Abstract
897,813. Electric clocks. HAMILTON WATCH CO. Jan. 22, 1960 [Jan. 22, 1959], No. 2470/60. Class 139. In an electric clock having an electromagnetically maintained balance carrying a coil the switch which is periodically closed to energize the coil comprises a metallic coating of the balance impulse pin 15 and the escape wheel 17 driven thereby. A permanent magnet 19 completes each movement of the escape wheel 17 the arbor of which is connected by a small permanent magnet 31 and a conductor 26 to the pole 24 of the battery 25 the other pole 28 of which is connected by a member 29 to the frame plate 30.
