Abstract
Abstract A wind machine which includes turbine assemblies arranged in superposed relationship and wherein the turbine assemblies may vary in size and number in accordance with power requirements, together with a plurality of deflector panels or sails associated with the turbine unit of each assembly for directing the wind to selected areas of the driving vanes of each turbine unit and at the same time shielding from the wind other areas of driving vanes which would tend to interfere with desired rotation of the turbine unit. The deflector panels or sails also accurately controlling the volume of air which bypasses each panel or sail to thereby prevent "stacking" or turbulence adjacent the driving vanes of the turbine unit. The panels also being arranged to recapture the major portion of the bypassed air and direct it back into the turbine unit which increases efficiency of operation.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
269 words
A wind machine comprising. a vertically extending support structure formed of an open framework through which the wind can freely pass, a vertical shaft disposed centrally of said structure, a turbine assembly mounted upon the support structure and exposed to the wind, which may blow through the framework, said turbine assembly including (a) a rotatable turbine unit having driving vanes, and (b) a plurality of deflector panels spaced peripherally about the turbine unit, with each panel being disposed at a generally tangential angle with respect to the periphery of the turbine unit and its driving vanes and extending from the outer limits of the support structure to a point adjacent to the periphery of the turbine, each panel when in the path of the wind direction acting to direct the wind which strikes the panels to deflect, channel and concentrate the wind flow to selected driving vanes of said unit and thereby impart rotation to the unit, means mounting each panel for individual angular adjustment with respect to the vanes of the turbine, additional means for mounting each panel for individual independent movement between the inner vertical edge of each panel and the periphery of the turbine unit to thereby control the wind flow passing between the said inner vertical edge of the panel and the periphery of the turbine unit, means connecting the turbine unit to said vertical shaft which extends within the support structure, and apparatus located at the lower end of the support structure and having connection with the vertical shaft, whereby said apparatus is driven by said shaft which is rotated by the turbine unit.
Claim 2
Dependent Claim
269 words
A wind machine comprising. a vertically extending support structure formed of an open framework through which the wind can freely pass, a vertical shaft disposed centrally of said structure, a turbine assembly mounted upon the support structure and exposed to the wind, which may blow through the framework, said turbine assembly including (a) a rotatable turbine unit having driving vanes, and (b) a plurality of deflector panels spaced peripherally about the turbine unit, with each panel being disposed at a generally tangential angle with respect to the periphery of the turbine unit and its driving vanes and extending from the outer limits of the support structure to a point adjacent to the periphery of the turbine, each panel when in the path of the wind direction acting to direct the wind which strikes the panels to deflect, channel and concentrate the wind flow to selected driving vanes of said unit and thereby impart rotation to the unit, means mounting each panel for individual angular adjustment with respect to the vanes of the turbine, additional means for mounting each panel for individual independent movement between the inner vertical edge of each panel and the periphery of the turbine unit to thereby control the wind flow passing between the said inner vertical edge of the panel and the periphery of the turbine unit, means connecting the turbine unit to said vertical shaft which extends within the support structure, and apparatus located at the lower end of the support structure and having connection with the vertical shaft, whereby said apparatus is driven by said shaft which is rotated by the turbine unit.
Claim 3
Dependent Claim
39 words
A wind machine as set forth in claim 1, wherein each deflector panel of the turbine assembly is of general rectangular shape, is disposed in a vertical plane and has a height substantially the height of the turbine assembly.
Claim 4
Dependent Claim
81 words
A wind machine as set forth in claim 1 wherein at least two deflector panels are located on the windward side of the turbine assembly with one of said panels disposed to protect the trailing sides of the vanes of the turbine unit from the wind and at the same time direct the wind toward the deflector panel which in turn directs the wind into those sides of the turbine vanes functioning to rotate said turbine unit in the desired direction.
Claim 5
Dependent Claim
61 words
A wind machine as set forth in claim 1, together with at least one additional turbine assembly superposed upon said first turbine assembly and also mounted upon the support structure, and means for connecting the additional turbine assembly or assemblies to the vertical shaft whereby said apparatus at the lower end of the support structure is driven by all turbine assemblies.
Claim 6
Dependent Claim
70 words
A wind machine as set forth in claim 1 wherein the vertical shaft is a one-piece shaft which is angular in cross section, upper bearing means mounted on the support structure and engaging the upper end of said shaft, and the lower bearing means also mounted on the support structure and engaging the lower portion of the shaft and located above the connection between the shaft and the driven apparatus.
Claim 7
Dependent Claim
86 words
A wind machine as set forth in claim 1, wherein said support structure is formed of (a) an inner vertically extending tower which is substantially square in cross-section and which is constructed of interconnected spaced apart members providing an open-type structural tower, and (b) an outer open-type structural tower also constructed of interconnected members which are connected to said inner tower, said outer tower having its main supporting members generally inclined with its base wider than its top to assure adequate support of said inner tower.
Claim 8
Dependent Claim
100 words
A turbine unit assembly for the vertical shaft of a wind machine as set forth in claim 1 wherein each deflector panel is constructed of a rigid material and is disposed in an upright vertical position, each panel being located so that its inner vertical edge is spaced from the periphery of the turbine unit, and additional means for individually adjusting each panel in a horizontal plane to vary the spacing of said inner vertical edge of each panel with respect to the turbine periphery in accordance with wind conditions to control the volume of air by-passing the turbine blades.
