WINDMILL.

Application led March 25, 1924. Serial No. 701,720.

[o all w/Lom t may concern:

Beit known that I, DANTEL R. SoHoLns, a citizen of the United States, residing at Chicago, in the county of Cook and the State of Illinois, have invented a certain new and useful Improvement in Windmills, of which the following is a full, clear, concise, and exact description.

My invention relates to windmills. In one of its characteristics, the invention resides in an improved bearing for relatively rotating parts of the windmill. In another of its characteristics, the invention resides in the provision of means for protecting relatively movable parts from the weather.

rIhe invention is of particular service in connection with the windmill shown in the patent issued to La Verne Noyes, December 14E, 1915, No. 1,163,682, though the invention is not to be limited to such employment.

The windmill of the aforesaid patent coniains a furling device that is inclusive of a manually adjustable vertically reciprocable nonrotating sleeve that surrounds a stationary upright column, a collar rotatabley upon and vertically reciprocable with said sleeve, and linkage between the collar and the mill vane whereby the vane may be folded toward the wheel when the wheel is to be placed out of the wind. In northern latitudes the collar of such a windmill was apt to be frozen against movement, in cold weather. This was due to the wide access that existed to the collar. In carrying out my invention, the vertically reciprocable nonrotating sleeve carries an annular hood which overhangs the collar in a manner to direct rain and snow away from its interior. T he collar, in turn, carries an annular hood which guards against seepage to the sleeve.

In the preferred embodiment of the invention, the portion of the sleeve which is overhung by t-he annular hood upon the collar is in the form of a rim of an annular lubricant. receiving trough that preferably merely rests upon the sleeve, the trough being in effect, a port of the sleeve as the trough is not normally movable with respect thereto, due to the friction between the bottoni of the trough and the engaging adjacent horizontal end face of the sleeve. The collar is seated upon the bottom of the trough which, with the oil or other lubricant in it,

constitutes an antifriction step bearing for the collar.

The invention will be more fully 'eX-r plained in connection withtheaccompany ing drawings showingone type of windmill equipped vin accordance with the preferred embodiment of the invention. Fig. l is a view, in elevation, of 'such a windmill; Fig.

l p l i 2 is a sectional view on line 2-2 of Fig. 1; p

Fig. 3 is a sectional view on line 3-3 of Fig.

1; Fig. l is a view, oni a larger scale, of a part ofthe structure appearing in Fig. 3; and Fig. 5 is a sectional view on line 5--5` of Fig. et.

Like parts are indicated by similar char# lacters of reference throughout thedifferent figures. Y

The wind wheel 1, vhaving a horizontal axis, is mounted upon a shaft lwhich 'carries spur pinions in' mesh with spur. gears 3 that operate pitmen 4 having connection at their upper ends with the load rod 5. The wind wheel is mounted upon a mill head 6 which vis afforded an upright axisl of rotation by being mounted* upon the' shouldered end of a stationary vertical column in the form of a pipe 7 at the upper end of the mill tower and through which pipe the load rod passes.`

The mill vane 8 is jou'rnaled at 9 upon the mill'head to swing about an upright axis, the vane being moved toward and from the wind wheel when the latter is respectively to be placed out of and4 iii the wind, spring buffers 10 cushioning thepvane in the nal portions of its swinging movements.

A swinging arm 1l is afforded an upright axis of'movement by lbeing mounted upon a vertical bearing shaft 12 fixed upon the mill head with the load rod between and preferably substantially equidistant from the mounting shafts 9 andI 12. The long branch of arm 11 is flexibly connected with onevend of link 13 whose other'f'end moves a finger 13.', operatively forming a part of the link, which operates to engage and move the vane toward the wheel inthe furling operation, but from which finger the vane may move toward the wheel in governing. A lever rod 14 connectsa` vertically movable furling collar lwith the arm 11 near the connection of said arm with link 13, which link" is `also preferably `a rod. The vane operation,V link'13 pulls' upon one endl' of arm 8 and rod 16 pushes upon the other end of this arm to cause linger 18 to push the vane 8 to a closed position. The lower ends of lever rods 14e and lfarebent to extend horizontally there to be journaled in horizent-a1bearings-17formedfontopof the furl-` ing collar 15 and on opposite sides of its' aX- is andlequidistantly from its center. The col-larV 15 is in assembly witha sleeve 18 (loosely surrounding pipe having connection with the upper ends of Vpush rods.

19 whose lower ends are connectedwith one end of alever 2U whose other end. carries agpullwire 21 accessible from the ground.

Thecollar 15 and the rods" llluand 16I 'will turn with thehead and with refer-'ence tol sleeve 18 which is onlyy vertically movable. When the wire y2'1fis pulled downwardly (after which action it is hooked at its lower or ground end) ,the rods 19 are consequently pushed upwardly tovcause the sleeve 18 to push the furling collar up, to swing the mill vane from Vits position when the wheel isir the wind yto aposition ingwhich the wheel isout of. the wind.; The furlino'A collar has a tubular continuation or elongation 15" and its supportingsleeve has a tubular elon tion'18. within and extendinglupwardly eyondfthe elongation y15VJ both` elongations surroundingfthe column 7. The sleeve continuation prevents. the sleeve from gripping the column. The collar isradiallyandhorizontally'extended 'beyondfthe horizontal or shoulder portion of the. sleeve, as indicated.

at 152. lAn inverted. annular channel 153, constituting a hood, is formed around'and in the bottom of, the collar.4 The bottomportion of the collar between this channel and the bore ofthe collar is received in an.

annular trough 2'2which surrounds`- the c olumn This trough may be *substantially stationary by havingfrictional engagement withI the sleeve 18: upon the horizontal or shoulder portion ot which the trough rests. By. reason of ther oil vor other lubricant in the trough such trough isconstitutedan ani y tifriction` stepb lor endy thrust bearing` for the' collar and the load." upon thek collar. The outer .peripherally grooved hood portion 153 of the collar'cooperates -with the outer annular rim of the trou'ghto prevent seepage of moisture inwardly between the collar and its bearing and between the col- .lar and the sleeve'. The inner annular rim of the trough guards against the outwardy horizontal seepage-ot' moisture 'between the collar and itsA jdirect support-the bottomot the trough. Downward seepage ofV moisture to the support for the collar is guarded` .fro'm` the trough within the collar against by the annular hood 23 which is carried by the sleeve and is curled outwardly over and receives the upper end of the upright collar extension 15. This hood has an upright downwardly extending tubular' continuationv28 vwhich 'surrounds theupwardlyextending" upright tubular continuation 18 of the sleeve, and is surrounded by theU upwardly extending upright tubular continuation 15 oit the collar. The hood 23 and its said 'eXtension are spaced apart from the upright collar portion 15 and the upright vsleeve portionlS" to afford ample clearance permitting lrelative movement between the collar and sleeve. The sleeve is laterally spaced'apart from the column to permit-movenientotu the sleeve and the parts drawings. and description which have been furnished.

lt is obviousthatlfchanges may be made without departing from the spirit of ,my invention. Y Having thus described my invention l claim as new and'idesire to secure by Letters Patentthe followingzy 1; urling mechanism for a windmill vane that has an upright column and a head mounted to yturn upon the column, includingwa rotatable collar in furling connection with thevane and surroundingthe column andan annular trough also surrounding the colunnand` upon whose bottom the collar is supported; and a hood united with the inner rim ofthe trough andextending upwardly from the trough within the collar and thence outwardly over the' top o1 the collar.
