Abstract
468,358. Electric switches. V. G. MANUFACTURING CO., Ltd., and GELDEREN, F. M. VAN. Dec. 2, 1935, No. 33355. [Class 38 (v)] [Also in Group XXXVIII] A device for opening the circuit of an electric motor driving a gramophone and for ensuring an interval of time before the circuit is again closed comprises a cam 6 on the mechanism 5 which returns the sound reproducer arm to starting position, a dashpot being adapted to be operated by the cam 6 to open the circuit, and after a given time to close the circuit again. As shown, the cam 6 depresses the dashpot plunger, a pin 9 on which then bears on a limb 11 of a trip device 10, 11 pivoted at 13 with the switch ; and this rocks the switch to open the circuit. After a given time, the pin 9, in rising again, bears on the limb 10 and rocks the switch back to the closed position. A friction spring is provided to brake the movements of the switch.
