WINDMILL..

SPECIFICATION forming part of Letters Patent No. 342,736, dated May 25, 1886.

Application filed March 8, i886. Serial No. 194,434.

.To @ZZ whom it may concern.-

Beit known that I, JOHN \V. OURRIE, of Solomon City, in the county of Dickinson and State of Kansas, have invented a new and Improved Windmill, of which the following is a full, clear, and exact description.

My invention relates to windmills, and has for its object to provide an inexpensive, strong, and durable mill, which may readily lo be thrown into and out of gear, and is selfregulating when in gear.

The invention consists in certain novelv features of construction and combinations of parts of the windmill, all as hereinafter fully r 5 described and claimed.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters indicate correspond- 1 ing parts in all the figures. 2'0 Figure lis a vertical sectional side elevation of the head portion of a windmill made in accordance with my invention, the windw-heel sails being removed and parts being broken away. Fig. 2 is a plan View, partly sectional, and shows in full lines the relative positions of the wind-wheel shaft and vane when the mill is in gear; and shows in dotted lines the position of the wind-wheel when the mill is out of gear, and Fig. o is a vertical 3o sectional elevation taken at right angles tov the same parts shown in Fig. l.

The head of the mill consists, mainly, of a four-way wrought-iron pipe-coupling, A, commonly known as a cross, opposite wrought- 3 5 iron tubes B C,threaded into the screw-necks l 2 of coupling A, and a third wrought-iron tube, D, threaded into the screwneck 3 of the coupling and extending at right angles to the tubes B C. The tube C is journaled in the 4o head-piece e of the mill-towerE,and is stepped in a bearing, e', on the tower. The armv F of the vane is swiveled by its eye f on the t'ube- O, between the neck 2 of coupling A and the tower.

The wind-vane is not shown in the drawings, but it may have any approved construction and be attached to the arm F in any approved way.

In a plug, d, fitted into the outer end of the 5o tube D, and in a plug, d', tted into the opposite neck, 4, of the cross-coupling A, there (No model.)

is journaled the wind-wheel shaft G, to which is Iixed the hub or spider II of the wind-wheel, and at the opposite end of the shaft is xed a crank-arm, I, to which is connected one end of a pitman, J, the other end of which is attached to a crosshead,K,which is fitted to slide in a slotted standard or guide, L, fixed-in any approved way to the top ofthe tube B, and to said cross-head K is attached the upper end of 6o the pump-rod M, which passes through the tubes B C, and is slotted or divided into two parts or limbs, m m,which pass, respectively,

at opposite sides of the windmill-shaft and thence downward to connect with the pump or other machine or gearing to be driven by. the mill. A brace-rod, N, connected at one end to the vane-arm F, is pivoted or hung at its upper end on a pin, n, fixed to the crosshead standard L,and supports the vane there- 7o from while allowing it to swing around freely with the wind.

To the vane-arm F there are xed a couple of straps, O O, which have slots forming guides, in which a bar, I), is fitted to slidefat the side of the vane-arm, aand about at the center of the bar P there is pivoted at r one end of a rod, R, the other end of which is pivoted at r to an arm, s, which projects from a collar, S, attached to the mill-head, which 8o supports the wind-wheel, and it may be by screwing it onto the exterior threads of the tube D before the tube is screwed into the cross-coupling A. A chain, T, is attached at t to the end of the bar P, and thence runs under a guide sheave or pulley, U, journaled on the vane-arrn F, and thence passes upward to and over a guide sheave or pulley, V, journaled at the top of the cross-head guide L, and thence passes downward through the 9o tubes and couplings B A C, as in Fig. l. A spiral spring, W, is attached to the lower end of the chain T, and to this spring is connected a wire or rod, X, which extends down to or near the floor of the mill-tower within reach of an attendant. f

The operation is as follows: When the attendant draws the rod X downward, the chain e T will draw the bar I endwise toward the mill-head, and thereby carry the rod R outroo ward and swing the mill-head around with the wind-wheel shaft G about in line with the vane on the arm F, and thus throw the mill into gear, and the rod X will be fastened in any way by the attendant. The rod R acts as a brace or stay to prevent the wind-wheel from swinging too far around by contact of the end of rod R next its pivot r with the inner collar O, and as will be understood from Figs. 2 and 3 of the drawings. Should the wind blow too hard or in sudden gusts, the wheel will be blown around more or less in the direction ofthe arrow l in Fig. 2, thereby forcing the rod R and bar Poutward or backward and pulling on the chain T and expanding the spring W incre or less, and the tension of the spring will cushion the resistance of the windl wheel and regulate its speed by holding more or less of the area of the wind-wheel sails to the Wind, the spring also preventing jar and shock of the parts of the mill. As the wind force decreases the wheel will gradually swing back again full face to the wind, as when first started.

To throw thc mill ont of gear, it only is necessary to unfasten the rod X and the wind will swing'the wheel around parallel with the vane as the rod R and bar P are moved back ward, and, asindicated in dottedlines in Fig. 2, the end of rod R next the pivot r then striking the outer collar O on the vane arm to prevent the wind-wheel from swinging against thevane. It is evident that when the mill is out of gear no strain is brought on the speed-regulating spring W, which then hangs loosely with the chain Tand rod X consequently the elasticity of the spring will not be impaired during such time.

The mill-head, made of wrought-iron crosscoupling A and tubes B OD, is less expensive to make and very much stronger than many styles of castiron heads, and with it a long wind-wheel shaft may be used, thereby facilitating the easy, steady working of the mill and promoting its durability.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent` is 1. In a windmill, the 1nill-head made of a .wrought-metal tubular cross-coupling and tubes fitted therein,and adapted to receive the wind-wheel shaft and give passage for the pump-rod and gear pull chain or cord, slibstantially as shown and described.

2. In a windmill, the niillhead made ofa wrought-metal tubular coupling, A, wroughtmetal tubes B CD, fitted therein, plugs dd', fitted, respectively, in the tube D and in the opposite neck 4 of the coupling A, the windwheel shaft G, journaled in said plugs d d', and said tube C, journaled and stepped in the niill tower, substantially as herein shown and described.

' 3. In a windmill, the combination of a head consisting of a tubular crosscoupling,A, tubes B C D, fitted therein, plugs d d', fitted, repectively, in the tubes D and in the opposite neck 4 of coupling A, the wind-wheel shaft G, journaled in plugs d d, and said tube C, journaled and stepped in the mill-tower, a crank, I, on shaft G, a connectingrod, J, a cross-head, K, connected to rod J, a guide, L on tube B for cross-head K, and a rod, M, connected to the cross-head and extending downward through the tubes and coupling B A C, substantially as set forth.
