IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 155,472, dated September 29, 1874; application filed

August 25, 1874.

To all whom it may concern:

Be it known that I, Peyton Smythe, of San Antonio, in the county of Bexar and State of Texas, have invented a new and valuable Improvement in Windmills; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a sectional view of my windmill. Fig. 2 is a sectional view of the same.

This invention has relation to self - regulating and self - adjusting wind - wheels for pumping water, and for all purposes where a wind-power can be made usefully available. The nature of my invention consists in hanging the wind-sails on arms radiating from a horizontal revolving shaft, which is free to turn with a vertical post, by securely attaching one end of each sail to one of the radial arms, and connecting the other ends of the sails to ropes.or chains which pass over pulleys, and are attached to a weight, whereby the speed of the. wheel will be diminished as the force of the wind increases, as will be fully understood from the following description.

In the annexed drawings, A designates the base of the mill, from which rises perpendicularly a post, B, that is free to turn about its axis. 0 designates a horizontal shaft, which has its bearings in the upper end of the post B, and which is free to turn about its axis. On this shaft 0 are two hubs, a a¹, an eccentric, I), and a large wheel, / which latter will serve as a balance or fly wheel, and equalize the movements of the mill.

The eccentric δ is embraced by a yoke, c, which is secured to the upper end of a rod, d, the lower end of which is connected, by a swivel, e, to a rod, d', for actuating a pump or other machine. Both rods d d' are free to play up and down inside of the hollow post B, and are so moved by the rotation of the shaft 0.

N N designate a number of wind-sails, which are permanently secured to rods n, radiating from the hub a, and connected by their other ends to a slide, G, having endwise movement inside of the hollow shaft G.

The connections of the sails N to slide G are made by means of ropes r, which are passed through ring-pulleys j, attached to. the outer ends of arms fc radiating from the hub a¹ on the outer end of the shaft C. All of the ropes or chains r are carried into the shaft G, and attached to the slide G. The slide Gis connected toaflat chain,g, by means of a swivel, i, which prevents this chain from being twisted when shaft 0 is rotated. The chain g passes around the middle one of three connected pulleys, E, having their bearings in the upper end of a bracket, D, fixed to the post B.

W designates a weight, which is hung, by means of a chain, from one of the pulleys E; and h designates a pull - cord, which is wound around the other one of the pulleys E in such manner that, by pulling on it, the chain g will be unwound from its pulley, and the weight-chain will be wound up.

Weight W should be sufficiently heavy to hold the sails N extended during a light wind, and, as the wind increases, this weight will be raised by the pressure on the sails, and allow them to take less wind.

By means of the rope h the sails can be held up to the wind however violent it may blow.
