IMPROVEMENT IN WINDMILL-REGULATORS.

Specification forming part of Letters Patent No. 145,765, dated December 23, 1873; application filed August 13, 1873.

the wind-wheel and vane. Fig. 2 is a sectional view, illustrating my improvement for governing the mill. Fig.,3 is a top view of Fig. l.

Similar letters of reference indicate correspoutling parts in the three figures.

This invention relates to an improvement for regulating Vautomatically that class of windmills the vaues of which are pivoted to the caps of the mill in 'such manner as to swing horizontally and change the faces of the windwheels, so that they will edge7 more or less to the wind, according to the force thereof. My object is to employ, in combination with a windmill of the description above named, and with the pump thereof, a chamber which communicates with the interior of the pump above the `piston, and in which is a piston whose rod is connected with a gravitating-arm, to which the vane of the mill is attached, so that the surplus water, or that which cannot escape through the pump-nozzle, shall operate to regulate the speed of the mill, as will be hereinafter explained.

The following'description of my invention will enable others skilled in the art to understand it.

In the accompanying drawings, Arepresents the cap ofthe mill-tower, through which passes a hollow turning-center, B, the upper end of which is flan ged and supported upon anti-friction balls h. On this center B is formed a bearing, Gr, through the tubular portion of which passes the shaft of the wind-wheel E, on the inner end of which shaft is keyed a crank-wheel, e. To a wrist-pin on the crankwheel e is attached a rod, f, the lower end of which is connected to the upper end of a short grooved rod, C, by a pivot, g. The lower end of this grooved rod C has a ball, o, formed on it, which is received into a socket formed on the upper end of the pump-rod D, and through which a hole is made vertically. The rod l) passes down into a pump-stock, l), and has a piston or valve-bucket, t,4 secured to it, for raising water and forcing it out of cock or nozzle r. The pump rests on a platform, It, and alongside of it is a vertical surplus-water cylinder, N, which communicates with the interior of the pump above the piston tby means of a passage, y, as shown in Fig. 2. The cylinder N is open at its bottom and closed at its top, except the passage y, leading into the pump; and inside of this cylinder is a piston, m, the rod l of which rises through the cylinder, and has connected to it a rope or chain, k, which passes up, through the rod O and turning-center, to and over a pulley, 1'., on bearing G, and is attached to an arm, W. This arm W is pivoted at j to the bearing G, and its outer end carries an adjustable weight, W. F represents the vane ofthe mill, which is pivoted at s, (see Fig. 3,) so as to swing horizontally. tically-vibrating gravitating-arm V by means of a rod, p', which is pivoted at q p. Other means than those above described may be adopted for connecting the vane to the pistonrod l, although for simplicity I prefer these means.

It will be seen from the above description that when the speed of the mill is so great as to raise more water than can pass through the cock r the surplus water will flow into the cylinder N above the piston m, and by the weight of this water and the force of the piston t the piston m will descend, carrying with it the rod l and raising the loaded arm WV more or less. The effect of this descent of the piston m is to change the angle of the vane F with respect to the face of thc wind-wheel E and retard the speed of the mill. If the force of the wind is such as would be lia-ble to break or derange the mill-works or the pump, then the piston m will be forced so low as to move the vane around parallel to the face of the wind-wheel, as indicated in dotted lines, Fig. 3, and thus throw the wind-wheel out of the wind.

By means of the cock r the discharge from the pump can be regulated or entirely shut, in which latter case the mill will stop.

It is obvious that my invention is applicable This vane is connected to the verto double-acting pumps, :is Well as to the single-acting kind.

I am aware of the patent of Waiter S. Peck, granted June 19,1860, which shows an atmospheric governor, consisting of an air-pump with regulating-cock, for controlling the vaines of a Wind-Wheel, and therefore I do not claim, broadly, a pump for controlling the venes of 2L Wind-Wheel; but

H :win g described my invention, what I claim es new, and desire to secure by Letters Patent, 1s-

A surplus-Water cylinder, N, communicating with che interior of a pump, and having a piston Working in it which is connected to a vane Workingmeohanism, substantially as described.
