Abstract
A clutch element fastened to the end of a sewing machine main shaft by a shouldered screw is slidable thereon to a first position wherein axially extending clutch fingers thereof extend through guide notches in an interlock element fixed to the main shaft by the shouldered screw, into axially aligned recesses in a belt driven handwheel so as to drive the sewing machine main shaft. In a second position of the clutch element, the axially extending fingers thereof are withdrawn from the recesses in the handwheel so that the sewing machine main shaft is not driven. Detent means are provided to maintain the clutch element in a selected position.
