Abstract
1,084,555. Time switches. ENGEL & GIBBS Ltd. Nov. 12, 1965 [March 1, 1965], No. 8722/65. Heading H2B. [Also in Division F2] An electrically-operated timing device comprising a synchronous motor 10 driving an output shaft 11 through a reduction gear-box 12 and a synchronous drive and reserve clock mechanism 13 is characterized by the escapement (77), (Fig. 6, not shown), of the reserve drive clockwork mechanism 36 being at all times freely operable by the spring of the clockwork mechanism and running slightly " slow " so that the final drive shaft 11 is responsive only to the motor drive via synchronous drive portion 30 when the motor is in operation. Both drives 30, 36 have one-way ratchet clutches 32, 42, and manual operation of the clockwock mechanism 36 is permitted by including a spring winding ratchet 44 in the input drive assembly as part of the winder gear 37 on shaft 39. Clutch 42 (see also Fig. 4, not shown) engages only when the motor 10 stops and drives shaft 11 from a barrel 38 connected by gears 40, 41, with the usual escapement (77). The timing device controls electric switches as described in Specifications 1,084,554 (Fig. 1, not shown), 1,079,522 and 1,036,568.
