Abstract
A winch wherein a rope or cable is self-feeding onto a sheave by a spring that is biased so as to push a rope into contact with a grooved outer surface of the sheave. One end of the spring is pivotally supported on a frame that supports the sheave for rotation about its central axis, while the opposite end of the spring is freely flexible. A supporting block is provided for the free end of the spring to support and minimize or prevent damage to the spring. The block has an angled surface for urging the rope away from the sheave, thus, together with a stripper member, assisting removal of the rope from the sheave at a point at which the rope exits the sheave.
