Wind powered apparatus for attachment to a generator is provided to produce electricity. A series of foldable sails are attached to an endless chain having upper and lower reaches. Guide means control the folding and unfolding of the sails as they travel along the chain. The surface of the unfolded sails always face the wind to obtain maximum benefit therefrom while the folded sails, which travel against the wind to return to an unfolded position, act as wind vanes to keep the sails in proper position with respect to wind direction. As one sail drops to the lower chain reach, another sail rises to the upper chain reach for maximum efficiency. A plurality of such chain assemblies are placed laterally adjacent one another to create a “wind platform”. Sprockets attached to the chain turn a shaft which powers a generator.

Wind powered apparatus for producing electricity comprising: a) an endless chain trained over and movable in a continuous path about two substantially spaced-apart sprockets, to define upper and lower, substantially horizontal chain reaches; b) a plurality of sails fixedly attached to said chain, said sails each including adjacent, first and second, superposable flaps having surfaces of substantially equal areas, said flaps being moveable between a first, open position wherein said surfaces are in laterally adjacent, subststantially co-planar relation and a second, closed position wherein said first and second flaps are folded about an axis perpendicular to said chain with said surfaces in facing, substantially superposed relation in a plane perpendicular to the plane of said sail when in said first, open position; c) guide means positioned adjacent said chain and operable to effect movement of said flaps into said first, open position when said sail travels with said chain along one of said reaches, and into said second, closed position when said sail travels with said chain along the other of said reaches; d) a rotary electrical generator; e) means connecting at least one of said sprockets to said generator to rotate the latter in response to movement of said chain by wind acting upon said sail flaps when in said first, open position thereof.
