SPECIFICATION forming part of Letters Patent No. 498,457, datediMay 30, 1893. Application tiled June 16, 1892. Serial No. 437,002. (No model.)

To @ZZ whom it may concern.-

Be it known that we, JOHN L. BUCKINGHAM and CHARLES S. MoORoRY, citizens of the United States, residing at Hermosa, in the county of Custer, State of South Dakota, have invented certain new and useful Improvements in a Combi-ned Hasp and Lock, of which the following is a specication, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in combined hasps and locks, and it has for its objects among others to provide a simple and cheap lock and hasp in which the lock is so connected with the hasp plate that it can be turned down or up to allow the door to be held closed when unlocked in the ordinary way, with a pin passed through the staple passed through the slot in the hasp plate, and when it is desired to lock the door the lock can be turned so that the staple will enter the slot therein and the door be looked. The lock is also of novel construction. It is provided with a back plate having a projection or lug to engage a stop on the hasp plate to bring the lock to astop at the proper point to insure the registering of the slots in the hasp plate, and back plate of the lock. We provide two plates within the lock to confine the spring which actuates the bolt and serve also as guides for the bolt; one

of these plates serves the further function ofY a combination plate by the slight alteration of which dierent combination keys may be employed. l

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claim.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specication and in which- Figure 1 is a perspective view showing our improved hasp and lock in position. Fig. 2 is a rear view of the lock with the rear plate removed. Fig. 3 is a view of the rear plate detached. Fig. 4 is a section through the lock and hasp plate on the line 4 4 of Fig. 2.

Like letters of reference indicate like partsl throughout the several views.

Referring now to the details of the drawings by letter, A designates the case of the lock which may be of any desired shape and which may be made as ornamental as desired. Itis made practically hollow and is provided with a key-hole a and substantially central passage a. in which the bolt works. The sides of this passage are formed by the plates B which are held in position in any suitable manner, and one of which is provided with a slot or opening b for the passage of the fin of the key as seen best in Fig. 4. This plate is made detachable and by slightly altering the shape of its slot or opening it may be readily fitted for dierent forms of keys. At one end of the case there is a chamber or recess A at right angles to the bolt as seen in Figs. 2 and 4, which is adapted toI receive the staple on the door and into which the end of the bolt is thrown by the spring C which is arranged behind its other end in the central passage a as seen in Fig. 2. The boltD is loosely guided between the plates B and'is normally thrown outward to enter the staple by the spring C. Its outer end is rounded as seen at CZ to permit ready passage thereover of the staple in entering, and its rear face is formed with a shoulder CZ as seen in Fig. 4 to receive behind it and hold the staple as indicated by dotted lines in said Fig. 4. Upon itsface adjacent to the key-hole the bolt is formed with a notch cl2 having a curved wall d3 and a shoulderd4 as seen best in Fig. 2 which is designed to be engaged by the n of the key in actuating the bolt. The plane described by the fin of the key isindicated by dotted lines in Fig. 2.

E is the back plate of the lock. It is designed to be detachabiy held in position to the back of the case in any suitable manner as by screws passed through the holes e provided therefor. This back plate is provided with a slot E which, when the plate is in position, cornes coincident with the recess or chamberA of the case as shown best in Fig. 4. It is further provided with a lug or ear E2 with a hole e2 to receive a rivet, pin or other means F by which it is pivotally held to a hasp plate G as seen in Fig. l, which hasp plate may be of any desired length and width and has one portion Gr hinged to the part carrying the lock as by a common hinge g as shown in Fig. 1. The hasp plate is provided with an elongated slot g which when the parts are in position to be locked comes coincident With the slot in the back plate and the recess or chamber A of the case as seen in Fig. 4. The back plate is further formed or provided With a projection or lug Gr2 which is designed to engage a stop or pin ll on the hasp plate as seen in Fig. l to bring the parts in their proper position so all the slots Will register.

y lt will of course be evident that alock constructed as above described may be permanently affixed to the hasp plate instead of being pivotally affixed thereto, but it is preferred to pivot it for reasons hereinbefore given.

Modifications in detail may be resorted to Without departing from the spirit of the invention or sacrificing any of its advantages.

'What We claim as nevi7 is- The combined hasp and lock herein described, the same comprising a hasp plate with a hingedy portion, the movable portionV being provided with a stop or pin near its free end and a lock case having a back plate with apertured lug above its longitudinal center and pivotally held to the movable portion of the hasp and a diametrically opposite prog ection or lug to engage said stop to limit the movement of the lock case and bring it 1n proper position, said back plate having slot coincident With a slot in the movable portion of the hasp and with a recess in the lock case, substantially as specified.

In testimony whereof we aftix our signatures in presence of two Witnesses.
