ABSTRACT:
A fluid current motor adapted to extract energy from flowing natural currents is disclosed wherein a wheel-like frame is rotatably mounted about a vertical axis. The frame is positioned over a flowing water current, such as a stream, river, or the like, and is provided with a plurality of radial arms or spokes each of which is fitted with an articulated knuckle intermediate its length. At the outer extremity of each spoke there is mounted a yoke which pivotally supports a fluid reaction blade journaled intermediate its height in its associated yoke. Each yoke and blade assembly is buoyantly supported on the surface of the water by a pair of pontoons which maintain the blade at the same depth relative to the water surface regardless of variations in the level of the flowing water current. The reaction blades are provided at their vertical sides with hydrodynamic surfaces to effect more rapid pivoting of the blades into their vertically-oriented operative position and into their horizontal, feathered or inoperative position.
