WINDMILL.

Application led May 16, 1914.

T0 all whom t may concern Be it known that 1, WILLIAM WEINER, a citizen of the United States, residing at Guymon, in the county of rleXas and State of Oklahoma, have invented a new and useful TWindmill, of which the following is a specication.

The device forming the subject matter of this application is a windmill, and one object of the present invention is to provide novel means whereby the blades of the windmill may, through the medium of a simple structure, be permitted to feather, and through the instrumentality of the same structure, be swung into inoperative positions.

1t is within the scope cf the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

1n the accompanying drawings: Figure l shows the invention in side elevation; Fig. 2 is a top plan; Fig. 3 is a fragmental top plan showing one of the blades swung into an 1noperative position; Fig. 11 is a fragmental horizontal section showing in top plan, a mechanical movement which may be employed in connection with the windmill herein disclosed; Fig. 5 is a fragmental horizontal section showing in top plan the lever whereby the blades of the windmill are controlled; F ig. 6 is a fragmental side elevation showing in detail the connection between one blade and its actuating lever; and Fig. 7 is a perspective of the connection.

1n the drawings there is shown an upright frame 1 of any desired sort provided at its top with a supporting` plate 2 and equipped adjacent its lower end with a thrust bearing 8. Journaled for rotation in the supporting plate 2 and upheld by the thrust bearing 8 is a vertical shaft 3 equipped near its lower end with a wheel el provided with upstand ing pins 5 carrying rollers 6 mounted to move within an open head 7 formed in a Speccaton of Letters Patent.

driven member 9 fulcrumed on a post 10 carried by a bracket 11 on the frame 1. By means of a link 12, one end of the driven member 9 is operatively connected with an upright bell crank 14 fulcrumed on a standard 15 supported by the 'frame 1. rllhe outer end of the bell crank 14 is connected with the pitman 16 of a pump 17.

Noting Fig. l it will be understood that each time that the wheel d is rotated through the medium of the shaft 3 two strokes will be imparted to the driven member 9 through the medium of the pins 5, motion being transmitted by means of a link 12 into the bell crank 14 and thence into the pitman 16 of the pump 17. 1f a single stroke only is desired at each revolution of the wheel 4:, then one of the pins 5 is removed. Further, by removing both of the pins 5, the element 4 may be used as an ordinary band wheel for driving machinery of any sort.

Passing to the windmill construction which forms the subject matter of this application, it will be observed that a spider 18 is attached to the shaft 3 above the supporting plate 2, the spider 18 carrying arms 19. r1`he spider 18 and the shaft 3 may be described as a rotatable frame.

1n order to simplify the drawings, four arms 19 only are shown, but it will be understood that any desired number of arms may be employed. Mounted on each arm 19 adjacent its outer end is an upright stud 2O upon which is pivoted for horizontal swinging movement a blade 21. 1f desired, guys 22 may extend from the upper end of each stud 20 to a cap 23 secured to the upper end of the shaft 3. 0n the side face of the blade 21 is a bracket 2li receiving pivotally an eye 25 formed at one end of a lost motion Connection 26 permitting a feathering of the blade 21 and having a shoulder 27 and provided with a terminal Enger 28. That portion of the connection 26 which lies between the shoulder 27 and the nger 28 is mounted to slide in an ear 29 formed on one end of a lever 30 fulcrumed as indicated at 31 for horizontal swinging movement on a support 32 outstanding from the arm 19 and constituting to all intents and purposes a part of the arm. The blade 21 and the lever 30 may be described as cooperating elements, the connection 26 being pivoted at 25 to one of said coperating elements and being mounted to slide in the other of said cooperating elements. By means of a link 33, the inner below the supporting plate 2.

end of the lever 30 connected with a bell crank lever 34 fulcrumed for vertical swinging movement as shown at 35 upon the arm 19.

In order to control the several bell crank levers 34 a slide or actuating element is tions 37, the disk 36 is united with a sleeve 38 mounted to slide vertically on theV shaft 3 A compression spring 39 is interposed between the arms 19 at their point of intersection, upon the one hand, and the disk 36. The tendency of the spring 39 is to elevate the disk 36, and the sleeve 33.

As will beunderstood best from Fig. 5` when this figure is compared ywith sundry other figures of the drawings, a lever 40 is ulcruined at one end upon the frame 1, as shown at 41, the lever 40 extending around the sleeve 3 8` and engaging the lower portion of the sleeve to eect a depression of the sleeve and the disk 36. By means ofv connection 42, theY lever 40 is united with a lever 43, fulcrumedas shown at 44 on the frame 1. The free end of the lever 43 may be swung downwardly and be engaged beneath a pin or like projection 45 on the frame 1.

When the windmill is running,` the blades 21 stand out from the ends of the arms 19; in alinement with the arms as shown in Fig. 2. Under such circumstances, the

v shoulder 27 on the connection 26 abuts againstjthe ear 2 9 on the lever 30. The bell crank lever 34 moves in a plane at right anglesto the plane of movement of the lever 30 and consequently the link 33, coperating with the bell crank lever 34, prevents the blade2i from swinging, under thepressure of the Wind, beyond the outstanding position shown in Fig. 2. When, however, the wheel has rotated sufficiently, so that'the win df `pressure is brought against theY rear face 1 of any blade 21,A *such blade will be permitted to feather slightly, the connectionr26 sliding in the ear 29.01 thek lever 30 until the' iinger 28 on the connection engages the ear.y Obviously, owing to this feathering operation, the wheel will rotate. readily and with a minimum expenditure of wind pressure.

Now when it is desired to dispose the` blades 21 in inoperative positions, as shown in Fig. 3, the lever 43 is pressed downwardly and its free end engaged beneath the pin 45. The connection 42' is drawn downwardly, the lever 40 is tilted, the sleeve 38 is depressed, and by means of theconnec-v tion 37, the disk 36 is depressed, the spring 39 being put under compression. When the disk 36 moves downwardly, the same will engage the inner ends of the bell crank levers 34, tiltingY the bell crank levers on their fulcrums 35and imparting movement to the f rlevers 31 through the medium of the links 33;' 4When the levers 30 are actuated, the

years 29 on the levers yengaging the shoulders 27 of the Vconnections 26 will Vswing -the bladesv 21 inwardly into the inoperative positions shown in Fig. 3 of the drawings.l The wheel now will not rotate readily fortwo reasons. First, because the blades 21 have been swung inwardly to such an extent that their centers of. eifort have a relatively short.'

power ann; and Secondly, beoanSe the disk;- 36, hearing upon the inner endS of ihelevero 34 will'tend to act as a brake. As soon 'as the preSSnie of the, dislrdo on the inner ends of the bell lorank levers'34y is released, the

Wheel Will-begin to; rotate Slowly, and, alti.` mately, ander the wind pressure, the blades` will be Swans outwardly into. the poSiiionS shown in Fig.v 1, whereupon the wheel will at once begin to rotate rapidly.
