Abstract
866,267 Clocks. WEHRLE UHRENFABRIK G. m. b. H. July 25, 1957 [July 25, 1956], No. 23553/57. Class 139 A timepiece having a rack striking work in which a first cam 22, Fig. 3 on the minute hand shaft actuates the lifting piece 1 through an intermediate pivoted lever 28 is characterised in that a cam and lever mechanism is provided for withdrawing the lever 28 from the cam 22 for a predetermined period during a twenty-four hour cycle to render the striking work inoperative. The cam and lever mechanism comprises a cam 44, Fig. 1, rotated one revolution in twenty-four hours and a lever 17 which co-operates with a lever 25, Fig. 3 having an arm 27 which co-operates with the intermediate lever 28. The cam 44 is formed of two relatively adjustable parts so that its drop is adjustable in length and is angularly adjustable by a manually actuable pawl and ratchet mechanism. A pivoted lever 33 may be manually moved -to either side of a centre position to permanently silence the striking or to disable the automatic silencing mechanism.
