Claim:
A striking mechanism unit for a repeater striking mechanism, said striking mechanism unit comprising a drive plate with a pipe pivotally mounted about a pivot axis, said drive plate carrying a click including a hook with a beak returned towards said pivot axis by a spring, said click being able to move against said spring by the action of a pin comprised in a detent ratchet, said detent ratchet being comprised in said striking mechanism unit and being arranged to cooperate with a main strike control mechanism, and said striking mechanism unit including a pipe ratchet arranged to be pivotally mounted on a said pipe about said axis and to cooperate, in a toothing comprised therein, with a beak, said beak, depending on the position thereof, allowing or preventing the pivoting of said pipe ratchet, said pipe ratchet being mounted to pivot integrally about said axis with a first hour ratchet arranged to cooperate with a first lifting piece for driving a hammer comprised in said repeater striking mechanism in order to release a first sound transmission called a main strike, said striking mechanism unit including a release wheel for the release of another sound transmission including an alarm mechanism and called a secondary strike, said secondary strike being different than the main strike, said release wheel and said detent ratchet being independent of each other and each controlled by different control means selected to actuate, respectively said secondary strike or said main strike, wherein said release wheel and said detent ratchet are both arranged to cooperate, but never at the same time, on said hook to allow the transmission of energy to a sound mechanism to play, respectively, said secondary or alarm strike or said main strike.
