SPECIFICATION forming part of Letters Patent No. 285,960, dated October .2, 1883.

Application filed November 12, 1880. (No model.)

To (6 whom, it may concern Be it known that I, JOHN M. Born, a citizen of the United States, residing at Oakfield, in the county of Fond du Lac and State of \Visconsin, have invented certain new and useful Improvements in \Vi n d WVheels; an d I do here- .by 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 appcrtains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention has for its object to furnish a wind-wheel which will possess superior advan tages over ordinary wheels; and it consists in the peculiar construction and arrangement of the several parts hereinafter fully explained, and pointed out in the claims.

In the drawings, Figurel is a side elevation of my wind-wheel partly in section. Figs. 2 and 3 are sectional views of the sliding collar. Fig. 4 is a side elevation of the sliding collar and its attached rim or frame. Figs. 5 and 6 are detached segments of the wheel, showing their construction more in detail than is shown in the wheel in Fig. 1.

A is a tubular shaft supported in bearings a a, fastened to the upright frame B. To this shaft are secured a lateral arm or support, 0, and an upright arm, I), the arm (I having shaft-bearings c c.

l) is the wheel-shaft hung in the bearings c, with one end connccted,by a crank pin or arm, (I, and other suitable means, to alever, c. The lever e is pivoted at one end to a suitable sup port upon the arm C, while its other end is connected to the upper end of a rod, E, which is connected to a tubular extension, E, extending down into and through the shaft A, and swiveled to the piston-rod.

c is a guide for the lever c.

F is a sleeve adapted to slide on the shaft 1), with an extension, F, overhanging to prevent the accumulation on the shaft of snow and ice, which would interfere with the operation of the sleeve.

\Vhen the wheel is at rest and a driving rain which freezes as it falls, or a driving snow-storm, prevails, water or snow may be driven under the shield F and frozen on the shaft I). The moinent the wheel would be set in motion the revolution of the shaft and the to-and-fro movement of the sleeve would tend to remove instantly the accumulated ice. The extension or shield F does not fit snugly against the shaft D, but is formed with an enlarged opening and stands out from it, so as to provide an air-space between it and the shaft, as shown. The object of this is to prevent ice from forming on the shaft immediately against the end of the metal sleeve. If the shield were simply an extension of the sleeve F and fitted close againstthe shaft, its end would present the same abutting face as the end of the said sleeve. If ice form under the shield, it will be in a very thin layer as it extends toward the end of the sleeve, and will be easily broken by the movement of the latter. The extension or shield is also slotted longitudinally on its under side, so that any water or snow that may be blown under it will readily drop out.

To the sleeve F is pivoted, at itsforked end, a lever, (i, with its other end connected to one arm of a weight-lever, H, hung or pivoted upon the arm 0. A wire or rope, f, is con nected to a second arm of the lever H and passed down through the tubular extension of rod l and is provided with a swivel, andconnected to a handle within convenient reach of the operator or attendant. This arrangement, by pulling upon the wire or ropef, permits of the elevating of the lever H and drawing upon and sliding rearward] y the sleeve F,which, as will be more readily understood hereinafter, adjusts the sails or sections of the wheel out of the wind. the sleeve has a contrary effect. The sleeve F is provided with a circular rim, I, connected thereto by radial arms or spokes, two of which point outward and downward from the sleeve F, one on each side of the support 0. This arrangement allows the rim I to pass outside and underneath the support O.

The rim I has a peripheral flange or rib, i, upon which is fitted, so as to move with the wheel, an internally-grooved annulus or ring,

I, with eye i. J' J are elbows or bell-crank levers pivoted. at their angles to the spokes or radial arms of the wheel K, with its hub K fast upon the shaft 1'). These levers are con- A vice-versa movement of i to the slot 02.

nected by rods j, entering the eyes 1; on the It will be seen that one roller placed upon rings I, and by means of a small casting, a, to rods j, passing through eyebolts 7c of bars 75, which connect the two cross-bars of each sail or section, thus connecting two sails or sections with each of the levers J. Each sail or section is pivoted between two of the arms or spokes of the wheel K by means of a bracket, 1, having a journal formed upon it. There are only two of these brackets fastened one on each end of the longer crossbar 70 of each sail or section. The journal of the bracket is on the under side of the crossbar and works in a bearing formed in an ear, '6, attached to the end of the arm or spoke K of the wheel, thus allowing each sail or section to be thrown out of the wind by the centrifugal force as the speed of the wheel increases, and also forming a tie between the arms or spokes of the wheel. This completes the description of the sail-operating mechanism.

The dotted lines in Fig. 1 indicate the position given the sails when it is desired to adjust them out of the wind, the full lines indicating the reverse.

L is a vane hu'ng upon the shaft D, and weighted at its lower edge, as at L, to prevent its revolving with the shaft. The vane is 'used for the purpose of making the mill shift easily and to prevent the wind-wheel from getting edgewise to the wind when running in a light breeze. The small casting or connectingpiece a is formed with 'a mortise or crossslot, at, on one of its ends and on its opposite end with the slot or mortise a at right angles By means of this casting, thus constructed, I am enabled to give a perfectly f.-ee play to the levers J and rods j as the sails are thrown inor out of the wind. There is no binding between the said levers and rods, and consequently no lost power.

0' is a rod passing from the arm 0 around under the support 0 and back on the opposite side. It helps support the mill.

0 is a roller, of which there are two attached on opposite sides of the tubular shaft A, underneath the collar a, to prevent the mill from being lifted out of its bearings in a gale.

the tubular shaft A, underneath the collar a and directly under the support 0, would answer the same purpose.

' It will be readily understood that this mill is simple in construction and not liable to get out of order, shifts easily, governs automatically, and cannot be easily clogged with snow 1 or ice.

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

1. In a wind-wheel, the combination, witl the shaft D and arm or support 0, of the sleeve or collar F, sliding upon the shaft and provided with radial supports, and the rim I, fixed on the radial supports, and passing outside and underneath the support 0, as shown, substantially as and for the purposes set forth.

2. In combination with a sliding collar or sleeve, F, carrying a rim, I, provided with a peripheral flange or rib,o7, an internally-grooved annulus or ring, I, provided with ears, substantially as set forth. 7

3. The combination, with the rod j and bell-crank lever J, pivoted to the arms K, which support the fan-sections k of the cast ing at, having slots at a formed in its opposite ends, at right angles to each other, and pivoted to the ends of the said lever and rod, substantially as set forth.

4. In combination with the shaft D, the vane L, hung upon said shaft in rear of wind-wheel, and weighted at its lower edge to prevent revolving with said shaft.

5. The combination, with the shaft D and sleeve F, of a shield or extension, F, surrounding or partially surrounding the shaft and standing out so as to provide an open space or chamber between it and the shaft, substantially as set forth.

- In testimony whereof I affix my signature in presence of two witnesses.
