ELLWOOD OLEAVEB, OF HAWTHORNE, IOWA.

IMPROVEMENT IN WIND-POWERS.

Specification forming part of Letters Patent No. 175,032, datd March 21, 1876; application filed To all whom it may concern:

Be it known that I, ELLWOOD GLEAVER, of Hawthorne, in the county of Montgomery and State of Iowa, have invented a new and 1mproved Wind-Power; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to certain improvements upon wind-powers, generally known as wind-wheels.

Said improvements will be first described in connection with all that is necessary to a full understanding thereof, and then clearly pointed out in the claims.

Figure 1 is a vertical section of my improved wind-power, and Fig. 2 is a plan view.

Similar letters of reference indicate corresponding parts.

A isa vertical shaft. This supports on its upper end four long flat bars or arms, B, horizontally and at right angles to each other. These arms should not be less than one-third the width of the vanes D, and, when 'made of wood, will be strengthened by the short additional arms 0 bolted thereon, on which is attached the pyramidical frame T, supporting the brace-rods U, which are attached to the arms 0 by the carriers V.

The vanes D are hinged in pairs to the arms B on the forward or advancing edge, there being an upper and a lower vane to each pair. The hinges F being raised a short distance from the arm by the blocks E gives an open space for the passage of air when the vanes are closed, and by placing the hinges on the vanes at a distance from the edge equal to the thickness ofthe blocks E, this space is nearly or quite closed when the vanes are opened to receive the force of the wind.

Each pair of vanes being made of similar size and weight, they will exactly balance each other by means of the balance-lever G,

working on a bolt passing through the center thereof, and which serves to attach it to the arm B, each vane being attached to the balance-lever by the links H. The vanes being thus perfectly balanced, it will be seen that a very light wind is sufiieient to close them when the forward edge approaches the wind January 22, 1876.

in turning, and when the opposite or rear edge is exposed and receding from the wind a similar motion will open them to their full extent, which is regulated by the check I,

which is attached to and made a part of the lever G, to which is also attached the arm K. From the end of said arm K a rod, L, extends to the rocking lever M, and from the other end of said lever M a rod, N, reaches down and passes through the regulating-plate O, which is held in place by the yoke P. The lower ends of the rods N are provided with a hook or ring, which prevents them from drawing through the plate 0 when the said plate is drawn down by the stop-plate R.

For the purpose of stopping the power when wanted, the stop-plate R, working on top of the regulating-plate O, and connected by the draw-rod S with the weighted lever W, and the cord Y, is used by pulling on the cord, which draws down the regulating-plate, and, consequently, the rods N, which, closing the vanes, produces the efi'ect desired. 0n releasing the cord, the weight on the end of the lever W elevates the regulating-plate 0 back to its former position, when the vanes Will again open to the wind; the stop-plate R having lugs or hooked bolts X on the under side, which, working through and under the regulating-plate, keeps both plates together and in position, the whole arrangement being simple and effective.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of the arms B, the vanes D, the balance-lever G, and the liuks'H, all substantially as specified.

2. The combination of the lever G and arm K, the rod L, the rocking lever M, and the rod N, all substantially as specified.

3. The combination of the yoke P, the regulating-plate O, the stop-plate R, the draw-rods S, the weighted lever W, and the cord Y, all substantially as specified.

The above specification of my invention signed by me this 1st day of December, 187 5.
