Abstract
388,491. Reciprocating motors. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, PUCKETTE, C. C. and ERIKSEN, J., c/o General Electric Co., Stoke, Coventry. Nov. 10, 1931, No. 31126. [Class 35.] In a self-interrupting telephone selector, smooth stepping is facilitated by an inertia disc 13 frictionally coupled to the ratchet wheel 6 and held in position in the interior of the wheel by a spring 16 or by screws fitted with springy washers and passing through slots in the disc. The interrupter springs 7 are adjustable by means of a screw 8 passing through spring 15 and bearing against the frame 14.
