UNITED STATES PATENT OFFICEO K JOHN H. MORSE, OF PEORIA, ILLINOIS.

IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 41,442, dated February 2, 1864.

To all wtowb it may concern,.-

Be it known that I, JOHN H. MORSE, ofthe city of Peoria, and county of Peoria and State of Illinois, have invented a new and useful Improvement in Windmills; and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure l is a perspective view of mill; Fig. 2, a Vaneframe with circular track; Fig. 3, a sectional view of bed of mill, showing the upper post of governor-frame 2, the manner of its action upon lever P to raise movable half of circular track, with bar J, wheels i, and' friction wheels D; Fig. 4, a horizontal view of vane; Fig. 5, a perspective view of vane B, with regulating-fan O, levers P P P p p p, and their action upon movable half of circular track.

My improvement consists in placing a circular track, H h, under a horizontal armed mill, with pivoted horizontal fans K K K. These fans are connected by a bar, J, running across and jointed to, opening and closing them similar to Venetian blinds. Half of this circular track H is movable and the other stationary. These two halves H and h are connected by aprons or bridges G g, forming inclined planes, so that the mill in revolving the wheels t', that carry the bars J, run down G, allowing the fans K to close, catch the wind, and continue closed until in running up g on the stationary halt` h will open and allowing the wind to pass through without giving any power to the mill; also, in a regulator, O, and governor It, so that as the power ofthe wind increases they will be acted upon, the fans K turned, exposing less surface to the wind, and, consequently, regulates Jthe speed of the mill.

The manner of building this mill and running it is as follows:

I place upon a circular table, A, supported by postsE E E E E E, a vane or weathencock, B, that will always keep the point C to the wind. This vane revolves upon friction-wheels D easily, and must, for upon this the whole working of the mill depends. Upon the frame of this vane B a circular track is laid in halves H h, onehalf, H, movable, the other, h, stationary and secured to the frame of vane. The two halves are hinged together by two aprons or bridges, G g, allowing the movable half H to drop below and raise to a level with the stationary half h. Upon this track runs six wheels, it t' it' t', attached to the lower end, and carrying six perpendicular bars, J J J J J J. These bars reach up and across each set of fans, K K K, connecting them similar to the slats in Venetian windowblinds, opening and closing them as the bar J is raised or lowered. These fans K K K (three or more may be used upon each pair of arms of the mill) are pivoted into studs L L. These studs are framed into the horizontal arms M M. Six pair of horizontal arms, M M M M M M, are fastened upon the main shaft N.

Now, as the mill revolves the wheels fi, carrying the bars J, are allowed as they pass the point c to run down the inclined plane or apron G. This will close fans K K K, catch the wind, and receive its power. As they pass on around they come to the inclined plane or apron g. In running up this thebars J will be raised, the fans KKK open and stand featheredge to the wind as they pass over the stationary half of circular track h to the point c, whenin passingthis point they again close to take the wind, and so on.

I also affix to therear or Windward of mill a regulating-fan, O, standing at an angle of about forty-tive degrees with face to the wind. This is jointed upon the bar that forms the rear of vane B and allowed to turn down to a horizontal position. This fan O is connected by levers P P P p p p with movable half of circular track H. The fan O is kept in position by weight of circular track H; or, if not sufficient, weight may be added, or aspring.

Itmust be able to withstand more force than will run the mill, else on the firstV force or power being applied it will be blown down, and the mill will not start or run.

The proper position for the regulator is at an angle of about fortyffive degrees. Then the movable half of circular track H is lower O `will be depressed by this eXtra force acting upon it. The levers P P P p p p will raise the movable half of circular track H and lessen the surface ofthe fans K K K exposed to the wind.

In case of a severe blow or hurricane, the

fan O will be forced down, the half-track H will be raised to a level with the other, h, the fans Will be turned feather-edge to the wind, and the mill stop until the fan O is allowed to raise by the power of the wind decreasing.

I also aflix a gear to the main shaft N, a governor, R, like thatk used on steam-engines. As the speed of the mill increases the balls R Will be extended. This will raise the frame Q. This bearing upon the lever P will raise the movable half of circular track H and assist the regulator O in keeping up an equal motion.

What I claim as my invention, and desire tosecure by Letters Patent, is-

The regulator 0 and governor R, or their equivalent7 acting upon the movable half of circular track H by means of levers P P P, or their equivalent, in the manner and for the purpose herein specified.
