Abstract
Abstract A wind-powered energy producing device comprising a Venturishaped chamber mounted for rotation on a support, a rudder adapted to be acted upon by the wind to orient the openings of the chamber into the wind, and a fan positioned within the throat of the chamber to be acted upon by the wind entering the chamber, the fan being operatively connected to an energy producing device such as a generator or the like.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
192 words
A wind-driven energy-generating device comprising a Venturishaped chamber having a central throat portion and enlarged end portions at opposite sides of said throat portion, one end portion being an upstream end portion and the other a downstream end portion, both of said end portions being open, said chamber being mounted for rotation on an axis provided by a first support means, a second support means extending into said throat portion, said second support means being positioned downstream from said first support means whereby said second support means is eccentric to said first support means, an energy generating means mounted on said second support means, a fan connected to said energy-generating means, Said fan being mounted for rotation on said second support means within said throat portion, said throat portion being free of fixed blade construction, said fan being radially spaced from the wall area defining said throat portion, said second support means, energy generating means and fan having a center of gravity offset from said axis provided by said first support means and a wind-operable orienting rudder, said rudder extending longitudinally of said chamber and being positioned radially outward of said chamber.
Claim 2
Dependent Claim
192 words
A wind-driven energy-generating device comprising a Venturishaped chamber having a central throat portion and enlarged end portions at opposite sides of said throat portion, one end portion being an upstream end portion and the other a downstream end portion, both of said end portions being open, said chamber being mounted for rotation on an axis provided by a first support means, a second support means extending into said throat portion, said second support means being positioned downstream from said first support means whereby said second support means is eccentric to said first support means, an energy generating means mounted on said second support means, a fan connected to said energy-generating means, Said fan being mounted for rotation on said second support means within said throat portion, said throat portion being free of fixed blade construction, said fan being radially spaced from the wall area defining said throat portion, said second support means, energy generating means and fan having a center of gravity offset from said axis provided by said first support means and a wind-operable orienting rudder, said rudder extending longitudinally of said chamber and being positioned radially outward of said chamber.
Claim 3
Dependent Claim
13 words
The device of claim 1 wherein said energy-generating means is an electrical generator.
Claim 4
Dependent Claim
20 words
The device of claim 1 wherein said energy-generating means is connected to a mechanical transmission system for generating mechanical energy.
Claim 5
Dependent Claim
32 words
The device of claim 1 wherein at least one vane is provided on the inner peripheral surface of the chamber adjacent said front opening, said vane extending radially inward of said chamber.
Claim 6
Dependent Claim
18 words
The device of claim 4 wherein there are a plurality of vanes radially spaced equidistantly from each other.
Claim 7
Dependent Claim
29 words
The device of claim 1 wherein said first support means is a rotatable turntable, the axis of rotation of said turntable being the axis of rotation of said chamber.
Claim 8
Dependent Claim
53 words
The device of claim 1 wherein said rudder has a narrow portion and a wide portion, said narrow portion being adjacent to but radially spaced from the open end of said upstream end portion and said wide portion being adjacent to but radially spaced from the open end of said downstream end portion.
Claim 9
Dependent Claim
26 words
The device of claim 1 wherein said rudder has a length corresponding to the length of said chamber and is provided with a longitudinal streamlined configuration.
