Abstract
Abstract A wind power generating system is provided to generate power for the farm or ranch, state or county service buildings, and light industrial uses. The concept utilizes wind energy efficiently to convert power and can be rendered inoperative to avoid destruction by excessive wind flows.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A wind power generating system comprising a shaped, closed, hollow central member having a generally circular cross section which is cylindrical in an intermediate part of said member, tapers forwardly and inwardly to a nose at the front and tapers rearwardly and inwardly to a back area, a plurality of open cylindrical shrouds fixedly mounted around the outside of said central member and supported at least in part by the outer surface of said central member, fins mounted forwardly on the outer surface of said central member and extending outwardly therefrom and tangentially against adjacent shrouds to channel wind flow to said shrouds, a propeller mounted centrally on a shaft in each of said shrouds, each said propeller adapted to be driven by wind passing over the nose and forward of said central member, and means responsive to the rotation of said propellers operative to generate electrical power.
Claim 2
Dependent Claim
148 words
A wind power generating system comprising a shaped, closed, hollow central member having a generally circular cross section which is cylindrical in an intermediate part of said member, tapers forwardly and inwardly to a nose at the front and tapers rearwardly and inwardly to a back area, a plurality of open cylindrical shrouds fixedly mounted around the outside of said central member and supported at least in part by the outer surface of said central member, fins mounted forwardly on the outer surface of said central member and extending outwardly therefrom and tangentially against adjacent shrouds to channel wind flow to said shrouds, a propeller mounted centrally on a shaft in each of said shrouds, each said propeller adapted to be driven by wind passing over the nose and forward of said central member, and means responsive to the rotation of said propellers operative to generate electrical power.
Claim 3
Dependent Claim
198 words
A wind power generating system comprising a shaped, closed, hollow central member having a generally circular cross section which is cylindrical in an intermediate part of said member, tapers forwardly and inwardly to a nose at the front and tapers rearwardly and inwardly to a back area, a plurality of open cylindrical shrouds fixedly mounted around the outside of said central member and supported at least in part by the outer surface of said central member, a propeller mounted centrally on a shaft in each of said shrouds, each said propeller adapted to be driven by wind passing over the nose and forward of said central member, said propellers being rotatably mounted for movement from a normal operating position in a vertical plane to a position where they are not affected by high winds, said movement being effected in response to independent fluid pressure stored in a receiver tank, said fluid pressure being controlled by a valve disposed in said central member and actuated electrically from a switch operated in response to wind pressure and disposed in the forward portion of said central member, and means responsive to the rotation of said propellers operative to generate electrical power.
