IMPROVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 97,136, dated November 23, 1869; reissue X0. 5,354, dated l April 15, 1873;. application filed January 16, 1873.

To all whom it may concern: in which the bearing of the shaft rests. On Be it known that I, WILLIAM I. TUsTIN, of this spindle is placed loosely a pulley, G, havhe city and county of San Francisco, State ing a small pinion, g, secured to its upper face of California, have invented an Improved around the spindle. A connectingrod, I, ex-

Windm'ill; and I do hereby declare the foltends paralIel'w-ith the shaft 0, having at its lowing description and accompanying drawlower end a gear-wheel, Q, and on its upper ing are sufficient to enable any person skilled end a pinion, The upper end of this rod .in the art or science to which it most nearly passes through the rudderbar, and the pinappertains to make and use my said invention ion z engages with a segmental rack, a, while or improvement without further invention or the wheel on the lower end engages with experiment. the toothed pinion g on the pulley G, so that My invention relates to an improved conby turning the pulley the table F is turned struction of windmills, such as are employed around so as to stand at any required angle for obtaining power from the impulse of the to the rudder. Directly under the pulley G wind; and it consists in constructing the wheel is a clutchring, K, which is secured to the spindle so as to be stationary, and upon which the pulley G rests when not elevated by the lever L. Above the coupling, and on the under side of the pulley G, are projecting lugs 01' pins 24, which, when the pulley drops by its own weight upon the coupling, engage with it and prevent the pulley from turning, there by securing the wind-wheel in its required position relative to the line of the wind at all times, even shouldthe wind veer the rudder to a different position. An endless cord, 21, passes around the pulley G and over the small pulleys N on the cross-barB, and thence passing downward it passes around the pulley 0,- to which is attached a weight, P. A cord, 7', isattached to one end of a curved lever, L, which is secured upon one of the cross-timbers B directly under the pulley G, so that by pulling downward upon the cord the opposite end of the curved lever is elevated, carrying with it the pulley G, and clearing it from the clutch-couplin g so as toallow it to turn as may be required.

After the pulley has been freed from the coupling K, by drawing downward upon one side of the endless cord '0 the pulley is turned,causing the pinion i to operate thegearwheel Q the wind to strike the sails or vanes in the direction or at the angle requisite for producing the required speed. It also consists in the employment of a vertical rod for adjusting the wheel and rudder to the desired position with reference to each other. To the lower end of this rod I attach an arrangement by which a person standing upon the ground can easily shift the wheel or rudder to the desired position.

Referring to the accompanying drawing forming a part of this 1 specification, A is the frame which supports the mill, and B B the crossrtimbers, into which the lower end of the vertical hollow shaft 0 steps. The guide vane or rudder D is secured firmly to the top of the revolving shaft 0 by any suitable means so as to be stationary, and a circular flange, a, which forms the bed of the turn-table, projects at right angles from its top. The crankshaft b, to which the wheel E is attached, turns in boxes on the circular table F. This circular table is provided with a segmental and rod I, and through the rod the circular flange, e, which projects downward from the table F, thus placing the'wind-wheel atany outside rim, the inside of which is toothed, I desired angle to the'wind; and by drawing forming a segmental rack. This circular tadownward upon the opposite side, it 1s drawn ble is placed, as before hinted, upon the cir= back into line with the rudder, when, by letcular. flange a on the top of the shaft, thus ting goof the cordr, the pulley will fall byits forming a'turntable. On the lower end of own weight and engage with the coupling bethe vertical shaft 0 is a spindle or'horllow steplow, thus fixing the wheel at the desired angle. gndgeon, which steps into the metal plate f, to the rudder so that it uh have the same rel ative position to thewind, no difierence from which direction thewind comes or to which-it changes.

Having thus described my invention, what I claim, and desire to secure by Letters Pat cut, is--- 1. he table F with its projecting segmental rack e, turning on the flange a, in combination with the wheel E and rudder D', substantially as and for the purpose herein esoribed.

2. The vertical connecting-rod I, wind-wheel E, and rudder D, in combination with the toothed wheel Q, pinion g, pulley G, endless cord, and weights 1?, substantially as and for the purpose above described.

3. The pulley G with its toothed pinion g and under-pro ecting lugs or pins u, the same being raised by means of the curved lever L,

and operated by the endless cord '0 passing over pulleys N and O and kept taut by the weight P, substantially as described, for the purpose herein set forth.

4. In connection with a windmill having a slewing-rudder for the purpose of adjusting the wind-wheel to the wind, the rod I, applied substantially as described, for changing the relative position of the wind-Wheel and rudder from the ground, as set forth. In witness whereof I hereunto set my hand and seal.
