BURG,LAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 391,041, dated October 16, 1888.

Application filed May 23, 1888. Serial No. 274,800. (No model.)

To all whom it may concern:

Be it known that I, llIAX 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 a more secure safe ata less cost of production; and it consists, mainly, in dispensing with the multiplicity ofjoints necessary in the construction of the safes now in common use and the labor and expense of drilling and bolting the parts together, and in avoiding the weakening of the walls by openings passing through the exterior plates of the walls and doors.

The invention will be first fully 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 indicated by similar reference-letters wherever they occur throughout the various views, Figure 1 is a side elevation of my improved safe when made of the circular form. Fig. 2 is a horizontal central longitudinal section of the same, taken through line :0 0c of Fig. l, the door-operating device upon one end being omitted, as it is a mere duplicate of the one shown upon the opposite end. Fig. 3 is a face elevation of the door and its hinge. Fig. 4 is a horizontal longitudinal section of my invention adapted to a square or angular bodied safe on line a: w of Fig. 5. Fig. 5 is a front elevation of the same. Fig. 6 is a side elevation of the same upon a reduced scale, showing the opened door in inside elevation.

Referring first to the form illustrated in Figs. 1 to 3, inclusive, the body A of the safe is composed of five cylindrical tubes fitted and secured together in any approved manner, the outer, inner, and central tubes, a a a, being preferably of soft iron, and the intermediate tubes, 12 I), being of laminated steel and iron, or of tempered steel alone. In the form shown the inner tube, a", is divided in the center for the purpose of receiving the partition 0, against which the inner ends of the divided tube abut and hold it in place. The ends B of the body, which constitute the doors, are formed of four shells, three of which, 0 c c",

are preferably of soft metal and one laminated or steel shell, (Z, and one steel or laminated disk, (1', between the outer shell, 0, and adjacent shell 0. The inner cylinder, c of the body projects out at each end beyond the cylinder a outside of it, and is exteriorly screwthreaded to receive the interiorlyscrewthreaded rim or flange of the inner shell, 0*, of the door. The laminated or steel cylinders b 1) project out beyond the soft center shell, a, forming an annular groove to receive the projecting flange or rim of steel shell (I of the door, and the steel cylinder 1) projects out beyond the inner cylinder, 1). The purpose of this arrangement is to break the joints, so as to prevent drilling or forcing explosives into the interior of the safe, the doors virtually forming heads for the cylinder, meeting in tongueaud-groovejoints,thetonguessnuglyfittingthe grooves when the door is screwed into place.

The safe is mounted upon a platform, D, which is provided with casters D. The safe is supported above the platform in standards D the upper parts of which are made to conform to the shape of the safe, whichjs secured in place by bolts 6, passing through the upper ends of the standards and into the outer cylinder, a. The standards are secured to the platform by bolts 6, passing through their feet and into or through the platform D. Upon each end of the drill-proof shell b are toothed rings E,which are fitted to revolve and slide upon said shell. The rings are revolved by pinions F, which are mounted upon shafts f, which have their bearings in the top of standards F, and are provided at their ends with crankle vers F for revolving the shaft and pinions. The rings E have plain portions E, upon which are secured hinge-plates c, the opposite members of the hinges being secured to the exterior shells, c, of the doors. Now it will be seen that the doors are screwed onto or off from the ends of the safe-body by revolving the shafts f, and through them the pinions F and rings E E, and that so soon as the screws upon shells a and c are disengaged the doors may be swung back upon their hinges. In order to prevent the door from swinging open after the screws are disengaged before the hinge-pintles reach vertical positions, catches care provided to hold them closed. There are also provided boltsf, fitted to slide upon ICO top of the standards F and enter perforations in the side of pinions F to lock the rings E E, so as to hold the doors in a horizontal plane when swung open. The cross-bar or handle B, Fig. 3, secured to the front of the door, is for the purpose of ahand-hold for conveniently swinging the door open after itsscrew-threads are released, and for swinging it back and into engagement with the screw upon the cylinder a when it is desired to force the door to the position shown in Figs. 1 and 2 by means of gear E F. I have so far described a double safe constructed in accordancewith my invention-that is, one having a central dividingpartition, 0; but it is of course obvious that a single safe may be constructed upon the same principle by any one skilled in the art of safemaking from the above description. I contemplate the use of time-lock mechanisms to lock the body and doors rigidly together for predetermined times in substantially the same manner as now is common in circular doorsafes. No specific description of these mechanisms is necessary, as they are well known.

' It is sufficient to say that the locking mechanism controlled by the time mechanism may be applied either to the body or door to connect with the opposite member, whether body or door securely hold the parts together until the dogging device (not shown) is released by the time-lock in the usual manner.

In the form of safe represented in Figs. 4 to 6, inclusive, the construction is substantially the same as the form above described, the principal difference being that this form is square or angular, while the former is circular. The body of the safe and its door come together with tongue-and-groovejoints, as in the former case, and the door is hinged to a sliding band extending around the outer drill-proof shell; but it is evident that in this case the door and its supporting-frame must be made to move out from the body of the safe without revolving, as the frame or band E can simply slide forward and back. The soft-metal shells or parts in Fig. 4 are, as in Fig. 2, indicated by section lines, while the drill-proof plates or parts are, as in Fig. 2, stippled, each being indicated by the same referenceletters, except the inner shells of the door. The shells or flanged plates of the door B are centrally perforated, the opening in the outer hardened shell, i, being larger than the openings in the inner hardened shell, 13, and the intermediate softer shell, j, while the opening through the outer shell, 0, is smaller than either, thus forming an annular groove for the hardened disk 70, which is of a size to freely revolve within this groove. To the outside of this disk is firmly secured a smaller disk, k, of wrought metal, and to this diskis secured the cog-wheel L. Inside of the door end of the inner shell, (6, is a plate, m, which has a central tubular extension, m, which extends through a central opening in the end of the inner shell, a.

.-This tubular extension is externallyscrewthreaded to engage an interiorly screwthreaded cap, it, which is firmly secured to the disk k. The plate m is securely bolted to the shell a 7 O is a pinion secured upon a crank-shaft, which has its bearings in the shell 0. This shaft has a crank-arm, O, by which the pinion and its shaft are revolved to revolve the wheel L, disks 7c 70, and cap a to force the door 13 and its frame or carrier E back and forth, and its screw cap a into or out of engagement with the screw-threaded tube m, so that the door may be tightly closed, as seen in Fig. 4, or disengaged from the said tube m and swung around upon its supporting-frame or carrier,

as seen in Fig. 6.

The mechanism for retracting. and closing the door which I have shown and described is the simplest and most effective known to me for the purpose; but after an examination of what I have herein disclosed other well-known appliances for accomplishing the same result will occur to a mechanic skilled in safe-making. I shall therefore consider all'mere mechanical variations for accomplishing the same result substantially within the spirit and scope of my invention, and in smallsafes the screw-' threaded connections of the body and door may be engaged and disengaged by hand. For this purpose the bar 13, Fig. 3, will be found convenient. It should also be understood that the number and character of the several plates or shells, or the method of securing them together to form the body of my structure, is no part of my invention.

What I do claim as new, and desire to secure by Letters Patent, is-

1. The combination of the safe-body and its door having interlocking or matched meeting ioints,engaging screws upon the body and door for drawing the body and door together or separating them, and the sliding door-carrier fitted to move upon the body, and hinge for connecting the said door and carrier, substantially as described.

2. The combination, substantially as hereinbefore set forth, of the safe-body and door having interlocking meeting edges, the doorcarrier adapted to slide upon the body and united to the door by hinge'connection, the screw-threaded connection for moving the door out or in from the body, and mechanism, such as described, for imparting motion to one of the screw-threaded parts,whereby the door is carried to its seat or disconnected therefrom.

3. The combination of the safe-body A, having the projecting screw-threaded tube of, the door B, having the interiorly-screw-threaded cap 0, the cogged ring E, mounted to revolve and slide upon the body, the pinion F, meshing with the teeth of said ring, and the shaft upon which said pinion is secured, and the crank for imparting motion to the shaft, substantially as and for the purpose set forth.

4. The combination of the safe body A, formed of alternate plates or shells of soft and the door B, and binge for connecting the door and ring, the screw-threaded connections of body and door, the pinion, its shaft and I5 crank for revolving the door, and its supporting-ring, and the sliding bolt for locking said pinion, ring, and door, substantially as and for the purpose set forth.
