BURGLAR-PROOF SAFE.

Application filed February 25, 1913.

To all whom it may concern:

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

This invention relates to burglar-proof safes and vaults and, more particularly, to the peculiar structure thereof in which the locking-bolts are not affected when a high powerexplosive is discharged in the door- .jamb crevice where safe-blowers usually work to get at the interior of the safe.

The main object of the invention is to provide a safe, which, when locked, is secure against malicious opening thereof by means of high explosives, there being ample means provided in its construction for the outward escape of the force of said explosives, which means will readily take the shock and duly relieve the high-pressure thereof by giving way under less pressure or force than that required to break or release the locking-bolts.

A further object is to so construct the door as to protect the locking-bolts as much as possible by placing them out of alinement with the customary exposed door-jamb crevice. This feature is accomplished bv providing a round door that has on its outer face lateral wings or plates that extend in opposite directions and with one of such extensions pivotally-connected to the fore-wall' of the safe for hinging said door thereto.

In the accompanying sheet of drawings, Figure 1 is a horizontal cross-section taken through the front portion of a safe that is constructed according to my invention herein; Fig. 2, a front elevation of the safe; and Fig. 3, a rear elevation of the improved round safe-door and its lateral-extensions. 1 represents the safe-body having in its fore'wall a circular man-hole, and 2 the middle or body portion of the closing-door. The body 2 has an inner circulanportion that forms the door'proper and is somewhat tapered to engage the correspondingly tapered and stepped jamb of the man-hole. Said body 2 has an integral laterally-extended portion 5 at opposite sides thereof that considerably overlap said circular-portion and greatly beyond the man-hole, ap-

proaching the side edges of the fore-wall, as shown in both Figs. 1 and 2.' It is in these lateral-extensions 5 that I prefe'ably provide a number of horizontal, tapered openings or outwardly-expanding vent-passages that are weakly filled or plugged with a soft or fragile material 6 such as lead, plaster, wax, or the like. These tapered o enings preferablycommunicate with a common recess or countersink 7, as shown in Figs. 1- and 3, on the inner faces of both of the lateral-extensions 5. Each of the countersinl-zs 7 forms a common communicating-chamber at each. vertical side of the door 3, in the said lateral-extensions 5 thereof, for the said tapered openings or vent-passages and allows for a uniform distribution of any explosives that may possibly be surreptitiously inserted or forced beneath the said lateralextensions 5, and thereby distributes the high pressure or heavy shock of the explosion to all of the said weakly filled or plugged openings or ventpassages. If desired, however, each side-chamber 7 may be further filled with an absorbent material plosive and thereby somewhat further weaken or reduce its exploding force, or altogether destroy its fracturing, rupturing, or bursting power.

The locking-bolts 8 are provided in the inner circular-portion 3, that formsthe door proper, in a suitable manner and are duly connected to a time-lock mechanism 9. Besides, I prefer to mount a permutation or combination clay-lock device 10 on the outer laterally-extending portion 5 (to the left) of the front of the door, and it has suitable bolts 10', as shown dotted in Fig. 2, and, also, in plan in Fig. 1. The clay-lock 1O materially adds to the resisting-strength of the safe and renders it somewhat difficult to open the door, especially in the said lateral left-extension 5 thereof.

In operation, the entire door structure is swung outwardly from closed position and vice versa on the forked arm 11 that is hinged at 12 to the safe-body and it is, also, pivotally-connected at 13 to the outer face of the middle or body portion 2.

It is obvious that the door, constructed as herein shown, will prove an invaluable one in the art of safe building, it rendering the safe quite secure. against surreptitious vnipulating opening by the use of high explosives in the covered and hidden door-jamb thereof. In the event an explosive is placed beneath the lateral left-extension 5 adjacent the daylock 10, or near the hinges 12, beneath the lateral right-extension 5, Where it would be most often and likely applied, it Would immediately expand or spread into the common chamber 7 adjacent the said day-lock, or the said hinges, respectively, or both,

where it would be widely distributed or dissipated throughout the said chambers 7 along either or both of the lateral-extensions 5 of the door Within their overlapping surfaces. Upon the ignition of the explosive the Weak or fragile fillings or plugs 6 in the tapered openings or vent-passages will instantly give way and escape outwardly before the locking-bolts-S can possibly be affected or break and-thus render the use of any explosives offpractically no avail in breaking into-.the 'afeafidr'istructed as herein, due mainly,- ,.t'o-j the impossibility of confining the'said explosives in the air-tight chambers 7 beneath the laterally-extending portions 5 of the door.

The fact that the inner circular or round portion 8 of the door proper, wherein the main locking-bolts 8 are located, is entirely concealed and protected by means of the laterally-extended portions 5, makes it quite plain that the safe is rendered still more effective and secure against surreptitious bursting or destruction by the ignition of explosives therein.

The customary eccentric 14: and its malever or handle 15 are mounted on the hanger of the door so that the center of the latter may be duly placed under the pressure of the said eccentric when the door structure is closed.

Copies of this patent may be obtained for I claim 1. The combination of a hollow safe-body having a circular man-hole in its fore-Wall a circular closing-door forthe said manhole and extending outwardly beyond the face of said fore-Wall, and opposite lateralextensions on the said outwardly-extending part of the circular door adapted to lat-,

orally-overlap the said man-hole adjacent the point of co-action of the circular door and its circular man-hole.

2. A burglar-proof safe comprising a hollow body-portion having a circular manhole a circular closing-door for the manhole, oppositely-disposed lateral-extensions on the outer face of said circular door each having an expanding-chamber beneath it and overlapping said man-hole, horizontal vent outlets or passages providedin the said lateral-extensions and leading from said expanding-chambers to their outer faces, fragile or easily dislodged plugs'inserted in said vent outlets or passages and adapted to receive and offset the high pressure of an explosive when fired within said lateral-extensions.

3. A safe comprising a body-portion havinga suitable man-hole, a door adapted to properly engage said man-hole and having oppositely-disposed lateral-extensions, and horizontal vent outlets or passages provided in said oppositely-disposed lateralcxtensions and expanding outwardly from the inner face of said extensions to the outer face thereof and forming a ready escape for any explosive fired beneath the said lateralextensions.
