WINDMILL WHEEL.
APPLICATION EH-ED 0:0.21. 1918.

mamas rjrrcxn'rr, or Mammy-mesmeri- 'WINDMILDWHEEL. I
Application filed December 27, 1918.- 'Seria1'No. 268,528;'
To all whom it may concern? V Be it known that I, STERLING Pl P1 Kn'r'r a citizen of the United'Sta-tes, residing at Madison, in the county of Monroe and State of Missouri, have invented a new and useful ll iudinilliWheel, of which the following is a specification.
it is the object of this invention to provide novel but simple means whereby, in a high wind, the blades of awindmill will be caused to feather and spill the wind, the construction being such that the device 'Wlll adjust itself automatically to the velocity of the wind, means being provided whereby the blades may be set to feather at any predetermined wind velocity. I
It is within the province of the disclo sure to improve generally and to enhance V the utility of devices of that type to which the invention appertains.
lVith the above and other obJects 111 v1ew,
' which will appear as the description, prowindmill wheel, the frame comprising a hub coeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be madewithout departing from the spirit of the invention.
In the accompanying drawings Figure 1 shows, in side elevation, a poition of a windmill wheel embodying the in vention; Fig. 2 is a fragmental top plan of the wheel, Fig. 3 is a radial section of the wheel, parts appearing in elevation; and
Fig; 4 is a section taken through one of theblades and attendant parts. V Referrmg to the drawlngs the numerall denotes a shaft, carrying the frame of a 2 from which U-shaped spokes 3 radiate, An outer rim 4 is carried by the bends of the spokes 3, and a rim 5 is secured to brackets 6 mounted between the side portions of the spokes 3. Blades 7 are provided, the
inner ends of the blades being pivoted, as shown at 8, to the inner rim 5. The blades 7 have openings 9 through which the Quten rim 4 passes. An angle member 25 is secured to each blade 7 and projects into the opening 9, the angle members, 25 being united by meansof pivot elements 26' with the outer rim 4. Reinforcing strips l0 are secured to the blades 7 and extend transversely thereof.

Thea strips :10? terminate in bearings 11, re ceiv-ing, .:pivotally,' angular lingers 'l4forined at the ends of intermediate links 12. One bearing 11 on the blade 7 which is nextto thevspoke 3 receives pivotally a finger 17 on one end of a-terminal link 18 pivoted at 19 to the outer end of a radius rod 67, the inner endof the radius rod being pivoted at 68 to one of the spokes? Ashaft 63 is mounted for rocking movement in the spoke 3 and includes an arm 64 and an arm 65, the arms being located on opposite sidesof the spoke 3. The arm 65 terminates an extension 100 mounted for limited reciprocation. ina longitudinal slot is adjustable along'the arm 6% of the shaft 63 and is held inadjusted positions by a set screw 72. Thearm 64 carries a hanger 73 whereuntois connected the outer end of a retractile spring 74, the inner end of the spring 7l being assembled with an eye bolt 7 amounted adjustably in a bracket 76 carried by the spoke 3, A nut 77 is threaded on the eye bolt 7 5 and cooperates with the bracket76 to adjust-the eye bolt 7 5 1ongitu- 'di'nal'lyfand,consequently, to vary the tension of the spring74. V
lVhen the-windmill wheelspeeds up unduly, the weight 71 causes the shaft 63 to rock, the arm (i5 being actuated, and the part 100 Ofthe arm movin'gcin the'slot 66 v of the radius rod 67, the radius rod 67 tilting onits, fulcrum 68, and the terminal link 69 being operated to shift or feather thejblades of the windwheelr V Generally considered, the construction of the device issuch that'it will automatically feather the blades of a wind mill wheel, and
prevent the wheel from being blown to pieces or damaged, in a high gale. It is possible to vary the tension of the controlling spring, sothat the blades will feather at locity which the judgment of the operator Iclaim: I i l .1'. A windmill comprising a frame; ablacle pivotally supported on the frame; a rock shaft disposed transverselvof the frame and provlded with arms; acweight on one arm;
frame; means for pivotally connecting the outer end'of the radius rod with the blade; and a lost motion connection between the other arm of the rock shaft and the radius rod. I
any 've- 66 formed in the radius rod 67. A Weight 71 a radius rod pivoted at its inner end to the 1 2. A Windmill comprising a frame; a blade pivotally supported on the frame; a rock shaft disposed transversely of the frame and journaled therein, the rock shaft having arms; a radius member pivoted at its inner end to the frame; means for pivotally connectingthe outer end ofthe radius member With the blade; a lost motion connection between one arm of the rock shaft and the radius. member; a Weight adjustable along the other arm of the rock shaft; means for said "arm; and a retractile spring having its ends connected, respectively, to the Weightrarryinp; arm and to the frame.
In testimony that I claim the foregoing; as my oWn, I have hereto affixed my signature in the presence of tWo Witnesses.
