MAIN ENTRANCE TO NILES W 
 
INTRODUCTORY. 
 
 I N issuing tliis Catalogue, we have endeavored to present such of our 
 ^ machines as are of general use, and concerning wliich we are in most 
 frequent receipt of letters of inquiry. We have necessarily omitted many 
 machines as being entirely too special to be of general interest, although 
 
 '^yje//^

 many of these even are adapted from some of our regular patterns. Estimates 
 and photographs of special tools will be cheerfully furnished upon application. 
 
 We desire also to call your attention briefly to our very superior facilities 
 for manufacturing machine tools. 
 
 We are prepared to furnish complete equipments for railroad, car, loco- 
 motive, boiler and machine shops. We have many special labor-saving 
 machines for various purposes which should find a place in every shop. Our 
 machines are fully abreast of the times, if not in advance, in convenience,

 power and weiiiht. We aim to meet all rL-quirements, and are work'ing 
 constanth' in the line nt impr<Aement and new labor-saving macliinery for 
 special purposes. 
 
 Our facilities tor manufacture are unexcelled. We ha\'e added largely to 
 our buildings and plant, and haw now, unquestionably, the largest shops in 
 this criuntrx' de\-i)ted e.\clusi\'el\' to the manufacture of machine tools. 
 
 Our main machine room is 400 feet long by 216 wide, in five divisions. 
 On one side is the lathe room, which is 50 feet wide, and fitted up with 
 overhead tra\'eling cranes. Here all lathe work is performed under the direct 
 
 super\'ision of a competent lathe fore- 
 man. This wing of the main building 
 is two stories in height and the upper 
 story is occupied by the light lathes, 
 gear -cutters, milling machines and 
 screw machines which do not require to be on foundations. 
 
 The next section is the main erecting shop. It is 50 feet wide and 32 feet 
 high under the trusses. It is fitted with pits and foundations suitable for the 
 erection of heavy machinery. Two overhead power traveling cranes, each of 
 25 tons capacity, span this section, thus equipping it for tlie handling of the 
 heaviest work. It is also traversed its entire length by a railroad track, which 
 enables us to load heavy machines on cars direct by means of the traveling cranes. 
 
 The third section, 40 feet wide, is the fitting shop. In it are the vises, 
 scraping benches, surface plates, and all tools and appliances peculiar to this 
 department. This room is 'also supplied with overhead traveling cranes of 3 
 to 10 tons capacit\'. Part of this shop is occupied by the tool room, which

 is thoroughly equipped with the most modern machinery for mailing and 
 repairing tools. It is furnished with standard gauges and templets and a very 
 full assortment of tools. 
 
 The next section is 36 feet wide and also 32 feet high under the trusses. 
 It has also an overhead power traveling crane of 20 tons capacity, which is 
 required to serve the large tools with which this room is furnished. Here are 
 located the Heavy Planers, Boring Mills, and Horizontal Boring and Milling 
 Machines, Radial Drills, etc., which are arranged to machine heavy castings 
 to the best advantage. 
 
 The last section is the planer room proper, 40 feet wide, which is filled 
 
 with Planers, Shapers and 
 
 ^ Slotters, all conveniently ar- 
 ranged, and IS well supplied

 with small overhead traveling cranes. All these sections are crossed by railroad 
 tracks leading from the foundry and other shops. 
 
 In addition to this well arranged system of shops, we have also two 
 others; one, 340 feet long by 45 feet wide; the other, 200 feet long by 48 
 feet wide, both thoroughly equipped with tools and tool rooms adapted to 
 the fitting and erection of our smaller machinery. Both are supplied with 
 overhead traveling cranes of from 3 to 6 tons capacity, and are connected 
 with the main system by railroad tracks.

 A lari^e fire-proot buikiinjj; on the opposite side of tlie street, entirely 
 isolated, is used for the storage of patterns. This building is i6o feet long 
 and 72 feet wide, divided into three compartments by fire walls. It is 
 arranged with two galleries and is lighted wholly from the roof. This is one 
 of the most complete and safe pattern storage rooms in the world. 
 
 The foundry consists of four sections. Three of these are arranged side 
 bv side, with the fourth at right angles to and adjoining. The first section is 
 300 feet long, and is supplied with two overhead power traveling cranes, 
 each of 20 tons capacity. The adjoining section is 140 feet long, and it 
 has also two overhead power traveling cranes of 15 tons capacity each. The 
 
 third section is 140 
 feet long and is sup- 
 plied with Jib cianes. 
 This room is used for 
 moulding small woik 
 mainly. The fouith

 section, at right angles to the others, is 170 feet long by 60 feet wide, and is 
 furnished with four jib cranes of 20 tons capacity, all driven by power. These 
 wings are used for moulding floors e.xclusively. Other rooms adjoining and con- 
 nected are used for core making, cleaning castings, and the cupolas, all connected 
 by railways and furnished with cranes for convenience in handling heavy work. 
 
 The blacksmith shop is 120 feet long by 55 feet wide, and is provided 
 with cranes, power hammers, case hardening furnace, bolt heading machines, 
 and every appliance to make the equipment complete. 
 
 Our shops are equipped with the best machinery and appliances for 
 producing accurate work at lowest cost. The buildings are thoroughly well

 lighted by an electric li;jht plant with i6o arc licdits and ;^as. They are 
 heated hv steam and hot-blast air apparatus. Altogether, the works occupy 
 abiiut fifteen acres, over ei;iht of wdiich are under roof. 
 
 Our facilities f(jr shippin^^ are unexcelled. Cars can be loaded directly 
 under our powerful traveling cranes and promptly delivered to any of the rail- 
 roads. Hamilton is a junctiiin point and has first-class railroad facilities for 
 shipment to all parts of the country.

 Driving Wheel Lathes. 
 
 ■ I 'HESE Lathe? all ha\-e two heads, face platt-s and carria;^es frir turning a 
 
 pair of dri\'ers on their axles at the same time. The\' ha\e ample power to 
 carr\" two hea\'\' cuts simultaneoush'. 
 
 The face plates mav be dri\'en together or separatel\\ as desired, and at the 
 same or different speeds. They are made of sufficient diameter to affijrd clamping 
 room for tires, to allow for boring. 
 
 The main spindles are of extra large diameter, with large and long bearings. 
 Each main spindle has an internal sliding spindle with sufficient tra\-erse to clear 
 the longest crank pins. 
 
 The dri\'ing shaft is a solid steel forging, extra large, free from torsion, and 
 hence insuring great steadiness of motion while the Lathe is taking heavy cuts. 
 
 All gearing, including the large face plate gear, is cut from the solid, 
 insuring the full bearing of the teeth, and smooth, stead\' running of the Lathe. 
 
 The face plate gears are not cast solid with the face plates, but are securely 
 bolted to them, and may, in case of accident, be readily replaced without the 
 necessity of replacing also the face plates. 
 
 The bed is triple web, of great width and depth. The front section forming 
 the slides for the carriages is carried up to secure great stiffness at the point 
 where the strain of the cut is taken, and to permit the use of \'ery short, stiff 
 tool rests. 
 
 The feeds are automatic, and arranged by a special de\-ice to secure proper 
 speeds for turning both tires and journals. 
 
 The right-hand head is arranged to slide, to accommodate axles of different 
 length. It is operated by powerful hand gearing. 
 
 QUARTERING ATTACHMENT. 
 
 Our Drix'ing Wheel Lathes may be furnished with Quartering and Crank- 
 Pin Boring Attachments on one or both heads, as may be desired. 
 
 These attachments are secured to heavy brackets cast on the sides of the 
 head stocks. They are arranged for quartering either right or left-hand lead, 
 as ordered. 
 
 The boring spindle is of large diameter. A bearing is prox-ided to attach to 
 the front of the face plate to support the end of the spindle, close up to the work. 
 Brackets are also furnished to clarnp the face plates in position wdien quartering.

 Niles Car Wheel Lathe. 
 
 FOR TURNING STEEL TIRED WHEELS. 
 (Patented January ig, i8S6, January 26, 1886. June 2g, 1S86, and April ig, 1S87.) 
 
 Swings 48 Inches, and will Turn Wheels from 33 Inches to 42 hiclies Diameter. 
 
 THIS Lathe is specially clesigned for turning steel tired car and truck wheels 
 on their axles. The ordinary Driving Wheel Lathe is not adapted tor this 
 work as in that case the axles must be supported by their centers. This is 
 not practicable, since in service neither the journals or wheel fits of car axles 
 remain true with the axle center. The problem presented in this case is to grip 
 the axles by their journals, keep them in line with each other and revolve them 
 about their common centers, whether these should be true with the original 
 centers of the axle or not. 
 
 This is accomplished in the following manner : The Lathe is arranged 
 with two face plates revolving on hubs projecting from each head, turned 
 very true and placed in exact alignment. Within these face plates and 
 revolving with them, are placed two very strong, self-centering chucks, 
 with four swivel jaws. They are operated by gearing mounted on each head 
 block. These grip the axle very firmly about the centers of the journals, 
 and with the face plates revolve them in exact line. 
 
 The two face plates are geared together in the same manner as on 
 Driving Wheel Lathes by a heavy forged steel shaft. The driving cone has 
 four steps for a five-inch belt. The gearing Is enormously strong, and all 
 cut from the solid. 
 
 The chucks above mentioned are used only to center the work and 
 insure the wheels being turned true with the journals. The wheels are 
 revolved by two drivers on each face plate, which engage with the heads 
 of the bolts used to secure the tire to the wheel center. These drivers 
 are adjustable both lengthwise and radially to suit any wheel. 
 
 Each head is arranged with a sliding spindle, with centers, which are 
 capped to prevent end motion of the axle when used for turning truck wheels 
 with inside journals. These caps can be removed and the spindles run out 
 beyond the face plates, when the work may be carried on the centers. 
 
 The right-hand head is movable on the bed by rack and pinion. 
 As the chucks have swivel jaws, they will accommodate themselves to the 
 work as it is put into the lathe. 
 
 The feeds are operated from the driving shaft by means of a rock shaft 
 placed in front of the machine, and work through the means of a ratchet lever 
 in the same manner as on Driving Wheel Lathes. 
 
 The front section of the bed is raised, as in the case of Driving Wheel 
 Lathes, and the tool rests are then made short and very stiff. They are 
 adjustable for turning the taper on the tread of the wheel,

 Car Wheel Lathe.— Continued. 
 
 nnHE cut on the opposite page illustrates the novel features of this Lathe. The 
 right-hand head is shown in section, showing the method of gripping the 
 axles on their journals, and the sliding spindle with center, which is capped to 
 tal<e the end thrust of the axle, it also shows clearly the novel dog used for 
 driving. This dog is adjustable in both directions and is easily and quickly set 
 to the work. A circular washer surrounds the bolt head, which is then held in 
 the square socket on the driver. The driver is thus made as short as possible to 
 give rigidity. The journal boxes, as shown, are virtually heavy, four-jawed

 chucks, whose jav/s may be opened and closed while the Lathe is running, from 
 the rtar of the face plates. The chuck jaws have two pads, forming an adjust- 
 able journal box, which can be adjusted with any desired degree of snugness to 
 any axle journal. 
 
 The machine permits of the heaviest possible cuts being taken, and insures 
 that the turned car wheel shall be true with the axle journals. The accuracy 
 secured by this system of operations is inherent in the mechanism, and is not 
 dependent upon the skill with which a workman sets a chuck. This accuracy is 
 not attainable by any other system. 
 
 These Lathes are in successful operation in many of the leading Railroad 
 and Car Shops, and their capacity for work is unequaled.

 Calipering Device. 
 
 FOR NILfcS CAR WHEEL I.ATHE. 
 
 IN turninsj; car wheels it is essential for good work tliat tlie twn wlieels (if a pair 
 sliould he lit equal diameter, and economy forhids the taking of any exti'a cuts 
 over either wheel in order to secure uniform diameter. Fui-thermore, as hoth 
 wheels are tmau'd at one time, the size to which the smallest wheel will finish 
 must he determined hefore the turning reall)' hegins. 
 
 It takes two men to accurately handle the large calipers necessar_\' in car 
 wheel work, and much time is lost in the operation ; and, as a general thing, tlie 
 calipering is done in a \'ery slovenly and inaccurate manner. 
 
 In the pi'eseiit machine a true har is supported, parallel with the axis of the 
 Lathe, in standards upon the two head stocks. This har slides freeh' in its 
 standards, and upon it slides a light, adjustahle spring Caliper. B\' means of this 
 Caliper the smaller wheel can he easily pick'ed out, and then the Caliper can he 
 
 set to a size at which the smaller wheel will finish. The Caliper can then he 
 slid from one wheel to the other and both cuts be quickdy gotten under way. 
 The sliding Caliper is so counterbalanced as naturally to swing upward out of 
 contact with the wheels, but it can easily, at any time, be swept around to bring 
 the point of the Caliper into contact with the work. 
 
 The bar also carries two arms provided with contour rollers which ser\-e in 
 securing the proper gauge for the wheels and in testing the contour of the 
 flange work'. 
 
 The rollers do not serve in any manner as Calipers, but simpK' lie upon the 
 wheels and enable the lathesman to judge at once of where the cutting is to be 
 done. The Caliper slides upon the bar between the arms which carry the rollers, 
 and the free end-shifting ui the bar, together with the sliding of the Caliper upon 
 the bar, enables the Caliper to be freely moved from one wheel to the other. 
 
 The bar, with its Caliper and gauges, is arranged well up and free of the 
 wheels where it does not interfere with the view of the turning tools, and where 
 it does not interfere with the placing of the wheels in and out of the Lathe.

 Double Cutting-Off and Centering Machine. 
 
 FOR LOCOMOTl\'E AND CAR AXLES. 
 
 \ , /ILL cut off and center axles up to 9 inches diameter, and up to 7 feet 6 
 inches in length, cutting off both ends at one time. 
 
 The machine consists essentially of two strong heads mounted on a heavy, 
 stiff bed, along which they are adjustable to suit varying lengths of axles. 
 
 Within these heads are strong chucks which grip the axles firmly. These 
 are driven by spur gear and pinion from below, by a shaft running the whole 
 length of the bed. At each end of the bed are placed the carriages on which 
 are mounted the cutting off slide and centering spindles. These carriages are 
 also adjustable on the bed to suit lengths required. 
 
 The driving cone has four changes for a 4-inch belt. 
 
 The countershaft has a double set of pulleys giving eight changes of speed, 
 so arranged that the speed can be changed instantly as the cutting off tool 
 approaches the center. 
 
 The tool slides have power feed with three changes. The center drills are 
 driven independently. The drill heads are arranged to slide back to give 
 clearance when putting in axles. 
 
 There are countershaft pulleys 20 inches diameter, S^4 inches face, for 
 4-inch belt, which should run 250 and 325 revolutions per minute.

 Liartering Machine. 
 
 FOR QUARTERING AND BORING CRANK PIN HOLES OF LOCOMOTIVE DRIVING WHEELS. 
 
 \ . /ILL quarter wheels ran^inij from 45 inches to 72 inches diameter, and for 
 '' cranks ranging from 16 inclies to 26 inches throw. 
 
 Both crank pin holes are bored at the same time. The spindles are operated 
 from the outside of the wheels and are driven separately. Each spindle has 
 automatic feed, operated by gearing, with three changes. 
 
 The wheels are centered by the spindles, but not supported by them. They 
 are supported on their axles by substantial steady rests, adjustable for height, 
 and are also secured on the tread. 
 
 The spindles may be located on either side of the head stocks, adapting the 
 machine for either right or left-handed lead. 
 
 The machine can be provided with a device for trueing up crank pins in 
 place, when so desired. 
 
 The spindles are driven by belt from overhead countershaft. 
 
 The countershaft has three pulleys 24 inches diameter, for a 3-inch belt. 
 
 Speeds of countershaft, 90 and 120 revolutions per minute. 
 
 A good many railroad shops do all quartering by means of the attachment 
 furnished for that purpose with wheel lathes, but when a large number of engines 
 are to be kept in repair these lathes are kept so constantly employed in boring 
 and turning tires that the use of another machine to do quartering becomes 
 necessary, and this machine has been designed for that purpose. 
 
 It is adapted to be applicable to all the sizes of driving wheels now in 
 common use. The driving axles are securely held in very stiff, adjustable yokes, 
 and are centered by spindles in the head blocks. The wheels are also securely 
 clamped on the tread. Both head blocks are adjustable on the bed, to accommo- 
 date the various lengths of driving axles in use. The boring spindles are placed 
 on brackets on the side of the head blocks. Each head block has two of these 
 brackets placed exactly at right angles to each other, thus allowing wheels to 
 be quartered either right or left-hand lead, as desired. The boring spindles 
 operate from the outside of the wheels, and are entirely independent of each other, 
 so that the stopping of one does not interfere with the other. Three changes of 
 feed are provided — two for roughing and one for finishing. The machine is made 
 in very stiff form, to insure steadiness and accuracy.

 Single Axle Lathe. 
 
 FOR TURNING CAR AND LOCOMOTIVE AXLES. 
 
 r^RIVlNG CONE has three steps for 3>2-incli belt, and is strongly geared. 
 Two changes of feed, suitable for roughing and fuiishing, are provided. 
 The change from roughing to finishing is made instantly, and without tiie 
 necessity of the operator changing his position. 
 
 The face plate carries a self-adjusting driver. 
 
 The front section of the bed is of e.xtra depth, as in the Driving Wheel 
 Lathes, giving additional strength at the point of cut. 
 
 We build this machine mainly for the accommodation of smaller roads 
 and repair shops having but little of this work to do, and we recommend 
 its use in such places only. For shops having a large quantity of this 
 work the Double Axle Lathe is preferred in point of economy. The Double 
 Axle Lathe will do nearly double the amount of work at the same outlay for 
 labor and expense. 
 
 The countershaft is arranged with three pulleys having two speeds, 
 hence giving six changes of speed to the Lathe. 
 
 The countershaft pulleys are 20 inches diameter, 8 inches face. Speeds, 
 90 and 120 revolutions. 
 
 Note.— These machines are furnished either with or without the very convenient crane 
 shown in cut, as desired.

 Double Axle Lathe. 
 
 ( Patented May 9, 1S7T, and Jan. 10, 1882.) 
 
 ""PHIS machine is designed for turning; Locomoti\'e and Car Axles, and is 
 
 provided with two carriages, tool posts, etc., for finishing both ends of the 
 axle at the same time. The axle is passed through the center-head and driven 
 by an equalizing driver, turning upon two dead centers. The axle is finished 
 complete at one operation, without turning end for end. 
 
 The driving cone has three steps for a 4-inch belt, and is very strongly geared. 
 
 Carriages are fed by steel screw with right and left-hand threads. The 
 feeds are driven positively by gearing, and two changes of feed for roughing and 
 finishing are provided without changing gears. The change is made by pulling 
 an internal clutch. 
 
 The center head is movable on the bed. This head carries an equalizing 
 driver plate, the driving studs of which come in contact with the dog on the axle, 
 hence the axle is not held rigidly but is permitted to accommodate itself to any 
 irregularities in the forging. This method of driving, together with the fact that 
 we turn on dead centers, insures the most accurate character of work. The 
 center leg forms a tank for holding water and oil. A rotary pump driven from 
 the main gearing forces a stream of water and oil on the cuts while the machine 
 is in operation. The carriages and bed are so constructed as to carry the overflow 
 back into the tank. 
 
 A convenient crane is provided, by means of which one man can handle the 
 axles in and out of the Lathe. 
 
 The hole through the center head is 8}( inches diameter, hence an axle can 
 be put into the Lathe easily. The Lathe will take in between centers 7 feet 
 8 Inches, accommodating the longest axle in use. 
 
 The capacity of this machine is nearly double that of the best Single Axle 
 Lathe built. From seven to ten axles per day of ten hours is a fair average on a 
 Single Axle Lathe. On our Double Axle Lathe from sixteen to twenty axles can 
 be finished by an average hand as a regular day's work. We have cases where 
 as many as twenty-five axles have been turned in one day. 
 
 This Lathe has demonstrated its value by actual service for many years in 
 the leading railroad and car shops of this country. It is by no means an 
 experiment. It will do the work claimed for it and fully justifies the increased 
 investment. 
 
 The countershaft has two pulleys, 18 inches diameter, 4 inches face, and 
 should run 160 revolutions per minute.

 NILES TOOL Xv'ORKS, HAA\ILTOiN,01-llO. 29 
 
 Car Wheel Boring Machine with Power Crane. 
 
 FOR BORING CAR WHEELS LIP TO 42 INCHES DIAMETER. 
 
 n^HE cliLick is 48 inches diameter, self-centering, vvitli independent jaws. 
 
 For boring car wlieels a very stiff and powerful macliine is required. 
 It is tlie usual practice to take two cuts in boring wheels ; the first, or 
 roughing cut, taking out most of the metal to be removed. The finishing 
 cut is run through at a fast feed, taking out very little metal. This work 
 is forced to the utmost capacity of the tools. It is, therefore, important 
 that the machine should be very stiff and perfectly rigid under the heaviest cuts. 
 
 Our Car Wheel Borer is one of the heaviest machines built for this 
 purpose. Weight, 11,500 pounds. The metal is distributed in the best manner 
 to resist the strains to which such a machine is subjected. 
 
 The column is not square or rectangular in section, but is of such 
 form as to partly surround the chuck plate with a very broad base, 
 being the stiffest form possible, and preventing any spring in the machine. 
 
 The chuck is made very strong and substantial in order to stand the 
 very hard usage to which such a machine is subjected. The chuck'-spindle 
 is fitted to a straight bush in the body of the machine. In case of wear 
 this bush may be replaced and the spindle refitted in any shop. 
 
 The machine is provided with power crane, by means of which wheels 
 may be handled with the greatest ease and very rapidly. The crane beam 
 is very low, and may swing under the tool bar, directly over the center 
 of the chuck. 
 
 The driving cone has three steps for a five-inch belt. 
 
 There are three changes of feed — two for roughing and one for finish- 
 ing — ranging from one-si.xteenth to one-half inch. The change from the 
 roughing to the finishing cut is made by the operator instantly, without 
 changing belts or gears or moving from his place. 
 
 The boring bar is fed by a steel rack, accurately cut. It is counter- 
 weighted and has quick return. 
 
 Countershaft and wrenches are furnished with machine. 
 
 The countershaft pulleys are 30 inches diameter, 6^ inches face. Speed 
 of countershaft, 60 revolutions per minute. Countershaft for crane has 
 pulleys 12 inches diameter, 4}^ inches face. Speed, 200 revolutions.

 Hydrostatic Car and Driving Wheel Presses. 
 
 THESE machines are designed for pressing on and off car and driving wheels 
 by hydrostatic pressure. 
 
 They are all very strongly made and will work with safety up to their stated 
 capacity. The cylinders are all made of cold-blast iron and are lined with copper, 
 which is \-ery carefully spun and burnished into place to prevent leaking. 
 
 On all sizes except No. i the pumps ha\'e two plungers li^ and i inch 
 diameter, respecti\'ely. 
 
 The operation of the plungers is controlled by an improved de\'ice recently 
 brought out by us and patented. This device consists of rods and levers con- 
 nected with the suction valves. By raising the levers the suction valves are 
 seated and the plungers force water into the cylinder. At the start the combined 
 areas of both plungers are thus utilized. When the pressure rises, the rod con- 
 nected with the valve of the larger plunger is dropped, unseating the valve and 
 stopping its operation. The smaller plunger continues its work until the wheel 
 is forced to its position. Its rod is then dropped and the operation ceases. 
 
 The starting and stopping is done instantly, v/ith the least possible exertion 
 on the part of the workman, and without changing his position, and both plungers 
 are utilized at the start to expedite the work. 
 
 The cylinders and resistance posts are held by two heavy, steel tie-bars, 
 amply sufficient for the heaviest duty. A cast iron sole-plate supports the entire 
 machine, making it wholly self-contained. 
 
 We furnish pressure gauge, graduated to show pounds per square inch and 
 tons on ram ; safety valve, enclosed in a case wherein it may be locked ; relief 
 valve, weight for ram, tank and wrenches. 
 
 The pressure ordinarily required for forcing wheels on their axles is about 
 thirty tons, and when put on at that pressure they will not come off in use. For 
 removing old wheels from their axles the pressure required may be equal to all 
 the machine will exert. 
 
 These machines are built of following sizes and capacities. 
 
 No. I Hydrostatic Car Wheel Press. 
 
 FOR PRESSING ON AND OFF CAR WHEELS. 
 
 Will take in wheels up to 36 inches diameter. Tested up to a pressure of 
 100 tons before leaving the works. 
 
 The ram is 8 inches diameter, and has 18 inches stroke. 
 
 The pump has a single plunger, 3<j;-inch diameter. 
 
 The machine has two pulleys 30 inches diameter, 4 inches face. Speed, 100 
 revolutions per minute.

 Gentlemen ;— This company has had one of your Lathes for turning steel-fired wheels in 
 use for three years, and considers it an exceedingly good tool. We turn the tires of from four 
 to six pairs of 36 and 42-inch wheels in ten hours, according to the degree of hardness of the 
 tire. We use this Lathe for preparing new tire for retiring wheels, chucking both tires at the 
 same time. Yours truly, JOHN KIRBY,

 Gentlemen :— We purchased from your company in the summer of 1887 one of your 
 79-inch Double Head Wheel Lathes for turning locomotive tires. This machine was set up and 
 put in use in November, 1887, since which time it has been in constant service. The machine 
 has been kept constantly running during the working hours of each day, and in many cases 
 making over-time at night, and 1 am pleased to say it is the best tool of the kind I have ever had 
 the pleasure of operating, doing its work to our entire satisfaction in every respect.

 Gentlemen; — Your favor of the 3d inst., asking about the working of your Steel-Tired 
 Wheel Lathe now being used at these shops, came safely to hand, and in reply would say that 
 we have often put the tires of a pair of 36-inch wheels in proper shape in just two hours, and at 
 other times we have handled four pairs in ten hours; then again we have only handled three 
 pairs in fen hours. It is all owing to the hardness and condition of the tires, as regards spots 
 that have been slid flat, etc. We do, however, consider your machine the best for the purpose 
 now in existence, and, should we need another, would ask to have this one duplicated. 
 
 Very truly yours, J. W. BAKER,

 Part II. 
 Screw Machines. 
 
 n^HESE machines are invaluable for nialdng set screws, tap screws, studs, and 
 
 doing all descriptions of chasing. A great variety of other work can also be 
 done on them at much less cost than on a lathe. Machines of this class have 
 hitherto been made too light, and only capable of doing the smallest work". 
 
 Where the Screw Machine is known, or where its principle is understood, no 
 words of introduction would be necessary ; but we find so many interested parties 
 to whom this entire subject is new that we have thought proper to treat the 
 matter at some length. We therefore illustrate the machine in general and in 
 detail, also its methods and products. 
 
 The Niles Screw Machine is a lathe with a hollow spindle having a chuck on 
 each end ; a carriage having a hand and power movement, and carrying two 
 tools and a set of open screw-cutting dies ; a sliding tail block having four means 
 of feed, and carrying six tools to be applied to the work successively. 
 
 It will work to advantage on any kind of pieces which can be held in a chuck 
 and which need the successive operation of several different tools. 
 
 The treatment of small work is entirely different from lathe operations. In 
 lathe work a forged shape is trimmed and altered. The Screw Machine takes the 
 rough bar and finishes the product. In this respect the Screv/ Machine represents 
 on its work the black'smith, the helper, the fire, the bolt header, the centering 
 machine, the lathe, the lathe dogs, and the hole in which the lathesman tries his 
 work. It wastes iron, but saves labor of much more value. 
 
 In lathe work a piece may, before being done, go in and out of the lathe 
 man\' times. Dogs are put on and taken off several times. The lathe is stopped 
 many times during changes, and trips are made to the vise or centering machine 
 or blacksmith shop. The Screw Machine presents the end of a rough bar ; the 
 machine starts ; successive tools do their work, and the job is finished before the 
 machine stops or the workman leaves his position. 
 
 We have tested the time on such work in our own shop and found that work 
 requiring thirty hours' time by the lathe plan was done in six and onedialf hours 
 on the Screw Machine. It is enough, however, to say that one Screw Machine 
 will do work which would require three or four small lathes, and that the work is 
 uniform in its excellence.

 and runs in gun metal boxes. The cone pulle)' and back gear is of the full 
 proportion and power of an eighteen-inch lathe. 
 
 C is an ordinary lathe carriage fitted to slide on the bed and be operated by 
 hand wheel D and a rack pinion as usual. 
 
 Across this carriage slides a tool rest E operated b)' screw, and having two 
 tool posts, one to the front and one to the rear of the work. This tool rest, 
 instead of sliding directly in the carriage as is the case with lathes, is mounted 
 on an intermediate block which fits and slides in the carriage. This inter- 
 mediate block is moved in and out, a short distance only, by means of a cam 
 lever G. An apron on the front end of this slide carries the lead screw nut H. 
 When the cam lever is raised it brings the slide outward about half an inch, and the 
 tool rest E comes out with it, and at the same time the nut leaves the lead screw. 
 The inward mo\'ement of the slide is always to the same point, thus engaging 
 the lead screw and resetting the tool. 
 
 With this machine threads ma\' be cut by adjusting a thread tool in the front 
 tool post as in ordinary lathe practice, and at the end of the cut the cam lever 
 serves to quickly withdraw the tool and lead screw nut so the carriage can be 
 run back. The tool rest is then advanced slightly and the new cut taken. By 
 this means threads are cut without any false motions, and max- be cut close 
 up to a shoulder. 
 
 I is the lead screw. This screw does not extend to the head of the machine, 
 but is short and is socketed mto a shaft which runs to the head of the machine 
 and is driven by gearing. The lead screw is thus a plain shaft with a short, 
 removable, threaded end. The gearing is never changed. Different lead screws 
 are used for different threads, thus permitting threads to be cut without running 
 back. The lead screws are changed in an instant by removing knob J. The lead 
 screw nut H is a sectional nut, double-ended, so that each nut will do for two 
 pitches, by turning it end for end in the apron.

 F)G. 3. Plan of Turret. 
 
 The turret slide is moved quickly by hand, by means of the capstan 
 levers U, which, by an in-and-out motion, also serve to lock the turret at any 
 point. The turret slide is fed in heavy work by the hand wheel R on its 
 tail screw. This tail screw carries, inside the hand wheel, two gears S, 
 which are driven at different speeds by a back shaft behind the machine. 
 These two gears are loose on the tail screw, and a clutch operated by lever 
 T locks either one to the screw. Both the carriage and turret are provided 
 with oil pots — not shown in the cuts.

 The Turret Tools. 
 
 w 
 
 E here illustrLite the Jifferent forms of tools used in the turret on ordinary 
 shop work. 
 
 ^ 
 
 Fig. 4- End Gauge 
 
 The End Gauge, shown in Fig. 4, is simph' a hollow shanlc A fitting the 
 turret, and a gauge rod B fitting the shank. The shank may be set further 
 in or out of the turret, and the rod may he set further in or out of the shank. 
 The end gauge is so set that when the turret is clear back against its stop 
 the end of the rod B will gauge the proper projections of the bar iron from 
 the chuck of the machine. 
 
 Fig. 5. Center. 
 
 The Center, shown in Fig. 5, e.xplains itself. Is used only in chasing 
 long work in steel. 
 
 Fig. 6. Turner. 
 
 The Turner, shown in Fig. 6, is a very peculiar tool. It consists of 
 hollow shank A fitting the turret ; a hardened bushing B held in its front end 
 by a set-screw ; a heavy, mortised bolt C in the front lug of the shank ; an 
 end-cutting tool D, shaped like a carpenter's mortising chisel, and clamped by 
 
46 
 
 NILES TOOL WORKS, MAAMLTON. OMIO. 
 
 the iiiortisfd bolt ; a collar screw E to hold the tool endwise, and a pair of 
 set-screws F to swivel the tool and its holt. Bushing B is to suit the work- 
 in hand. The tool L) is a piece of square steel hardened throughout. It is 
 held by its bolt with just the proper clearance on its face. It cuts with its 
 end without an\' springing, and will on this account stand a \'ery keen angle 
 
 Fig. 7. SizER. 
 
 of cutting edge. There is hardly any limit to its cutting power. It will cut 
 an inch bar away at one trip with a coarse feed. It does not do smooth 
 work, and is, therefore, used only to remove the bulk of the metal, leaving 
 the sizer to follow. 
 
 The Sizer, shown in Fig. 7, consists of a hollow shank A fitting the 
 turret and carrying in its front end a hardened bushing B and a flat tool C. 
 
 Fig. 8 Die Holder. Fig. 9, Die Holder. 
 
 The sizer follows the tm'ner and takes a light water or oil cut, giving size 
 and finish with a coarse feed. Having only light, clean work to do it holds 
 its size nicely. 
 
 The Die Holder, shown in Figs. 8 and 9, is arranged to automatically 
 stop cutting when the thread is cut far enough. It will cut a full thread 
 
NILES TOOL WORKS, MAAMLTON.OMIO. 47 
 
 cleanly up against a solid shoulder. !t consists of a hollow shank' A fittinii; 
 the turret ; a slee\-e B fitted to revolve and slide on the front end of the 
 shank C ; a groo\'e E bored inside the sleeve ; a pin D on the shank fitting 
 freely in the groo\'e E ; a keyway F at one point in the groove and leading 
 out each way from it, and a thread die G held in the front end of the sleeve. 
 When the turret is run forward the thread die takes hold of the holt to be 
 cut, but it revolves idly instead of standing still to cut, until the pin D comes 
 opposite the ke)'way F, when the turret still being moved forward the pin 
 enters the back of the keyway. The sleeve now stands still, the die cuts 
 the thread and pulls the turret along by the friction of the pin in the keyway. 
 Finally the turret comes against its front stop and can move forward no 
 further. Consequently the sleeve is drawn forward on its shank C, and the 
 instant the pin D reaches the groove E the die and sleeve commence to 
 revolve with the work and cease cutting. The machine is then run back- 
 ward and the turret moved back a trifle. This causes the pin to catch in the 
 front end of the keyway and the sleeve is again lodged. The die then 
 unscrews, and, in doing so, pushes the turret back. A tap holder may be 
 inserted in place of the die, and plug taps may be run to an exact depth 
 without danger. 
 
 Box Tool. — A box tool is a turret shank arranged to hold a series of 
 cutters so as to produce work of several sizes, shoulders and shapes. Box 
 tools are used only on special manufacturing work, and its construction will 
 readily suggest itself when occasion requires. Fig. 25, on page 49, shows a 
 wrist pin with three sizes. Such a thing, if needed in quantities, would jus- 
 tify the use of a box tool. For ordinary work several sizes are produced by 
 using several separate turret tools like the sizer shown in Fig. 7, the heaviest 
 cut being made by the turner shown in Fig. 6. There is hardly a limit to 
 variety of cutting-tools which may be set in the turret to do the different 
 parts of the work on a piece. Fancy end shapes, etc., as well as different 
 effects on large, flat jobs, all come within the range of the turret operations. 
 
 Drilling. — Drills and other boring tools are held in suitable sockets 
 fitting the turret. 
 
 The Carriage Tools. — The carriage has two tool posts in which are 
 used ordinary lathe tools of various shapes. These two tools are used at 
 different times, and the rear one cuts when the machine is running backward. 
 
48 
 
 NILES TOOL \\'ORKS. f IA,niLTON, OHIO. 
 
 Onf may be used as a rou.uhinu and shapiii,^ tool, and the other used with 
 constantly l<een ed^^e to put on the final finish. Or one may be used to 
 produce a siiape on one part of the job and tile other used to put a different 
 shape en another part. Generally a cuttiii.^-oft" tool is kept in the rear tool 
 post. In working on steel not well annealed it is not well to use dies, etc., 
 which, under such circumstances, quicl<l\' lose their size and k'eeiiness. The 
 front carriai^e tool is used as a chasint^ t(jol on such work in steel. In using 
 the carriage tools no end measurements need be made on the work, as the 
 carriage stop determines the limit of the carriage travel.

 The Open Die Arm. — The open die arm is similar to a bolt cutter head. 
 It is pivoted to the rear of the carriage and is turned forward when in use. 
 It carries a set of open threading dies which can be kept sharp by grinding. 
 The dies are very quickly changed from one size to another. They are 
 re-cut by the hob, shown in Fig. lo, which is held in the chuck and 
 turret center.

 SECOND OPERATION. 
 
 Turret being clear baclv against its stop and 
 revolved to bring present the END GAUGE, the bar 
 is set against tlie end gauge and tlie chuc]< is tight- 
 ened. This chucks the bar and leaves the proper 
 length projecting from the chuck. 
 
 THIRD OPERATION. 
 
 Front tool in the carriage, a beveled side tool, 
 cones the end of the bar so turret tools will 
 start nicely. 
 
 FOURTH OPERATION. 
 
 Turret being revolved to present the TURNER, 
 the bar is reduced at one heavy cut to near the 
 proper size, the turret stop determining the length 
 of the reduced portion. 
 
 FIFTH OPERATION. 
 
 Turret being revolved to present the SiZER, the 
 body of the bolt is brought to e.xact size by a light, 
 quick, sliding cut.

 Tapping Nuts.— In tapping nuts on the Niles Screw Machine the common 
 nut tapping process is followed. The nut tap, shown in Fi-. 32, is clamped in 
 the chuck and the nuts are held with a wrench. When the shank of the tap gets 
 full of nuts the tap is taken out and the nuts removed. If nuts be bought ready 
 
 Fig. 32. Nut Tap. 
 
 tapped, or if there be a tapping machine in the shop, the Screw Machine need 
 not, of course, do this work. There are, however, many special nuts often 
 wanted, and it is well to arrange to make them on this machme. 
 
 Facing Nuts. — Facing nuts on a man- 
 drel between centers in a lathe is a 
 ridiculously slow process, as the mandrel 
 must he removed from the lathe two or 
 three times for each nut. This consumes 
 more time than the facing. It is well 
 known that rough nuts can not be truly 
 faced if strained up against the shoulder 
 of a solid nut mandrel. Figs. 33 show 
 the patent mandrel used by us. The 
 free collar B allows the nut to adjust 
 itself true with its thread. ha facing 
 nuts on the Niles Screw Machine the 
 patent mandrel is clamped in the chuck 
 and both carriage tools are used — the 
 front tool, dressed to the proper curve, 
 doing the rough, heavy work, and the 
 hack tool finishing afterward with a light 
 water cut with the machine running 
 backward. Nuts may be run on and off 
 while the machine is running. We can 
 supply these patent mandrels in sets for 
 use in common lathes. The\' are of steel.

 Range of Turret Operations. 
 
 T 
 
 HE intelligent mechanic, b\- inspecting this machine and analyzing the 
 functions oi the parts and mo\'ements, will quickly understand that in 
 an ordinar\' machine shop there is hardh' a limit to the usefulness of the 
 machine. The name — Screw Machine — is calculated to create an impres- 
 sion that the machine is exclusi\'el\' for screw and bolt work. The name 
 arises from the fact that the turret principle was first employed in machines 
 for making the screws used about sewing machines, etc. In such work 
 these machines ha\'e been carried to a high degree of refinement, often 
 being pro\'ided with wire feed, self-chucking devices, automaticalh' re\'ol\'ing 
 turrets and automatic carriage movements, wherebx' a rod of iron or steel 
 being once chucked and the machine started, the machine needed no further 
 attention till the rod was completel}' worked and a new one required. The 
 automatic movements, quite feasible in these small machines, become 
 impracticable and undesirable when the parts to be moved have great 
 weight and hea\-iness of motion, and when the massi\'e operations are 
 necessarily slow. 
 
 From making screws only the machine ad\'anced into making numerous 
 small parts of sewing machines, guns, etc. Then came the Fox lathe for 
 brass work, without which machine the elegant brass work of to-day 
 would entirely fail in its uniformity of size and finish, and would be 
 increased at least ten-fold in cost. 
 
 Now we find the machines making the heaviest screws, bolts, pins, 
 handles, knobs, nuts, finished washers, rods, plugs, buttons, glands, flanges, 
 followers, arms, collars, and similar lathe work. Numerous kinds of square 
 and irregular castings, held in a suitable shifting chuck, can have a place faced 
 here, a boss turned there, a recess cut, a hole drilled, a hole drilled and 
 counterbored, a hole of one size drilled and tapped here, a hole of another 
 size drilled and tapped there — and all with a cheapness and a uniform 
 accuracy not attainable b)' the most complete outfit of separate machines. 
 These machines are run by unskilled men, the care and setting of the 
 tools, of course, being confided to a skilled man.

 United States Standard Screws. 
 
 "T^HE table on opposite page gives standard sizes for screws, heads and nuts, 
 ^ and we earnestly advise among our patrons its adoption. It is now used by 
 all the first-class shops in the country, and taps and dies are made in accordance 
 with it. The thread is not sharp at top or bottom, but is flattened, as shown in 
 Fig. 34. This thread is most durable, permits best fitting, and the threading tools 
 are durable. Darling, Brown & Sharpe supply gauges for giving shape of tool 
 point. The angle is 60 degrees, and the flats equal one-eighth of the pitch.

 There are no standards for the heads of machine screws, though there should 
 be. We present below a table of sizes as used by us for many years. We know 
 of nothing in its favor except that it is a list which secures uniformity with those 
 who use it, and that it recognizes usual sizes of bar iron.

 Accurate Sizes. 
 
 IN all kinds of shop work it is of yrt-at importance that sizes be uniform and 
 accurate. Setting calipers by a scale will not give an accurate size, and as no 
 two work-men woukl get exactly the same size it follows that there can be no 
 uniformity in the sizes. In our own slKip we use no loose calipers. We use 
 solid gauges, hardened and ground and kept in shape by the tool room men. All 
 the workmen consequently use the same size, and the sizes are as accurate as 
 
 yn 
 
 Fig. 55. OuTSiDii Caliper. 
 
 the tool makers can make them, hi screw and bolt work the matter of sizes is a 
 specially important one, and purchasers of our Screw Machines have generally 
 been supplied by us with standard calipers. 
 
 Fig. 35 shows a standard one-inch solid caliper. It is of steel, hardened and 
 brought to size after hardening. It is accurate to the ten-thousandth part of an 
 inch. It is short and stumpy so as to slip from the fingers if crowded too tightly 
 upon the work. These calipers can be furnished in sets running bv sixteenths. 
 If these outside calipers be true to size the workman can get inside sizes by 
 
 Fig. 36. Inside Caliper, 
 
 setting his calipers to these. But these outside gauges will, of course, lose their 
 size in time by strain. It is, therefore, important to have the accurate size 
 preserved in male form, which is not subject to strains. With an accurate male 
 size the outside calipers ma_\' be easily kept in good shape. 
 
 Fig. 36 sho\\'s a standard one-inch inside caliper, of hardened steel, brought 
 true after hardening, and accurate to the ten-thousandth part of an inch. Such 
 calipers ma\' be put in regular use, or tliey may be carefully preser\'ed as sizing 
 iiauges. We mal<e free use of them in the shop.

 Fi^i. 37 shows a step gauge, intended simply as a corrective gauge for outside 
 calipers. It may be used to adjust tlie solid calipers iTy, or it may be used by 
 workmen to set their common calipers by. It consists of a lot of accurately 
 ground rings, made true to tlie ten-thousandth part of an inch, and strung on a 
 
 k-.

 rod liaving a handle. We can furnish these step gauges got up in most any range 
 of sizes between one-eighth inch and four inches. For Screw Machine work we 
 advise a step gauge one-eighth inch to one inch, running by sixteenths. 
 
 Fig. 38 shows a screw gauge. It consists of a male screw brought true to 
 U.S. standard thread, and a female screw wliich tits it properly and which can be

 kept to size. The female part is grooved so as to yield to adjustment and to clean 
 nicely. These screw gauges are seldom used for regular shop work, but are 
 carefully preserved as a means for keeping the regular tools to size. They are 
 indispensable where a refinement of accuracy is required.

 (P.ilcntcd Marcli 6, 1883.) 
 
 ' I 'HIS machiiu' luis ;ill the requisite vvei<j;ht and power to operate advan- 
 tageously oil work its full swing. The cone has 4 speeds for a belt 
 2_^2 inches wide. The back gearing is strong and powerful. The spindle 
 is steel, and has a hole through it 2J„- inches diameter; the journals are 
 necessarily \'er)' large. 
 
 Every variety of screw, stud, tap bolts, etc., are made on this machine 
 from the solid bar, requiring no forging, centering, or turning, and at a saving 
 of fully fifty per cent, over the ordinary method of making screws. 
 
 The turret head is supplied with all the necessary tools for accomplish- 
 ing the required purposes, such as sizing the work, or turning it standard 
 diameter, pointing it, cupping it, or forming it in any desired uniform shape. 
 The carriage is provided with two tool posts, carrying tools for these 
 different operations. 
 
 Adjustable stops regulate the length of the screw, the length of the 
 head, the length of the thread, etc., with perfect- uniformity. 
 
 Steel leading screws or hobs are furnished for chasing steel or pieces too 
 large for the dies. The movement that engages the nut for screw-cutting 
 also projects the tool, and, consequently, the movement that disengages the 
 nut also withdraws the cutting tool from the thread ; this arrangement 
 dispenses with the necessity of turning the feed screw backward to relieve 
 the tool from the thread ; its movements are always forward in any degree 
 desirable until the job is finished, which insures the greatest certainty in 
 taking the desired amount of cut. 
 
 Tapping and facing nuts can be done rapidly. 
 
 The outfit usually furnished with the machine consists of taps, dies, etc., 
 for cutting from yi, to i inch inclusive, as follows: 
 
 6 Machine Taps. 6 Hobs for Leading Screw Nuts. 
 
 6 Standard Solid Dies. i Opening Die Plate, with 6 sets of Dies. 
 
 6 Hobs for Dies. 2 Cutting Tool Holders, with 6 sets standard 
 
 6 Standard Caliper Gauges. collars each.

 { Patented June 25, iS8q.) 
 
 ' I "HIS is a \-ery hea\'y and pnwcrful machiiif, made fnim new patterns and 
 
 embracing tlie latest patented imprDvenicnts. 
 
 Capacit\-, 55-incli ti) ii-2-inch screws. 
 
 Dies will work up to two inches. With the leaders threads can be cut up to 
 full size of stock the machine will take. 
 
 The spindle is 4^ inches diameter, with a front bearing 6}^ inches long, and 
 has a hole 2|i inches diameter throui_'h it. 
 
 The cone ranges from 14 inches to 7 inches diameter, and has four steps for 
 a T,}4 inch belt. 
 
 Both the cone and face gear are loose on the spindle, and are driven the one 
 by a friction, the other b\' a tooth clutch, connected to a sliding hub splined to 
 the spindle. The friction obviates the shock incident to starting the spindle at a 
 high velocity, as the motion is gradual, while the tooth clutch on the face gear 
 insures steadiness of motion under iieavv strain. 
 
 The manner of mounting the turret and the arrangement of feeds, which 
 have proved so satisfactory in the No. 2 machine, are still retained, v/hile in 
 addition the turret is made to re\'olve and lock automatically. The point at which 
 the revolution of turret takes place is adjustable, and is indicated by a gauge at 
 
 « 
 
 the front of the turret slide. 
 
 The carriage has a power feed operated from the back feed shaft, independent 
 of the motion obtained by the leaders. 
 
 A pump is supplied with each machine which pumps the oil or water from a 
 tank in the bed of the machine, and is provided with a safety valve whereby all 
 e.xcess of oil is returned to the tank, and allows the pump to continue working 
 when the drip cocks at the tools are closed. 
 
 The outfit usually furnished with the machine consists of taps, dies, etc., 
 for cutting from 5,5-inch to 1 j/i inches inclusive, as follinvs; 
 
 8 IVlachine Taps. 8 Hobs for leading screw nuts.

 Gentlemen : — The Screw Machine purchased of you in October, 1886, has proven to be of 
 great value in our work. It has been constantly employed since its purchase, ;uid has been used 
 principally in making stud bolts. We find that we can make from two and one-half to three 
 times as many with this machine as can be made on the ordinary lathe.

 Gentlemen : — Your letter, making inquiries in regard to my experience in the use of your 
 Screw Machine, has been received. We have had one of these machines in constant service for 
 more than three years at our St. Paul shops, and have just received another machine for St. Paul 
 and one for Sioux City, making three machines now at work. 1 consider that each machine 
 will do the work of three scre«--cutting lathes and turn out equally good work. There is a very 
 large range of locomotive work which can be done economically on these machines, such as 
 studs, set screws, and bolts. The fact that we h.ave purchased two additional macliines, after 
 using one for some months, will show you that 1 consider it a very \-aluable tool.

 of the Screw Machine purchased from you. In reply we have to say that we have not had 
 occasion to do .1 great deal of work on this machine since it has been in our possession. Such 
 as we have had, however, justihes us in the assertion that with the proper handling of same by 
 one of our mechanics it will do the work of three or four lathes. The machine is easily 
 manipulated, and gives entire satisfaction. Very respectfully,

 as to the efficiency of your Screw Machine, we are pleased to write you that it is a first-class tool. 
 For the greater part of our work it does the work of from t\vo to three engine lathes. We use it 
 mostly for turning studs and cutting special screws, such as can not be bought from dealers. 
 We would not part with it for a great variety of work.

 Gentlemen: — In answer to yours respecting work we are doing upon the Screw Machine 
 purchased from your works some time back, ^\•ill say this machine will turn out three times as 
 much work as one of the best improved small lathes of the class of work it is intended for. We 
 ha\e used it mostly for all kinds of screw bolts with square or he.xagon heads, or round heads 
 for counter sunk holes. We make all kinds of studs with threads on both ends ; also by using 
 variable dies we make all holts and studs for boiler work requiring steam-tight threads. We 
 also face all sizes of nuts, etc. I consider this machine almost indispensable, and would hardly 
 know how we could get along without it.

 Part III. 
 General Description of Lathes. 
 
 THESE Lathes are all built from new desi;j:ns embodyiii;:^ the latest improve- 
 ments, and all the parts are calculated to withstand the heavy duty imposed 
 by modern machine shop practice. 
 
 The beds are of very large section, strongly cross-girted and braced, and the 
 ways are of extra large proportions to give ample wearing surfaces. 
 
 The head stocks are made of a very strong and rigid f(irm. They are webbed 
 entirely across under the cones both t(j insure stiffness and permit the use of as 
 large driving cones as possible. This form of construction gives the greatest 
 amount of pullint; power possible in the range of the swing. 
 
 The cones are strongly back geared, and the ratio is calculated to give a 
 regular gradation of speed from the slowest to the fastest. They bear their whole 
 length on the spindle. 
 
 The spindles are made of open hearth steel, are of large size and run in 
 composition boxes. They have exceptionally large and long bearings, very 
 accurately fitted. 
 
 The tail stocks have also large spindles and set-over for turning tapers. On 
 the larger sizes they are arranged with rollers mounted on eccentric studs. One 
 turn of the wrench engages the rollers with the bed, and thus the tail stocks can 
 be easily adjusted by one man. The larger sizes have separate holding-bolts for 
 the upper and lower slide, so that the set-over can be adjusted without releasing 
 the tail stock. 
 
 The carriages are made very long and bear their entire length on the ways. 
 They are gibbed front and back and the aprons are very strongly secured to 
 them. The apron gears have large and long bearings thoroughly braced and tied 
 together. The tool rest is so mounted as to be removable, and thus present the 
 entire carriage surface for bolting work. This is an important feature for shops 
 not supplied with regular boring machines. 
 
 All our Lathes up to 36 inches swing have the feeds reversed at the carriage 
 apron. We regard this arrangement more convenient for the ciuick handling 
 required in smaller sizes. The reversing lever is so arranged that when the feed 
 is engaged it is impossible to close the lead screw nut. 
 
 All sizes up to 48 inches swing have two speeds to the change-gear stud, 
 controlled by in-and-out pin, thus giving two feed ratios with every change of 
 gear, both for feeding and screw cutting. 
 
 Each Lathe is provided with compound rest and power cross feed. The 
 cross feed ranges the entire width of the face plate and is as powerful as the 
 longitudinal feed. All Lathes are fitted up in the best possible manner to insure 
 durability of wear under heavy duty. Surfaces are fitted by scraping, no emery 
 being used, and all fits are made to U.S. standard gauges. 
 
 Each Lathe is provided with center and steady rests, large and small face 
 plates, screw gearing, countershaft and wrenches.

 Shafting Lathes. 
 
 THE 26 and 30-inch Lathes are especially recommended for turning shafting. 
 We mak'e two styles of shafting rests for this purpose. One is intended more 
 for occasional use, and has two tools on the front and one at the hack of the rest. 
 The other style, which we furnish for continuous use, consists of a heavy rest 
 base provided with a tank and pump. It has two tools immediately preceding, 
 and one following, the shafting ring. All three are in front. 
 
 Both these rests are equipped with our patent split collars. These are so 
 made that they are perfectly rigid v/hen in place, and yet can be easily inserted 
 when the end of the shaft is turned to receive them, without removing it from 
 the Lathe. 
 
 When desired we arrange these Lathes with a driving gear on the tail stock. 
 This arrangement permits turning a shaft its entire length without removal from 
 the centers.

 6o-Inch Heavy Forge Lathe. 
 
 ' I 'HIS Lathe is built from entirely new patterns, and is made extra 
 
 hea\'\' aiiLJ stnuiL^ tliniu^linut. It is ile'si^ned for Lise in forces for rough 
 turning or finishing liea\\' sliafts, rolls, crank's, etc. ; also for machine shop 
 use when extra dut\' is required, as in turning and boring large steel 
 castings. The' dut\' imposed on machine tools in such cases is enormous, 
 and Latlies of ordinary weight and construction are not able to withstand it. 
 
 The l,athe swings 60 inches over the ways and 46 inches over 
 the carriage. 
 
 With a bed 16 feet long it will tru'n 6 feet between centers. 
 
 The cone is mounted on an independent steel spindle, with a steel 
 pinion gearing into an internal gear on the back' of the face plate. It 
 has fi\'e steps for a 4}^-inch belt, and has two sets of back gears, thus 
 gi\'iiig fifteen changes uf speed to the face plate. These speeds are ail 
 calculated for even gradations, from the slowest to the fastest. 
 
 The main spindle is 10 inches in diameter at the front end, and the 
 bearing is 15 inches long. The face plate is bolted fast to if. 
 
 The carriage is 68 inches long, and is made of a very stiff form. It 
 is accurately fitted to the bed its entire length, and is gibbed both front 
 and back. 
 
 The rest has compound movement, with longitudinal, cross and angular 
 power feed. 
 
 The feed mechanism is made in the very strongest manner, and very 
 rigidly supported in the apron to enable it to withstand the severe duty 
 impijsed. The feed re\'ersal is by strong tumbler gearing in the head, so 
 that no change in the stud gear is needed in cutting either right or 
 left-hand threads. 
 
 The feed reversing lever is very conveniently placed on the front side 
 of the head stock. 
 
 The lead screw is placed well up inider the shears of the bed, and 
 the nut so arranged as to bring the strain on the carriage as direct 
 as possible. 
 
 The tail stock is held down by four bolts, and is also provided with 
 a strong pawl engaging with a rack cast in the bed. This arrangement 
 offers a positive resistance, thus preventing all danger of slipping. The 
 pawl is raised or lowered by a hand knob on the side of the tail stock. 
 
 The upper slide r)f the tail stock is also held independently by four 
 bolts. This arrangement allows the tail stock to be set over for taper

 on small work equally as well as on large, and on a great many pieces of small work which 
 could be handled on the 26-inch Planer, we find we can get better and quicker results by doing 
 them on the large Planer. The wnrm gear on the large Planer is the best plan we know of for 
 obtaining quick and eas\' re\'ersing motion. The Lathe is equal to the Planer in all respects, and 
 we consider the tools first-class, and would not hesitate to recommend and show them to anyone 
 so desiring. Yours truly.

 Part IV. 
 PLANERS. 
 
 GENERAL DESCRIPTION. 
 
 /^UR planers are driven by worm ^earini^ so arran^^ed as to obtain the 
 highest efficiency witli a moderate velocity of the worm. 
 
 The worm rnns constantly in oil. 
 
 More net power is dex'eloped than in a train of spur yearinjj;. This 
 has been repeatedly demonstrated, and can be shown to be true by any 
 test that may be applied. 
 
 Our method of construction — the result of twenty years' experience — 
 has so perfected same that the wear is less than in any other method 
 of driving. 
 
 We fully guarantee these machines. The value of a tool is its capac- 
 ity for work, both quantity and quality. We challenge comparison in 
 these respects. 
 
 The driving shaft is placed in line with the bed, with the view of 
 setting the machine lengthwise of the shop, parallel with the line shaft. 
 
 The table reverses accurately and without shock or jar. On all sizes 
 below 48 inches the table reverses at a speed of 4 to i. 
 
 All the gearing and rack teeth are accurately cut from the solid. 
 
 The shafts are steel forgings of large diameter, with large and long 
 bearings. The driving shaft runs in bearings of best wearing composition 
 of copper and tin. 
 
 The driving pulleys are of large diameter, exercise great power and 
 allow the table to be reversed in a very short distance. 
 
 The belts are shifted by our patent automatic belt shifter, which 
 transfers but one belt at a time, preventing two belts running in opposite 
 directions from being on the tight pulley at the same time. It is entirely 
 disconnected from the feeding apparatus, therefore works easily and gives 
 the operator quick and easy control over the motion of the table without 
 using the countershaft shipper. 
 
NILES TOOL WORKS, MAMILTON.OMIO. 89 
 
 The driving pulleys and gearing are placed on the side of the machine 
 opposite the operator, being entirely out of the way but still completely 
 under his control when standing in his usual position. 
 
 The loose pulleys are bushed with brass. 
 
 The bed is thoroughly braced by box girders throughout its entire 
 length. Between the housings it is tied together in box form, making it 
 particularly stiff at the point of greatest strain. 
 
 The housings extend well bacf; ; are of the box form ; are strongly 
 braced and rigidly secured to the bed. 
 
 The cross rail is cored out in the form of a box girder, and is very 
 deep and stiff. When t\\'0 saddles are used the cross rail is extended so 
 that one head can be run over entirely out of the way, and the other 
 head have sufficient traverse to plane off the entire width of the machine. 
 
 The top brace is also very deep and stiff, and rigidly secured to 
 the housings. 
 
 The amount of metal is ample and is so distributed as to give rigidity 
 and durability under severe service. 
 
 The feeds are automatic in all directions. They are operated by our 
 patented feeding device, which renders them absolutely POSITIVE. There 
 is no friction to slip or stick. This feeding device, the result of long 
 experiment, is especially valuable with quick-return planers, and when 
 the machine is equipped with several heads, as then the inertia, due to 
 heavy weights and large fractional surfaces, must be overcome in a very 
 short period of time. ANY friction feeding device which is powerful enough 
 to move four heads over a wide finishing cut, under such conditions, is 
 attended with a great loss of power during the time it is inoperative. 
 
 The table is very stiff. The V's are wide apart and large. Table is 
 oiled automatically by counterbalanced rollers in the bed.

 SPECIAL PLANERS. 
 
 36-Inch Frog and Switch Planing Machine. 
 
 TO PLANE 36 INCHES WIDE BY )6 INCHliS HIGH. WITH ADJUSTABLE CROSS RAIL. OR, TO PLANE 
 36 INCHES WIDE BY 12 INCHES HIGH, WITH FIXED CROSS RAIL. 
 
 "T^HE special features of this macliine are its immense vveiglit and power. 
 
 The duty required is very heavy, and Planers as ordinarily constructed 
 have neither the necessary power to carry the cuts nor the strength to stand 
 the work, and, consequently, when used for this service the cost of the work- 
 is very great and the machines themselves soon go to pieces. Our Planer, 
 built specially for this purpose, has enormous power — sufficient to carry two 
 cuts on steel rails, i^^ inches wide, with ys-'mch feed, and all the parts 
 of the machine are made with a margin of strength to withstand this 
 enormous duty. 
 
 Driving pulleys are 36 inches diameter, and run at a speed to give the 
 belts a velocity of 100 to i of the table. The driving belt is 4 inches 
 wide, the returning belt 3 inches. The driving belts transmit power through 
 heavy cut gearing. 
 
 The rack, bull wheel and pinion are 7)4 inches face, 2}4 inches pitch. 
 The bull wheel and pinion are of steel. 
 
 The driving shafts are heavy steel forgings, running in bushed bearings, 
 which may be easily replaced in case of wear. 
 
 The table is made very thick and heavy, running in deep ways in the 
 bed so as to resist the pressure of a side cut. The ways are arranged with 
 improved oilers so as to distribute the oil uniformly. 
 
 The cross rail and heads are made of great size and strength. It is 
 desirable to have as few parts as possible so as to avoid lost motion, and 
 hence no swings are employed, the tool boxes being set directly on the 
 saddles. Power cross and vertical feeds are provided. 
 
 When this machine is to be used exclusively on rails for switches we 
 make it with low housings, bringing the rail within 12 inches of the table, 
 and it is fixed in one position. If, however, it is desired to use the machine 
 for other work as well, the housings are made to take in work 36 inches 
 square, and the rail raises and lowers as on ordinary planers. 
 
 Countershaft pulleys are 20 inches diameter, 6 inches face. 
 
 Speed, 280 revolutions per minute.

 SPECIAL PLANERS. 
 
 No. I Plate Planing Machine. 
 
 WILL PLANE PLATES OF ANY LENGTH. 
 
 r^ESlGNED tor planing boiler plates. Will bevel the edge and square up a 
 narrow caulking surface. 
 
 This machine will do much better work than can be done by hand, and in 
 much less time, and consequently at much less cost. 
 
 The work when done has a smooth, even and true finish. This machine 
 will plane plates 14 to 18 feet long at one setting, and is arranged to plane 
 any length by re-setting the sheet. 
 
 There are two separate tools on the tool post, arranged for easy and 
 independent adjustment. The cut is taken both forward and back, so that no 
 time is lost in reversing. A large steel screw operates the saddle. 
 
 Brack'ets e.xtend out from the back of the bed carrying rollers for supporting 
 the sheet and facilitating handling. A heavy clamping bar holds the plate 
 securely in position. The bar is raised and lowered by screws at each end. 
 No intermediate screws are required, hence the operation of setting is 
 quickly accomplished. 
 
 The machine illustrated is of great strength and power. The driving 
 pulleys are 24 inches diameter for a 2}4-mch belt, and strongly geared to the 
 screw. The screw is of steel, 3;4 inches diameter, 2 inches pitch, and is 
 supported in a continuous bearing, preventing sag or deflection, so injurious to 
 both screw and nut. The nut is of e.xtra length and surrounds three-fourths 
 the diameter of the screw, giving ample wearing surface. 
 
 The countershaft pulleys are 24 inches diameter, 33^ inches face. 
 
 Speed, 300 revolutions per minute. 
 
 The machine as illustrated is arranged with a compound t(jol rest for 
 planing lap-joint work, as required b)' safe and vault makers. This feature 
 is only furnished on special order. Ordinarily the machine is furnished with 
 an inclined rest only.

 SPECIAL PLANERS. 
 
 No. 4 Plate Planing Machine. 
 
 FOR PLANING SHIP AND BOILER PLATES. 
 
 'T'HIS machine will plane plate iron up to 2 inches thick and 20 teet 
 
 long at one setting. 
 
 The tool carriage is driven by a heavy steel screw 414 inches diam- 
 eter, working in a bronze nut 18 inches long. The carriage has a bearing 
 on the bed 28 inches wide by 56 inches long. The screw is supported 
 in a long trough in the center of the bed, preventing sag or deflection 
 and keeping it well oiled. 
 
 The tool head has two tools for planing the edges and one tool for 
 planing the upper surface of the plate. Each tool has independent adjustment. 
 
 The carriage is reversed automatically, and the cut is taken on 
 both strokes. 
 
 The plate is secured to a substantial table, carried on brackets from 
 the bed. 
 
 The entire machine is built in the strongest and most substantial 
 manner. The power of the machine is very great, adapting it to the 
 heaviest service in ship yards and boiler works. 
 
 All bearings are of unusual size. Sliding surfaces are carefully fitted 
 by scraping. 
 
 The countershaft pulleys are 24 inches diameter, 6 inches face, for a 
 5-inch belt. 
 
 Speed, 240 revolutions per minute.

 Double Plate Planing Machine. 
 
 THIS machine is designed tt) plane on two adjoining edges of plates at tiie 
 same time. 
 
 When plates are to be squared or planed to t>evei shapes it is of great conve- 
 nience to be able to do this at one setting of the plate, hi the single plate planers, 
 when work is to be planed on the end, the plate must be set by reference to the 
 edge of the table. If the sheet is long and narrow, and is to be planed to any 
 other angle than 90°, the setting becomes a difficult matter if any degree of 
 precision is required. 
 
 These dii^iculties are obviated by the use of Double Plate Planers, and at the 
 same time the work is performed both quicker and better. 
 
 The front, or long side, of this machine is similar in construction to the single 
 machines. It has a tool carriage 54 inches long, driven by a heavy steel screw, 
 and carries two tool heads for cutting in both directions. One of these heads has 
 compound and angular movement, as in ordinary planers, while the other has 
 horizontal movement only. 
 
 The end bed is pivoted at the right-hand of the front bed. It is clamped to 
 a heavy T- slotted sole plate, and can be adjusted 10 degrees either way from a 
 right angle by means of a rack and pinion. In this movement the bed carries 
 with it a T- slotted table for holding and clamping tlie end of the plate. The tool 
 carriage is driven independently in the same manner as the front one. It has one 
 tool head only, with compound and angular adjustment. It cuts in one direction 
 only and has quick return. 
 
 The clamping bar is a heavy bo.x girder rigidly secured to box housings bolted 
 to the long bed. The housings are overhanging, so that plates of any length 
 may be planed by resetting. 
 
 The clamping bar is placed at sufficient height to clear the end tool slide, and 
 the work is held by screw jacks. 
 
 A wide T- slotted table is placed at the back of the machine, suitable for 
 holding large plates without the aid of auxiliary tables. 
 
 Each tool carriage is driven and operated independently, except that a safety 
 belt-shipping device is provided, by means of which the front tool carriage 
 reverses the motion of the end carriage whenever there is danger of a collision 
 between them. 
 
 Two countershafts are provided, with pulleys 24 inches diameter, 4 inches 
 face. They should run 300 revolutions per minute.

 (jcntlenieii : — Yours of the 26th at hand. In answer would say that if our e.xperience with 
 tile number of tools we ha\-e already received from you did not convince us that we will have 
 nil trouble with the lo-foot Planer, we should certainly want you to send a man to superintend 
 Its erection ; but we anticipate no trouble whate\'er. The manner in which your tools go together 
 and start off to their work, as compared to some others we have, is a miracle. We made a 
 mistake in not getting more of your tools and less of other makes. Shall probably order of you 
 a No. I Horizontal iVlill. Yours very truly, E. V. CLEMENS,

 Gentlemen :— Referring to your \'alued fa\-or of a recent date, I beg to ad\'ise that I am 
 especially well pleased with the 60-inch Planer purchased from your works last \'ear. The 
 machine being heavy, substantial and well proportioned in all its parts, and designed to stand 
 the heaviest class of work, has given entire satisfaction and I take pleasure in so advising you.

 Niles Tool Works, Hamilton, O. FT. WAYNE, IND., May i, 1890. 
 
 Gentlemen ;— We take pleasure in testifying to the merits of the new machinery we 
 purchased of you some time since — particularly the 8.x8-foot Planer and the 16-foot Boring and 
 Turning Mill, both of which are e.xceptionally good tools and entirely satisfactory to us. 
 
 The method of driving the Planer by tangent gearing imparts a \-ery smooth motion to the 
 table, and judging from our e.xperience of eighteen months — during which time the machine has 
 been in constant use — we see no reason to question its durability. We have made a number of 
 special machines ourselves driven in this manner, and our conclusion Is that when properly 
 proportioned and constructed, tangent gearing is a very e.xcellent and durable method of driving.

 Gentlemen :— Replying to yours of the 23d inst., relative to the special Planer for frog and 
 switch work, allow me to say that some five years ago we felt the need of a special tool for 
 planing rails used in split switches, and after due consideration of what was required an order 
 was placed with you for this tool. I am free to say that this tool has, and is, doing excellent 
 service, planing two rails at one and the same time, reducing flange and head of rail at one cut. 
 It has proven to be one of, if not the best machine for the purpose I have seen, and would 
 recommend it to any one needing such a tool. We have since put in more of your Planers and 
 many other tools of your make. All are doing good work. Hoping the above will be of service,

 months ago, we are pleased to report it entirely satisfactory in every particular. We have been 
 working it night and day on heavy work, constantly, since December ist. It stands up to it 
 handsomely, is very massive and powerful, and has done a vast amount of excellent work since 
 we have had it. Very respectfully yours,

 Gentlemen : — We ha\'e in use two of your Planers, a 36x36-inch 12-foot, and a 44x44-inch 
 12-foot, the latter with a side head. These Planers are both giving excellent satisfaction. Thev 
 run smoothly under heavy loads and heavy cuts, reverse noiselessly and without shock. They 
 are well built, and much heavier in all their parts than same size Planers of other makes. We 
 can cheerfully endorse all you claim for them. 
 
 Yours respectfully.

 Gentlemen : — We have now thoroughly tested the Iron Planer, 5,\ 5.x 16-foot, and the 6-foot 
 Boring and Turning Mill bought of you last year, and fnid them satisfactory in every respect. 
 Their efficiency has reduced the cost to us of the work that we bought them to do. The 
 design of the machines spoken of shows careful thought and experience as to what is required of 
 such tools. The Horizontal Boring Machine bought of you, standing beside others of same 
 kind, receives the preference by our machinists. 
 
 Yours very truly, FRANK S. MANTON,

 Gentlemen :— We purchased from you, in 18S6, a 6o.\6o-inch 16-foot Niles Planer, which 
 has been almost continuously in use since. The first piece planed on same weighed 25,380 lbs. 
 net. The Planer was belted on Saturday at 3 o'clock, and on Monday morning a piece was 
 placed on same and ran si.x days without running off of table for oiling ways, which we considered 
 at the time a very severe test for the Planer. There was no sign of cutting whatever. We con- 
 sider it the best tool made as yet, both as to oiling of table ways and the mode of gearing table 
 to develop power. Yours trulv,

 Gentlemen: — In reply to your letter of Oct. 20th, asking me how the new tools are working 
 that your company furnished for the Hnwell shops o\'er a year ago, I have this to say : They 
 are all giving entire satisfaction. The 32-inch lo-foot Planer is well adapted to all classes of 
 work, the patent gear and quick return making it a very valuable machine. The work turned 
 out by this machine can not be beat, and 1 consider it one of the best Planers in use. The 5-foot 
 Radial Drill Press is also giving excellent satisfaction. It is adapted to a wide range of work, 
 and if once used cannot be dispensed with. The 14-inch Slotter, the 72-inch Boring JVlill and the 
 30-inch Engine Lathe are all doing e.xcellent work. They ha\-e been in steady use over twelve 
 months and have given us no trouble whatever. The workmanship and material used in these 
 tools is the best, and they are well-proportioned, which makes them, in my opinion, the best 
 machines I have used. Yours truly, THOS. WALSH, 
 
 Master Mechanic.

 Gentlemen ; — We ha\'e had in constant use for the past five years one of your 48x48-inch 
 T8-foot Planers. IWost of the time it has been running night and day and has been crowded to 
 the utmost. We have used it planing Corliss engine frames, under the heaviest loads and the 
 se\'erest strains. It has stood up to its work magnificently, taking heavy cuts, running smoothly 
 and costing nothing for repairs. Some time after purchasing this Planer we put in a 36-inch 
 geared Planer on the score of economy. This Planer can not in any \\-ay be compared with the 
 " Niles." It is lacking in po\\er, is \'ery noisy, re\'erses \\ith a shock almost sufficient to loosen 
 the clamps, and is constantly breaking down. We would have saved the difference in price 
 many times over had we bought a "Niles" Planer. One year ago we put in an 84x84-inch 
 20-foot " Niles " Planer with four heads. This is doing equally good work. We regard the 
 worm gearing used on your Planers as their best feature, and we believe it is the only way to 
 drive a Planer to get the best results. Yours truly,

 Shaping Machines. 
 
 f\ SHAPING Machine is now considered an indispensable machine in any shop. 
 
 It is invaluable tor a great variety ot work, is almost universal in its appli- 
 cation, and affords an immense saving in the time and cost of doing work. The 
 style of its construction is such that it requires the most accurate workmanship. 
 Many of these machines are very light and incapable of doing anything hut the 
 lightest class of work. 
 
 Our machines are all traveling head machines — that is, the saddle carrxdng 
 the cutter bar is traversed on a bed of considerable length, the cutting tool 
 operating at all points. This type of machine is adapted to a much wider range 
 of work than the Pillar Shaper with stationary head. 
 
 The cutter bar is operated with Whitworth quick' return. This arrangement, 
 first brought out by Sir Joseph Whitworth, of Manchester, England, is generally 
 recognized as being the best movement for tools of this class. In our machines 
 it is so arranged that the forward or cutting stroke takes about two-thirds of the 
 crank motion, while the return stroke is made during the remaining third. The 
 regulation of the speed of the cutter bar is obtained by large cones for wide belts, 
 so proportioned as to give the right speed for long or short cuts, or different 
 material, and with ample power to do heavy work. On the long stroke machines 
 the driving cones are back geared, giving eight changes of speed. The feeds are 
 cross, down, angular, and circular for convex and concave. 
 
 Two tables are furnished with all our machines. On one of them work may 
 be clamped on the top or either side, while the other is arranged to receive a vise, 
 index centers, or a swiveling table. Both these tables have independent ele\'ating 
 screws, which are so geared that they can be easily raised or lowered without 
 stooping. A cone mandrel is also provided for planing such work' as hubs of 
 cranks or rocker arms. These machines are necessarily more expensi\'e than 
 machines with stationary heads, but the advantages of this style of construction 
 far overbalance the increased cost. 
 
 These machines are built in the following sizes : 16, 20 and 24-inch.

 THE cutting bar has i6>< inches stroke and quicl<-return movement. It is 36 
 inches long, and has hearing on the saddle plate ot 26x7>^ inches. 
 
 The saddle has a traverse ot 48 inches on the bed, which is 6 feet long. 
 Saddle can be quickly moved on bed by rack and pinion. 
 
 The feeds are cross, down, angular, and circular for both convex and concave. 
 The first and last are by power, the down and angular feeds by hand. 
 
 The two tables have independent elevating screws, and the arrangement is 
 such that they can be raised and lowered without stooping. They have a vertical 
 adjustment of 18 inches. 
 
 The machine is supplied with swivel vise, centers, self-feeding cone mandrel 
 for circular work, countershaft, wrenches, etc. 
 
 All sliding surfaces are fitted by scraping, no emery being used under any 
 circumstances. All work done in strict conformity with U.S. standard gauges. 
 
 The countershaft has tight and loose pulleys 16 inches diameter, 5 inches 
 face. It should run 150 revolutions. 
 
 1 8-Inch Shaping Machine. 
 
 WITH TRAVELING HEAD. 
 
 THE cutting bar has 18^4 inches stroke and quick-return movement. It is 45 
 inches long, and has bearing on the saddle plate of 29x7^ inches. 
 
 The saddle has 60 inches traverse on the bed, which is 6 feet 10 inches long. 
 It is moved along the bed by rack and pinion. 
 
 The driving cone has four steps for a belt 3 J^ inches wide. The cone steps 
 range in diameter from 22 to 10 inches. Two sets of pulleys are provided on the 
 countershaft, giving it two speeds. We have, therefore, eight changes of speed 
 for the cutting bar. 
 
 The feeds are cross, down, angular, and circular for convex or concave work, 
 all operated by power. 
 
 The two tables have independent elevating screws, and the arrangement is 
 such that they can be raised or lowered without stooping. They have a vertical

 The machine is supplied with swivel vise, centers, self-feeding cone mandrel 
 for circular work, countershaft, wrenches, etc. 
 
 All sliding surfaces are fitted by scraping, no emery being used under any 
 circumstances. All work is done in strict conformity with U.S. standard gauges. 
 
 The bed is made unusually deep to give a good bearing to the table saddles. 
 
 The machine throughout is heavy and powerful. 
 
 The countershaft has three pulleys 22 inches diameter, 8 inches face. Speeds 
 of countershaft, 90 and 120 revolutions per minute.

 24-Inch Shaping Machine. 
 
 WITH TRAVELING HEAD. 
 
 THE cutter bar has 24 inches stroke. It is operatfd l^v a variable crank, with 
 Whitworth quick-return motion. 
 
 The bed is 8 feet 4 inches long. The saddle has 70 inches traverse on the 
 bed, with quick motion by power. 
 
 The cutter bar is 63 inches long, and has a bearing on the saddle of 9x37 
 inches. The bar has its full bearing at any length of stroke. 
 
 The feeds are automatic in all directions, for straight, vertical, angular, and 
 circular or curved work. The head has segment wheel and worm. 
 
 The driving cone has four steps, and is strongly back geared, giving eight 
 changes of speed. 
 
 A heavy plate, planed true and T- slotted, covers the entire front of 
 the machine. 
 
 The tables may readily be removed, and large, unwieldy work bolted fast to 
 the face of the machine. 
 
 The tables have a vertical adjustment of 21 inches. They have independent 
 elevating screws, and the arrangement is such that they can be raised or lowered 
 without stooping. 
 
 The machine is supplied with swivel vise, centers, two tables, self-feeding 
 cone mandrel for circular work, countershaft, wrenches, etc. 
 
 The countershaft has two pulleys 14 inches diameter, 4 inches face. Speed 
 of countershaft, 200 revolutions. 
 
 This machine is especially heavy and powerful — without doubt the heaviest 
 and most powerful Shaping Machine built in this country. 
 
 The cutter bar is made very stiff, and with a very long bearing, and is 
 capable of taking a heavy cut at its extreme stroke. 
 
 A great variety of work too large for an ordinary Shaper can be planed to 
 much better advantage than on a planing machine, and at a great saving of time. 
 
 For railroad and locomotive work the machine is particularly valuable. 
 
14-lNCH Slotting Machine. 
 
NILES TOOL WORKS, HAMILTON, OMIO. 1 1 5 
 
 Slotting Machines. 
 
 'T~'HESE Slotting Machines arc built from new and improved patterns, and are 
 
 of the most modern construction. Special reference has been paid in their 
 design to great strength, power and convenience of operation. 
 
 The cutter bar is operated by means of the Whitworth motion, in the same 
 manner as our Shaping Machines, giving a slow motion under the cut and a quick- 
 return. The cutter bar is also counterweighted, which entirely prevents any jar 
 in running. 
 
 Within their rated limit these machines are adjustable in length of strok-e 
 and also in position of the cutter bar, so as to suit work' of different height, and 
 they are also provided with long bearing slides which are adjustable vertically. 
 By this means the cutter bar is always supported close to the work, which mak-es 
 it very stiff and free from any tendency to spring. This is a very important 
 feature, as in many classes of work the adjustable slide made be let down close 
 to the table behind the work, and the cutter so arranged on the bar that it may 
 be supported its entire strok'e. When working under such conditions the machine 
 is as effective as a powerful planer. 
 
 The actual stroke of these machines is enough greater than the rated strol<e 
 to allow for the operation of the feed, so that the full rated stroke of the machine 
 is always available for work. 
 
 The tables have compound movement, with power feed in either direction. 
 They have also a circular table which is fed automatically by tangent gearing. 
 The circular table is arranged to be clamped when feeding by either of the 
 compound movements. 
 
 The feeds invariably take place at the upper end of the stroke- — never 
 during the cut. 
 
 The handles for operating the feeds are all placed close together so that the 
 operator can handle any of them from the same position. He can, also, at the 
 same time watch the cutting tool. 
 
 The general construction of these machines is such as to insure stabilit}-. In 
 addition to this the convenience of handling enables the operator to get out the 
 great amount of work of which such tools are capable. 
 
 They are built in the following sizes: 6%, 10, 14, 18 and 30-inch. 
 
 Heavy geared Slotters are built of the following sizes: 24 and 54-inch.

 THE cutter bar has 26 inches stroke. 
 The machine will take in work 7 feet 6 inches diameter. 
 
 Diameter of circular table, 50 inches. Longitudinal traverse of table, 40 
 inches. Transverse, traverse, 36 inches. 
 
 The driving pulleys are 30 inches diameter for 3-inch belt. 
 
 The countershaft pulleys are 22 inches diameter, 5 inches face. 
 
 This machine is unexcelled for slotting heavy engine cranks, shaping bases, 
 trimming working beams, and all kindred work in steam forges. It is also the 
 most economical machine to use in shops where heavy steel castings are 
 extensively used. 
 
 This and the succeeding 54-inch machine bear the same relation to the 
 slotting tools that the Heavy Forge Lathes and Planers do in their class. They 
 are much heavier and stiffer in construction, and are calculated to withstand much 
 more duty than machine shop slotters as ordinarily constructed. Notwithstanding 
 their weight and power these machint-s are very readily handled, as all their 
 movements are quickly controlled. 
 
 This machine is a very strongly geared tool. The cutter bar is driven by 
 rack and pinion operated by tangent gearing, adapting it to very heavy cutting. 
 It is counterweighted and has quick return, and is also provided with an improved 
 relief motion. 
 
 The actual stroke of the bar is 50 inches, and it will operate on outside work 
 of nearly that length. On inside work, placed below the ram guide, it will give 
 the rated stroke of 24 inches. 
 
 The feeds are self-acting in all directions, and are readily adjusted and 
 arranged so that the feed always takes place at the upper end of the stroke — 
 never during the cut. 
 
 The cutter bar has a very long bearing which is adjustable vertically. This 
 bearing may be raised or lowered to suit the work being operated upon. By this 
 means the cutter bar is always supported close to the work, which makes it very 
 stiff and free from any tendency to spring. 
 
 All the gearing is accurately cut from the solid.

 This is a machine of immense strength and power. The cutter bar is driven 
 by rack and pinion, adapting it for heavy cutting. The machine has sufficient 
 power to take a 3-inch cut with yL-inch feed. The cutter bar is counterweighted 
 and has quick return. 
 
 The rated stroke of the machine is 54 inches, but on outside work, which 
 can be placed in front of the cutter bar, a cut nearly 9 feet in length may 
 be taken. 
 
 The feeds are self-acting in all directions and are readily adjusted. The feed 
 is operated at the upper end of the stroke — never during the cut. 
 
 The tables have compound movement. They are moved by power in any 
 direction, consequently they may be handled as easily as the tables of the 
 smallest machines. 
 
 The cutter bar has a very long bearing, which is adjustable vertically. This

 Gentlemen : — Replying to your esteemed inquiry of the 8th inst., as to what we think 
 concerning the 24-inch Slotting Machine which you furnished us about three years ago, we are 
 pleased to say that the machine has been in constant operation almost from the day of its arrival 
 at our works, much of the time running over-time, and during the entire period it has given us 
 the greatest possible satisfaction. For strength, durability, speed of cutting, and, in fact, in all 
 other important particulars we consider it fully equal, if not superior, to any other tool of its 
 kind in the shop. Very respectfully yours,

 Part VI. 
 
 Boring and Turning Mills. 
 
 ""pHE illustrations on opposite and succeeding pages represent our latest improved 
 Boring and Turning Mills, the design and construction of which are the 
 
 result of an experience probably far greater than that of any other builder of 
 
 Machine Tools. 
 
 In its present state of perfection, the Boring Mill possesses several important 
 
 ad\'antages over the lathe for many classes of work. These advantages are as 
 
 follows : 
 
 1. That its work-table is supported by the bed at its perimeter as well as at 
 its center, whereas in a lathe the weight of the chuck plate, as well as that of 
 the work', overhangs a journal of comparatively small diameter, and is therefore, 
 more subject to spring, deflection and vibration. 
 
 2. It will carry two slide rests more readily adjustable to an angle, and more 
 easily operated than a lathe slide rest. 
 
 3. It is much more easy to chuck work on a boring mill table than on a lathe 
 ■chuck, because on the former the work is more readily placed upon the table, and 
 rests upon it so that in wedging up or setting any part of the work circumference 
 to the table, there is no liability to move the work at the other points of support 
 upon the table ; whereas in a lathe, the work standing vertical, is apt, when moving 
 it at one part to set it, to move at another part and become unset, and further- 
 more requires to be held and steadied while first being gripped by the chuckincr 
 dogs, plates, or other holding devices. 
 
 The great range of work that a Boring and Turning Mill is capable of per- 
 forming is not fully appreciated by some who are not sufficiently familiar with 
 its uses. Many are deterred from considering the purchase of these machines, 
 looking upon them as involving a heavy investment upon a tool not often used. As 
 a matter of fact, the Boring Mill never stands still. A twelve-foot mill will work 
 on small work, of the kind to which it is adapted, to such an advantage over a lathe 
 as to justify its use, regardless of the large work of which it is capable. Numerous 
 small pieces, bolted to its remarkably convenient table, can be simultaneously 
 faced off with a facility not to be found in lathes, planers, or shaping machines. 
 
128 N1L[:S TOOL \\'ORKS, [IA-niLTON,01llO. 
 
 Almost anytliiny; tliat a hithe can do, and much that it can not do, can he done 
 on these improved Boring Mills, and usually in much shorter time and in a nKjre 
 satisfactory manner. The time gained in the mere matter of setting unwieldy and 
 irregularly shaped pieces will alone foot up to a handsome profit \n favor of these 
 machines. Every machinist is acquainted with the annoyance of fastening work 
 of this class to a vertical face-plate, and, should an account of this expense (from 
 loss of time and extra help) be kept, it would even then far exceed the usual 
 estimate. 
 
 These machines can be operated with peculiar facility. The rail is raised and 
 lowered by power ; the tools have quick hand motions ; both tools are operated 
 from one side, and much running about is thus avoided; the machine is better adapted 
 to the use of two tools than a lathe ; the adjustment of both tools is easily effected, 
 and both tools are in full view of the operator. 
 
 The machines built by us, have, by reason of their excellence in all respects, 
 gained for themselves a most enviable reputation throughout the world. They 
 possess every improvement that a long experience in their manufacture could 
 suggest, and they are confidently offered as the most complete machines of their 
 kind ever made. 
 
 When these machines are supplied with our pulley turning attachments they 
 are capable of results in the pulley turning line that are almost past credence. 
 Some of the letters from users, found elsewhere herein, will indicate the 
 nature of some of these remarkable performances. 
 
 The five, six and seven-foot machines answer admirably for railroad machine 
 shops and car builders. When designed for this special duty, and provided with 
 universal chuck and crane, they will bore from sixty to seventy-five car wheels 
 in ten hours, and are eminently suited to boring chills and doing other work 
 about such establishments. 
 
 Improvements have been made by us in these machines to meet the greatly 
 extended use of Boring and Turning Mills. We have hundreds of them in use 
 in the leading shops of this country and Europe. 
 
 In fact, no shop is now considered well equipped without such a machine.

 Niles Boring and Turning Mills. 
 
 SECTIONAL VIEW OF 12-FOOT BORING MILL. 
 
 GENERAL DESCRIPTION. 
 
 J~\RIVING Gear. — The table is driven by an accurately cut internal spur gear. 
 The cone transmits power to a pair of heavy, cut bevel-gears, thence to 
 a steel pinion driving the internal spur on the table. This construction insures 
 a steady running machine without chatter, and free from any lifting tendency. 
 
 Spindle. — The spindle is of great length, with very liberal bearings. It rests 
 below on a steel step. The spindle bearing has ample provision for taking 
 up wear, and this adjustment is arranged to keep the spindle central. 
 
 Cone. — The driving cone is placed at the side of the machine, and the belts are 
 as convenient as on a lathe. Each Mill is strongly back geared, givintr a 
 wide range of speeds. 
 
I30 NILES TOOL \v'ORKS, HAMILTON, OHIO. 
 
 Table Bearing. — An annular bearing under tht- outer edi^e of the table is 
 pni\'ided, and when hea\'\' pieces are to be worl<ed tlie spindle step is 
 relie\-ed and tile tabk' allowed to rest li,iihtly on this outer bearing. Thus 
 adjusted the macliine work's with all the steadiness of a heavy planer, and 
 all the precision of the most accurate lathe. 
 
 Boring Bars. — The boring bars are square in section, accurately fitted to 
 their bearings. One bar is brought exactly central with the spindle. This 
 form of bar is \'ery stiff and rigid, and at the same time con\-enient to handle. 
 The tool holders are steel forgings, arranged to hold the tools in any required 
 position, and may be removed for other tool holders if desired. The bars 
 ma\' be Set o\er at an\' angle, and are quickly handled by means of worm 
 and worm wheel. They may be fed in any direction independently of 
 each other. 
 
 Counterweight. — Many attempts have been made to secure a balancing device 
 for the bars that will compare in simplicity and efficiency with our patented 
 device. This device, simple as it appears, is worthy of consideration. It 
 will be noticed by inspecting the cut, that a single chain is attached at one 
 end to an arm rigidly secured to the rail, and that a similar arm on the other 
 end of the rail carries a pulley over which the weiglited end of the chain 
 falls. There is a sheive on the face of each tool bar, and each saddle carries 
 two shelves straddling its bar, and the chain is looped over the single sheive 
 and under the tool bar sheive. This is a very. simple and perfect arrange- 
 ment, and possesses quite a number of advantages not apparent at first sight. 
 
 1. The counterweight requires to be only half as heavy as the parts to 
 be counterbalanced. 
 
 2. The counterbalance is perfect, no matter how much one or b(jth of 
 the tool bars may be set over for angular work'. As the saddles are moved 
 along the rail no effect is had upon the counterbalance weight, the sheive 
 simply moving along the chain. When the swing is unbolted so that it may 
 set over to an angle, the counterweight has no tendency to pull the swing 
 around and endanger a workman's life. 
 
 3. When a saddle nut is opened and a swing is quickly moved along 
 by the ratchet le\ei', the counterweight has no tendency to resist the motion 
 or to suddenly pull the swing along the rail out of control rjf the work'man. 
 
 4. There are no overhead arrangements to interfere with, or to be 
 interfered with by belts or cranes.

 Feeds. — Tln' feuds arc operated by ;i friction dislc, and hAw a ran,uo from ,,',- to 
 
 -j'';-incli. Tliis food is thoronglil)' reliable and very sim'ple in construction and 
 
 operation. It may be instantly varied to any de;^ree within its range. 
 
 At the end of the rail are a pair of gears by means of which the speed 
 
 can be increased or decreased lOO per cent, without shifting the friction disk. 
 The feeds are independent. The saddles or bars may be fed in the 
 
 same or in opposite directions at the same time. 
 Cross Rail. — The rail is of box-girder form, with wide bearings, it is raised 
 
 and lowered by power. The saddles are made right and left S() that they 
 
 ma)' be brought close together. The right-hand saddle has eiuick hand traverse 
 
 by rack' and pinion. 
 In General. — These Mills are the result of years of experience, both in their 
 
 construction and operation, and embody the most advanced practice in machine 
 
 todl construction. 
 
 Ample weight has been given to all the parts. All sliding fits are made 
 
 by scraping, and tiie workmanship throughout is of the best character.

 Boring; and Turning; Mills with Extensible HousinQ;s. 
 
 ' I 'HESE Mills are designed to meet the wants rif machine shops for a tool which 
 
 can be arranged to w(jrk to ad\-antage, occasionalK', upon pieces of \-trr\- 
 large diameter and \'et be oi con\-enient size for handling e\tr\'-da\- jobs. Anv 
 of our Mills of 10-foot swing and o\'er can be constructed in this way. 
 
 Tiie\' are made with extensions at the bacl<, and power apparatus for mo\-ing 
 the housings, together with the cross rail and attachments, back so as to take in 
 pieces of large diameter. The extensions are heav\' castings of ample strength, 
 fitted to the bed so as to form a C(.intinuous and true bearing with the bed frir 
 the housings, which are carefully scraped to fit. The truth and parallelism of the 
 housings and cross rail are therefore maintained in all positions. 
 
 Care is taken that in turning the largest work the boring bars are never 
 thrown out be\-ond the support of the housings. The strain is alwa\'s brought 
 directly against them. 
 
 The power of the machine is increased to enable the Mill to operate on work 
 of large diameter to excellent ad\'antage, and e\'ery facilit)' is pro\aded for con\'en- 
 ience in operation. An extension boring head, with bar having power feed, is 
 provided for boring work when the Mill is extended. 
 
 The change from standard to large work is quickl)' made by means of 
 power attachments.

 Tire Boring and Turning Mill, 5'-Foot Swing. 
 
 HEAVY PATTERN. 
 
 THIS Mill is designed for heavy duty, such as boring steel tire for car wheels. 
 it is of e.xtraordinary strength and power. 
 
 It is provided with a heavy Universal Chuck for holding tires or wheels. 
 This chuck is secured to the table of the Mill and may be removed, leaving the 
 table clear for ordinary work, if desired, however, the table of the Mill may be 
 fitted with chuck jaws and become the chuck itself. 
 
 The driving cone has five steps for a 4-inch belt, and is strongly back' geared, 
 giving ten changes of speed. Boring bars have 24 inches traverse. 
 
 Greatest distance from table to rail, 42 inches. Diameter of table, 55 inches. 
 
 Tire Boring and Turning Mill, 6-Foot Swing. 
 
 EXTRA HEAVY PATTERN. 
 
 THIS machine is designed for more than ordinary service. It was brought out 
 for turning the hardest steel tires, and is capable of taking two 34-inch cuts 
 with '-8-inch feed. The pressure on the cuts to do this work is 14,000 pounds. 
 
 The cross rail is 23 inches wide, cored out in box-girder form, and fitted with 
 saddles and bars of extra size and strength. 
 
 The boring bars are 10 inches square, fitted on four sides, giving them extra 
 large bearings. The bars are fed by screw and nut, and the power feed is 
 calculated for a resistance of 7000 pounds against it. 
 
 The driving cone has six steps for 4-inch belt, and is strongly back geared, 
 gi\'ing twelve changes of speed. Cone is geared to table in the ratio of 136 to i. 
 
 All feed gears are made of steel, and all gearing throughout cut from 
 the solid. 
 
 A circular water trough surrounds the bed to take away lubricating water 
 from the table. No slots are put through the table, thus preventing the corroding 
 action of soda or other lubricant upon the driving gear. 
 
 hi other respects the construction of the Mill is similar to our standard Mills 
 heretofore described. This machine is extraordinarily heavy for a tool of this 
 size. Weight, 42,000 pounds.

 Special Attachments. 
 
 WHEN required, we furnish tliese Mills witii special attachments for certain 
 work. These attachments are extras, not ordinarily furnished with 
 the Mills. 
 
 The prices named for Boring and Turning Mills do not include any of the 
 attachments, but when they are required prices will be named to cover same. 
 
 CYLINDER BORING BAR. 
 
 An upright bar with suitable boring heads is frequently provided for boring 
 large cylinders. The bar is stationary, the cylinder revolving about it on the 
 table of the Mill. The boring heads have automatic screw feed. 
 
 SLOTTING AND KEY-SEATING ATTACHMENT. 
 
 A crank disk, operated by tangent gearing and driven by independent 
 countershaft, is mounted on the top brace, made extra hea\y for this purpose. 
 An arm attaches to the bar of the Mill, giving an effective stroke of 16 inches. 
 
 This attachment will be found of service in key-seating large pulleys and 
 similar work, and will do the work speedily and well. 
 
 PULLEY TURNING ATTACHMENTS. 
 
 The Pulley Turning Attachments consist of an equalizing double driving 
 plate attached to the table, a tail stock attached to the cross rail, and a female 
 center for the face plate. 
 
 After boring the pulley it is put on a mandrel, and the mandrel placed 
 between the centers described above. The arms of the fqualizing driver then 
 come in contact with opposite pulley arms. 
 
 The pulley being turned on a mandrel without clamping, is turned true. A 
 large amount of work may be turned out in this manner. 
 
 THREAD CUTTING ATTACHMENT. 
 
 For cutting threads in large valves, chasing grooves in hoisting drums, etc. 
 An efficient device is made for this purpose. Heavy pitches may be cut, and the 
 work is done very rapidly. The Boring Bars of our Mills are especially well 
 adapted for such uses, being stiff and free from spring when cutting heavy pitches 
 with the bar extended and without lower support. A full description of this 
 device will be sent on application.

 Gentlemen : — Referring to your inquiry regarding the Boring and Turning Mills of your 
 manufacture, w hich we ha\-e had in use in our shops for nearly four years, it gives us pleasure to 
 state that THESE BORING MILLS HAVE GIVEN US SO MUCH SATISFACTION THAT WE HAVE 
 FROM TLWE TO TIME PLACED NEW ORDERS WITH YOU, UNTIL WE HAVE NOW FOUR OF 
 THEM IN USE. 
 
 These mills have been running twenty-two and one-half hours a day, without stopping, 
 since they were first placed in our shops, as we run two crews, one night and one day. We are 
 thoroughly satisfied that no better mills are made. Very truly yours.

 Gentlemen : — In answer to your request that we express to you our opinion of the various 
 kinds, and nf the numerous Niles Machine Tools we have ordered of you, we wish to say, that 
 the fact of our having FORTY-FIVE MACHINES now running in our extensive works, which we 
 purchased from you, besides those which you ha\'e on order, should be expression enough to the 
 normal mind that we are decidedly well pleased with our purchases, and we doubt if anvthing 
 we could write would demonstrate our appreciation more emphaticallv than that fact. 
 
 Our foremen and best mechanics, more intelligent and capable than which there are none, 
 although for the greater part unacquainted with the Niles Tools when they were employed by us, 
 are loud in their praises after over a year's experience with them. 
 
 THE lo-FOOT Planer and 14-FOOT Boring and Turning Mill are elegant tools; 
 
 massi\'e and rigid, at the same time accurate, scientifically designed and symmetrically propor- 
 tioned, capable of \-ery hea\-y work and much of it. THEY ARE ADMIRED BY ALL GOOD 
 judges, AMONG WHOM ARE TWO OF THE COUNTRY'S BEST TOOL BUILDERS, WHOSE 
 REPRESENTATIVES HAVE MADE MEASURE.WENTS AND SKETCHES OF THEM. 
 
 The i8-inch and lo-inch Slotters, the 54-inch, 36-inch, and 3o-inch Lathes, the large Radial 
 Drill, Horizontal Boring and Drilling Machine, 6-foot Vertical Mill, 18-inch Traverse Shaper, 
 30-inch Planer, and numerous other tools are also all you claim for them. Good workmanship 
 can only be accomplished with the best of tools and the most e.xpert mechanics. We wish to add 
 that we have struck that combination. Yours very truly,

 Gentlemen ; — We have in use one of your 14-Foot Boring Mills with e.xtensions to take in 
 20 feet in diameter, which has been in use in these works for the past five (5) years. 
 
 We can not SAY TOO MUCH FOR THIS TOOL. Since the writer took charge of these 
 works we have run it constantly day and night for the last seven or eight months, and have done 
 work on the same which probably has never been done on this style tool before, FINISHING 
 WORK OF MUCH LARGER DIAMETER THAN THE MILL WAS DESIGNED TO SWING, such as 
 turning up twenty-six (26) feet diameter, fifty-four (54) inch face groove wheels for two (2) inch 
 rope, and we have just finished a band wheel twenty-four (24) feet diameter by si.xty-two (62) 
 inch face, weighing thirty-six (36) tons. 
 
 The TOOL IS VERY POWERFUL, has an ample range of speeds for the various sizes up 
 to those named above, and is stiff and rigid under this heavy duty.

 30-Inch Vertical Turret Boring Machine. 
 
 T 
 
 HIS machine is i:rcatly suptriijr tC) any lathe for chucking:, facing, reaming, 
 ounterboring, etc., on small \\-ork. The work is set much more easily, 
 especially when it is of such shape that Unixersal chucks will not grip it. 
 
 It will take work 30 inches diameter, 14 inches face, and bore hubs 14 
 inches deep. 
 
 The table is 30^2 inches diameter. 
 
 The turret head is fitted \\ith four taper holes, arranged equally around the 
 circumference of head for four drill or boring bar shanks. 
 
 The turret slide moves in a long bearing, and has a travel of 24 inches, 
 allowing head to come down close to table for low work. 
 
 The table is dri\'en by be\-el gearing cut from the solid, by means of a 
 five-step cone for 4-inch belt, with ample range for all diameters of holes. 
 
 Three changes of feed are provided, the finest feed being proper for drilling 
 cast iron, with medium heavy drills. The two coarser feeds are for boring. 
 
 The feed is connected or disconnected by a clutch. When so disconnected 
 the feed shaft can be rotated b\' a ratchet le\'er shown in cut. This arrangement 
 allows the friction plate to be locked, and then gives a \'ery rigid feed for facing 
 rough hubs, etc., with a wide facing cutter. 
 
 The turret slide is moved by rack and pinion, and is fitted with a quick return 
 by hand. 
 
 Countershaft pulleys 20 inches diameter, 4^2 inches face, for 4-inch belt. 
 Countershaft speed, 80 revolutions per minute.

 Chord Boring Machine. 
 
 FOR BORING BRlLXiE CHORDS AND ■■ T BEAMS. 
 
 n~'HlS machine is far liea\-it-r and stron^it-r than is usually furnished for double 
 
 chord boring. 
 
 hi this class of work" it is essential that the two spindles shall be exactly 
 parallel in all positions, and failure to accomplish this has caused some feeling <")f 
 distrust against all double machines. We hax-c, however, built several of these 
 machines, earefull}' designed to meet this \'ery objection, and they are in all 
 instances giv'ing complete satisfactinn. It is essential that the bed shall be 
 careful!)' le\'eled on a solid foundation. If this is rightly done the two spindles 
 will work together with tiie utmost precision. 
 
 Arranged with two independent heads on one bed, adjustable on the bed for 
 varying lengths. The bed ma_\- be made of any length to suit. 
 
 The two heads are complete in themscK'es, dri\'en independently, and with 
 all attachments, feeds, etc., for a complete boring machine. The\' are of great 
 strength and power. The power is ample for boring four holes, punched 4 to 8 
 inches diameter, at one time, and the range of speed is such as to adapt the 
 machine for drilling down to i^-inch holes. 
 
 The two columns have both power and hand movement for adjustment on 
 the bed. 
 
 The heads have 18 inches reach, boring to the center of 36 inches. They 
 will take in under the cutter work 36 inches high. 
 
 Spindle has 24 inches traverse. 
 
 Range of work in length, 5 to 50 feet between centers. 
 
 Feeds are by power, and are reversible up or down, and range from Jjj to 
 -g-'j-inch for heavy work, and coarser feeds for light work. 
 
 The bed is formed of wrought iron "1" beams, 15 inches deep. 
 
 Two independent carriages for supporting work on the bed are provided. 
 
 The countershaft has three pulleys 26 inches diameter. Outside pulleys 11 
 inches face, center pulley 6}A inches face. Speed, 200 revolutions. Use 6-inch 
 belt for driving spindles, 4-inch crossed belt for traversing columns on bed.

 Cylinder Boring Machines. 
 
 THESE machines are built in several st)'les to suit the varying practice of loco- 
 motive and stationary engine shops. The distinguishing feature in each 
 style, aside from nominal capacit}-, is the manner in which the boring bar is 
 operated. In one style the bar is simply held between centers. It has a sliding 
 head operated by means of a feed screw and gears at one end. Another style, 
 illustrated on opposite page, has the bar attached to the tail stock and arranged 
 to be withdra\\-n. In this form, also, the bar is provided with a sliding head and 
 feed scre\\'. In the third style the head is clamped to the bar and moves with it. 
 In all styles the bar is dri\'en bv tangent gearing. 
 
 No. I Cylinder Boring Machine. 
 
 FOR BORING LOCO>iOTI\"E CYLINDERS. 
 
 WILL bore cylinders from 16 to 22 inches diameter. 
 The boring bar is 8 inches diameter. Power is transmitted through tangent 
 gearing, affording a \'ery smooth, e\'en motion to the boring bar, particularly 
 desirable in c\iinder boring and work of a similar character. Cylinders bored in 
 this manner have a \'ery smooth finish. The cone has three speeds for a belt 
 4 inches wide. The boring head is traversed on the bar by means of a screw. 
 
 There are five changes of feed, ranging from ^ to f of an inch. 
 
 Two boring heads are furnished with the machine, for large and small 
 cylinders. Heads are also furnished for facing and turning the flanges of cylinders. 
 
 The time required for boring c\dinders is reduced to a minimum by the use 
 of this special machine. The countershaft has two pulleys 28 inches diameter, 
 4^ inches face. Speed of countershaft, 125 revolutions per minute. 
 
 No. 2 Cylinder Boring Machine. 
 
 FOR BORING AND FACING L0C0.\10T1\'E CYLINDERS. 
 
 THE cut on the opposite page represents this machine as arranged for cylinders 
 28 inches diameter and 39 inches long, including sinking head. In this 
 machine the boring bar is withdrawn from the work by a rack and pinion move- 
 ment attached to the tail stock. The boring head is tra\'ersed on the bar by a 
 screw. Facing heads are provided, attached to sleeves on the head and tail stocks. 
 
 The boring bar is 9 inches diameter. Power is transmitted through tangent 
 gearing, which insures a steady motion to the bar and freedom from chatter. 
 
 The feed is obtained by change gearing, and is connected and disconnected 
 by a clutch engaging with the feed screw in the boring bar. This clutch is oper- 
 ated by a lever at the end of the bar, within easy reach of the operator. Two 
 boring heads are furnished with the machine, for large and small cylinders. 
 
 Countershaft has two pulleys 28 inches diameter, 4^ inches face, and should 
 run 125 revolutions per minute.

 FOR BORlNtj AND FACING STATIONARY ENGINE CYLINDERS. 
 
 T 
 
 HIS machine is similar in dcsiiin to tlie No. 2, lierctotdre described. It is 
 
 intended for Ir^oring and facing stationary engine cylinders up to 36 inches 
 diameter and 60 inches long, boring and facing both ends at the same time. 
 
 The boring bar is operated b\' rack' and pinion movement on the tail stock. 
 It has fnur feeds operating in both directions. Tile head is arranged to be set by 
 hand adjustment, showai abo\e the bar in the preceding illustration. 
 
 The dri\'ing cone has four steps fur a 5-inch belt, and dri\es the bar by 
 means (if tangent gearing, insuring smooth and steady action. 
 
 Facing heads are clamped to slee\'es re\'i)l\-ing with the bar, and when not in 
 use may be undamped and remain stationarx'. 
 
 The tail stuck' is adjustable on the bed, to suit c\'linders of ditterent lengths. 
 
 Two saddles are pro\'ided, which extend across the bed and are clamped to 
 it. These are for holding the work. 
 
 The facing head on the head stock is driven by the slee\e which dri\'es the 
 boring bar, so that if desired the tail stock and bar can be removed and engine 
 frames can be placed on the saddles and be faced up to receive their c\dinders. 
 By using a special bar in the sleex'e the stuffing bo.xes could also be bored. 
 
 Note.— Both the No. 3 and No. 2 Cylinder Boring Machines pre\-iously described, can 
 be arranged with the cutter head clamped on the bar, in whicli case the bar is fed by rack and 
 pinion back of the head stock. This arrangement is quickest in manipulation, but occupies a 
 great deal more room and is far more expensi\'e. 
 
 No. 4 Cylinder Boring Machine. 
 
 FOR BORING AND FACING STATIONARY ENGINE C^XINDERS. 
 
 THIS machine wall bore c\dinders up to 60 inches diameter, and any length that 
 ma\- be desired. It consists rif large head and tail stock's mounted upon a 
 heav\' bed, wliich is set le\'el with the floor. 
 
 The bering bar is held between centers, as in ordinary lathe practice, wdrile 
 the bnring liead is fed afjng the bar b}- means of a feed screw and gears at 
 one end. 
 
 The spindle is \'er\' large and is dri\-en by means of tangent Liearing, in the 
 same manner as all the foregoing Cylinder Boring Machines. 
 
 Tills machine is provided with a large face plate, with a facing head operated 
 b\' star wheel feed. It can be quickh' remox'ed, and work can then he fastened 
 upon the face plate and be operated upon as in ordinary lathe practice. 
 
 This machine is \'ery powerful, yet extremely simple in its construction. 
 One firm of engine builders wdio are using one of them say it has reduced the 
 cost of cylinder borintr and facing to less than one-half of former cost.

 No. 5 Cylinder Boring Machine. 
 
 FOR BORING OXINDERS, FACING ENDS. AND BORING VALVE PORTS OF CORLISS 
 
 ENGINE CYLINDERS. 
 
 'T^'HIS machine is similar in dcsi^L'n to tlie No. 3 maclTinc before described, i.e., 
 
 the arrangement of the boring bar and facing heads is the same, and all the 
 manipulations are under the same easy control of the operator. The distinguishing 
 feature, howe\-er, is that in addition to the boring bar and facing heads, a pair of 
 auxiliary columns are located on extensions in front and back of the bed, and 
 adjustable thereon to any required position. One of these columns has a saddle 
 arranged to slide vertically upon it, carrying a boring spindle to which power is 
 communicated from an independent countershaft. Upon the other column a knee 
 is mounted, carrying an outboard hearing for the bar. 
 
 Automatic feed and quick hand adjustments are provided. 
 
 With this arrangement advantage is taken of the setting of the Corliss 
 cylinder for boring, to bore the valve ports at the same time. This saves one 
 handling, insures the valve ports being square with the cylinder, and saves the 
 time which would otherwise be consumed in boring the ports, as there is always 
 ample time to do this while the other operations of boring and facing are going on. 
 
 This machine is capable of boring cylinders up to 42 inches diameter and 
 10 feet long. 
 
 Two bars are furnished, one 7 inches diameter for cylinders up to 18 inches, 
 the other 12 inches diameter for cylinders above that size. 
 
 The machine is driven b\' powerful tangent gearing, in the same manner as 
 all the foregoing Cylinder Boring Machines.

 Horizontal Boring and Drilling Machines. 
 
 A MONO tht many labur-saviiiL; tools now cominf^ into central use in our best 
 sliops, none occupy a more prominent position, or are held in higher esteem, 
 than the Hcjrizonta! Boring and Drilling Machine. 
 
 As a general utilit}' machine it tills a space which can be occupied by no 
 other tool, it \\'ill bore ; it will drill ; it will face, ream or mill. 
 
 With its closely lltted, accurately adjusted slides it will bore or drill holes 
 with all the accurac}' of an expensive jig, and this, too, whetlier the axis of the 
 holes lie in parallel or angular planes. 
 
 It supplements the heavy milling machine, in that the latter class of machines 
 are arranged more particularly to work at right angles to the axis of the spindle, 
 wdrile this machine has much greater range in line with the spindle, and also in 
 vertical distance from it. 
 
 It is a much better machine for accurate boring than either the lathe or drill 
 press, since the table and cross slides are readiK' adjustable to the fixed position 
 of bar or drill, without the use of blocking. 
 
 As a machine for settmg feathers in shafts, or milling slots in work, it fulfills 
 the functions of planer, slotter or cotter drill. 
 
 Where parallel holes are to be bored in a number of pieces, the use of stops 
 on the slides will sa\'e the expensive laying out by the fitter. 
 
 We mak'e these machines in four sizes. They are all of the same general 
 design as shown in the cut, and consist essentially of a heavy column mounted 
 on a rigid base and carr}'ing the boring spindle and feed gear. 
 
 An adjustable table is gibbed securely to the face of the column. It is 
 supported upon, and also raised and lowered by, two screws of large diameter, 
 connected by a iKjrizuntal shaft and bevel gearing. 
 
 The table carries a saddle and cross table with compriund mQ\'ement. The 
 spindle has rapid hand movement bv rack and pinion. 
 
 The revolving sleeve surrounding the spindle has a face plate to which a 
 head for facing may be attached. 
 
 The outer end of the boring bar is supported bv an adjustable yoke, which 
 also affords additional support for the table, and can be removed when desired.

 Horizontal Boring, Drilling and Milling Machine. 
 
 nPHlS machine, as its name implies, is designed for ail classes of boring and 
 
 drilling, and in addition has ample power and the necessary feeds for milling. 
 For the latter service the machine is especially valuable, doing work that otherwise 
 would require a large planer. 
 
 The spindle covers a very large surface, reaching any point in a surface 9 
 feet or more in length by 6 feet in height. Consequently it will finish very large 
 work, and the piece requires but little handling. In most cases all surfaces may 
 be milled off and holes drilled or bored in a piece with one setting. Economy of 
 operation on very large work has to do almost entirely with the saving in expense 
 of handling. Frequently the operation to be performed by the machine is a short 
 one, and the time handling the piece to get it into position requires by far the 
 greater expenditure of time and consequent expense. 
 
 To plane a piece, say 9x6 feet, would require a very large planing machine, 
 which means a heavy investment. This is reduced materially by the machine 
 illustrated. In a planer the work is carried forward and back, requiring large 
 power to move the piece alone, and a loss of time in reversing. With this milling 
 tool the piece remains stationary, the tool moving up to its work, and the cut 
 is continuous. 
 
 The advantages of such a machine for milling are more novel, but no greater 
 than for the operations of drilling and boring. The same advantages in reaching 
 the work, without extra handling of the piece being operated on, are obtained. 
 In addition are the recognized advantages of boring and drilling with a horizontal 
 spindle. The work resulting is most accurate. Holes are drilled in line, when 
 necessary, and easy adjustment of the spindle is attained. 
 
 In this machine the spindle is extra large, has a wide range of speeds and 
 feeds, and may be run in either direction, either right or left-hand. 
 
 Various styles of tables, or floor plates, for securing work can be used. One 
 of these, a square table, is shown in the cut. 
 
 These are placed in front of the machine and may consist of plain floor plates 
 of cast iron planed true and T slotted. Or a compound table may be used with 
 traverse by screw in both directions. Or, in addition to the compound table, a 
 circular motion may be added.

 We fiiniish tables, or the user ma\' prcnide such as may he best suited to 
 his \voi"l<. 
 
 Some of the ad\'anta;aes of this tool max- be learned from the following 
 statement of work done at the shops of Gordon, Strobel & Laureau, Philadelphia. 
 The following is an extract from a letter from them. 
 
 "The tool which especialU- meets nur approval is the Horizontal Milling and 
 Boring Machine. The spindk- carrying the drill or drilling head may be projected 
 a distance of 48 inches fmm the face of the machine. It has a horizontal 
 movement of 108 inches and a vertical one of 72 inches. These limits cover a 
 wide range of work. For instance, in machining the bed plate of a blowing 
 engine, we support the casting vertically in front of the machine, face the bearings 
 for housings and for the steam cylinder, mill the seats for the pillow block caps, 
 treating the various heights, or le\'els, and directions without change in the position 
 of the bed plate. The latter is then lowered to a horizontal position and we 
 proceed to bore out the main bearings. Likewise the blowing engine housings, 
 after being bolted firmly together and to stools, are machined and drilled to gauge 
 in a remarkably short time. In all the foregoing, parallelism of surface is insured. 
 We bore out each air valve seat in our blowing cylinder heads, reaching each and 
 every one v/ithout change, the head being 9 feet 6 inches in diameter. 
 
 " Our patented tuyere stocks require spherical joints, which must be machined 
 accurately. These joints we get with one cut, accomplishing the same quickly 
 by means of a simple cutter head attachment to the milling tool spindle. 
 
 " Enough has been said to e.xemplify the wide range of the tool. It is the 
 first eminently good step out of the old range of lathe, planer, etc., etc., that is 
 applicable to general work."

 General Description. 
 
 'T'HE; machine consists of a heavy column, 10 feet 6 inches high, mounted on a 
 
 bed plate of any length to suit requirements. The column is moved along 
 the bed plate by power, operating through worm gear and rack. The column is 
 31 inches wide on the face and is fitted with a heavy saddle 40 inches square, 
 carrying the spindle. 
 
 The saddle has a vertical traverse on the column of 6 feet, and is raised and 
 lowered by heavy screw. It is balanced by counterweight hung in the column. 
 
 Boring and milling spindle is hammered steel, ^}4 inches in diameter. It 
 slides in a heavy, revolving sleeve, and has a traverse of 4 feet. It revolves in 
 either direction, right or left-hand, reversing by lever conveniently located, and 
 has eight power feeds ranging from -^-Vinch to ^-inch per revolution of spindle. 
 h is also provided with hand feed and quici< return. 
 
 The milling feeds are six in number, ranging from yV-inch to y'^-inch per 
 revolution of spincile. These feeds are applied only to the column and saddle, 
 and are by power only. 
 
 Any of these feeds for the quick motion may be utilized to set a drill, boring 
 bar or milling cutter to work anywhere on the surface which the machine 
 will reach. 
 
 At one end of the bed plate is placed the driving gear, milling feed and quick 
 traversing mechanism for the column. The quick power traverse of the column 
 has a speed of 5 feet per minute. 
 
 The driving cone has six steps for a 4-inch belt, and is strongly back geared, 
 giving twelve changes of speed ranging from 2 to 200 revolutions per minute, and 
 has ample power for boring up to 24 inches diameter. 
 
 A platen is placed in front of the column, convenient to the spindle, for the 
 operator to stand on, and all movements of the spindle, saddle and column may 
 be started, stopped or reversed by levers conveniently arranged on, and traveling 
 with the saddle, within easy reach of the operator while he watches the work. 
 
 Countershaft and wrenches are furnished.

 MILLING CROSS HEAD GUIDES IN A LARGE ENGINE "A" FRAME. 
 
 TN order to show some of the advantages which this machine possesses for 
 operating quickly on large, unwieldy worl<, we present herewith a few examples 
 which, it will at once be seen, would require considerable handling and expense 
 to finish in any other manner. 
 
 The first example we present is that of an "A" frame for a vertical engine, 
 such as are used, for instance, in many ice machines. 
 
 The machine is here shown milling the cross head guides. To do this on a 
 planer would require a very large machine, which takes up a large amount of floor 
 space and involves a considerable outlay, while in this way the frame is simply 
 picked up by a traveling crane and placed in proper position in front of this 
 machine, close up to the column. A milling head is then keyed to the spindle and 
 the saddle set to feed vertically on the column. In this manner both guides may 
 be milled. 
 
 A facing head is then put on in place of the mill, and the guides faced up on 
 both sides. After this is done the main and rocker arm bearings, etc., may be 
 bored and faced. All this, together with the drilling and tapping for brackets, 
 etc., may be done at one setting, as the machine is provided with all the necessary 
 movements to bore or face in any required position, or to mill in either horizontal 
 or vertical planes.

 FINISHING HOUSING FOR LARGE BENDING ROLLS. 
 
 n^HE illustration on the opposite page shows this macliine horing the main roll 
 
 bearing in a large housing for bending rolls. 
 
 In this case the housing was placed upright on the table and secured firmly, 
 close to the column of the machine. 
 
 We rely generally upon securing the work firmly to the table or floor plate 
 without the use of braces, if possible, as they are most apt to cause springing, 
 which will result in the work being out of true. In this case the housing was 
 clamped by its feet only, and was stiff enough to withstand very good cuts. 
 The cutter head shown was then secured to the spindle and the main bearing 
 finished. All the remaining holes, bosses and surfaces were then bored, faced, 
 drilled or tapped in succession at the same setting. 
 
 It will at once be apparent what a great sa\'ing in time is effected in this 
 manner over those processes requiring successive setting of such heavy pieces.

 FINISHING A LARGE SLOTTER COLUMN ON REVOLVING TABLE. 
 
 ' I 'HE accompanying illustration presents another example of work with this 
 
 machine, drawn from our own practice. 
 
 This example illustrates a large class of heavy work upon which it is 
 necessary to operate on several angular planes. For work of this class the table 
 should he a compound one with circular movement. We furnish these with 
 power movements in all directions. 
 
 The rough or planed casting is securely bolted to the table in such manner as 
 to present most of the surfaces which are required to be operated upon, by simple 
 revolution of the compound table. This table is graduated, and thus it will be 
 seen that the various holes and surfaces can be set with the greatest accuracy. 
 
 The successive surfaces are then treated as presented in the manner 
 previously shown, according to requirements. 
 
 In the example shown, which is one of our slotter columns, if it had been 
 required to face the base of the column to fit it to the bed (as is done on the 
 large sizes), a milling cutter could be passed entirely around the base at one cut, 
 and then the necessary bolt holes drilled, all at one operation. 
 
 It is hoped that these examples will serve to show how easily, quickly and 
 accurately large castings can be treated by this machine.

 to say that the Horizontal Boring, DriHing and Milling Machine which we hought from you o\'er 
 a year ago, is one of the finest tools we ha\e e\er seen and has done lis splendid service. 
 
 A large amount of the heavy work of a complicated character that we have done on this

 you. Tlie usefulness of such a tool to any engineering workshop doing heavy work is nearly 
 Indispensable, as its name indicates. We now feel that it would be impossible for us to get 
 along without it. 
 
 We hope that the Horizontal Boring Machine which you are now about shipping to us, and 
 wliich is of another class, will give us as good satisfaction as the (ine we now Iiax-e, and we shall

 Niles Tool Works, Hamilton. O. PHILADELPHIA, Feb. 22, 1889. 
 
 Gentlemen : — Replying to your inquiry of the 7th inst., asking how we are pleased with 
 the large lot of tools we recently purchased from you and placed in our works, we would say, 
 generally speaking, we are very well pleased. The tools throughout are up to your usual standard 
 and are efficient and accurate. 
 
 We are highly pleased with the large and small Boring and Turning Mills. The larger 
 tool, with a Cylinder Boring Attachment, is well known to the mechanical public, butwe fancy, 
 from seldom seeing these tools as small as 60-inch swing, such as you sent us, that the advant- 
 ages of such a tool are not properly appreciated. The rapidity with which all work can be 
 chucked, centered, bored and turned up to 60 inches on this machine far surpasses similar oper- 
 ations in connection with lathe work, owing, mainly, to the adjustment of the two tools to a 
 common center. Being in a horizontal direction, no counterweights are required. 
 
 The tool which specially meets our approval is the HORIZONTAL BORING, DRILLING AND 
 Milling Machine. The spindle carrying the drill, or drilling head, may be projected a distance 
 of 48 inches from the face of the machine. It has a horizontal movement of 108 inches, and a 
 vertical of 72 inches. These limits cover a wide range of work. For instance, in machining the 
 bed plate of a blowing engine, we support the casting vertically in front of the machine, face the 
 bearings for the housings and for the steam cylinder, mill the seats for the pillow blocks and pillow 
 block caps, treating the \'arious heights, or levels, and directions without change in the position 
 of the bed plate. The latter is then lowered to a horizontal position and we proceed to bore out the 
 main bearings. Likewise the blowing engine housings, after being bolted firmU- together and to 
 stools, are machined and drilled to gauge in a remarkably short time. In all the foregoing, 
 parallelism of surface is insured. We bore out each air-\-al\-e seat in our blowing cylinder heads, 
 reaching each and every one without change, the head being 9 feet 6 inches in diameter. Our 
 patent tuyere stocks require spherical joints, which must be machined accurately. These joints 
 we get with one cut, accomplishing the same quickly by means of a simple cutter-head attachment 
 to the milling tool spindle. 
 
 Enough has been said to exemplify the wide range of the tool. It is the first eminently 
 good step out of the old range of lathe, planer, etc., etc., that is applicable to general work.

 Gentlemen :— We have had one of your Horizontal Boring and Drilling Machines, with 
 four feeds and compound rest with swivel, in use for something over a year — much of the time 
 night and day — and have found it a very substantial and satisfactory tool. One drawback to 
 this class of tools in many shops is entirely removed by the application of the compound rest, 
 which enables us to do a great variety of work commonly done on lathes, and thus keep the 
 tool busy. The new io-16-foot Boring Mill arrived yesterday. 
 
 Very truly yours, 
 
 West Superior iron and Steel Co.,

 Universal Radial Drill. 
 
NILES TOOL WORKS, HAAMLTON, OHIO. 
 
 Universal Radial Drilling Machines. 
 
 NEW AND IMPROVED PATTERNS. 
 
 T^HE cut on the opposite page represents one of our latest impro\'ed Radial 
 
 Drills. They are built from new patterns and are designed to meet the 
 requirements of modern shop practice. The bearing of the arm on the column 
 is made \'ery long, and the arm itself is made of a very rigid form. 
 
 This type of Radial Drill has been manufactured by this company for the 
 past twenty years, and has been found to be extremely serviceable for all 
 classes of work. From time to time improvements have been made, always 
 keeping this machine up to the demands of the times. 
 
 In this machine it is much easier to move the drill to the work' than the 
 work to the drill. One man can accomplish it quickly and without any effort. 
 Under ordinary circumstances it is e.xtremely troublesome to meet the conditions 
 of getting the work level, and at the same time have the center of the hole 
 to be drilled directly under the point of a rigidly fixed drill. More time is 
 generally wasted in getting the work in position, and readjusting and leveling 
 it, than is required for drilling the holes. 
 
 The operation of this machine can be explained as follows: Place any 
 heavy piece of work within the circle of 9 feet diameter; put it on the floor, 
 on the base, or on the table, as may be most desirable; level it without regard 
 to the drill ; lower the drill to it, raise the drill to it, swing the drill to it, use 
 at an angle if necessary, and the work need not be disturbed till the drilling 
 is done. 
 
 This machine serves the purpose of more than one drill press. It has 
 such a range that one piece of work can be temporarily abandoned and 
 another piece undertaken, which recommends its use in smaller shops. 
 
i84 NILES TOOL \\'ORKS, HA;^\lLTON,OHIO. 
 
 General Description. 
 
 PX HEAVY, rotatin,^ column is mounted upon a lim^ supporting slee\-e, wiiicli 
 
 is rigidh' secured to a lieavv base plate, and is accurate!)' fitted to a 
 bearing in tlie column. 
 
 The ciilumn is turned all o\'er, and upon it the radial arm is mounted. 
 This has also a \'er\' long, accurateK' fitted bearing, and can be clamped in 
 an\- position. The crdumn can also be clamped rigidly to the base plate, thus 
 making tlie whole machine verv stitf. 
 
 The machine is dri\'en from an overhead countershaft operated by bevel 
 gearing, and an upright shaft to drive the central spur gear seen at the top 
 of the column. This dri\'es the upper cone bv means of the external upright 
 shaft and bevel gears, and also communicates motion through tumbler gearing 
 to the screw, which is operated to raise and lower the arm by power. 
 
 The upright central dri\'ing shaft is splined through the gear, thus allowing 
 the countershaft to be located at any height from 9 to 16 feet abo\'e the floor. 
 
 Motion is communicated to the drill spindle from the cone, which is 
 strongly back geared, by means of spur gears, a splined shaft and bevel gearing. 
 
 The arm is of the best form possible to resist the strains to which it is 
 subjected. It is made in form similar to a box girder. It is made in one 
 piece, the slee\'e surrounding the column forming a part of the same, and a 
 heavy web on the upper side resists the upward strain. 
 
 The drill head is securely gibbed upon the arm, and is adjusted to any 
 position on the arm b\' means of a hand wheel and rack and pinion. It is 
 also adjustable to an_\' angular position upon its saddle, to which it is securely 
 clamped. It is nicely balanced, so that clamp bolts may be loosened for 
 angular setting without danger of breaking drills or injury to the operator. 
 
 The column of the machine is set upon rollers bearing entirely upon their 
 periphery. This arrangement enables the operator to handle the machine 
 
MLES TOOL \\'Of^KS, HAAMLTON. OHIO.

 with the greatest ease. The combined movements of tlie arm and head enable 
 tile drill to be rapidl\- brought t(.) an\' desired position. 
 
 When the machines are required to drill a number of parallel holes on 
 the end of work, we recommend, \\here\'er practicable, that a pit be made on 
 one side of the base and lined with T- slotted plates for holding work. This 
 ob\-iates the need of extra high columns and keeps the arm within easy reach 
 of the operator, and in the best position to resist strains.

 ARM, 7 FEET LONG. COLUMN, g FEET HIGH. 
 ( Patented December t4, 1869.) 
 
 "T^HE column is 9 feet high, turned true and parallel. When the arm is 
 
 raised to the top of the column the distance between the base plate 
 and the end of the drill spindle is 6 feet 5 inches, admitting work nearly 
 that height under the drill. 
 
 The distance from the column to the drill spindle is 5 feet 9 inches, 
 consequently a hole can be drilled in the center of a circle 11 feet 6 
 inches in diameter, a reach beyond that of any ordinary drill press. The 
 spindle is made of steel, and is 2^1- inches diameter. It has the neces- 
 sary traverse for deep holes. Has quick return. 
 
 The driving cones have four steps, and are powerfully back geared, 
 giving eight changes of speed. These cones are quite accessible, and any 
 desired change of speed can readily be made. The driving power is very 
 great and fully equal to any requirement. All gearing is cut from the 
 solid. The power feed is very convenient. The base is a substantial cast 
 iron plate turned and T- slotted. It extends over one-fourth of the circle 
 made by the swing of the arm. The box table may be moved to any 
 position on the base. It is provided with a cupboard for tools. The outer 
 end of the radial arm is supported by a column, and is counterweighted. 
 
 Countershaft has two pulleys 16 inches diameter, 4 inches face, and 
 should run 120 revolutions. 
 
 This machine is designed for heavy work. Holes of large diameter 
 may be bored, and cylinder heads and flanges as large as 24 inches 
 diameter may be faced off. 
 
 A large steam pump works are using one of these machines for boring 
 out seats for pump vah'es, facing the flanges of the pump cylinders and 
 other heavy work- of a similar nature. 
 
 The arm is in the shape of a double web, the saddle sliding on the 
 top and the spindle operating between the sides. It has a very long 
 bearing on the column, and, being supported at the outer end, is very rigid. 
 
 The spindle has vertical traverse only. It can not be set over to 
 operate at an angle, as on the smaller sizes. 
 
 For a great variety of work this machine has no equal. A great saving 
 in cost may be effected by its use.

 Multiple Traverse Table Drill. 
 
 T^HIS machine is similar in design to our regular pattern of multiple 
 
 drill, except that it is provided with a table arranged to slide upon 
 the bed. 
 
 Machines of this class are especially desirable when it is required to 
 drill a number of holes in heavy pieces clamped together, such as vault 
 doors, etc. In work of this kind the separate pieces can be fastened 
 together upon the table and any desired part brought under the drills 
 quickly and accurately, without risk of disarranging any of the work done. 
 By using stops on the bed and rail, duplicates may be easily made, or 
 holes made to match nicely when it is impossible to drill them together. 
 
 It can be built with one or more spindles mounted on the rail. The 
 drills can be adjusted to ■jy'z inches between centers. The spindles have 
 12 inches travel, and each has independent power feed with three changes. 
 They are also arranged for hand feed, and each is counterweighted and 
 has quick return. 
 
 The machine is capable of drilling three ij<-inch holes or two 2-inch 
 holes at the same time through steel plate. 
 
 Clearance between housings, 48^ inches. The work is mounted on a 
 table 7 feet long, 36 inches wide. It is movable by rack and pinion on 
 a bed 10 feet long.

 Multiple Spindle Wheel Drill. 
 
 FOR DRILLING STEEL-TIRED CAR WHEELS. 
 ( Patented July 28, 1885,) 
 
 n^HE drill has twenty-seven spindles, divided into two i^roups. 
 
 The center group, consisting of nine drills, is contained in one head, 
 and is used for drilling the holes for huh bolts 
 
 The outer group, consisting of eighteen drills, is used for drilling tiie 
 holes for tire bolts, and is so arranged that all of the drill heads, or a 
 part of them, can be moved in or out radially, to suit different diameters. 
 
 The drill spindles run in brass bushes, adjustable for height, by which 
 means the height of any drill point can be regulated to suit. 
 
 The two groups of drills are separately driven by a set of gearing, 
 giving Velocity to the drills proportioned to the hardness of material encountered. 
 
 The work is placed on a comprjund table having a self-centering chuck 
 with circular motion for any desired adjustment of wheel under drills. 
 
 To facilitate handling the wheel, the chuck table moves on ways, 
 enabling the wheel to be brought out from under the drills and lifted by 
 an overhead crane or pulley block. 
 
 The feed is accomplished by two heavy steel screws under the work 
 table, moving the same up to the drills. The feed pulleys are tight and 
 loose, and feed belts are provided with convenient shifters, whereby the 
 feed can be instantly stopped. 
 
 The work table is nicely balanced by counterweight under the sole 
 plate, allowing rapid vertical adjustment of table by hand. 
 
 This machine may be furnished with a fewer or greater number of 
 spindles, as may be required, or a different arrangement of the spindles to 
 suit the number and arrangement of bolts in the wheel.

 TWO SPINDLES. 
 
 F=JOR drilling steel rails for the fish-plate bolts. 
 
 ^ This is a special machine, designed for this particular service in order to 
 accomplish it in the most efficient and economical manner. The machines are 
 generally used in pairs, one machine at each end of the rail. 
 
 The drills are adjustable horizontally, to drill from 31^ to 8 inches from center 
 to center of drills. Powerful down feed of both drills simultaneously, and a 
 quick return by hand movement. 
 
 The spindles and gearing are of steel. 
 
 The countershaft has two pulleys 20 inches diameter, 4}( inches face. 
 
 Speed of countershaft, no revolutions per minute. 
 
 Rail Drilling Machine. 
 
 THREE SPINDLES. 
 
 rOR drilling steel rails for the fish-plate bolts. 
 The capacity of this machine is three holes, 13^ inches diameter, in steel rails. 
 
 The range of drills is from 4 to g inches between centers. By means of 
 adjusting screws the drill head can be rapidly set to any required position. The 
 drills are set in heavy sockets, and held by two strong set screws. This enables 
 all of the drill points to be set on a level. 
 
 The feed on the three drills is simultaneous by acting on the saddle carrying 
 the three drill heads. Saddle is counterbalanced and has quick return. The 
 range of feed allows the use of drills from 10 inches in length under socket to 
 about 4 inches. Feed is transmitted to saddle by means of slip-gear on side of 
 machine opposite to driving pulley. Two changes of feed can be obtained by 
 simply transposing the slip-gears, thus giving a heavier feed when soft material 
 is worked, and a lighter feed for hard material. 
 
 The driving pulley is attached to saddle, and idlers are provided to maintain 
 the tension of belt in all its positions. The rail is supported on steel blocks and 
 clamped against the clamping block on its back. The end adjustment of rail is 
 obtained by a heavy set-screw in the cast steel bracket on the side of bed. The 
 cuttings drop through the opening in the bed to the floor in front, and can readily 
 be removed. 
 
 Our patterns are arranged so that the machine can be made either right or 
 left, as may be desired. All of the driving gear is made of steel to avoid breakage. 
 We consider this machine the heaviest and strongest of its class in the market. 
 
 Countershaft pulleys 24 inches diameter, 6 inches face. 
 
 Speed, 90 revolutions.

 Gentlemen : — Repyling to your favor of the 22nJ, the No. 2 Radial Drill purchased from 
 you in 1887 (the third one of your make we have placed in our works), is A i in every respect, 
 giving us perfect satisfaction. We ha\'e used it constantly since setting it up and ha\e had 
 occasion to drill holes in our heavy castings at every conceivable angle. The machine has 
 done its work perfectly and is in every ^\ ay reliable. Our «ork is particularly adapted to the 
 use of a radial drial, and tlie test we have given it is a severe one. We will be pleased to have 
 you refer any purchaser to us, or show any one the machine in operation.

 Gentlemen: — In reply to yours of February 7th, as regards the Radial Drilling Machine 
 we have of yours in use, we beg to say that we now have SEVEN of them in use in our works, 
 bought of you at various times since 1879. We also have several other makes of drills in use, 
 but we cheerfully say that we like your machines better than any others we have used or seen. 
 They are adapted to a wider range of work, are more easily changed from job to job, more con- 
 venient to operate, handle, etc.; hence more work can be done in a given time. The four 
 machines bought of you in 1887, which are of your new pattern, cannot be made better. They 
 look and work admirably. We shall advocate them wherever we can, as we know they are 
 good. They are a first-class boiler shop drill, also for general drilling, tube heads, etc., they can't 
 be beat. Yours truly,

 Niles Special Pulley Lathes. 
 
 ( Pattntei April 2j, 1173, and Fctruap.- 5. i£c4. 
 
 SPECIALLY designed for turning pulleys, gears ( buth spur, be\'eled, and mor- 
 tised), small tl\'-whcels, and work of a similar character. As will be seen 
 from the cut, these Lathes are \-cr_\- strongly built. The bed is made especially 
 wide, and the spindle placed \ery low in order to a\-oid the high tool posts other- 
 wise necessar}', and which are alwa\-s a source of anno\'ance where hea\-_\- duty 
 is required. 
 
 Power is transmitted to the spindle through tangent gearing, gi\'ing a stead\' 
 and powerful motion, particularh- desirable when turning off the face of gears, 
 and similar work. 
 
 The puile\'s, being first bored, are placed on a mandrel and are dri\'en bv an 
 equalizing driver of the Clement type, distributing the strain e\-enh' on the 
 arms. This method of dri\-ing is far preferable to an_\- method of clamping to a 
 face-plate by the arms without the use of a mandrel, as it is almost impossible to 
 produce true work by such methods. 
 
 The tool slides are mounted upon short, stiff cross rails, which are adjustable 
 on graduated surfaces of the bed to suit the diameter of pulle}- to be turned. The 
 rails ma\' be set over at an angle to gi\'e an\' desired degree of "crown." Tools 
 are thus operated on both sides of the machines. 
 
 Feeds are operated from the end of the dri\-ing shaft by three step cones for 
 i^-inch belt, communicating power to the feed shaft by means of gears with an 
 in-and-out pin. This arrangement gi\-es a roughing and finishing feed for each 
 adjustment of feed belt. The front rest has compound mo\'ement and power 
 cross and angle feed. 
 
 The driving shaft runs at so much higher \'elocit\' than the main spindle that 
 its speed is suitable for polishing while the Lathe is turning. .A steel mandrel 
 and suitable rest are pro\ided for this purpose, and both operations are performed 
 at the same time. 
 
 We build three sizes, as follows: 
 
 40-lNCH Lathe. — Will turn pulleys, etc., from lo to 40 inches diameter, any 
 width of face up to 16 inches. 
 
 50-lNCH Lathe. — Will turn pulle\-s, etc., from 12 to 50 inches diameter, any 
 width of face up to 24 inches. 
 
 60-lNCH Lathe. — Will turn pulleys, etc., from 12 to 60 inches diameter, any 
 width of face up to 24 inches.

 Niles Special Boring Machine. 
 
 PAESIGNED specially for boring pulleys, gears, or other objects — a companion 
 
 machine to our Special Pulley Lathe. The two machines form a set for 
 boring, turning and polishing pulle\'S, that can not be equaled for rapidity and 
 excellence in executing this work. The face plate is revolved b\' powerful gearing 
 driven b}- a cone with six steps for a belt 4 inches wide. The boring bar has 20 
 inches traverse ; has automatic feed and quick return. 
 
 The feeds are operated by belt and have three changes. 
 
 One tool holder, a set of chuck jaws, and a set of special clamps for holding 
 pulleys are furnished with each machine. 
 
 In addition to their value as a special machine for boring pulleys, these 
 machines are adapted to a wide range of work and can be used to very great 
 advantage on a large variety of general machine shop boring jobs. They will 
 accomplish such work vastly cheaper than any lathe. They are in constant use 
 in a large number of shops, working upon almost anything within their range. 
 They will bore cylinders up to 12 inches with all the accuracy, and as quickly, as 
 a special cylinder borer. We consider them among the best labor-saving tools a 
 shop can emplo)^ Setting and chucking work to the horizontal face plate can be 
 done in much less time than on a lathe. We could fill a large volume with 
 testimonials of purchasers who have used them. 
 
 They are built in two sizes : 
 
 50-lNCH Boring Machine. — Swings 50 inches diameter. Will tak-e in work 
 24 inches high. 
 
 60TNCH BORING Machine. — Swings 60 inches diameter. Will take in work 
 24 inches high. 
 
 Countershaft pulleys are 24 inches diameter, 4>^ inches face. 
 
 Speed, 70 revolutions per minute.

 /"ANE man can operate both tlie Turning and Boring Machines. Tlie machines 
 
 are so simple in construction, and so easily operated, tliat tliey do not 
 
 rc^qLiire tlie attention of a skalled meclianic. A man of ordinary intelligence can 
 
 soon be taught to run them successfulK', and get out the full complement of work'. 
 
 We liave actual data (jf work' finished in ten hours on our machines,

 At $2.00 per da\', the labor of boring and turning a 30-inch pulie\' would 
 Cost from ten to fourteen cents. 
 
 An ordinar\' merchantable pulley of this size weighs about 120 pounds. 
 At three cents per pound the casting would cost $3.60. Tak'ing cost of labor 
 finishing, as above, at fourteen cents, and for drilling, tapping and set-screws 
 ten Cents, mak'es the cost of the finished pulle\' $3.84. The list price is $13.00; 
 at 40 per cent, discount the net price is $7.80. Allow a fair amount fur shop 
 e.xpenses and there remains a large margin for profit. 
 
 The aboN'e figures are not e.xceptional, but are a fair statement of the work 
 done on these machines.

 Cylinder Lathe. 
 
 FOR TURNING PRINTING PRESS CYLINDERS. DRY ROLLS OF PAPER MACHINES. AND WORK 
 
 OF SIMILAR CHARACTER. 
 
 /^^F same general construction as our Pullt-N- Lathes. 
 
 Swings 41 inches diameter, and will turn any length up to 7 feet between 
 centers. The machine is provided with two tool carriages moving longitudinally 
 on cross rails on cither side of the machine. 
 
 For turning printing press cxdinders, where a portion of the cylinder is of 
 smaller diameter, a third tool rest, with independent adjustment, is placed on 
 the front cross rail for turning the smaller diameter. This rest is provided with 
 a hinged apron, similar to the tool apron of a planer, and b_\' means of connec- 
 tions to the face plate of the Lathe it is thrown into position for cutting, and 
 withdrawn at the proper time. Thus the entire cylinder is turned at the same 
 time, three tools being at work. 
 
 Power is transmitted through tangent gearing of large diameter and heavy 
 pitch, insuring a smooth, steady motion, free from chatter, a very desirable 
 thing in this class of work. 
 
 Driving cone has six steps, ranging in diameter from 17 to 32 inches, 
 for 4-inch belt. 
 
 The cross rails are set parallel with each other on the bed, and are adjust- 
 able to and from the center for different diameters, being moved simultaneously 
 by screws at each end of the rails, insuring exact parallelism of rails at 
 all times. 
 
 There are four changes of feed, giving ample range for all requirements. 
 
 The entire machine is heavy and substantial, with ample power, and 
 arranged for convenience in operating. 
 
 Countershaft, wrenches, etc., are furnished.

 Gentlemen : — In reply to your inquiry of January 29th, we can say we are more than satis- 
 fied with the 50-inch Pulley Lathe which you sold us. We believe it has more than paid for 
 itself already. This machine and the others which you have furnished have helped materially 
 to strengthen the conviction which we have always held, viz.: That in order to do good work it 
 is necessary to have good tools. The Lathe is especially satisfactory because of the quantity, as 
 well as the quality, of work turned out. Yours truly, SMITH & RICHARDSON.

 Gentlemen : — We have been using your Pulley Boring and Turning Machinery for over a 
 year. We are highly pleased with both machines. After having them once in place it has 
 given us no trouble whatever to operate them — no breakage, friction or other annoyances. We 
 can turn 22 pulleys 18 inches diameter, 634 inches face, in ten hours. The Boring Machine is 
 almost unlimited in capacity. We are highly pleased with the purchase we made of you, and 
 consider it money well invested. Wishing you abundant success, we remain,

 Gentlemen :— Referring to yours of the 6th, would say that the two Pulley Turning 
 Machines, 50 and 36-inch, have been used about four years. Although the works have been 
 running night and day, and all the other tools crowded for all they would stand, we have never 
 been able to keep these machines running full day time. We have no special record of work 
 done on them. They, as well as the ic-foot Boring Mill, have given the very best of satisfaction.

 Gentlemen :— We have had your Pulley Borer and Pulley Lathe in use for some time and 
 can not speak too highly in regard to their construction and efficiency. We have done a large 
 variety of work on them, principally upon the Borer, where connecting-rod ends, eccentrics, 
 couplings, pulleys, pump primers, etc., are bored, and, in fact, anything in which a true hole is 
 desired can be placed on the face plate. On account of the variety of work we have been unable 
 to keep time on any sized pulleys, but we are confident we can bore and turn a pulley in much 
 less time than it formerly took us to chuck one on the boring mill. The pulleys, when bored, we 
 find much truer than when bored and turned on a boring mill, which is of vital importance to 
 engine builders. We do not know how we could get along without the machine were it impossible 
 to get others. They are first-class tools and reflect much credit on the makers. 
 
 Yours very truly,

220 NlLt:S TOOL \\'0[^KS, HA.niLTON.OHIO. 
 
 Part X. 
 Bendino; and Strais-htenino: Rolls. 
 
 \ , /E are tiequently asked fur prices on bending rolls where the width of 
 tlie sheet only is specified. The thickness of plate is also an important 
 factor, as also the diameter of the circle to which it must be bent. 
 
 We make three different styles of hendin/j: rolls, suited to different widths 
 and thickness of plates. 
 
 In the first st\de the machine consists of three rolls. Two of these are 
 placed one over the other and are geared together. The lower roll is adjust- 
 able for plates of different thickness. The bending roll is placed at the back 
 and is moved in inclines in the housings. Both ends are raised and lowered 
 by power at the same time, but one end is adjustable independently of 
 tile other. 
 
 In this arrangement the initial rolls, being geared together, pmch the 
 sheet tightl)' and carry it through without slippage. 
 
 One bearing of the upper roll is movable, and may be thrown back to 
 remove flue rings. 
 
 We recommend this form of rolls as most desirable for bending light 
 boiler plate and tank' iron, but the adjustability of the feeding rolls for different 
 thickness of plate must be small on account of their being geared together. 
 
 In the second style of construction, which we employ for the wider and 
 heavier range of plates, the machine consists of three rolls placed in pyramid 
 form, with the two lower rolls geared together, and the bending roll on top, 
 which runs by friction. 
 
 The upper roll is raised and lowered by power to suit the thickness of 
 plate or diameter of bend. It is operated in the same manner as the back roll 
 in the first style. 
 
NILES TOOL WORKS. HA/niLTON. OHIO. 221 
 
 In this construction, also, one bearing of tiie upper roll is movable to 
 permit the removal of rings. 
 
 This form of rolls is preferable for wide plates of medium thickness. The 
 weight of the plate is generally sufficient to drive the upper roll. 
 
 For bending the heaviest class of plates, such as are used in ship building, 
 we recommend use of four rolls. In this construction two rolls are placed one 
 over the other, are adjustable by power for thickness of plate, and both are 
 driven. The bending rolls are placed one on each side and move in inclined 
 ways in the housings. They will curve the sheet almost to the edge, leaving 
 only a short straight end.

 No. 10 Power Bending Rolls. 
 
 FOR SHIP PLATE. 
 
 \ . /ILL bend plate iron up to i ;^ inches thick', and 16 to 22 feet long. 
 
 This machine has four rolls — two central rolls, one placed above the other, 
 and two side rolls moving in inclines on either side, adjustable to suit the 
 diameter to be bent. 
 
 The rolls are all solid wrought iron forgings. Tlie center rolls 26 inches 
 diameter, the side rolls 22 inches diameter. 
 
 The center rolls are dri\'en by a pair of re\'ersing engines, running them 
 in either direction. 
 
 The side rolls are raised and lowered by an independent reversing engine. 
 These rolls may be operated together or separately, or either end of either 
 roll may be raised independentl)', as may be required. 
 
 The housings supporting the rolls are very strong and substantial. The 
 journal bearings of the rolls are of very large diameter and fitted into bearings 
 set into the housings. 
 
 The entire machine is mounted on a very heavy sole-plate provided with 
 anchor-bolt holes to secure it to the foundation. 
 
 The machine will bend ship plates, curving them in any manner required, 
 and has ample power and strength to do the work expeditiously. 
 
 A machine constructed in this manner, with four rolls, curves the sheet 
 almost up to the edge, leaving only a short straight end. This is specially 
 important when working heavy plates such as the machine will bend. 
 
 The machine is intended to be set in a pit, upon a solid foundation. All 
 reversing and operating levers, etc., are brought above the floor line, which 
 should be about the height of the cross t^irt.

 No. 12 Power Bending Rolls. 
 
 FOR SHIP PLATE, 
 
 nnmS machine is 22'^ feet between the housings, and will bend plates up to 
 
 2 inches thickness. It is similar to No. 10 machine, shown in cut on 
 P'A'fSy 228. 
 
 This machine has four wrout^ht iron, forged rolls 22_54 feet long between 
 journals, supported in two massi\'e housings. 
 
 The two feeding rolls are placed x'ertically one over the other. They are 
 32 inches in diameter. 
 
 The two bending rolls are placed one on each side of the center rolls. 
 These are 25^2 inches in diameter and move in guides in the housings. They 
 are so placed as to move very closely by the lower center roll when the latter 
 is touching the upper roll. 
 
 The upper feed roll runs in fi.xed bearings in the housing. 
 
 The lower roll runs in bearings having a vertical adjustment of 5 inches, 
 obtained by means of heavy steel adjusting screws 8 inches in diameter, 
 operated b)' tangent gearing. 
 
 The bending rolls ha\'e an adjustment of 20 inches. When in their lowest 
 position the upper surface is 4 inches below the bottom of the upper feed roll, 
 fr(jm which position the\- mo\-e upward until the\' touch the upper feed roll. 
 
 The adjusting screws for these rolls are of steel, 7 inches in diameter, 
 and are operated by tangent gearing. 
 
 The two bending rolls and the lower feed roll are raised and lowered by 
 a pair of reversing engines which are used for this purpose only. 
 
 Clutches are provided in the train of elevating gear for all the movable 
 rolls, so that either one or both ends of any of them can be moved independenth'. 
 
 Safety friction clutches are provided in the gear train of the lower feed 
 roll, which allow the gearing to slip when the feed rolls and plate are pressed 
 tightly together. 
 
 Graduated index scales are provided to indicate the exact height of 
 the ends of the rolls. 
 
 The two feed rolls are positively geared together from opposite ends. 
 Main gear on each roll is 10 feet diameter, 15 inches face and 5 inches pitch.

 Plate Straightening Machine. 
 
 'T~"HIS machine is designed for straightening plate iron for boilers, tanks, safes, 
 
 and all other purposes. Such work can be done on this machine perfectly, 
 and at a great saving of labor and expense. 
 
 The machine has seven rolls arranged in two tiers — four rolls in the upper 
 tier and three in the lower. 
 
 The lower rolls are driven by steel pinions. 
 
 The upper series of four rolls are adjustable vertically to suit the thickness 
 of sheet to be straightened. Indexes are provided for setting these rolls. The 
 outer rolls of this series are adjustable independently, the inner rolls are raised or 
 lowered together, and the entire four rolls are also arranged so that, after being 
 once set, they may all be adjusted at the same time without disturbing their 
 relative positions. 
 
 All the rolls are steel forgings, of sufficient size to prevent spring. They run 
 in journal bearings of large size, carefully fitted to the housings. 
 
 The machine is carried on a base plate, tying it together and therefore 
 requiring but slight foundation. 
 
 Driving pulleys are arranged for straight and cross belts, to run the rolls in 
 either direction. 
 
 We build a number of sizes for straightening plate from No. 16 to i inch 
 thick, as given in the following list: 
 
 No. I. — Diameter of rolls, 6-'= 3 inches. Length of plate 42 inches. Thickness 
 of plate, from No. 16 to /^-inch. 
 
 No. 2. — Diameter of rolls, 638 inches. Length of plate, 60 inches. Thickness 
 of plate, from No. 16 to 54 -inch.

 Gentlemen : — We haxe had in use for the past year, a set of your Power Bending Rolls for 
 10-foot sheets, driven by a pair of engines wJiich we run independent of our shop engine. The 
 rolls run very nicely and are the best bending rolls 1 ever saw. JJiey do tlieir work \ t;r\' accu- 
 rately and are easily regulated by the engines, both in driving the mach.ine and in setting the 
 bending roll. I prefer this style of rolls to the pyramid rolls, for the reason that we can regulate 
 the initial rolls to the thickness of plates and do our work very much faster, as the rolls prevent 
 the plates from slipping. We are well pleased with the rolls and would not part with tliem for 
 any price if we could not replace them. Yours truly, JOS. F. Wangler.

 Gentlemen : — The 16-foot Boiler Rolls furnished us by your company ha\e been in use more 
 than two years and have been perfectly satisfactory. We have rolled a great number of c\'linders 
 for corrugated flues and a variety of work on them, unshipping the work with great facility. 
 We can further say that the 8-foot Rolls of your make turn out excellent work.

 Gentlemen: — In answer to your inquiry of how we like the 16 foot Rolls furnislied us in 
 August, 1887, we wish to say that they are just what our superintendent wants for ship yard 
 work. We have had no trouble with them and have done a great deal of work on them, rolling 
 plates from the thickest to the thinnest. They are economical in handling, and we can turn out 
 as accurate work on them as any Rolls we have ever used.

 Gentlemen :— Yours of the i6th inst. received. We take pleasure in answering same. The 
 Plate Planer furnished us some twn years ago has been in constant use e\'er since and has gi\'en 
 us the best of satisfaction in every particular. We highly recommend it, and cdiisider it tlie best 
 tool of its kind in the market. The large 17-foof Rolls have now been in service for the past six 
 years, and we have bent and rolled all thicknesses and sizes of plates in the most satisfactory 
 manner. All the parts are durable and well n/ade and we feel pleased in ever\' way. We beg 
 leave to remain. Yours very truly, JOHN MOHR & SON.

 Gentlemen : — Replying to your favor of the 26th inst., it gives us pleasure to state that the 
 Bending Rolls furnished by you in 1887 have, in every way, proved satisfactory. 
 
 Yours truly, HENRY WARDEN. 
 
 John O'Brien Boiler Works Co. 
 Niles Tool Works, Hamilton, O. ST. LOUIS, MO., Feb. 17, 1891. 
 
 Gentlemen : — In reply to your inquiry in reference to tlie Bending Rolls you furnished us in 
 1888, we are glad to say that they are working very satisfactorily, enabling us to turn out our 
 product rapidly and in good shape. By means of the pair of independent engines which you 
 supplied with the machine, its operations are easily and quickly controlled, thus doing away with 
 all countershafting and belting, and the rolls are set with the power of the engines instead of tlie 
 old style of using the "wrench" in adjusting them. In our machine, the initial rolls are placed 
 one above the other and geared together. The power in driving the plate through is thus made 
 positive, and the rolls pinch the sheet close to the edge, carrying it tlirough without slippage. 
 The bending roll is placed at the back, moving in inclines in the housings to suit the curve 
 desired in the sheet to be bent. We think this machine is much better for light plate than that 
 where the initial rolls are placed on a level and a third roll placed over the space between them, 
 as on our machine light plates are carried through at a uniform speed, which we do not think 
 could be attained without having the rolls between which the plate passes, geared together. We 
 ha\'e bent plates i inch thick and 12 feet wide to a circle 30 inches diameter at one pass. We 
 can, therefore, cheerfully recommend this style of rolls to any parties wishing to buy. 
 
 Yours truly,

 Grindstone Box. 
 
 ( Improved Pattern.) 
 
 TO TAKE A STONE 4 FEET DIAMETER AND 8 INCHES FACE. ESPECIALLY DESIGNED 
 
 FOR MACHINE SHOPS. 
 
 n^HERE is no implement more frequently used in a machine shop than a 
 
 grindstone, and if it is not kept in good condition the consequences are 
 imperfectly ground tools and poor work. 
 
 We illustrate a bo.x that will correct all the evils incident to the frames 
 commonly used, and insure the stone being kept in good trim with only 
 ordinary care. 
 
 The stone is hung on a square wrought iron arbor, and secured sidewise 
 by large nuts and flanges. 
 
 The bearings are large and self-oiling. They will run without attention 
 for weeks. 
 
 The grinding rest permits the water running over it to return to the trough. 
 
 When the stone becomes smaller, and a change of pulleys is necessary to 
 keep up the speed, the belt need not be cut, but, instead, the box may be 
 moved a few inches to accommodate the change. 
 
 When sediment collects the box may be wheeled to the door, the hand-hole 
 plates removed and the box slushed out. 
 
 This box will keep your shop neat and tidy, and you will avoid having a 
 mess of sand and water trickling through from one floor to another. 
 
 The trough is a single, handsome casting. 
 
 Complete weight, 900 pounds.

 Shaft Straightening Machine. 
 
 ' I 'HIS machine was desiy;ned to met-t our own need of a machine which 
 would do away with flie nuisance of strai,t;htening heavy shafts in 
 tiie lathe by means of the ordinary screw press sliding on the ways. 
 
 Its main features a're a lon,L,s stiff bed carrying at intervals roller 
 tables which are driven by power. On these the shaft is re\'olved to 
 test its truth. On the bed is also mounted a heavy, slidin;j; carriage, 
 adjustable to any required position on the bed. On this carriage is 
 mounted a ram, or plunger, which is driven by a cam through the means 
 of a spur gear and pinion, and splined shaft communicating power from a 
 driving pulley at one end of the machine. This ram is adjustable by a 
 screw operated by a large hand wheel. 
 
 in operating, the shaft is first revolved to indicate the crool\ed places. 
 The carriage is then adjusted to suit these places, which are then straight- 
 ened by the ram. Both the roller carriages and the ram are under easy 
 control of the operator in any position.

 Hydrostatic Forcing Press. 
 
 F^OR forcing on to their sliafts cranl<s, gears or pulleys, and any other 
 
 similar work. 
 
 It can he used for forcing mandrels into work to he turned, and for 
 a great variety of purposes about any machine shop. 
 
 It insures a perfectly tight fit, prevents bruising the work, and performs 
 the operation in the shortest possible time. 
 
 Any required pressure from i to 150 tons on the ram may be exerted. 
 
 The Press is similar in general construction and operation to our Car 
 Wheel Presses, heretofore described. 
 
 Two pump plungers are used, the operation of which is controlled by 
 our patented device. 
 
 The ram is g inches diameter. Cylinder is made of cold-blast iron 
 and is copper lined. The strain is taken by wrought iron tie bars of 
 ample strength. Clearance between tie bars, 48 inches. 
 
 Resistance post has an opening to admit a shaft 14 inches diameter. 
 Greatest distance between ram and resistance post, 14 feet 2 inches. 
 
 The advantages of such a machine in engine shops, or general machine 
 shops, are numerous, and its use will give better work at reduced cost.
