ABSTRACT:
A reversible mechanism including a driven member with a rim having drive surfaces on its opposite sides. An elongate driving member is flexibly engageable with either of these surfaces at a predetermined position. The mechanism is useful in conjunction with a manually operated motor for controlled winding or unwinding of strands or yarns. It is also adaptable for reversal of movement by providing an extremity or extremities on the rim which, upon movement to the predetermined position, allow the driving member to disengage from one surface of the rim and to engage the other surface.
