Claims.
This invention appertains to new and useful improvements in wind motors and more particularly to a wind operated wheel. The present invention is a division of my co-pending application Serial No. 159,961, filed August 19, 1937.
The principal object of the present invention is to provide a windmill wheel in which the vanes are constructed in such a manner that they can be easily set for efficient operation.
Another important object of the invention is to provide a windmill wheel in which the vanes are constructed and arranged in such a manner that they can be repaired and replaced conveniently.
These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.
In the drawings:
Figure l is a diametrically disposed sectional view.
Figure 2 is a fragmentary front elevational view.
Figure 3 is a front elevational view of one of the vanes units.
Figure 4 is a fragmentary side elevational View partly in section of the tie means.
Referring to the drawings wherein like numerals designate like parts, it can be seen that the blade units can be stamped from sheet metal, the outer units being arranged on the squared head portion 4 1 of the shaft 32, while the inner units are arranged on the polygonal portion 43 of the shaft, The hubs 41 of the inner group of units are banked against the shoulder 58 of the shaft by jam nuts 5! on the threaded portion 46, while the hubs of the outer group are banked against the shoulder 52 by a jam nut or nuts 53 on the threaded portion 45,
As is clearly shown in Figure 3, each vane unit consists of the hub 41 and the pair of radially disposed and properly pitched blades 4949, and each hub 47 is formed with a square opening 48 for receiving the corresponding squared portion 43 or 64 of the shaft '52.
The blades of the inner and outer groups are brought into interlapping relation as suggested in Figure 2 as well as in Figure 1 and held in this manner by a tie rod or wires 54 trained through openings 55 in the blade. These tie 'members are preferably in section and each section has its end portions threaded as at 54a for reception by the right and left internally threaded turnbuckle barrel 5%.
In conjunction with the shaft 50 a suitable brake A can be employed and this, of course, includes the brake shoe B.
While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the claimed as new is:
1. A wind wheel comprising a shaft having a pair of longitudinally spaced polygonal portions, a pair of. vanes assemblies, each of these said vanes assemblies consisting of a plurality of hub plates each having a polygonal opening receiving a polygonal portion of the shaft and each of the hub plates provided with radially disposed blades, the blades of one assembly being disposed in interlapping relation with the blades of the other assembly, the outer portions of the blades being formed with openings and an elongated tie element disposed through the openings of the interlapping blades.
2. A wind wheel comprising a shaft having polygonal formations thereon, a pair of vanes assemblies on the shaft, each of the vanes assemblies including a plurality of blade units, each of the said blade units being formed with polygonal-shaped openings to receive the corresponding polygonal formations of the shaft, the blades of one vanes assembly being disposed in interlapping relation with the blades-of the other vanes assembly, and tie means between the outer ends of the blades.
3. A wind wheel comprising a shaft having polygonal formations thereon, a pair of vanes assemblies on the shaft, each of the vanes assemblies including a plurality of blade units, each of the said blade units being formed with polygonal-shaped openings to receive the corresponding polygonal formations of the shaft, the blades of one vanes assembly being disposed in interlapping relation with the blades of the other vanes assembly, and tie means between the outer ends of the blades, the blades unit of each assembly being arranged in banked relation at their inner ends, said assemblies being spaced apart on the shaft.
4. In a windmill wheel, a vane unit,'said unit consisting of a hub forming plate, and a pair of blades extending therefrom in opposite directions the lead edge of one blade being on a line diametrically through the hub forming plate with the tail edge of the other blade.
5. A windmill wheel comprising a shaft havinvention, what is ing a polygonal portion, a reduced polygonal extension at one end of the shaft, the portion of the shaft between the polygonal extension in the said polygonal portion being provided with threads, said shaft being formed with a shoulder at the end of the polygonal portion remote from the threaded portion of the shaft, a shoulder at the point Where the reduced polygonal extension merges with the threaded portion, a
10 pair of vanes assemblies each including a hub,
one of the hubs being adapted to receive the polygonal portion of the shaft and to abut the shoulder adjacent thereto, the other hub being adapted to receive the polygonal extension and to abut the shoulder adjacent thereto, a retaining element on the free end portion of the polygonal extension, and a nut on the threaded portion of the shaft to hold the other hub on the polygonal portion of the shaft.
