Abstract

10,087. Pelli, P. Sept. 9, 1912, [Convention date]. Burglar and like alarms.-Electric contact devices C, shown in detail in Fig. 1, are fixed on the sides and top, and devices D, Fig. 3, on the doors of a money safe, the apparatus being connected as shown in Fig. 11. The battery A is in circuit with a hand switch F, bell B, and bus-bars G, the terminals on the bus-bars being so arranged in two insulated sets that the contacts C, E are all connected in parallel. The devices C each comprise a metal frame h pivoted on a removable spindle i and adjusted in unstable equilibrium by means of a screw k, so that on being shaken the frame h falls and closes the alarm circuit through the springs l. The device D shown in detail in Fig. 3 comprises a projecting piece m mounted on one door of the safe, and a conducting-plate p, and leaf spring o on the other door, the parts p, o being held out of contact by the projection m so long as the doors are shut but serving to close the circuit as soon as the doors are opened. This part of the circuit may be broken by hand by means of the sliding switch q.
