Abstract

523,121. Interrupters. GRASEBY, R. C. Dec. 23, 1938, No. 37454. [Class 38 (v)] An oscillating part of an escapement mechanism is connected to one of a pair of contacts to cause intermittent opening and closing of the contacts. In the example, the contacts 14, 15 are on springs 12, 16, the spring 12 having a forked end 10, 11 embracing an ,insulated pin 6 mounted on the pallet lever 3, which in oscillating under the influence of a pin 19 on a balance wheel 4, alternately forces apart and forces into contact the contacts 14, 15, by bending the spring 12. A comparatively stiff arm 18 separates the springs and acts as a stop for the spring 16.
