WINDMILL.

SPECIFICATION forming part of Letters Patent No. 351,587 dated. Qetober 26, 1886.

Application filed April 15, 1886.

To all whont it rncty concern: 7

Be it known that I, FRANKLIN FANNING, a citizen of the United States, residing at St.

Joseph, in the county. of Buchanan and State of Missouri, have invented certain new and useful Improvements in Windmills, of which the following is a specification, reference being had therein to the accompanying drawmgs. I

This invention relates to certain improvements in Windmills, being principally designed for pumping purposes, although it may be employed for all purposes where a vertical reciprocating motion is required.

The invention is designed to provide improved mechanism for imparting th e necessary vertical reciprocating motion to the pump or other rod, and also provide means whereby the wheel may be thrown perfectly parallel with the direction of the wind, so as to be entirely out of its force, as more fully hereinafter specified.

The above-mentioned objects I attain by the means illustrated in the accompanying drawings, in which Figure 1 represents a View, partly in side elevation and partly in elevation, of my improved windmill; Fig. 2, a top or plan View of a portion of the same 5 Fig. 3, a partial front view of the wind-wheel; Fig. 4, a detached view of the mechanism for operating the vertical reciprocating rod, and Fig. 5 a detached sectional view of the rim of the wheel and one of the vanes in elevation.

The letter A indicates a vertical hollow' shaft, which is suitably swiveled in hearings in the tower, as usual.

B indicates a frame mounted onthe upper end of said shaft, and braced loy-means of the oblique beams C. To the forward end of the frame B is pivoted a cast-iron frame, D, having bearings E for the shaft F of the windwheel G, which is supported upon its outer end.

The letterH indicates a segment pivoted to a lateral arm, 1, extending from the frame B. The said segment is provided with an arm, K, which connects by means of a short link, L, with the frame D, for the purpose more fully hereinafter described. MI indicates a curved Serial No. 198.915. (No m0del.l

guide, through which the arm K works, and which limits its movement. The segment is provided with two grooves, and with ropes or chains N P, extending in opposite directions downward over pulleys It S, the chain 1? being connected with a weighted lever, T, and the chain N with mechanism below for turning the wheel to and from the wind, as usual.

The lower portion of the frame D is provided with ways or guides U, and the upper part with a guide-opening, V, in which is adapted to slide a reciprocating bar, W. The said bar has pivoted to it one end of a camrod, X, which has at its other end a cam-strap, Y, in which works a cam, Z, secured to the wind-wheel shaft, whereby the sliding bar is operated. v The said bar is provided with lugs A, which embrace the walking-beam B at one side, the saidbeam being fulcrumed between pillow-blocks O,secured to the beam D. The end of the walking-loeam is bifurcated and has internal lugs,E,which set between the heads of the drum F, mounted upon a vertical rod, F, secured to brackets on the frame D, as indicated in Fig. 4 of the drawings. The walking-beam is provided with aseries of fulcrum-apertures, l)", by means of which it may be adjusted to vary the stroke of the pumprod, as maybe required. The other end of the walking-beam is bifurcated and provided with lugs similar to those first mentioned, which connect with a drum on the pumprod, so as to operate the same.

The wheel is composed of a radial spider, E, having a suitable hub, F, and a series of radial arms, G. To' these arms are secured the concentric rings H 1, between which the vanes are supported. These vanes overset the rings at each end, the said ends being slotted for the purpose in such manner that they will be presented to the windat an angle thereto. The outer rim is re-enforced with a ring, K, and the whole is bound together by an annular external band of iron, L.

The operation of my inventionis as follows \Vhen in operation the rotation of the windwhcel and its shaft transmits a reciprocating motion through the medium of the cam and cam-rod to the slide operating the walkingbeam, oscillating the same. This'givcs the desired movement to the vertical reciprocating rod.

When it is desired to throw the wheel out of the wind or parallel with the line of its direction, the cord or chain N is drawn upon, moving the segment H. and arm K, and by means of the link L moving the frame D on its pivot F until the wheel assumes the proper position.

Having thus described myinvention, whatI claim, and desire to secure by Letters Patent, 1s-

l. The combination, with the supportingframe mounted on the upper end of the hollow vertical shaft, of the frame pivoted thereto, the wind-whee1 and its shaft jonrnaled in bearings in said frame, the eccentric or cam and WALTER K. HARRINGTON, D. M. STUART.
