ABSTRACT:
Each of the two alternately actualable clutches of a threading shaft includes a clutch disc keyed to the shaft, and positioned between two annular members. One of the members is rotated coaxially of the shaft by a driving gear, and the other is movable axially by the ball detents of a camming mechanism in one direction to grip the clutch disc frictionally between the annular members thereby to transmit the rotation of said driving gear to the shaft, and in the opposite direction to disengage the driving gear from the shaft.
