To all whom, it may concer-n.-

l Be it known that I, GEORGE M. BEAM), of

of Indiana, have invented certain new and useful Improvements in Windmills; and I do hereby declare the following to be a full, clear, and eXact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to windmills; and it consists in the construction, combination, and arrangement of the several parts hereinafter fully described, and specifically pointed outin the claims.

It has for its objectto provide a mill wherein the attachment of the wheel to the supporting-frame will be stronger and more durable than the means of attachment heretofore employed, and whereby the shaft by which the operating machinery is driven shall be relieved from all strain incident to the weight of the wheel.

It has for its further object to provide novel means for lubrication, whereby waste of oil is prevented and a great saving thereof effected,

f of the casting.

and the necessity for the frequent supplying of oil to the cups is avoided.

lt has for its object to prevent jarring usually incident to the operation of the wheel and the crank on its shaft, thereby saving the mill from the injury sure to result from the Vcontinuation of such jarring.

In the drawings, Figure 1 is a side elevation vshowing a windmill which embodies my invention complete. Fig. 2 is a vertical longitudinalsection of the upper portion of the mill and the castings. Fig. 3 is a detail view of the spider by which the mill is centered-in position. Fig. 4 is a detail sectional view.

' Fig. 5 is a perspective of two of the adjusting-plates shown in their proper relation to each other. Fig. 6 is a detail view showing the bearing for the wheel placed to one side Fig. 7 is a detail showing the crank attached to one end of the shaft and the wheel to the other. Fig. 8 shows the cuit' on the lower end of the main tubular shaft.

Vbearing C', as shown.

Fig. 9 is a detail of the disk which is interposed between the cuff and main shaft, and Fig. 10 is a detail section of the hub of the wheel. Y

The tower or derrick A and the cap B are of usual construction and Yadapted to support the mechanism of the mill. I employ two principal castings or frames, C and D, adapted to carry the vane and the wheel, respect` ively, and which are united together so that each can turn sidewise independently of the other without deranging or displacing any of the other operating parts. For convenience, the frame C is called the vane-casting77 and the frame D the wheel-casting.

The vane-casting@ has the arm of the vane F bolted to it, and it has its upper arm provided witha bearing, E, and its lower arm with a bearing,` C, for the purposes hereinafter explained. Depending from the bearing C' is the main vertical tubular shaft G, which may be cast integral therewith orhave its end fixed therein, so that it turns with the vaue-cast ing. Projected above the bearing C is a tubular extension, G', on which is journaled the lower end, D', of the wheel-casting. This extension may be cast integral with the vanecasting, or may be provided by having the tubular shaft G extended upward through the The shaft G depends from the vane-casting, passes through the cap B on the tower, and its lower end is carried to a suitable distance below ythe cap and is held by a spider, H, which is secured to the posts of the tower. The spider consists of a flat plate provided with ears or lugs adapted to receive the bolts by which it is secured to cross-bars I on the posts of the tower. It is provided with a central opening, through which the shaft G extends, as shown. By means of the spider thelower end of the shaft can be adjusted from side to side to bring the mill to a vertical position.

VOn the lower end of the shaft G a collar or cuff, J is fitted and rigidly fixed thereto bya set-screw. The cuff and spider prevent the mill from being raised upward. The lower end of the cuff is partially closed by an inwardlyextended rim, which serves as a support or bearing for a guide plate or disk, K,

which is provided with an `angular opening,

through which the angular pump-rod passes. The disk is also provided with a small opening to permit the passage of the governor wire or cord, hereinafter named. The disk has the same diameter as the inner diameter of the cuff J, and extends under the end of the main shaft G, as shown. When the wheel is turned in or out of the wind, the pumprod isv also turned, and the disk turns with the movement ofthe latter. The purpose of this disk is for centering the pumprod in the shaft, and

serves as a guide therefor.

The lower end `-of the bearing on the lower arm of the vane-casting rests on the cap B, and turns in a seat therein. The end of the bearing on the lower arm of the wheel-casting fits over and turns upon the upper extension, G', on the' vane-casting, and it rests on the upper end of the bearing C', as shown.

The bearing D2 on the upper arm of the wheel-casting extends over the top of the upper bearing on the vane-casting, and is provided 'with a depending tubular journal or spindle, on which the bearin g of the vane-casting is jonrnaled.` The journal L is extended below the bearing E, and acollar, M, slipped thereon and up against the lower end of said bearing, and is securely ixed in place by a set-screw. p

When it is desired to erect the'mill on thc derrick, thewane or rudder is bolted to the vane-casting, and the vane and its castings are placed in position and the wheel-casting,with its wheel,isr placed in its place by allowing the lower end of the wheel-casting to slip over the extension GYand the tubular journal on the wheel-casting to pass through the opening in the bearing E on the vane-casting, and they are held together by a collar on the, lower end of the tubular journal on the wheel-casting, and if necessaryjo separate the two castings, it is only necessary to remove the collar and pump-rod.

A tubular spindle, N, is provided on which the wheel is supported and revolves. This spindle is projected horizontally from and is held in place by the wheel-casting or frame D. The spindle is preferably set to one side of the center of the wheel-casting, so as to bring the axis of the wheel in a vertical plane different from the vertical plane in which the vane stands. When thus arranged, the wheel will be turned outof the wind when the latter is blowing with a velocity suflicient to overcome the weight ol the governor. yThe central bore or opening in the 'spindle permits the passage of the wheel-shaft O, which is lubricated from the oil-cup Q. The spindle N will be provided with suitable grooves in its outer side, andv with suitable openings made through it to let the oil which is fed from the cup Q pass to the shaft 0.

When the weather is cold and the wheel is j stopped, the oil within the grooves and openings in the spindle is liable tobecome chilled, and rthereby prevented from running into the reservoirs. fhen the wheel is started, the chilled oil is .at once sufficiently warmed by the action of the shaft 0, and is thinned and runs outward and inward as the wheel revolves, and therebylubricates both the spindle and the axle.

The hub P of the wheel P is provided with an axial bore through which the wheel-shaft O is passed. The hub and the shaft O are rigidly secured together by key, set screw, or other well-known means at or near the outer end of the said shaft. The hub is bored out or otherwise formed, so as to provide an enlarged axial opening, P, whereby there 'is formed a sleeve, P, which slips onto and supports the wheel on its stationary spindle N.

The enlarged axial opening. extends fromthe inner end ofthe hub to a point or vertical line approximately in the same vertical plane with the wheel. The weight of the wheel is supported by the spindle N. The inner end of the sleeve of the hub forms a close joint with the casting D, by which dust is excluded. The wheel-shaft is made fast in the outer end of the hub, as before mentioned, while its inner end passes through the hollow spindle, and is provided with a crank, R, or other suitable dvice, vwhereby it is connectedV with and imparts motion to the pump-rod S or other operating machinery. I

A series of oil-reservoirs, T, are arranged around the sleeve P3, so that they discharge their contents onto the spindle N. These reservoirs are sufficient in number and are so disposed aroundthe hub or sleeve that at least one of them will be on the under side thereof whenever the wheel is stopped. The oil in warm weather will drain into the pendent or under reservoir when the mill is at rest, and thus prevent the loss by the drainage at the ends of the bearings, as resultsl with ordinary constructions. The oil is retained in the pendent till the wheel is again set in motion, and the instant the full reservoir is raised *it discharges its contents onto the spindle. By this arrangement a great savingin oil is made and the bearings are lubricated just at the instant when most needed. The reservoirs are provided with removable caps, so that they can be opened when necessary for the purposes of cleaning lrhern or for relling. The arrangement ofthe oiling-cups and `construction of the sleeve and spindle, as hereinbefore explained, obviates the necessityfor the frequent oiling required by. ordinary mills, waste is .l

y with a head, S', at its lower end, through which the wrist-pin S2 passes into the crank R. The tubular part of the pitman terminates at the wrist-pin S, as shown. The upper end of the pitman is provided with a suitable head, S3, and so arranged as to leave the end of the said pitman open, and provided with an oi-linlet, so that the oil can be poured into it. The Wrist-pin S, by which the pump-rod is secured to the head S3, passes through the hollow pitman, as shown. The oil is permitted to pass downward, either through grooves made in the wrist-pin or through spaces formed by a slight enlargement of the pitman to permit the oil to pass around the said pin. Oil poured in the top of thc tubular pitrnan lubricates both wrist-pins.

rllhe pump-rod passes down throughsuitable guides, U, which are bolted upon the casting D, and upon the top of each one of these guides U is formed an oil-cnp, V, which is iilled with any suitable material, so as to pre vent the oil from leaking away too rapidly. Each of the guides U is grooved underneath, and in these grooves are placed the slotted adj ustable plates W, which are held in position by the same bolts which hold the guides in place. rlhese adjustable plates XV bear against opposite sides of the pump-rod, and serve to keep it always ina vertical position and to prevent any side movement, and can be adjusted to take up wear.

Secured upon the top ofthe Vvane-bar is a casting, X, upon the rear end of which is secured abolt or rod, which se'rves as a journal for the triangular-shaped lever Y. Clamped against the outer side of the lever Y, which is provided with a suitable seat for that purpose, is the rod Zupon which the sliding weight is placed, and which weight serves to pull the wheel back into the wind as soon as it is free to move. One ofthe ends of this triangular lever Y is connected directly with the casting D by means of the rod 1, while its other end is connected by means of the rod 2 with the lever 3, which is pivoted upon the front end of the casting X. The inner end of this lever 3 eX- tends nearly over the center of the mill and has connected to it the rod, cord, wire, or`

chain 4, by means of which the wheel can be turned around with its edge to the wind whenever it is desired to stop its movement. The casting Dl is provided with suitable projections, D, which prevent the wheel from moving too far in either direction, and these projections strike against rubber springs C3, in order to prevent any unnecessary jarring or shaking.

The spindle and hub, when constructed in the novel manner shown and secured together by the shaft, make a stronger and more durable wheel-connection than any of the ordinary known means.

rlhe shaft O is relieved from all strain caused hy the weight of thel wheel, and by reason of 'this a much smaller shaft can be employed,

and all jarring incident to ordinary wheels is avoided.

Having thus described my invention,whatl claim, and desire to secure by Letters Patent, 1s-
