Abstract

969,933. Clocks and watches. ETA A.G. EBAUCHES-FABRIK. April 17, 1962 [April 21, 1961], No. 14844/62. Heading G3T. In a timepiece, a detent 13, Fig. 1, has, besides the usual holding faces 5, 6, a locking face 10 which engages the side of an adjacent tooth 8 of the step-by-step driven gear 1 and prevents reverse rotation of the gear e.g. the date ring of a calendar watch. The locking face may be adjacent the face 6 if the gear is driven in the other direction.
