IMPROVEMENT INWINDMILLS.

Specification forming part of Letters Patent No. 171,630, dated December 25, 1875; application filed March To all whom it may concern:

Be it known that I, ARTHUR T. PAGE, of Garden Prairie, in the county of Boone and State of Illinois, have invented a new and useful Improvementin Windmills and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 represents a perspective view of my improved windmill, and Fig-=2 represents a rear elevation of a portion of the same.

Similar letters of reference denote corre sponding parts'in both figures.

The invention relates to a novel arrangement of means for holding the Wheel in the face of the wind, and for deflecting the same therefrom, as the force of the Wind increases beyond what is required for rotating the wheel with the desired velocity, and to certain details of construction and arrangement of parts hereinafter fully set forth.

In the drawings, Arepresents the tower, which may be of any usual or preferred construction. The upper part of this tower is provided with suitable bearings for the reception and support of a hollow vertical cylinder, B, which forms the pivot on which the windmill, as a whole, turns to accommodate itself to the direction of the wind, and centrally through which the pump-rod 1) passes, said rod further passing through suitable guides, as at a. At difl'erent points in its length, near the upper end of this hollow pivot B, is secured a horizontal stud or studs, carrying a friction-roller, b, which rests on the top plate A, this roller, where but a single one'is used,

sleeve the collar B is provided with an angleiron socket, c, in which is secured the upright wooden block 0, to which, midway of its height, thevane D is rigidly secured, as shown.

cured, in any suitable manner, an angle-iron,

is provided with a sleeve, E,arran ged vertically over the pivot B, or nearly so. The sleeve E affords bearings for a vertical shaft or pivot, which is retained in position therein by an enlarged head or collar, F,'at its upper end. The lower end of this shaft has a yoke or arched plate, G, permanently secured to it midway of its length, and the depressed ends of this yoke or arch-plate are provided, each, with a sleevebearing, g, in which the wind-wheel shaft H is mounted, said shaft, between its bearings g, being provided with a crank at h, through which motion is imparted to the pump-rod. To the outer projecting end of the crankshaft H the wind-wheel I is rigidly connected, said wheel, by preference, being of that class known as the solid wheel, in which the blades are rig-- idly attached at the preferred angle ofobliqut' jty. The central radial arms or spider l are 1 dished on the inner face of the wheel, in such manner as to bring the weight of the wheel as nearly as practicable into the same vertical plane with the vertical pivots of the wheel, thereby reducing the tendency to .crampthe pivots in their bearings. The collar F on the upper vertical pivot ,is provided with a toothed beveled segment, f, and the sleeve E, in which said pivot or shaft has its bearings, has a horizontal stud-shaft, 0 projecting from it on one side, upon which is -mounted a sleeve, K, the inner end of which has cast upon it a perpendicular arm, is, with a cross-head, 7c, the inner face of which is pro vided with a beveled segme11t-rack,j", the teeth of which engage with the teeth of the segment f,'for vibrating the rack-pivot F. To the rear face of the sleeve K is secured a lever-arm, L, upon which is a sliding weight, L, by the adjustment of which the wheel, through its connection therewith by the pivot F, segment f and f, and sleeve K, may be held to the wind with any required power. To the upper end of the pivot F is permanently secured -a horizontal arm, M, extending rearward at right angles to the plane of the wind-wheel, or thereabout, and to the rear end of thisarm a transverse bar, M, .is secured, to which a number of slats, m, are connected,

To the upper end of .this block O is firmly se- E, the outer end of the horizontal arm e of which said slats being set obliquely to the planeof the wind-wheel, as shown, andserving, as the force of the wind is increased beyond what is requisite for giving the desired velocity to the wheel, to deflect the wheel or turn it onits pivot F slightly away from the wind, in which position the direct action of the wind upon the wheel itself will serve to further turn it out of the action of or away from the wind,

swinging it around on its pivot F toa position 1 more or less approaching aplane parallel with the "ane, according to the force of the wind. In this movement the segment f, acting on i the rack j, and thence through the sleeveK on the arm L, raises the weight L, which steadily resists the deflection of the wheel, andcauses it to return more or less directly into the face of the wind as the force of the latter abates.

Thus far it will be seen that the action of the wheel is automatic. For placing it under thecontrolof the attendant on the ground, a lever, P, is pivoted loosely on the outer end of the stud-axle 0 from the short arm 10 of l which a. cord, q, extends downward through thetubular shaft B, and is connected at its lower end with a lever, Q, near the ground, The long arm P of this lever is bent at 10 into an angular or cranlr form, reaching under the weighted arm L, which vibrates. on the same center e,as explained. This arm 1? has an adjustable weight secured to it sufficient to counterbalance the weight of the cord g and lever Q, and to remove it from contact with the arm L, as shown, so as to leave thelatter unobstructed in its automatic action, as explained, except when it is desired to turn the wheel away from the action of. the wind by hand, when the attendant, by pressing down on lever Q, raises: the long arm of lever P, i bringing it up into contact with the arm L,

when, by a continued movement of the lever P, thearm Iu will beraised, turning the-wheelsh'aft on its vertical pivotF, through the rackconnection described...

The lever Q may be locked inthis depressed position-for holding the wind-wheel wholly or 1 partially out of the. face of the windby a rack and pin, or any suitable device for the purpose.

Upon one of the sleeve-bearings g, or to any convenient point on the yoke G, is se-. j

cured a transverse stop-bar, R, the ends of which strike against the upright portion ot the supporting-iron E,-and limit the move i ment of the wheel relatively to the vane on the pivot F, within an arc of a circle of ninety degrees, or from a position in which thefacc 1 ofthe wheel is at right angles to the vane, to.

one in which it is parallel therewith, or nearly so, and vice versa.

cramp the latter in its bearings, and this is ina measure obviated by the arrangement of i the friction-roller b, as explained. For further overcoming this an arm, S, is projected from the collar B, and rigidly connected therewith on the side opposite to the standard 0 and to the vane, and'upon this isplaced a sliding weight, S, which may be set at, anydesired point, for balancing the weight of the vane and block,and standard 0.

Parts of the mill and of its supporting-tower not specifically described above may be of any usual construction.

The mill has been described with reference 1 to its. application for driving the pump-rod; but it will: be obvious that it may be used for any of the purposes to which this class of wind-wheels are applicable.
