Wind driven apparatus is disclosed in the form of a windmill, and in the form of an electric generating unit for a vehicle such as a boat or an airplane or the illustrated automobile. The apparatus includes a base mounted for rotation, preferably about a vertical axis, and along its periphery carrying a series of cones each with an open mouth for receiving air or other fluid, to rotate the base about its axis. The apex of the base deflects the air as the apex moves into the direction of flow of the air. A partition secured across the cone inwardly of the mouth limits the amount of fluid received in the mouth and prevents passage of the fluid to the apex of the cone. When installed as a windmill, the base is horizontally mounted atop a column or other support and is drivingly connected with a pump or electric generator, or other suitable apparatus. As an electric generating unit for a vehicle the base is mounted within a housing having an air scoop for directing the air into the mouths of the cones as they are rotated past the inlet and the base is fixed to an axial shaft connected through a speed regulating mechanism for driving an electric generator connected with batteries or other equipment. An adjustable baffle is provided for limiting the flow of air into the scoop, and for closing the scoop to the passage of air, if desired.
Wind driven apparatus comprising, a base, means mounting said base for rotation about an axis, means responsive to the flow of wind past the base for rotating the base about said axis, said means including a plurality of wind receiving members operatively associated with the base and each having a mouth for receiving the wind passing the apparatus and responsive thereto rotating the base about said axis, and each member having a closed end opposite said mouth and converging from said mouth toward said end for deflecting the wind about the member, each member further including means spaced slightly inwardly of the outer periphery of the mouth and defining an inner portion of the mouth and substantially preventing passage of wind from said mouth into said end portion, said members being mounted on said base in a spaced apart series about said axis with the mouth of each member spaced from the end of the adjacent member and facing in a generally contrarotational direction of said base with the mouth substantially unobstructed by the adjacent end as the mouth moves into the path of the wind, and the converging ends directed in the rotational direction of said base.
