ABSTRACT:
A deck winch for sailing craft provides a direct drive from main shaft to drum and has a self-tailing capability. Pawls mounted in the drum near its upper end extend through an arcuate opening in a stationary extended base member to engage the shaft intermittently. The base member affords a fixed mount at its upper end for the line lifter of a self-tailing device and comprises a cylindrical sleeve whose axis is offset from the axis of the main winch shaft. As a crank turns the shaft, each pawl progressively projects through the base member opening to drivingly engage the shaft for a portion of a revolution and then is cammed outwardly out of engagement as the next pawl takes over. The invention provides a relatively simple winch having both direct drive and self-tailing capabilities.
