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:
Moon phase display mechanism including an input pinion which makes three revolutions, or respectively two revolutions, in 24 hours, and drives a 19-tooth or respectively 29-tooth drive pinion, which drives a 59-tooth lower wheel bearing a moon disc with a two-colored depiction including a lighted area and at least one background sky area and also drives a 57-tooth or respectively 58-tooth, upper wheel, coaxial to this lower wheel and which makes one revolution per day and which includes a sky disc with a depiction of the sun, and an aperture opposite this sun, through which is visible one part of this moon disc illustrating the current appearance of the moon.
Abstract:
The invention relates to a mechanism for driving a jumping element comprising a drive wheel (1), an indicator of a unit of time, a jumping element (6) integral with said indicator and coaxial to said drive wheel (1) to which said jumping element (6) is coupled by a spring (8), a cam (12) arranged to rock a pallet-lever (20) in an oscillating motion so as to release the jumping element (6) once per unit of time. According to the invention, the cam (12) and the jumping element (6) have distinct pivot arbors, said drive mechanism, further comprising an intermediate train kinematically connecting the drive wheel (1) to the cam (12), and the pallet-lever (20) has four distinct arms (20a, 20b, 20c, 20d), two (20a, 20b) of the four arms forming feelers arranged to cooperate with the cam (12) and the other two arms (20c, 20d) forming escapement arms arranged to successively block and release the jumping element (6) once per unit of time, alternately.
Abstract:
The regulating device includes an inertial balance (7) including a balance staff arranged to be pivotally mounted in the timepiece, a balance bridge (9) and a bearing (11) carried by the balance bridge and arranged to hold one end of the balance staff, a balance spring (1) including an inner end integral with the balance and an outer end (1a) integral with a stud (3; 103), and a mechanism for securing the stud (3; 103) including a housing (17) for receiving the stud and which is formed in a stud holder (5) pivoted on the balance bridge (9), the securing mechanism further including an elastic arm (15; 115) arranged to pivot concentrically to the balance staff between a first position where the elastic arm immobilizes the stud (3; 103) and a second position where the elastic arm is disengaged from the stud to allow the stud to be inserted into or removed from the housing.

Abstract:
Timepiece display mechanism including a cam driven by a time base, and a pivoting lever including an elastically returned feeler member following the contour of the cam and a first rack meshing with a first angular orientation wheel which drives an indicator plate synchronously or via a differential mechanism, the indicator plate projecting radially with respect to a main axis and being parallel to or coplanar with the first wheel, the display mechanism includes a connecting rod articulated at a first end to a carriage slidably mounted on the indicator plate and carrying a retractable hand, a second end of the connecting rod being pivoted on a fixed pivot or on a movable pivot comprised in an elongation wheel set driven directly or indirectly by the lever.
Abstract:
Timepiece or watch (1000) or music box including an acoustic display mechanism (100), for a striking timepiece (1000), including a plurality of control-pieces (1) for the same time measurement parameter, staged in parallel planes, and further including melody selection means (3), arranged to be operated by a user or by the timepiece movement, controlling or prohibiting, at a given moment, access of the control-pieces (1) to a common snail (2) corresponding to said time measurement parameter, to allow only one of the control-pieces (1) to operate at least one lever (4) controlling the motion of a hammer to play a melody that is specific thereto or to activate at least one gong that is specific thereto.
