Abstract

PURPOSE:To make forward and reverse rotation of an alarm wheel and a hour- hand wheel possible by separating a cam of performing falling action from a constant speed wheel and forming the cam as one body with an alarm cam body so as to make the cam project. CONSTITUTION:A cam 8 to carry out falling action is separated from a hour- hand wheel 5 and is formed in an alarm cam body 7 as one body. The alarm cam body 7 fits on the hour-hand wheel coaxially and slidably in the axial direction. Associated rotation of the hour-hand wheel 5 and the alarm cam body 7 is assured by the mating of the cam 8 with a hole 9. At the time set for alarming, the cam 8 falls into a recess 10 of the alarm wheel 2, and the alarm cam body 7 falls and it is displaced to close an alarm switch. If the alarm wheel 2 is rotated to right in order to correct the set time of the alarm, the inclined face 8b of the cam 8 slides along the inclined face 9b of the hole 9 and the cam 8 moves upwards. The cam 8 thereby can get out of the recess 10.
