SPECIFICATION forming part of Letters Patent No. 425,841, dated April 15, 1890.

Application tiled August 31, 1889. Serial No. 322,568. (No model.)

To all whoml it may concern.-

Be it known that we, ELAM B. VINGER and OSWALD EVINGER, residents of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements inWindmills andwe do hereby Y declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates to improvements in windmills of that class in which both vane and wind-wheel support are pivoted to a central standard, the normal position of the windwheel being approximately at right angles to the line of the vane, and the parts being so arranged and connected that the swinging of the wind-wheel out of its normal position raises the vane.

The invention is fully described, explained, and claimed in this specification, and shown in the accompanying drawings, in which- Figure l is a perspective view of our improved windmill. Fig. 2 is a top plan of the working parts thereof. Fig. 3 is a similar view of those partsA of the mill lying below a horizontal plane passed through the line X X, Fig. 1. Fig. i is a vertical section through the line Y Y, Fig. 2; and Fig. 5 is a vertical section through the line Z Z, Fig. 3.

In these views, A is a windmill-tower of ordinary construction.

B is the top plate of the tower, and C is a Vertical standard journaled near its middle in the top plate B and at its foot in a sup' port h, secured to the timbers of the tower, Fig. l.

On the standard C, immediately above the top plate, is loosely mounted a revoluble ring D, provided with horizontal gudgeons cl, and on these gudgeons are pivoted the front ends of two castings d', whose rear ends clasp and are fastened to the mid-rib E of a vane of ordinary construction, the vane being thus connected with the standard by a universal joint allowing it to swing either vertically or hori zontally. Immediately above the ringD is a second ring F, rigidly secured to the standard by means of a key orzset-screwand provided with two integrally-formed extensions G G', approximately at right angles to each other,

the extension G supporting a horizontal box or journal inclosing an ordinary wind-wheel shaft g, on which is rigidly mounted a windwheel spider g', and the extension G being provided at its outer end with a pulley-block g, whose use is hereinafter set forth. The wind-wheel shaft G and vane E are approximately parallel to each other, but are not in the same plane, the wind-wheel shaftbein g set at one side of the vertical plane of the vane, in order that the wind may more readily swing it from its normal position toward the vane, and the rings I) F are formed with stops d f, adapted to limit the relative rotation of the two'parts. Both these features of construction are well known in mills of this class and are only mentioned descriptively.

On the top of the standard C is rigidly mounted a ring or cap I-I, provided with an arm H', lying in a vertical plane slightly oblique with reference to the plane of the wind-wheel shaft, and a wire W is fastened to the free end of the arm H and connects it with a point on the mid-rib E of the vane at a considerable distance from the standard O, thus supporting the weight of the vane.

brace h, fastened at one end to the extension G and at the other end to a suitable projection on the cap H, braces the frame of the mill and counterbalances the weight of the vane with that of the wind-wheel and the parts which support it. A chain I is fastened to the mid-rib of the vane at a point about as far from the standard C as the pulley g, already referred to, and is carried from the vane about said pulley g and over a pulley h', mounted on the cap H, and passes thence downward through the Istandard to the foot of the tower, the office of this chain being to draw the wind-wheel out of the wind by swinging the extension G and the wind-wheelsupporting parts in the direction indicated by the arrow in Figs. 2 and 3. The end of the wire WV may be secured to the free end of the arm H' in any desired manner; but we prefer to fasten it adj ustably in the manner illustrated in Figs. 2 andl, in which 71, is a transversely slotted extension of the arm, and Il is a block resting on said extension and provided with an annular flange h", and with a neck extending downward into the slot in said extension. A loop in the end of the wire Wncircles the block and rests upon. the iiange h'", and a cap h"", resting upon the block and projecting over the wire, is se cured by means of a bolt passing through the block and cap, and having at its lower end a head of a diameter greater than the width of the slot in the extension 7L". The block may be secured at any desired point in the slotted extension, thus varying slightly the angle of the wire W to the vane. It is evident that when the mill is in operation and the vane is held in any given plane by the force of the wind the swinging of the wi11d.-wheel.and its supporting parts i-n the direction indicated by the arrow in Figs. 2 and 3 will swing the arm H' in the same direction, and thereby raise the free end of the vane, and any variation of the angle of the wire to the vane will change the initial effect upon the vane of such swinging of the arm H'. It is also evident that the return of the wind-wheel to its normal position, after having been moved therefrom in the manner described, will also return the arm H' to the position shown in the drawings, and will there` by `permit the free end of the vane to drop down to its normal position, the weight of the vane being thus the regulating force which tends to hold the wheel in its normal position and to return it thereto after it has been moved out of such position.

On the inner end of the wind-wheel shaft g is rigidly mounted a crank K, provided with a crank-pin k, and on this crank-pin is pivoted the lower end of the pitman P, whose upper end is pivoted on a gudgeon 7c', projecting from a vertically-reciprocating slide S, conforming to the outer surface of the r vertical movement of the two slides S S'.

standard C. Theinner face of the upper end of the pitman rests against a boss or shoulder s, formed upon the slide at the base of the gudgeon 7c', and the inner face of the pitman at about its middle point rests against a guide s', also formed on the slide and lying in the vertical plane of the shoulder s. The upper end of the pitman is secured against accidental displacement in the manner hereinafter described, and the shoulder s and guide s' hold the lower end of the pitman in contact or very nearly in contact with the face of the crank K, and thereby dispense with the necessity of securing the lower end of the pitman in place by any means other than the plain cylindrical crank-pin 7c passing through it.

lVithin the standard C is a second slide S', conforming to the inner surface of the standardV and provided with vertical Webs T, extending through and sliding in aslot c in the standardand resting against the inner 'face of the outer slide S, and lugs t, formed on the webs T, extend into corresponding sockets in the slide S and prevent independent A half-round 4or half-oval pump-rod R rests against the inner concave face of the slide S', and suitable bolts pass through the two slides and the pump-rod and bind them firmly together, the bolts being so placed as to lie within the slot c of the standard C. One of these bolts passes axially through the gudgeon 7a' an d holds in place a cap 7c", of greater edges of the cap extending over a portion of the pitman P and preventing accidental disengagement of the pitman from the gudgeon.

We are aware that many of the features of the mill illustrated and hereinbefore described are old and in common use in the art, and such features are shown and described merely as parts of the operative mechanism including our invention. We therefore disclaim any novelty except such as is set forth in and covered by the following claims, to wit:
