TRANSMISSION MECHANISM FOR WINDMILLS.
Specification of Letters Patent.
.Application filed June 8, 1910. Serial No. 565,896.
To all whom it may concern:
' Be it known that I, SIMMoNs HARRELL, a
citizen of the United States, residing at carried by the revoluble shaft of the windmill, and designed toperform a cam action, whereby thepump rod may be vertically reciprocated. Ithas been found that by making this inclined grooved wheel vertically adjustable upon the revoluble shaft of the windmill, the throw of the pump rod may be changed. To adjust the inclined grooved wheel, the bore thereof is provided with elongated strips or members, to be received by means upon the revoluble windmill shaft, in order to hold the inclined grooved wheel properly in position,
A further feature of the invention resides in the provision of novel wings or propeller blades having partial flanged or capped portions, by which and the peculiar shape of the wings or blades a great deal of power is transmitted to the revoluble shaft, for the reason that the air currents or wind are fully gathered, or received by the blades or wings.
In the exposition of this specification, a particular design of machine is adhered to,
, but the invention is not to be confined to this specific design. Its reduction to practice may require certain changes and alterations, which the right is claimed to make, provided such changes and alterations are comprehended by the appended claim.
In the drawings :Figure 1 is a side elevation of a windmill, constructed in accordance with the particular features of the invention. Fig. 2 is a side elevation of the lower portion of the windmill, showing the inclined grooved wheel in a position opposite to that shown in Fig. 1. Fig. 3 is a vertical sectional view through the lower portion of the windmill, illustrating the manner in which the inclined grooved wheel may be adjusted. Fig. et is a view similar to Fig. 3 showing the inclined wheel adjusted in a position different to that shown in Fig. 3. 1 As to the drawings, 1 denotes the frame "of the windmill, which is shown rectangular. The frame 1 comprises two parts ,2 and ,Patented Mar. 4., 1913.
3, the side portions 4 and the upper portion 5 from the rigid frame for the support of the upper end 6 of the shaft 1O (which is provided with a spindle 7) ,while the frame 3 .(which is provided with a sufficient amount of rigidity through the medium of the braces 8) supports the lower portion 9 of the revoluble shaft 10. The shaft 10 comprises two parts 11 and 12, which are coupled together, as shown at 13. The up per portion of the frame 3 supports the usual form of governor 14, whereby the speed of the shaft 10 may be governed. The part 11 is formed with a spindle 16, which is mounted in a bearing 17 of the lower portion 18 of the frame 2. The'part' 11 of the. shaft 10 is provided with an inclined grooved wheel 19, which is provided with elongated members 20 having slots 20 These elongated members 20 are received in the grooves 21 of the part 11 of the shaft. Screws 22 extend through the slots 20 of the members 20, and are threaded into the part 11 of the shaft, so as to slidably secure the members 20 in the grooves 21.
Heads 24: are carried-by the screws 22, in order to hold the inclined grooved wheel and its members QOinadjusted position.
25 designates the usual form of pump rod, which reciprocates in the bearings-26 and 27 of the frame 3. Projecting at right angles to the pump rod is a bifurcated lug 28 having an antifrictional member 29 to operate in the groove of the wheel 19. It will be evident that, as therevoluble shaft 10 rotates, the inclined wheel will operate the pump rod 25 vertically;
The upper portion ofthe shaft 10 is pro vided with a plurality of wings or blades i 30 which are so shaped or curved .as to exert agreat deal of power for the shaft 10, when the wind or air current strikes them. By the curvature or shape of the wings or blade, the blades opposite one another form a compoundorSshaped Wing or blade. Each wing or blade adjacent its outer portion and upon its upper and lower edges, is provided with flanges or caps 31,
which assist in exerting power for the shaft,
and also assist in holding the blast of air currents or wind in the curved portion of the blades. The blades are braced with re gard to the revoluble shaft by means of the tie rods 32.
The invention having been described, what is claimed as new and useful is 1- In combination; a frame having a thrust bearing in its base; a revoluble shaft having oppositely disposed elongated grooves, one upon each side of the shaft at its lower end portion, and mounted at its lower end in the thrust bearing; an inclined grooved wheel having an inclined bore, to receive the shaft, and provided with integral members having elongated slots, said members extending from the opposite faces of the grooved Wheel, and offset from one another to fitslidably longitudinally in the grooves of the shaft; and thumb screws passing through the slots of the members and threaded into the shaft, for holding the inclined wheel in adjusted positions; the inclined wheel constituting means adapted for operating a reciprocating element.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
SIMMONS HARRELL.
