EMERSON F. BALDWIN, OF PHILADELPHIA, PENNSYLVANIA.

WINDMILL CONSTRUCTION.

To all whom it may concern:

Be it known that I, EMERSON F. BALDWIN, a citizen of the United Stat-es, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in lVindmill Construction, of which the following is a speciiication.

The principal object of the present invention is to provide a wind-mill construction in which a pair of wind-power wheels carried at the opposite ends of a horizontally arranged shaft are equally balanced upon a tower; said shaft being arranged to move freely in a horizontal plane, so that the said shaft will always be at right angles to currents of air.

A further object of the invention is to provide a wind-mill construction in which the wind-power wheels are so arranged upon the power shaft that the wings or vanes thereof are afforded a reciprocal movement and when above the horizontal plane of the shaft face the wind and when below the horizontal plane of the shaft cut the wind.

A still further object of the present invention is to provide means whereby the operation of the wind-mill may be automatically or manually stopped by causing all of the wings or vanes of the wind-power wheels to cut the wind in contradistinction from facing the wind.

Other objects of the invention relate to general details of construction and arrangement of parts as will hereinafter more fully appear.

The invention consists of the improvements hereinafter described and finally claimed.

The nature, characteristic features and sco e of the invention will be more fully understood from the. following description taken in connection with the accompanying drawings, forming part hereof and in which:

Figure 1, is a view of the upper portion of a wind-mill, embodying the invention, said view being partly sectioned, Fig. 2, is a view in plan taken upon the line 2 2 of Fig. 1, Fig". 3, is a fragmentary view of a detail of construction shown in Fig. 2, and Fig. 4, is a det-ail view partly sectioned, illustrating the position of one of the wings 0r vanes of a wind-power wheel when cut- Specication of Letters Patent.

ting the wind at a period when the machine has been brought to rest.

In the drawings, the tower which may be of any suitable construction is designated 1. Surmounting the tower is a fixed plate 2, provided with a tooth ring 3, forming a circular track. Adapted to travel around this track are cog-wheels 4, surmounting which is a rotatable plate 5, provided with a tooth ring 6, meshing with the cog-wheels 4. The plates 2 and 5, are provided with flanges 7, that serve to retain in proper position the various parts. Arranged diametrically with respect to the plate 5, and capable of rotating around its own axis as well as horizon tally in its plane is a shaft 8, the ends of which extend beyond the tower. Carried by and xed to the respective ends of the shaft 8, are members 9, provided with sockets for the reception of a series of radially extending arms 10, that are arranged at right angles to the shaft S. Movably mounted upon each of these arms 10, are two blocks 11, and 11a, provided with cam-surfaces 12, which coperate with fixed pins 13, on the arms 10, for a purpose to be presently described. Having fixed relation with these blocks and connecting each pair of blocks on each of the arms 10, are strips 14. Extending at right angles from these strips 14, are a series of rods 15, that support blades 16, that go to make up the wings or vanes of the wind-power wheels.

In operation as the wind-power wheels just described are moved to face the wind through the instrumentality of the rudder 17, the plate 5, will partially revolve, thereby turning the wind-power wheels sufficiently to cause all of the vanes above the horizontal plane of the shaft 8, to face currents of air, or, in other words, to lie in the same plane with the shaft 8. As currents of air impinge upon the vanes of the wind-power wheel above the horizontal plane of shaft 8, the wheels are caused to rotate around their own axis. As the arms 10, of these wheels rotate around their own axis and pass beyond the horizontal plane of the shaft 8, either going up or coming down, the vanes thereof gravitate thereby causing the camsurfaces 12, of the blocks 11 or 11a, to act upon the fixed pins 13, and move for a quarter turn the blade 16, so that above the Patented Mar. 15, 1910.

horizontal plane of the shaft 8, said blades face the wind and below the horizontal plane of said shaft cut the wind. In other words, the blades 16, have been moved from the position shown in the upper portion of Fig. 1, to the position shown in the lower portion thereof.

Referring now more particularly to Figs. 2 and 3, a description will be given of the manner of either automatically or mannally causing the stoppage of the wind-mill. Extending diametrically across the plate 5, is a beam 1S, having hinged relation with which as at 19, is an obliquely extending rod 20, provided at its upper end with a wind-plate 21, and at its lower end with a counterweight 22 (see Fig. 3). The rod 20, may be held in such oblique position by means of a chain 23. Freely connected with the rod 20, are connections 24, that extend rearwardly from said rod 20, and terminate in rings 25, that are connected with collars of shiftable members 26, having keyed relation with the shaft S, as at 27. These shiftable members 26, may be provided with plates 28, passing through which are stems 29, that contact with blocks 30, mounted so as to be rotatable around each of the arms 10. The stems 29, are provided with nuts or the like 31, connecting which and the plates 28, are springs 32. The blocks 30, are provided with pins 33, adapted to engage with a series of notches 34, upon the blocks 11a` of each rod 10. In the normal operation of the wind-mill, the above described mechanism remains idle in the position shown in Figs. 1, 2 and 3. This is due to the fact that the weight 22, is so arranged that ordinary currents of air will not affect the wind plate 21. However, should a great wind disturbance take place, currents of air will drive the wind plate 21, in the direction of the arrow (see Fig. 3), thus spreading the rods 24, and shift the members 2G, in the directions of the arrows (see Fig. 2), to cause the blocks 30, on the arms 10, to sufficiently rotate around these arms so that the pins 33, will engage one of the notches 34., of the members 11, as each vane of the power wheels drops below the horizontal plane of the shaft S, thereby causing all of the vanes of the power wheel to be substantially at right angles to the power shaft 8, as clearly illustrated in Fig. 1. The strength of the wind impinging upon the plate 21, determines the heightto which the weight 22, is raised and the consequent distance through which the blocks 30, will rotate and will also determine under which of the notches 34, the pins 38, will assume their positions. In this way, the strength of the wind determines the angle at which the vanes above the horizontal plane of the shaft 8, present themselves to the wind. By these means, the vanes of the power wheel will cut the wind in contradistinction from facing it, thereby bringing to a stand-still the mechanism of the wind-mill. As shown in Fig. 3, manual means as 35, is shown for accomplishing the same result.

That I claim is 1. In combination a tower, a horizontally arranged shaft upon said tower and capable of being rotated around its own axis and of being revolved in a horizontal plane, windpower wheels carried by the respective ends of said shaft said wheels comprising a series of radially arranged arms carrying reciprocating gravity vanes whereby during the operation of the apparatus the vanes above the horizontal plane of said shaft face the wind and the vanes below the horizontal plane of said shaft cut the wind and means operatively connected with said shaft for transmitting power.

2. In a wind-mill construction a horizontally arranged shaft, wind-power wheels at the respective ends thereof comprising a series of radially arranged arms carrying vanes, capable of a reciprocating movement for the purpose of presenting wind-receiving and cutting surfaces, and means for shutting off said reciprocating movement.
