Abstract
Abstract A wind driven prime mover which is driven by a plurality of arcuately shaped wind vanes pivotally mounted on a rotatable turntable. The wind vanes are pivotally mounted on the turntable with their pivot axle disposed in a vertical plane. The pivots are positioned adjacent the periphery of the turntable, with the pivots being spaced equi-distant from each other and equi-distant from the axis of rotation of the turntable. The bottoms of the vanes are arcuately shaped, with the length of the arc being slightly longer than the space between the pivots so that there is an overlap between adjacent vanes. The convex surface of the vanes face outwardly to provide a concave inner surface.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
In a wind driven power producing apparatus, a wind driven prime mover comprising a rotatable circular turntable having an axial (shaft) rotatably mounted on a fixed base, a plurality of arcuate shaped wind vanes automatically opened and closed solely by wind action, said vanes being pivotally mounted on the turntable (at right angles) parallel to the axis of rotation of the turntable, said pivots being located substantially centrally between the outside edge and inside edge of the vane, the vanes being of a length that in a closed position the (leading) inside edge of one vane will (overlap) underlie the (trailing) outside edge of the preceding vane and (stop means limiting the pivot movement of the vanes to an) in the open position in response to the wind velocity the inside edge will engage against the axial shaft.
Claim 2
Dependent Claim
138 words
In a wind driven power producing apparatus, a wind driven prime mover comprising a rotatable circular turntable having an axial (shaft) rotatably mounted on a fixed base, a plurality of arcuate shaped wind vanes automatically opened and closed solely by wind action, said vanes being pivotally mounted on the turntable (at right angles) parallel to the axis of rotation of the turntable, said pivots being located substantially centrally between the outside edge and inside edge of the vane, the vanes being of a length that in a closed position the (leading) inside edge of one vane will (overlap) underlie the (trailing) outside edge of the preceding vane and (stop means limiting the pivot movement of the vanes to an) in the open position in response to the wind velocity the inside edge will engage against the axial shaft.
Claim 3
Dependent Claim
53 words
In a wind driven power producing apparatus according to claim 1, in which the pivot of each vane is positioned adjacent the arcuate bottom and substantially equi-distant between the ends thereof, the pivots of the respective vanes being spaced equi-distant from each other and equi-distant from the axis of rotation of the turntable.
Claim 4
Dependent Claim
29 words
A wind driven power producing apparatus according to claim 1 in which the stop member comprises a rubber-like cushion enclosing said shaft to cushion the opening of said vanes.
Claim 5
Dependent Claim
33 words
A wind driven power producing apparatus according to claim 1, in which the stop member comprises an inflatable sheath enclosing said shaft and means automatically inflating said sheath relative to the wind velocity.
Claim 6
Dependent Claim
103 words
In a wind driven power producing apparatus, a wind driven prime mover comprising a circular turntable having an axial shaft rotatably mounted on a fixed base, a plurality of arcuate shaped wind vanes pivotally mounted on the turntable, the vanes being of a length that in a closed position the outside edge of one vane will underlie the inside edge of the preceding vane, stop means limiting the pivot movement of the vanes to an open position in response to wind velocity, said stop member comprising an inflatable sheath enclosing said shaft and means automatically inflating said sheath relative to the wind velocity.
Claim 7
Dependent Claim
103 words
In a wind driven power producing apparatus, a wind driven prime mover comprising a circular turntable having an axial shaft rotatably mounted on a fixed base, a plurality of arcuate shaped wind vanes pivotally mounted on the turntable, the vanes being of a length that in a closed position the outside edge of one vane will underlie the inside edge of the preceding vane, stop means limiting the pivot movement of the vanes to an open position in response to wind velocity, said stop member comprising an inflatable sheath enclosing said shaft and means automatically inflating said sheath relative to the wind velocity.
Claim 8
Dependent Claim
77 words
In a wind driven power producing apparatus according to claim 5, in which the means for automatically inflating the sheath comprises an air scoop rotatably mounted atop said shaft, a wind tunnel through said scoop having its entrance constantly facing into the wind and its exit communicating through holes in said shaft with said sheath whereby the air pressure, created by the wind, within the sheath inflates and expands the sheath directly proportional to the wind velocity.
