Abstract
This device for the simultaneous zero-resetting of two counters, the pivot axes of which are fixedly connected to respective heart-shaped zero-resetting cams (7, 8), comprises a zero-resetting lever (2) containing two hammers (6c, 6d), means (5) for exerting upon this lever (2) a torque for pressing the two hammers (6c, 6d) against the zero-resetting cams (7, 8), and articulation means (2d, 2e, 6a, 6b) for articulating these hammers relative to the lever (2). These articulation means comprise two pins (2d, 2e), one of which (2d) is engaged in a guide slot with limited amplitude (6a), orientated in order that the direction of the perpendicular, dropped from the axis of the pin (2d) onto this guide slot (6a), intersects the straight line joining the axes (7a, 8a) of the zero-resetting cams (7, 8) at a point capable of improving the distribution of the torque transmitted to these cams (7, 8).
