766,112. Watches. HEIMANN, P. March 29, 1955 [May 24, 1954], No. 9113/55. Class 139. In a watch the regulator is controlled by the hand-setting means. In the groove of the clutch wheel 3, Fig. 1, is a split ring 9, Fig. 2, which has a projection 10 which engages a slot in a link 12, Fig. 1, connected to a lever 13 pivoted to the setting lever 6. The lever 13 has a limited longitudinal and translatory movement and is forked to form two pawls 16, 17 which co-operate respectively with ratchets 18, 19 on a spindle 20 which carries a pinion 26, Fig. 4, which meshes with a rack 27 on the regulator 28. The arrangement is such that when the winding stem 1 is moved to its hand-setting position the lever 13 is moved downwardly. On rotation of the stem 1 the ring 9 rocks the lever 13 through the link 12 to bring the appropriate pawl 16, 17 into engagement with its ratchet 18, 19. If the rotational pressure on the stem 1 is maintained and the stem returned to the winding position the said ratchet 18 or 19 is stepped-on and the regulator 28, moved through the pinion 26 and rack 27. An indicator 30 is attached to the lever 13.
