ABSTRACT:
A cable winch having a pair of cable-gripping assemblies movably mounted on a support member adapted to be secured to a fixed point. An operating handle is pivoted to the support member, and linkages interconnect the handle with each of the assemblies to effect movement of the assemblies on the support member. A cable is winched by the assemblies alternately gripping, pulling, releasing and re-gripping the cable as the handle is operated. A kicker bar is pivotally supported adjacent to one of the gripping assemblies and coacts therewith to ensure that the movable gripping surface of the assembly positively releases its grip on the cable to ensure passage of the cable therethrough, while the remaining gripping assembly maintains its grip on the cable.
