WINDMILL.

SPECIFICATION forming part of Letters Patent No. 291,783, dated January 8, 1884,

Application filed February 3, 1883.

(No model.)

Toall whom it may concern.-

Be it known that I, ELI J. SorinooK, a citizen of the United States of America, residing at Goshen, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Vindmills, of which the following is a specification.

This invention relates to windmills; and it consists in the peculiar construction and arrangement of the same, whereby the wheel and vane may be thrown out of line, and a brake applied to the wheel to keep it sta tionary, substantially as will be hereinafter more fully set forth, and pointed out in the claims.

In order to enable others skilled in the art 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 invention.

A represents the wheel composed of a flanged or socketed central hub, a, in which are secured the radial arms a. To these arms are secured, by clips a and castings (6, two concentric rings, 1) b, in which are secured the wings or sails b of the wheel. The socketed hub a is, upon its rear side, formed or provided with a ring, 0, the purpose of which will be presently seen. This wheel A is mounted upon a shaft or axle, c, journaled in one side of the turn-table or swiveled head B.

B represents a large casting forming the turn-table or head of the mill, and is formed with a hollow neck, B", swiveled upon the tower or frame 0, as seen in the drawing. This head B is also provided with an opening, (1, in its center, in which, secured upon the inner end of the shaft 0, is a disk, 0*, provided with a wrist-pin connected by a pitman, 0, with the pump-rod D, reciprocating vertically through the hollow neck B. This rod D is formed with a doublebend, d, as seen in the drawing.

Upon the rear side of the head B are cast two lugs, c e, to which are pivoted the arms E E. Supporting the vane, and at right angles with these lugs, near the lower end of the head, are cast lugs e c, in which is journaled a rod, f, having its inner end bent, as seen atf, to bear against the ring 0, upon the wheel when the rod is turned, and so form a brake.

Near the outer end of the rod is secured an arm, F, provided with a weight, f and the extreme outer end of the rod is bent up, as seen at f, and formed with an eye, connected by a link, 9, to the arms E of the vane.

To the weighted arm F is also secured a cord, h, running over a pulley, h, in the head, and thence to the ground or to any point desired.

In operation, the parts of the mill are normally in the position shown by the drawing, and the head with its wheel and vane turns freely upon the tower with variations of the wind.

WVhen it is desired to stop the mill, the cord h is pulled, raising the arm F and turning the rod f, which, by its connecting-link, turns the vane and throws the wheel out of the wind. At the same time the cranked arm f, at the opposite end of the rod, bears against .the ring 0 upon the wheel, and effectually brakes it.

I am aware that it is not new to provide a windmill with a brake-ring to engage with a brake, and do not claim the same, broadly but hat I do claim, and desire to secure by Letters Patent, isr 1. In a windmill, the wheel A, provided with a ring, 0, and pivoted to the head or turn-table B, in combination with a crankrod, f, journaled in lugs e e, and formed with a brake at one end, adapted to engage with the ring 0, and leaving its extreme outer end bent up, as seen at f, and formed with an eye connected to the vane, whereby when the rod is turned the wheel is thrown out of In testimony whereof I affix my signature in presence of two Witnesses.

ELI J. SGI-IROCK.

rodf, formed with a brake, f, on one end, and connected by the link 9 with the vane E, the weighted arm F, rigidly secured to the brake-rod, and the operating-cord h, and I pulley h, all constructed and arranged to oplVitnesses:
