Abstract
Abstract A wind powered electricity generation system having at least one wind vane assembly, an elongated shaft attached substantially perpendicularly to the bottom of the wind vane assembly, a tower supporting the shaft, and drive gears mounted on the shaft that are connected to an electricity generator. Each of the wind vane assemblies has a carrier member having a plurality of support arms extending outwardly from the carrier member in a horizontal plane. A plurality of elongated trough-shaped vanes are attached by fastener means to a point adjacent the ends of the support arms. The front side of the trough-shaped vanes point outwardly substantially perpendicularly from the lateral attaching surface of the support arms. Each of the trough-shaped vanes have a longitudinally extending axis that makes an angle between 30 degrees and 60 degrees with a vertical axis that pases through the point of attachment of the back of the trough-shaped vane and the support arm.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
A wind powered electricity generation system comprising: at least one wind vane assembly, said wind vane assembly having a carrier member, a plurality of elongated trough-shaped vanes, a plurality of support arms, fastner means attaching the back of said vanes to a point adjacent the ends of said support arms, the front end of said trough-shaped vanes pointing outwardly substantially perpendicularly from the lateral attaching surface of said support arms, each of said trough-shaped vanes having a longitudinally extending axis that makes an angle between 30 degrees and 60 degrees with a vertical axis that passes through the point of attachment of the back of the trough-shaped vane and the support arm, upstanding cleats on the surface of said trough-shaped vanes, said cleat being oriented in pairs that form the shape of an open bottom V-configuration; an elongated shaft attached substantially perpendicularly to the bottom of said carrier member; a tower supporting said shaft; and drive gear means mounted on said shaft, said drive gear means being connected to an electricity generator.
Claim 2
Dependent Claim
172 words
A wind powered electricity generation system comprising: at least one wind vane assembly, said wind vane assembly having a carrier member, a plurality of elongated trough-shaped vanes, a plurality of support arms, fastner means attaching the back of said vanes to a point adjacent the ends of said support arms, the front end of said trough-shaped vanes pointing outwardly substantially perpendicularly from the lateral attaching surface of said support arms, each of said trough-shaped vanes having a longitudinally extending axis that makes an angle between 30 degrees and 60 degrees with a vertical axis that passes through the point of attachment of the back of the trough-shaped vane and the support arm, upstanding cleats on the surface of said trough-shaped vanes, said cleat being oriented in pairs that form the shape of an open bottom V-configuration; an elongated shaft attached substantially perpendicularly to the bottom of said carrier member; a tower supporting said shaft; and drive gear means mounted on said shaft, said drive gear means being connected to an electricity generator.
Claim 3
Dependent Claim
34 words
A wind powered electricity generation system as recited in claim 1 further comprising a second wind vane assembly mounted on said elongated shaft at a position downwardly spaced from the other wind vane assembly.
Claim 4
Dependent Claim
167 words
A wind powered electricity generation system comprising: at least one wind vane assembly, said wind vane assembly having a carrier member, a plurality of elongated trough-shaped vanes, a plurality of support arms, fastener means attaching the back of said vanes to a point adjacent the ends of said support arms, the front side of said trough shaped-shaped vanes pointing outwardly substantially perpendicularly from the lateral attaching surface of said support arms, each of said trough-shaped vanes having the longitudinally extending axis that makes an angle between 30 degrees and 60 degrees with a vertical axis that passes through the point of attachment of the back of the trough-shaped vane and the support arm, said trough-shaped vanes having a semi-circular lateral cross-section and and being open on both of their opposite ends; an elongated shaft attached substantially perpendicularly to the bottom of said carrier member; a tower supporting said shaft; and drive gear means mounted on said shaft, said drive gear means being connected to an electricity generator.
Claim 5
Dependent Claim
