MEANS FOEVAULT PROTECTION.
Specification of Letters Patent.
Patented May 19, 1914.
Application tiled March 27, 1912. Serial No. 686,679.
T0 all @cham t may concern Be 1t known that I, WILLIAM D. Hain- MOND, a citizen of the United States, resid- Angeles and State of California, have invented new and useful Means Jfor Vault Protection, of `which the -following is a specification. l
This invention relates to means for preventing burglars or unauthorized prrties from obtaining access to banks, storage or other vaults by breaking through the walls of such vaults, and the main object of the invention is to provide electrical protecting devices for the vaults associated with the vault structure in such manner that the Walls of the vault cannot be cut into or damaged without aii'ecting the electrical circuit, and on the other hand the walls of the vault protect the electrical circuit from being tampered with. l
Other objects of the invention will appear hereinafter.
The accompanying drawings illustrate an embodiment oi the invention, and referring thereto:
Figure l is a perspective of a vault partly broken aivay.' Fig. Q is a diaphragm of one form of electric circuits `suitable tor use in connection with the invention, said circuits providing for open-circuit and closed-cir cuit protection, and also visual signals by 3 is adiagrain showing an electric circuitv'herein the signal lamps are energized by current through the protective cable. Fig. el is a transverse section of the protective cable. Fig. 5 is a detail perspective, of a portion ot' the cable with the cement removed, showing the interlinking ot the loops of the cable.
Referring to Fig. 1, the Iwall. or casing oi" a bank or storage vault is indicated at 1, said Wall consisting, tor example, oi cement, conciiete or other suitable material, preferably such as to constitute an electrical insulator for the 'embedded protective cable. The protective cable 2 embedded or molded in this concrete or cement wall, being and .forth within said Wall, pre'lei'ablyin both longitudinal and transverse directions, or vertical or horizontal directions, as the case may be, so that it isnot possible tor any part of the Wall to be broken or cut Without exposing some part of the conductor.
The cable 2 may consist of a metallic cov# in the county of Los ering or armor 3, and Wires 4, 5 and v6 inclosed Within said armor and insulated from one another and from the armor by suitable insulation 7.
The invention is used preferably in connection i'vith a triple protective circuit, such as shown in Fig'. 2, Where 10 designates the battery for the closed circuit connected by lWires 11v and 1Q through electro-magnetic indicators or galvanometers l and 14 'with the respective ends oi the Wire ot the cable 2, a rheos-tat 1,5 beingincluded in this circuit so as to regulate the current through the indicators. rEhe open circuit battery 17 is connected by wire 18 to one end of the cable Wire f1, the opposite end of the other wire 6 being connected by a wire 19 through a. relay Q0 to the other side of the battery 17. One of the open circuit. wires may be connected by connection 3lto theA armor 3 of the' cable. Said relay controls suitable signal devices, for example, a visual signal consisting of electric lamps 22 and Q23 which are connected in circuits 2l and Q5 'leading from the battery 2G respectively to the back and vfront. contacts Q7 and 28 oit the relay Q0. A return connection 30 leads from the armature 3l of the relay to the battery so that, When the armature is` on bar-lv: contact eircuit is' closed through lamp which may be a blue lamp, Whereas when the relay armature is on the iront contact circuit is closed tlnough lamp 23, which may be a red lamp. 4
The cable above described is set in position in the space in which the Wall of the vault is molded, so that it `1 s. :nies embedded in the cement or concrete walls, the said Walls servingY to support and protect the cable, and the cable ,giving` indication of penetration or fracture oit' the walls by reason oit' the etl'ect oi such penetration or tracture on the electric connections constituted by the cable. Thus, it the wire 5 is broken at any point by pinion-ation ci". the cable, the indicators 13 and 14- iu the closed circuits 11 and 12 'will show the fact of such opening 0i the circuits, or if the circuit 5 is grounded at any portion such grounding will be shown by reading ot the indicators 13 and 141. l'f a metallic tool penetratesl the cable in such manner as to establish connection between the Wires 4i ra d 6, the relay Q0 will operate to shiit the signal lamps from the blue lamp to the ,red lamp connection andthe same eiect occurs if the Wire 6 is grounded with lli the armor, 3 of the cable, said armor being connected to the other Wire of 'the open circuit by connection instead oit' controlling the lamp signals by a relay in an open circuitthrough the cable, the supply current for the blue or safety lamp may pass through the cable itself, as indicated in Fig. 3, the blue lamp 22 being in this case included inthe circuit 4 which passes 1through the cable and in series connection with a relay 20 Whose back contact 32 controls the circuit for the red lamp 23. The battery 26 in this case is connected in the circuit in series with the relay 2G and blue lamp 22 so as to cause said blue lamp to be illuminated as longas thecable Wire 4 remains unbroken. n rupture of the ca le Wire 4f,
the relaw allows the armature 3l thereof in 5, thus binding the to close Contact at 32 for the circuit of red lainp 23 which thereupon becomes illuminated by current from battery 26, the supply of current to the lamp 22 being cut oli by the rupture of the circuit therethrough.
The loops of the cable, passing in differ`- ent directions may be' interlinlred, is-shown Wall portion of the cable to the ceiling portion, so that neither can be'bent Without disturbing the other. i
What I claim is: i l. The combination of a- Vault having a cementitious Wall, a iiexible metal-armored cable'embedded and molded into said wall and bent in a plurality of loops so as to completely surround the interior of the vault, Y every 'portionl of the Wall including looped portions of the cable extending transversely to one another, some of the loops of the cable being interlinked with other loops arranged transversely thereto to bind the angular ,portions of the vault together, an insulating .conductor Within said cable, and a signal ing of the conductor with the cable armor lwhen the' armor is indented or penetrated by a tool will cause the operation of the signal.
3. A Vault protecting system comprising a oementitious inclosing Wall, a ileXible metalarmored cable embedded in said Wall and bent back and forth in loops so as to surf round the interior ofthe vault, said cable comprising a plurality of conductors insulated from each other and from the armor, a controlling` circuit having connection With said conductors and including a signal, said conductors being arranged to be fcrced'together When said armor is indented or penetrated by a tool to thereby complete said circuit and effect operation o the signal.
In testimony whereof, I have hereunto set my hand at Los Angeles, California this 19th day of March, 1912.
W. D. HAMMOND.
In presence of- ARTHUR P. KNIGHT, F. A. CRANDALL.
