SPECIFICATION forming part of Letters Patent No. 333,566, dated January 5, 1886. Application filed October 22, 1885. Serial No. 1P0,6"75. (No model.)

To all whom it may concern.-

Be it known that I, GHARLES'V. STEVENS,

a citizen of the United States, residing at Somonauk, in the county of De Kalb and State of Illinois, have inveited a certain new and useful Improvement in \Vindmills, of which the following is a description, reference being had to the accompanying drawings, in which Figure 1 represents a side elevation of a windmill embodying my improvement; Fig. 2, a plan view of the same; Fig. 3, a front elevation with the wind-wheel removed, and Fig. 4 a detail perspective view showing the manher in which the side vane is mounted.

Like letters refer to like parts in all the figures of the drawings.

My invention relates to windmills, its object being to provide means for regulating the action of the mill under varyingwind-pressure; and to this end my invention consists in certain novel features, which I will now proceed to describe, and will then specifically point out in the claims.

In the drawings, A represents the upper portion of the framing or tower which supports the mill proper, and B the revolving support mounted in the said tower or frame, and having attached to its upper end the head 0, in which the shaft 01 of the wind-wheel D is mounted.

E represents the main vane, which is pivated to the face of the revolving support B, opposite to that upon which the Wheel D is mounted. This vane E is arranged with its pivots in the same vertical plane with the axis of the shaft d, the vane being thus normally central with relation to thewindwvlieel, as shown in Fig. 2 of the drawings.

F indicates a weight attached to a rope or cord, f, which passes over a pulley, f, mounted on the support B, and is connected to an arm, F, attached to the main vane E. It is obvious that this weight will maintain the vane normally in a position at right angles to the plane of the wind-wheel D. Any other similar construction may be employed for this purpose.

G indicates a side vane, which is pivoted to the main vane in any suitable manner, it being shown in the present instance as mounted upon an arm, E, depending from the main ings.

stem of the said vane. This side vane projects normally in a plane at right angles to the plane of the main vane, and is provided with an arm, 9, which is connected in any suit-'- able manner to an arm, B, projecting from the support B, as shown in Fig. 2 of the draw- This connection may be made directly by means of a suitable cord, rope, or chain; or it may be made, as shown in the drawings, by means of a cord, 9, attached to the arm 9, and to a similar cord or rope, G, which connects the arm B with the vane E. It being understood of course that the main vane E is always in line with the direction of the wind, 6 it will be seen that upon any undue increase in the force of the wind the side vane, G, will be turned upon its pivot, and will act upon the arm'B through the medium of the conmeeting cord or rope, thus rotating the sup-. port B and throwing the wheel D slightly out of the wind. As soon as the wheel D is thus thrown out of the wind, it has a constantlyincreasing tendency to turn out of the wind to a greater extent, owing to the fact that it 5.

presents a larger surface on one side of the plane of the main vane than on the other.

In order to overcome this tendency, I employ an auxiliary vane, H, which is attached to a stem or shaft, h, mounted on the head 0, so as s to be normally in line with the main vane E. As soon, however, as the wheel D is thrown out of the wind, as hereinbefore described, the vane H by the rotation of the support B and head 0 is presented to the wind on the opposite side, and tends to counteract the tendency of the wheel D to turn out of the wind to a greater extent, as hereinbefore set forth, and also to bring it up into the wind again as soon as the force of the wind diminishes.

I indicates a cord, which passes over a pulley, i, on the arm B, and is attached to the vane E, as shown in Fig. 2 of the drawings' This cord extends to the foot of the tower, so that by operating the same the vane E may 5 be drawn into a position parallel to the plane of the wheel D, which will thus be held entirely out of the wind and remain stationary.

In this position, however, the auxiliary vane H will present its full face to the wind, and

will tend to bring the parts back into operative position. In order to prevent this, I mount the shaft h of the auxiliary vane H in suitable bearings in the head 0, so as to permit the said shaft to rotate, and I connect an arm or projection, h, on the said shaft to the cord I by means of a similar cord, I, so that when the cord I is drawn down, as hereinbefore described, the shaft it will be rotated to cause the auxiliary vane H to assume a horizontal position, thus prcsenting its edge to the wind. A suitable weighted arm, J, is attached to the shaft h, in order to return the vane H to its operative position when the cord is released.

It will be seen from the above description that by attaching the side vane to the main vane and connecting it to the support, as described, I provide an efficient means for inaugurating the motion of the main wind-wheel out of the wind, and that by the use of the auxiliary vane the tendency of the main wheel to turn too far out of the wind is checked, and the said wheel is returned to its proper position when the force ofthe wind diminishes.

It is obvious that various mechanical modifications in the details of construction and the arrangement of the parts may be made without departing from the principle of my invention, and I therefore do not wish to be understood as limiting myself strictly to the precise construction shown and described.

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

1. The combination, with the main wheel and main vane, of a side vane pivoted to the main vane and connected to the main wheel said support in line with the axis of the main wheel, and a side vane pivotally mounted on the main vane and connected to the support of the main wheel, substantially as and for the purposes specified.

3. The combination, with the main wheel and its support, of the main Vane pivoted to the said support, the auxiliary vane mounted on said support in a position normally in line with the main vane, and the side vane pivotally mounted on the main vane and connected to the support, substantially as and for the purposes specified.

4. The combination, with the main wheel D and its revolving support B, provided with arm B, of the main vane E, pivoted to said support, and the side vane,G, pivotally mounted on the vane E, and provided with an arm, 9, connected with the arm B, substantially as and for the purposes set forth.

5. The combination, with the main wheel and its revolving support, of the main vane pivoted to said support in line with the axis of the main wheel, and the auxiliary vane mounted on said support in a position normally in line with the main vane, substantially as and for the purposes specified.

6. The combination, with the main wheel and its support, of the main vane and its operating-rope I and the auxiliary vane H, attached to a shaft mounted in hearings in the support and connected to the ropeI by a rope, I, to operate said auxiliary vane simultaneously with the main vane, substantially as and forthe purposes specified.
