Abstract
A device for stopping the striking of a time-striking clock at night which includes a striking stop contact driven by a clock gear train through the agency of an associated intermittent gear train. The intermittent movement of the striking stop contact is controlled in connection with the preselected times at which the strikings are to be made, so that the stopping and resumption of the striking may be selected not to fall on the preselected times, thus assuring a reliable operation of stopping the striking at a desired time.
