Description
UNITED STATES PATENT QF IoE.
WILLIAM H. ALDRICH, on BELOIT, WISCONSIN.
IMPROVEMENT IN WINDMILL'S.
Spccification forming part of Letters Patent No. 165,292, dated Ju y 6, 1875;
application filed May 3, 1875.
To all whom it may concern:
Be it known that I, WILLIAM H. ALDRICH, of Beloit, in the county of Rock and in the State of Wisconsin, have invented certain new and useful Improvements in Windmills; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the aecompanyingdrawings, and to the letters of reference marked thereon, making a part of this specification.
The nature of my invention consists, first, in' a stationary regulating-vane located immediately in rear of the windwheel, to throw the Wheel wholly or partially out of the wind, according to the strength or force thereof second, in combining therewith a counterbalance, to throw the wheel in the wind again, as the force thereof decreases; third, in the combination of parts, all as hereinafter more fully set forth.
In order to enable others skilled in the art to which my invention appertains to make:
and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a perspective view of a windmill embodying my invention. Fig. 2 is a vertical section of the same. Fig. 3 is a perspective view of the stationary regulatingvane.
A represents the ordinary stand or framework of a windmill, provided with two hori- 'zontal plates, B and O, forming bearings for the wheel and vane-pivots. D represents the ordinary tail-vane attached to an arm formed on or attached to the upper end of a hollow or tubular pivot, E. Through this pivot passes the tubular pivot G of the wind-wheel H.
The lower end of the vane-pivot E forms a recess around the wheel-pivot, in which are placed a number of balls, a a, resting upon the lower horizontal plate 0. Near the upper end of the vane-pivot E is a circumferential groove, in which the upper horizontal plate B fits, said plate being bisected so as to be placed in said groove.
The wind-wheel H. may be constructed in any of the known and usual ways, and is made fastto a shaft, 1), which has its bearing in a tubular box, (1, projecting from a circular plate, I, provided with the tubular pivot G passing through the tubular vane-pivot E, as above stated.
The tubular vane-pivot E is formed with a cup-shaped recess at its top, and is provided with balls 1' in said recess, below which is a circumferential groove, around which the top plate Bis fitted. The plate I of the wheelpivot rests upon the balls i, and revolves on the same. The lower end of the vane-pivot E is also cup-shaped, and contains balls at, which are inclosed in the cup, and rest upon the. plate 0, thus making the movement of the parts perfectly free, and with little or no friction.
On the outer end of the box or bearing 01 is secured a rod or cross-bar, h, on each end of which are fastened a series of vertical blades, J J set at an angle, as shown, and forming a vane directly behind and opposite the central opening in the wind-wheel H.
The vane J being stationary, has the effect to throw the wheel H more or less out of the wind, according to the force of the same, and as the wheel is thrown back into the wind by a counter-balance, hereinafter described, the vane J will regulate the speed of the wheel.
At or near the inner end of the box or bearing d is attached an arm, m, connected by a link, it, with a crank-shaft, 1), having its bear ing in the arm of the tail-vane D, and on one arm of this crank-shaft is placed the counterbalancing weight L, for throwing the windwheel H into the wind again as the wind slacks.
The weight L is preferably made adjust-able on its arm, so as to regulate its counterbalancing effect according to the strength of the wind.
Having thus fully described my invention, what I claim as new, and desire to secure by. Letters Patent, is-- 1. In combination with a wind-wheel, a stationary regulating-vane, located directly behind and opposite the central opening of the wheel, for throwing the same more or less put of the wind, for the purposes herein set orth.
2. The combination with awind-wheel, of a with plate I, all constructed substantially as stationary regulating-vane, located immediand for the purposes herein set forth.
ately in rear of the wheel, and a connter-bal- In testimony that I claim the foregoing I ance connected with the Wheel, substantially have hereunto set my hand this 1st day of as and for the purposes herein set-forth. May, 1875.
3. The combination of the vane-pivot E, WILLIAM H ALDRIOH. having a central opening, made cup-shaped Witnesses: at the top and bottom, and inclosingballsi WILLIAM L. BRAMHALL,
and a, the plates B and (J, the wheel-pivot G, J. M. MASON.
