Abstract

533,186. Electric selectors. GENERAL ELECTRIC CO. Ltd., and ROSE, W. R. Oct. 16, 1939, No. 27945. [Class 40 (iv)] In a switch of the vertical and rotary type normally released by forward rotary stepping, vertical release is effected by a separate magnet which withdraws the vertical pawl and detent, and also restores a portion of the vertical offnormal springs. When the switch moves off-normal, cam plate 8 engages cam 9 on pivoted member 34 carrying an operating arm 35 for one portion 7 of the vertical offnormal springs and cam plate 28 operates arm 27 of another portion 6 in a manner not shown. The armature 15 of the vertical release magnet 14 is spring mounted at 16 and engages a rocker arm 21 which is adjustable by means of an eccentric at 22 and has bent portions 24, 25 operating on the pawl 10 of the vertical magnet (not shown) and the detent 11. The armature 15 also operates a bell-crank 17 engaging an arm 26 carried by the operating arm 27 of the off-normal springs 6.
