'WINDMILL.

SPECIFICATION forming part of Letters Patent No. 351,537, dated October26, 1886.

Application filed March 26, 1886.

. To all whom, it may concern.-

t be expanded to throw the floats into the wind,

or such arms may be thrown back in a line substantially parallel with the crank shaft, thereby throwing the floats backward and causing them to present their edges to the wind.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a rear view of the windmill, one of the floats and its supporting-arm being removed to disclose the construction of the main supporting-pivot. Fig. 2 is a side view of the mill, the pivot and its supporting-plate being shown in central vertical section, and the hub carrying the float-arms being also shown in central vertical section.

The windmill forming the subject-matter of this application could be mounted on any form of tower or mast desired; but it is preferably mounted on a mast made of cast or wrought pipe set in a vertical position and properly guyed, as indicated in Fig. 1, wherein A represents the mast. .To the upper end of the'mast Athere is secured a plate, B, formed with a central aperture and with a downwardly-extending plate, b, at the bottom of which there are arranged outwardly-projecting horizontal arms a a. The main pivot O of the mill is fitted within the aperture formed in the plate B, and guided at its lowerv end by the arms a a, being held in position by a strap, a, that is held to the arms aa by set-screws, the lower end of the pivot 0 being formed with an annular groove, (1, in which the arms a a and the strap c'are fitted. The pivot G carries a plate, D, that is provided with vertical standin these standards there are I allowed to drop to the position shownin dotted ards e e, and

Serial No. 196,660. (No model.)

formed bearings which support and hold the crank-shaft E. Upon the extending end of the crank-shaft E there is a hub, F, formed with radial arms f, as many of such arms being provided as there are to be floats in the mill. The floats G G are rigidly secured to their supporting-arms H in any manner desired, but preferably by means of loops andsetscrews, as indicated in the drawings. The arms H are each provided with auxiliary or bracing arms h, and the inner ends of the main arms H and of the auxiliary arms h are apertured, so that they may be fitted upon the armsf ol" the hub F, being held to place upon said arms by pins 13, or by nuts or any other convenient device which will prevent the displacement of the arms.

A sliding collar, I, is mounted on the shaft E,

between the hub F and the outer standard, 6, and this collar 1 is provided with as many pinsj as there are armsf on the hub F, and each of these pins j is connected with one of the arms H by a connecting-linlgas Z, said links being pivotally connected to the arms H, and loosely mounted on the pins j. To the side of the plate D opposite to that from which the shaft E projects there is secured a bracket, K, and to this bracket K there'is pivotally connected a lever, N, to the end of which there is secured a weight, N. This lever N is connected to the collar I bymeans of a bifurcated connectinglink, L, the forked end of which straddles the collar, so thatthe pins or pr0- jections 0, carriedby said forked end, may enter a groove formed in the collar. The short arm of the lever N is formed with an Lshaped projection, n, and to this L-shaped projection -12 there is secured a wire, 19, the lower end of which-is fixed to a yoke, q, encirclinga collar, P, within which the main connecting-rod R slides. This collar P is engaged by a forked projection, 1', which extends from a sliding plate, T, that is secured to the mast, and this plate T is in turn provided with a downwardlyextending wire, t, which is secured to a cleat near the ground. The crank-shaft E is connected to the rod R by means of the pitman or connecting-rod S, and a swivel-joint, V, is arranged in the shaft R, as indicated.

When it is desired to throw the mill into operation, the wire t is released and the lever N- lines in Fig. 2, and this movement of the lever will carry the float-arms forward, so that they will extend at about right angles from the axis of the crank-shaft, thus bringing the floats into a position to be operated upon by the wind, it being of course understood that the floats are set at an angle to the crankshaft.

When it is desired to throw the mill out of use, the lever N is drawn to the position shown in full lines in Fig. 2, which movement of the lever will throw the collar-I up close to the hub F and cause the arms H to swing upon their connection with the arms f until they extend to the rear of the shaft E in lines that are about parallel with the axis of said shalt.

The many advantages of such a mill as I have described are so perfectly apparent that it is needless for me to go into any extended enumeration of such advantages.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a windmill, the combination, with a crank-shaft, of a hub carrying radial arms, floats rigidly secured to arms that are pivotally connected to said radial arms, a sliding collar carrying pins, connecting-links extending from said pins to the float-arms, a lever,

and a link extending from said lever to the pin-carrying sliding collar, substantially as 30 described.

2. The combination, with a crank-shaft, of a hub carrying radial arms, floats that are rigidly secured to arms that are pivotally connected to the said radial arms, a sliding 001- 5 lar mounted onthe crank-shaft and carrying pins, connecting-links Z, extending from said pins to the float-arms, a weighted lever, N, a link, L, connecting the lever and the sliding collar,and an operating mechanism consisting. o essentially, of a wire extending to the ground and having an interposed swivel-connection.

3. The combination, with the turn-table ofa windmill and a shaft mounted thereon, of a hub mounted rigidly on the shaft and pro- 5 vided with radial arms, float-arms pivotally mounted on said radial arms, a sliding collar on said shaft, connections between said collar and the float-arms, and a weighted lever mounted on said turn-table and having its shorter 0 end connected with the sliding collar, substantially as shown and described.
