PRIOTECTING -o Ev |c|-: "FOR BA'NK-SAFES.
SPEGIFICATION forming part of Letters Patent No. 286,566, dated October 9, 1883.
Application filed July 14,1833. .(Xo model.)
cinnati, in the county of Hamilton and State of Ohio, have invented certainnew and useful Improvements inProtecting Dev ices forBa-nk- Safes, 850., of which the following is a specia each has electrical communication with a separate electromagnetic signal of any suitable or customary construction. One of these circuits (which is closed when set) operates an alarm by having its continuity broken. The
other circuit (which .is open when set) operates an alarm by having its continuity restored. Such association of two distinct circuits working in diverse fashion constitutes a double safeguard that operates with various manifestations to indicate whatever clandestine attempt is made at disturbance of the guarded object, and which advertises the very characterof the disturbance. I 1
In the accompanying drawings, Figure 1 is a partly-sectional diagrammatic representation of an apparatus embodying my invention, the same being shown in its set condition. Fig. 2 represents the circuit-changing mechanism in its discharged condition. Fig. 3 is a transverse section at the line a: x. Fig. 4 represents the device adapted for use in connection with more than one object. Fig. 5 shows the form used when the circuit-changer is at right angles to the movement of the protecting object.
A is a non-metallic tube, sheath, or housing, which is made fast to the safe body or casing, so as to present it at right angles and in near proximity to the door Bor other protecting object.
Attached interiorly to the tube A is a rod,
U, of brass or other metal, to whose rear end piece G.
oped by a sleeve, E, of Vulcanite or other insulating substance, a spring, F, attached to which holds a metallic rod, 0, similar to the rod C. Said rod 0 is held by said spring F is attached a wire, D. This rod (3 is envel- 5o normally out of contact with said rod 0. At- 5 5 tached to the front end of rod 0 is a nonmetallic push piece or button, G. proceeds a wire, I). The rods 0 C constitute the terminals of an electromagnetic circuit From the rod 0 containing one or more voltaic batteries, (see broken lines in Fig. 1,) whoserupture (by the separation of said rods 0 C) operates to sound an alarm, Y, with which the wires D D communicatc. Embracing the sleeve E and made fast to it is a metallic band, H, to which is attached a wire, J. Also embracing said sleeve, but capable of sliding freely along it, is a similar band, H, which has rigid but insulated connection K. with the rod O through the push wire, J. The bands H H constitute the terminals of an electromagnetic circuit, whose closure (by the contact of said bands) operates to sound an alarm, Z, with which the wires J J communicate. J are wrapped with insulating material, and all (for compactness, and tomake it difficult to tamper with them) are, wherever exposed to view, preferably twisted into cable form, asshown in Fig. 1. p
The above-described duplex circuit-changer is so located upon the safe or other receptacle to be protected that closure of the .door B operates to bring into juxtaposition the oppos- Proceeding from the band H is a All the four wires D D J ing ends of the rods G O, and to thus, for the The act of opening the door to the person in charge the special nature of the intrusion. Should the trespasscr, on the other hand, resort to the expedient of cutting the wires, he will only the more distinctly give i circuit) will make communication between them, and will give information (by sounding the alarm Z only) of thecexact nature of the disturbance. It is thus manifest that several different kinds of intrusion are not only equally sure to communicate information of disturbance, but to particularize in what that disturbance consists.
For use with two or more protecting objects-such, for example, as a safe-door and a money-drawer, B, (see Figs. 4 and 5)the terminal mechanism above described is repeated at the additional object. device the circuit which is closed when set is connected in series, as follows: The wire'D of the circuit C D Y D G communicating with the rear rod, 0, of one pair ofterminals, the opposing rod, 0, of the same pair communicates,

1. In an electromagnetic safe-protecting device, the two pairs of terminals 0 O and H H, having separate electrical connectionwith as many signal circuits or systems, adapted to act simultaneously-the one by opening and the other by closureby movement of the safedoor or other protecting object, substantially as set forth.
2. In an electromagnetic safe-protector, the combination, with as many distinct alarms of the dupleX' terminal mechanism of which one part consists of normally-separated rods 0 O, that constitute the terminals of one, alarm system, and that, when set, form part of a closed circuit that operates to sound the alarm on being opened, and of which the other part consists of normallyclosed bands H H, that embrace rod 0, (from which they are insulated,) which bands constitute the terminals of the other alarm system, and, when set, form part of an open circuit that operatesto sound the alarm on being closed, substantially as set forth.
3. In an electromagnetic safe-protector, the duplux circuit opener and closer, consisting of the fixed terminals 0 and H, the shifting terminals 0 and H, insulating-sleeve E, spring F, non-metallic push-piece G, and the rigid connection K, the whole being inclosed in a non-metallic attachment sheath or housing, A, substantially as set forth. 7
