SPECIFICATION formingpart of Letters Patent No. 295,272, dated March 18, 1884.

Application filed October 30,1833. (No model.)

To @255 whom it may concern.-

Be it known that 1, Max MosLER, a citizen of the United States, residing at Cincinnati,

county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Fire-ProofSafes, of. which the following is a specification.

The object of my invention is afire-proofsafe which will afford absolute protection in case of fire, and yet be lighter to handle and cheaper to construct than the ordinary tire-proof safe. Its object is also to protectthe contents from dampness or in} ury from the moisture of the fireproof filling when closed for a long time.

With these objects in view, my invention consists in entirely inclosing the inside of the safe when closed by an air-chamber, which is entirely out off from the exterior air when the safe is closed, but has free communication with the external air when the safe-door is open.

It consists, also, in certain peculiar arrangements of the inside of the door and bolt-work, all of which will be fully described in connection with the accompanying drawings,and then particularly pointed out in the claims.

Figure 1 is a central vertical section of my improved safe, taken from front to rear of the safe, and looking to the hinge side the door is shown open and in inside plan view, with part of the inside covering-pl ate removed to expose the bolt-work and means of fastening the plate. Fig. 2 is a horizontal transverse view taken centrally through the closed safe. Fig. 3' is an inside plan view of the form of door and bolt-work I use in constructing double-door safes. In this view the back plate is removed. Figs. 4 and 5 are details showing the manner of locking the back plate to the inner side of the door.

The exterior or frame-work A of the safe is constructed in the usual manner, as is also the door-frame B, except the inner flange through which the bolts pass. The bolt-holes in this inner flange pass entirely through, to comma nicate with the air-chamber O, which entirely surrounds the body of the inside box. D. This box is secured on the inside flange of the doorframe in the usual manner, and the air-chamher 0 is formed by a larger box, E, which is secured upon one of the intermediate flanges of the door-frame B.

The bolts F F, instead of being solid, as customarily employed, are tubular, to open communication between the chamber in theinside of the door and the chamber O,surrounding the recep tacleDnvhen the dooris closed. The bolts F, Fig. l, are for this purpose open at theirinner ends, while the bolts F are longitudinally slotted at f for the same purpose. The space between the box E and the outer walls of the safe is filled with a nonconducting fire-proof material. The inner flange of the door in the single-door safe, Fig. l, is beveled off at the pass the bolts F,which radiate from the center of the door. The angles ofthe frame B are also beveled to correspond with the bevel on the innor flange of the door. The beveled corners of the frame are perforated to receive the bolts, which thus communicate with the air-chamber 0 when the safe is closed. The bolts are shot out from the centerof the door and retracted by a slotted cam-disk, G, acting upon pins which project from the coupling-pieces f into the slots. The cam G is secured upon the bolt-arbor which passes through the door, and is provided with the usual handle or knob upon the outside. The coupling-pieoefisaringslipped over the end of the tubular bolt F and held to it by a setscrew and an arm projecting from one sideof the ring, and having an outwardlyturned end or pin to enter the eccentric slot in the cam-disk G. I prefer to use this separate upon the bolt for the purpose of regulating its throw; but the end of the tubular bolt could be cut away to leave an arm or spur upon the innor end, in which the pin which enters the eccentric slot in disk G could be secured, and thus dispense with the coupling f. The bolts F are guided radially,when the disk G is turned,by the perforations in the flange of the door and door, which forms the inner wall of the airchamber in the door,which chamber also contains the lock and bolt-work of the safe. The inner plate, H,(shown broken awayin Fig. 1,) is preferably hinged to the flange on the hinge edge of the door. To the inside of the plate H I secure one or more Z-shaped angle-pieces, h which, when the cam G is turned to protrude the bolts,as seen in Fig. 1, will lock the door or plate H against opening. The purpose of this arrangement is to prevent any one from in corners, and the beveled portion perforated toguide -lu gs f secured upon thelock-plate ofthecouplingpiece because it admits ofadjustment specting the lock not shown) which dogs the bolt-worl ,and learningits combination. \Vhen the bolts are retracteoLthe cam G, in retracting them,passes from over the inwardly-prey ecting arm of the piece h, and the door H may then be opened, so that when it is desired to leave the safe-door open for some time it is only necessary to throw the bolt-work as when the safe is locked, and by turning the lock-arbor disarrange the combination of the tumblers. Thus the door H can only be opened by those knowing the combination ofthe lock. The same result will be accomplished in the door having the common form of bolt-work as seen in Fig. 3 by having the button or lug h on the front edge of the inside plate or door to pass between the edge of the inside flange and the bolt-bar f so that the bolt-bar will engage its hooked end when the bolts are thrown out.

For the purpose of allowing the button to pass inward, the bolt bar is notched, as shown, which notch should be a little larger than the inwardly-projecting end of the fastening piece or button I is in width.

It is obvious that the button h or a similar device secured upon the inside of the plate H could be engaged by pins or spurs upon the bolts, so as to be protected against opening by the combination-lock. I therefore do not limit myself to the exact devices shown.

I'prefer to make my safe with a removable bottom plate,so that the outerchamberbetween the walls of the safe and box E may be filled from the bottom with fire-proof material; but it may also be filled from the back, as safes are now usually filled.

I am aware that it is not new to arrange the solid bolts of a safe-door radially, so that they may be projected simultaneously from the corncrs of the door by means of devices located at the center thereof; and I am also aware that it is not new to bevel the corners of the door and door-frame of a safe, and I wish it understood that I do not cl aim either ot'these features per se.

\Vhat I claim as new, and desire to secure by Letters Patent, is

l. The combination, in a fireproof safe, of air-chamber G, surrounding the inner receptacle, D, and the safe-door, having an inner airchamber, which is also the receptacle for the bolt-work, with tubular bolts to communicate with the chamber 0 and the chamber in the door when the safe is closed.

2. The combination, in a fire-proof safe, of the safe-body A and stepped door and door frame with the inner receptacle, D. secured upon the inner flange or step of the door-frame, and the box E upon one of its intermediate steps-0r flanges, so as to form two chambers within the safe-body, the outer one for the reception of a tire-proof filling,and the inner one bci ngan air-chamber,substantiall y asspecitied.

3. The combination, with a safe having an air-chamber, and a door-frame the corners of the inner step of which are beveled and perforated opposite said air-space. of the door provided with an air-chamber, and havingits inner step similarly beveled and perforated, the tubular bolts radiating from the center of the door, and adapted to be projected through the beveled corners ofthe door and door-frame, and means for simultaneously projecting and retracting the bolts.

4. The combinatiomwith the safe-door having a chamber, and the bolt-work arranged within said chamber,ofthe inner door or plate, constructed to close said chamber,and provided with lugs adapted to be engaged b y the boltwork when the bolts are shot.
