NEW YORK CHICAGO PHILADELPHIA Catalog K112 CORBIN HARDWARE T HE TERM “Corbin Hardware” covers the most comprehensive and best assorted line of locks and finishing hardware made. Every article has been subjected to rigid tests, both as to its quality and finish and its desirability from the cus¬ tomers’ view point, and in consequence the name of Corbin carries with it a sense of superiority and desirability. The name is a guarantee of excellence. From time to time, Corbin inventors have de¬ veloped specialties which have shown so great an improvement over anything then in existence as to warrant special mention and a special regard in the esteem of those who erect and equip buildings of the finest types. This book is devoted to some of the newest and most important of these specialties and you will find its pages well worth a careful reading. P. & F.

BOTTOM-HINGED TRANSOMS ARE GEN¬ ERALLY USED, AS THEY DEFLECT THE INCOMING CURRENTS OF AIR UPWARD AND AWAY FROM THE OCCUPANTS OF THE ROOM. No. 075 FOR BOTTOM - HINGED TRANSOMS For instructions for ordering, see page 15. Characteristics of the Corbin Concealed Lifter The only portion visible is the bronze metal T handle and plate, which can be finished to correspond with the other hard¬ ware. It is noiseless in operation, never wears out or gets out of order, requires no adjustment after being installed and costs nothing for upkeep or repairs. It is equally applicable to steel or wood trim, and can be used in partitions as thin as two inches. It will operate any style or size of transom, whether bottom, center or top hung, right or left hand, swinging in or out. It is therefore adapted to suit the swing of the door, or other conditions of use or construction. For description Operation Fig. 1 NO. 075 CONCEALED TRANSOM LIFTER IN POSITION FOR USE. of mechanism, see page 10. Turning the T handle operates any of the Corbin concealed transom lifters. The handle turns easily, only one hand being required to open or close a transom. The leverage gives a powerful and positive action, and the mechanism is so arranged that the transom is firmly held in any position, obviating the use of catches or other locking devices. (Continued) THE CORBIN CONCEALED TRANSOM LIFTER Fig. 4 __ TYPICAL CORRIDOR OR ROOM DOOR WITH CENTER-HUNG TRANSOM OPERATED BY A NO. 074 LIFTER. THE CENTER-HUNG TRANSOMS ARE BEST ADAPTED TO UNUSUALLY TALL, LARGE OR HEAVY SASH, AND FOR WALL TRANSOMS SUCH AS APPEAR IN FIGURES 7 AND 8. THE CORBIN NO. 074 LIFTER WILL GOVERN PERFECTLY THE ACTION OF CENTER-HUNG TRANSOMS OF ANY SHAPE, SIZE OR WEIGHT. No. 074, FOR CENTER-HUNG TRANSOMS For instructions for ordering, see page 15 (Continued) An oiling tube is provided, so that the mechanism in the gear case may be lubricated with an ordinary oiler without removing or disturbing any of the parts. Mechanically Correct Every care has been taken, both in design and construction, to give the maximum of efficiency. The mounting of all parts on a single back plate ensures the proper operation and freedom from For description binding.

THIS IS ATTACHED THE SAME AS NO. 075, EXCEPT THAT IT IS RAISED TO BRING THE PIVOT OPPO¬ SITE THE CENTER OF THE SASH AND A DIFFERENT SASH PLATE IS USED. Since all the mechanism is attached to a single back plate and as a unit, the Corbin Concealed Transom lifter is both easy to install and certain to operate satisfactorily. The usual blocking is not interfered with. The lifter should be applied on the side of the door next to the lock so as not to interfere with the buck and jamb on the hinge side. Figures 13 and 14 illustrate the best form of the buck, but if not so made, it can be easily cut so as to per¬ mit the insertion of the gear case and pivot levers. Instructions for applying are packed with each lifter. (Continued) 7 THE CORBIN CONCEALED TRANSOM LIFTER NO. 0 7 3 CONCEALED T RANSOM LIFTER I N POSITION FOR USE.

For descrip¬ tion of mechan¬ ism, see page 10. TYPICAL CORRIDOR OR ROOM DOOR IN A HOTEL OR OFFICE BUILDING, WITH TOP-HUNG TRANSOM AND NO. 073 LIFTER. TRANSOMS HINGED AT TOP ARE NOT GENERAL¬ LY USED, BUT NO. 073 LIFTERS WILL FILL EVERY RE¬ QUIREMENT OF SERVICE WHEN THEY ARE EMPLOYED. No. 073, FOR TOP-HUNG TRANSOMS For instructions for ordering, see page 15. (Continued) Its Economic Value The value of a transom for ventilation depends absolutely upon the device that operates it. If the transom is hard to open or if the lifter is broken or out of order no attempt is made to secure ventilation through this means and the transom is use¬ less. Therefore, it is most important that the transom lifter be easily operated, thoroughly reliable and, because of the number employed, that it should require no attention and should last as long as the building does. The Corbin concealed transom lifter has all the desired characteristics and. further, it possesses them in a degree to be found in no other device for governing transoms, and has some features which are not found elsewhere. The transoms of a large building, properly equipped, will give better ventilation than any system of forced draught for the halls and corridors from natural flues through which the warm air of the rooms seeks to escape, causing a strong current whenever an opening is found through which the air can pass. The health and comfort of tenants, and the desirability of rooms is materially affected by the quality of the air and possibility of arranging for free currents when desired and perfectly controlling them. Hence the necessity for such a device as the Corbin Concealed Transom lifter, especially designed forservice under all conditions. Fig. 5 L 8 THE CORBIN CONCEALED TRANSOM LIFTER Fig. 7 A No. 074 transom lifter attached to three parallel transoms in corridor of an office building. The easy and positive action makes it possible to operate any number of transoms hung in this way as easily as one. Fig. 8 A No. 074 Transom Lifter attached to a three-section tran¬ som in the corridor of an office building. The three sections move as one and are as easily and positively governed as a single sash. Any number of transoms placed perpendicularly to one another can be operated with the Corbin Concealed Transom Lifter. 9 This shows the T handle and the front of gear case broken away to expose the mechanism. The T handle and plate are the only visible portions, the balance being mounted within the casing. The toothed segment attached to the worm spindle gear per¬ mits an adjustment that will place the handle in the center of the casing. The worm gear multiplies the leverage and enables the transom to be moved with little pressure on the handle, and also holds the transom firmly fixed at any angle. The rack moves up and down as the handle is turned, actuat¬ ing the transom. Fig. 9 This shows the back of the gear case, with the assembly plate removed. The ball-tip oiler protrudes through the jamb. Pressing the spout of an or¬ dinary oiler against the ball causes it to recede, opening the tube for admission of lubricant. The two bolts pass through the jamb and attach the lifter firmly to it. These bolts are located outside of the door stop on the jamb. The rack and gear are shown where cover is broken away. The rack is moved up and down as the gears are rotated by the turning of the handle. Fig. 10 10 THE CORBIN CONCEAL E_D TRANSOM LIFTER Figure 11 illustrates the upper end of the lifter and shows the compound lever, which gives a powerful action in a small space. The arrangement of the parts is different in No. 073 from that in Nos. 074 and 075, in order to reverse the movement, but the same parts and the same effect obtains in all. The sash plate, with the noiseless slide, raises and lowers the transom without jar or noise. Fig. 11 Figure 12 illustrates the hinged lower end of the con¬ necting rod, and shows the means by which a direct pull upon the compound lever is obtained without affecting the action of the rack and gear. This provision ab¬ solutely prevents any possibility of sticking or binding. The spring absorbs any back-lash. Fig. 12 THE CORBIN CONCEALED TRANSOM LIFTER Figure 13 shows a horizontal section of a typical wood jamb, at the gear case, which is usually located about four feet from the floor line. It is necessary to set the buck back from the jamb ^ inch. This does not interfere with the usual blocking between the buck and the jamb. A notch 3f inches in height by lfxlF inches horizontal must be cut in the buck, which will give ample space for the insertion of the lifter. The T handle is located on a flat surface of the casing. The construction of the gear case, as shown in figure 9, permits a wide range of adjustment to fit different widths of casing. The screws for attaching the lifter to the jamb are shown in figure 10. 1figure 14 shows a horizontal section of the same trim shown in figure 13, but taken at the pivot point of the transom sash. 1 he buck must be set | inch from back of jamb on the lock side of the door, as ex¬ plained above. The construction on the hinged side of the door is not affected. The sash may be pivoted at bottom, center or top and open to any point up to 45 degrees. Complete details will be furnished for installation. Fig. 13 Fig. 14 12 THE CORBIN CONCEALED TRANSOM LIFTER Fig. 15 Figure 15 represents a two inch plaster wall with a split jamb. The section is shown at the gear case, located approximately four feet from the floor on the lock side of the door. The jamb is 3 T 3 g inches in width. Any width less than this makes the use of a concealed transom lifter impossible on this particular construction The gear case and all other parts are standard. —,/jv-— hvy//, a#; :.: y frsV. J/Vw.

This shows the pivot bearing and a ljj inch transom, which may be hinged at top, center or bottom as may be desired. The two inch wall is the latest de¬ velopment in modern design of buildings, and the Corbin concealed transom lifter is the only device which can be used on the limited space which the narrow con¬ struction affords. 13 THE CORBIN CONCEALED TRANSOM LIFTER Fig. 17 Figure 18 repre- sents a horizontal section of the same jamb shown in figure 17, but taken at the pivot bearing. The transom may pivot at any point and will open to 45 degrees. Figure 17 represents a horizontal section of a jamb with metal trim, taken at the gear case, located about four feet from the floor. A four inch tile section is shown with marble on the cor¬ ridor side and metal trim on the room side. If desired, the assembly plate of the Corbin con¬ cealed transom lifter may be spot welded to the metal jamb, but it is preferred to weld a } inch plate at intervals to the metal jamb to re¬ ceive the screw heads for holding the device in place.

TO DETERMINE THE HAND OF A DOOR The hand of a door is always taken from the outside of a street door, from the corridor side of a corridor door and from the side of a communicating door between rooms on which the butts do not show when closed. If the butts are at the right hand: A door opening from you is right hand, regular. A door opening toward you is right hand, reverse bevel. If the butts arc at the left hand: A door opening from you is left hand, regular. A door opening to¬ ward you is left hand, reverse bevel. SAMPLE SPECIFICATION The contractor shall furnish and install for all movable transom sash, concealed lifters, the lifter to be attached to the back of the jamb, and to be operated by a T handle placed on the face of the trim or casing. The transom will be hinged in the regular manner. The device will be self-locking in all positions and will open transoms to any point up to 45 degrees, holding them locked wherever left. It will be opened and closed by means of a T handle, no chains, hooks or other parts being required. The lifters will be manufactured by P. & F. Corbin, New Britain, Conn., who will furnish details with instructions for applying this hardware. 15 THE CORBIN CONCEALED TRANSOM LIFTER Fig. 20 PARTS OF CORBIN CONCEALED TRANSOM LIFTER Number Description Number | Description A Inside Pivot Crank V Clamp Bolt and Worm Bearing B Outside “ w Connecting Rack Gear C Compound Lever X Worm Spindle D “ Link Y T Handle Spindle Gear E “ Stud Z T Handle F Pivot Bearing Z1 Rose for T Handle G and Gear Case Screws ZZ Washer for T Handle Spindle H i HI $ Compound Lever Stud AA AA1 Sash Plate Steel Back Plate I “ Screw AA2 Spring J Washer for Gear Case and Studs AA3 Plate K Pivot Crank Connection AA4 Steel Sash Plate Slide K1 Inside End BB Compound Lever Connecting Link Pin K2 Outside End CC Connecting Link Pin and Rack L Pivot Crank Screw DD Sash Plate Stud M Oiler DD1 Screw for Sash Plate Stud Ml “ Ball DD2 Washer “ “ M2 “ Tube DD3 Pivot Pin M3 “ Spring EE 8-32 Gear Case Screw N Connecting Rod Rack FF Snap Ring for Studs O “ Link GG Coil Spring P “ Guides HH Hook for Coil Spring Q “ Link Connection II Off-End Pivot Bearing for 074 Lifter R Gear Case IJ Pivot for 074 Lifter, for ljin.

It is the solution of the problem of how to satis¬ factorily handle casement windows where comfort, quietness, and ease of manipulation are desired. Figure 1 shows the operator with all parts in position as in use. The actuating mechanism is simple, consisting of a worm and gear, greatly multiplying the leverage and enabling a child to open or close any window with ease. Windows which stick from paint are easily forced loose. The most severe wind storms neither move the sash or make it difficult to move. The window is governed easily under all conditions by the use of the handle and cannot be moved except by the handle, being securely locked in any position in which it may be placed. Figure 2. The No. 60 Casement Operator Applied. THE CORBIN CONCEALED CASEMENT OPERATOR The gear ease is made to retain lubricant. A screw hole plainly marked “oil” permits lubrication. Vase¬ line, with a small quantity of flake graphite, well mixed, is the best lubricant, although oil or heavy grease can be satisfactorily substituted. The exterior parts are galvanized. The gear is accurately machined from a high grade bronze casting, and the worm is made from steel, ensuring good wearing qualities and ease of operation, and making it impossible for the two parts to be fastened together by corrosion. The sash plate is also shown attached to the bottom of the casement, broken away to show the bronze slide on the end of the pivot crank, which slides easily in a finished slot in the plate as the handle is turned and the window is opened or closed. It is not necessary to place the casement operator so that the pivotal center coincides with the hinge center of the casement, the slide in the sash plate per¬ mitting the sash to swing freely without binding. Figure 3 shows a pair of case- Figure 2 shows the casement operator applied, the window stool and apron being broken away to show the gear case, the pivot bearing, and the pivot crank. The bolts,which hold the gear case in position are also shown. These pass upward through the wood sill and hold the case securely in position un¬ der the window sill where it is entirely enclosed and protected from the weather. ment windows fitted with two Corbin Concealed Casement Op¬ erators. When the windows are closed the only parts that are visible are the crank handles and escutcheons which are unobtru¬ sive and out of the way. Figure 3. A pair of Casement Windows equipped with No. 60 Corbin Concealed Casement Operators. The handles and plates can be finished to match the other hardware used. When the projection of the stool interferes with the use of a crank, a tee handle is provided. If so ordered, the handles can be made de¬ tachable, so that only the roses are seen—a valuable feature when it is desired to have one person control the opening and closing of the window. THE CORBIN CONCEALED CASEMENT OPERATOR PLAN VIEW ELEVATION Figure 4. Details of Application. When ordering, the dimensions at A, B and C should be given. The No. 60 Casement Operator is not difficult to apply. It should be put in place before the apron and stool are attached and a few simple rules for properly installing it should be carefully observed. It can be used with any detail of sash and sill and will give perfect service without adjustment after being properly applied. The gear case must be set with the top plate level. If the bottom of the sill is not level, a wedge of the proper size should be inserted between the sill and the top of the gear ease as shown in Figure 4. The position of the gear case can be varied to suit the construction of the sash and sill, but its center should never be more than inches at D of 4j>4 inches at E as indicated in Figure 4. These figures mark the extreme limit at which the arm will make proper connection with the sash plate to get the desired free action. Ordinarily, the center of the gear case is placed 2 inches from the jamb, and 1^2 inches from the stop, and these figures should be used when possible. When the stool extends over the top of the gear case, the under side of the stool should be cut away, as shown in Fgure 4, in order that the arm may move freely. Full instructions for application are packed with each Casement Operator. The Corbin No. 60 Concealed Operator is the most reliable device made for controlling the action of casement windows. There are no parts that rattle; none that have to withstand undue strain and wear; none that are affected by use or weather. The worm and gear so reduce the effort required to open and close the window that a child can operate it with ease. MADE ONLY BY F. & F.

K. 27 ITY THE CORBIN CONCEALED CASEMENT OPERATOR (PATENTS APPLIED FOR) 31 THE CORBIN CONCEALED CASEMENT OPERATOR FOR WINDOWS OPENING OUTWARD NO. 60 CONCEALED CASEMENT OPERATOR IN USE This device permits the opening and closing of casement windows without interference with curtains or window screens. It locks the sash securely at any point from closed to wide open, making catches or sash locks unnecessary. It presents no protruding bars or braces; employs no thumb screws, requires no effort to operate and never gets out of order. It is the solution of the problem of how to satisfactorily handle casement windows in fine residences, where comfort, quietness and ease of manipulation are desired. Figure 58 shows the casement operator applied, the window 'stool [and apron being broken away to show the gear case, pivot bearing and pivot crank. The bolts which hold the gear case in position are also shown. These pass upward through the wood sill and hold the case securely in position under the window sill where it is entirely enclosed and pro¬ tected from the"weather. l'he gear case is constructed so as to retain lubricant. Provision is made for lubrication when desired. The illustration also shows the sash plate attached to the bottom of the casement sash, broken away to show the bronze roller on the end of the pivot crank, which slides easily in a finished slot in the plate as the handle is turned and the sash is opened or closed. Fig. 58 32 THE CORBIN CONCEALED CASEMENT OPERATOR Fig. 59 A PAIR OF CASEMENT WINDOWS EQUIPPED WITH No. 60 CORBIN CONCEALED CASEMENT OPERATOR The casement operator can be used upon either right or left hand windows by a simple reversal of parts, which can be easily made when the device is applied. It can be supplied for casements opening inward when desired. The actuating mechanism employed consists of a worm and gear greatly multiplying the leverage and enabling a child to open or close any window with ease. Windows which stick from paint are easily forced loose. The most severe wind storms neither move the sash nor make it difficult to move them. The window is governed easily under all conditions by the use of the handle and cannot be moved except by the handle, being securely locked in any position in which it may be placed. Figure 59 shows a pair of casement windows fitted with two Corbin concealed casement operators. It will be seen that the only parts visible are the crank handles and plates, whether the windows are opened or closed; these can be finished to match the other hardware used. If desired the handles can be made detachable so that only the roses are seen. 33 THE CORBIN CONCEALED CASEMENT OPERATOR Fig. 60 VERTICAL SECTION SHOWING POSITION OF CASEMENT OPERATOR Figure 60 is a vertical section through the window sill and stooling, showing the gear case, the worm gear, the vertical connection to the pivot arm and the sash plate attached to the bottom of the window. The spindle may be of any length to suit the conditions of use. The thickness of the sill may measure from If to 4 inches in length, varying by f inch. The casement sash shown in Figure 60 is If in., the size most generally employed. Plates can be sup¬ plied for other thicknesses, from If to 2 \ inches. A screw-hole, plainly marked “oil’’ permits lubrication. Vaseline, with a small cpiantity of flake graphite well mixed, is the best lubricant, although oil or heavy grease can be satisfactorily substituted. 1 he exterior parts are galvanized.

The handle and rose on the apron of the window are the only visible parts. It is made in two forms as described below. In No. 063 a worm and gear mechanism is employed. This makes the shutter worker very easy to operate and also serves to lock the shutter firmly at any point, so that it is not affected by the action of the wind and making it unnecessary to use any other fastening to hold the shutter in either the closed or wide open position. The mechanism is finely and accurately made, ensuring perfect action. All exposed parts are heavily galvanized. In No. 064 a spiral gear and pinion are provided which give the same easy action and hold the shutter fast in either a closed or wide open position only. It will remain stationary in other positions under ordinary conditions and if a gust of wind closes it or throws it wide open it is firmly locked and banging is made impossible. This is accomplished by a locking device in the rose. When desired the rose can be supplied with intermediate locking points but unless otherwise specified will lock only in the wide open or closed positions. 38 THE CORBIN CONCEALED SHUTTER WORKER A PLAN SECTION OF DOUBLE BLINDS Figure 63 is a plan section of double blinds, showing the location of the shutter workers and the necessity for specifying the hand desired. If it is desired to use a folding blind hinged in the center, we can supply a fixture to meet the different conditions which will ensure the automatic action of the tree section, bringing it to its proper place, fully extended when the blind is closed and holding it folded close to the hinged section when the blind is opened. r~ THE CORBIN CONCEALED SHUTTER WORKER Fig. 64 Figure 64 is a section of the sill showing spaces for sash, screen and blind. It will be seen that the shutter worker is screwed fast to the outside of the sill with a curved pivot arm extending under the blind and engaging in a groove in the sash plate, the crank handle spindle extending through to the face of the window apron on the inside. j^lipd Operj Fig. 65 Figure 65 is a horizontal jamb section of the shutter worker showing the blind in a closed position with lines to indicate the position when open. The operating crank may vary in length to suit operating conditions. 40 THE CORBIN CONCEALED SHUTTER WORKER Fig. 66 The foregoing list of parts is furnished as a guide to ordering if any portion is lost or damaged in handling previous to being applied to the window. After it is in use there will be no breakage or need of new parts. INSTRUCTIONS FOR ORDERING Furnish a full-sized section as shown in figure 64. There must be at least If inches from the storm sill to the top of the wood sill or the bottom of the blind. Gear cases BW1 and BW2 have flanges 1£ inches in height where they screw to the sill. The crank handle spindle comes in the center of the flange and the full- sized section of sill serves to locate the crank spindle and rose. 41 Fig. 67 I he out fit consists of a hook pull,^ mortise latch, with rose and push button and an adjustable stay. It is used in connection with shutters especially constructed for blind awnings, the lower section of slats being fitted to a separate frame hinged at the top. lo open, pressure on the push button withdraws the latch bolt, when a gentle push on the blind tilts the movable section to the desired angle. The friction of the slide in the stay is so adjusted that it will hold the awning section in any position against any wind pressure. To close, simple insert a finger in the hook pull and draw the awning section to a closed position. 42 THE CORBIN BLIND AWNING FIXTURE Fig. 68 No. 211134 Shutter Pull CAST BRONZE SIZE 1 x 1§ In.

The No. 64 latch is supplied with a push button and is so constructed that a light pressure upon the push button withdraws the latch bolt. The action is quick, lively and positive. Flat front and strike can be furnished instead of rabbeted if desired. The No. 0198§- friction stay joint consists of a U shaped channel which is screwed to the jamb. A spring block slides therein and is connected to a steel arm which is provided with a fastening for either the edge or face of sash as desired. When used as in Figure 67 it is practically concealed when the sash is closed; when attached to the face it is entirely exposed. 43 THE CORBIN UNIT LOCK Fig. 71 LOCK COMPLETE SHOWING INTERIOR MECHANISM This lock possesses a number of advantages, the value of which is readily recognized. 1. It is made in a unit, sold as a unit and applied without detaching any parts. The architect and owner can be shown the lock just as it will appear in use and there is no possibility of loss of parts or of disturbing the adjustment made at the factory. 2. All the moving parts are attached to and contained within a solid cast frame. This makes possible a nicety of adjustment and close fit which eliminate looseness and rattling. A play of .004 inch in the knob gives a smooth positive action and a rigidity and strength not obtainable with other locks. The swelling and shrinking of doors cannot affect the action. 3. The Corbin Pin Tumbler Cylinder is employed mounted in the knob, where it can be found with ease in the dark. The cylinder has all the features described on page 49 and its location commends it to the favor on sight. Its advantages need no com¬ ment. 4. The knobs have screwless spindles and never work loose. They have the easy smoothness of action of the knob of a safe- lock. One-eighth of a turn operates the lock. 5. The form permits the use of the most improved mechanism. This includes broad, heavy latch bolts of the swinging type, impossible in thin lock cases, with a long throw, making it cer¬ tain that the latch enters the strike, a direct pull on the latch bolt reducing the friction and giving a lively action with a resili¬ ent spring, and the use of a very few parts of simple construction making the lock very strong and not affected by wear or abuse in use. 44 THE CORBIN UNIT LOCK 6. It is easy to apply, the cut in the edge of the door being made by saw and chisel, only ten minutes being required to attach a lock. If desired, the doors can be cut at the mill, obviating any danger of injury to finish when attaching the lock. The heavy cast escutcheons make the door stronger at the lock than at any other point. Inside Knob and Locking Ring 7. The protected box strike prevents any possibility of burglarious attack from the face of the lock 8. Locks of different functions cover all modern requirements completely and fully. Note the list on page 47. Fig. 74 Outside Knob and Cylinder 9. The locks are adjustable to doors of all thicknesses. I hey are reversible for right and left hand except when the ornamentation of the escutcheon prevents reversing. They are supplied in all designs of Corbin hardware. Fig. 75 Easy Swinging Latch and Roll Backs 10. I hey are thoroughly reliable. Their value is recognized where the highest possible degree ol quality and security is desired. They have been placed in fine buildings for fourteen years and the first locks produced are giving perfect service to-day. A list of buildings of national repute will be supplied on application.

It has all the advantages to be given by any other cylinder and a number not to be obtained elsewhere, and can be used where any other cylinders are employed. The key-way has projections on both sides which reach the center, making it impossible to insert a flat picking tool or to use any other than a Corbin key of the proper class. The key plug is turned by the key and carries the lever which throws the bolt. It is cut from a solid cylindrical bar, and the key-way is cut into it by special machinery of great accuracy. It is released by the service key. The master ring is a Corbin invention and is found alone in Corbin cylinders. It provides a new point for the release of the key plug and in effect gives two locks in a single case, each perfectly independent of the other, so far as key changes are concerned. The master key releases the key plug and the master ring, which rotate together. It is thus possible to have the service keys of a number of locks all different but to have the cylinders so made that the same master key will unlock them all. The convenience and reliability of the Corbin master-keyed cylinder as compared with two cylinders or one cylinder with two key-ways is apparent. The pins serve as bolts and hold the rotating key plug, or key plug and master ring, firmly in place until the insertion of the proper key raises them to a position which releases the plug. A variation of a thousandth of an inch from correctness will make the key inoperative. The number of pins and the number of possible points of separation on each pin make the number of key changes practically unlimited and give a great degree of security. The shell is a bronze casting, into which the other parts are fitted. In use, the body of the cylinder is concealed, the only visible portion being the end or face, the mechanism being only approachable from the front. The lever or trip at the end of the key plug is varied to suit the nature of the work to be done, the line of Corbin door locks embracing every function and type required by modern conditions. Fig. 95 49 HARDWARE OF SPECIAL DESIGNS Fig. 96 The Corbin designers make a specialty of artistic interpretation of architects’ sketches. They are familiar with the treatment of the detail of ornament in the different periods of art and faithfully reproduce the characteristics of each.
