<p>A self tailing winch with which a rope can be automatically pulled and paid out has a clamping ring attached to a rotary winch drum for rotation therewith. The ring has a central hub portion with a cylindrical surface that defines an annular groove with the end of the drum. The ring is yieldably urged against the end of the drum to clamp the rope. The rotary drum may be driven by a gear train from a rotated input shaft. A stationary annular plate fixed to a stationary frame is attached above the clamping ring and supports a downwardly and outwardly extending projection for deflecting the rope from the drum to the groove and also supports a device for paying out rope from the groove as the drum and ring are turned.</p> |
