IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No. Ϊ 75.355, dated March 28, 1876; application filed September 2, 1875.

To all whom it may concern:

Be it known that I, Walter King, of Rich™.⁰^’^{iu the} county of Ray and in the State oi Missouri, have invented certain new and useful Improvements in Wind-Wheels; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, 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 windwheel, as will be hereinafter more fully set forth.

In order to enable others skilled in the ait 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, which represents a perspective view of my wind-wheel.

A represents the frame-work of my windwheel, in which is the vertical shaft B. On the upper end of this shaft are two heads, 0 C, set at right angles with each other and detachably connected to the shaft. Longitudinally through the upper portion of each head 0, at each end, is inserted a spindle, a, and in the lower part of the head, at each end, is a projecting stop, b, for the wing placed on the spindles. By such means the shaft B can be lifted off, and the heads removed for transportation, and it is, moreover, very strong and durable.

The stops b may be constructed of a springboard attached to and projecting from the head in such a manner as to stop the wing in a perpendicular position on the outer end of the spring-stop cl, against which the wing strikes. This spring and cushion are intended to prevent too much noise and violence in the shifting of the wings in the wind, and also to enable the wing to sway back in an elastic manner before very high winds; but, in place of a springstop, a solid cushioned stop will be found sufficient in most cases.

On the head at each end is also attached a stop, e, which prevents the wings from passing the horizontal. The wing is composed of an end piece, D, from which extends a tapered rib, E, of sufficient strength and depth to carry elastic slats G G, secured to the rib and left | free at their lower ends. These slats may be made of wood, steel, or other material. The wing thus constructed is poised or balanced in both its length and its breadth on the point or tip of the spindle a, leaving but a small surface of broadside above the line of the spindle as compared to the surface below, and leaving a little excess of weight in the part below the spindle, so that the wing in a calm may incline down at an angle of about fortyfive degrees. On such a wing so poised the wind blowing on the one side will bring the broadside perpendicular, and on the opposite side will bring the same to a horizontal position, and thus, by using any number of wings greater than two, rotation of the main shaft is effected.

The two wings attached to one head may be connected by a bent rod, h, so that each wing will assist the other in the quarter-circle shift which each makes in action in the wind.

By means of cords i, passing from the tops of the wings down to the attendant below, he may lift aud hold (by fastening on the main shaft) any or all of *the wings in a horizontal position, and thus stop the wheel, or apply only a part of them for work, according to the wind or work.

The operator may also so slack up the cords as to permit the wings to descend only to the extent of presenting any given amount of broadside, and so graduate the wings to the wind and work.

By using an elastic cord, or one having a spring introduced at any part in its length, and removing the stops on the heads, the wings may be made to depend altogether upon the elasticity of the cord for the amount of wind required to throw them out of the wind.

It will be noticed that all the wings act independent of each other, so that they may all be placed in a horizontal position at one time, and thus get out of the wind, while, if opposite wings are fixed rigidly upon a turning shaft, then only one-half the wings can be placed out of the wind.

If the wings are fixed rigidty together by a rod, as at h, then, by means of a cord attached to the foot of one of them, or to the connection between the two, the foot may be drawn rigidly to the stop, and then a wheel of four

175,355 such wings can be made to ⁱ⁽lay to,” or stop, in the wind.
