ABSTRACT:
A pair (20) of unidirection actuators are opposingly disposed coaxially about an elongated member (1) for controllably imparting a series of stepwise rotary movements thereto. An outer race (5) disposed within a housing (2) is rotationally reciprocated as a result of the axial reciprocation of a coaxial drive member (3) under the influence of reciprocation means (12, 15, 9). An overrunning clutch (6) converts the reciprocal rotary motion of the outer race (5) into a series of uniform unidirectional stepwise angular movements.
