ABSTRACT:
A driven gear (3a), a gear (11a) to a rotary solenoid (15a) and an output drive gear (19a) are mounted to rotate together, preferably as one part turning on a stationary shaft (7a). The driven gear and the output drive gear have disengagement sectors (5a and 20a). Activation of the solenoid turns the driven gear into engagement with a normally turning drive gear (1a). Shortly after the sector on the output gear is cleared, and the load (27) is driven through engagement with driven gear (23a). After one cycle, the detent force of the solenoid positions the sector 5a so that engagement is terminated. Because the rotary solenoid need only move the gears 3a, 11a and 19a, the size of the load is immaterial to the physical requirements for the solenoid and its reliability of operation.
