PERMUTATION-PADLIOCK.

SPECIFICATION forming part of Letters Patent No. 416,268, dated December 3, 1889.

Serial No. 319,367. (No model.)

, To all whom, it may concern.-

Be it known that I, JOHN KUBLER, a citizen of the United States, residing at Hot Springs, in the county of Garland'and State of Arkansas, have invented certain new and useful Improvements in Permutation-Padlocks, of which the following is a specification.

My invention relates to looks, and has reference more particularly to a lock in which one of the locking-dogs is operated by means of a key and the other adapted to engage with the tumbler or tumblers only after the latter have been brought into proper position by one who understands the combination, the key-operated dog preventing the actuation of the other dog until the former has been disengaged from the hasp of the lock.

In the drawings, Figure l is aperspective view of my improved lock; Fig. 2, a face view of the case or shell with the front plate removed; Fig. 0, an inside face view of the,

front plate andattendant parts removed from the case; Fig. 4, a similar view with the parts in a different position, and Fig. 5 a vertical sectional view.

-A indicates the case or shell of the lock, B

the hasp, and O the dial, the latter being graduated and provided with a knob or handle, as usual.

Secured to the stem or spindle of the dial is a disk or tumbler D, (one or more,) which is provided with a lug to engage a similarlug on a tuinbleror disk E,(one ormore), mounted in the case or shell, the said disks being also provided each with a notch or recess, which come into alignment with each other upon turning the dial-disk in certain predetermined direct-ions and distances, as is usual in permutation-locks.

Pivoted to the front plate F of the lock is a dog G, which carries a lug a, to enter the notches in the tumblers, and a lug or projection I), to engage one of the notched ends of the hasp, the lugs a and I) being so arranged that when the lug a is in engagement with the tumblers the lug b will be out of engagement with the hasp, and vice versa.

Dog or lever G is provided with a nose or extension 0, which extends over toward the upper end of the dog H, which is also pivoted to the plate F, so that in case any one should discover the combination and attemptto open the look by throwing the dog G its nose 0 will strike against the dog H, and thereby prevent its actuation.

I indicates a spring coiled about the pivot of dog G, one arm of the spring engaging a lug on the front plate and the other arm extending upward behind a lug d on the dog, the spring tending to keep the dog in engagement with the hasp.

In order to retract the dog G from engagement with the hasp, I provide a releasing or retracting device J, comprising a rock-shaft f, journaled at its ends in the front and rear plates of the look, a thumb-piece g on the outside of the front plate, and a lug or projection h,'working in a recess t', made in the dog G to receive it. The throw of the lever J is limited by means of a pin or stop j on the front plate, against which the thumbpiece is adapted to strike. Assuming that the dog II has been thrown by the key to the position shown in Fig. 4, it will then be seen that when the tumblers are brought into proper position, with their slots in alignment, and the device J rocked, its lug h, working in'the recess'i of dog vG, throws the upper end of the latter inward toward the tumblers, the lug Ct entering the notches therein, this movement of the dog G being made against the force of the spring I. As the lug to enters the notches in the tumblers the lug b will be withdrawn from one arm of the hasp. Dog H, which is pivoted to plate F, has a lug e to engage the opposite arm of the hasp, and is provided, also, with a coiled spring I, which, like the spring I of dog G, tends to keep its dog H in engagement with the hasp. Secured to the case A is key-post 0, and above the latter a guard 19, which may be of any desired construction, the post being so arranged as to come opposite an opening or key-hole q, formed in the front plate F of the look, as shown. inserted, it can be turned so as to retract the dog H, and as soon as the latter is thrown out of engagement with the hasp it will be found to be in such position as to permit the dog G to be also disengaged from the hasp.

Now, if the proper key be The case or shell A is provided with two ears or lugs 7.: and l,the formerbeing threaded to receive a screw 27?, while the latter is merely drilled out or perforated to receive an extension n, formed upon one arm of the hasp. The front plate I is also provided with ears or lugs k and Z, corresponding with the ears in the case or shell, the ears on the plate being arranged to come into alignment with those in the ease in order that they may receive, respectively, the screw m and extension 11, and thereby firmly secure the front plate and attendant parts in position. The screw m is in line with the opening in the case that receives the arm of the hasp not provided with the extension; hence it is necessary to unlock the lock and release the hasp before access may be had to the screw in, by means of which the front plate is removed. Afterthe haspis released it is raised upward, as indicated in Fig. 2, and as the angular portions of the hasp are out of the opening in the case made to receive them the hasp may be swung or turned upon its extension, so as to permit a screw-driver to be applied to the screw in, and after the screw has been withdrawn from the lug Ir. on the front plate the latter may be removed on withdrawing the extension n from the lug Z, in case that has not already been done.

Ilavingthus described my invention, what I claim is t t 1. In a lock, the combination, with a case or shell, of a series of tumblers, a hasp, a keycontrolled dog adapted to engage the hasp, and a second (log adapted to engage the hasp and also the tumblers, all substantially as shown.

2. In a lock, the combination, with a case or shell, of a series of tumblers, a hasp, adog G, adapted to engage the hasp and the tumblers, and a key-controlled dog ll', arranged in position to prevent the actuation of the dog G, all substantially as shown.

In a lock, the combination, with a case or shell, of a series of tumblers,a hasp, dog G, adapted to engage the tumblers and hasp, a key-controlled dog II, also adapted to engage the hasp, a post 0 and guard 19, secured to the case, and a key-hole q, formed in the front; place.

i. In combination with the case or shell, the tumblers, the notched hasp, the pivoted key-dog II, the dog G, provided with lugs to and h and with a nose 0, and an operatinglever J, serving to actuate the dog G.

5. In combination with the tumblers and the notched hasp, a dog G, provided with lugs a and l), and retracting device J, provided with a thumb-piece j and with a lug 7: to enter a recess t' in the dog G.

(3. In combination with the tumblers, the notched hasp, the pivoted dog II, provided with a spring, pivoted dog G, provided with lugs a b, nose c, and recess 1:, a device J, having thumb-piece g and lug h, and a spring I, hearing at opposite ends against the case or shell and the dog G.

7. In a lock, the combination, with a case or shell A, provided With lugs 7.: and I, (the former threaded, as shown,) of a front plate F, provided with similar lugs 70' l, a screw in, and a hasp B, provided with an extension 12, all substantially as shown.

In witres whereof I hereunto set my hand in the presence of two witnesses.
