1,232,156. Clocks and watches. PARECHOC S. A. Aug.8, 1969[Aug.9, 1968], No. 39688/69. Heading G3T. A regulator assembly for a timepiece comprises a screw 12 arranged tangentially of the assembly and adjustable in a threaded line in the studholder 1 to rotate regulator parts 8, 9 and curb pins 10 carried thereby, a tongue 8a on the part 8 urged by its resilience towards the base of a groove 11 in the screw 12 having frusto conical side walls converging to the base which has a width less than the width of the tongue 8a. The latter thus engages both side walls of the grove 11 so that there is no lost motion when the screw 12 is turned to adjust the regulator. |
