Abstract (en)
The device has a cam plate (9) with a pallet connected to a control wheel (2), and a pivoting lever (13) with a sensor (15) cooperating with a peripheral surface of the plate. A barrel (23) has a cylinder (22) carrying a snail cam (24). A finger (17), a ratchet (33) and pull-off springs (21, 35) constitute a blocker, which is activated when the sensor falls from the pallet for releasing the cylinder such that the barrel is withdrawn at a preset angle. A lever (26) has a sensor (25) cooperating with the cam, where a free end of the lever (26) activates a push button (29) of an equalizer (30).
Abstract (fr)
Le dispositif de déclenchement d'impulsion mécanique comporte des premiers moyens (2, 6, 9, 13, 17) entraînés par un mouvement d'horlogerie déterminant le moment où une impulsion doit être délivrée et des seconds moyens (22, 23, 24,26,30,31, 33), déclenchés par les premiers moyens, délivrant une impulsion mécanique de force et d'amplitude prédéterminées à partir d'un organe moteur (22, 23) indépendant du mouvement d'horlogerie.
