ABSTRACT:
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.
