WINDMILL.

Application filed May 5,

This invention relates to windmill structures and pertains particularly to an improved construction of top structure. The primary object of this invention is the provision, in a manner as hereinafter set forth, of a windmill superstructure having an improved means for rotatably supporting the sails and vane of the structure.

I The intention contemplates the provision of a relatively large flat annular structure supported wheels which are pivotally mounted at spaced intervals about the periphery thereof and which run upon the top 7 of aplatform, forming a part ofthe windmill top structure. Upon this revolving annular structure a shaft is mounted which carries the sails and diametrically opposite the end of the sail carryingshaft, there extends the wind vane by means of which the moving structure is held in the wind or made to move transversely thereof or to be held stationary at-fthe option of the user. A vertically reciprocating shaft which eX- tends upwardly through the windmill structure projects through the center of the annular revolving structure and has an eccentric connect1onwrth the sail carrying shaft,

by means of which the rotary motion of the shaft is translated to a vertical reciprocatory movement.

The invention has for another object a windmill super-structure of strong and durable but simple construction, having few moving parts to getout of order or be re placed and comparatively inexpensive to manufacture and set up. I v

The invention will be best understood from a considerationof the following detailed description taken in connection with the ac bonipanying drawings forming a part oft-his specification, with ,the understanding that the invention is not confined to any strict conformity withthe showing of the drawings but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claim.

Inthe drawings Figure 1 shows the structure embodying this invention and in side elevation, .with the ropes controlling the wind vane connected I ture.

with the supporting and holding devices therefor.

Figure 2 Figure 3 is a fragmentary elevation of the structure looking from another side.

Figure 4 is a. view of the underside of the platform at the top of the windmill frame.

Figure 5 is a sectional view taken transversely of the platform and the revolving structure which rests thereon and,

Figure 6 is a detailed perspective view of one of the arms carried by the revolving structure, which acts as a rope guide for the control of the vane.

Referring now to the drawings in detail wherein like numerals of reference indicate corresponding parts throughout the several views, there are indicated by the numerals '1, a frame having four standards which are in upright slightly convergent relation as shown and which form the supporting beains'for the windmill superstructure. Overlying and fixed to-the upper ends of the beams or stand ards 1, by means of the securing brackets 2, is the platform 3, the same here being shown as of circular design and having a central aperture 4 therethrough. It is of course understood that this platform may be square or Figure 3.

The central portion of this beam 5 has a bearing 6 extending therethrough, which hearing has a plate 7 connected to one end vthereof which plate is secured to the underface of the beam 5 as shown in Figure 4-; The foregoing described structure forms the permanently stationary portion of the windmill structure. r i

The movable portion of the superstructure comprises an annular member 8 having thecentral aperture 9 therethrough and this member is positioned in superposed relation to the platform 3.

A plurality of brace arms 10 are arranged overthe moving structure 8 the lower end of each'arm being angled to provide a foot is a top plan view of the strucj ill ill

11 which is secured by means of the bolts 12 to the moving member. 'llhe upper ends of these arms converge to and merge with a central plate 13 which is arranged directly over the bearing 6 and has an aperture therethrougrh in alignment with the said bearing. The arms as shown, thus set up a pyramid shaped structure over the central opening or well 9 ol? the rotatable member 8.

The ends ot the foot portions 11, are extended outwardl; beyond. the periphery of the member 8 and turned downwardly extending; a substantial distance below the underlacc thereof as shown in l grures l. and These downturned portions 13 oi the foot members ll, each has secured thereto by meai'is at the stub shalt at. the supporting wheel 15. As is clearly shown in Figures 1 and 5. the-3e supporting wheels run upon the top oi the platform 3 and support the struc lure 255 and adjacent elements. over the platiiirri'n.

jltstcndil'ig up 'ardly through the wind mill structure and through the bearing 6 and the plate 13, is a vertically rcci nm-able pump oiierating' rod 16. The upper portion of this rod 16 diwctl) beneath the plate 153. has a collar 1i" secured thercaboiu" from which a connector 1.8 extends.

hflounted upon the revoluble member 8 is a pair of aligned bearings 19 and extending through these bearings, radially oi? the memher 8, is a shaft 20 upon the outer end of which a sail wheel, indicated gene ally by the numeral 31. is mounted. The inner end of the shalt 20 extends to a point adjacent to the shaft 16 and is operatively connected through the medium of the part 22 and connector 18, so that on revolution of the shaft 20 the pump rod 16 will be operated. The part and connector 18 construction here shown may be of anx a mropriate design suitable :tor the use herein de.-- 'ribcd.

Mounted upon the revoluble member 8, in alignment with the shaft 20 is a vane arm 2;), the outer end oi. which extends a sub stantial distance bevond the periphery oi? the member 8 and is reduced as indicated at El and is also provided with an aperture. .lfivolallg. connected to the reduced portion B l. ot the vane arm 2 the inner end of a vane 26. the portion 25 of the vane being bi'l'urcated to receive the reouccd portion 2st of the .iixed arm 23. A pivot pin 27 is passed through the fur .itions oi the portion 525 of the one and through the reduced portion i l, to pivotallv secure the same together.

As shown, the tired arm 23 is arnnged directly between two of the foot portions 11 ot the porting arms 10 and extending outwardl 'om those toot portions ll which are arranged one on either side of the arm 33, is a lined arm 28. These arms as shown, are parallel with the lined arm 23 of the tune and have their i nncr ends secured to the member 8 by means of the bolts 12 which pass through the adjacent foot portions 11, which bolts extend through the turned ends Q9 of the arm. The outer portion of each of the a runs 28 extends inwardly at right angles as indicated at 30, toward the vane arm 23 and there is then formed a loop 31 at the inner ends of these interned portions which loops merge into downwardly extending drop portions 32 which terminate at their lower ends in the double hook 33. The two structures covered by the reference numerals 29 to 233, constitute vane controlling: rop simportingr and holding elements.

Upon each side of the vane body 26 there is secured an eye 34!: and from each of these ev there extends a control rope 35 which pas... s through the ad acent loop 31 01'' the structm'e above described. These ropes are then extended downwardly and passed through the double hook structure which due to the manner in which the rope is threaded therctln'ough, forms a frictional re sistance to the easy slipping of the rope to maintain the same fast at adjustment thereof to set, and regulate the position of the wind vane. As is shown in Figure 1 the depending or drop portions 32 of the rope holding structures extend a substantial distance downwardly in parallel. relation and the ends of the rope are trained about the hooks and secured at adjacent points to the same. It will be readily understood that when the vane 26 is held in the manner shown in Figure 1, by means of the control ropes 35, that the sail wheel will be held in the wind and the windmill will operate. In order to throw the sails out of the wind, the ropes 35 are continued from the hooks 33 to the securing eyes 36 and one or the other thereof pulled to swing the vane in the desired direction whereupon the ropes may again be secured to the eyes 36 to hold the vane in the set position in which set position the sails 21. may be partly or completely out oi the wind to reduce or stop the operation of the mill and prevent the superstructure from rotation upon the support, as is clearly shown in Figure 3 of the drawing.

From the foregoing description it will be readily seen that an improved windmill super structure has been set up which will be light and easy to operate, yet strong and durable and e'llieient in action.

Having thus described my invention what I claim is:-
