WINDIVHLL.

SPECIFICATION forming part of Letters Patent No. 390,517, dated October 2, 1888.

Application filed November 1S, ISST. Scl-inl No. 255,516. (No model.)

To aZ whom t may concern:

Be it known that I, GUsTAvUs A.. RAAseH, of Higginsville, in the county of La Fayette and State of Missouri, have invented certain new and useful Improvements in W'indmills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in windmills; and it consists in the arrangement and combination of devices, which will be more fully described hereinafter, whereby an automatically regulating windmill is produced.

Figure I is a side elevation of a windmill embodying my invention, partly in section. Figs. 2 and 3 are detail views of the same.

A represents a portion of the frame-work which forms a bearing for the shaft B. In the top of this frame A is formed a suitable oil-well, C, in which the lubricant is placed, and in which the disks D, secured to the shaft B, revolve. As these disks revolve, they catch the oil in the well C and feed it to bearings E -upon each side of the disks, so as to keep the shaft constantly lubricated. Secured to the shaft is the hub F, which is curved backward over the shaft, as shown, and to which the vanes of the wheel are secured by means of the ring G, which is clamped to the hub F by suitable bolts in such a manner as to hold the inner ends of the vanes rigidly in position. Both the inn'er side of the vertical part of the hub F and the inner side of the ring G are made corrugated, so as to take a firm hold upon the vanes, and thus prevent any possibility of their working loose. The hub F is shaped, as shown, so as to bring the weight of the wheel back over the front bearing, and thus balance the Wheel in position, instead of securing the wheel to the end of the shaft in the usual manner.

To the inner end of the shaft B is secured the disk H, from which extends the wrist-pin, and upon this Wrist-pin is placed the frictionroller I. This frictionroller is held, as the disk H revolves, in the vertically moving frame J, which is provided with ilanges K, which catch over opposite sides of the edges of the wheel I, and thus prevent it from getting out of line with the frame or becoming displaced therefrom. This frame .I is composed of two parts which are bolted together and which must be separated before the frietion-roller can be removed. The dauges K upon the lower part of the frame J serve to hold a suitable quantity of oil, in which the roller I revolves, so as to keep the roller always lubricated and to cause it to work with as little friction as possible. This verticallymoving frame J is held between suitableguides formed upon the frame A, and to this frame the pitman is secured. Projecting at right angles to inner end of the frame A is the arm L, by means of which the frame A is swung around, so as to present the wheel either at au angle or with its edge to the wind.

The beam M, to which the vane is secured, is pivoted to the frame A, and mounted upon this beam M is the support N, upon which the weighted lever O is pivoted. The upper end of this lever O is provided with an eye, in which the operating wire, rope, or chain is fastened for the purpose of moving the wheel out of the wind. The weight P on the lower end of the lever O is vertically adjustable, so as to increase or decrease the amount of power which is required to remove the lever. Extending from this lever O is a connectingrod, Q, which has its front end fastened to the arm L, and by means of which the wheel is swung around, so as to present its edge to the wiud. Also fastened to this lever O is a connecting rod, R, which has its rear end fastened to the arm S, which projects at a suitable angle from the weighted lever T, which is provided with a vane, U, at its upper end and an adjustable weight, V, at its lower one. 'When the lever O has its upper end drawn downward by the wire or cord connected thereto, a pull is eX- erted upon the frame A, so as to swing the wheel around with its edge to the wind, and at the same time a push is exerted upon the lever T, so as to force it backward, as shown in dotted lines. In case ofa storm the pressure of the wind against the vane U forces the lever T backward, and then the rod R exerts IOO a Apull both upon the lever O -and the frame A', so as to swing the Wheel around. The two Weights V P serve to return the parts quickly to position as soon as they are left free to move either by the slackening of the cord or Wire or the lessening in the force of the wind.

Having thus described my invention, I claim- The combination of the frame A, provided with a projection, L, upon one side, the shrtft 3, journaled in the frame and having the Wind wheel secu red thereto, with the main frame M, pivoted to the frame A,thesupport N, mounted upon the beam, the Weighted lever O, journnled or pivoted upon the support, the Weighted :5 lever T, pivoted upon the beam and provided with the Vane U at its upper end and the arm S, the connecting-rod R, which connects the two Weighted levers together, and the rod Q, which connects the lever O with the projection zo L upon the frame, substantially as set forth.

In testimony whereof I affix my signature in presence of tWo Witnesses.
