SPECIFICATION formingpart of Letters Patent No. 715,480, dated December 9, 1902. Application filed October 7,1902. Serial No. 126,262. lilo model.)

T0 at whom it may concern.-

Be it known that I, JOSEPH GEORGE HUD- sPITH, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented new and useful Improvements in Motors, of which the following is a specification.

My invention relates to improvements in motors such as are designed more especially to be actuated by wind; and it consists in a certain peculiar motion the novelty, utility, and practical advantages of which will be fully understood from the following description and claims when taken in connection with the accompanying drawings, in which Figure 1 is a plan View of a motor constitilting the preferred embodiment of my invention; Fig. '2, a vertical diametrical section of the same, taken in the plane indicated by the broken line 2 2 of Fig. 1; Fig. 3, an enlarged detail section taken in the plane indicated by the broken line 3 8 of Fig. 2; Fig. 4, a detail horizontal section taken in the plane indicated by the broken line 4 4 of Fig. 2, and Fig. 5 an enlarged vertical section taken in the plane indicated by the broken line 5 5 of Fig. 2.

Similar letters of reference designate corresponding parts in all of the several views of the drawings, referring to which Aisa support or tower; B, a shaftj ournaled in the support and designed to be connected with a pump or other device to be driven; B, a sleeve loosely mounted on the shaft B and having a sprocket-gear Ct; G, a vane connected to the sleeve B in the manner illustrated or in any other preferred manner; 1), a spider or main wheel fixed on the shaft B above the vane and having eight (more or less) arms b and also having a bridge-bar c interposed between and connected to two of the arms adjacent to the outer ends thereof; E, a short shaft journaled in the bridge-bar and having sprocket-gears d e, exactly twice the size of the gear a, fixed on its upper and lower ends by set-screws, as shown, or other suitable means; F F, rods fixed to and rising from the arms 17 of the main wheel at or adjacent to the outer ends thereof; G G, hollow shafts loosely mounted on the said rods and equipped with blades H; I I, sprockets fixed on the hollow shafts G, preferably through the medium of set-screws, as shown; J, an endless sprocket-chain connecting the sprocket-gear c1. of the vane G and the sprocket-gear e on shaft E, and K an endless sprocket-chain surrounding and engaging the several sprocketgears I and the sprocket-gear d on the shaft E.

In setting up or adjusting the parts of the improved motor for operation the set-screws fastening the several gears I to the hollow shafts G are loosened to render the gears loose on the shafts, the vane G is held against movement, the main wheel D is rotated, and each blade as it reaches the position marked No. 1 in Fig. l is turned until it rests at right angles or approximate right angles to the vane C, after which the sprocket-gear on its shaft G is fixed to said shaft by tightening the set-screw in the gear against the shaft.

When all of the blades are adjusted as described above, the mill is ready for operation, and it will be observed that when the main wheel is turned each blade will make one-half of a revolution incident to each revolution of the main wheel, and in making the half of a revolution each blade will be presented in various positions to the wind, as plainly shown in Fig. 1. In other Words, when each blade is in the position diametrically opposite to position No. 1 its edge is presented to the breeze or current of air, and in consequence it does not retard the rotation of the Wheel. As soon, however, as it leaves the position opposite position No. l and moves toward the latter position it begins to gradually turn and present its outer side to the breeze until when it reaches position No. 1 its full area is presented to the breeze or wind.

The blades H are rotated as described incident to the rotation of the main wheel through the medium of the vane 0, gear a, chain J, gear 6, shaft E, gear (Z, chain K, and gears I. The chain J, shaft E, gears d and e, and the chain K are held against movement by the retention of the vane in the position shown in Fig. l, and the gears I, moving with the main wheel and engaging the chain K, turn the blades. When the wind veers and the position of the vane O is changed thereby, motion is transmitted to the several blades through the connection described, with the result that the described relative arrangement of the blades is retained.

In order to render the mill idle, it is simply necessary for an attendant to turn the vane C until the same rests in a horizontal position, with its edge to the wind. When the vane is thus turned, the wind will turn the main wheel until the blade shown in Fig. 1 as diametrically opposite the position No. 1 is square to the wind. The wind will then strike the said blade at right angles and will pass at either side of the same, with the result that the wheel will remain idle.

The blades H on the several shafts G are by preference relatively arranged, as shown in Fig. 2, this in order to permit the blades on each shaft to pass the blades on the adjacent shafts without striking the same and to allow a portion of the wind to pass between the blades at that side of the wheel which it first strikes and strike the blades at the .opposite side of the wheel with undiminished power.

While my improved motor is designed more especially to be actuated by wind, it may also be used to advantage as a water-motor. When it is put to the latter use, the wheel is disposed vertically instead of horizontally,when the vane will gravitate to the position necessary to retain the blades in the proper relative positions, and the blades will be struck by water falling from above when they are in their upper positions and also when they are in their lower positions.

I have entered into a detailed description of the construction and relative arrangement of the parts embracedin the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my invention as claimed.

WhileIhaveshown and described the windwheel as arranged horizontally, I do not desire to be understood as confining myself to the same, as the wheel may be arranged ver= tically or at any angle from the vertical desired without involving a departure from the scope of my invention.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. In a motor, the combination of a suitable support, a shaft journaled therein, a wheel fixed on the shaft, rotary shafts mounted on. the wheel, and carrying blades; the blades of each shaft being arranged to lap and pass the blades of adjacent shafts without striking said blades, and means for rotating the shafts on the wheel incident to the rotation of the wheel.

2. In a motor, the combination ofa suitable support, a shaft journaled therein, a wheel fixed on the shaft, rotary shafts mounted on the wheel, and carrying blades; the blades of each shaft being arranged to lap and pass the blades of adjacent shafts without striking said blades, a vane, and means controlled by the vane, for rotating the shafts on the Wheel incident to the rotation of the wheel.

3. In a motor, the combination of a suitable support, a shaft journaled therein, a wheel fixed on the shaft, rotary shafts mounted on the wheel and provided with blades, and sprocket-gears; the blades of each shaft being arranged to lap and pass the blades of adjacent shafts without striking said blades, an endless sprocket-chain surrounding and engaging the said sprocket-gears, a vane loosely mounted on the first-mentioned shaft, and having a sprocket-gear, a shaft journaled in the wheel, and having sprocket-gears, one of which is engaged with the endless sprocketchain, and an endless sprocket-chain connecting the other gear of said shaft and the gear of the vane.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH GEORGE HUDSPITH.
