Abstract
A wind turbine is arranged to provide for a front torroidal plate mounted from and spaced relative to a rear solid plate coaxially securing a deflecting cone coextensively and coaxially between the front and rear plate, with a series of equally spaced arcuate impeller blades mounted adjacent a periphery of the front and rear plates exteriorly of the cone to direct air flow through the turbine plates from the cone structure. The impeller also has a fluidic rotation indicator. The indicator is a set of arcuate liquid chambers which contain two different fluids of different colors and specific gravities. When the impeller is stationary, the two different fluids separate, indicating two colors. However, when the impeller rotates, the two fluids mix and indicate a single third color.

Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIGS. 1 to 10 thereof, a new and improved wind turbine apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
More specifically, the wind turbine apparatus 10 of the instant invention essentially comprises an impeller housing 11, such as illustrated in FIG. 1, including a front torroidal plate 12 defined by a predetermined diameter spaced from and parallel a rear plate 14 defined by a diameter substantially equal to the predetermined diameter coaxially aligned relative to the front plate 12. The front plate 12 further includes a central opening 13, with an axle shaft 15 coaxially and integrally mounted relative to the rear plate 14 extending at least to the front plate 12 and extending rearwardly and coaxially relative to the rear plate 14. A plurality of spaced radial brace legs 16 are radially adjacent the outer periphery of the front torroidal plate 12 radially thereof interiorly of the front plate 12 to define a central brace leg bearing ring fixedly receiving the forward terminal end of the axle shaft 15. A central cone 18 whose base is fixedly mounted on a forward surface of the rear plate 14 includes its apex positioned adjacent the central brace leg bearing ring 17 coaxially aligned with and mounted about the axle shaft 15. A plurality of spaced arcuate vanes 19, each defined about an equal radius of curvature whose axes are arranged parallel relative to one another and to the axle shaft 15 and mounted coextensively between the front plate 12 and the rear plate 15 exteriorly of the central cone 18. The vanes 19 are each canted to include an outer edge adjacent a periphery of the front and rear plates 12 and 14, with an inner edge positioned in a spaced relationship relative to the outer periphery of the front and rear plates, with the outer and inner edges of each vane arranged in a parallel relationship relative to themselves and the other vanes of the organization.
Reference to the FIG. 5 illustrates the use of a first support housing 20 positioned rearwardly of the impeller housing 11 and below the axle shaft 15 mounting a support cage 21 to a top surface of the first support housing 20 rotatably receiving the axle shaft 15 therethrough, with a first gear 23 mounted to the axle shaft within the cage 21 cooperating with the second gear 24 mounted to an upper terminal end of a first output shaft 25. A third gear 26 is mounted adjacent a lower distal end of the first output shaft 25 in communication with the fourth gear 27 mounted to a second output shaft 25a. An electric generator mounted to the second output shaft 25a is arranged for the production of electrical energy.
In a similar manner, auxiliary solar panels 29, such as illustrated in FIG. 7, may be utilized to cooperate in concert with the electrical generator in providing a continuous supply of electrical energy.
The FIGS. 9 and 10 illustrate the use of a modified rear plate 14 and front plate 12 respectively. The rear plate 14 illustrated in FIG. 9 is arranged to pivotally mount each of the vanes 19, wherein each of the vanes 19 includes a panel outer pivot axle 30 mounted to each vane 19, in a manner as illustrated in the FIG. 1 for example, orthogonally intersecting an outer periphery of the front and rear plates 12 and 14 permitting pivotment of each vane 19. Each of the outer pivot axles 30 are arranged parallel relative to one another. A panel inner axle 31 is directed through an inner edge of each vane 19 and is received within an arcuate slot 32 whose radius of curvature is coincident with the outer pivot axle 30 to permit pivotment of each vane about each outer pivot axle 30. A fastener 33 mounted to each inner axle 31 exteriorly of the rear plate 14 permits selective securement of each inner axle 31 relative to each slot to permit effective changing of pitch of each vane relative to the central cone 18.
The FIG. 10 illustrates the use of a plurality of arcuate liquid chambers 34 mounted to the forward surface of the front plate 12, wherein each liquid chamber 34 is spaced equally relative to an adjacent chamber, and includes a respective first and second fluid 35 and 36 of a respective first and second coloration and of a respective first and second specific gravity, wherein the first and second gravity is arranged to be greater than the second specific gravity to effect separation of the first and second liquid during periods of non-rotation of the housing 11. For example, the first fluid may be yellow and the second blue, whereupon rotation of the housing 11, the yellow and blue fluids will mix to provide for a resultant green coloration or third coloration. In this manner, the chambers 34 provide for rotation indicators of the housing to permit visual indication of rotation and energy generation produced by rotation of the housing 11.
As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
