Wind-driven twin turbine

A wind driven turbine assembly useful for the generation of electricity comprising:

• a frame having a front opening for the entrance of a flow of wind, said frame having a floor, a right side, a left side, a top and a back;
• a right and a left turbine rotatably supported by the top and floor of said frame each of said right and left turbines:
• having a vertically oriented central support pipe having a plurality of air passageways therethrough;
• a plurality of blades held by each of said vertically oriented support pipes, said blades being generally vertically oriented and extending generally radially outwardly to an outer edge from said central support pipes so that as each turbine rotates its outer edge subscribes a circle within said frame, each circle having an outer edge orientated near the respective right side and left side of said frame;
• each central support pipe having an upper and a lower end support frame for providing support means for holding the support pipe in a vertical position and at least one of said upper and lower end support frame having openings to permit the flow of air outwardly from an inner area of said support pipe;
• a nose cone supported vertically in the front opening of said frame having a rightwardly oriented face and a leftwardly oriented face for diverting the flow of wind away from a center of said front opening of said frame to create a right air stream and a left air stream;
• a right side door and a left side door each hingedly held across the right and left sides respectively of said frame by a vertical hinge positioned nearer the front opening of the frame than the back of the frame said right side door and said left side door being movable from a closed position angularly progressively to let more wind pass between the outer edges of said blades and the respective side door, each side door being biased toward a closed position whereby a right side air stream flows against the blades of said right turbine and along said right side door and a left side air stream flows against the blades of said left turbine and along said left side door thereby urging said turbines to turn in opposite directions;
• a back panel held across a central area of said back of said frame, said back panel, said top, bottom said right turbine and said left turbine forming a rear central space, said back panel having a right edge and a left edge;
• means for releasing air from said rear central space to the outside of said frame;
• a right and a left adjustable baffle are held across the back of said frame adjacent said back panel, said right and left adjustable baffles each hingedly held at said right edge and said left edge of said back panel;
• and
• means for setting the amount of opening of said right and left adjustable baffles whereby when a stream of air enters the front opening of the frame, such stream is directed by the nose cone into a right air stream and a left air stream, the right air stream passing against turbine blades on the right side of the support pipe of the right turbine and against the right side door and against the right side baffle, a portion of the air stream passing through said air passageways in said vertically oriented central support pipe of the right turbine and the left air stream passing against turbine blades oh the left side of the support pipe of the left turbine and against the left side door and against the left side baffle, a portion of the air stream passing through said air passageways in said vertically oriented central support pipe of the left turbine;
• and
• electrical generating means operably connected to said right turbine and said left turbine to produce electrical energy.
