Abstract

The timeplace balance mechanism includes an intermittently rotating indexing wheel (11). This base a blocking wheel (13) of smaller diameter fixed to it, with a pivoted blocking lever (18) resiliently engaging the peripheral surface of the blocking wheel (13). The print of application of the blocking lever (18) on the blocking wheel (13) is pref. adjacent a line joining the pivot axis of the blocking lever and the axis of the indexing wheel (11) and blocking wheel (13). The indexing wheel (11) pref. has a number of indexing pins (12) spaced around its periphery, which cooperate with a spiral rib (7) around the surface of a drive element (6) rotating back and forth.
