PEYTON SMYTHE, 01 SAN ANTONIO, TEXAS.

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 bad 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 windwheels 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, whlch is free to turn with a vertical post, by securely attaching one end of each sail to one of the radial arms, and connectingthe other ends of the sails to ropesor 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 per pendicularly a post, B, that is free to turn about its axis. 0 designates a horizontal shaft, which has its hearings 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 a, an eccentric, b, and a large wheel, f, which latter will serve as a balance or fly wheel, and equalize the movements of the mill.

The eccentric b is embraced by ayoke, 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 windsails, which are permanently secured to rods n, radiating from the hub a, and connected by their other ends to a slide, Gr, having endwise movement inside of the hollow shaft 0.

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 is radiating from the hub to on the outer end of the shaft 0. All

of the ropes or chains 1' are carried into the shaft (J, and attached to the slide Gr. The slide Gis connected to aflat chain, g, by means of a swivel, i, which prevents this chain from being twisted when shaft 0 is rotated. The chain 9 passes around the middle one of three connected pulleys, E, having their bearings in the upper end of a bracket, 1), 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 pullcord, which is wound around the otherone of the pulleys E in such manner that, by pulling on it, the chain 9 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 duringalight 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.

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

1. Sails N, secured to arms a radiating from revolving shaft 0, and having connected to their outer ends ropes or chains 1", which are passed through ring-pulleys j on arms k, and connected to a chain, g, passed around one of three connected pulleys, E, in combination with a weight, W, suspended from pulleys E, and pull-rope 71. attached to these pulleys, substantially as described.

2. The slide G and its swivel i, as means for connecting the sail ropes or chains r to the pulley-chain g, as set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

PEYTON SMYTHE.
