Abstract

PURPOSE:To reduce the loss of the gear trains of a clock to be caused by the charge, by mounting an escape pawl to the control lever which opens and closes the contact point of the time striking structure and arranging so that the load of the control lever do not transmitted directly to the time cam wheel. CONSTITUTION:When the time cam wheel revolves to push up the contact board 22a to the arrowed direction, the end part of the contact board 22a touches the escape pawl 60 which is supported by the control lever 50. At this time when the contact board 22a is pushed further upward by the time cam wheel revolution, as the escape pawl 60 is supported by the contact board 22a, only the escape spring 64 connected to the escape pawl 60 is charged to the contact board 22a. By arranging so that the change of the escape spring 64 is considerably smaller than that of the charged spring, the charge loss to the time cam wheel by the contact board 22a becomes considerably smaller. Therefore no undersirable effects are given to the clock gear trains.
