JOHN SCHADE, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE HOPKINS dc DICKINSON MANUFACTURING COMPANY, OF SAME PLACE.
LOCK.
SPECIFICATION forming part of Letters Patent No. 421,977, dated February 25, 1890. Application filed January 8, 1389' serial No. 295,771- (ModeL) To all whom it may concern.-
Be it known that I, JOHN SCHADE, a citizen of the United States, residing at the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cylinder Locks, of which the following is a specification, the ac companying illustrative drawings forming a part thereof.
Similar letters and numerals indicate similar parts in the several views.
The ends attained by my improvements will successively appear in the progress of the specification. The cylinderlock consists of two principal partsthe plug and the shell. The plug and itsconcomitants are illustrated in Figures 1, 2, 3, 4., and 5. The shell audits concomitants are illustrated in Figs. 6 and 7. Fig. 1 is a front end view of the plug. Fig. 2 is a plan view of the two forms of the tumblers employed and their driving coiled springs. Fig. 3 is a plan of the key stoppin and its driving coiled spring. Fig. l is a face View of the cap or disk locatedin the front end of the plug. Fig. 5 is a rear end view of the plug with the sliding fence in position to enter its channel. Fig. 6 is a front end view of the shell. Fig. 7 is a rear end view of the shell. Fig. 8 is a plan view of the plug and shell as the plug is about to enter to its place within the shell. Fig. 9 is a plan view of the shell, showing the dovetail locking-slot in its undercut joint and the dovetail slideby which the cylinder-lock is secured in place when combined with a mortise-lock; and Fig. 10 is a view of the inner mechanism of a mortise-lock with the combined cylinderlock secured in place. I
I construct the plug of a single piece of metal.
0 is the ordinary rectangular channel cut through the plug from end to end, within which the five usual tumblers are located and driven backward by thekey and then forward by the coiled springs 1, behind their arms 6, when the key is withdrawn. Three of these tumblers are constructed in the usual form, like T, and two of them in the corresponding form, like T, with notches 3 for enga ing the edge of the rectangular opening 0 in the usual sliding fence 4. at the rearend of the plug.
My first improvement is presented here in the grooves 5, cut on both sides of the arm 6 of the several tumblers at the like point near their angle. The purpose of these grooves will best appear in connection with the description of the cylindrical sockets '7, which I drill in the plug at its front end for receiving the driving coiled springs 1 of the tumblers. Heretofore the functions of these sockets has been performed by what may fittingly be called rectangular stalls opening wide into the rectangular channel C. By substituting these cylindrical sockets, communicating by narrow openings .9 with the rectangular channel C, I furnish both support and protection to the driving coiled springs of the tumblers, while the arms of the tumblers, by meansof the grooves 5 and the corresponding guides in the opposite sides of the narrow openings 5, formed with tongues fitted to enter said grooves, slide up and down in line within the said narrow openings without tipping or tilting laterally. The outside cylindrical portion of the plug is constructed substantially as heretofore. The stop-pin, Fig. 3, with its encircling drivingspring 8 and receiving-socket 9, bored in the front end of the plug, are formed as heretofore. The disk, Fig. l, with its slot 10 for the passage of the key, and its hole 03 for the head of the stop-pin to slide in, and its lugs 11, fit ting into outlets 12, cut in the rim of the counterbored recess R in the front end of the plug, are all constructed substantially as before.
My second improvement appears at the rear end of the plug, where 1 construct integral with the plug the box 13, with a rectangular channel C, equal in area to the channel C, and, in effect, extending the channel C, so as to give stability to the tumblers and prevent them from tilting sidewise, as they are inevita bly inclined to do without such protection as this box affords.
A third improvement appears here, too, in the form of a thin transverse rectangular channel c in the plug, located in front of the box B, for receiving the sliding fence 4... This fence, with its opening C, of equal area with the channel 0, is constructed as heretofore.
The location of this channel 0 in front of the box, as is plainly seen,presents, in connection with the box, an important improvement in the lock.
My fourth improvement appears in the cocentric recess R, formed in the rear end of the shell for operating the sliding fence at. Heretofore this eccentric recess has been constructed in the case of the lock, with which the cylinder-lock has been combined. When so constructed, the use of the cylinder-lock is restricted to combination with the mortiselock; but by constructing the eccentric, as I have done, in the end of the shell the use of the cylinder-lock is extended to combination with any and all other locks. In other respects the shell with its recess at for thehead of the stop-pin is constructed substantially as heretofore.
My fifth improvement appears in the manner of locking the shell to the plug. To do this I cut a groove 13 around the outside of the plug, perpendicular to its axis, just in front of the shoulder 14. I also form two threaded holes 15 in the shell at such opposite points as will bring the groove 13 directly under them when the plug is in place within the shell. Two screws 16, constructed with round ed points and of proper length, now introduced into these holes will lock the shell and plugtogether and still permit the plug to revolve within the shell.
lhe cylinder-lock constructed as now describedmay be secured to the door or to any lock-case in any desired manner, and its dog for operating the bolt of the lock with which it is combined may be attached to the plugin any desired manner. One method, which I here illustrate, is by the use of the dovetail slide 17 which is lowered by the screw-rod 18, attached to the case of the mortiselock, into the dovetail slot 19, formed in the undercut joint 20 at the rear end of the shell. By this means I secure the cylinder-lock to the mortise-lock as firmly asif it were constructedintegral with it. In this exceptional case the dog 21, which operates the bolt of the mortise lock, is formed, as heretofore, upon the rear end of the plug.
Having described my improvements, what I claim as my invention, and desire to secure by Letters Patent, is-= posite sides of the narrow openings between the cylindrical coiled spring-sockets of the plug and the rectangular channel passing lengthwise through it, substantially as and for the purpose hereinbefore described.
3. In a cylinder-lock, the tun1bler-guides fitted to enter the grooves in the opposite sides of the arms of the tumblers, substantially as and for the purpose hereinbefore described.
4. In a cylinder-lock, the combination of the locking-groove around the plug with the lockin g-screws passing through the shell, substantially as hereinbefore described.
5. In a cylinder-lock, the box formed in the plug between the rear end thereof and the thin rectangular channel passing transversely through the plug, in combination with the tumblers formed with grooves in the opposite sides of their arms, and the thin rectangular channel passing transversely through the plug formed in front of said box, and the sliding fence within said channel, substantially as and for the purpose hereinbefore described.
6. In a cylinder-lock, the plugformed with cylindrical coiled spring-sockets in the front end thereof and with tumbler-guides between them, and the parallel rectangular channel passing lengthwise through the plug, the guides fitted to enter the grooves in the opposite sides of the arms of the tumblers, the plug formed also with the box in the rear end thereof and with the thin rectangular channel passing transversely through it in front of said box, in combination with the sliding fence within said thin rectangular channel, the tumblers formed with grooves in the opposite sides of their arms, the locking-groove around the outside of the plug, and the locking-screws passing through the shell, substantially as hereinbefore described;
