WINIDMILL.

Application filed J-uly 21,

This invention relates toa wind mill, the

general object of the invention being toi of the mill.

This invention also: consists in; certain other features of constructionand in the. combination and arrangement of the several parts, to be hereinafter fully described, illnetrated' in the accompanying drawings and specifically pointed out in the appended. claims.

In describing my invention in detail" reference will be had to the accompanying drawingswherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is. an elevation of the apparatus, with the parts in inoperativeposition.

Figure 2 is a, view taken at right. angles: to Figure 1 Figure 3 is: a section on line 3-- ure- 1.

Figure 4 is a section on line of Figure- 2.

Figure 5. is a section on me at.

. Figure 7 me 6.

In these views, 1- indicates the: tower which is mounted upon the base 2, and 3 indicates cap which is connected to the top of the tower. The cap. has-its top nacemachined to. engage the machined: lower face of: a turntable i so that the tinrr table can have free rotary movement on the cap. The cap. is: provided with a: depending boss at't-he center, through which a-sleeve- 6 passes, said sleevedependingfrom the table at, a collar being fastened to the sleeve by a bolt 8 and engaging the-lower end of the of Figline-5+5. of

is a section on line 7-7 of Figt bossto hold the turntable on the cap. Said table carries the bearingst) for the horizontal shaft 10 toiwhich-thespider 1 1 of 1926-. Serial No. 124,071;

the, wind Wheel 12 is: fastened; A flanged member 13; is attached to-the outer end of the shaft 110 and guy wires 11% extend from the member/13; to;- thewheel to make the wheel very rigid. This shaft 10 has: beveled gear: 135 secured thereto, which is designed to mesh with a similar gear 16 fast,- ened to: the end ot a. vertical shaft lZ which passes through the sleeve 6 and throughbearings in the, lower part of the apparatus.

This shaft. 1-7 is vertically movable through means; of an; eccentric; shaft 18.journaled in a small casing 19' resting on the base 2 and socket member 20 which receives the lower 1 end 013 the shaft 17; and is. moved vertically by theeccentric shaft through means of the shoe 21 which is; arranged between thesecentric shaft and the socket meinben. beari-ng22 is located in the lower end of the socket and forms a thrust: bearing for the shaft 1 5., A weighted arm 23 .is con:- nected? with the eccentric shaft 18' for rocking the same. These parts are. so arranged that when the arm has been moved to its? limit of moneinentto one side of the, casing,

thepazrts willbe ina.positionwiththe shaft 1 4 in) its: lowest position and when the arm 23 has been swimg over to the other limit of rtsjmovementg the parts Will be in raised positiom --l he upper end of theshaft 17 engages a lever 25L. which is pivoted intermediate its ends to; the turntable and. the outer end of saidleveris connectedby. a chain 25 with a weighted latchlever 26; which is pivoted intermediate its ends to an upright 27 formed at one end of abridge piece 28 which'is carried by. the turntable and which bridges the shaft 10. This latch lever is designed; to lock thev'ane or rudder 29 to, the .turntable, the arm 3010f the vane being pivoted; to.- the vertical shaft 31 extending upwardly.- from the bridge. \Vhen. the lever 24 is rocked bythe upward?movement of the shaft" 1 7),. it 'will move the latch lever 26 e to releasing position through means of the chain 25., Theweight on the end of the latch lever'will return the parts to. normal position. when the shaft 17 is lowered.

The turntable is, formed, with a ring gear 82 with which meshes a; pinion which. is fastened to the upper end oli a vertical shaft 34 having its upper end journaled in a part of the cap and its lower end in a cross piece 35 carried: by the tower.

, Thel'ower partof theshaft 3% has: fastened thereto a gear 36 which meshes with a gear 37 carried by a crank shaft 38 journaled on the cross piece 35, the handle of the shaft being shown at 39. Thus by turning the shaft through means of its handle 39, the shaft 34 will be rotated to rotate the turntable.

The turntable is locked against move-. ment through means of a slide 40 arranged in a guideway 41 formed in the cap and having teeth 42 for engaging some of the teeth of the ring gear 32. A stem 43 is fastened to the slide and a spring 44 on the stem tends to move the slide upwardly to cause its teeth to engage some of the teeth of'the ring gear. A chain 45 has one end connected with the stem and its other end connected to a rock shaft 46 which is journaled in journals on the cross piece 85 and this shaft has a weighted arm 47 attached to its outer end for moving the shaft to cause the chain to pull the slide downwardly or to slacken the chain to permit the spring to move the slide upwardly. The movement of the shaft 17 can be transmitted to machinery to be driven through any desired means.

From the foregoing, it will be seen that when the vane is held locked to the turntable by the latch lever, the wheel will be parallel with the vane, as shown in Figures 1 and 2, and if the turntable is free to move, the wind, acting on the vane, will hold the parts with the wheel and vane parallel to the air currents and thus the wheel will not be rotated by the wind. WVhen the device is to be thrown into operation, the lever 23 is swung over so as to lift the shaft 17 and thus move the lever 24 to release the rudder or vane from the latch lever. Then the handle 39 is rotated to rotate the turntable tomove the wheel into the wind, after which the lever 47 is swung over to permit the spring to move the slide 40 upwardly and thus lock the turntable in adjusted position. :The wheel will then be rotated by the wind so that the shaft 17 will be driven and thus the machinery, which is connected with the shaft, will also be driven. When the device is to be rendered inoperative again, the slide is lowered to unlock the turntable and then the turntable is rotated until the latch lever again engages the rudder, the shaft 17 having first been lowered to permit the latch lever to move into locking position.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims,

What I claim is 1. A wind mill of the class described comprising a tower, a driven shaft journaled therein, a turntable rotatably mounted on the topof the tower, a horizontal shaft carried by the turntable, gears connecting the two shafts together, a wind wheel carried by the horizontal shaft, manually operated means for rotating the turntable, locking means for locking the turntable in adjusted position, manually operated means for actuating the locking means, a vane pivotally supported on the turntable, a weighted latch lever on the turntable for holding the vane parallel with the wind wheel, a lever pivoted to the turntable, a flexible member connecting the lever to. the latch lever and means for moving the driven shaft vertically to move the lever to a position where the flexible member will move the latch lever to releasing position.
