An improved horizontally mounted wind wheel is provided which comprises a framework mounted for rotation in a horizontal plane on a central upright drive shaft, a plurality of secondary shafts supported for rotation on said framework near the periphery thereof, a vane mounted near one end thereof to each secondary shaft, a plurality of vane stops on the framework positioned radially inwardly of the secondary shafts for limiting the rotation of the vanes, each of said secondary shafts being mounted for rotation about an axis which is tilted with respect to a vertical to said horizontal plane whereby each vane has a preferred predetermined rest position defined by the direction of tilting of each axis from a said vertical.

In a windmill device including a wind wheel configured to rotate in a generally horizontal plane on a vertically disposed drive shaft, an improvement wherein said wind wheel comprises: a. means defining a framework mounted for rotation with said drive shaft in a generally horizontal plane; b. a plurality of second rotatable shafts supported by said framework in a radially spaced relationship to said drive shaft; c. a plurality of flexible vanes, each of said vanes mounted near one end thereof to a said second shaft for rotation therewith; d. each of said second shafts mounted for rotation about an axis which is tilted with respect to a vertical to said horizontal plane whereby each said vane has a preferred predetermined rest position defined by the direction of tilting of each said axis from a said vertical, each said axis being tilted at a tilt angle having a component in the same tangential direction and including a radially inwardly directed component, whereby said vanes, in their rest positions, are oriented substantially identically relative to a radius through their respective axes of rotation; and e. a plurality of vane stops disposed on said framework radially inwardly of said second shafts for limiting the rotation of each vane about its respective axis of rotation, said stops disposed on said framework to allow said vanes to rotate past said stops when said vanes are flexed to a predetermined degree.
