ABSTRACT:
A stationary detecting means corresponding to a second time wheel rotating at a higher speed than the hour wheel generates signals at successive intervals of a fixed number of minutes to actuate a time signaling device. A first detecting means is also provided corresponding to the hour wheel. The phase of the first detecting means is set to determine or define an alarm or signaling time. When the phases of the hour wheel and the first detecting means are synchronized, a second signal is generated. The time signaling device is actuated when the time signals of the stationary detecting means and the second detecting means are generated simultaneously.
