WILLIAM IV. HILDRETH, OF DECATUR, INDIANA.
WINDMILL.
SPECIFICATION forming art of Letters Patent No. 392,981, dated May 15,1888.
Application filed December 10, 1887. Serial No. 257,516. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM W. HILDRETH, a citizen of the United States, residing at Decatur, in the county of Adams and State of In diana, have invented certain new and useful Improvementsin lVindmills; and I do declare the following to be a full, clear, and exact descrip: tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in windmills, and has special reference to the means employed to regulate and control their movements.
The invention consists in a vertical tubular shaft capable of a rotary horizontal movement in suitable bearings, avane and a wheel-bracket mounted on said shaft, the vane-bracket stati'onary on the tubular shaft and turning therewith and the wheel-bracket having a limited horizontal movement on said shaft, a vane pivoted to the vane-bracket, a shifting lever pivoted to the bracket for lifting the vane and for throwing the wheel out of the wind, and in the means employed for limiting the movement of the vane and the wheel and for operating the shifting lever, as will be hereinafter more fully set forth and described.
In the accompanying drawings, Figure l is a side elevation of my improved windmill, showing the wind-wheel in the wind. Fig. 2 is a similar view showing the wind-wheel thrown out of the wind. Fig. 3 is alongitudinal section of the bracket and the vane pivoted thereto, drawn on line :0 x of Fig. 1. Fig. 4 is alongitudinal section of the vane and wheel-brackets and connecting parts, drawn on line 3/ 3/ of Fig. 1. Fig. 5 is a plan view of the cap piece or box at the head of the vertical tubular shaft and a portion of the bracket-arm to which it is secured. Fig. 6 is a crosssection of the thimble at the base of the tubular shaft, showing the circular horizontal plate which fits loosely therein, and through which the pump-rod and lever-rope have a movement. Fig. 7 is a vertical sectional View of the parts referred to in Fig. 6, and a portion of the tubular shaft on which the thimble is secured. Fig. 8 is a vertical section of the boss on the vane-bracket which supports the vane, showing the rubber buffer held therein. Fig. 9 is a detached detail of the bo or cap piece through which the pumprod works and which acts as a rotary guide thereto.
In the drawings like figures and letters indicatelike parts.
A is the vertical tubular shaft upon which the vane and the whcel-brackets are mounted, and through which the pump-rod S has its movement. This shaft is held in position by the derrick-cap P and the spider T, through both of which it passes. The spider is secured between the derrick-posts by means of the radial arms or bolts 12.
R is a thimble secured to the tubular shaft immediately below the spider, and is secured to the shaft by the set-screw m. It is provided at its lower end with an inwardly-projecting flange, 6. The purpose of this flange is to re tain the circular horizontal plate 5 in its position at the end of the vertical tubular shaft, and to allow of its partial rotation at the base thereof. This circular plate is provided with openings, as shown in Fig. 6, through which the pumprod S and the lever rope or wire 3 pass.
It will be seen that the circular plate acts as a guide to the pump-rod and rotates with it horizontally when the rod turns in the shaft as the wheel is thrown in and out of the wind.
The cap piece or box a at the head of the tubular shaft through which the pump-rod moves is secured to the upper face of the bracket arm a by cap-screws, and is preferably formed in two parts, the cap-plate pro vided withan elongated slot through which the lever-rope passes into the tubular shaft, and a vertical flange, a, recessed on its side for the passage of the pump-rod, and a side plate, chbolted or screwed horizontally to said Vertical flange, forming,whcn in position, the box through which the pumprod has a move ment. (See Fig. 9.)
The vane-supporting bracket B is mounted on the shaft A through arms 8 aformed on the bracket. The bracket is prevented from turning on the shaft by means of the set-screw 25, passing through thelower arm, 15, so that when the vane turns by the action of the wind it carries with it the tubular shaft upon which it is mounted.
The vane H is secured between the extension-plate bars G G and pivoted to the bracket B at the inner end of the extension-bars, so as to admit of a vertical movement to the vane when lifted. The bracket has a boss, 11, at its lower rear end, said boss being preferably hollow, so as toretain a rubber buffer or a coiled spring in position, as shown in Fig. 8, wherein p is the buffer and p the bolt that holds it in place. The object of the boss is to support the vane in its normal position, the projecting rubber being provided to prevent undue shock when the vane is lowered upon the boss.
K is the shifting lever, through which the vane is lifted and the wind-wheel thrown out of wind. It is formed in one piece, slightly hipped at the fulcrum-point, so as to carry its lower end clear of the side plate to which the vane is secured,and is pivoted at 17 on the upper rear end of the vane-bracket,and has a projecting arm or lug, K, which acts as a bellcrank lever when the upper arm of the lever K is thrown forward for the purpose of lifting the vane H and throwing the wheel bracket and the wind-wheel thereon at rightangles to said vane. The projecting arm K of the lever is connected to the vane by thegraduating-plate L and the link L. The graduatingplate is provided with a series of eyes similar to those in the projecting arm of the lever, so that the link may be shifted and the elevation of the vane regulated thereby. The plate is secured to the vane by bolts or otherwise. The lower end of the shifting lever extends below the pivotal point and is connected by rod K to arm 0', which is formed on the bracket 0 and projects at right angles therefrom. (See Fig. 4.) The object of this connection is to cause the wheel-bracket to be drawn around when the lever is drawn forward and the vane lifted. The release of the lever causes the wind-wheel to be thrown into the wind by the falling of the vane into its normal position,as shown in Fig. 1.
M is a vertical arm, carrying in its upper end a pulley-sheave at 4. This arm is secured to the vane-bracket, the sheave supporting the rope or wire that leads from the lever K down through the tubular shaft to the ground.
The wheel-bracket G is mounted on the tubular shaft through arms a a, and has a limited horizontal movement on the tubular shaft. The lower arm, t, of the vane-bracket supports the lower arm of the wheel-bracket, while the lug g on the vanebracket overlaps the arm a, and thereby prevents the vertical displacement of the wheel-bracket on the tubular shaft.
The wind-wheel D is mounted on the driving-shaft E, said shaft being j ournaled on the bracket G, the box-cap It being secured in position by screws or bolts. (See Fig. 1.)
N is a crank-wheel, carried on the inner end of the driving-shaft, and actuates the pumprod S through the pitman O. The wheelbracket is provided with horizontal lugs, forming stops 8 9, these stops being formed at right angles to each other and intended to limit the horizontal movement of the wheel-bracket on the tubular shaft when the wind wheel is thrownin and out of the wind.
The wheel D is provided with radial arms D and brake-ring D", the latter secured to the rear face of the arms and acting as an annular brace thereto. The slats or inclined blades of the wheel are secured to the radial arms by screws or bolts, and are strengthened in their position by brace-rods extending from said slats to the swivel-cap e on the end of the forward extension of the drivingshaft E.
. The brake F (shown in Figs. 1, 2, and 4) is pivoted to a lug, '0, at 'w on the wheel-bracket 0. It is connected by wire ropef to an eyebolt, n, on the vane-bracket. When the wheel is thrown out of wind, the wire which connects the brakelever with the bracket is drawn against the vertical tubular shaft. This increases the tension of the wire which operates the brake-lever and forces the brake-head against the brake-ring D". In order to prevent the possible shock which might follow the too sudden stoppage of the wind-wheel, a spring or rubber buffer may be secured to the brake-head similar to that provided on the boss 19 of the bracket B. The recoil action of the springbuffer when the brake is released will cause it to clear the brake-ring when the wheel is thrown into the wind, or the brake may be applied against the action of a spring secured to the wheel-bracket, the result being the same by either method.
The derrick-cap P, hitherto referred to, through which the vertical tubular shaft passes, is provided with a flanged neck, Z, and
is constructed with flanged side pieces, Z, the
object being to prevent the entrance of water, thus saving the derrick-posts from decay.
The operation of my improved windmill is as follows: When all the parts are in position, the lower arm of the vane-bracket rests upon the neck of the derrick-cap, and with the tubular shaft, to which the bracket is attached, has a horizontal movement thereon. As the thimble R at the base of the shaft abuts against the under side of the spider-frame T, it will be seen that any tendency to lift on the part of the mill is effectually prevented. The turning of the wind-wheel actuates the pump-rod through driving-shaft E, crank-wheel N, and pitman 0. When it is desired to throw the wind-wheel out of wind, the shifting-lever is drawn forward by the wire rope 3, thereby lifting the vane, and at the same time, through the connecting-rod K throwing the wheelbracket and wind-wheel mounted thereon out of the wind. In order to facilitate this movement, the wheel-bracket is mounted on the tubular shaft slightly to one side of its center or to the turning side of a line parallel with the vane-bracket. By releasing the lever from its forward position the weight of the vane, as
