Sail-driven wind motor

A sail-driven wind motor, comprising:

• a stator adapted to be supported on a foundation, a rotor associated with said stator and journalled for rotation with respect thereto, a rotary drive means operatively associated with said rotor for imparting rotary motion to said rotor upon rotation thereof, and an arm means operatively connected at a point thereon with said rotary drive means in cranking relation thereto so that as said arm means is reversingly rotated in a generally horizontal plane about said point said rotary drive means is correspondingly reversingly rotated, said arm means having at least one portion which extends radially outwardly from said point, each such arm portion having a radially outer end located distally of said point;
• at least one sail assembly including at least one sail fore and aft rigged to a respective subassembly of an erect mast and generally horizontal beam;
• means mounting each said mast and beam subassembly to a respective said arm portion, distally of said point, for rotation about a generally vertical axis, with each beam being disposed athwart the respective arm portion;
• and
• rigging means operatively associated between each said mast and beam subassembly and the respective said arm for automatically reversingly, oscillatingly tacking said sail with respect to a wind heading direction upon clockwise and counter-clockwise extremes of rotation of said arm means caused by wind-induced lift on said at least one sail and thereby reversingly rotating the respective said arm throughout a circular arc of less than 360.
