ABSTRACT:
A sail-driven wind motor (SDWM) is described, in which a reciprocating load amenable to intermittent, bidirectional drive (such as a water pump or air compressor) is driven by one or two arms, with each arm driven by at least one conventional fore-and-aft rigged sail. Masts for the sails are mounted on beams which are pivotally mounted on the arms. At least one mast and sail per beam, and at least one beam per arm are required to drive the load. Mechanisms are described for controlling the sails to drive the load, and to stop operation of the SDWM during excessive wind velocity. SDWMs for three types of sites are described: land, shallow water, and deep water. Each arm is supported by at least one cross-arm, which rides on wheels for a land site, or on at least one double-ended float for water sites. For all three types of sites, the sail drag must be transferred to the ground, while the sail lift must be transferred to the load via the arm. A mechanism is described for transferring the sail drag to the ground.
