BURGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 380,717, dated April 10, 18:88.

Application filed December 23, 1887. Serial No. 258,784. (No model.)

To all wiz/0m, it may concern.-

Be it known that I, MAX S. GoLDsMiTH, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Burglar-Proof Safes, of which the following is a specification.

My invention relates to burglar-proof safes. Its object is an improved mechanism for automatically locking the safe by closing the door and automatically releasing the locking mechanlsm by opening it, the said mechanism be* ing under the control of a time mechanism,so that no opening is required through the door.

The invention will be first described in connection with the accompanying drawings, and then particularly referred to and pointed out in the claims.

Referring to the drawings, in which like parts are represented by similar reference-let ters wherever they occur throughout the varions views, Figure l is a front elevation of my improved safe. Fig. 2 is an inside elevation of the door and front wall of the safe,the parts being locked. Fig. 3 is a vertical section taken through line x a: of Fig. 2. Fig. 4 is an inside elevation of the door and front wall with the lookingabutments removed and the door attachments shown in the position they assume when released by the time-lock. Fig.,5 is a transverse section through line y y, Fig. 2.

The body of the safe and door may be of any approved construction.

My improvements are attached to the in side of the door and the frame surroundingit, and these only will be described.

To the inside of the door A is secured a surrounding frame, B, which has an outwardlyprojecting flange, b, and upon the inside of the safefront,near the edges of the door-opening,are journaled the cam-abutments O,which, when the door is,closed,are, by the act of clos ing the door, turned so that their flat surfaces firmly press against the flanges b and prevent the door from being opened so long as they are locked in the position shown in Figs. 2,3, and 5. These abutments are secured upon shafts c, which shafts have their bearings in boxes c', which are firmly secured upon the door-jambs D. Upon the ends of the shafts c are secured beveled gear-wheels C', which, meshing with each other, secure the shafts and their abutments together.

Upon the opening edge of the door, against the wall of the frame B, is secured a toothed rack, B', the flange b being cut away to receive it. This rack, when the door is being closed, engages the teeth of a cog-Wheel, C, which is secured upon one of the abutmentshafts c, and by partially rotating said lshafts force the cam projections of the abutments C against the flange b.

It is evident that so long as the shafts c and abutments are free to turn, the door may be readily opened and closed, and that when the door is closed and the abutments locked against turning, the door will be securely locked.

The means by which the rotating bolts or abutments are automatically locked by the act of closing the door will now be described.

E is a latch-bar fitted to slide in boxes e, which are secured upon the inside ofthe door. Its upper end is hooked to engage a hooked eatch,f, which catch is controlled bly a timelock, F. The lower end of the bar E is beveled,so that it will slide over a pivoted tappet, G, when the door is closed, and force the bar up until its upper hooked end catches upon the time-lock hook f.

H H are bolt-bars jointed to the bar E by a pin, e,which passes through slots in the adjacent ends of the bars H, the two bars H forming a togglelever having fulerums on pins h h, which pass through slots in the bars and are secured in the door.

h h are coiled springs having their ends sccured, respectively, to the frame B and the bars H. el e2 are similar springs, the ends of which are secured, respectively, to the bar E, and pins secured in the door. these springs is exerted to pull the bar E down when released, and withdraw the ends of the boltbars H from between the abutments and door-jambs, so as to leave the abutments free to turn as the door is opened. rlhe springs h pull bars H under the abutments when their ends have passed the door-frame. The frame B is slotted to allowthe bars H H to pass through. The lower end of the barI E drops back of the tappet G, and as the door is opened The tension of 9o IOC thetappet is turned upon its pivot until the latch-bar passes it, after which it is returned to its position, as seen clearly in Fig. 3, by the coiled spring g. When the time-lock is set-,its latch f is in a vertical position, as seen in Fig. 2. Now, when the door is closed, the tappet G will force the bar E up into engagement with thelatchf. The springh' will at the same time force the ends of the bars H H between the flattened parts of the abutments C and the front Wall of the safe, securely locking the door, as seen in Figs. 2, 3, and 5, until a predetermined time at which the time movement is set to throw its hookf back, as seen in Fig. 4, and release the bar E.

One of the shaft-bearings c is notched or cut away upon one edge, as seen at the upper right-hand corner of Fig. 2, and a pin, c, projects from the edge ofthe abutment C into this notch, for the purpose of limiting the movement of the abutments when the door is opened and stopping the cog C2 in proper position to engage the rack B when the door is again closed. The handle or pull J is secured inthe outer plate of the door, and by the arrangement above described no opening through the door is necessary. The tappet G is stopped in the proper position to receive the impact of the bolt-bar E by a bar, g', Which is secured across the opening or recess in the edge of the door which is made to receive the tappet.

I do not limit myself to the exact arrangement of devices, as it is evident that structural changes may be made without departing from the spirit or scope of my invention, the essential features of which are the recessed dooredge, the journaled abutments upon the jamb, an actuating device upon the door to automatically turn said abutments into the recess when the door is closed, and locking-bolts controlled by a time mechanism to lock the abutments until released by the time movement.

What I claim is- 1. The combination, substantially as hereinbefore set forth, of the door having upon its inner face laterally-projecting anges, abutments journaled in bearings secured upon the jamb and geared together, a rack upon the door-edge and gear upon the abutment to engage together and automatically turn the abutments against the flanges as the door is closed, a bolt-work to lock the abutments, and a time mechanism to control the bolt-work.

2. The combination, substantially as specified, of the door having inwardly-projecting flanged 'frame B b, rack B', time-movement Ff, and the spring bolt-work controlled by said time mechanism, with the doorframe having journaled abutments C c, engaging gears C, and cog C2, for the purpose set forth.

3. The combination of the door-frame, the abutments C, journaled in bearings secured thereon and surrounding the door-opening,

the beveled gears C', gearing said abutments' together, the cog C2, secured upon one of said abutments, with the door A, provided with the frame B, having flange b, and rack B', to

engage the cog C2, the bolt-bar E, beveled at the lower end and hooked at the upper end to engage the releasing-hook of the time mechanism, the bolt-bars H, linked to the bar E, the springs h and e2, to pull the bar down when released, the tappet G, to throw up the bar E when the door is closed, and the time mechanism Ff, constructed as and for the purpose set forth.
