Abstract: Stopping mechanism for a striking mechanism comprising energy storage means including a power reserve transmission wheel set, a strike wheel set comprising a detent ratchet, a main click for the passing strike function and/or a repeater release click, the stopping mechanism includes an uncoupling lever for moving the clicks away from the strike wheel set, by an instantaneous jump of a lever changing the position of the uncoupling lever, when the level of energy of the storage means crosses a predefined threshold, through the cooperation between a finger, driven by the power reserve transmission wheel set, and a jumper returned by a first spring, to bring the finger to bear on a fork of the lever to cause it to pivot abruptly by instantaneously changing the position of a lug with respect to a second spring.

Abstract: Timepiece movement with a carillon striking mechanism, striking the hours and quarter-hours with different melodies, the striking mechanism including a quarter surprise-piece coaxial to and superposed on the quarter-snail, in a limited angular travel with respect to the quarter-snail, arranged to ensure the sequential playing of the melodies of the four quarter-hours on the full hour, in the first minute of the new hour, and further including, in the plane of the quarter surprise-piece, a quarter surprise-piece jumper, arranged to drive and/or to lock this quarter surprise-piece.
