ABSTRACT:
A windmill, comprising an axial support mounted for rotation about its vertical axis, elongated shaft sections arranged radially about the axial support, and a pair of vanes attached to each shaft section spaced about the axial support at right angles to each other for rotation about the axis of the axial support. A frame is included for attaching the shaft sections to the axial support, and a pillow block included with the frame provides a pivotal connection between the frame and shaft sections for allowing the shaft sections to rotate about their axis. A pair of counterweights attached laterally outward from each shaft section and positioned obtusely from the vanes in an alignment coaxial with its shaft section have a spaced configuration about the axial support for balancing the vanes dynamically about the axis of the axial support, when the vanes are rotated about the axis of the axial support, the counterweights further balancing the vanes axially about the shaft sections.
