UNITED STATES HENRY K. HENN IGH, OF NEWCASTLE, INDIANA.

WINLDMILIJ. Y

Application filed February 1v1, 1924. Serial No. 692,121.

To all whom t may concer/lt:

Be it known that I, I-IENRY K. HENNIGH, al citizen of the United States, residing at Newcastle, `in the county of Henry and State of Indiana, have invented certain new and useful Improvements in IVindmills, of which the following is a specification My said invention relatest to a wind mill and it is an object of the invention to provide a construction which shall utilize effectually the power of the-wind and which at the inactive side of themill shallofler as little resistance as possible to the wind.

Referring to the accompanying drawings, which are made a' part hereof and on which similar reference characters indicate similar parts,

Figure 1 is a perspective of my device,

Figure 2 is a side elevation with parts broken away, and

Figure 3 a detail of certain parts of the framework on a larger scale.

In the drawings reference character 10 indicates a rotary post on which are supported a plurality of vanes 11. Each of these va-nes is carried on a horizontal bar 12 on which it is supported by means of a sleeve 18 forming part of the supporting frame. of the vane, such frame being located at the rear side of the vane. The

remaining members

14, 15, 16 and 17 of each framework are held together by pipe j oints and elbows as here shown or some other form of frame held together by different means may be substituted if preferred. At the outer ends of the rods 12 I have shown devices 17 here illustrated as T-joints screw-threaded to sleeves 13 through which are threaded wires 18 connected at their upper ends to a cap 19 on the post 10,

Abutments may be provided for limiting the relative movement of oppositely located vanes such abutments being here shown as including horizontal pipe sections 20, vertical pipe sections 21 secured thereto by elbows and horizontal pipe sections 22 extending through four-way connections joining successive sections of the post Y10, the sections 22 being secured to the sections 21 by T-joints or in any other desirable manner. The section 22 is loosely supported in the post so that the entire device can be moved by either one of the vanes at the ends of the corresponding rod 12.

The downward movement of each vane is limited by a rod 23 also mounted on the post 10 and it will be evident that assuming Y the wind to be blowingin thedircction of the arrow, the vanes will take the positions indicated in Figure 1 of the drawing. All the vanes normally hang below the horizontal plane passing through their axes so that the wind may force them down into approximately vertical position as seen at the righthand side of Figure 1 when in active position. At the same time the vane directly opposite is forced: upward toward horizontal positionby the wind and the action of the wind on the two vanes causes them to cooperate to move quickly into the desired positions thereby maintaining each vane in its active position during the greatest possible arc of the circle traversed thereby in the operation of the windmill. The position of the intermediate vanes will be determined largely by gravity, the vane approaching the active position tending to fall into an intermediate position and dragging the opposite vane out of active position toward an intermediate position. This action on the part of the vanes approaching active position tends to bring them into the vertical position ready to receive the impact of the wind vwith full effect.

The post 10 may be supported in any way that will permit free rotation and ready transmission of power therefrom when used as a power generating device. In the present instance I have shown Va sleeve 24 fixed in

supports

25 and 26 each of which may be rigidly secured to a plurality of legs 27 by which the entire device is carried.

It will be obvious to those skilled in the art that various changes may be made in my device without departing from the scope of the invention and therefore I do not limit myself to the specific form shown in the drawings and described in the specification but only as indicated in the appended claims.

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

l. A wind mill comprising radially arranged horizontal vanes, a sleeve between approximately 90 to each other, substantially as set forth.

2. A wind mill comprising a post, a radial series of independent pivots thereon, vanes on the pivots, and means pivoted on said pivots for holding opposite vanes spaced from each other at an angle of 90, substantially as set forth.

3. A Wind mill comprising a base, a radial series of independent pivots thereon, vanes on the pivots, and means pivoted on said pivots for holding opposite vanes spaced fromeaoh other at an angle of 90, substantially as set forth.

4. A Wind mill comprising a base, a radial series of independent pivots thereon, vanes independently mounted `on they pivots, and pivoted means for spacing opposite vanes in planes approximately perpendicular to each other, substantially asset forth.

5. A Wind mill comprising a post, rods extending through the post, pivots on each 20 rod at opposite sides of the post, vanes carried by said pivots, a sleevel about the rod extending through the post, and oppositely extending lingers on the sleeve adapted to engage the rear faces of the vanes, substantially as set forth.

6. A wind mill comprising a post, a rod extending through the postpivots on thel rod at opposite sides of the post, vanes carried by said pivots, a sleeve about the rod extending through the post, oppositely extending fingers on the sleeve adapted to engage the rear faces of the vanes, and fixed lingers below the rod for limiting the pivotal movement of the vanes, substantially as set forth.

In Witness whereof, I have hereunto set my hand at Newcastle, Indiana, this 26th day of January, A. D. nineteen hundred and tWenty-four.
