GEORGE M. BEARD, OF ANGOLA, INDIANA.

SPECIFICATION forming part of Letters Patent No. 258,352, dated May 23, 1882.

Application filed January 27, 1882. (No modohi v To all whom it may concern Be it known that I, GEO. M. BEARD, of Angola, in the county of Steuben and State 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 descriptionof the invention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in windmills; and it consists, first, in the frame in which the wheel-shaft isjournaled, and which is curved laterally, so as to throw the wheelshaft out of line with the vane, and thus enable the wheel to swing around out of the wind; second, in the arrangement and combination of parts which will be more fully described hereinafter.

e The object of my invention is to produce a cheap, simple, and reliable windmill in which the wheel can turn upon suitable pivots so as to be brought in a line with the vane, and thus be made to regulate itself in storms.

Figure 1 is a side-elevation of my invention, partly in section. Fig. 2 shows detail views of the guide-support. Fig. 3 is a detail section view of the operating parts. Fig. {L is adetail view.

A represents the derrick, B, the wheel; G, the vane, and D the turn-table. This table is made in the form of a tube, which extends downward a suitable distance below the top of the derrick, and upon thetop of which is swiveled the casting E, upon which the wheel is journaled, and the casting F, to which the vane is secured. This casting F is provided with two stops, G, which are placed at nearly right angles to each other, and which serve to regulate the distance which the wheel shall turn by having the lug H strike against them. Upon each side ofthe lug which strikes against the stops is secured a suitable block of rubber, I, which is held in position in any suitable manner, and which prevents any jar or concussion to the wheel as it is moving in and out of the wind.

The casting E, upon which the wheel is journaled in the usual manner, extends upward a suitable distance beyond the wheel-shaft, where line with the vane, whilethe pump-rod N passes down through the center of the turn-table. The connectingrod L passes up through the opening 5 in the guide 1, and is connected to the pump'rod above the guides 6, by which the pumprod is held in a vertical position. As the crank-wheel revolves it makes a quick downward stroke from the point 7 to the point 8, being assisted by the weight of the pitmanrod N, and then makes aslow upward movement whereit has water to lift in the pump or other work to perform. This construction prevents that sudden jerk orjar upon the pumprod which always ensues where the parts are placed in line, and which, where the movement of the crank is about the same all the way around, has a tendency to shake and loosen the different parts of the mill.

After the lower end of the pitmau has reached its lowest point it is nearly in a line with the pump-rod, and as the crank forces the pitman L upward it moves the pump-rod upward in almost a vertical line, and thus there is but little friction upon its bearings. Where the pitman does not rise in a line with the pump-rod it forces its upper end sidewise, and thus creates aside pressure upon the pump rod which adds very materially to the work of the wheel. On the inner side of this wheelcasting is secured a suitable guide-support, 1, up through which the pitman-rod L passes, and to the upper end of this pitman-rod is bolted the pump-rod N. The guide-support 1 is bolted securely to the inner side of the casting E, and has the large opening 5 through its inner end, up through which the pitman L plays back and forth. Through the extreme inner edge of this guide-support is formed the recess 9, up through which the upper end of the pump-rod passes. This pump-rod is secured in position by the two slotted and adjustable guides 6, which rest upon the top of the support, and which are grooved in the under sides of their inner ends, as shown, so as to catch over the flange which is formed upon the part 12 of the support, and thus prevent the guides from twisting or getting out ofplace. Each one of these guides is provided with two grooves, 13, so that they can be made reversible and used upon either side, as may be desired. By making these guides adjustable they can be adjusted in such relation to each other that the upper end of the pump-rod will have no lateral play whatever, or they can be moved outward so as to let the pump-rod have any desired amount of lateral movement.

Upon the inner end of the guide for the pitman-rod is formed a suitable guide for the pump-rod, and in the lower end of the turntable is formed another guide, so as to keep the rod in a vertical position. A third guide may also be formed by putting a cap or plate, O,-upon the top of the turntable which will have-a small opening throughit, and which plate will also serve to keep snow, ice, and rain from gettinginto the interior of the turntable. This cap 0 has an extension, S, formed uponvone side, which acts as a lever when the wheel-casting E is being turned around, so as go-draw down through a suitable connectingrod upon the short end of the lever It. This cap, being bolted rigidly to the casting E, of course moves with the wheel, and when the wheel is moving around toward the vane the extension S exerts a pull upon the lever B, so

as to raise the weighted end of the lever upward. As soon as the wheel is left free to move the weighted lever causes the casting E to revolve upon the top of the turn-table D, and thus bring the wheel into the wind again.

The spider X, to which thearms ot'the wheel areattached,insteadot' being madein the usual form, is here made cup-shaped,so as to extend backward over the top of the wheel-shaft a sufficient distance to bring the arms or weight of the wheel over,or almost over, the center of the shaft. Where the spider is made straight in the usual manner, the whole weight of the wheel is made to bear upon the outer end of the shaft, and the consequenceis that the shaft bears unevenly upon itsjournal, and soon becomes more or less injured and the wheel out of line, so'as to cause the entire mil-l to tip to one side. Where the whole weightofthe wheel ,is equally divided upon the bearing the shaft will wear evenly at both ends and the wheel always retain a vertical position. This construction of the spider is agreat improvement in windmills, for it will cause the parts to work evenly and true for a muchlonger time. Fastened to this lower weighted end at any suitable point is the rope, cord, or wire which passes up overthe pulley S, which isjourualed in the top part of the vane-casting, as shown.

In the lower end of the turn-table is placeda grooved ring, T, which is made in two parts, so that the lower guide for the pump-rod can be placed between the two parts, and then the two parts pushed up into the lower end of the turn-table D, where they are secured in place by means of a set screw, 2, which passes through a collar, 3, and the lower end of the turn-table. This collaris placed upon thelower end of the turn-table, so as to prevent themill from being raised up out of position in any manner.

The vane is braced rigidly in positionby means of a rod, 4, which is fastened to the upper part ofthe vane-casting, and which extends backward, as shown, and is then fastened to the vane O at any suitable point.

Having thus described my invention, I-

claim- .1. The combination of the turn-tablewith agrooved ring madein two parts, the guide for the pump-rod, which is placed inside'of the divided ring, and a set-screw for holding the parts in place, substantially as set forth.

2. In a vertical wind-wheel, the casting E, in which the wheel is journaled, and which is curved laterally, so as to throw the wheelshaft out of line with the vane, and thus enable it to;swing around out of the wind, substantially as shown.

3. The combination of the guide-support 1, having an opening for the pitman to pass through, with the guides 6, which are placed upon its top and made adjustable, substantially as described.

4. The combination of the guide-support 1, having a flange formed upon the part 12, with the guides 6, having the grooves 13 formed in their under sides, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
