SPECIFICATION forming part of Letters Patent No. 309,645, dated December 23, 1884:.

Application filed January 26, lFSl. (No 1nodel.l

0 all whom it may concern:

Be it known that we, Greene-n W. Oncu'rr and James A. Wool), of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved \Vindmill, of which the following is a full, clear, and exact description.

The principal object of our invention is to provide a windmill or" simple, inexpensive, and durable construction, and which shall be self-regulating against variations of centrifugal force and windn'essnre;

The invention consists in the construction and arrangement of parts, as will be hereinafter described and claimed.

Reference is to be had to theaccompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a central vertical sectional elevation of our improved windmill, showing the connections for driving a well-pump. Fig. 2 is a plan view of the same, and Fig. I is a horizontal sectional. view on line a," :0, Fig. 1.

The letter (1/ indicates a substantial frame or tower, in which the wind-wheel of the mill is journaled by its central post, I), at c in a top cross-bar and at (Z in a strong sill-timber, as shown. We make the center post or vertical axis, I), of the wheel in square or angular cross-sectional form, to afford a bearing for the parts of the wheel mounted on the post and which are to turn with the post.

The wind-wheel consists, mainly, of upper and lower frames, 6 f, made preferablyin circular form, and fitted on the post I), and having the fans, sails, or wings g pivoted at their outer edges between the frames on the rods or bars it. The inner or free edges of the fans {1 are connected by strong rods t with a central frame or wheel, j, which we call the governor of the mill. The governor j has loose bearings on the post 6, so as to slide up and down freely on the post as the wind-wheel revolves.

Rising from the governor j, and fixed to the same at their lower ends, are two rods or bars, 7a, which are preferably bent inward toward each other at l, and carry fixedly at their tops the horizontal ring plate or disk in. which rises and falls with the governor.

On a cross-bar of the frame a we pivot or fulcrum at a a swing-frame of parallel bars 0, having anti-friction rollers 12 journalcd thereon directly below the disk at, and extending outward to the side of frame a, where said bars 0 are connected by a cross-bar, r, to which is connected a cord, rope, or chain, 8, passing upward over a sheave or pulley, 2, and then downward through any suitable guide-staples within reach of the attendant, so that by drawing on rope e the rollers 19 will be raised against the revolving disk on to raise it and lift the governorj,and cause the rods t to close the fans or wings g of the wheel when the mill is to be stopped, and when the mill is to run the rope s is unfastened to let the frame-bars 0 drop against a cross-bar of frame a, or any suitable stop, to allow fans fully to open, in which position the inner or free edges of the fans rest against the periphery of the governorj, shown.

The action of the windavhecl is as follows: The wind striking the concave faces of the fans 7 will cause the wheel to revolve, and when the speed reaches a certain limit the centrifugal force will act to close the fans independently of the action of the wind thereon. The fans in closing lift the governor j by the rods 7 and by weighting the governor more or less the speed of the wheel may be controlled. Any overpressure by an increased wind force also tends to partly close the fans and lift the governor, and the mill will continue to run at an even speed in violent wind-storms. The speed ot'the wheel is determined wholly by the velocity, any tendency to excess of speed acting through the governor to partially close the fans,'and when the wind force decreases the weight of the falling governor will gradually open and hold the fans, to maintainthe uniform speed for which the governor is set. It will thus be seen that byavery simple construction and arrangement of parts we provide a wind-wheel which closely regulates itself as to speed against variation of centrifugal force incident to the connection or disconnection of any of the machinery which may be driven by the mill, and also against variations of wind force. By pivoting the fans g at their outer edges the wind has a driving effect on the wheel IOO the well-pump.

as it leaves the wheel as well as on entering the wheel.

The mill is stopped by drawing upon and securing the rope s, as above described. The lower step-bearing, d, only requires oil, which may be supplied to it by an oil-cup, a, one filling of which will last for a long time.

Power may be taken from the wheel-shaft b by any system of wheel or belt gearing for driving general machinery; but we have de vised a simple plan for giving motion to the working-lever o of a rod, '10, working a pump ina well, x, for which purpose we connect to the shaft b, one over the other, a couple of shafts or axles, a, on which revolve freely the anti-friction wheels I), which as the shaft turns act on opposite sides of a plate or disk, 0, fittedlooscly around and free from the shaft, and fixed rigidly to'the lever 11 at d in oblique po "sition, so that the rotation of the shaft causes a rocking of lever 12 on its fulcrum c, to work I The action of the wheels I) and disk 0 is positive and noiseless, and the power is taken to work the pump very near the shaft 1), and lateral strain upon the shaftbearings and on the mill-frame is thereby avoided.

The movements of thelever 11, its disk 0, and the wheels I) are clearly indicated in full and dotted lines in Fig. 1.

lVe propose to make the fans g of sheet metal and coat them'with weather-proof paint to insure durability.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a windmill, the combination, with the pivoted fans 9, governor j, and rods 13, con necting the fans with the governor, of the rods 70, disk or plate m, swing-frame bars 0, having anti-friction rollers 19, and the rope or chain 5, arranged for lifting the governor to close the fans and stop the wi ndwhcel, substantially as shown and described.

2. The combination, with the wind-wheel 5 shaft 6, provided with the two axles a aone above the other-and rollers b b thereon, of the pivoted lever 21, provided at its inner end with the inclined centrally-perforated disk c, said disk passing loosely around the shaft 1) and between the two friction-rollers, whereby when the wind-wheel shaft is rotated the lever 12 will be positively operated both in its upward and downward movement, substantially as set forth.
