Abstract
Abstract A winch particularly adapted for hauling lines on a sailing craft which will provide three wind-up speeds of the drum for one speed applied to a central shaft by a winch handle or a segment wheel attached to the shaft. Internally, the winch has a gear train mechanism including two rachet gears that provide two different drum speeds when the handle or segment wheel is rotated in opposite directions. A first speed is provided by an engaging means on the drum which causes it to be directly driven in one direction while overriding both ratchet gears of the internal gearing. The engaging means is retracted by movement of the handle or segment wheel in the opposite direction which thus drives the drum at a second speed through one ratchet gear of the internal gear mechanism. Another reversal of the handle or segment wheel causes the drum to be driven at a third speed through the other ratchet gear as long as the engaging means remains in its retracted position. The movable element of the engaging means may be situated in the end face of the drum or in the handle.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
170 words
A three speed deck winch adaptable for sailing boats comprising: a drum having a cylindrical body and an end face; a shaft extending through the central axis of said drum; a driving means attached to said shaft; internal gearing means and clutch means connected thereto within said drum body and engageable with said shaft for driving said drum at different speeds when said shaft is rotated at the same speed in both its clockwise and counterclockwise directions; and engaging means for directly interconnecting said driving means and said drum in one position so that rotation of said driving means in a first direction will rotate said drum at the same rate while overriding said internal gear means, said engaging means being movable by said driving means in a second direction opposite to said first direction to a fully retracted and disconnected position that allows said driving means to move over the end face of said drum and thereby operate said internal gearing to turn the drum at a different speed.

Claim 10
Dependent Claim
51 words
The deck winch as described in claim 8 wherein said synchronizing means comprises a generally annular plate having an opening with notches similar in shape to those of said opening in said drum end face, and a pair of projections on the periphery of said plate for engaging said pivotal pawl.
