` PERMUTATION-LOCK.

Specification of Letters Patent.

Patented July 22, 1919.

Application filed January 13, 1919. Serial No. 270,895.

To all whom t may concern:

Be it known that I, MARK KosrcH, a subject of the Government of Montenegro, residing at Washington in the District of Columbla, have invented certain new and useful Improvements in Permutation-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its principal object to provide a comparatively slmple and inexpensive permutation or combination lock which will be particularly well adapted for use upon safes and vaults, although it is, of course, also ap licable for other purposes.

A further o ject is to provide a lock in which a sliding handle is provided for operating the bolt or bolts, and in which the locking of such bolt or bolts is accomplished by lookin of said handle through the instrumenta ity of permutation means housed therein.

With the foregoing in view, the invention resides in the novel features of construction and novel association of parts to be hereinafter fully described and claimed, reference being made to the accompanying drawing which forms a part of this ap lication.

Figure l is an elevation of a oor equipped with the invention.

Fig. 2 is a horizontal section of the lock with parts in elevation, showing the relation of parts when the bolts are extended. y

Fig. 3 is approximately a duplicate of Fig. 2 but discloses the relation of parts when the bolts are retracted.

Fig. 4 is a vertical section the line 4 4 of Fig. 3.

Fig. 5 is an elevation of the permutation lock means, the handle being broken awayT and in section to illustrate such means.

Fig. 6 is a transverse section on the plane designated by the line 6-6 of Fig. 4.

Fig. 7 is an end elevation of one of the tumblers.

Fi 8 is a detail section the line 8 8 of Fig. 7

Fig. 9 is a perspective view of one of the indicating rings with which the tumblers are equipped for properly positioning them to release the lock.

Briefly speaking, the lock consists of a hollow sliding handle H mounted on a door D or .other suitable Support. one or more on the plane of on the plane of' bolts B carried by the door, connecting means C between the handle and bolts for operating the latter from the former, lock means L for holding the handle against shifting, and adjusting means A whereb the combination may be varied as require The door or the like D is here shown as provided with four of the bolts B and the inner side of said door is formed with channels 1 in which said bolts are mounted, a plate 2 being secured over said channels by screws or the like 3. The several channels 1 open at their inner ends into a recess 4 formed in the door D, said recess leading to the exterior of said door and being by pref @rence of greater diameter at its inner end than at its outer end. The` handle H extends at its inner end into the recess 4 and the connecting means C between said handle and the bolts B, are located in said recess, said connecting means being herein shown in the form of one piece links extendin diagonally from the handle tothe bjo ts, 1n such manner as to project said bolts when the handle is forced inwardly and to retract them when an outward pull is exerted on said handle.

For supporting the handle H, a post 5 is ixedly mounted on the door D and extends outwardly from the recess 4, the inner end of said post being equipped with a cylindrical head 6 which is rotatable in an opening 7 in the door, this rotary mounting being provided in order that the post 5 may be turned to change the combination of the lock in a manner to be described. To normally hold the post 5 against rotation, a pivoted arm 8 and La toothed ring 9 are provided. The arm 8 is pivoted at 10 to a plate 11 secured on the lnner end of the post 5, while the toothed ring 9 surrounds the inner end of thepost and is secured by screws or the like 12 to the inner side of the door. The arm 8 is adapted to engage any of the teeth of the ring 9 and it will thus be seen that dill'erent rotary adjustments of the post 5 may be made. To retain the arm 8 1n engagement with the ring 9, a keeper 13 is provided, said keeper being shown in the form of a dished plate receiving the ring 9, the arm 8, and the plate 11, screws or the like 14 bein employed for detachably securing said eeper to the door so that it may be removed whenever required to change the combination of the lock.

The Ahandle H is formed of an inner setq tion l5 and an outer section 16 which is hollow throughout the greater part of its length. The section 15 is provided with a bore 17 through which the post 5 extends and the outer cud of said section 15 is rcinovably received in the inner end of the hollow outer section 16, a screw or thc like 18 being provided for connecting the two sections. iVhen the handle is forced inwardly to project the bolts, the screw 18 is inaccessible, but when the handle is withdrawn as in Fig. 4, the screw in question may be removed to permit disassembling of the lock.

As one means of connecting the links C to the handle H, a collar 19 has been shown surrounding the inner handle section 15 and clamped between a shoulder 2O on said section and the inner end of the outer scction 16. It will be understood that other means could be provided for connecting the inner ends of the links C to the handle H.

The post 5 eXtendsthrougl-i the hollow portion of the outer handle section 16 and is provided on its outer end with a removable head 21 slidin in the bore 22 in the solid outer end or ob 23 of said handle section, the portion of the post in the hollow part of the handle being rovided with spaced lateral projections 2 suitably located.

Rotary tumblers 25 are mounted in the hollow handle section 16 and are by preference carried within a sleeve 26 which is secured by a screw or the like 27 to the outer end of the handle section l5, said sleeve having internal rings 28 which space the tumblers apart and hold them against shifting longitudinally of the handle. Each tumbler is provided with an opening through which the post 5 passes and with a groove 29 which may travel over the adjacent projection 24, when the several grooves are alined with their respective projections, thus permitting the handle H to move outward f and retract the bolts B. When the handle is forced inwardly and the tumblers 25 rotated to move the grooves and projections out of alinement, the handle is locked against movement on the post 5 and consequently the lock cannot be released.

To render the tumblers 25 accessible for operation, one side of the sleeve 26 is cutaway as shown at 30, this cut-away portion registering with a similar slot 31 in the handle section 16, and if desired, an apertured plate 32 may be secured over the slot 31 as seen in Figs. 4 and 6, the openings of said late and the slot in question being of su cient size to allow the fore-finger to be inserted for the purpose of turning the tumblers.

In order that the tumblers may ,be roperly positioned, indicating rings 35p 'are mounted thereon, und these rings are provided with projections 3l, receivable in any one of a number ol' sockets. 35 with which the tumblers are jnovidiul. When the lock is disassembled, one or more of the projections 34: may be witlulrawn Afrom its socket and disposed in another Iand by this means, it will be seen that a different churacter must appear at the opening of the plate 32, in order to properly sct the tuinblers YFor releasing the lock.

From the foregoing, taken in connection with the accompanying drawings, it will be seen that I have provided a pern'iutation lock of rather simple and inexpensive nature, yet one which will be highly efficient and in every way desirable, the device being particularly well adapted for use upon safes and vaults. Since probably the best results are obtained from the details disclosed, they may well be followed, but within the scope of the invention as claimed, considerable latitude is allowed for making numerous changes in minor details. Furthermore, it is to be understood that the lock is applicable for numerous purposes and is not, therefore, restricted to use upon safes and the like.

What I claim is:

1. The combination with a closure and a bolt carried thereby; of a hollow handle eX- tending from said closure and bodily slidable inwardly and outwardly, means actuated by the sliding action of said hollow handle for operating said bolt, and means in said handle for locking the latter against sliding.

2. he combination with a closure and a bolt carried thereby; of a hollow handle extending from said closure and bodily slidable inwardly and outwardly, means actuated by the sliding action of said hollow handle for operating said bolt, and permutation means in said handle for locking the latter against sliding.
