ABSTRACT:
A winch or capstan primarily for tightening the sails of a ship and having a winch head driven always in one direction only at a selected one of four speed ratios. A planetary transmission and free wheel arrangement provide two of the speed ratios corresponding to clockwise and counter-clockwise rotation of a control shaft. A sprocket and chain arrangement drive by handwheels is housed in two casings mounted at one end of the shaft, the driven sprocket in one casing being moveable into dog-clutch engagement with one or the other of two gear trains coupled with the shaft to provide the two further speed ratios.
