ABSTRACT:
The channel of a self-tailing winch is made up of two jaw members (5,17) interlinked by an arrangement such that when there is relative rotation between the jaws a relative axial displacement is imposed upon them by that relative rotation. Cam following studs (20) associated with one jaw engage in inclined camming slots (22) associated with the other. The inclination of the slots is preferably "positive" i.e. such as to cause closer axial approach of the jaws when there is any slippage.
