Abstract

1276957 Time switches LANDIS & GYR AG 3 Aug 1970 [8 Aug 1969] 37336/70 Heading H1N Each time an adjustable tappet carried by a timing disc (not shown) passes a star wheel (not shown) carried on a shaft 3, the shaft 3 is rotated through a predetermined angle to wind up a spring 9 but before the spring is fully wound it is released by a mechanism actuated before the shaft has rotated through the predetermined angle. The spring 9 is secured to a shaft 6 and to a rotor 7. Shaft 6 is coupled to shaft 3 by gearing 4, 5. As shaft 6 rotates from the position shown a stop 13 carried by a plate 14 is moved out of co-operating engagement with an outer radial projection 12 of rotor 7 to permit spring 9 to rapidly rotate the rotor until it is arrested when an inner radial projection thereof co-operates with stop 13. Plate 14 and stop 13 are reciprocated by a cam 15 carried by the shaft 6 which co-operates with a pair of rotary discs 16, 17 on the plate 14. Rotor 7 co-operates with a contact spring cam follower 19.
