Abstract

707,755. Clocks. GAZDA, A. July 13, 1951 [July 26, 1950], No. 16646/51. Class. 139. A self-winding clock for a vehicle comprises a casing, a mainspring for the time mechanism, a ratchet wheel, a train of gears connecting said ratchet wheel with said mainspring, a member pivotally mounted at approximately its centre at the centre of the casing, a weight at one end of said member, the other end of said member being of sector shape and having an arc shaped recess therein, the opposed arcuate edges of said recess having a common centre of curvature in the pivot point of the pivotally mounted member and pivoted pawls fixed to said member at said opposed arcuate edges of said recess to actuate said ratchet wheel to wind said mainspring upon oscillation of said member due to said weight in either direction. The mainspring 5, Fig. 1, is connected through a train of gears 6 to a ratchet wheel 7 disposed in arc-shaped slot 15 in a pendulum member 17 pivoted at 16 and carrying a weight 18. A pair of pawls 9 and 10 carried by the member 17 are spring-urged into engagement with the ratchet wheel 7 so that when the pendulum oscillates in either direction one of the pawls steps on the ratchet wheel. The clock is in a casing 26 positioned in the hub 28, Fig. 3, of the steering wheel below a magnifying lens 29.
