Abstract:
Apparatus for converting wind energy into electrical energy with the use of a generator, the apparatus comprising a support arm adapted for mounting on the ground or a building and having a pivot arm pivotally mounted on said support arm, said pivot arm having one end remote from said support arm and a pivot axle carried on said one end, at least one vane structure rotatably mounted on said pivot axle, said pivot arm being constrained to pivot in a selected plane and said pivot axle extending generally perpendicular to said selected plane, said pivot arm including limit structure for allowing rotation of said vane through a selected arc so that, in a wind current, said vane will assume a position tending to impart pivoting movement of said pivot arm relative to said support arm, wherein said pivot arm includes an extension located on the opposite side of said support arm, said extension being connected by an arm link to an electrical generator.
