Abstract

1401140 Gearing for synchronous clocks SEIKO KOKI KK 11 April 1973 [13 April 1972] 17350/73 Heading G3T [Also in Division F2] Reduction gearing for a clock comprises a continuously driven ratchet wheel 23 whose teeth 22 are engaged by two driving pawls 16, 17 frictionally mounted on eccentric parts 12, 13 carried by a rotary driving member 10. The eccentric parts are 180 degrees out of phase and the member 10 is a gear driven by a pinion 27 on motor shaft 28. The pawls are frictionally mounted by means of their split ends 14, 15 but other mounting arrangements are described using axial pressure, Fig. 4 (not shown) or resiliently formed eccentric parts, Fig. 3 (not shown). The drive is stated to be quiet and the parts may be of plastics.
