WINDMILL.

Application filed February 20, 1926. Serial No. 89,722;

This invention relatesito devicesused in controlling windmills.-

One of the objects of this invention is to providecontrolling meansfor shifting and turning the vanes of the mill in certain relation to the wind wheel, by which the vanesing description and appended claims aswell as from the accompanying drawings, in wh1ch-.

Fig. 1 is a perspective somewhat diagrammatical illustration of a wind-wheel embodying the invention, the vane-controlling irockets being merelv rou hl outlined and L .1 G J the connecting gears and pulleys being left oif'to make the interconnection between the vanes and the several sprockets distinct.

Fig. 2'is detail longitudinal sectional view of the shafts, sprockets and gears.

Fig. 3 is a flat plan view of the cams in" form of slots in the tubular control memher for setting and holding the sprockets 1n certain positions.

Fig. 4 is .a diagrammatic side elevation of tliewind-wheel illustrating the vanes in certain'. operative positions.

Fig. 5 is a diagrammatic side elevation illustrating the vanes in another operative relation to one another.

Fig. 6 is a diagrammatic side elevation similar to the illustration in Fig. 4, in which the vanes have been illustrated in inoperative and ineffective positions.

From the illustrations in Figs. 4 and 6, it is readily understood how a forward or rearward turning of the vanes may tend and serve to bring and hold the vanes so as'to make the pressure of wind ineffective upon the wind-wheel. By providing means by which the vane 7 in Fig. 4 may be moved to the position indicated at 8 in 6. and the vane 9 of Fig. l to the position indicated at 10 in Fig. 6, and the vane 11 of Fig.

4 to the position indicated at'12 in Fig- 6; and the vane 13 of Fig. 4t to the position indicatedat, 14 in Fig. 6; wind whether coming from the front orfromthe rear, has llttle or no efi'ect' upon the vanes in such changed pOSlt-1OI1S;Wl1l'l,' 111' the positions inwhich thevanes are-illustrated in= Figs. 4 and 5, windh-as a distinct effect in one and the same direction in relation to therotating-of the wind-wheel upon each and.

all of the vanes.

The wind-wheel is illustrated in a horizontalposition though a vertical-arrangement may be ust as practical and effective;

In this horizontal Y arrangement, bases or:

uprights 15 are provided to turnably supportthe main shaft 16. The main-arms 17 are firmly mounted on the mainshaft, to

transmit the motionfrom the arms to the;

main shaft, to be further transmitted by pulleys or other customary transmitting;

means, a pulley 18being indicated on the end of 'the shaft 16 in 2; l

The arms 17 are provided with bearings 19 in which the vanes 7, 9,11, and 13areturn- The sprockets 2O serve to ably mounted. control the rotating movements ofthe vanes.

Othersprockets 21are mounted in operative relation-to the main shaft 16, andare operatively connected with the sprockets on the vanes by suitable flexible means 22.;

The sprockets and connecting means are merely roughly outlined and indicated in Fig. 1, to illustrate their operative relation, slnce their constructive details are of 'little" The direct connection between the main arms 17 with the pulley 18 through the main shaft 16 is illustrated in Fig. 2. A gear 23 is also firmly mounted on the main shaft, to transmit the motion of the shaft to other gears 24, 25, and 26, and further to a coupling member 27. A sleeve 28 is provided with corresponding coupling or engaging means 29, by which the motion of the main shaft 16 may be transmitted to this sleeve 28. The gears 24 and 25 are pivotally. mounted in the arm 30, which in turn is a part of a stationary sleeve 31. The statiouary sleeve 31 extends to the standard or base 15. The gear 26with the coupling member 27 is, turnably mounted on the stationary sleeve 31.

In operation, the rotating sleeve 28 is cou 2 unseen wind-wheel through the main shaft 16 and the arms 17.

To ell'ect a neutralizing of the wind-wheel, the rotating sleeve is disengaged from the gears and thereby from the main shaft, and other engaging or coupling means 33 on the op msite end of the sleeve 28 serve to hold the winduvheel in neutral positionby being brought into engagement with the corresponding engaging means 3%, on. the stationary sleeve and base.

The neutralizing of the windwl1ecl is further effected by a shifting of the sprockets 21 in a rotating direction, so as to turn the vanes to positions in which they .ofi'er a minimum and equalized wind surface. The rotating sleeve id is for this reason and purpose provided with curved slots of cam-like design, as indicated at 3&- in Fig. 3, into which inwardly ex tending lugs 011 the sprockets extend so as to be controlled by these cams. The sprockets are mounted on a sleeve 36, which shittably and at the same time rotatably mounted on theirotating sleeve :28. By a shifting ot the sprocket-carrying sleeve 2.1-6 the lugs 35 are caused to move along the cams in the slots 3st so as to rotate the SPI'OChIUtS to a limited extent. This limited rotating ot' the sprockets is designed in agreement with the illustrations of Figs. & and 6, as er-tplained above, so that the vanes may be moved ton ward or rearward to such an extent that: wind has no elleet upon the vanes. The design and form of the cams depends therefore entirely upon the extent to which the sprockets have to be turned or moved to assure a neutralizing. Any number of vanes can be controlled in this manner, though four have been indicated in the drawings as described above.

Though two coupling members each on the opposite ends of the sleeve 28 as indicated at 29 and 32, it must be understood that this too is merely a matter of detailing, and it may actually be found more practical and convenient to provide only one coupling JllOIlilJtLUttCll on the opposite ends, so as and in order to avoid mistakes in setting the vanes in their relation to the main arms It"? and the main wind-wheel, since, with two coupling members it might be possible that the vanes be set unintentiomilly to reverse the moremel'lt of the wind-wheel.

.llaving thus described my invention, I claim:

it. in a windmill, in combination with rotatory vanes and their controlling means including sprockets, gears to transmit 17otating motion to the sprockets, and cam-like engaging members between the gears and the sprockets whereby the sprockets may be set to and held in inoperative position so as to control said vanes in a similar manner. :3. lln a windmill, a wind-wheel mounted on a main shaft and carrying rotatory vanes,

a sprocket drive between the main shaft and the vanes, and canelike engaging means between the main shaft and the sprockets whereby the sprockets and therewith the said vanes may be moved to and held in inoperative position.

3. In a windmill, a wind-wheel mounted on a main sha it and carrying rota tory vanes. a stationary sleeve mounted on the main shalt, gears pivotally mounted on the stationary sleeve, another gear firmly mounted on the main shaft to transmit the motion "from the shaft to the first-named gears, au other la r turuahly mounted on the stationary sl eve operatively engaged with the tirstnamet'l gears, a second sleeve tinrnably and shi-itahly mounted on the stationary sleeve, and a sprocket-wheel-earrying sleeve turnably and shi'ltably mounted on the last:- nained sleeve, the second and third-nanuul SlGEfVtlr? having *am-like inter-engagements whereby the sprocket and thereby said vanes can be moved to and held in inoperative position.

in testimony that I claim the foregoing as my invention I have signed my name.

JOHN OTOOLE.
