ABSTRACT:
An apparatus and method for incrementally advancing a shaft by a selected rotational amount. The apparatus includes a belt trained about a pair of space driven pulleys, the belt forming both first and second runs between the pulleys. Each pulley is associated with a shaft and is mounted for rotation in one direction only, with brake means designed to resist rotation of the pulley in the opposite direction. Means are provided for alternately deflecting the first and second runs of the belt to advance each shaft by an incremental amount in the one direction. In this manner, either or both shafts can be used for whatever purposes an incrementally advancing shaft is needed or desired.
