AUXILIABIY DOOR FOR SAFES.
Speccaton of Letters Eatent.
Fatented Dec. 141, 1915.
Application led July 13, 1915. Serial No. 39,590.
To all `whom it may conce/m Be it known that l, HARRY C. Firm, a citizen of the United States, and a resident of Toledo, in the county ot Lucas and State oi' Ubin, have invented a new and improved Auxiliary Door for Safes, oi which the following is a full, clear, and exact description.
An object ot' my invention is to provide a door element or auxiliary door in connec-` tion with the ordinary door or doors of satte, so arranged as to prevent the sate trein l'zeing blown open with nitro-glycerin, or other explosives.
A further object of the invention is to utilize the explosive torce exerted against the said door element for releasing a third drill-proof door element and jamming the same into a tapered seat on `the door jainb.
ln carrying out my invention, use is made oit a dished door formed of yielding inaterial and separably supported on an outer door, so that the two present opposed snrfaces for receiving the force of an explosion,
c' whereby the explosion will cause the separation oi' the said doors. The force of the eX- plosion will cause the dished auxiliary door or door element to expand and interlock into a groove provided in the door j amb to receive it. At the same time, the inner built-up drill-proof door will be released and forced into a tapered portion of the safe-opening; or door j amb.
rlhe invention will be particiilffirly eX- plained in the specific description following. v
Reference is had to the accompanying drawings forming part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which:
Figure 1 is a vertical section of a safe door and portion of the safe embodying my invention; Fig. 2 is a vertical section on the line 2-2 Fig. 1; and Fig. 3 is a fragmentary View on a smaller`scale similar to Fig. 1, showing the manner in which an eXplosive material will be received by my improved door.
In carrying ont my invention, an eX- terior door 10 is provided, here shown conventionally, and of simple Jform, it being understood that the form may be varied. A second door or door element 11 is provided forming the inside of the safe door, and an intermediate door or door element 12 is provided. i
The door element 12 is of dished forni and is supported in place by the said inner or outer door, preferably by the outer door 10, as shown, there being a frame 13 extending around the dished door 12 and secured to the latter by any suitable means, such as rivets or studs 1st.. rlhe element 12 is of yielding materiah' while the frame 13 is preferably of cast material. Said .trame 13 is received in the door 10 at the inner face, there being preferably a flange 15 on the frame' 13 engaging the surrounding member 10a of the door 10. A filling 10b is conventionally shown in Fig. 1 in the door 10. rl`he'arrangement is such that the door or door element 12 will be supported with sufficient stability to move with the door 10, but will be subject to ready separation there- :troni under the force of an explosion. Between the doors 12 and 10 is an intervening space or pocket 16 which is tapering, owing to the dished formation of the element 12.
ln 4blowing open a safe door, the cra cksman usually inserts a row of sinallwedges along the top of the door, wedging it open suiliciently that when a small dam A (Fig. 3) of putty, soap, or the like, is formed on the door at the opening thus provided, nitroglycerin may be poured into the dam to enter said opening` andvpenetrate between the safe door and the iainb thereof. There then remains only the setting oli of a detonator B placed on top of the sateto explode the nitro-glycerin. With my invention it will be seen that the nitro-glycerin will be received in the pocket or annular space 16, and upon being exploded, the force of the explosion will be exerted on the door element 12 and the door 10. The explosion detachee or fractures the frame 13 and the increasing expansion will force the element 12 into a groove 17 in the jamb 18 of the safe 19.
A further result of the explosion will be to jam the door or door element 11 at the inner side tightly in the tapered seat 18a which is provided on the jamb 18. The element 11 is laminated and drill-proof, and if it is attempted to drill and blow off the door element 12 by a second explosion, the opposed surfaces of said element 12 and the door element 11 will receive the force of the explosion and the door 11 will be more tightly wedged into its seat. The door element l2, it will be seen, contacts adjacent to its edge with the edge portion of the inner drill-proof door 1l, so that the resistance oiiered by the door ll will cause the expansion of the element 12 into its groove 17, the pressure resulting at the same time in the amining of the door ll as described.
' I would state in conclusion that although the illustrated example constitutes a practical embodiment of my invention in very simple form, I do not limit myself strictly to the mechanical details shown, since manifestly the same can be considerably varied without departing from the spirit of the invention.
Having thus described my invention, what I claim as new and desire to secure by Lettei's Patent, is:
l. A safe door including a main exterior door'and a dished door separabiy supported on the main door at the inner face thereof and adapted to lock with a sate under the flattening tendency of an explosive charge against said dished door, said doors present ing opposed surfaces to receive the force of an explosion to cause a separation of the doors. y
2. The combination with a salie, of an outer door, an inner door, and a supplemental intermediate vdoor normally released from the safe, and means wherebv said supplemental door is adapted to be forced into a permanently locked position with the safe by the force of an explosion and forming in the locked position a means preventing access to the said inner door.
3. A safe door including an inner door elenient, an outer door element, and an interme` diate door element together with means for vsupporting the said elements for effecting a Velosureof the safe, the outer and intermediate door elements forming an intervening space to receive an explosive material and presenting opposed surfaces to receive the torce of an explosion to cause a separation between the outer element and the intermediate element and force the intermediate element against the inner element, said inner, outer, and intermediate elements being each in the form of a closure to extend over the door opening of a. safe.
4. A dooi element comprising an outer door and an inner dished door element presenting its concaved side outward, and a frame extending around said dished door and to which the latter is secured, said traine being detacliably received by the said outer door.
5. A closure for safes including an extorior door, an inner door, means to support said doors on a sate, an intermediate door. means to support said intermediate door in released relation to a sate and means wherebv, the said intermediate door is adapted to be forced by an explosion into position having locked engagement with the safe, the intermediate door in its locked position forming a mea-ns preventing access to the inner door.
6. A safe door including a main door and a Second door, having means to separably support the same with respect to the niain door at the inner face of the latter and means whereby said second door i.' adapted to be forced into locked engagement with a safe under the force of an explosion, said doors presenting opposed surfaces to receive the torce of an explosion to cause separation of the doors.
In testimony whereof I have subscribed my name to this speciiication in the presence of two subscribing witnesses.
