WINDMILLL I N0.'581,311. Patented Apr. 27, 1897.

y a 5 I H Ill UNITED STATES ATENT OFFICE.

EDWARD J. SGOVEL AND CHARLES F. ROSS, OF SAUNEMIN, ILLINOIS.

WINDMILL.

SPECIFICATION forming part of Letters Patent No. 581,31 1, dated April 27, 1897. Applioation filed April 6,1896. Serial No. 586,446. (No model.)

To all whom it may concern:

Be it known that we, EDWARD J. SoovEL and CHARLES F. ROSS, citizens of the United States, residing at Saunemindn the county of Livingston and State of Illinois, have invented a new and useful Windmill, of which the following is a specification.

The object of our invention is to provide a simple, inexpensive, powerful, and durable windmill for pumping water and running machinery.

In the accompanying drawings, Figure 1 shows the entire windmill ready tobe supported by a tower in a vertical position. Fig. 2 represents a top view of the fans, and Figs. 3 and 4 illustrate the hand-operated means for throwing the vane into the operating position.

The case in Fig. 1 is constructed in the form of a tube and may be of any size and length, depending wholly upon theheight of the tower employed.

We propose to construct the case from matched flooring, galvanized iron, or any other suitable material,and,when constructed of matched flooring, hoop it thoroughly with iron bands.

The shaft D may be any ordinary iron or steel shaft, and is held in position by boxes at bottom and top of case, as shown in drawings, and extends far enough above the case to support the hood B in proper position.

The hood B is of galvanized iron and in the form shown in drawings. It is supported in position by boxes G and F. The box G allows the shaft to pass through it, and the box F is a cap which fits over the end of shaft, holding up the weight of the hood and allowing it to revolve with the wind.

The tail 0 is constructed of boards or iron and its rod passes through boxes at front and rear of hood, as shown in the drawings. At

the front of the hood is a spiral spring J, fastened to the tail rod and box, as shown.

When the tail 0 stands in a vertical position, the spring J is in tension and the tail is held in position by a ratchet-wheel H and dog I. When the dog is lifted, either by hand or governor, the spiral spring revolves the tail one-quarter way around, bringing it to a horizontal position. The wind no longer acting upon the tail with sufficient force the hood swings around facing from the wind and the mill stops.

The dog I may be operated either by hand or by wires extending nearly to the ground, as shown, or by governor E, at the will of the operator.

In practice we usually form the cogged or toothed portion of the shaft with a single notch to receive the pawl by which the vane is held in operating position, and in order that the vane may be brought back to operating position by hand we supply a sleeve 1, journaled in the shaft and having a recess 2, into which a pin 7 on the shaft projects. Such sleeve has a crank-arm 3, from which a cord or line 4 extends to the ground, and a pitman 5, connecting the crank 3 with the pawl or dog, such pitman having a sliding connection at owith the dog, so the latter may be automatically lifted without disturbing the sleeve on the shaft. Manifestly the means for bringing the shaft back by hand may be modified without departing from the principle of our invention.

The governor is placed there to throw the mill out of gear in case of a sudden storm or gale.

The fans, as shown in Fig. 2, are to be constructed of metal or wood and fastened to arms (four, more or less) bolted to a casting, which is supported on a shaftby set-screw, these fans having the same angle and so placed on shaft as to present an open spiral surface to the wind, as shown in the drawings.

At the bottom of the shaft is a bevel-pinion for transmitting the power.

WVe place our fans on the shaft in such a form and distance apart as to secure as near as possible a screw or anger shape, so that the Wind acting upon one section of the fan glances onto the next one below it and so on throughout the entire length of the shaft. This together with the great amount of surface offered by the several fans enables us to secure a great amount of power, so that the mill will run and do good work in a very light breeze. In practice, the air at the surface of the ground being much warmer than it is at the mouth of the hood, the cool air will flow down through the case by virtue of its greater weight.

\Vhat we claim as new, and desire to obtain Letters Patent upon, is-

1. The combination of the case, the hood adapted to turn, the shaft in said case provided with the wheel or wheels, the vane adapted to hold the hood to the wind a spring by which the vane may be thrown out of operative position, a detent by which the vane is held against the action of such spring and means by which said detent may be released substantially as shown and described.

2. The combination of the case, shaft and wind wheel or wheels, the hood turning into and out of the wind, the vane whereby the said hood may be held to the wind, means by which the vane is secured in position to hold the hood to the wind and intermediate devices between said means and the wheel-shaft whereby the shaft may operate to release said means sub stantially as shown and described.

3. The combination of the case, the shaft therein and the wind wheel or wheels, the hood, the vane journaled to said hood, the spring for turning the said vane, the detent for holding said vane against the tension of the spring and a governor connected with said detent and arranged for operation by the wheel-shaft substantially as shown and described.

4. The combination of the hood, the case and wheel-shaft, the vane journaled to the hood and having a cog or toothed portion a detent engaging said cog portion a governor operated by the wheel-shaft and arranged to release the detent from the cog portion, and a spring for actuating said vane substantially as shown and described.

5. The combination in an apparatus substantially as described of the hood, the vane connected therewith, the spring by which to adjust said vane to inoperative position, a detent by which such vane is held against the action of the spring and means for releasing the detent substantially as shown and de scribed.
