ASAHEL D. RUDDOGK, 0F BERLIN, WISCONSIN, ASSIGNOR OF ONE-HALF HIS RIGHT TO T. L. TERRY, OF SAME PLACE.

IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 120,778, dated November 7, 1871.

To all whom it ma/y concern:

Be it known that I, AsAHEL D. RUDDOGK, of Berlin, in the county of Green Lake, and in the State of Wisconsin, have invented certain new and useful Improvements in Wind mill; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a windmill, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use thev same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a side view of my windmill. Fig. 2. is an inside view `of the wheel with fans or wings; and Fig. 3 is a section of the wheel, showing the mode of pivoting and operating the wings or fans.

A represents a post running from the building or ground, and having upon its upper end a bed, B, to form a rest for the turn-table. C is the turn-table, having on one side a horizontal beam, D, to which the vane or wind-board E is attached. On the other side of the turn table are suitable bearings for a horizontal shaft, a, upon the outer end of which the wheel containing the fans or wings is placed. This wheel is composed of a hub, b, radial arms d d, an inner circle, e, let into said arms, and an outer circle, f, attached to the outer ends of the arms. G G are the fans or wings pivoted to the wheel in the following manner: Near one edge, at the inner end of each fan, is a pin, z', which is passed through a hole in the inner circle e, and upon the edge of the fan a suitable distance from the outer end is an angular pin, h, which is passed from the inside through a hole in the outer circle f, thus pivoting each fan upon its edge, as shown in Fig. 3. The outer edges of the fans G G are all connected by links or rods 7c lc, and at least one fan in the series between each set of arms d is provided with an eye or loop, Z. ed the outer bent end of a'rod, m, the inner In each of the eyes or loops l is insertend of which passes into the hub b and is allowed to turn in the same. Each rod m is, by a crank, n, connected with a collar, H, which slides upon the shaft c, said crank being flrmly attached to the rod and pivoted to the collar. I is a lever pivoted to one of the standards on the turntable, and its outer end working in the sliding collar H, while the other end is, by a rod, p, which passes downward, connected with a weight, J, land float K. The rod p passes through a hollow shaft, L, which connects at the upper end with the shaft a by bevel-cog gearing, as shown, or by a crank or other suit able means. The machinery to be driven is connected with the lower end of said shaft by any suitable means. M is the governor-lever,

provided with a vane or fan, N, and attached to a pivoted lever, s, said pivoted lever s being connected at one end with the inner end of the lever I, and at the other end provided with a weight, t, to hold the governor in position. The governor is a lever, M, connecting the lever I with a vane or fan, N, placed flatwise to the wind. When the wind blows hard this vane is depressed, by which the end of the lever I is raised. This pulls back the sliding collar H and turns the wings G G out of the wind. The weight J operates against the governor, and by so much holds the wheel steadily in the wind. The float K rests in the water-tank, and is only used in a pumping-mill. When thc tank ills with water, the iioat raises the weight J, which permits the governor to pull the wings out of the wind and the mill stops.

In place of the cranks n n for turning the wings I may use a simple gear on some-sized mills, and therefore do not wish to confine my self specifically to said cranks.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The fans or wings G G, provided with pins ih, as described, so as to be pivoted on their edges to the wheel b d e, and operated by means of the sliding collar H, cranks n n, rods m m, and eyes or loops Z Z, all substantially as and for the purposes herein set forth.

2. The combination of the hollow shaft L and the governing-rod p with weight J and iioat K,

all constructed and operating substantially as have hereunto set my hand this 22d day of June, and for the purposes herein set forth. 1871.

3. The combination of the governor M N, le- ASAHEL D. RUDDOGK. Ver s, and Weight t, all constructed and arranged substantially as and for the purposes herein set Witnesses: forth.

In testimony that I claim the foregoing I N. JOHNSON. (118)
