssible, thus not only economizing fuel but adding to the life of the boiler, the use of a simple and effective method of heating the feed- water is of great importance. The A'olz patent combined .sur- face conden.ser and feed-water heater fully meets this condition and is very simple in design. It adds but little extra cost and .space, and a high vacuum can l)e maintained, irrespective of temperature of hot-well; it has given the mo.st satisfactory re- sults on board of .steam vessels. The heater tubes are located in the upper part of the conden.ser, and therefore are exposed to the hottest steam. The feed-water is consecjuentlj' heated to within a few degrees of the temperature of the exhau.st .steam. There is no " choking" of the e.xhaust steam through small and contracted passages as with ordinary heaters, and there is no unnecessary back pressure on the feed-pumps. A large amount of heating surface is obtained, whether the condenser is built either cylindrical or rectangular; furthermore, the weight and .space sa^-ed over that required for the ordinary heater (sometimes crowded in exhau.st pipe) is of considerable value. The engravings show a sectional view and end view (tubes partly exposed) of the patented combined surface con- denser and feed-water heater, cylindrical type. The exhaust steam enters through the top opening in the usual way, passes (Aer a scattering plate and then comes in contact first with the heater tubes and then with the condenser tubes, where after con- densation, it flows to the air-pump, which in turn delivers it to the hot-well tank. The feed-water is taken by the feed-pump from hot-well and delivered near the top of the upper or feed chamber, as shown by the arrows, then passes twice through the heater tubes and finally to boilers. The circulating water enters the water chamber at the lower nozzle, as .shown, and after passing through the conden.sing tubes is discharged through the upper nozzle at the .same end of the condenser. An auto- matic relief valve is placed on top of conden,ser, the vacuum always keeping it clo.sed. The tubes of both heater and con- denser are of seamless drawn brass, tinned on both sides, with ferrules at each end properly packed. The shell of condenser is usually cast iron. The water chambers and tube heads are made in one composition casting, with the division plates .separ- ating the feed from the circulating water cast in, thus avoid- ing joints. This feed chamber is made to withstand boiler pre,ssure. Free access to the tubes is provided by the ar- rangement of separate bonnets or heads. The WHieeler Con- denser and Engineering Co., New York, are the builders of the above de\-ice. The inventor and patentee is Wm. E. Volz. Wells' Balanced Compound and Ouadruple=Expansic Engine. In order to balance all forces it must be a natural balance This can only be accomplished bv a double action, where equal steani pressures are exerted simultaneouslv on opposite cylinder heads, and where all forces are equally applied to opposite sides ot the crank .shaft moving in the .same plane. Anv deviafon from the plane produces disturbing and destructive elements The \\ells .system represents the onlv improvement in principle that has ever been made. The important advantages derived from a balance of forces in the steam engine were pratically unknown until demonstrated by this sy.stem for the HOWElJ.'vS STEAM VliSSELS AND MARINIC ENGINES. Wkhs' Patent Ouadruple-Expansion Engine. rea,son that all engine.s con,structed with a " balance" in view embraced grave mechanical objections. Hence, the .single- acting ' ' unbalanced' ' reciprocating engine is the onl}"- system that has proved to be of any value. While the Wells engine embraces all of the desirable features of the most approved type in general use, it contains none of its objections. It is double acting and so designed that all forces acting in the high-pressure cylinder are held in proper position by the forces acting in the low-pressure cylinder, producing k perfect balance around the crank shaft, and preventing vibration and the escape or loss of power that in all other engines is thrown off through the frame into the foundation. BALANCED STEAM PRES.SUEES. We desire to call especial attention to this important feature (not contained in any other engine) , as it would be impossible to obtain a balance without it. Steam is admitted to both cylinders simultaneously ; during the first stroke, the steam pressures upon the middle cylinder head are exerted against each other ; the force acting upward in the high-pressure c}linder becomes the support of the force act- ing downward in the low-pressure cylinder. In the return .stroke the pressures are exerted upon the top and bottom cylinder heads in opposite directions, giving a balance of pressures within the cylinders — a condition that applies to no other type 64 HOW-ELL'S STEAM VESSELS AND MARINE ENGINES. iffi] o Weli,s' Patent Balanced Engini;. of eno-ine, as no strains are communicated to the frame and bedplate. B.ALANCED FORCE.S AND MOTIONS. The force of the steam applied to the high-pressure piston descending upon one side of the shaft is balanced by the force of the steam applied to the low-pressure pi.ston ascending upon the other side, leaving only the weight of the crank shaft and its connections to be carried by the mam bearing boxes. Each motion in this eiioTue has a corresponding oppo.site motion producing a perfect balance at all angles of the cranks and at all speeds. By this arrangement no strains escape from the cylinders, and the connecting-rods and cranks become the sole transmitters and controllers of all forces. It also trans'"ers the fulcrum from the main bearing boxes to the center of the shaft. The weights and forces being equally applied to oppo- site crank pins, moving in opposite direction;; in the same plane the cranks become the beams, or levers of balance, and there being no weight of parts to be lifted and no friction due to steam pressures to overcome ; the steam forces applied to the pistons and the momentum foices stored in its mo^ ing parts are all transformed into crank motion. Its absolute control of these HOWELL'S STEAM VESSIU.S AND MARINr: ENGINES. 65 Chase's Ouauruple-Expansion Marine Engine. force,s, for useful effect, greatly increases the power of the engine. It also gives uniforniit}' of motion, its forces being equal around the circuit of the shaft ; they are gi\-en out in the crank arms when the steam forces are diminishing, as the pistons are approaching the end of the stroke, acting the same as an ordin- ary fly-wheel in carrying them over the centers, producing a rotary motion. ITS GREAT IMPORTANCE IN LARGE POWERS. This principle embraces a very peculiar feature, directly the reverse of the general practice, which is of the highest import- ance ; i. e., the advantages gained by balancing the forces in the Wells engine increase in direct ratio with the bore of cylinder (tons being balanced in large, versus pounds in small engines ), while the losses from unbalanced disturbing forces in all other engines increase in the same ratio. Therefore, the greater the power, the more important it is to obtain a balance; and the relief of pressures afforded in the main bearing boxes by this system will readily be seen by multiplying the area of piston with the mean steam pressure, and the weight of the recipro- cating parts by their velocity-. For example, take an engine with cylinders 18 inches and 36 inches diameter with a mean steam pressure of 30 pounds, and a piston speed of 600 feet per minute, it relieves the main bearings of 19 tons pressure per stroke of pistons. The principle embraces the most favorable conditions for the construction of large engines ; the " balanced" double-act- ing levers, or cranks, have only their weight and that of the 66 HOWKLL'S STEAM A-ESSELS AND MARINE ENGINES. rods to support between the main bearings, as they are relieved from the weight of the steam and the thrust of the rods. The forces being all transmitted in torsion, they have no tendenc>- to leave their proper positions. OrADKUFLEU. Two of these engines coupled closel_\' together in one frame, each with cranks set at iSo°, they occupy no more space than the ordinary fore-and-aft compound, and one-third 1 ess space than the triple, and embrace all of the advantages named in the foregoing description of the principle. To those who are not familiar with this principle some concep- tion of its \-ast importance may be gained by carefully calcu- lating the useful effect of a perfect balance in the propelling forces, when applied to a ship equal in power to the Majestic where the combinded area of the two low-pressure pistons is 20,414 inches multiplied b\' a mean steam pressure of 27'j pounds gives a pressure of 2S0 tons per stroke of pistons ; sup- posing the moving parts of the engine to wei.gh 60 tons and to have a velocity of 870 inches per minute, gives a further pres- sure of 600 tons per stroke or 320 tons in excess of the total steam pressure, and a condjined pressure of loSo tons per stroke, that must be resisted (that heretofore has never been controlled ) by the engine frame bedplate hull of the ship, and finall}' by the ocean itself, into which a large percentage of the power escapes. By the Wells system all forces are concentrated in the crank shaft, which prevent any escape, and at same time it relieves the engine frame and hull of all strains and \-ibration and the journals from heating. DURAllILITY AND CONSTRUCTION. Unbalanced weight in motion ( momemtum ) being the onh- element that tends to destroy an engine ; makes it apparent that balanced weights, balanced steam pressures, and balanced motions are the qualifications nece.s.sary to produce a durable engine, all of which this design possesses in the highest degree. Practice proves it to be far more durable than an}' ever con- structed ; although subjected to extreme pressures and speeds, so far no part of the engine has failed, which is easily accounted for from the fact that all forces being perfectl}' balanced obvi- ates vibration, injurious strains, and unnecessarj' friction, the only elements that tend to destroy the machine. Relieved of the pressure, the life of the main bearing br)xes becomes prac- tically unlimited, and the little wear that occurs on the main journals will be evenh- distributed around their whole circum- ferance. These engines are built by the Wells Engine Com- pany, New York, from designs of Justin R. Wells. Chase's Quadruple=Expansion Marine Engine. The.se illustrations are taken from a working model of a disconnective quadruple-expansion marine engine built to a 34-inch scale by Erank Chase, of Hartford, Conn, The principal dimensions of the full-sized engine would be : Diameter of high-pressure cylinder, 14 inches; first inter- mediate, 22 inches ; second intermediate, ,^2 inches ; low- pressure, 45 inches ; stroke, 2S inches. Boiler pressure, 200 pounds per square inch. The engine is arranged on the tandem principle, the high-pressure and first intermediate cvlinders forming the forward engine, the .second intermediate and low-pressure cylinders the after engine. The cylinders are jacketed with steam direct from the boiler, entering through an inlet valve and dropped into condenser. This enables them to be thoroughly heated before^opening the throttle. At the same time a vacuum may be^produced by starting up the circidating donkey-pump. In addition to the steam jacket is Ch.\SE'S Y.AI.VB ("xli.JiK AND M.iKINi; G(.>\'F;RN( )R . a coating of a.sbe.stos, and a lagging of alternate strips of ma- hogany and white maple, which last has an effective appear- ance. The relief valves at each end of cylinders are made extra large ; ample pnjvision for draining cylinders and jackets is provided, together with indicator cocks and Gonnec- tKHis. The main valves are all of the piston tvpe, and their upper portions in the upper cylinders are made slightly larger ; this excess in area perfectly balances all the valve gearing beneath. The cylinder pistons are attached to their rods by means of an adjustable .screw collar. This arrangement has the same feature of rigidity as the usual conical rod and nut, but m case of accident, or for adjustment, allows the pi.ston to be readily removed. The pi.ston-rods to the lower cylinders are made considerably smaller than usual bv this method thus .slightly increasing the effective cvlinder area. The stuffing b.ixes between the upper and lower c^dinders are each made in two halves, bolted together, and furnished with split collar bushes. A long sleeve is utilized in place of one set of stuffing boxes ; the .sleeve also serves as as an excellent guide to the HOWKIX'vS STEAM VESSKLS AND MARINE ENGINEvS. 67 Aw.7We*«'r«iWfi? Chask's OTiAriRrpi.K-FIxPANSiON Rncinr. piston-rods. This arrangement dispenses with one set of stuffing bcsxes, shortens the distance between the cylinders, and enables obstinate cases of hard packing to be more readily dealt with. The upper C3-linders are supported on six vertical columns, any of which ma}' be readily removed for overhauling and repairs. The lower cylinders are supported at the back on the condenser, and in the front on cast-iron columns, the after column being utilized as an oil reservoir, and on this column the engine counter — which is of verj' simple construction — is attached. The go-ahead slides are detachable, and the shoes provided with brushes which dip into oil boxes at the foot of guides. The condenser is very efficient, the circulating water being circulated from the pump in two directions — around the condenser and through the tubes. Targe, easily accessible doors to the water side, with manhole and hand-holes to the steam side, are provided ; also snifting valve at lower point. All the pumps, excepting the donkey, are worked from the main engine. There are two feed-pumps with separate air vessels, stop and relief valves ; either pump is sufficient to supply the boiler under ordinary circumstances. Thev are l:)olted on considerably below the hot- well. The auxiliary feed may be connected either to the circu- lating water or to an evaporator. The air-pump is single acting, and placed low down on the condenser. The circulating- pump is double acting, and of sufficient capacitv for water of any temperature, the supply being, of course, 'regulated by main injection valve. There are also two bilge-pumps with their necessary stop valves and connections. All the pumps 6S HOWKLL'S STEAM VESSELS AND MARINE ENGINES. are supplied with pet cocks, and the hot-well with water guage, manhole and vapor pipe. The crank shaft is in two sections, flanged and secured in the center by a dowel, which can lie removed readily in case it is desired to run either engine separately. The main bear- ings have brass bushes in boxes ; also oil boxes and siphon pipes. The bearing surfaces throughout the engine are made extra large and well supplied with means of lubrication. The Allen .straight link. By the method of suspending this link a .sort of parallel motion'is obtained, which greatly reduces the slipping of the block, and gives a quicker admis.sion and cut-off. By means of a two-way valve to oil c>linder and lever to steam cylinder, reversing may be done (juickl)- or slowly, and the cut- off fixed immovable at any point. The hand reverser consists of a small force-pump connected with the oil vessel, utilizing the same le-i'ers "as the steam.

Back of the after-main bearing a gear wheel secured to .shaft engages with a worm driven from an auxiliary engine. By means of a clutch and swinging bracket the worm may be thrown out of gear without causing delay. The auxiliary engine, when not in use as a turning en.gine, serves as a powerful pump for all purposes. It has two double-acting steam c^dinders and pumps, and is remarkably compact. Slotted crossheads are used ; there are no eccentrics ; a cam on the shaft gives the necessary lead and cut-off when running in either direction, and reversing is eft'ected b>- re\-ersing the steam, all the pipes, etc., being cast with the cylinders and chests. The main engines are reversed either by hand or steam. Steam reversing engine consists of a steam and an oil cylinder, the pistons of which are connected together, and give motion bv links to the reversing gear, which is a modification of the re\-ersing gear is a po.sitive governor, T,'ery sensitive in its action, connected by gearing to the shaft, and having perfect control over the main engine. The cut will explain its action. Fig. I IS a general arrangement. Fig. 2 shows the balance valve to steam cylinder. Steam is admitted slightly to both .sides of piston, and a short movement of valve in either direction by the sensitive go^'ernor reduces the pressure on one .side of pi.ston, the latter, of course, following in the direction of the reduced pressure, and moving the connecting link to valve .spindle nearer to, or farther away from, the center of the slotted link, accord- ing to the speed of engine. The .same movement of the balanced valve opens the valve to oil cylinder as shown in Fig. 3. When the engine is at its normal .speed the oil piston is locked. Should any great acceleration of speed take place, due, for m.stance, to the breaking of the .shaft, the link would be thrown into mid gear, thus shutting off .steam completely from each and every cylinder in the main engine, nor would steam be again admitted except b\- operating the ordinary reversino- lever HOWEIX'S STKAM X'lvSSEIwS AND MARINE IvNGINEvS. 69 which is not in anj' way connected with the antoniatic .r^overnor. The disconnective features of the engine are as luHows : In case the forward engine breaks down, it is disconnected by removing the dowel in crank shaft. The vah-e between the two intermediate cyHnders, together with the throttle valve to high- pressure cylinder, is closed, and the auxihary pump used as a circulating pump. vSteam is admitted to the .second intermedi- ate cylinder through the reducing valve, and the after engine is run as a compound condensing engine. This reducing valve is operated by a lever from the starting platform, and isu.seful as a blow through \'alve for turning centers in starting. In case the after engine breaks down, the connecting-rod is removed from crank pin and secured in an out-of-the-way position. The valve between the two intermediate cylinders is clo.sed and con- nection made between first intermediate exhaust and condenser. The auxiliary pump is u.sed as an air-pump and the forward engine then run as a compound engine. The thrust fr(jm the propeller is taken up on conical r(jllers ruiuiing in oil, fitted with adjustable plates for wear ; this arrangement reduces the friction considerably. The engine takes up very little room fore and aft ; e\'ery part is accessible for adjustment and repairs, and a .system of duplication of parts is carried throughout. The Hartford (Cotniecticut) Steam I'oiler Inspection and Insurance Compan^■, is interested in the introdnction of this engine. Clark's Compound Yacht Engine. The two views are from photographs of the engines de- signed and built for the World's Fair launches. The cylinders are 6 and 12 inches in diameter b)- S inches stroke; cast in one piece, with the recei\-er, etc., enclosed inside of the lagging, which is of cherry, handsomel)' finished and held in place by brass bands. The vah-e cliamljers are set at right angles to the crank shaft, which greatly reduces the fore-and-aft .space of the engine — a very essential point in a small engine-room. This also brings the valve chambers close together, making a quick passage of steam from the high to the low-pressure cylinder, thus doing away with the long outside exhaust pipe connnon to most compound engines. The cylinders are sup- ported from the bed of the engine by cast-iron columns on the back side, forming the guides for crossheads, and on the front side by three steel posts, planed square in the center, to which are bolted the bearings for the rocker shafts operating the piston valves, also the bearings for rever.se lever and braces from po.st to frame. The crank .shaft is cut from solid steel forgings, with counterbalance fitted on the two inside cranks, which have notches in them for baring the engine over when cold. The crossheads, crank-pin boxes and all .small connec- tions are made of a high grade of phosphor-bronze, and the main bearings on the crank shaft are lined with Magnolia metal. The quadrant is attached to the reverse lever and made fa.-,t by a clamp on the center post, ,so that when the engine is in the go-ahead gear, the lever stands in an upright position and the "quadrant is entirely enclosed in the engine proper. As will be seen, the air and feed-pumps are fastened to the engine bed, and are operated from the crank .shal't by means of a worm and worm gear, which reduces the .speed of the pump one-fourth the revolution of the engine, reducing the friction and overconfing all noise made b>' the valves in all high-speed pumps. The thrust bearing is also connected to the engine bed Ijv two steel studs, and as the thrust collar is made fast to the shaft the adjustment is made by the two thru.st bars, which have faces lined with fJabbitt metal and held in place by double loeknnt on the two steel studs. These engines were de.-igned and built by Edward rf. Clark, Boston, Ma.ss. The Davis-Farrar Yacht Engine.

The pillow blocks ha\-e removable bushings, enabling the wear to be compensated for by shimming or removal at slight cost.

The method of oiling is shown in rear view, a brass pipe extending along the cj'linders, from which smaller pipes Ijranch, conve^•i^g oil to the journals, each being pro\-ided with a cock to regulate the supply-. The engines have been designed for hard duty under high steam pressure, and have repeatedly on all da\' runs turned a 42-inch wheel, 6 feet pitch, 31(1 re\-olutions per minute, without warm journals or pins. In two years' service on the x'acht Tallalusa, a set of these engines have never .-^hown a warm pin or journal under 185 pounds steam pressure. Great care is taken with the lialanciiig of the engines. The steam distribution, as well as the weight in counter- balances, being carefully decided after extended experiments with each size engine. The importance of steam distribution is now very .generally I'ecdgnized by builders of high-speed en.gines. The valve .gear has been designed with this especial object in \-iew ; its extreme simplicity will first attract the attention of the engineer ; in operation it can be compared with the Corliss only. The fast and .slow travel of the valve occurs at the desired points, and there is no perceptible difference in the events of induction, release or compression from full stroke to any point of cut-olT d(.iwn to zero. It is usually designed to cut-off at 'j or ? ,-; stroke as nmximum. Its construction can be understood from cuts, Fi.g. 1 showing the .gear in skeleton. The eccentric strap has attached to its top and bottom sides an arm or link, each 12 inches long, the upper link being pivoted at a point y inches from center of pin connecting it t(i the top of eccentric strap. This fixed point is supported Ijy a suitable stand bolted to the engine base. At its outer end is a ([uadrant, an arm of which extends downward and is connected to the lower liid-:. It will be seen that the vertical throw of the eccentric, operating the upper link or lever over its fixed point, carries its outer end, to which is attached the (juadrant vertically, a distance governed ])\- the throw of the eccentric and the position of the " fixed point" or fulcrum, a distance ecjual to the lap and lead of the valve. The lower link connects the li.iwer arm of the quadrant to the bottom of the eccentric strap. The horizontal throw of the eccentric imparts a "rocking move- ment" to the quadrant, and it is obvious that the position of the valve .stem on the quadrant regulates the port opening for steam ; when in the center, zero, there can be 110 port opening other than the lead, and as it is thrown toward either end more port opening is olifained. Its action can be seen in Figs. 2, 3 and 4, In Fi.g. 2 the engine is on the bottom center. The throw of the eccentric being down has raised the valve an an:ount equal to the lap and lead, and it is ready to take steam at the same time the full horizontal throw of the eccentiic (its (juiek tra\-el 1 is read)- to throw the lower arm of the quadrant to the right and rock its outer end up, giving the port opening with the quickest travel of the eccentric. Fi.g. 3 shows the port open, and it will be seen that the vertical throw of the eccentric beginning would tend to close the port, wdiile the horizontal throw rocks the lower arm of the quadrant further, and maintains the valve in its position. The one throw operating against tlie other, causes the valve to pause or slow up. In closin,g the steam port, in Fi.g. 4, it will be seen that the vertical throw of the eccentric is at its quickest point, while the horizontal throw is at its slowe.st and will have little effect in opposing it. Two years' .service has developed no weakness or faults,' and the steam di.stnlmtion given by it is all that could be desired, giving as it does a quick opening and closing of the valve with the slow travel at that point that allows^a free admission and exhau.st, and none of the objection- able features of the ordinary Stephenson link. These engines are built by the Davis-Farrar Company, of Erie, Pa. The Joy Valve Gear. The cut shows the ingenious arrangement whereby David Joy, of London, has avoided altogether the u.se of eccentrics. He obtains the motion irom the connecting-nid, and qualifies it bv a sliding Idock like Hackworth, or a suspension-rod like Manshall. The motion thus obtained is a very perfect one for a slide valve, as the two quick and two slow periods are just when re(juired. The amount of opening is equal at both ends (jf the \'alve, and earl>' cuts-off can be effected without exces- Jon's \',\i.\1.. ( ;|. \K sive leads and compressions or premature exhau.stings. This gear has been applied with great success to locomotives, where the saving of space for the eccentrics admits of longer crank pins and journals ; it has also been taken up by martne engineers. The chief fil)jections to this gear are that it comes in the way of the principal working parts, and makes them a little difScul't to get at when working, and also that a small amount of wear on tlie joints of the gear would cause a deflect in the valve motion, and produce a serious amount of rattle of the "-ear. HOWELL'S STEAM VESSELS AND MARINE ENGINES. 73 These, however, can be got over by making the pins substantial and all the joints adjustable. David Joy, of London, has recently designed an arrange- ri:ent of reversing gear for marine engines, by means of which link motion is done away with and yet the effect of linking up can be obtained, whilst reversal of the engine is under perfect control. This result is accomplished by putting a pair of hy- draulic cylinders in the eccentric sheave, and in this way can shift it to an equivalent of any position on the shaft, from full gear ahead to full gear astern, whilst the intermediate position naturally brings it concentric with the shaft, so that the valve has no motion at all. The Marshall Valve Gear. This arrangement of slide-valve gear, which has been fitted by R. & W. Hawthorne, Leslie & Co., Newcastle-on- Tyne, to a large number of marine engines, including those of several recent ships of the Royal Navy, is illu.'trated in Fig. 103. In this system only one eccentric is u.sed, the end of re\-ersing le\-er R, an}- desired degree of expansion can be obtained or the engines reversed as required. In this system there are few working parts, and the distrijjution of steam both for full power and for expansive working is satisfactors-. Richard vSennett. Marshall's valve gear is a modification of Hackwortli's, and differs from it in the method of getting the oblique motion of the rod-end. Fig. 6S shows the plan adopted by F. C. Marshall, of Newcastle-on-Tyne, and also illustrates general!}' what has been said of Hackwortli's. Here the eccentric-rod is hung, by means of a rod fnjm the end of a lever, on a reversing shaft in such a way that it moves on the arc of a circle inclined to the centre line. The motion is not quite so perfect as with the inclined sliding bar, and necessitates double ports to the bottom end of the slide valve in order to get as much opening to .steam there as at the top end ; but there is less friction, and, on the whole, it works mo.st satisfactorily. The pins require to be of good size, and they should all have adjustable brasses to provide for the large amount of wear which of necessity comes on them. A. E. Skaton. Fig. 103.

The engraving shows a vertical steeple compound engine with but a single valve to operate both cylinders. There is no receiver, the exhaust going direct to the low-pressure c>linder through the valve itself. The engine, as shown, !;as a high- pressure cj'linder iS inches diameter, and a low-pressure cylin- der 36 inches diameter, the steam chests on both cylinders con- necting with a conduit of sufficient area to equalize the steam pressure on both ends of the hollow piston valve, rendering it perfectly balanced, the difTerence of areas in the tail-rod and valve stem being so proportioned that the weight of the vah-e is balanced by the difference of pressure on the top and bottom heads. It will be seen that there is but one ^-alve for both cylin- ders, the ^'ah•e itself taking the place of a receiver. Tliis ar- rangement reduces the unavoidable loss in the receivers com- monly used, in the increase of volume and condensation in passing the steam from one cylinder to the other. The plan is the device of Hobart Canfield, of Morristown, N. J. In this system, the valve being jacketted by live steam at boiler pres- sure, any moisture due to the first expansion is reheated by the live steam as it passes through the valve from the high to the low-pressure cylinder, and tlie condensation is reduced \'erv materiallv. Cards taken from one of these engines witli an initial pressure of 100 pounds in the high-pressure cylinder, cutting off at 5,3 stroke, show 26 pounds initial in the low- pressure cylinder, thus proving that the increase in V(jlume be- tween the c)dinders is reduced to its lowest terms, for in this system the pressure is about double that which would be indi- cated if a common receiver were used. This system has been practically tested, and the in\'entor, Mr. Canfield, has several engines from 500 to i,5riO horse- power in service.

Bonner's Patent Compound Balance Valve. A very ingenious valve has Ijeen designed by John Bonner, Master Mechanic, of Tilnirnn, Cal. This valve simplifies the handling of compound engines in a marked degree, making it very economical in both water and fuel. The cut illustrates a steeple compound engine ecpiipped with this valve, which, as will l)e seen, dispenses with the steam chest and steam recei\'er.

In connection with a water-tube boiler, patented by the same inventor, stea:n is generated very quickly with a con- sumption of but little fuel. The dimensions of this engine and boiler are: High-pressure cjdinder, 2-^8 inches; low-pressure cylinder, 4^4 b^^ 414' inches ; height from base to top of high- pressure CN'linder, 27 inches. Weight of engine, 90 pounds. Boiler has 3 square feet of grate surface and a large heating surface. The boiler weighs, with casing, 350 pounds, and measures 20 by 24 b_v 34 inches. The United States Govern- ment license permits a pressure of 250 pounds, although iSo pounds is about the average used in running the launch. With this pressure, the 22 '_> -inch propeller wheel makes 350 revolutions per minute on a consumption of from 15 to 20 pounds of good steam coal per hour. The construction of these valves is very .simple, and there is nothing about them to get out of order. It is so perfectly balanced that b}' its use all the valve gearing, eccentrics and straps can be made one-third of the weight of an ordinary engine of the same horse-power. The engine frame and base are made of steel as light as possible, combined with strength. The Sullivan Tri|>le=Expansion Yacht Engine. The increasing interest now taken in steam yachting has necessitated a better class of machinery than heretofore. Speed is now of the first importance, though mo.st owners are par- ticular about the appearance of their engines and wi.sh them to be as attractive as possible. The illustration represents a triple- expansion engine built by John W. Sullivan, New York. The cylinders are all three in one casting so as to save weight, the back of columns which carry the guides for the cro.ssheads, are all cast hollow of steel and the bedplate is also of steel for the same reason. Piston valves are used throughout, driven by Bremme gear so that the engine is very open in appearance, easy of access and greatly .simplified. Light steel colunms .support the front of the cylinders. The crank shaft and eccentrics are forged steel in one piece, while the connecting and piston-rods, valve gear and all bolts and nuts are also steel. The connecting-rods are bored through the centre in order to further reduce the weight. The air and two feed-pumps are a single bronze casting, motion being obtained from the low- pressure engine through the medium of light steel levers and 76 HOWELL'S STliA?»I VESSELS AND MARINE ENGINES. links. The thrust bearing is arranged on the after end of the engine bed where it is under the immediate supervision of the engineer. The space occupied b^' these engines fore and aft is one-tliird less than is required for tlie ordinary st>de of con- ■^truction, while the entire engine can lie oiled and inspected troni the starting platform. On a recent trial of one of the small sizes (jf these engines some remarkable results were obtained. The diameters of the cylinders were 5, .S and 13 inches, respectively, with a common stroke of 8 inches. With a boiler pressure of 2rio pounds, the number of revolutions made was 400, which is equal to a piston speed of 533 feet. Calculated percentage of admission, small cylinder, 70; intermediate cylinder, 60; large cylinder, 7'j. Horse-po'>\'er estimated 3S, 39'_- and 40 ' j , respectively, or 118 horse-power altogether. The entire weight of engine, including air and two feed-pumps, is 2,480 pounds. The propeller was 38 inches diameter by 6 feet pitch, and the speed attained was over 17 miles per hour. The vacuum maintained was 26 inches, which is very remarkable considering the high number of revolutions, while the engines were absolutely noiseless and developed no tendency to heat or cause trouble in an}' way. On the score of economy these engines make a most satisfactory showing, furnishing a horse- power for 1. 6 1 pounds coal per hour, which is equivalent to less than one ton of coal for ten hours steaming, or a distance run of about 200 miles. Engines of the Yacht Neaira. These engines ( illustrated lj\- Fig. i 1 were designed and patented by T. Main, Arlington, N. J., and constructed by R. Wetherill & Co., of Chester, Pa. The Neaira is built of steel, and is no feet long on the water line, 20 feet beam, and 10 feet deep, with 7 feet 3 inches draught of water aft : mean draught, 5 feet 10 inches ; speed, 13.6 knots an hour. The engines are of the balanced compound type; the high- pressure cylinder is 15 inches diameter, and the low-pre.ssure is 28 inches diameter Ijy 16 inches stroke; the cylinders are placed at an angle of about 23 degrees apart, and the cranks are directly opposite, so that the working parts of the one engine very nearly Ijalance similar parts of the other. The pistons work in opposite directions, consequent!}' the pressure of one piston is nearh' balanced by that of the other through the crank, and the pressure on the shaft journals is reduced. This causes a great reduction of friction in p.issing the centers, and con- sequently increases the power. These engines require onlj- two journals, which makes a great reduction of length in a fore-and-aft direction, and which, in this vessel, allowed for an additional row of .staterooms athwartship, which was a very great advantage to the owner. The valve motion is taken from the connecting-rods, and pi-^ton x'ah'es are used on both cylinders, which are controlled fiv one starting handle for .starting, stopping, .going ahead, backing, or working expansively. And owing to the engines being at an angle to each other thev have no dead centers, l)ut can be controlled under all conditions. The surface condenser is located on one side of the engines, with nidependent air and circulating-pumps under it. The feed-pump is also independent. The thrust bearing is bolted to the bedplate, and accessible in the engine-room. In this t\pe of engines the journals require less wearing surface than usual, and tend to remain cool when running fast, owing to the work ,'iiTi,i,i\".\N's TRiPT.r;-I'",xi'ANSioN Y.-\cht Enoine. on them being light. It is believed that there is no type of engines before the public to-day so compact as these, or which admits of so much power being located in so small a space. vSteam is supplied at a pressure of 125 to 150 pounds by a Scotch type of boiler (illustrated by Fig. 2) with two corrugated furnaces 33 inches diameter; the boiler is 8 feet diameter by 10 feet long, has a steam drum and an air heater located at the base of the smoke.stack. T. Main's system of hot blast is fitted to the boiler. A fan blower, driven by a pair of balanced compound engines 3 ! c and 6 inches diameter by 4'j inches stroke, is used to draw air from over the boiler, and forcing it through the air heater into the closed furnaces ; 80 per cent, of this air goes under the grate, and 20 per cent, of it above, at a temperature of 220 degrees. This vessel has run several times from New York to New London, a dLstance of 1 10 statute miles, in .seven hours, consuming two tons of coal during the run. The engines have been run at a maximum speed of 1,80 revolutions, with 150 pounds steam, and indicated 348 hor.se-power! They have been u.sed during eight yachting sea.sons, very little has been done to them, and they are now in good condition. A modified plan of the blowing engines on this yacht is illustrated by Fig. 3, adapting them for u.se on small yachts or launches, for running dynamos, blowers, or for stationarv v.'ork.

It is claimed such a combination will i)roduce an indicated horse-power on one pound of coal per hour when properly carried out and worked. Fig. 4 represents the engines of the Neaira modified as balanced quadruple tandem engines, fitted with steam jackets on three cylinders, and .so arranged with movable stuffing boxes that the lower pistons, cylinder heads and valves can be removed without disturbing the upper cylinders, and all this will occupy no more space than an ordi- nary .single upright engine. Three Cylinder Compound Engines of Steamer Pleasure. The boat whose engines are illustrated on another page, is a wooden vessel built in 1894 ^Y F- W. Wheeler & Co., West Bay City, Mich., for the Belle Lsle and Wind.sor Ferry Com- pany. She is to run on the Detroit River, touching at Belle Isle, Windsor, and other sununer resorts. The distance be- tween stops being too short to olitain the full benefits of a triple- expansion engine, it was decided to adopt a three-cylinder compound engine, thereby retaining the smooth working of a triple-crank engine. Tlie high-presstire cylinder is 24 inches diameter, and the two low-pressure cylinders are 34 inches diameter each, with a common stroke of 24 inches. The high- pressure cylinder is placed in the center so as to equalize pressures and passages. Each cylinder is fitted with relief valve, and a 3-inch .starting valve is provided to admit live steam into both low-pres.sure cylinders. The engine is de- signed for a piston speed of 500 feet per minute. The ports in the high-pressure cylinder are 2'- inches wide and ly inches long, and both low-pressure cylinders have ports 3 inches wide and 26 inches long. The main steam pipe is 7 inches diameter, the receiver pipe is 8 inches diameter, and the exhaust pipes leading to condenser are each g'j inches diameter. The throttle valve is of the balanced cylindrical type, and fitted with suitable relief valve so as to work freely. All cylinders are fitted with valve-chest liners of hard, close-grained cast iron, with diagonal bridges and ports 2 inches wide The high- pressure vaU-e is i r inches diameter, fitted with solid ring so as to be easily renewed, and the low-pressure valves are each 15 inches diameter, fitted with self-.setting spring rings. The out- side lap on the high-pressure valve is i 3-16 inches on t(.)p, and I inch on bottom, and 3-16 inch inside lap on bottom ; the low- pressure valves have I 9-16 inches lap on top, and i^:-; inches on bottom, with an inside lap of 3-16 inch on bottom. All valves have a travel of 5 inches, and are worked directlv by the Stephen.son double bar link motion provided with adju.st- able cut-off arrangement. Steam is cutoff at 0.75 stroke in high-pressure cylinder, and 0.65 stroke in low-pressure cylin- ders when in full gear. All valve stems are of machinery .steel 2,^4 inches in diameter, and are guided by adjustable valve stem guides with brass bushings. The engine is provided with steam reversing .gear, having a cylinder 8 inches diameter and 12 inches stroke, operated by a differential valve motion under easy control of the engineer. The pi.stons are of cast iron 6 inches deep fitted with adjustable spring rings. The piston-rods are of machine .steel 4 inches diameter, secured to crossheads and pistons by tapered ends and nuts. The crossheads are of wrought iron, with gudgeons and .slippers forged on. The slippers are provided with brass gibs 10 inches wide and 14 inches deep. The connecting-rods are of wrought iron 6 feet between centers, having the upper end forked to suit the crosshead pins, which are 4 '4 inches diameter and 4 inches long. The upper ends are turned 3^4 inches diameter, and the lower ends 4.-^4. inches diameter. All bolts in connecting- rods are of .steel i -'4 inches diameter at the upper ends, and 2 '4 inches at the lower ends. The crank-pin brasses and all main journals are lined with Magnolia anti-friction metal in strips. The cylinders and valve chests have a magnesia covering, and are lagged with highly polished cherry. They are supported by six cast-iron columns, the port columns being provided with large bearing surfaces and water jackets for the slides. Through bolts are used wherever practical throughout the whole engine. The bedplate is of the box tj-pe cast in one piece, with six main journals, and raised feet for columns. All main journals are provided with cast-iron caps secured by two 2'_- inch bolts. The crank shaft is made of wrought iron of the built-up type, and is 9 inches diameter. The crank arms are 5)-< inches thick for the forward low-pressure, 6 inches for higli- pre.ssure, and 6'- inches for the after low-pressure, with a conunon width of i6'^4 inches at the pins, and 18 inches at the shaft. The cranks are placed 120 decrees apart with the forward lou'-pressure leading the high-pressure, and the after low- pressure following. The three thrust collars are forged on crank .shaft and are 15 ■•:■ inches diameter and 2'.^ inches thick. The thrust bearing is bolted to the bedplate and is of the horseshoe type, with four cast-iron columns with anti-friction metal facings adjustable by means of steel bolts and brass nuts. The collars are designed for a pressure of 50 pounds per square inch, and a line bearing 9 inches wide is ca.st on the thrust block to support the shaft, while a similar bearing supports the line shaft. The stern tube is of cast iron iS feet long, with an internal bearing at the forward end. The stern bearing is bolted to the stern post, and is of cast iron with a cap 20 inches long lined with lignum-vitse, and adjustable by means of a rod running through stern post. The line and propeller shafts are 9 inches diameter, and g^i inches diameter at the bearings. The propeller wheel is 10 feet diameter and 13 feet pitch ; it is of the cast-steel dovetail type, patented by the Dry Dock Iron Company, of Bay City, Mich. Steam is furnished by two cylindrical return tubular boilers 10 feet in diameter and 12 feet long, designed for a working pressure of 135 pounds per square inch. Each boiler has two furnaces, 40 inches diameter and 9 feet 3 inches long, and 152 3-incli tubes, giving a total grate surface of 7S square feet, and a total heating surface of 2,554 square feet. The boilers were built by \A'icks Bros., Saginaw, Mich. All pumps are independent and were supplied by Dean Bros., of Indianapolis, Ind. The air-pump is single acting, steam cylinder 12 inches diameter, water cylinder 16 inches diameter, and a stroke of 12 inches. The feed-pump is of the duplex, outside packed, plunger type, 10 by 6 by 12 inches. A suitable fire-pump, bilge-pump, and water-service pump for tanks are also provided. The exhaust steam from all pumps passes through a feed-water heater, 20 inches diameter with 52 I'/o- So HOWELL'S STEAM VESSELS AND MARINE ENGINES.

By this labor-saving de\'ice the ashes are forced overboard by water under pressure from the deck pump. The principal dimensions of the ves.sel are: Length over all, 140 feet; length on load water line, 127 feet 4 inches; breadth over guards, 5t feet 6 inches ; beam, moulded, 39 feet 7 inches ; beam on load water line, 36 feet ; depth, moulded, 14 feet 5 inches; draught aft, 12 feet ; draught forward, 9 feet. The hull is built of white oak of very heavy dimen.sions throughout, and shaped forward so as to enable her to easily break through the ice encountered during winter .-,er\-ice lie'tween the cities of Detroit and Windsor. The vessel has three decks, and is capable of accommodating 2,000 pa.s.sengers. The designs of hull and machinery were made by the builder's con.structing engineer, S. Anderson. Donegan «& Swift's Launch Engine. This engine is very light in weight, and simple in its work- ing parts and design. It is a single engine, with reversing horse-power. lever, operated on the .side.

These engines are built by Donegan tt vSwift, New York. Lumgair's Quadruple=Expansion Engine. David Lumgair, of West Bay City, Mich., has two patent^ on a quadruple-expansion condensing engine, which, it is claimed, is suitable for the heaviest marine work. The prin- ciples can also be applied to the triple-expansion engine for those who prefer lower steam. The working of this engine will readily be understood by examination of the accompanying illustration. Steam from the boiler enters the high-pressure valve chest through opening «, and enters the lower end of the cylinder on the top side of the valve, leaving the c^dinder through the bottom side of the valve. It then enters opening /', and passes through pipe b to the upper end of the valve chest, and enters the top end of the cylinder on the bottom side of the upper valve, lea-f ing the cylinder through the top side of this vah'e, where it enters pipe c, leading to the second inter- mediate pressure valve chest. The steam enters this cylinder through the bottom side of the valve, and leaves on the top side of the valve ; it then passes into the low-pressure valve chest, enters the valve on the top side, and exhausts through this valve into the condenser through opening e. The high-pressure, first mean pressure, and second mean pressure are piston valves ; the low-pressure valve is a slide valve. The spaces between the two pistons on each engine are connected to the condenser. A live steam pipe, v\dth valve connection, is placed under the valve on the first intermediate pressure. Donegan & Swift's Launch Engine. There being always a vacuum between the two pistons, the difference in area of the two cylinders, multiplied by the vacuum, will give, in the smaU engines shown, 4 honse-power to the first two cylinders, and 16 horse-power for the other two cylinders, and equals the power gained by the vacuum. It was found that by opening the live steam connection with the upper valve on the high-pressure end, the engine could be forced in ca,se of emergency. In trying it on a 12, 17 and 24-inch triple- expansion engine, 25 more turns a minute were made. The inventor, Mr. Lumgair, claims for the.se engines that they are easily handled and reverse well. They take up little room in the boat, there are only two sets of engines to look a'ter and the pistons are easy to get at. The fir.st co.st is low, and the fuel con.sumption is .small.

The motive power of the Cincinnati consists of two steeple compound engines, of which we give a perspective view. The.se engines were designed by H, S. Hayward, Superintend- ent of motive power, and H. Canfield, and constructed at the Pennsylvania Railroad Company's shops at Hoboken, N. J. The high-pressure cylinder of each engine is iS inches diameter; low-pressure cylinder, 36 inches diameter : stroke, 26 inches. A distinguishing feature of these engines is the balanced piston valve, which is the invention of Hobart Caiiiield, Master Mechanic in charge of the Pennsylvania Railroad shops at Hoboken. Fig. 3 shows this valve on a larger .scale, and its action will be readily understood. One valve is u.sed for both cylinders. When the pistons are at the iijiper end of the stroke, the valve occupies the position as shown in Fig. 3, allowing the steam from the lower part of the steam chest to pass through the upper port of the high-pressure cylinder as indicated by the arrows i ; while the exhaust steam from the high-pressure cylinder passes through the lower port, as indicated b>' the arrows 2, into the valve, which is cast hollow, and leads the .steam into the upper port of the low-pressure cylinder, as indicated by arrows 3 ; the exhaust from the low- pressure cylinder pa.sses through the lower port into the upper part of the chest, as indicated by arrows 4, from whence it flows through the exhaust pipes into the conden.ser. The advantage obtained with the u.se of this valve is that, during the passage of the steam from the high-pre.ssure to the low-pressuVe cylinder, condensation is reduced, and a comparatively high pressure is secured in the low-pressure cylinder. The weight of the valve .stem and tail-rod is such as to counterbalance the difference in pres.sure on the upper and lower ends of the valve.

In these engines the valves are actuated by a Joy gear, but they may be operated by any of the usual motions Ihe mam shafts are coupled between the two engines, so that m case of an accident to either engine or line of shafting, the}' can be disconnected and used independently. The shafts extend the entire length of the boat, with a four-bladed Fig, 3. — Can1'IEi,i>'s Bai,anck Vai,ve. sectional propeller wheel at each end ; these wheels are 8 feet 9 inches diameter, and 13 feet 6 inches pitch, and work together in either direction.

The air-pump is of the Knowles pattern, with lo-inch steam cylinder, i;-inch air- cylinder and 16-inch stroke. Steam is furni.shed b>- two return tubular fine boilers, 10 feet diameter, 16 inches long. Each boiler has two furnaces, 42 inches diameter, giving 49 square feet grate surface and 1,750 square feet heating surface, and is tested for a working pressure of 120 pounds. Out of the economical features in the design of a ferryboat for this service is that it is wasteful to have the boiler power equal to that of the engine, as over one-half of the boat's time is spent in the ferry slips. As the engines are idle so long, loss in the boiler pressure while crossing the river is desirable; so that with nearly uniform firing the boilers will not " blow off " while waiting in the ferrj- slips. On the test trips that w'ere made, a uniform boiler pressure of 97 pounds was maintained for two hours: the main engines made 92 revolutions per minute and dcA-eloped 720 indicated horse-power which gave a speed of 12.2,5 miles per hour. When the boat was stopped and the steam pressure allowed to reach 115 [)ouik1s, the engines showed 1,016 indicated horsepower and two miles were made in eight minutes, or at an average rate of 15 miles per hour; the steam i)ressure at the end of this run had fallen to 88 pounds. The tests showed that the boilers burned 15.85 pounds of coal jier square foot of grate per hour and "had evaporated 9.72 pounds of water to one pound of coal. There is, in addition to the main boilers, a donkey boiler 42 inches in diameter and 6 feet 9 niches in height ; a Craig circulating apparatus is fitted in connection with this boiler, by which a unitVirm temperature is maintained throughout the main boilers while steam is being raised. The principal dimensions of the hull are as follows : Length over guards, 206 feet ; length of hull, 200 feet; beam over guards, 65 feet; lieam of hidl, 46 feet ; depth from deck to keel, 17 feet; draft, 10 feet 10 inches- drsplacemeiit, S90 tons.

By close examination of the engraving, it will' be seen that the Coller patent valve motion to this engine is taken from the connecting-rod, which resnlts in a quicker opening of the valve than that of any other engine. These engines are built in sizes from 30 horse-power compound to 600 horse- power triple-expansion. See's Quadruple=Expansion Engine in Tug El Toro. The Morgan Line steel tug El Toro (the Bull), con- structed by the Newport News Shipbuilding and Dry Dock Company in 1891, from specifications of Horace See, New York, is one of the mo,st complete ve.'^.sels of her kind in the United States. The El Toro was designed principally as a fire boat, to be stationed at Pier 37, North River, and to tow the ships of the Morgan Line from that pier, where they go upon their arrival in port to discharge cargo, to Pier 25, North River, the lower berth, where the ves.sels are loaded. The dimensions of the El Toro are as follows : Length over all, 90 feet ; beam, moulded, 19 feet ; depth, 10 feet 9 inches. Her tonnage is 65.8 net and 130.16 gross. Tlie main engine is of the vertical surface condensing quadruple-expan- sion t>pe, with two cranks working at right angles to one another, two pistons being connected and arranged tandem to each other. The cylinders are 9^^, I3^j', 183-4' and 26 inches diameter, respectively, with 22 inches stroke of piston. Steam of iSo pounds pressure is employed. The lower c_\-liiiders are bolted together, and supported on one side by two columns, which are cast on the condenser, and on the other side by two wrought-irou columns fastened to the bedplate. The cast columns also form the guides, which are of the slipper slide variety, with water circulation through the go-ahead face. The front of the engine is open for examination of the journals. The upper cylinders are bolted together, each one being sup- ported on three columns secured to the lower cylinders. All of the cylinders are fitted with piston .slide valves, o]ierated l)y the See- Marshall vah'e gear, and rever.sed by steam gear from the upper platform. All of the main steam piston and valve- rods are fitted with the See metallic packing. The condenser is fitted with brass tubes and sheets. An independent cen- trifugal circulating-pump supplies the condensing water. The air-pump is driven from the crosshead, as are also the feed and bilge-pumps. There are also two Worthington independent vertical feed, fire and bilge-pumps, arranged either for feed, fire or bilge service. The circulating-pump is also provided with a bilge suction for pumping out the boat. A Wass extractor is furnished to remove grease, air, etc., from the feed-water. The propeller shaft is covered with brass at the water end, which revolves on a lignum-vitse bearing ; the wheel is a solid true screw of iron, 7 feet in diameter. The boiler is of steel and of the cylindrical return tubular type, fitted with two corrugated furnaces leading into one common com- bustion chamber. It is 9}^ feet diameter by 10I2 feet long, and was built by Hammond & Coon, Buffalo, N. Y.

Tlie valves are of the piston type. The cranks are at right angles, thus avoiding any "dead centres." Rever.sing is effected by means of an improved gear, consisting of one eccentric for each valve keyed upon a loose sleeve placed on forward end of shaft. Loose sleeve is rotated about on shalt in either direction by means of a pin engaging in a .spiral in .sleeve and straight spline in shaft, said pin being moved forward and aft on shaft by a .second sleeve operated by rack and pinion. A pas.s-over valve introduces live .steam into the low-pressure valve chest when it is desired. The engine is provided with a complete automatic oiling apparatus, whereby complete and stored away for winter. Great economy in fuel and ease of handling make it most desirable for small yachts, while its handsome appearance makes it an ornament to the 3acht. This size of engine, with 250 pounds .steam pressure and 600 revolutions, will develop 5ohor.se-power, and is suitable for boats from 40 to 50 feet long. These engines are built by Riley & Cowley, South Brooklyn, X. Y. This firm was called upon in 1891 to build a fast steam launch for the Yale Navy, .so-called, the .same being the Yale, College Boat Club. This launch is to follow the regattas, or races, between rival colleges, and must necessarily be fast and handy to keep up with the contestants. The committee tried other builders before Riley & Cowle3', but the ves.sels supplied were not accepted, as they did not come up to the requirements. From "Steam and the Marine Engine." — By John Yeo. all journals are uniformly lubricated with running at highest speed. Adjustments for taking up the lo.st motion on every working joint of the engine are also provided, and the bearing surfaces are of ample area. It will be remarked that the en- gine presents a very open front, enabling attendant to adjust and in.spect working parts at all times witli facility, and allow- ing of repairs to be made without pulling engine apart. One of the marked features of these engines is the entire absence of vibration, even at highest speeds. This is due to the care with which the reciprocating parts are balanced. The ports and passages are so proportioned that excessive .speeds are possible without undue frictional resistance to steam in passing through them. The engine, being free from pumps, delivers its full power to the propeller, while the pumps, being independent, may be adjusted to their work. It is self-contained and of ex- ceeding light weight, and may be readily lifted out of boat This firm had no difficulty in con.structing a launch to fill the bill, which was to make a boat capable of a mean velocity of 14 miles an hour for seven continuous hours. They did this, as stated, and ran a measured mile in slack water in 3 minutes 15 seconds, which is at the rate of 16^-2 miles an hour. The details of the launch are as given herewith : The hull is 53 feet long over all, 8 feet 6 inches beam, by 4 feet deep ; she is an open launch, having a cockpit fore and aft, with a car-top canopy over engine and boiler, and curtains to enclose the machinery. The engines are the Riley & Cowley triple-expansion type, 5, S and ly^ by S inches. The pi.ston valves are on the side, so as to economize space fore and aft. The valve motion consists of three gears ; one is keyed on the crank shaft, one on a three-throw crank .shaft (cranks coinci- dent with main crank shaft), and one large gear on a movable stud to raise the wheel above or below centre line, so as to give ss HOWELL'S STEAM VESSELS AND MARINE ENGINES. angular advance to valves for forward or back motion. The impro\'ed rever>ing .gear of this engine was suggested by Charles R. Cowley, sun of the senior member of the firm, and is the fir.st of the kind e\'er used. It marks a new departure in this branch of marine and mechanical engineering. No links or eccentrics are used, as the valves are driven by a small three- throw steel crank shaft, which derives its motiiju from the main crank .shaft by means of three cut-gear wheels. The intermediate wheel is ])ro\-ided \^ilh a sliding mechan- ism whereby it ma}* be moved along a line at right angles to a line connectinc; the two shafts. Paul's Patent Reversing Gear. With this gear the motion of the engine is rever.sed by shifting the eccentric centre across the shaft in a direction at right angles to the crank, from the ahead to the astern centre by the nteans shown in sketch. The shaft end is flattened, and the eccentric eye fitted to it with sufficient clearance at the sides to allow the necessary travel across the shaft. It is also bored out to fit a mandril, which, revolving with the shaft, is .shifted out or in by means of the ordinary reversing lever or wheel and screw gear. This mandril is fitted at the inner end with Pauls Patent Eccentric Single Valve Gear, eaual to Link Motion^ This motion gives the proper angular advance to the \ alves and determines the direction in which the engine will run. From the crank pins of the valve crank shaft are connecting- rods attached to the valve stems. The piston valves are fitted with rings and the .seats are bu.shed with steel. The cross- heads, valve stems, and piston-rods are also steel. The crank shaft boxes are of the best composition, and the propeller shaft is of Tobin bronze : it is 2)2 inches diameter, and the pro- peller itself is 36 inches diameter, by 5 feet pitch. The boiler is the Roberts water-tube t>-pe, having 16 square feet of grate surface. The condenser is copper, of the keel type, and all pipes are of copper and brass. Under the floor forward is a copper tank that contains 150 gallons fresh water. The certificate allows 250 pounds of steam. a steel pin, which projects through longitudinal slots in the shaft into diagonal slots in the eccentric. The pressure of this pin on the sides of the diagonal slots, as the mandril is moved out or in, causes the eccentric to move across the shaft. The eccentric is prevented moving endways on the shaft by a collar and washer. The valves of two cylinders working on cranks at right angles are actuated from one eccentric b>' the arrange- ment shown in dotted lines. The valve immediately over The eccentric is worked direct, while the other valve, which may be pilaced on centre line of cylinders, or out to front or back, is worked through weigh shaft and wipers, the motion for these being taken off the strap at right angles to the eye for the direct wrought valve. For three or more valves the motion is taken from the .strap at points corresponding to the position HOWELL'S STEAM \'ESSELS AND MARINE ENGINES. 89 of the cranks, with separate weigh shaft and wipers for each valve. The special point about this gear is that it has the prop- erties of variable cut-off and uniform lead as perfect as in the best link motion arrangement, the eccentric travel and valve opening being varied, while the lap and lead remain constant. Matthew Paul & Co., of Dumbarton, Scotland, are the owners of this patent gear. Compound Engines of the Hoboken Ferryboat Bremen. The Hoboken Ferry was the States to adopt the screw ferryboat. by a screw at each end of the hull, first ferry in the LTnited These boats are propelled one screw pushing and the illustrations. They were built by the North River Iron Works. The high-pressure C) linders are 20 inches diameter ; low- pressure cylinders, 36 inches diameter ; stroke, 28 inches. Each boat is provided with an independent air and circulating- pumping engine of the Blake .system, with compound .steam cylinders similar in general design to those furnished for the United States battleship Maine. They are of the following dimensions : High-pressure cylinder, 7 inches diameter ; low- pressure cylinder, 14 inches diameter ; stroke, 16 inches. These work two .single-acting vertical air-pumps 17)4 inches diameter, and 14 inches stroke. One double-acting horizontal circulating-water cylinder, 17 inches diameter, 16 inches stroke.

This principle was first applied here to the Bergen, whose engines are, however, of the triple- expansion type. A continuous shaft runs the entire length of the boat, and is driven by one engine. If the shafts were in two pieces, and not connected, each screw would, of course, have to be run by an independent engine. The Bremen and the Hamburg are sfster boats. Their hulls (steel) were built by T. S. Marvel & Co., Newburg, N. Y., and the machinery by the W. & A. Eletcher Company, Hoboken, N. J., in 1S92. The length of each over all is 222 feet; on water line, 218 feet 6 inches ; breadth over all, 62 feet ; breadth on water line, 35 feet ; draught, light, 10 feet 6 inches ; draught, loaded, about II feet; depth of hold, 17 feet. The total seating capacity in each boat will accommodate about 450 p;r.sons. Each boat has two compound engines, as shown in the formed in solid composition plates, instead of seats driven into cast iron. The piston and piston-rods are of composition, and the air and water cylinders are lined with composition. The extra amount of valve area permits the pumps to be run at a high rate of speed. The initial .steam pressure in the main engines will be 125 pounds, furnished from two horizontal boilers, 9 feet i inch in diameter, and 21 feet long. Each has two corrugated furnaces, 44 inches diameter. Total grate surface, 100 square feet. The boilers are tested to 250 pounds hydro.static pressure. The diameter of the crank shaft is g]i inches. The cranks in each engine are set opposite to each other, and when the engines are coupled, the center line of cranks in one engine will be perpen- dicular to that of the other, .so that the cranks practically stand at 90 degrees apart. The W. & A. Fletcher Company were the contractors for the entire boat complete. go HOW ELL'S STEAM VESSELS AXD MARINE EXGIXES. CoilPOUND E>'ii . HOWELL'S STKAM VESSELS AND MARINE ENGINES. Compound Oscii,i,aTing Engine of the Providence and StoninGTox I^ine Steamer Connecticut. —Built by Win. Cramp & Sons, Philadelphia, Pa. Oscillating Engines of the Connecticut. The Providence and Stonington Line, throngh the pensist- ency of the late Capt. David vS. Babcock, several years ago de- cided to try a compound o.scillating engine in its new freight steamer Nashua, and with that end in view contracted with the Morgan Iron "Works for the engine which now propels that boat, the hull of which, as well as that of the Connecticut, were built by Robert Palmer & vSon, Noank, Conn. After the engine was built, it was found that the modified Corliss valve gear with which it was fitted caused considerable trouble and anxiety, until Jerome Wheelock, of Worcester, Mass., put in the Wheelock gear, after which the engine worked like a clock. The Connecticut was designed by Geo. B. Mallory, New York, and her machinery was constructed by Wm. Cramp & Sons. The engine has a high-pressure cylinder 56^^: inches diameter and low-pres.sure cylinder 104 inches diameter, both being 11 feet .stroke, and both coupled directly to the main shaft. This shaft carries feathering paddle-wheels, which were originally 28 feet in diameter, and had 12 buckets 14 feet wide and 4I/2 feet deep. The steam pressure ordinarily carried is 120 pounds. Steam is furni.shed by .six gunboat boilers, each 12':: feet in diameter and 20 feet 3 inches long. These boilers are placed three together and are fired from two fire-rooms ; over each is located a centrifugal fan 6 feet diameter and 5 feet face, supply- ing 30,000 cubic feet of air per minute. The engines make about 25 revolutions per minute, and develop 4,500 to 5,000 hor.se-power ; the .speed which the boat can attain is 17 knots per hour. These engines are the largest oscillators ever built. The total weight of the engines and boilers, including the water in the latter, is about i,oco tons. The surface condenser has 12,000 square feet of tube surface. All the auxiliary engines work in connection with a separate surface condenser entirely independent of the main condenser. The direct-acting engine takes much less room than the beam engine, and also weighs considerably less than a beam engine of the same capacity. The Connecticut differs from her chief rival, the Pilgrim, in having a wooden instead of an iron hull. The design of her hull shows a bow line 171 feet long, or nearly half her length, then a short parallel body, and then stern lines sharper than those usually seen in other boats of this class. The principal dimen.sions are as follows : Length over all, 35S feet 6 inches; length on 11 feet load line, 345 feet; beam outside of hull planking, 48 feet 2 inches ; extreme width over guards, 87 feet ; depth of hold, 17 feet 3 inches ; extreme depth forward, 23 feet 6 inches ; extreme depth aft, 20 feet. 92 HOWELL'S STEAM VESSELS AND 1SL\RINE ENGINES.

This type is much more common in England than else- where. The term applies to a cylinder mounted on trunnions, oscillating on its axis to accommodate the lateral sweep of the crank, thus dispensing with a connecting-rod, crosshead and girders, the piston-rod being connected directly to the crank pin. At first there was a persistent effort to perform steam dis- tribution by means of, or through, the trunnions so as to dis- pense with valve gearing, thus reducing a piston steam engine to the most simple form it has ever attained, but these methods have failed in practice, and oscillating engines are now com- monly made with the usual slide or other valves like fixed engines. The object sought in the oscillating type of engines, aside from simplicity and cheapness, was the saving of room, or their compactness, a feature conspicuous in English practice, where oscillating engines are in a great many cases set directly beneath the paddle shafts of steamers, and have given excellent service. This method is not only applied to small boats, but to large steamers of the highest class plying in the English and Irish Channels. The shortening of the stroke of engines, and various mechanical devices for diminishing the distance between the piston and crank has rendered the oscillating arrangement unnecessary. The rapid movement of the cyl- inders on the inward stroke of the piston produces lateral strains on the piston-rod, gland and pistons that cause rapid wear and derangement, unless provided for by careful design, good material and the best of workmanship. In fact, but one firm in the world has attained complete success with o.scillating engines, that of Penn & Son, in England. — John Richards, in Industry, San Francisco, Cal. Compound Beam Engines of the Honam. The twin screw is displacnig the single .screw, and the paddle-wheel is giving place still more decidedly to the .screw propeller ; while in the method of operating the paddles the beam engine is destined soon to pass away. One finds several services which were formerly carried on by paddle steamers having beam engines now conducted b\' screw steamers. The Bergen, Bremen and Hamburgh of the Hoboken ferry are cases in point, while several paddle steamers have now been fitted with other types of engines than that of which the walking beam was such an attractive feature. It is true, it required marvelously little attention : but it was far from economical. It can serve no purpose to sing a requiem — many of our American friends might claim that it is yet too soon for that. Certainly, in this country the beam engine belongs to the pa.st. It never gained any distinct hold on British favor, although admired by Scott Russell, but several engines of the type have been made in this country for service in foreign waters, and a record of modern engineering practice would not be complete without a reproduction typical of the British design. A. & J. Inglis, of Glasgow, some years ago made probably the most successful engines of this class, and one is illustrated herewith. These we should have been glad to describe long ago ; but characteristic modesty on the part of Messrs. Inglis suggested excuses as frequently as we urged the claims of our readers. The present time, however, is not inopportune, since we may be said to be in the transition stage. vSoon the triple-expansion direct-acting engine will be exten- sively adopted for paddle steamers, as it already is for screws. It is not difficult to trace the evolution of the beam engine as applied to the propulsion of paddle steamers. The great difficulty in paddle engines was to .get a sufficient length of stroke of piston, while keeping the engine low in the ship, and minimizing the length of space required. It was soon recog- nized by Watt, and some American engineers, that the most natural and possibly most picturesque arrangement was to adopt the simple old-fashioned beam used by Newcomen for the colliery pumps and land engines. While American engi- neers adopted this system, Robert Napier, Watt, Maudsley, and Fawcett continued to use the side-lever engine, the first named bringing it to its perfect stage in the Persia and Scotia. This side lever may be termed the English form of the beam marine engine. Here it was considered undesirable to ob.struct the deck with the walking beam, while the adoption of the side lever enables the engineer to choo.se any proportion of .stroke and any size of paddle-weel that would best serve the purposes of the ship. American engineers have continued to use the beam engine, although, as we have indicated, there are evidences which encourage the belief that it will be superseded. Messrs. Inglis were the only firm in this countrj' which largely adopted the system, and the engines of the Honam, which we illustrate, are a typical design. One of the largest beam engiues constructed, however, was for the Puritan of the Fall River Line. The Inglis beam engine indicates several departures in the details when compared witlr the American engine of that day, and was more strongly built. The gallows frame, which supports the main center of beam, instead of being of wood, as was the usual practice in the United States, was of steel plates and angles, and of box section. It was secured to massive box keelsons on the floor of the ship. This style of framing had not then been adopted b}- an}' other firm, and it gave great satisfaction. The wooden frame used in the American engine "wobbled," and allowance had to be made for this in the clearance between the piston and cylinder ends, 5 inches being not uncommon. It is easy, therefore, to understand that there was considerable waste of steam and con,sequent loss of efficiency. The steel frame — which, by the wa3', is adopted in America — is perfectly rigid, and only the ordinary clearance is necessary. The Honam's engines were on the compound principle, and in this respect aLso were a departure. The cylinders, as shown on the front elevation, were inclined towards each other at the head, admitting of the piston-rods beiiig connected to the one point on the forward end of the beam. This secured a perfectly balanced motion. In the engines of the Puritan, already referred to, the cylinders are nearly vertical, and are connected at two points to the walking beam. The great difference in the size of the two engines — the Puritan's indicate 7500 and the Honam's only 2goo — militate against any reliable compari.-on of results, more especially as the former is worked under forced draught with Sturtevant fans, and has two superheaters utilizing the waste gases before they pass into the smokestack. It may be noted, however, that the indicated horse-power in the Puritan is at the rate of about 9 per square foot of grate area, while the power was i indicated horse-power to 3J2' square feet of heating surface; in the Honam the results were 9.7 indicated horse- power to I square foot of grate area, and i indicated horse- 'H HOWELL'S STEAM \-ESSELS AND MARINE ENGINES. power to 2.73 square feet of heatiug surface. The relative coal consumption r&sults would be interesting, but they are not given in the case of the Puritan. In the Inglis boats, fuel economy has alwa^-s been a marked feature. The high-pressure cylinder of the Honam's engines is 40 inches in diameter, with a stroke of 10 feet, while the low-pres- sure cylinder is 72 inches in diameter, with a stroke of 9 feet ID inches, the difference in stroke being due to the inclination of the cylinders. Double-beat steam and exhaust valves are provided, while the high-pressure cylinder is fitted with ex- pansion valves. The surface condenser is placed alongside the cylinders, as shown in the forward elevation, while the pumps are worked by a rod from the walking beam, as shown in the front elevation. The cooling surface is 5395 square feet. The walking beam, which is constructed in the same waj' as is u.sually adopted in American vessels, with cast-iron center and forged steel strap, is 23 feet in length, 11 feet deep, and weighs 14 tons. The secti(m of beam strap is 7 inches by 9 inches, and the main center is 14 inches in diameter in the main bearings. The piston-rod is 5 -=4 inches in diameter in the ca^e of of the high-pre.ssure, and 7 inches in that of the low-pressure engine, and of steel, while the connecting-rod is 23 feet long from center to center, and 13 inches in diameter. The crank shaft is 17' J inches in diameter. The paddle-wheels ha\'e feather- ing floats, and are entirely of steel. They are 21 feet in diameter, and the floats are 15 feet by 4 feet. These latter measurements are very unusual, and it would certainly be ver3' interesting to know if the builders of some of the recent fast paddle steamers have gone so far as to reduce the diameter of their wheels to 2.1 times the stroke, or to increase the float area to 60 square feet. Steam is supplied from three double-ended boilers placed athwartships and fired from the wings. These boilers are 14 feet in diameter and 14 feet long, and have in all 18 furnaces. The grate area is 297 square feet, and the heating surface 7939 square feet. They work at a pressure of 75 pounds, and at 33 revolutions the engines developed 2900 indicated horse-power. The steamer, which, with the engines working at this power, attained a speed of 16}^ knots, is 270 feet long, the breadth, moulded, being 38 feet, and the extreme breadth 72 feet 6 inches, the depth, moulded, 13 feet 3 inches, and the extreme 30 feet. The tonnage is 2800 tons. — London Engineering . Stevenson Taylor, Vice-President and General Superin- tendent of the North River Iron Works, Hoboken, N. J., wrote to the editor of Engineering, under date of September 12, 1893, as follows : Sir : — We are verj' much interested in your article " Beam Engines for Paddle Steamers" (issue of September i, 1S93), giving an account of the engine of the .steamer Honam, as we were when you before published (November 9, iS88j a descrip- tion of this .same .steamer. There are a few inaccuracies to wliich, in justice to our old friend, the beam engine, we must call your attention, and we believe you will be glad to correct them. I. The wooden frames of the American beam engines never "wobbled" to the extent that "allowance had to be made for this in clearance Isetween the pistons and cylinder ends;" and so far from "5-inch (clearance) being not uncom- mon," we must saj- that in our experience of over 40 years (dur- ing which time we have built and repaired hundreds of these engines; we have not seen one engine with 5-inch clearance ; i inch at each end being the usual design for the largest of them. If there ever was a beam engine with 5-inch clearance at each end or at both ends, it was because of an egregious blunder and not from necessity. 2. You refer in a complimentary manner to the iron frame and keelsons of the steamer Honam, parenthetic- ally remarking, " which, by the way, is now being adopted in America." We have a number of boats on our list, as well as those built by others, built before the Honam, which have iron or steel engine frames and keelsons, and some of these boats have wooden hulls. 3. The Puritan has not forced draught. The blowers mentioned only ventilate the fire-room, which is so open that no extra air pressure is possible. No exact test for deter- mining the economy of the Puritan engine has been made, but on the Citv of Fall River (a boat about the dimen.sions of the Honam) , belonging to the same line, and having the same style of engine as the Puritan, careful tests were made in 1883 (.see Journal of the Franklin Institute, July, 1SS4). These tests showed an average consumption of 2.04 pounds anthracite coal per hour per horse-power, and we have reason to believe that all of the engines built since, of the same st>de, perform just as well. The City of Fall River, by the way, has a wooden hull, with a wooden engine frame and keelsons, and both cylinders have a design clearance of i inch only. The engine frame does not " wobble." Of course, there is no use in these days advancing the advantages of the American beam engine. The tide is setting in other directions, but they ha\'e been, and still are, extremelv .serviceable,' and, considered all round, are eco- nomical for work performed. W. & A. Fletchrr Company. S.

Their special features are that the moving weights are in equilibrium, the pumps are worked direct from the beam, and the strains are more direct than in other engines. P'or the.se and other reasons they are more durable. Their use on ferryboats in this country arises mainly from the fact that the machinery, as a whole, is set on its edge, so to speak, the main working parts above the deck, and the space occupied, a long, narrow strip fore and aft, does not inter- fere with the deck traffic and loads. It is true, the engine space extends up through the cabin and above the roof, but this is not a great encumbrance. There is also the reason for ferry service that beam engines fitted with balance puppet valves as made at this day are ea.sy to ' 'handle ' ' and keep off the centers, because in equilibrium. For stationary purposes there are the objections of greater first cost, larger proportions because of slower speed, larger space occupied, but, notwithstanding this, one of the finest plants for duty in cotton mills has just been constructed in Eng- land on the beam system, and the most complete pair of wind- ing engines ever made on this coast are at this time (1S95) under construction at the Union Iron Works in San Francisco. —John Richards, in Indttslry, San Franci.sco, Cal.

Hence, the first thing to be done in setting beam engine valves is to set and to hold the rock shaft at the center of its motion, which is when the lifting-rods are down, the valves seated, and the lifting-toes adjusted the right distance from the rock shaft, and .straight with each other, so that the ends of both wipers will be the same distance from their respective toes. Next put the main crank on the center, and turn the throw of the eccentric directly in line towards the center of the eccentric- hook pin ; then make a fine center-punch mark on the edge of toe pin, and one on the edge of the hook .strap, and set a pair of compasses corresponding to the distance between those marks, and measure it. Add to that distance half the throw of the eccentric ; reset the compasses to that length, and move the eccentric until the eccentric punch marks and compasses again correspond, and adju.st the length of eccentric-rod so that the hook will just engage the eccentric-hook pin while the eccentric is held at that position ; then slack up the rock shaft so that y6 HOWELL'S STEAM VESSELS AND MARINE ENGINES.

To prove the accurac>' of adjustment, turn the main crank to its opposite center, and if there is a difference in the lead. either lengthen or shorten the eccentric-rod to make up half the difference, and turn the eccentric to make the other half, fasten the eccentric on the shaft, and the \-alves will be right. There can be no general rule gi\-en as to how the eccentrics sliould l)e placed in relation to the crank, as that depends on the relative arrangement of the lifters, valves, wipers, and rock- shaft arms. — The Eii;^ince>\ New York. HOWElX'vS STEAM VESSELS AND MARINE ENGINES. 97 The riorris Compound flarine Engine. This engine is built by the Morris Machine Works, Bald- winsville, N. Y. The engraving is of a 5 by 10 by 6-inch engine. The cylinders are cast .separately and bolted together with a receiver between them. The high-pres.sure cylinder has a balanced valve of the same type as that used in the Straight Line engine. The valve on the low-pressure cylinder is a com- mon D-valve. The cranks are arranged at an angle of 90 degrees to each other. All working parts, such as piston-rod, crosshead, connecting-rod, crank .shaft and link motion, are made of steel. The cylinders are supported by cast-iron columns behind and poli.shed steel rods in front, giving full view of all the working parts. Oil reservoirs are fitted on the Ijack side of the engine, and by pipes leading from these reservoirs the crosshead guide, crank pin, and crosshead pin are auto- matically oiled. One of the.se engines, during a recent trial, ran continuou.sly at 450 revolutions per minute, showing no tendency to heat. The steeple and the fore-and-aft compound engines are both built with a view to having a strong and substantial engine, at the same time having a fairly light design and an engine in w'hich every part can be easily seen in operation and readil}' got at. All the bearings are made to take up, except some of the smaller sizes in the link motion, where small bronze bushings are forced in, which can, when the bearings are worn, be driven out and replaced by new ones. The small vertical engine shown in the cut is built by the Morris Machine Works, Baldwinsville, N. Y. The engine is made in eight sizes, the smallest being 5 bj' 5. It will be noticed that the engine contains several features not found in any other, the principal one being the frame, which should at once commend itself to users of .small vertical engines. Free accessibility to all parts of the engine can be had at all times. These engines were designed for hard and continuous service, and are fitted in the best possible manner. The reciprocative parts are nicely counterbalanced, which will permit of high speed without vibration. Compound Engine of Steam Yacht Dream. The machinery that drives the fastest steam vessel ever built in Bridgeport, Conn., is the .subject of this sketch. This boat is the steam yacht Dream, designed for H. M. Hilhs, co- proprietor of the Evening Post of that city. The vessel is 60 feet long over all, 12 feet beam, 5 feet deep, and draws 20 inches forward and 3 feet 4 inches aft. The power required is supplied by a Herreshoff water-tube boiler. A Worthington double- acting vacuum pump controls a keel condenser consisting of 48 feet of 3-inch pipe. The engine, as shown in the prospective view, is a fore-and-aft compound, designed and built by the Coulter & McKenzie Machine Co., of Bridgeport, Conn. It is capable of furnishing 75 horse-power, and turns a 3-foot screw of 4 feet 7 inches pitch 250 turns per minute with 100 pounds of steam. The high-pressure cylinder is 6 inches in diameter, the low-pressure 12 inches and the stroke 9 inches. Both cylinders are cast in one piece. The exhaust from the high- pressure cylinder passes around that cylinder and into the low- pressure valve, thus making a receiver and jacket in one and permitting the passage of steam to the low-pressure cylinder without piping. The pistons are fitted with a .sectional Dunbar packing, consisting of a solid center, or "bull" ring, on each side of which is fitted an L-shaped ring and a square ring, with good results. These rings are cut in three or four .seg- ments, as may be desired, and are adju.sted so as to break joints. The rings are pressed against the walls of the cylinder by means of round wire springs of a diameter equal to the inside width of the rings. This construction insures even and suffi- cient pressure of the rings against the cylinder. The valves are of the balanced piston type, made up of a center and two end pieces held together by the valve stem and fitted with a steam-tight ring on each end. The live steam enters on the top of the valve, passes through the center and enters the cylinder from each end, the exhaust steam pas.sing around the center, as will be understood. The vah'cs are operated by Stephen.son link motion, the connections of which have every adjustment. The link blocks are bronze bushed, with a hard- ened and ground steel bush working on a hardened steel pin. The links are made in halves and bolted together. The cyl- inders are supported upon six steel columns, which are securely- fastened to a substantial cast-iron bed piece, making a frame which permits ready access to every part of the engine for repairs or adjustment. The Dream is a wooden vessel, built by Geo. W Ma.sters, Bridgeport, Conn., in 1893. Referring to the illustration of sectional plan of cylinders : The exhaust from the high-pres- sure c},'Hnder passes around that cylinder and into the low-pres- sure valve, thus making a receiver and jacket in one, and per- mitting the passage of steam to the low-pressure cylinder without piping. Quadruple=Expansion Engines of the Steamship Kensington. The International Navigation Company, of Philadelphia, Pa., had two large steel twin-screw .steamers built in 1S94 on the other side of the Atlantic — the Kensington, by James & George Thompson, of Clydebank, Glasgow, and the Southwark, by Wm. Denny & Bros., of Dumbarton, Scotland. The vessels are sister .ships. The engines are of the quadruple- expansion t3'pe, direct acting and surface condensing. The four cylinders each work a separate crank, and they are so arranged as to produce the minimum of vibration, the parts being so disposed as to be practically balanced without the use of counterweights. The order of the C3'linders from the forward end is high-pressure, second intermediate, first intermediate, low-pressure. The sequence of turning is high-pressure, low- pressure, second intermediate, finst intermediate. Cranks are at right angles to each other. Diameters of cylinders are as follows: High-pres.sure, 25^2 inches; first intermediate, 37)2 inches; second intermediate, 521-!^ inches; low-pressure, 74 inches, with a common stroke of 4 feet 6 inches. The high- pressure and two intermediate-pressure cylinders are each fitted with piston valves, and the low-pressure has a double-ported flat valve. All valves are worked b^- a single eccentric radial valve gear. It is operated b^- a single eccentric through a quadrant rocking on trunnions. The reversing is obtained by moving the sliding block attached to the valve spindle from one end of the quadrant to the other. The lap and lead is secured by a separate lever worked from the crosshead of the y8 H(n\']':iX'S STHAM X'ESSELS AND MARIXU KNGINHS.

The condensing water to each condenser is circulated by a large centrifugal pump driven by an independent engine. The air- pumps are driven by a le\-er working from the crosshead of a low-pre.ssure engine in the usual way. There is also fitted a large evaporator to produce the neces.sary fresh \\-ater from sea water to make up the feed, and to avoid the use of salt water in the boilers. A large feed heater and filtering arrangements are provided. An auxiliary condenser has, in addition, been fitted on board, with a separate circulating-pump, so that all of the auxiliary machinery- in the shi]i is worked separately from the propelling engines. An installation of Worthington pumps has been fitted on board. There are three boilers in the ship, constructed of steel, and adapted for a working pressure of 200 pounds to the square inch. Two of the boilers are double-ended, and are 15 feet 9 inches in diameter by 21 feet 5 inches long, while the single-ended boiler is of the .same diameter, but 11 feet 3 inches long.

The fans are 7 feet 6 inches in diameter, and are dri^-en direct by Sturtevant engines running under ordinary conditions at a .speed of 370 revolutions. The fans induce a draught through the furnaces, the air ha\-ing previou.sly been heated b}- pas.siug through tubes placed in the way of the waste gases from the furnaces. The inlet of air to the furnaces is through tubes placed in a casing o\-er the boiler, thence down a passage in front of the smoke box at the end of the boilers, and into the furnaces. The gases from the furnace, after passing through the boiler, play around the tubes forming the air inlet, and sub- sequently pass into the funnel at the base of which are the five fans inducing draught through the passages thus briefly indicated.

QUADRUPLE EXPANSION. 'KINGDON" PATENT ENGINE, FOR STEAM LAUNCHES. Constructed by vSimpson, Stricklanrl & Co., Dartmouth, South Devon, Englanfl. The Kingdon Patent Engine for Steam Launches. In these engine.s only one valve is needed to regulate the admission and emission of steam in the cylinders, ^^'hich are both double acting, consequently there are no more moving parts than in a single cylinder engine. The grade of expansion is directly proportioned to the area of the cylinders, and there is far less loss of pressure between them than is the case in most compound engines, owing to the .shortness of the pa.s,sages, and owing also to the fact that the temperature of the steam is maintained during its pas.sage through the valve by the live steam with which it is surrounded. The steam is carried throughout about nine-tenths of the stroke in all cylinders, and consequently the effort on the crank .shaft is very uniform. Both pistons being on the same piston rod, the strains on the crank .shaft, due to an unequal amount of work being done in the two cylinders at different portions of the stroke, are entirely done away with. These engines are constructed by Simpson, Strickland & Co., Dartmouth, South De^'on, England. Haug's Compound Marine Engine. In the accompanying cut, Fig. i shows a compound marine engine in which the pistons travel in opposite directions, the cranks being set at i8o degrees. The principal noveltj' in the design is the piston valve, which admits steam to the high- pre.ssure cylinder, then exhausts it into the low-pre.ssure cylinder, and finally into the atmosphere or condenser. The distribution of the steam by means of this valve is clearly indi- cated in Fig. 2, which shows a sectional elevation, a sectional plan, and a plan of the cylinders and valve. This figure also ser^'es to show the compactness with which the cj'linders and \-alve may be arranged, the valve being operated by a radial valve gear. A quadruple-expansion engine can be arranged on this principle, one set of cranks being placed at 90 degrees with the other set, as shown in Fig. 3, thereby securing a nearly perfect balance of working parts with great uniformity' of motion, and comparative simplicity. Charles Ward, of Charleston, W. Va., put a small engine of the type shown in Fig. i into the steam launch Mascot, built by him for the War Department, Engineer Corps. The hull, which is constructed of steel, is 61 feet long, 8 feet i inch beam, 3 feet 4 inches deep, drawing 7 inches forward and 14 inches aft. The engine has cylinders 6'^ and 13 inches in diameter, 8 inches stroke. During the trial the engine ran at the rate of 540 revolutions per minute, driving the boat 13 ^''3 miles per hour.

On April 11, ICS95, the Lighthouse Board, \\'ashington, D. C, opened bids for another of the high-class, electrically- hghted light-ships that have of late been introduced into the service. The illustration gives an idea of what the boat is like. This ve.s.sel is of compo.site construction, 112 feet on the water line, 28 feet 6 inches moulded breadth, and 13 feet depth of hold. The frame is of steel with steel-plate keel, steel bilge strake and steel sheer strake. Wood planking is used from the keel up to the sheer line at the main deck, and from that point up to the spar deck steel plate is used. The frames, floors, keelsons, stringers, beams, shear strake, bilge strake, strapping, keel plate, etc., are of steel; stem, stern- post, rudderpost, rudder, false keel, .shoe, .sheathing and grip on stern, bilge keels are of white oak ; keel, planking and deadwood of long-leaf Georgia or Florida pine. Fastenings in plank, keel and deadwood are of galvanized iron ; in the wood sheathing, composition spikes. The metal sheathing is 26, 28 and 30-ounce metal, double punched. The propelling engine, which will, of cour.se, be of use only in moving the vessel to and from her station or for handling her in case of accident that might remove her from her moorings, is about 350 hor.se- power, and of the vertical inverted surface condensing type, with a single cylinder 20 inches diameter and 22 inches stroke of piston. There are two main boilers of 300 hor.se-power each and two auxiliary of about 40 hor.se-power each. The main boilers, of the Watkin & Dixon type, the .same as those built by Heipershau.sen Bros. , New York, for several harbor tugs, are not more than 14 feet long, 8 feet wide and 8 feet 6 inches high from under side of furnace leg to top of shell, the shell S feet diameter.

The piston ^•alves have self-setting spring rings. Liners are fitted to the steam chests of the high-pressure and intermediate pres- sure cylinders, and the low-pressure steam chest has a false seat or liner for the .slide valve to work on. All valves have 4-inch travel and are worked direct by the regular Steven,son double-bar link. The valve stems of the high-pressure and intermediate pressure valves are i-'s inches diameter, and for the low-pressure i -'4 inches. They are made of steel and work in guides fitted with brass bushings. The eccentrics are of cast- iron 2 inches wide for the high-pressure, and 2 '4 inches wide for the intermediate j^re.ssure and low-pre.ssure cylinders, \vith ca.st-iron straps. The high-pre.ssure eccentrics are fitted to the end of the shaft, which is turned down to 2 inches diameter to receive them, thereby allowing the use of eccentrics of much .smaller diameter than tho.se of the other cylinders. The engine is supplied with steam reversing gear having a cylinder 5 inches diameter, 10 inches .stroke, and fitted with gag for adjusting the cut-off ; all are under easy control of the engineer.

Her dimensions are as follows ; Length over all, 85 feet ; load water line, 74 feet 9 inches ; beam, 13 feet 6 inches ; draft, 4 feet 6 inches. The keel, stern and stem post are of white oak, the deadwoods are of oak and yellow pine, timbers of selected white oak, .steam-bent : the floors or heel straps of be.st white oak, and planking of selected yellow pine. She is copper-fastened and riveted. The machinery con.si.'-ts of two triple-expansion engines, and a Seabury patent safety water-tube boiler. The galley is forward of the engine-room. The yacht was built in 1S93 for Caleb G. Evans, New York. After the iron steam yacht Alva ( built by Harlan & Hol- lingsworth Compan>-, of Wilmington, Del.) was sunk off the Massachusetts coast by the Metropolitan Line steamship H. F. Dimock, it was decided by her owner, W K. Vander- bilt, ot New Y'ork, to have a large twin-screw yacht built in England, from plans of St. Claire Byrne, of Liverpool, by Laird Bros., of Birkenhead, England. The Valiant is of the following principal dimensions : Length over all, 331 feet ; on load line, 293 feet ; beam, 39 feet ; depth, 25 feet 3 inches ; tonnage, 2,184; yacht measurement, 1,823 gross register; double bottom for water ballast purposes, 180 tons ; for fresh water, 30 tons, and the fresh water tank capacity is 50 tons. The deck houses, about 175 feet in length, and the bulwarks are of steel, but the whole paneled in teak. The engines are twin- triple compound. The cylinders are 23, 36 and 55 inches by 3 feet stroke ; boilers, two double end and a single end. fifteen furnaces in all ; 160 pounds pressure. At a trial in Liverpool Bay under natural draught, a speed of upwards of 15 '4 knots was established. This may be assumed to be the ordinary sea-going speed. Under forced draught and full power she ran for upwards of .six hours, and the mean revolutions being 145 per minute; 170 knots was covered in 10 hours and 50 min- utes, giving an average of 15.7 knots. On the measured mile, under forced draught, the mean two runs gave upwards of 17 knots, while the mean of the whole series was a fraction below. Weather squally and strong breeze, but the result very .satisfactory, as she had 700 tons of coal and stores on board.

The designer savs ' In preparing the plans of the Marietta, the principal ends ni view were good accommoda- tion and economical maintenance of a rea.sonable high speed for a cruising craft. The yacht is 142 feet 6 inches over all, 118 feet load" water hue, 16 feet beam, S feet 11 niches depth of hold, and 6 feet and 6 inches draught. The hull is of mild steel, the keel being 5 ' .. inches by i ' y. inches ; frames 2 inches by 2'inches, 3 pounds per foot ; floors 10 inches deep and from 3-16 to '4 inch in thickness ; plating from 3-16 inch to 5-16 inch thick. The bulkheads are three in number, a collision bulkliead forward and one at each end of engine space. The deck is flush, broken only by a low trunk over the owner's stateroom. The deck hou.se is 18 feet long, .serving as a social hall and dining-room, a dumb waiter leading to the galley below. The crew is berthed in the bow, then conies the cap- tain's room, galley and engine space. Abaft this there are four staterooms so arranged with a folding bulkhead between them that the\- may be thrown into one large room the full width of the yacht. The saloon is 15 feet long, furnished in the usual wa\- for da}- use, but with folding berths and cur- tains by whicli it can be divided into four separate rooms. Abaft of the saloon is the companion, with toilet-room to port, and a .stateroom to starboard, while abaft all is the owner's stateroom, 10 feet long and extending full width of yacht, the low trunk .giving ample li.ght and head room and superior ven- tilation The toilet-room is fitted with bath-tub, plumbed for hot and cold, fre.sh as well as .salt water. The yacht is lighted by electricity. The engine is triple-expansion, the diameter f)f cylinders being 12 inches, 18 inches and two 20 inches, \vith a uniform piston stroke of 15 inches. The bed- ulate is of cast steel. The cylinders are supported by eight i '3- inch steel columns, well connected and braced diagonall}'. All the moving parts are of steel, as light as due regard for strength as well as clurability will permit. The bearings and pins are large so as to run perfectly cool under all conditions. The valve motion is taken from a parallel shaft, geared to main crank shaft, and the reversing is effected by means of a sleeve on a parallel shaft, one end with a straight slot working on a feather in one of the gear wheels, and the other end having a spiral slot working on a feather on parallel shaft. By moving this sleeve in and out the necessary angular advance is obtained for operating the valves. The latter are all piston valves, fitted with packing rings to make them tight. The condenser has a copper shell to save weight, and has 482.^ s-inch tubes 5 feet long. Air and circulating-pumps are of standard make. The propeller is four-bladed, 4 feet 9 inches in diameter, of ca.st iron. The engine is carefully balanced and will be entirelv free HOWKIX'S STKAM VI'SSICLS AND MARINE l^NCINKS. t r I W. K.

The motive power is a SCO horse-power triple-expansion engine, with cylinders ii^-, 18, 30 inches by 16 inches stroke, all the cylinders being fitted with piston valves worked by a radial valve gear, each valve having an independent cut-off and the whole reversed by steam. The cylinders set on cast-iron columns with steel posts in front, giving a very open arrangement and easy of access to all parts of engine. The cast-iron columns carry the slides, which are cast with circulating passages for water. Cro.s.sheads are forged .solid with the piston-rods. Cranks set at 120 degrees and are "built up." Pins are 534 inches diameter by 6 inches long. Shaft, forged steel, 6 inches diameter, covered with brass. Wheel, 6 feet diameter, 9 feet 6 inches pitch.

Grate surface, 47'- square feet. Shell is i4-inch Spang steel, butt and strap ri\-eted. Working pressure 165 pounds. Cruising ( for which the boat was especially designed), engine makes about 155 revolutions and 1 1 knots. This is found to be the mo.st eco- nomical speed, all things considered. Under natural draught there is no trouble in running engines to 200 revolutions, which show.5 1234 knots by log. The Wooden Steam Yacht Reverie. This vessel was designed several years ago by Gustav Hillmann, the well-known and veteran naval architect of Brooklyn, N. Y., wdio designed J. J. Astor's magnificent iron steam yacht Nourmahal. The Reverie was built by Samuel H. Pine, Greenpoint, L. I., for the late Samuel G. Wilcox, but was afterward sold to Fred. G. Bourne, of New York. The yachtis j 10 feet long on the water line, i6feet8 inches beam, and 8 feet 7 inches deep, and draws 6 feet of water ; her registered tonnage is 92.15 tons gross and 53.48 tons net. The machin- ery was built under the .supervision of the Babcock & Wilcox Company, of New York, and con.sists of an inverted condensing triple-compound engine, with cylinders 11, 16J-2' and 26 inches diameter by 12 inches stroke, using 225 pounds pressure.

There is a Baird evaporator, with its pump capable of evaporating 400 gallons of water in 24 hours, a duplex pump 5 '4 by 3'j by 6 inches, and an injector for feeding the boiler. The steam is sup- plied to all these auxiliaries and the main engine by one Bab- cock & Wilcox marine water-tube boiler, 10 feet 6 inches long, 7 feet wide and 9 feet 7 inches high, constructed entirely of wrought iron and steel, there being no cast or malleable iron whate\'er entering its construction. The following gives the essential particulars relating to the boiler : Heating surface, 1,235 square feet ; grate surface, 40 .square feet; ratio of heat- ing surface to grate surface, 31 to i ; weight of boiler (dry), 20,515 pounds; weight of boiler (wet), 26,084 pounds; weight of boiler per .square foot of heating surface (dry), 16.16 pounds ; weight of boiler per square foot of heating surface fwet) , 21.12 pounds. During a test of the boiler for capacity, 506 horse-power (one horse-power being equal to 15 pounds of water evaporated into dr\' steam, triple-compound engine practice ) was easily developed for eight hours of continuous steaming. This is equivalent to 12.6 horse-power per square foot of grate. The Steam Yacht Oneonta. This craft was designed by Gardner & Co., New York, and built in 1S95 at the Delaware River Iron Shipbuilding & Engine Works, Chester, Pa., for F. C. Dinninny, of this city, and is a departure in many ways from the ordinary type of steam >acht, being designed with a \'iew to both conilort and speed. Her dimensions are: Length over all, 140 feet; load water line, 132 feet; beam, 19 feet 6 inches; draught, 7 feet. She is fitted with a water-tube boiler of the Daring type, of about 2200 square feet of heating surface and 55 square feet of grate, built of selected material to .stand 600 pounds. A pecu- liarity of this boiler being that no rivets are used, the drums being welded up by the Continental Iron Works, and thus all danger of leakage due to expansion of joints, caused by the high pressure u,sed in this type of boiler, is prevented. The engine is of the triple-expansion type, three cylinders 15, 23, 35 by 16 inches; indicated horse-power, 1000; revolutions, 400 per minute. This engine is balanced by Normand's method of placing the low-pressure cylinder in the center, and thus avoid- ing the severe racking couple that results when the revolutions coincide with the period of vibration in the ordinary type of marine engine. The auxiliary machinery is independent, except the air-]Hunp, which is direct. Forced draught on the closed fire-room principle is in.stalled, but .seldom used, as suffi- cient steam for ordinary running can be secured by natural draught. The Oneonta, in a trial run, covered 100 miles in 5 hours and 6 minutes, or nearly 20 miles an hour, which is not bad when it is con.sidered that the yacht is not built as a fiver, but has as much room as any yacht of her size afloat. The hull of the boat is of steel up to Government .standards in every particular; flush decked with large dining saloon forward and ladies' deck house aft. In appearance the Oneonta resembles a Government despatch boat, and the effect, while odd, is not displeasing.

All the woodwork above deck, including cabin.'s, bulwark.s and seat is of mahogany, with the exception of the rail, plank shear and hou.se coamings, which are of teak. The two pole spars are of white pine and very light, and step on top of cabins so as not to occupy valuable space in cabins. The motive power consi.sts of a triple-expansion engine with cyl- inders 9, 14 and 23 by 14 inches, driving a Trout wheel 4 feet 6 inches diameter and 6 feet 6 inches pitch. In order to take up as little fore-and-aft space as possible, the vah-es, which are all piston type, were put on the side of cylinders and operated by Marshall radial gear. The cylinders are placed in the order of high, intermediate and low. The bedplate is cast iron of the girder type, with five main journals and a tb.rust bearing of the horseshoe type with two collars cast on. The crank shaft is .solid forged with cranks at 120 degrees apart, in the following order: Intermediate, high-pre.ssure and low-pressure. All working parts are made as light as possible with all rods and bolts of machinery steel. All main journals and crank-pin brasses are lined with anti-friction metal. The general .style of the engine, which is designed for a piston speed of 950 feet per minute, is very clearly shown by the engraving. The sur- face condenser is a special style made by Dean Bros., of Indian- apolis, Ind., with combined air and circulating-pumps. The brass tubes in condenser are 5/8 inch diameter and 6 feet long, giving a cooling surface of 385 square feet. The diameter of air-pump is 9 inches, circulating-pump 9 inches, and steam cylinder 7 inches, with a common stroke of 10 inches. The total weight of the conden.ser and pumps is 4S00 pounds. Steam is supplied by a Roberts safety water-tube boiler, 8 feet 8 inches long, 8 feet 5 inches wide and S feet 4 inches deep. It contains two furnaces 3 feet 8 inches wide by 7 feet long, with grates for burning anthracite coal. The steam pressure allowed is 300 pounds per square inch, and at this pressure, with the engine making 350 revolutions per minute, a speed of 16 miles per hour is obtained. A special feature in connection with the machinery is a patent universal roller thrust bearing, made by Michael Schmaltz, of West Bay City, Mich. This bearing consi.sts of eight conical rollers running between two cast-steel di.scs, as will readily be .seen by the accompanying illustration. All parts of this bearing are well adjusted and the friction is reduced to a minimum, thus tending to increase the number of revolutions of the engine considerably more than when the HOWKLL'S STEAM A'KSSEUS AND MARINE 1-:NGINES.

The Wapiti's straigln stem and low freeboard gives her the appearance of an ocean steamer. The vessel and her machinery were built from designs of vS. Anderson, chief engineer with F \\\ Wheeler & Co. Steam Yachts Built by Wm. Cramp & Sons. Though steam >'aclit building is not usualh' a profitable part of the work of a shipyard, the Cramp Company lias from time to time undertaken the construction of vessels of that character. The most important of these yachts are enumerated: The Corsair ( since renamed the Kanapaha ) and the Stranger were built in iSSo, and delivered to their owners, Messrs. Charles J. Osboru and George Osgood, of New York, in July of that year. Tiiey were substantially sister ships, having the same principal dimensions and type of machinery, with only minor differences in trim and interior fittings. The>- have been constantly in use during the 14 years of their existence, performing satisfactorj- service to their owners at extremeh' small cost of overhaul and repair. Their dimensions are as follows: Length, 165 feet; extreme beam, 23 feet ; draught of water. Corsair, s feet : Stranger, g '4 feet ; displacement at that drau.ght. Corsair, 2,S'"< tons ; Stranger, 330 tons. They are powered with two-cylinder vertical inverted compound engines, having high-pressure cylinders 24 inches and low-pres- sure 44 inches diameter with 24 inches stroke. They are each provided with a pair of single-ender boilers 1 1 feet diameter by i'~i feet fi inches long, and carrying steam at So pounds this motive machiner}' developed 600 indicated horse-power on trial, and produced a speed of 13'- to 14 knots. The next important steam yacht built b)- Cramp was the .\talanla, delivered to Ja> Gould in June, iS,S3. This yacht was subsequently lengthened and her jtower increased. Her dimensions, as len.gthened, were as follows ■ Length on water line, 22,s.'4 feet ; extreme beam, 2(Sij feet ; mean draught of water, H' leet 2 inches : displace- ment at that draught, 617 tons. The Atalanta is propelled b>" a two-cylinder vertical compound engine, with cylinders respectively 30 and 5o inches diameter and 30 inches stroke. Steam is supplied by a pair of doubte-ender return tube boilers 13 feet 4' J inches diameter by 14 feet long. The maximum indicated horse-power developed by the Atalanta s macliiner\- occurred during the memorable steam \acht race in Long Island Sound in 1SS6. It was 1,340, and gave her a mean speed of 17.3 knots over a course So' . knots in len,gth. .Subsequenth' Mr. Gould made several extended cruises in her, on one occa- sion \'isiting the Levant as far as Constantinople. She has remained in the possession of his children since his death. In i,sS3 the Cramp Company decided to make a practice trial of the iirinciple of triple-expansion, and not being at that moment able to induce any of their commercial customers to undertake the innowation in a ship, they Iniilt a steam yacht known for some time In- her ship\-ard number "246," liut subsequently, when sold to Charles \V Harkne.ss, of Cleveland, Ohio, christened the Peerless. Being powered with one of the first triple-expansion engines built in America, and the development of that type being in its infanc>- elsewhere, the performance of " Number 246" was watched with great interest by the engi- neering profession. Her dimensions are : Length on the water line, 152 feet 7 inches : extreme beam, 22 feet ; mean draught of water, 8 feet 2 inches ; displacement at that draught, 260 tons. Her triple-expansion engine is vertical, three cvliuder : high-pressure 17 inches, intermediate 24 inches aiM low-pressure 4c inch es diameter with 22-inch stroke. HOW'KLTv'S STEAM X'KSSlvLS AND MARINE ENGINES. 121 Steam is supplied l)y one cylindrical boiler 12 feet 10 inches diameter b)- 1 2 feet long. The working pressure is 180 pounds, and the resultant maximum indicated horse-power developed in the yacht race already referred to was 816, producing a maximum speed of 17.4 knots per hour under forced draught. It is worthy of note that this early application of triple-expansion in America was made with a steam pressure 213 pounds greater than has since been employed here, and 50 pcjunds greater than had beeu attempted up to that date abroad. After remaining in possession of the Cramp Company about two years, the Peer- less went into .service on Lake Erie, where she has .since held the record for speed over all pleasure craft, and until very recently over the entire .steam fleet of the Ckeat Lakes. In fact, she is excelled in speed now only by the ver}- latest and largest passenger steamers in those waters. During the >ear following the advent of the Peerless, a pressure of naval and commercial work caused the Cramp Company to decline a number of proposals for steam yachts, until in 1893, J. Harvey Ladew, of New York, expressed a desire to own the fastest pleasure vessel afloat. The result was the beautiful little vessel represented in the picture and known as the Columbia. Her dimen.sionsare: Length on load water line, 180 feet; length over all, 202 feet ; extreme beam, 23 feet ; mean draught (cruising trim), loi-x feet; displacement at that draught, 526 tons; probable best racing draught, g'- feet; displacement at racing draught, about 436 tons. She is powered with a four- cylinder triple-expansion engine, cylinder diameters respectively, high-pres.sure 21 ^^'2 inches, intermediate- pres.sure 31 inches, and two low-pressure 44 inches each. Steam is supplied by two single-ender return tube boilers 12 feet 2 inches diameter b}' II feet 5 inches long, with a working pressure o*^ 160 pounds, and developing under forced draught a maximum of 1,900 indicated horse-power. The Columbia having been made ready for trial, left Cramp's yard for New York, and on Tuesday, December 19, 8:25:41 A. M., Mr. Flagler's hou.se, at Larch- mont, L. I., bearing directly abeam, she started on trial over the New York Yacht Club course from Larchmont to the Pequot House, New London, distant 80.52 knots, which .she reached at 12:56:24. The mean speed was 17.85 knots equal to 20.53 statute miles an hour. During this run, between two intermediate points, namely, Stratford Shoal Light and Falk- ner's Lsland, a distance of 22 knots, her speed was 18.35 knots. This was due to the deep water in that part of the cour.se, the depth in other parts not being sufficient to prevent dragging to .some extent. At a mean speed of 18 knots this vessel requires a depth of water at least fifteen times her own draught to avoid dragging. In view of the difficulties of the course and the fact that the yacht, when in water of sufficient depth to give her a fair chance, exceeded 18 knots, she was promptly accepted by her owner. The Steam Yacht Eleanor. The Bath (Maine) Iron Works built the steam yacht named Eleanor, to the order of William A. Slater, of Norwich, Conn. The Eleanor was designed by Chas. R. Hanscom. The principal dimensions of the Eleanor are: Length over all, 231 feet; length, load water Hue, 208 feet; length, keel, 1S5 feet; beam, extreme, 32 feet; depth of hold, 17 feet 5 inches: mean draught, 13 feet 4 inches; displacement, 1,136 tons. She is con- structed of steel throughout. The propelling power consists of a vertical iinerted direct acting triple-expansion engine, with cylinders 18, 2S and 45 inches diameter by 30 inches stroke.

The machinery consists of a triple-expansion engine of gi^, 15 and 24',: inches diameters with a stroke of 13 inches, built hv the Fore River Engine Co., of Weymouth, Mass. Steam is furnished b_\' a double fire box water-tube boiler of the Almv t\-pe, licensed to carr\' a pressure of 250 pounds to the square inch. The circulating, air, feed and bilge-pumps are all independent and are arranged to exhaust into the low-pressure recei\"er of the condenser. Pistons are of cast steel with spring rings as lighth' constructed as is consistent with strength; val\-es of cast iron of jiiston type. The>- are actuated by a side crank shaft dri\-en from main shaft liy steel and raw- hide gears. The reverse is accomplished with a spiral sleeve, working on a spiral on side shaft. The spirals and sleeves are cut from the solid steel, making a compact and durable piece of mechanism. The engine runs without the slightest vibration, and turns a bronze, four-bladed propeller, 5 feet diameter 7 leet pitch, 320 revolutions per minute, with 200 pounds steam. The condenser is 6 feet long, 36 inches diameter, copper shell, brass heads and tubes, contains 650 feet cooling surface.

The cylinders are placed in the order of high, intermediate and low, with high-pressure and intermediate valves between their respective cylinders, and both low-pressure valves between the intermediate and low cylinders. Dwing to the limited space, the high-pressure and intermediate cylinders were cast together, and the intermediate and low-pressure were connected by a steam belt around the former c}dinder. The ports in the high-pressure c_\'linder are i .^4 by 9 inches, in the intermediate cylinder 2 'Y by 15 inches, and 3 '4 by 26 inches in the low. The main steam pipe is 5 inches diameter, and the exhau.st pipe to the condenser is 11 inches diameter, both pipes being of copper. The throttle valve is of the bal- anced cylindrical type and fitted with a relief valve. Steam is admitted in the middle of the high-pressure valve to the high- pressure cylinder, exhausts at both ends directly to the inter- mediate valve, from the middle of which it exhausts into a belt around tlie intermediate cylinder directly to both ends of the low-pressure valve, and exhan.sts from the inside of the valves to the condenser. The cylinders are fitted with piston valves throughout, of the following diameters: High-pressure, 5}^ inches; intermediate, 8 inches, and two 8 inches on the low- HOWELL'S STEAM A'ESSELS AND MARINE ENGINES. 129 pressure.

All valve stems are ij4 inches diameter of machinery steel, and work in adjustable guides fitted with bra.ss bushings. The low-pressure valve stems are connected together by a wrought- iron cro.ss-arm, and one set of eccentrics and links work both valves. The eccentrics are cast iron two inches wide, with cast-iron straps. The engine is supplied with steam reversing gear, having a c3'linder 5 inches diameter and 8 inches stroke, operated by differential valve motion under easy control of the engineer. All pistons are cast-iron discs, 3^2 inches deep at sides secured to piston-rods by quick taper and nuts. The pis- ton-rods are 25?, inches diameter of machinery steel forged .solid with the crossheads. The .slippers are provided with brass gibs 11 inches deep by 8 inches wide, and the gudgeon is 3 '4 inches diameter by 5 inches long. The coiurecting-rods are also of .steel, 40 inches between centers, 2 'c inches diameter at upper ends and 3',° at lower, with upper end worked to suit crosshead. The bolts in crossheads are ifh inches diameter, and in connecting-rods are i'^ inches diameter, ter, and 1 3^ inches thick. The horseshoe collars are faced with anti-friction metal, and are adjusted by means of .steel bolts and brass nuts. All crank-pin brasses and main journals are lined with anti-friction metal. The cylinders are covered with mag- nesia and lagged with highly-polished mahogany. All revers- ing gear is placed on the back of the engine, thus giving an open front with free access to all journals and working parts. The .surface conden.ser is independent of the engine and has 79550 inches bra.ss tubes, 19 vS. \V G. 6 feet 6 inches long, giving a cooHng surface of 847 square feet. The air and the circulating-pumps are of the Blake combined type with steam cylinder between; size, 8 by 9 by 9 by 10 inches. Throughout the whole engine everything is finely finished and compares favorably with the best class of high-speed yacht engines. On the trial trip in Saginaw Bay, the engine made 250 revolutions per minute with 200 pounds of steam, and everything worked nicely. The engine was built from designs made by S.

She was constructed that sum- mer. Her dimensions are as follows: Length overall, 85 feet; load water line, 72 feet; beam, 14 feet, draught, ,=; feet. She was designed as a small family cruiser, with an average speed of 12 miles an hour. The Wooden Steam Yacht Calypso. Built by the Atlantic Works, of East Bo.ston, in 1894, for Harry E. Converse, of Maiden, Mass. The hull is of wood. The principal dimensions are ; Length on load water line, 102 feet ; beam, 17 feet ; draught, 7 feet 4 inches, with tanks and bunkers full and all stores on board. Her engines are of the fore-and-aft vertical inverted direct acting compound type, with cranks set at 90 degrees. The cylinders are 12 and 22 inches diameter, and the stroke of piston is 16 inches. The main valves are of the piston type, and are actuated b3' a Stephenson link motion. She has a c\lindrical surface condenser with 400 square feet of cooling surface. There are two independent feed- pumps, and a combined air and circulating-pump, all rif the Blake type. There is a Hancock locomotive inspirator and a bilge ejector. There is an auxiliary suction pipe and valve from the circulating-pump to the bilge for use in case of emerg- enc)-. She has thus three different methods of feeding boiler and four different wa\-s to discharge from the bilge. The boiler is of the Almy double-tube t>pe, the safety ■v-ah'c being set for a working pressure of 130 pounds. The Steam Yacht Embla. This craft was built in 1893 by Chas.

The steam launch \\'ild Duck was built by Simpson, Strickland & Co., Dartmouth, South Devon, E;no-land. The boat is 36 feet long b_\- 6 feet beam, has engines with c_\'linders 3-'4, 6 and 9 inches b>' 5 inches stroke, and a water-tube boiler of the firm's patent marine t>'pe. Her machinery space is onlv 10 feet of her length. On her trial trip she made 16 miles an hour. The working jjressure is i So pounds, and the engine runs at about 750 revolutions. The engine is too .small to in- dicate satisfactorily at this speed, but from the pressure in the cylinders and the revolutions, the builders estimate the indi- cated horse-power at aliout 50. The engine is illustrated bv a front elevation and end elevation at the low-pressure c)linder end. The>- are of the usual design of the firm, with cast-steel bed frame and back standards, and turned steel vertical columns in front. The Wild Duck is intended for sea service. Clipper Ship Morning Light. The immediate precursor of the modern "ocean gre\- hound," was the clipper ship of the forties and fifties. In the infancy of steam naviga- tion, the stately clippers, witli their splendid hulls, great spars and enormous spread of canvas often out- stripped the steamers. One of the most celebrated and successful clippers of her day was the Morning Li.ght, built by William Cramp, in 1853, for the ac- count of Buckner & Mc- Cammon, of Philadelphia. The ' ' poetry of the sea ' ' became idylic in these „ ,., ,. winged ships, which rode the waves niore like living creatures than like mechanical structures The Morning Light has been preserved bv the cun- ning hand of the arti.st, that the generations who .see only trans- atlantic hners in commerce, and hu.ge floating castles bristlino- with turrets and casements and clad with th'ick steel for wai' may know m what kind of ships their forefathers went down to tlie sea. The Morning Light was one of the smallest of the HOWETj;s STEAM A'ESSIvI.S AND MARINE ENGINES.

Cramp during- that period, but none of the others has been preserved b}- art. The Bridgewater was nearly twice the tonnage of the Morning Light, as was also the Manitou. They were all of the .same type, and the shipbuild- ing records of that time agree that the full-rigged clipper ships of the Delaware represented the perfection of naval architec- ture, and for many years spread the fame of the American shipyards to ever\- quarter of the globe. Larger sailing ships have since been built both in wood and iron, but so far as model, seaworthiness and symmetry are concerned, the>- ha\-e not been improved upon. The supremacy of Philadelphia in the shipbuilding art was established before the beginning of the century, and the sailing record between Cape Henlopen and Liverpool is still held by a Philadelphia ship, the Rebecca Sims, built in 1800, of which further mention will be made. Thus the competitors whom William Cramp had to meet with at the outset of his career, were masters of the art, and to hold way with them he had to build ships rating with the best in the world. The Morning Light was principalh- emplo_\-ed in the California trade around Cape Horn, in which she made a num- ber of remarkabh- successful voyages. Though, as already re- marked, much smaller than other Cramp-built clippers, she was considered one of the best sea boats, and fastest and mo.st weatherly sailers of her time. 13^ HOWELL'S STEAM \'ESSELS AND MARINE ENGINES.

The builder of this .ship is the founder of W ebb s Academy and Home for Shipbuilders, at Ford ham Heights, NY He is spoken of as the ■' Grand Old Man" of American shipbuilding. One of the features of this ship that every sailor will readily notice, is that she has only a sinrfe mizzen topsail, containing three reefs, while the fore and main topsails are double. Capt. E. C.

Glasgow to Otago, New Zealand, G8 days. Otago to Callao, 36 days. San F"iancisco to Hong Kong, 47 days. Manilla to New York, 98 days. She beat the American ships Invincible and David Crockett and the British clipper Ther- mopylae on .several occa.sions. The Young America once made 15 knots an hour for 80 hours while under comntand of Capt. Horace T. Bader, of West Yarmouth, Ma.ss. One of her commanders was the late Capt. David S. Babcock, who was afterward President of the Providence and Stonington Line, and the father of W . I. Babcock, General Manager of the Chicago (Illinois) Shipbuilding Company. George Howes, of New York, says he never saw a more beautiful ship than the Young America. She had a counter like a pilot boat. A good drawing of the Young America will be found in Webbs' Work on Shipbuilding, by Wm. H Webb. The Wooden Ship Aryan. The illustration represents the last wooden .ship built in the United States. The Aryan Cmeaning the last of her race) was launched on July 13, 1893, from the yard of Charles V. Minott, Phipsburg, Maine, and is owned by her builder, Jas. W. Elwell & Co., New York, and Capt.

The dimension.s of the vessel are as follows: Length, 248 feet 6 inches; beam, 42 feet 2 inches; depth, 26 feet 3 inches; net tonnage, 2,017; gross tonnage, 2,123. She cost about $45 per ton, ready for sea. Her crew number 25 men. The Aryan can carry 3,400 tons of wheat. One of the great influences that has brought about the decadence of the American sailing ship is the change from wood to iron in their con- struction. Another important factor in driving American ships off the sea has been the change from sail to steam, and, lastly, the advent of the low priced, cheaply manned and cheapl}' run British tramp steamer. The new tramp steamers, with triple and quadruple-expansion engines, will carry 4,000 tons of cargo on a consumption of only 15 to 20 tons of coal per day, making a speed of from g to 10 knots an hour. Their crew consi-sts of only from 8 to 10 men before the mast, about the same number of .stokers, and in some cases only two en- gineers. A sailing .ship of 4,000 tons capacity would require from 25 to 30 sailors. Another era in cheap ocean transporta- tion is dawning — we refer to the turret deck or whaleback type of steamers with quadruple-expansion engines and water-tube boilers. A fleet of turrets have already been built. These vessels are cheap to build, cheap to run and easily kept in working order. They represent the very acme of economy in the construction and running of cargo steamers. This, then, is one of the greatest factors in forcing our American sailing ships off the face of the waters. The building of the Nicaragua Canal will complete the work of final extinction. The First American Steel Sailing Sliip. Dirigo ( meaning in Spanish " I direct" ) was designed and built by Aithur Sewell & Co., of Bath, Maine, who own her. The general dimensions are: Length, 312 feet; breadth, 4515-100 feet; depth 25 6-10 feet; gross\onnage,' 3,004.80 '; net tonnage, 2,855.79. These figures are Custom House or official measurements. The name of the vessel is the motto of the State of Maine. She was launched February 10, 1894. She spreads about 12,500 yards of canvas. Her three skysail yards give her a clipper-like appearance. ' The ship is designed to carrv a full cargo on 22.6 feet draught, and to stand up without ballast when light in port. She has a flush main deck of .steel fore-and-aft, the whole of which IS sheathed with 334-inch hard pine planking. The lower deck has steel .stringers and tie plates, and is planked HOWEI^VS STKAM VESSELS AND MARINE ENGINlvS. 139 /C^^^V^&4!<(feW.V,^^*ifttert««^'i The FAMdrs Vankhk Packet vShip Drkahnought, which was Co^mmaniird by Cattaix S.

The smaller deck house aft is fitted up for the accommodation of all the apprentices and petty officers, also containing the carpenter's shop. There is a large full poop aft, in which is the captain's accommodation, and a saloon, 16 feet square, on the starboard side. The mess- room and pantrj' is in the center, while the officers' cabin and two spare staterooms are fitted on the port side, the sail-room occupying the space right aft. On top of the poop is a steel chart house which also forms a cabin entrance. The helms- man is protected by a .steel hood, open on the forward end. A large flying bridge is fitted, connecting the poop and topgallant forecastle, and proves a great convenience in bad weather. The scantlings of the vessel are equal to Lloyd's. The lower masts and topma.sts are in one length, measuring 134 feet ; the pole bow.sprit, 67 feet long ; the lower yards, 92 feet long, and the upper and lower topsail yards are all of steel. A large crane is fitted on each side of the bow for working the anchors. Though costing a little more than a wooden hull, the advantage which steel vessels always have over wooden ones in command- ing freights, has made her as profitable as her big predecessors, Roanoke, Susquehanna, and Shenandoah.

She is capable of making 131- knots an hour in a good breeze. We are not aware of the cost of the Dirigo, but a rough estimate would place the figures at $150,000. The Packet Ship Dreadnought. This renowned .ship was built at Newbury port, Mass., in 1853, by Wm. Currier and Jas. T. Townsend, for David Ogden, Gov.' E^ D. Morgan and Capt. Samuel Samuels, under the super- vision of the latter. By the sailors she was nicknamed the " Flying Dutchman." She was what might be termed a .semi- clipper, and posses,sed the merit of being able to bear driving as long her .sails and spars would stand. She was 200 feet long between perpendiculars, 217 feet on deck, 40 feet beam, 26 feet deep; tonnage, o. m., 1,443; "sL 1,227; carrying capacity, d.w., 1,700 tons. " It has been said that with a strong leadnig breeze and all .sails drawing, nothing was ever allowed to pass the clipper Dreadnought, not even a steamer. Her first return trip was made in Februarj', 1854. On that voyage she scudded into celebrity by reaching Sandy Hook as .soon as the Cunard steamer Canada, which had left Liverpool one day earlier. In 1859, made the 3,000 miles from Sandy Hook to Rock Light, Liverpool, in 13 days and 8 hours ; and in 1S60, went from .Sandy Hook to parallel of Queenstowii, 2,760 miles, in the unequalled sailing time of 9 days and 13 hours. In April 1S69, the famous ship left Liverpool in command of Capt. Mayhew, bound for San Franci.sco, and was wrecked on the morning of the Fourth of July on Cape Penas, N. E. of the Island of Terra del Fuego. She had a cargo of 2,000 tons. Her loss was occa.sioned by her having anchored nearer shore than was supposed, and when the breakers were discovered she was becalmed and drifted with the current. The crew, 34 in all, had hardly time to get into two boats which they succeeded in lowering, saving none of their effects but the clothes they had on, and not a mouthful of provisions. For days they subsisted on the shellfish which they gathered from the rocks at low tide. By day they pursued their course southward, toward the Straits of Maire, and on the 17th day after their wreck fell in with the Norwegian bark General Birch, who.se captain, A. Amersden, treated them with all possil.)le kindness and attention. The HOWELL'S STEAM VESSELS AND MARINE ENGINES. 145 Steei. Bark Projected by Cart. Chas. H. Nelson, oe Boston, Mass. Birch landed the sufferers at Talcahauno. Ten of them were left in the hospital at that port, and lost their toes, which were frost-bitten. Thus ignominiou,sly ended the career of America s greatest and fastest western ocean passenger ship. The per- sonality of Capt. Samuels is not less conspicuous than was the name and fame of his ship. He won an international reputa- tion in command of the yacht Henrietta, in the ocean yacht race against the Vesta and Fleetwingin December, 1866. Lapt. Samuels has added to his laurels by writing a book of lite at sea ,n sailing ships, entitled, "From Forecastle to Cabin, ' publi.shed by Harper & Bros., New York. This book is the best pen picture of a .sailor's life, outside of ' 'Two Years Before the Mast, by Richard H. Dana. Capt. Samuels is now, and has been for the past six or seven years, one of the proprietors of the ^z^Yor\. Marine Journal of which Capt. George L. Norton is editor and manager. The Dreadnought was commanded by Capt. Samuels from the time she was built until iS63^ covering the period of her career as a Liverpool packet. The Dread- nought carried a fiery cross painted on her fore top.sail, and was readily recognized at sea by this characteristic. The three following stanzas are from a ballad, entitled, " The Dread- nought, ' ' which was once the choice windlass and capstan .song, or shanty, of both American and British packet ship sailors. The ballad contained some eight verses. There's a saucy wild packet, and a packet of fame. She belongs to New York, and the Dreadnought's her name; She is bound to the westward where strong winds do blow. Bound away in the Dreadnought to the westward we go. Oh ! the Dreadnought's a-bowling down the wild Irish .shore, Captain Samuels commands her as he's oft done before, While the sailors like lions walk the decks to and fro,-- Bound away in the Dreadnought to the westward we'll go. Here's health to the Dreadnought and to all her brave crewl Here's health to Captain Samuels, and officers, too! Talk about your flash packets.

Tht first fiinr-inasted slii]i, of what we might call the ne\\' era of American wooden sailing ships, was huilt about the year 1S74, hy J. Henr>' Sears, uf Biiston, and called the (Jcean King. This ship was fore-and-aft rigged on tlie jig.ger mast, a-^ all four-masted American shijjs are. It is enough to swing fore, main and niizzen \-ards in tacking shi]), and reef and furl sails on the three masts without adding another set of \ards, which experience has pro\-ed are iiseless for jiractical purposes. All our American four-masters can be comUed on the fingers of one hand. The Roanoke was Iniilt by Arthur Sewall & Co., of Bath, Me. Her length on the keel is 311 feet, and her length o\'er all is ^^^i feet. Her extreme lieani is 49. ,, feet, and her depth 29. I feet, and her drau.ght 27 feet. Her main and mizzen lower masts are 92 feet high, and her fore lower mast is 91 feet hi.gh. Her lower spanker mast is i;S feet hi.gh. The Roanoke has loaded over 5,oor) tons of general cargo. vShe carries a crew of about 40 men. The Shenandoah, a sister ship, is 3,25.^ tons register. The Rappahannock, which was burned, was 3,053 tons. The Susquehanna is another four- master of about 2, goo tons register. The half-tone cut of the Roanoke's rigging shows the modern wrought-iron turn-l)uckles now u.sed altogether instead of the old-fa.shioned hem]i lan- yards. One man and a boy can nriw do tlie work of a wdiole watch in setting up the rigging, and can do it in less than one quarter of the time occupied \>y the old wa_\-.

The illustration represents the ( )lynipic, the onh" four- masted bark afloat, and the onl>- wooden ,sailing \-essel capable of crossing the Atlantic or douliling Cape Horn with a clean- .swept hold and without a pound of l)allast of an>- kind in the same. This ^-essel was built in 1S92 bv the Xew Lhi.gland Co., of Bath, Me., for Capt. \V. H. Be.s.se, of Xew Bedford, Mass., and others. She carries double topgallant yards and a main skysail. Her deadweight capacity is about 2,3.j(.i tons : full capacity for lumber, 1,4010,000 feet on 19 feet of water. Di- mensions: Length, 224 feet ; beam, 42 feet 2 inches ; depth of hold, 21 feet. vShe is provided with two bow ports, 36 inches square, and two stern ports 32 inches square, to enable her to take in spars or long square timber. All the standing rigging, bobstays and jib guys are set up with screws or turn-buckles, no deadeyes or lanyards being used even for the topmast rigging. The Olympic .spreads 80,000 square >-ards of cam-as. Ller fore and main }-ards are each 84 feet long ; the hatches, three in num- ber, fore, main and niizzen, are each 20 by 16 feet. Carries 233 tons of cargo to the foot. The vessel is especially fitted for the Oregon timber and spar trade. X. 1). Sinclair and Benjamin Moore are owners with Capt. Bes.se, whose .son, W vS. Be.s.se, of Xew York, is the ship's agent at this port. The two most remarkable points about the Olympic are her rig and tlie fact that .she can sail \vithout ballast with sk>-sail )-ard aloft, and still stand u]i as stift' as a church. The lo\\er rigging is rattled down with galvanized gas pipe, wliicli lasts as long as the shrouds, the latter being of liest steel wire. The Olympic is 1,469 tons gross and i,4r"j tons net register. Some twenty years ago there was built by the Harlan & Hollingsworth Co., of Wilmington, Del., an iron bark called the Iron Age. Since then no iron vessel of that rig has been constructed in the United States. True it is that the lamented Commander Henrv R. Gornnge, of the U. S. Navy, constructed the iron ships T. F.

Starbuck, was also built by John Roach, at Chester, Pa These and the Dirigo complete the fleet of American iron sailing vessels. There is one man in New England, Capt Charles H. Nelson, Boston, Ma.ss., who thinks that the United States can turn out as good a specimen of a steel square-rigged vessel as any country in the world, and he has had plans drawn for the construction of a steel bark of 1,398 tons. Her estima- ted cost will be about $100,000. A look at the plans will con- vince the most sceptical of the ultimate success of the bark as far as her lines, carrying capacity and construction go. Her length will be 220 feet, 36 feet 8 inches breadth, 22 feet 6 inches depth. The Largest Sailing Vessel in the World. A little more than three years have pa.ssed .since the proud German five-nia.ster Maria Rickmers started from an English port on her second voyage, from which she never returned. Only one sailing ves.sel of similar dimensions has been Vaiilt since I we refer to the French five-ma,ster Ea France) ; but now Germany has become the posses.sor of the largest sailing ve.ssel in the world. On June 8, 1895, the five-master Potosi was launched from the yards of Tecklenborg, and made her first voyage to Iquique, a distance of 11,000 miles, in 72 days, arriving at that port early in October. The vessel is owned by the well-known Hamburg house of F. Eaei.sz. The Potosi is about 426 feet 6 inches long, 52 feet 5 inches broad, and 32 feet 9 inches deep. She has a capacity of 6,150 tons, or 550 tons more than that of Ea France. The uninitiated may obtain a better idea of the great size of this vessel from the following figures; 5,51 1,500 pounds of iron were u.sed in its construction, and the vessel, which will make regular trips to the western coast of South America for saltpeter, can carry about 13,227 bags of this salt. 146 HOWELL'S STEAM VESSELS AND MARINE ENGINES.

I-acht which, although dating several years back, gives no leeway to similar foreign yachts. Built in Havre in 1875 by Augustin M. Normand, who obliged us with the plans, the Velox .shows remarkable improvements and special features, showing a great ad\-ance over foreign con.structions, as these novel forms were only applied later to a number of celebrated foreign }-achts in her wake. 'Mr. Che\-reux, in an elaborate article, published in T/ie I'tT^/// of April 13, 1895, has, moreover, brought out forcibly these characteristics which are found in certain racing yachts recently built in England. The outlines of the A'elox, a combination of tho.se then in u.se partly in England and in America, call at first for stability of ballast and for width of water line. The hull of the Velox is, there- fore, in reality a conglomeration of two hulls brought together b}' softened curves, a broad hull with a weak depth on the lines of the celebrated Sappho and under that upper one another very nar- row one, very high, intended to receive the ballast. The length of the second receptacle is so great, in propor- tion to its width, that its resistance is hardh' more than the surface friction, and, notwith- standing the capacity, is such that it can accommodate in a low draught, without injuring the stability or .solidity, all the bal- last necessary. The center volume is placed at a slight distance from the water line and the dLsplacement rather le.s.sened, .so that the hight of the metacenter ( half center ) above the center ( which is inversely proportionate of the displacement ) becomes con.siderable. The metacenter is located i meter and 42 centi- meters above the water line. This is of exceptional value for a yacht having a great stability of weight. It will be .seen what enormous distance from the center of gravity to the metacenter could be po.s.sibly obtained if the total of the ballast was lead and if the lower hull was consequently reduced. The low- displacement in proportion to the volume of freeboard, allows the ship to rise \'er>' easily with the wave, and the nautical qualities are ver}' good indeed. The board lines are compo.sed of two diagonal and one longitudinal line. The first, running from front to rear, are only present in the center part. The second, running in an oppo.site direction, covers the ends in connection with a longitudinal outer layer. There are, there- fore, three thicknes.ses of very thin woodwork in the middle and only two at the ends. These layers, powerfully riveted, form a surface as rigid as a metallic hull. It was also po.s.sible to allow a considerable distance between frames which admitted of a very light construction. Iron stanchions, in.serted into the sides, bind the bridge and frame and prevent a deformation of the tran.sver.sal lines. The keel is very large ( 96 cm. ;, hanging free in the center and supports a leaden keel. Tlie yacht is not at all intended for racing, and, moreover, the proportion of lead in the total make-up of the balla.st is exceptionally weak ( 25'- tons on S7 tons of total weight ). Yet the vessel carried very readily one of the greatest expanses of canvas of any existing yacht. Important modification would have been necessary if it was intended to apply the same .system of outlines to a racing vacht ; but it appears that the plan gi^•es a maximum of carr\-- iiig power and stability, which is the intrinsic moti\'e power of a .sailing vacht, as it conditions the quantity of canvas. The A'elox is b>- her dimen.sions, qualities and beaut>' of shape before all a high sea ve.s.sel and compares ad\-antageously with the best English and American yachts of her type. Let us quote by comparison now as to yachts of her kind, more recent constructions, like the Ambassadress ; the fine schooner Con- .stellation, by Burgess; Yampa ; Alcse : and in England, En- chantress, Cetonia, Waterwitch, etc. Let us compare the \'elox with the Coronet, which dates but from i,S,S6, and was built by C. & R.

A Pilot Boat for Fernandina, Fla. A. Cary Smith designed this pilot boat, of the following dimensions: Length over all, 93 feet; length on load water line, 72 feet; beam, 20 feet; draught of water, lo feet 10 inches. This boat is a wide departure from the ordinary pilot boat, but no more so than those the genius Geo. Steers used to build compared to the boats of that day. It has been shown that the modern yacht far outclasses her elder sisters in beating to windward in a sea way, not only in sail carrying power, but in getting over the water in.'tead of digging into it; and in running in a bad sea the modern overhang is much superior to the old short flat counter. Anyone who has anchored in a tide sea ".stern to" knows what it means when a sea strikes the short, flat counter stern of the old type. The stern overhang has always been held to be a great detriment in the judgment of seafaring men, but this judgment was formed on the prevalent flat counter stern, and when some years ago the owner of the steam yacht Meteor consulted Mr. Smith about putting on a long overhang on the .stern of that yacht, the idea was condemned bv all .sea- men, but not with.standing this, Mr. Smith put a stern on that measured 20 feet from the inner post. The captain of the boat, on his return from a trip to the West Indies, gave his opinion HOWELI^'S STEAM VESSKI^S AND MARINE EN GINES. 155 The Celehrathd Frrnch Schooner Yacht \'e;i,ox. 156 HOWELL'S STEAM \'ESSELS AND MARINE ENGINES. -I Thk CklkhraTko I'Ki-:NeH Schoonkk Yacht \'kl().\. — Built by M.

The explanation was that with the former short flat counter, the sea struck it with such force as to loo.sen the oakum. With the new stern the blow was received on a roundino- form that rafsed the boat without the tremendous shock the old stern used to get. Again, the schooner Itasca proved what the modern type of >-acht can do at sea. It is a remarkable fact, that the old yachts rarely made a fast run when the weather was bad. When the sea got up they were obliged to "heave to," even though the wind might be favorable. All the.se points have been given careful consid- eration in the design of the ]''crnandina boat. First there is a considerable drag to the keel and a good rake to the .stern post. These features insure quick staying qualities. The mainmast is placed in the same relative position as that of the Iroquois, and as the center of buoyancy is in the same position, this boat will also " lay to " with a main trysail. To insure .small head- sails, the forefoot has been well cut away as head sails give the most trouble at sea. The masts have considerable rake, as it was not deemed advisable for .such a boat to carry runners as yachts do. The fore topmast is very short compared to the main topmast in order to carry a large jib topsail with the wind free diu'ing siunmer weather, and a small one will be carried to windward. i5« HOWELL'S STEAM X'ESSELS AND MARINE ENGINES.

Up to 1 856 the mercantile marine of this country handled their chains with a wooden windlass with three turns around it, operated by a beam. The chain had to be overhauled for- ward of the windlass before making port, and where the range was uncertain or unknown, a vessel was liable to go ashore before the matter could be rectified. Wooden pumps were in use, and a modern steering wheel was a novelty. In 1856 James Emerson brought out his iron windlass, which revolutionized the old method. A vessel could anchor with any range, with one or Itoth anchors, without previous arrangement, and one or both anchors could be taken at once. Joseph P. Manton, of Providence, R. I., has since brought out many real improve- ments in this line, such as iron side bitts, improved deck pipes, pump brake, windlasses, locking gear, taking anchor by direct steam windlasses, also from donkey, etc. To meet the requirements of the fishing fleet, a windlass has been designed expressh' for them which is stronger than an}' wooden windlass, and the anchor can be taken in one-half the time. The drum for the rope cable, and wildcat for the chain, are independent of each other. As the drum revolves and is easily controlled by a friction band, the cable will la.st much longer. In anchoring with the chain, it is only required to shackle the chain to the anchor, and the whole range is under control. Some of the advantages that the new windlass possesses are, that it can be unlocked when under strain, its operation is i6o HOWl'JJ.'S STEAM \'ESSELS AXU \rARINE IvNGINES. \ ' [ - [ ■ 1 / . ,..i ' '' . v. ^ immMWB^Basmih KoliiMS Sp*t,5 .•■ '■ - -"S'i* •—■ - -^■■i SEraiP' > - ..-' ' ■ — - -..

By its use the life of cables is largely increased, a saving of some moment when their cost is considered. Special forms are made for steam or for using soft-cored wire rope. The Providence Fisherman's Windlass. The need of a windlass especially adapted to the require- ments of fi.shing schooners, engaged in the cod and halibut fisheries, has long been felt. The Providence fi.sherman's windla.ss, built by the American Ship Windla.ss Company, of Providence, R. I., fills these requirements, as will be seen by reference to the engraving. The port side of this windlass is fitted with a wooden or iron barrel or drum to accommodate a manilla cable of from six to ten inches or even a foot in cir- cumference, enough room being left between the welps of the windlass and the deck to allow the splices to pass clear at each ICO fathoms length, when the hawser is swollen beyond its natural size by being water-soaked. In this improved style the barrel or body of the windlass revolves with the cable while the latter is being paid out, and in this way prevents the wear and tear of rope caused by the friction of coming in con- tact with the sharp edges of the welps, which are bolted on the windlass body. The Providence pump-brake fisherman's wind- lass differs from, and is an improvement on, all other windlasses in regard to the barrel revolving in the direction of the cable when the anchor is let go. In this respect the manufacturers have accomplished .something that was supposed to be impractical : in fact, they have made an entirel}' new and original departure to in the workings of a windlass for fi.shing vessels. In addition the great saving in the wear and tear of the cable, brought about by this improved method, it is estimated that 500 fathoms of ma- nilla cable, costing onedollar per fathom, will last at least half as long again by using the Providence windlass. In handling the anchors they can be weighed in half the time formerly occupied, as the windlass runs perfectly true and without any lost motion. The anchor can be dropped instantlj', and after touching bottom the hawser will run out without any overhauling. The speed can be regulated by a hand at the brake. Three or four or even five turns of the hawser may be put round the windlass, so that in heaving the cable in, only one man is needed abaft the windlass to coil it away. In paying out the cable, this barrel revolves the same as a fi,shing reel, but is entirely under control of the man at the wheel or lever. The speed of either the cable or chain in running out over the " wild cat " on starboard side or the revolving drum on port side, is con- trolled by the friction band, which is actuated either by a lever or a small hand wheel, with or without spokes ; that is, if there is not room enough between the windlass and traveller boom to allow of a bar being used. The port side of this windlass can be worked independent of the starboard side, and vice versa, or both sides may be entirely disconnected from the main shaft which runs through from end to end, thus turning the windlass into a powerful winch, and leaving the ends free and clear for warping or hoi.sting purposes. The levers attached to the driving ratchet wheel are so arranged that they may be brought into the center of the working beam, thus procuring a double purchase for breaking out the anchor, after which they can be slid out to the ends of the beam, giving a quick speed again for running the anchor up to the hawse pipe. On the starboard side the windlass is fitted with a wild cat or iron grabwheel, to take one inch chain (or any .size desired), which will run from the chain locker on deck under an iron roller or pulley, placed abaft the windlass and over the wild cat, instead of having it come up from the locker below, directly under the windlass, as is the case on board of coa.sters and large vessels. The two iron pawls have an attachment by which they may be kept raised while the slack of the cable is being hove in, thereby making the windla.ss as noiseless as a silent-running sewing machine. This noiseless plan might be highly appreciated by the New England fi.sher- men, who now stand in mortal dread of being pounced upon by a Dominion cruiser early in the morning, through making such a clatter "heaving short" before dawn. In heaving up an anchor with this improved windlass, only one side need be used, thus saving the power expended on the old type of wooden windlass in heaving round the dead weight of the side not in use, and it also saves the time used in trycing up the chain on the starboard side. The arrangement of two iron pawls and one ratchet wheel accomplishes more than the old- fashioned windlass did with two wheels, besides giving a much stronger, more compact and convenient machine without any lost motion. The clamps on the new style windlass are made of heavy gun iron and the pawls of best forged Norway iron, so strong that they are capable of outlasting the vessel in all cases. This improved plan of handling ground tackle by means of the patent fi.sherman's windla.ss inu.st .steadily gain in favor with vessel owners and builders, as it is exceedingly valuable for the ease and rapidity of coming to an anchor and getting under weigh. The most important point gained by this inven- HowEr-,i.'s .Sei,f-AcTinc. Rinc, Bi HOWELL'S STEAM VESSELS AND MARINE ENGINES. 163 tion is the saving in dollars and cents to the user of this im- proved windlass. Hawsers lasting a year, worked over tlie old wmdlass, will last at least eighteen months or two years on the one here represented, to say nothing of the time and labor saved by its use. The attention of owners and masters of our New England fishing fleet is especially invited to the foregoing. For descriptive catalogue address Frank S. Manton, Agent, Providence, R. I.

Howell's Automatic Wave Lubricating Life Buoy. _ The device consists of a ring Ijuoy in the inner circle of which is placed a rubber tube, about one inch in diameter, which is filled with oil. Tliree or four inches from the ends of the tube there is inserted a light brass tube, small enough to fit snugly into the rubber, thus forming a tight joint. On either side of the brass tube there is fitted a brass rose ( sim- ilar to that on a sprinkling can or watering pot ) , \vliich is soldered to the former. There is also fitted a brass cap which is screwed into the metal tube, to Ije used for filling the rubber pipe with oil. When the buo\- is hung at the stern or on the vessels' quarters, the oil cannot escape, but the moment the buo}- is cut loose and thrown overboard, the oil automatically and instantaneously commences to leak out of the ro.ses, no matter which side of the buoy strikes the water. The most important feature of this in\'ention is that a man may be seen, or rather, the smooth patch of water where he is may be kept in sight by those on board his vessel, even though she has run a couple of miles away before being brought up into the wind and hove to. Many men are drowned after falling overboard because the peo])le on tlie ship lo.se .sight of them before a boat can 1)e lowered, but this simple and ingenious device proves an anti- dote to the turmoil going on all around, and provides an artificial mill pond, so to .speak, where the mariner may float in safety until he is picked up. This device is the invention of G. Foster Howell, of the Americaji Shipbuilder, but is owned and manufactured by D. Kahnweiler, 437 Pearl Street, New York. Captain William Tumbridge.
