Abstract

The mecanism consists of a first star wheel (2) mounted on the hour wheel (1), a second star wheel (3) freely mounted on the hour wheel spindle, a third star wheel (8) with a profile identical to the first two and whose teeth are engaged with the teeth of the first two star wheels, a first sprung arm (7) for positioning the second star wheel (3) and a second sprung arm (9) for positioning the third star wheel (8). The star wheels are provided with twelve or twenty four teeth and the force of the second sprung arm (9) is greater than that of the first (7). A disk (6) mounted on the second star wheel (3) rotates by instantaneous shifts.
