Wind-Mill.

FRANK G. QHARLES, OF GALESBURG, ILLINOIS.

IMPRVEMENT IN WINDMILLS.

Specification forming part of Letters Patent No. 131,426, dated September 17, 1872.

To all whom it may concern:

Be it known that I, FRANK G. CHARLES, of Galesburg, in the county of Knox and State'of Illinois, have invented a new and `useful Improvement in Wind-Wheels; and I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon and being a part of this specification, in which- Figure l is a vertical longitudinalseetion of the wheel and attachments. Fig. 2 is a plan of the operative parts. Fig. 3 is an elevation of the swivel and spider.

Like letters refer to like parts in each figure.

rlhe nature of this invention relates to an improvement in that class of wind wheels which is employed for pumping water; and has for its object to provide an automatic device for throwing the sails out of wind when thetank is lled, and to so pivot the said sails to their hub that, in combination with the governin g device and a iioat, they will ease up y out of the wind when blowing hard. The invention consists in the peculiar construction and arrangement of the several parts for the 'everal purposes, as more fully hereinafter set orth. c

In the drawing, A represents the Wheelshaft, journaled in bearings in a bracket, B, revolving in a tubular vertical support, C. D is the vane secured to the opposite side of the bracket. E is the hub secured to the outerend of the 'shaft A. In the periphery of this hub are pivoted the arms F of the sails Gr, which are secured to their arms so as to have a little more area on the side of the arm toward the vane,

so that the tendency of the wind would be to bring the sails edgewise to it. His a connecting-rod, pivoted to a crank at the rear end of the shaft A and to the piston-rod of a pump below, (not shown.) I is a spider, sleeved on the shaft behind thewheel, with an arm for each sail, to which it is connected at the front side by a link, a, pivoted at the other end to an arm, b, projecting from the front side of the sail, near its base and behind its axis. On the back of the spider is a swivel, I', with which engages a yoke, c, to which is pivoted a forked rod, d, sliding in bearings on top of the bracket. J is a vertical standard on the vane-arm, to which is pivoted alever, K, weighted as at L. This lever K is forged with two arms, the vertical one, e, rising from the fulcrum, and a horizontal one, f, on a prolongation toward the wheel. The top of thearm e isV connected, by a rod, g, to the forked rod, which is in turn connected to the spider. M is a iioat whose weight is graduated tothe size of the wheel, and is suspended in the tank by a rod, h, from the end of the arm f of the lever K, said rod passing up through the tubular support G. lWhen the float M is buoyed up by the water rising in the tankV the weight L, drawing back the spider through its con.`

nections, rotates the sails G so as to bring them edgewise to the wind, when the wheel will cease to revolve. When thewater is drawn down away from the float the latter overloalances the weight L, so as to bring the faces of the sails athwart the wind, at an an;

gle with its course.

During the prevalence of a gale, by reason of the eccentriepivoting of the sails, the latter are more or less rotated on their axes, brin ging them in the plane of the course of -the wind, consequently reducing the speed of the wheel and necessarily lifting the oat M from the water. If the float be heavily weighted the higher will be the speedof the wheel, as more power must necessarily be exerted upon the sails to lift it.

What I claim as my invention, and desire to secure by Letters Patent, is

The construction and arrangement, with relation to the shaft A, bracket B, tubular support C, vane D, hub E, arms F, and sails Gr, of the spider and swivel I I', arms b, links a, yoke c, connecting-rods d g, weighted bellcrank lever K, standard J, rod h, and iioat M, substantially as and for the purpose set forth.

FRANK Gr. CHARLES.
