Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
A wind driven power producing apparatus comprising a caster supported turntable, gear means carried by said turntable for transmitting the rotation of the upper extremity of said turntable to an electricity producing generator, arm and vane means carried by said apparatus and rotating in a horizontal plane for turning wind velocity into rotating torque for producing electricity, turntable, stop members, and spring means carried by said device for controlling the angle of said vanes, windless and trim motor means carried by said apparatus for controlling said turntable, a torque convertor, a gear box and a fly wheel means carried by said apparatus for the continuous producing of electrical power, a second torque convertor and a stand-by engine carried by said apparatus for emergency driving of said generator when wind velocity is reduced.
Claim 2
Dependent Claim
132 words
A wind driven power producing apparatus comprising a caster supported turntable, gear means carried by said turntable for transmitting the rotation of the upper extremity of said turntable to an electricity producing generator, arm and vane means carried by said apparatus and rotating in a horizontal plane for turning wind velocity into rotating torque for producing electricity, turntable, stop members, and spring means carried by said device for controlling the angle of said vanes, windless and trim motor means carried by said apparatus for controlling said turntable, a torque convertor, a gear box and a fly wheel means carried by said apparatus for the continuous producing of electrical power, a second torque convertor and a stand-by engine carried by said apparatus for emergency driving of said generator when wind velocity is reduced.
Claim 3
Dependent Claim
96 words
The combination according to claim 1, wherein the base of said turntable is stationary and said casters are regularly spaced apart and fixedly secured thereto and are in rolling engagement with a tire fixedly secured to an upper flange having teeth which engage the teeth of a gear secured to said first torque convertor and said gear box, said gear box, being secured by shaft means to said generator so that proper speed may be attained through the torque of the rotation of said turntable in order to produce electrical power by means of said generator.
Claim 4
Dependent Claim
47 words
The combination according to claim 2, wherein said rotation of said generator shaft simultaneously rotates said fly wheel, said fly wheel providing for rotation of said generator when wind velocity decreases so as to enable said standby motor to be started for rotating said generator if necessary.
Claim 5
Dependent Claim
140 words
The combination according to claim 3, wherein said flange member of said turntable has fixedly secured to it a vertical and hollow shaft to which trim cables are carried and said trim cables extend radially outwards and are secured to stop members attached to the upper and lower radial arms of said turntable, said stop members serving to control the angle of the pivotable vanes secured between said arms, said vanes being parallel, spaced apart and the extreme ends of said trim cables are secured to one end of contacting tension springs, the opposite ends of said contacting tension springs being secured to the outer extremities of said radial arms and by regulating the voltage said vanes may be released when excessive wind velocity occurs thus protecting said turntable of said apparatus from destruction due to excessive speed of rotation.
