To all whom t may concern:

Be it known that I, GEORGE W. GnN'rRY, a citizen of the United States, residing at Yeager, inthe county of Hughes and State of Oklahoma, have inventedv certain new and useful Improvements in Vindmills, of which the following is a specification. p

This `invention relates to wind'wheels of the horizontal type and has for its vobject the provisionofnovel means for throwing` the wheel into-or out of the wind, The invention' valso seeksv to provide means forfa-A cilitatingthe lubrication'or repairing ofthe wind `wheel and also seeks to provide novel means for utilizing thepower generated' byl ythe wheel. Ihe invention'is illustrated in the accompanying drawings yand will vloe hereinafter fullyset forth.

In the drawings- Figure 1 is a side elevation of a windY wheel embodying my present 'f improvements; f l

Fig. 2 is a plan view of the wheel and the parts Y(zo-operating directly therewith; i

Fig. 3 is a detailY perspective View of the shield andthe tail vane; v

Fig. 4 v,is van enlargedvcrtical section on the line 4.--4 of Fig. 1; and

Fig. 5 is a detail perspective view of a bracing flange or spider provided at theupper end of the stand pipe.

In the drawings, vthe reference rnumeral 1 indicates a concrete or similar base or foundation which is laid at the point where the wind wheel is tobe set up. Upon this base or foundation, I erect a frame=2 supporting venient or preferred manner and isvillus# trated as fitting within a flange 5 on the platform and resting on ball bearings. *A similar iiange 5 is'provided on the under side of the'platform. Adjacent the upper extremity of the stand pipe, I provide a flangeA or spider 6, 'from the edge of which lugs 7 depend and in thesaid lugs I secure the upper ends of guy wiresSwhich diverge downwardly and have their lower endssecuredto stakesor other anchors 9 Vin the ground. As Vindicated at 10, tnrnbuckles may be interposed inthe guy wires so kthat the properl tensionvmay beplaced upon the wires to hold the stand pipe against all ver-` tical oscillation. At intervals in theheight of the stand pipe,'I secure'thereto thesteps l 11 to permit aworkmantoreadily reach'the top of the stand pipe when lubricatiomiadf justmentorlrepairing ofk thewheel or the parts Vco-operatin,( j directly therewithl may be needed. The uppermost step. 121s made? 'U somewhat larger thanthe lower steps and .is reinforced by a brace lrextendingl therefrom to thestandpipe so thatitheworkman-1V may stand upon the upper step whilexper forming the necessary workn vAll the steps are providedV with split collars lswhichare secured firmly about the stand pipe by bolts, indicated at 15, inserted through their-split portions. The brace terminates` insucha split collar and an eXtra step V13 projects' from said' collar Vat the opposite'sideofthe ystand pipe-sothata firm footing' forthe:

workman will be provided. It will also' `abe noted that the uppermost step 1.11 below1 the brace 13 is close to the brace, thisarrangement being la pronounced conveniencel in actual practice. Above the'V spider' ouflange 6,-the stand pipe is yreduced to provide an annular shoulder or bearing 16 upon which is supported a turntable V1'? V'havingfavertically disposed hub 18 which Vencircles the standV pipe,.as shownmost clearly in Fig. 11.7 The bearing' provided by the shoulderl' maybe a plain bearing, or -it may beequipped with balls lor other vanti-frictiondevices Yas may" be preferred, and it is to be understood.` that throughout the enti-re"mechanisn1 all:` bea'r- V Y ings may be plain lor. anti-.friction Aas' may be desired. projecting radially therefrom is-thel lower arm 19 of a shield-carryingv frame,` thelouter.- end of'saidvarm 19 being connected by a verticalabridge memberv 20 with the outer` Secured to .the turntableandVV end of the upperVV arm 2.1vwhicl1 is similarr .1'

in all Vrespects to the said arm 19; .Y TheV upper Varm 21 is secured -to the upper side of a frame 22 which is arranged at a right p angle tothe arms 19 andA 21` and hasits lower side secured lupon theturntable 17, as clearly shown in The vlower vside of this frame is splitorddivided to accomni0 V date the hubl ofthe turntablefas -shownat 2,3, and the frame may conveniently vbe Aformed from a flat bar orfmetallie strapa having its upperand lower sides connected by vertically Vdisposed end portionsj21 To one end'portion21ofthe frame -22andfto v the vertical end? member y20,'fIseciire"ftheshield which consists of a plate of sheet metal or other material having an arcuate form and having its upper and lower edges diverging inwardly, as shown at 26,'whereby the wind currents striking the shield will not only be prevented from acting directly upon the vanes of the wind wheel but will also be deflected upwardly and downwardly so that they will be caused to flow above' and below the wheel without affecting the movement of the same. lt will be readily noted from an inspection of the drawings that the members 24 and 2O are located at or very near the ends of the shield so that the shield defines an arc of about ninetyT degrees and, therefore, encircles one-fourth of the wind wheel. The upper bar 2l ertends somewhat beyond the upper bar of the frame 22, as shown at 27, and upon this projecting extremity of the said bar 2l I pivotally attach the upper tail vane arm 28,

the lower tail vane arm 29 being pivotally.

attached to the turntable in vertical alinement with the pivot of the arm 28. The

arms

28 and 29 extend outwardly a distance approximately equal to one-half the length of the frame 22 and to the outer portions of the said'arms, I secure the tail vane 30 which will preferably be of sheet metal but may bev of other material and may be of any preferred design which will present a 'sulfcient area to the wind to effect the shifting of the vane. Extending from the pivot 3l of the lower arm 29 is a counterbalance arm 32 which is preferably integral with the arm 29 but may be otherwise unite-fl therewith. This arm 32 carries a counterbalance 33 upon its free end and a trip rope 34 is secured to the arm and extends therefrom to a guide pulley 35 on the under side ofthe frame 22 adjacent the edge of the shield 25 and thence passes downwardly to a point near the ground wherebyvit may be readily manipulated. To the arm 29 adjacent the inner end of the vane 30, I secure a trip rope 36 which passes therefrom toa guide pulley 37 at the opposite end of the frame 22 and thence depends to a point near the ground, as will be readily understood. An extension coiled spring 38 has one end attached to the upper edge of the shield 25 and its other end connected to the upper vane arm 28 and is so arranged that it will be constantly under tension and in one position of the vane will be disposed at one side ofthe pivot thereof, while in another position of the vane will be at vthe opposite side of the pivot, as will be readily understood upon reference to the full and dotted lines in Fig. 2, so that the spring tends to hold the vane in the position in which it may be set.

The drivel shaftv 39 extends through the stand pipe 4 and is rotatable therein, the

' lower end of the shaft projectingY below the lower flange 5 and being equipped with a beveled gear 40, while the upper end of the shaft projects above the upper end of the stand pipe and has the hub 4l of the wind wheel secured rigidly thereto, the upper extremity of the shaftfitting lin the bar 21 and frame 22 at the junction ofthe same.

i The hub may be secured to the shaft in any desired or preferred manner and l have illustrated a bolt 42 inserted diametrically as to possess the requisite strength and durability without excessive weight and theupper and lower edges of the severalblades are turned inwardly,as indicated at 45, -whereby a concave surface will be presented to the wind. Brace lrods 46 vare secured to and extend between the several blades'. so as toY reinforce the structure and to prevent coll lapse of the blades under very strong winds. Upon reference to the arrows in Fig. 2 which indicate the direction of the wind, it will be seen that the wind will strike directly upon the concave faces of the several bladesk and the impact and pressure of the wind upon the blades will cause them torswing around the stand pipe as a center and thereby impart rotation to the shaft 39. The rotation of the shaft 39 will, of course, be transmitted directly to'thebeveled gear-40 and utilized to drive various machinery. In the accompanying drawings, I have shown the beveled gear 40 meshing with a gear 4T which is disposed within the frame 2 and secured upon a shaft 48 extending through the frame and beyond the sides of the same. At one end, this shaft 48 is equipped with a pulley'49 adapted to receive a bolt which may be carried to any desired point to drive a threshing machine or other machinery At the end remote from the pulley 49, the shaftl 48 is equipped with a crank 50 which is connected by a pitman 5l with the piston rod 52 of a pump. l also show a gear 53 carried by a shaft disposed at a rightA angle to the shaft 48 and adapted to mesh with the gear 47 so that power may be transmitted' through the gear and the shaft carrying the same to any desired point. It will be understood that another shaft may be arranged in axial alinement wit-h the shaft carrying thegear 53 and at the opposite side of the shaft48, but l have not illustrated the same. lt will also `be understood that upon their respective shafts and controlled by shifting levers soithat they may be thrown into or out of operative position at will. p Y

As has been lstated and as will be readily understood upon reference to Fig. *2,the:

wind wheel is rotated bythe force of air striking against the blades or vaneset. Thevane 30 is disposed parallel with the direction of flow ofthe wind and in the'position shown in Fig. 2 will hold the shield 25 in the face of the wind so that only one-half of the blades will be presented to the wind and the resistance to the 'rotation of theY wheel which would be caused by the wind striking the convex side of the remaining blades is overcome. `V`When the wheel is. to be thrown out of Gear, the trip rope 34;V is drawn downwardly so that the arms 32 `and 39 will be swung about the pivot 3l, the arm i 28, of course, following the movement. The tail vane will thus be brought` into the position shown Vin dotted lines in Fig. 2 which is substantially .alined with the central radius of the shield 25 and the wind striking tion shown in dotted lines carrying with it Y the shield 25 so that the blades 44; lwill be again exposed to the force of thewind andV the wheel will be rotated. The arm 32and the weight 83 counterbalances the tail vane andthe shieldso thatthe movement of the devices in shifting into and out of the wheel will be easy and even. Y p

My improved apparatus is simple in construction and arrangement and may be manufactured and vset up for use at a cost which is not prohibitive and will be found highly eflicient in operation.` Y f Ha ving thus described the invention, what is claimed as new is: j
