WIND-WHEEL.

SPECIFCATION forming part of Letters Patent No. 623,428, dated April 18, 1899.

Application led August 24, 1898. Serial No. 689,389. (No model.)

[o (LZ/f whom it nu@ concern,.-

Be it known that I, OBEN RUBARTS, of Newport, in the county of Lincoln and State of Oregon, have invented a new and Improved Wii1d-iVheel, of which the following is a full, clear, and exact description.

This invention relates to improvements in wind-wheels; and the object is to provide a wind-wheel of simple and comparatively light yet strong construction and having a simple means for adjusting the wheel-blades to the wind-pressure, thus providingv for a practically uniform speed of the wheel.

I will describe a wind-wheel embodying my invention and then point out the novel features in the appended claim.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional elevation of a windwheel embodying my invention. Fig. 2 is a plan view of a portion thereof. Fig. 3 is a plan view of a governor-rod employed, and Fig. e is a section on the line 4 et of Fig. 1.

Referring to the drawings1 designates a tubular tu rn-table base designed to besecured on the top of a tower of the usual construction. Mounted to rotate on the turn-table base 1 is a turn-table 2, the turn-table having a downwardly-extended iiange 3, engaging around the upper portion of the base 1, and having a raceway 4, in which bearingballs 5 are seated, and the upper portion of the base 1 is also provided with a raceway 6 to receive these balls. The balls maybe inserted through an opening 5 in the turn-table. The raceways e and 6 are shown as V- shaped, so that the walls thereof have but very little bearing upon the balls, and thus the friction is reduced to a minimum.

The vane-timber 7 is secured to a rearwardly-extended arm 8 on the turn-table, and on the forwardly-extended arm 9 of the turntable are mounted bearing-blocks 10 1l for the wheel-shaft 12. To the inner end of the wheel-shaft 12 a crank 13 is affixed, and engaging with the wrist-pin thereon is a pitman 14, which extends downward through the tubular base 1, and of course extends through the tower to a connection with the machine to be driven. To the outer end of the shaft 12 is secured the wheel-hub 15, and radiating from this wheel-hub are spokes or blade-rods 16, upon which the blades 17 are mounted to Swing.

Mounted on the shaft 12 and adapted to move longitudinally thereof and also to have a slight rotary movement relatively thereto is a governor-disk 18, having forwardly-extended lngs 19, provided with holes, through which 'ngers 2O on the blades 17 loosely extend. The governor-disk 18 is arranged forward of the bearing-block 10, and its hub portion is provided with an annular channel, in which fingers 21 of the governor-rod 22 eX- tend. This governor-rod is shown in the form of a plate and is mounted to slide on the top of the arm 3, the bearing-blocks lO and 11 being provided with openings, through which the governor-rod passes. The inner end of the governor-rod projects over the base 1, and it is provided with an opening 23, from one end wall of which a chain 2e extends and passes over a pulley 25, mounted in hangers attached to the turn-table. From the opposite end wall of the opening 23 a chain 26 extends overthepulley2. Abalancing-weight 27 is employed, which may be attached to either of the chains. As shown, the weight is attached to the chain 2G. At a suitable point in the length of the chain 24 is inter* posed a spring 28, designed to relieve the wheel from sudden shocks should a high gust of wind occur.

In operation when it is desired to stop the mill the weight 27 is to be placed on the chain 26, as shown in the drawings. The effect of the weight in this position will be to draw the governor-rod inwardly and cause the blades to stand parallel with the shaft, presenting only the edges of the blades and the arms of the wheel to the wind, as indicated in Fig. 1. face presented to the wind it is obvious that the wheel will remain stationary. When the wheel is to be put in motion, the weight 27 is to be hung on the chain 24, so that the weight will draw the rod 22 outward and cause the `olades to present an angle or rotating windsurface, according to the amount of weight placed on the chain. If the wind-pressure Therefore as there is no wind-sur- IOO increases, the blades will swing back and present less surface. This movement of the blades will of course draw the weight 27 npward. Vhen the wind-pressure decreases, the weight will again draw the rod 22 outward to cause the blades to present a greater surface to the wind. When the speed or power transmitted to the machine by the wind-wheel is to be increased or decreased, the operator will increase or diminish the weight until the desired power or speed is obtained.

It will be seen that by the use of the governor devices shown and described the windwheel is under perfect control at alltimes and that any desired amount of speed or power can be obtained in all the different changes of wind-pressure up to its greatest capacity. As the blades 17 have but a very little movement on their axes/they will adjust themselves instantly without affecting the rotary motion of the wind-wheel. If any sudden gust of wind should strike the wind-wheel, the spring 28 will prevent any sudden jerk on the wheel.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent- In a wind-wheel, a turn-table, arms extended in opposite directions from said turn-table, a vane mounted on one of said arms, a shaft mounted in bearings on the other of said arms, a hub fixed to the outer end of the shaft, blades having axial movement on said hub, a governor-disk mounted to slide on the shaft, connections between the blades and disk, a governor-rod having connection with the disk and mounted to slide on the arm supporting the shaft, a pulley supported on the turntable, a chain extended over they pulley and connecting with the rod forward of the pulley, a chain extended over said pulley and connecting with the rod rearward of the pulley, a spring in the last-named chain,and a weight adapted for connection with either of the chains, substantially as specified.
