IMPROVEMENT IN WINDNIILLS.

Specification forming part of Letters Patent No. 179,333, dated June 27, 1876; application led May 13, 1876.

To all whom it may concern:

Be it known that I, CHRISTIAN H. MILLER, of Northville, in the county of La Salle and in the State of Illinois, have invented certain new and useful Improvements in Windmills; 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 certain improvements on windmills, as will be hereinafter more fully set forth.

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, in which- Figure l is a perspective view of the windmill, and Fig. 2 is a detailed section of a part thereof.

A represents the main frame pivoted horizontally on the pipe'B, which is to be secured to a mast or tower in any convenient manner. D and E are the hinges of the rudder F, which loosely embrace the pipe, one at the top and the other at the bottom ofthe main frame, thus pivoting the rudder horizontally for the purpose of directing the mill, and the hinges having their pivotal point on the same vertical line as the pivotal point of the mill. The upper portion of the main frame A, forms two uprights. In the front uprightis the shaft K, upon which the wind-wheel is secured. Upon the rear upright of the main frame is rigidly secured the side vane G, on a horizontal line with the center of the wind-wheel, and in rear of and extending on both sides of the pivotal point of the mill. This side vane has at its end nearest the frame, a rod, H, the upper end of which is pivoted to the vane so as to turn in any direction, and its lower end is pivoted in the same manner to a rod, I, near the center thereof. The upper end of the rod I is pivoted in a like manner to the rudder F, and has at its lower end the weight J. A heavy wind pressing against the side vane tends to swing it, and the wind-wheel around parallel with the rudder, and the weight, by the operation of the rods, tends to return it to its natural position. The weight is intended to be moved along the rod I, to vary the sensitiveness of the mill to the wind.

To stop the mill, the cord L is provided, as shown, by which the operator on the ground can bring the side of the rudder parallel with the side of the wind-wheel.

Having thus fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is-

l. The side vane G, rigidly secured to the frame on a horizontal line with the center of the wind-wheel, when the said side vane shall be in rear of and extend onlboth sides of the pivotal point of the mill, substantially as herein set forth.l

2. The combination of the rudder F, provided with hinges D E, the hollow post B, provided with a shoulder on which rests the hinge E, and thepframe A, provided with a shoulder upon which rests the hinge D, all substantially as and for the purposes herein set forth.

3. The combination of the rudder F, the stationary vane-arm G, andthe rod I, pivoted to the rudder, provided with the weight J, and connected to the vane-arm by the rod H, all substantially as and for the purposes here-in set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 31st day of March, 1876.
