THREE SPEED DECK WINCH Abstract of the Disclosure A deck winch provides three separate speed ratios for its drum when its main shaft is turned. With an external control lever in a neutral position a high speed ratio is attained by rotation of the main shaft in a first direction, resulting in a low drum speed. A medium speed ratio is attained by rotation of the main shaft in a second, opposite direction. With the control lever in its active or low gear ratio position, rotation of the main shaft in the first direction moves the drum at its highest speed relative to the main shaft. When the control lever is in this active position and the main shaft is rotated in the second direction, the control lever is automatically shifted to its neutral position and the medium speed ratio is established. The control lever is connected internally to engage and disengage an idler gear that mechanically interconnects the main shaft with one or several driving gears for the drum. At any time the position of the control lever and the direction of main shaft rotation may be selected to provide any of the three speed ratios.
