A frame supported for rotation about a central vertical axis has an enclosing cylindrical side wall with a plurality of openings formed therethrough at spaced apart angular position around the central axis. A plurality of vanes are located near the side walls for causing the frame to be rotated by the wind. Each vane is associated with one of the openings and is supported for pivotal movement such that it may be moved through its associated opening between an inward position inside the side wall and an outward position wherein it extends outward beyond the side wall. Cams located at the central axis and cam followers are provided for cyclically moving each of the vanes to its inward and outward positions as the frame rotates such that on one side of the central axis, the vanes are moved to their outward positions to catch the wind as the vanes are rotated by the frame to this side and on the opposite side of the central axis, the vanes are moved to their inward positions out of the wind as the vanes are rotated by the frame to the opposite side.

A wind operated apparatus, comprising: a frame, support means for supporting said frame for rotation about a generally vertical axis, an enclosing side wall supported by said frame for rotation about said generally vertical axis, said enclosing side wall forming an interior chamber shielded from the wind, a plurality of openings formed through said enclosing side wall at spaced apart positions around said enclosing side wall, a plurality of vane means supported by said frame at spaced apart positions around said enclosing side wall and near said enclosing side wall for causing said frame and said enclosing side wall to be rotated by the wind, each of said vane means being associated with one of said openings, each vane means being supported for pivotal movement relative to said frame about a pivot axis such that it may be moved through its associated opening between inward and outward positions on opposite sides of said enclosing side wall, said pivot axes being located inward of said enclosing side wall, cam means supported by said support means at said generally vertical axis, a plurality of cam follower means coupled to said frame for rotation therewith and for engaging said cam means as said frame rotates, the number of said cam follower means being equal to the number of said vane means, each of said cam follower means being associated with one of said vane means, and linkage means pivotally coupled to each of said cam follower means and to its associated vane means, for cyclically moving each of said vane means to its inward and outward positions as said frrame rotates such that on one side of said generally vertical axis said vane means are moved to their outward positions as said vane means are rotated by said frame to said one side and on the opposite side of said generally vertical axis said vane means are moved to their inward positions as said vane means are rotated by said frame to said opposite side.
