WINDMILL.

SPECIFICATION forming part of Letters Patent No. 352,108, dated November 9, 1886.

Application filed April 1, 1886. Serial No. 197.424. (No model) To all whom it may concern.-

Be it known thatI, FRED A. BAKER, a citizen of the United States, residing at Roan n, in the county of Wabash and State of Indiana,

have invented certain new and useful -Im provements in Windmills, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to improvements in windmills; and it consists in the novel construction and arrangement of devices, as will be hereinafter fully explained, and particularly pointed out in the appended claims.

The annexed drawings,to which reference is 1 made, fully illustrate my invention, in which Figure 1 represents a vertical sectional view of my device. Fig. 2 is a horizontal sectional view taken on line a: m, Fig. 1. Fig. 3 isa top view with the wheel removed. Fig. 4is a detail view of a section of thewheel.

Referring by letter to the accompanying drawings, A designates the tubular support for the operating mechanism which extends through a central opening in the platform of 5 the tower B, and is braced by rods at, having adjusting turn-buckles 1), whereby the windwheel may be leveled at will. This tubular support is provided at its upper end with a circular flanged bearing, a, and a collar, d, be-

0 low the same.

Above the flanged tubular portion extends a tubular bearing, 0, on which is mounted a casting, 0,-having at its lower end a circular flange, f, and a roller, 9, which travels upon the circular flange of the lower tubular portion. This casting O is provided with two arms,h andi, the former extending rearwardly and the latter laterally, to each of which are connected cords or chains kit, that pass around pulleys ll, journaled in brackets on the vane D, thence over pulleys m, journaled in a bracket, n, on thetop of the frame of the vane. This frame 1) of the vane is provided with bearingsr r, which connect theframe and its vane with the vertical tubular bearings aforesaid. The cords or chains pass down through the tn. bular bearings to a governor near the ground, which will be further described. From this tubular casting 0 projects 'forwardly a tapering bearing armor axle for the wheel, and upon which the latterrevolves. This wheel conthe Vertical rod g, which extends near the ground for operating machinery, drawing water, 850.

The casting above referred to is further pro- -vided with two rods, 2 e, which extend laterally therefrom and parallel with the wheel,and at the outer ends of these rods is secured a vane, G, which projects beyond the wheel and serves as rudder to said wheel when the latter is out of the wind and keeps it in line therewith, thus preventing said wheel from revolving when out of gear.

One of the cords, is, secured to the rear arm of the casting O, is secured at its lower end to a weight, H, which has a central vertical tube, l,through which passes the lower end of the other cord, chain, or wire, k, the end of which is swiveled to a handlever, J, which is pivotedat oneend tothetower-frame. This weight serves as a governor, and can be increased, if desired, byapplying additional weights to it, and when it is desired to throw the wheel out of the wind the operator simply bears upon the hand-lever, thus drawing the cord or wire 70, and causing the casting with its wheel to turn and the wheel to assume a parallel position to the main vane. Similar action is ob tained by the weighted governor under heavy winds, and the weight causes the wheel to again face the wind after a gale.

It will be seen that the axle or bearing for the wheel-hub,being tapering from the casting O to the end thereof, and being larger near the gear-wheel, tends to force .the wheel against the wind, thus relieving the end shaft or tubular bearing from heavy pressure, and by arranging the wheel nearer to the center,as shown in the drawings,the wheel can be more quickly adjusted to the wind and has not a great distance to travel in getting inand out of the wind, and at the same time gives a uniform motion, and the rims being made of galvanized iron, with iron or wood blades secured to the wheel with the oblique portion, presents a durable wheel, and one that will not decay, as is the case with the rims made heretofore with mortises or slots to receive the blades, which cutting also weakens the rims; and it will be further observed that the anti-friction roller on the casting O, traveling on the turn-table or flanged tubular bearing, receives the weight of said casting and wheel and permits both to shift in and out of the wind with ease, and that the casting and vane are independent of one another in action thus permitting the casting and wheel upon it to turn with perfect freedom and ease upon the turn-table, and that the vane is always held in line with the wind, while the wheel does the shifting or turning out of the wind. At the same ti meit is durable, not liable to get out of order, and not expensive to manufacture. Should a geanwheel break, the broken section could be readily replaced with a new section.

Having described my invention, what I claim, and desire to secure by Letters Patent, 15-

1. The combination, in a windmill, of the tower B, the tubular portion A, braced and flanged, as described, the flanged tubular easting 0, bearing the arms h i and the axle of the wind-wheel, and also a roller, the cords 7c is, leading from the said arms around pulleys on the vane D, over pulleys m on the frame of this vane, and attached to a weight, H, and lever J, the gearing which transmits rotation from the wind-wheel to the tubular shaft y, and the gearing at the lower end of this shaft, all as shown and described.

2. The combination, with the tower B, of the main tubular support A, flanged atd a, and also flanged near its lower end, the braces therefor provided with turn-buckles, the tubular casting O, armed as described and carrying a wheel which bearson flange c,thevaneframe journaled on the tube A, and a bracket supported upon an upper extension of the vane-fran1e and bearing pulleys for the ropes 70 70, all constructed and adapted to operate substantially in the manner and for the purposes described.

In testimony whereof I affix my signature in presence of two witnesses.

FRED A. BAKER.
