Patent ID: 7618237

Claim:
A vertical shaft wind driven power generating system, said system powered by the wind with movable vanes, said system comprising a. a vertical axis member for rotation about a vertical axis, b. a base member supporting said vertical axis member, c. at least two frame members on said vertical axis member and including two parallel strut members, d. each frame member consisting of a plurality of vane panels, each panel having a flat wind driven surface and edges, said vane panels being pivotally mounted on said frame between said parallel strut members to rotate therebetween through approximately ninety degrees, at least two vane panels on each frame member and said frame members being mounted 180 degrees apart from one another on said vertical axis member, e. journals mounted upon both parallel struts, and vertical rod means on said vane panels and extending through said journal to aid panels to alternately position their wind driven surfaces and their edges in the direction of the wind so as to continually rotate with the force of the wind on the surface of some of the vane panels, turning the vertical axis member, and f. each vertical rod having one bent portion extending beyond one of the journals to provide, in cooperation with the adjoining strut, to limit the rotation of each rod and accompanying panel member to 90 degrees.
