WINDMILL.

SPECIFICATION forming part of Letters Patent No. 776,019, dated November 29, 1904.

Application filed March 19, 1904.

To all whom it may concern:

Be it known that I, EARL 1i]. GOULD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Windmills, of which the following is a specification.

The object of this invention is to provide a simple and eificient windmill in which the Wheel is positioned horizontally rather than vertically, so that rotation is imparted directly to the shaft without the necessity for gearing or other intermediate mechanism, and the wheel is so constructed that it will revolve whenever the wind is blowing without the necessity for a tail or other mechanism for turning the wheel toward the wind, since the blades of the wheel are so constructed that a pressure of wind from any point will bear against the blades of the wheel on but one side, the blades on the opposite side being so arranged that they will swing into the wind in edgewise position, thereby allowing the wheel to revolve and bring the blades successively from edgewise position when approaching the wind into transverse position when carried by the wind.

A further object of the present invention is to minimize the lateral pressure exerted against the tower or structure upon which the wheel is mounted, so that the operating parts may be sustained by a much lighter structure than is the case with vertical wheels against which strong lateral pressure is at all times exerted.

A further object of the present invention is to provide means for regulating and stopping the revolution of the wheel by adjusting the blades to maintain a uniform position on both sides of the wheel, in which case the revolution will stop, or by allowing a greater or less speed of revolution, depending upon the angular position to which the blades are adjusted.

-The invention consists in the features of construction and combination of parts hereinafter described and claimed.

1n the drawings illustrating the invention, Figure 1 isa side elevation of the wheel in operative position, showing the tower partially broken away; Fig. 2, a plan view of Serial No. 199,038. No inodelf the wheel with the wind in the direction indicated by the arrow, and Fig. 3 an enlarged sectional detail of the hub and mounting for the blades.

As shown, the wheel is mounted upon a square tower having supporting-uprights A, one at each corner, and said uprights are connected by braces of any usual and wellknown construction, and the tower is provided at its top with a platform (1 immediately beneath which and at suitable distance therefrom is a flooring a, which serves as a support for the operative mechanism. The wheel is constructed to have ahollow hub B, through which pass a series of laterally-extending rods 7), 7), and b and, as shown, the rods are rotatably mounted one above the other in the way indicated and project outwardly at each side, forming six arms in the construction shown, for the mounting thereon of an equal number of blades. In order to prevent the lateral displacement of the arms and at the same time allow of their rotation, said arms are each provided with collars I), which bear against the exterior face of the hub.

Upon the arms are mounted a series of six blades C, two blades being mounted upon each rod, and the blades are fixedly secured at their upper edges, one on each side, to the rods and positioned at right angles to one another, so that when the wheel is in normal position the blades will hang at an angle of about forty-five degrees from perpendicular, since the blades and supporting-arms are of equal weight on both sides of the hub.

The hollow hub is fixedly supported upon a shank 0, through which the arms pass, and

into said shank is inserted a rotary power shaft 0, which, as shown, is journaled to the flooring a and provided with a pinion c for imparting rotation, although it is obvious that the shaft may be carried down any suitable distance and that the power may be imparted thereby in any suitable and well-known manner. The shank c is preferably provided at its lower end with an outwardly-projecting flange and said flange serves as a support for a slidable sleeve D, which is provided, near its lower end, with flanges (Z, leaving a groove 11 for the insertion of a curved yoke which is provided at its end with an ear 6Z3, to which is attached a vertical rod E, which depends a suitable distance and is pivoted, by means of a pivot e, to a lever e, which lever is pivoted to a support 6 suitably and conveniently mounted upon the framework of a windmill, and said lever is adapted to engage a series of teeth 6 to regulate the vertical movement of the lever,and the lever is adapted to raise and lower the sleeve D. The sleeve is provided with a diagonal slot F, through which projects a stud f, which is carried by the shank, so that as the sleeve is thrust upwardly by the movement of the lever, it will be simultaneously rotated by the contact of the stud with the slot.

To the sleeve is attached an outwardly-projecting circular disk Gr, to which are secured a series of abutments g, and the abutments are so formed and arranged that they will serve to limit the downward movement of the blades when the same have assumed a vertical position, and, as will be seen from an inspection of Figs. 1 and 2, the abutments for the upper and middle blades of the wheel have a greater vertical elevation than the abutments for the lower blades, so that the blades will all be brought into vertical position before they strike against the respective abutments.

In operation with the wind in the direction indicated by the arrow in Fig. 2 the blade which is in direct transverse position to the wind on the operative side of the wheel will be thrown down against its abutment by the force of the wind, and the opposite blade on the same shaft will be thrown into edgewise position with respect to the wind, thereby causing the wheel to revolve until the next succeeding blade is brought into transverse position to the wind, so that the wheel will receive the impact of the wind on but one side, and the blades as they approach the wind will be successively thrown into edgewise position. As the blades are turned from transverse position they will receive the wind at a tangent and will begin to return to their normal angular position of forty-five degrees, and said return movement will be continued until the rod has turned through an angle of ninety degrees and brought the blade on the opposite end thereof into transverse position to receive the impact of the wind. By positioning the blades one above the other the forward blades, which are directly in the path of the wind, will not interfere to any material extent with the blades which are behind, which would be the case if the blades were all mounted in the same vertical plane.

When it is desired to impart the entire force of the wind to the wheel, the sleeve, with its disk and abutments carried thereby, is drawn down to its lowest position, so that the stud F will contact with the end of the diagonal slot and the lower flange (Z contact with flange 0*, which takes all friction off from the yoke d" and allows the blades to swing down into vertical position when in operative relation. By upwardly movingthe sleeve a portion of the distance it will also be forwardly turned toward the approaching blades, so that the samewill contact with their abutments before they have been able to swing into vertical position, thereby decreasing the speed of rotation of the wheel, and said decrease can be continued until the abutments are in their uppermost position, in which case the sleeve will have been turned a partial revolution and the abutments thrown into a position to hold all of the blades at an angle of forty-five degrees,thereby preventing any rotation of the wheel whatsoever.

It will be seen from the foregoing description that the windmill of the present invention is simple in construction and operation and that the parts are so regulated and adjusted that the wheel may be instantly stopped or its speed of rotation regulated without the necessity for the use of a tail or other complicated and cumbersome regulating means.

Although the device has been described with considerable particularity, it is obvious that the parts may be changed or modified without departing from the spirit of the invention.

\Vhat I regard as new, and desire to secure by Letters Patent, is
