HARVEY PAGKER, OF SANDWICH, ILLINOIS.

IMPROVEMENT IN WINDMILLS.

Specication forming part of Letters Patent No. 178.664, dated June 13, 1876; application filed March 16, i876.

To all whom zt-may concern Be it known that I, HARVEY PACKER, ot' Sandwich, De Kalb county, State ot' Illinois, have invented new and useful Improvements in lVindmills, of which the following is a full description, reference being had to the accom'- panying drawings, in which- Figurevl is a rear elevation, partly in section; Fig. 2, a top or plan View; and Fig. 3, a detail of the vane-coupling.

The object of this invention is to so construct a windmill. that it will start out of the wind easily and readily, so that the weights` will allow the head to move toward the vane steadil)T without jerking or moving harder in some places than in others, and so any sagging of the vane can be taken up and the parts be kept in proper line.

In the drawings, A represents the base or frame work; B, its cap or top plate; (l, a revolving band or bearing; D, hollow gudg'eon D', gudgeonbox, with a hole through the center; E, hollow revolving shaft or box; E', metal eup of revolving box F F', tin or projecting side of the shaft or box E; G G', an L-lever; H, side arm or shaft; I J, rods supporting balls; K, rod for operatin r the L or bell-crank lever G; L, vane; M, vane shaft or bar; N, chain or cord for limiting the movement of the vane; O, wind-wheel; a b, arms on the head E' for supporting the vane; c, adjustable upper bearing for the vane-shaft; 'd d', nuts for adjusting the bearing' c e, vane shaft; fj", pulley wheels, over which a cord passes for throwing and holding the wheel O out of the wind; g, castings for holding' the` anti-friction bearing-wheels h 'i j k, balls; l, shaft ot' wind-wheel; m, bearing for Windwheel shaft.

The frame A, which constitutes the supporting-base, is lnade and braced in any suitable form, and is made ot' any desired height.

The top B of this frame may be made of wood or metal, and it is provided with a eentralopening sufficiently large to permit the Immediately above this head or cap B, the box-shaft E is provided with a circular collar or bearingband,l c, which, when the box is square, is The anti-friction wheels 7L bear against this collar, and thereby hold the box-shaft in a vertical position. The box-shaft is provided with a metal head or top, E', to which the shaft or arm H is attached, through the bearing m of the wind-wheel, and the arms a b ofthe vane hinge. The bar or arm H extends out to a line or nearly to a line'with the inner end ofthe vane L. On the outer end of this bar, the bent bar or bell-crank leverG' varrangement of the bar or arm H, rod K,and

the vane with thearm G, gives an increasing' leverage. As the balls rise and the leverage increases, the ball comes into play .and increases the weight so that there is no jerking or jarring in the movement. The balls are connected together by chains, as shown, and the ball t', having its rod G' made in one piece with the lever G, moves at all times when there is any deiiection ot' the vane. The boxshat't E is most conveniently made of four boards of equal width, and a pump or other shaft passes down through its center and through the gudgeon D and the gudgeon box or bearing D. with a crank or gearing (not shown) on the inner end of the shaft l of the wind-wheel. A thin board or tin,F F', is attached to the back of the b ox-shat't, as shown.

rIhe lower section F may be omitted by making the upper one, F', a little Wider; but I prefer to make it as shown, as the long narrow fin is out of' the Way, and in operation it at irst takes the full strength ofthe wind, but, as it turns, the box makes it take less wind, and, after turning about one-quarter of the way around, the wind is so far deiieeted as not to eii'ect it. Its object and purpose is to start the wheel out of line with the vane, and after the wheel is started its rotation will carrjr it out of any strong wind. It also, with the balls, acts as a regulator to equalize the work ot' the wheel. The chain N prevents the vane from passing too far in the Wrong direc- Ihis central rod is connected tion. Hinged vanes, as they Wear, are liable to sag, and not only become unsightly, but also interfere with the working of the balls, and so as to bind and Work hard. To avoid or regulate this, theupper part c of the hinge is made adjustable. It passes through the fixed arm b, and is held by the nuts d d. In order to take up any sag, unscreW theV nut d and screw up the nut d until the vane is raised to position; then tighten the nut d. The Wheel O is made and attached to its shaft Z in any of the Well-known Ways.

What I claim as new, and desire to secure by Letters Patent, is,-

1. The long narrow side vane of fm F F',
