Abstract
An apparatus is provided for turning a rotor for each desirable angle by a capstan drive system wherein an eccentric free travelling ring carried by a turnable lever at a point removed from the pivot end of the lever is thus contactable and discontactable with a rotary shaft of the capstan drive system. A small gear is connected to the free travelling ring and is engaged with another large rotor gear for reducing the rotation thereof, the large gear being pivotally mounted on the pivot bearing of the turntable lever. Means are provided for biasing the free travelling ring toward the rotary shaft of the capstan drive system and further control means are provided for interlocking the free end of the turntable lever so as to prevent contact of the free travelling ring with the rotary shaft of the capstan drive system.
