Abstract
Striking mechanism unit including a drive plate with a pipe carrying a click with a beak drawn against a return spring by a pin of a detent ratchet cooperating with a main strike control mechanism, and including a ratchet pivoting on this pipe and cooperating via a toothing with this beak to allow or prevent the pivoting of this ratchet, integral with a ratchet driving a repeater striking mechanism to release a grand strike. It includes a release wheel for releasing an alarm, independent of this detent ratchet, each controlled independently to release the play respectively of this alarm or this main striking mechanism, and both arranged to cooperate, but never at the same time, on this hook to play, respectively, this alarm or this main strike.
