Abstract

973,814. Spring storing mechanisms. B. & R. RELAYS Ltd. Dec. 14, 1962 [Dec. 14, 1961], No. 44790/61. Heading F2S. [Also in Division H2] A driven shaft 3 of an electrical control device (see Division H2) has a spiral return spring 16 attached at one end to a disc 17 which is restrained from rotation with the shaft by a tooth 34 engaging a spring catch 19. A cam 18 rotating clockwise with shaft 3 releases the catch 19 when the spring has reached a certain tension, and the spring then rotates the disc 17 to the next catch 19<SP>1</SP>. Thus the spring 16 never exceeds a certain tension while the shaft 3 continuously rotates. When rotation ceases the spring 16 returns the cam 18 and the shaft 3 to a predetermined position, viz. with a tooth 33 of the cam engaging one of the catches 19, 19<SP>1</SP>.
