CIRCULAR DOOR FOR SAFES.

SPECIFICATION forming part of Letters Patent No. 590,943, dated September 28, 1897. Application filed June 1, 1897. Serial No. 838,876. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM COREY, a citi zen 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 Circular Doors for Burglar-Proof Safes, of which the following is a specification.

My invention relates to that class of burglar-proof safes provided with a circular door which is opened and closed by screw-threaded connection between theinner face of the door and its jamb and held in the closed position under guard of a time-lock.

The object of the invention is to provide means to securely hold the different plates of a door together without perforating the outer plate.

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

In the drawings, Figure 1 is a transverse sectional view of the front of a safe embodying my invention. The door is shown in hori-' zontal diametrical section on the right and partly in elevation and partly in radial diagonal section on the left of the vertical center, the-section being taken through lines as x of Fig. 2. Fig. 2 is a front elevation.

The door in both views is shown in the closed position.

The safe-body A, the support B, secured to the outside of the door, its handle I), and the crane-hinge C, in which the support is pivoted, are of ordinary construction and so well known that they need not be specifically described.

Theouter plate of the door D is centrally recessed, the recess extending about half-way through the plate, leaving an annular flange (1 extending around its inner edge. The inner wall of this flange is tapped to receive the circular exteriorly-screw-threaded disk or plate E, which is about the same thickness as the plate D. One half of the plate E is embedded in the plate D, and the other half projects to enter the interiorly-rabbeted ring F, which is screwed onto the disk or plate E. The inner opening in the ring F is tapped to receive the exteriorly-screwihreaded disk G,

which is screwed down against the plate or disk E. The rabbeted and screw-threaded ring H is screwed tightly against the inner face of the ring F. The ring H is screwthreaded. exteriorly to engage the screwthreads at in the inner reduced opening of the jamb, whereby the door is closed by turning it in one direction and opened to disengage the ring II from the jamb when turned in the opposite direction in the usual way.

The parts D, E, F, and G may be either of roll-tempered or laminated steel and of any number and thickness desired. The engaging collar H is preferably of cast steel.

In constructing myimproved door, the parts being formed as shown in Fig. 1 and the plate D tapped and screw-threaded-in proper place to receive the bolt f, the ring F also perforated and countersunk on the inner face to receive the shank and head of said bolt, and the disk G being also bored and tapped to receive the screw-bolts g, and the inwardlyprojecting flange of the ring or collar H being perforated and countersunk to pass the shank and embed the heads of said screws r, the disk or plate E is first screwed tightly into-the plate D and the ring F then turned around until its inwardly-projecting flange and its abutting face fit tightly against the inner faces of the plate D and ring E. The bolts f are then inserted to prevent unscrewing the ring. The disk G is then tightly screwed in place in the ring F and against the face of the plate or disk E, the collar I-I screwed tightly down over the said disk G, and the screws g tightened into place, completing the door. It

terior bolts for holding the plates from revolving, but it is evident that keys or other means may be employed instead.

In a round door for safes the combination of the outer plate interiorly recessed and screw-threaded, the inner ra b'beted and interiorly-screw-threaded ringsand the circular nection, and the bolts to prevent the parts plates or disksto lock the said rings and outer from turning, substantially as hereinbefore 10 plate together, substantially as shown and set forth.
