Title: (EN) Winding arrangements
Abstract:
(EN)

A winding arrangement suitable for sheeting in a sail of a yacht comprising a winch drum and a piston cylinder assembly having a double-acting piston which is reciprocable within a cylinder. A rack member, coupled to the piston, produces unidirectional rotation of the winch drum through a particular clutch and gear system. A manually operated pump is arranged to supply fluid under pressure to the piston-cylinder assembly through supply pipes and a valve which directs the fluid supplied by the pump to opposite ends of the cylinder alternately, thereby to reciprocate the piston and rotate the winch drum.
