Abstract
673,283. Locking rotary elements. ETERNA, Ltd. WATCH FACTORY. June 13, 1950 [June 23, 1949], No. 14750/50. Class 80 (iv). In a mechanism for preventing reverse rotation of a wheel 1, a pawl 5 pivoted on a fixed axle 4 co-operates with two concentric sets of pins on the wheel. The two sets 2a, 2b ... and 3a, 3b ... are relatively staggered so that on clockwise rotation of the wheel the pawl is oscillated, lugs 6, 7 thereon moving into and out of the gaps between the pins, but on anticlockwise movement of the wheel the pins engage one or other of locking surfaces 6a, 7a and rotation is prevented. An arm 10 may be provided to balance the pawl, and the lugs 6, 7 may be spaced along the pawl by a whole multiple of the division between two pins. In a modification, Fig. 2 (not shown), a pawl provided with spaced lugs oscillates within an annular recess in the face of a wheel and co-operates with non-staggered radial projections formed by stamping apertures in the wheel face.
