WINDMILL..

SPECIFICATION forming part of Letters Patent No. 375,245, dated December 20, 1887. Application iiled May 28, 1887. Serial No. 239,663. (No model.)

To all whom, it may concern:

Be it known that I, ARTIFE ANDERSON, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Windmills; and Ido 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 appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures oi reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is arepresentation of this invention andis a side view. Fig. 2is also a side view, but with the vane reversed. Fig. 3 is a top view of a portion of Fig. l. Fig. 4. is a top view othJ portion of Fig. 2. Figs. 5 and 6 are details.

This invention has relation to windmills; and it 'consists in the construction and novel combination of devices,as hereinafter set forth.

The object of the invention is to provide automatic governing devices which are of simple and durable character, and which are adj ustable, lso that the resistance of the rudder-vane may be varied.

In the accompanying drawings, the letter A designates the main pipe, which turns on the journal Z and carries the main casting B, which supports the wind-wheel, which may be of ordinary construction, and is not shown in the drawings.

The casting B is provided with a lateral bearing, O, extending transversely and adapted to receive a link, D, which, by means of the pin E and the pinholes c, is adjustable forward or backward in said bearing, a pin, E," passing through eyes of the bearing and of the link, serving to fix the latter in its adjusted position, and at the same time allowing the link to turn outward.

F is an adjustable collar on the pipe A, said collar being adjusted by turning'it on the pipe and fixing it in the position required bymeans of a set-screw, G. The collar is formed with a shoulder or stop, H, and by the adjustment 'of' the collar this stop is set farther to the right or to the left, as may be required.

Above the collar F is located the movable collar or turningv ring K, which is provided with a shoulder or stop, L, adapted, when the wheel is turning out of the wind,to engage the stopHof the collar F. Io an arm of this ringK is pivoted the short link N, which is adapted to turn horizontally on its pivot, as indicated. The top guide-rod, P, is pivoted to the outer end of the short link N and extends downward and outward at an inclination of about forty-five degrees to the front portion of the rudder-vane V, to which it is connected. To the lower link, D, is pivoted the main vane-rod R, which extends outward horizontally, or nearly so, and is rigidly secured to the rudder-vane at the front portion. The vane is thus supported by the combined action of the rod R and the top guide-rod, P, these rods divergin g from each other, as shown.

. When the wind rises, the action thereof on the vane draws the wind-wheel around out of the wind, and in this operation the casting B is rotated by the side draft of the vane until thestop of the collar-bearingF engages the stop of theringK,after which the ring can no longer turn with the collar F. The short link N, however, being pivoted to said ring, allows the casting to turn farther, and at the same time, by the angular position which it now takes with reference to the arm of the ring K, to which it is pivoted, the distance between the pivotal center of said ring Kand the point of attachment of lthe top guiderod to the vane becomes materially shortened, and the angle of divergence of said top guide-rod from the vane-rod R is increased, so that the vane is raised. As the force of the wind becomes less, the vane falls and turns the wheel in the wind.

By setting the adjustable collar F farther to the right the engagement of its stop with the stop ot' the turning ring is caused to take place more quickly when the wind increases, so that the resistance offered by the rudder-vane is increased.- If adecreased resistance is desired, the collar F is adjusted to the left, so that the vane will not rise so high in drawing the wheel out of the wind. It will also be observed that the lower link-connection, D, is also adjustable toward and from the vane. When adjusted toward the vane, by moving its pivotal connection in that direction, the leverage of the rudder-vane will be decreased, because the horizontal variation between the pivotal cen IOO ters of the link D and the pipe axis will be lessened. When, however, this variation is increased by adjusting the pivotal point of the link D away from the vane, the leverage and consequent resistance of the ruddervane will beincrcased. A second stop, S, is usually provided both on the collar F and on the ring K, so that the rudder-vane may be adjusted at a higher angle in the wind when advisable. These adjustments are readily made, and are so devised in order that the wheel may be brought out of the wind at any increase of resistance which may be practically desirable.

It will be further observed that as the casting is turned in drawing` the wheel out of the wind the rudder-vane not only rises, but moves forward or toward the axis of the pipe A, having thus a kind of thrust forward against the wind, which is of importance in-prevent ing irregular or spasniodie action of the wheel in a variable wind.

Having described this invention, what I claim, and desire to secure by Let-ters Patent, 1s

1. In a windmill, the automatic adjusting device to increase the rise of the vane, consisting of the stop-collar adj ustably connected to the upper portion of a pipe rising,` from the turning casting,` to which the wheel is attached, a stop-ring movable on said stop-collar, the

upwardly-inclined top guide-rod pivoted at its lower and outer end to the vane and connected at its upper and inner end to the stopring, and the vanerod connected to the turning casting, substantially as specied.

2. In a windmill, the combination, with the journal Z, the pipe A thereon, and the casting B, of the stop-collar F on said pipe, stop-ring K, movable on said collar, links D and N, respectively connected to the stop-ring and casting, top guide-rod, I, vanerod R, and vane, substantially as specified.

3. In a windmill, the combination, with the journal Z and the pipe A, of the casting B, having the lateral bearing C and the eyes c, the link D, adjustable in said bearing by means of' the pin E, and eyes, substantially as specified.

4. In a windmill, a rudder vane supported by diverging rods respectively pivoted toa lower adjustable link and to an upper link pivoted to a ri ng movable on au adjustable stop-collar, substantially as specified.

In testimony whereof I affix my si gnature iu presence of two witnesses.
