Abstract

709,201. Wind-motors. MINING & LAND SYNDICATE, Ltd. Oct. 12, 1951 [Oct. 12, 1950], No. 24980/50. Class 110(3) In a windmill having a rotor assembly comprising vertical vanes 1 mounted on a base 2 and arranged symmetrically about a vertical axis, the assembly floats in a water tank 5 and means are provided for preventing movement of the rotor at right angles to the axis of rotation whilst permitting tilting movement of the rotor about axis at right angles to the axis of rotation. The rotor shaft is splined to the rotor and drives an electric generator disposed beneath the rotor assembly, through a universal joint 11 and a shaft 10. The vanes of the rotor may be inter-conneeted at their upper ends by a ring or by stays or covered with an annular plate or frame. The vanes, base, float 4 and tank are made of concrete. The water level in the tank 5 may be controlled and braking effected by lowering the water level until the floats 4 contact walls 6. 7 in the tank. Wheels or rollers may be interposed between the rotor assembly and the side of the tank and the wheels may constitute pinions engaging one or more toothed rings fixed around the circumference of the rotor assembly. The shafts of the pinions may drive electric generators directly or through gearing. The float 4 may constitute an air bell, the rotor being raised or lowered by varying the amount of air trapped therein. In a modification, the vanes are replaced by metal or fabric sails which are supported between upper and lower booms pivoted, intermediate their end and centre portions, on masts. The adjacent ends of each set of booms are interconnected by chains which may inconporate shock absorbers or springs. The float is fixed to a central driving disc by rods or tensioned chains.
