WlNDMlLL-PUMP REGULATOR.

SPECIFICATION forming part of Letters Patent No. 560,243, dated May 19, 1896. Application filed November 25, 1895- Serial No. 570,066- (No model.)

To aZZ whom, it may concern:

Be it known that I, HARDER TREDE, a citizen of the United States, residing at Durant, in the county of Cedar and State of Iowa, have invented certain new and useful Improvements in lVindmill-Pump Regulators; and I do hereby declare the following'to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in windmill-pump regulators; and it consists in the arrangement and combination of devices which will be more fully described hereinafter,whereby when the water reaches the regulated height the windmill will be thrown out of operation and the pump stopped, and when the water has sunk in the tank to a certain point the mill will be thrown into operation again and the pump started.

The accompanying drawing represents my invention in side elevation.

A represents an iron standard, which is secured to the top of the well-cu rbing and which has its upper end curved or bent, as shown, for the purpose of throwing the pivot of the operating-lever any desired distance from its operating end. This standard A is braced rigidly in position by any desired number of brace-rods D. Pivoted upon the upper end of the standard A is the lever O, which has a screw-threaded rod D loosely attached in any suitable manner to its inner 'longerend, and which rod D passes through the screw-threaded perforated plate E, secured to the pumprod F, extending down from the windmill. By means of the screw-thread upon the rod D the lever O is made to work in unison with the rod F. The lever O is formed from a single iron rod or bar which is bent double, so as to receive the upper en d of the standard between its two sides. Also secured to the standardA is the metallic frame G, of the shape shown, and which is also made double, so as to allow the various operating parts to be pivoted between its two sides. Rigidly secured in between the two parts of this frame G is the guidin g-rod II, which extends down along the edge of the ratchet-bar I, which has its vertical movements between the rod and the standard The ratchet-rod I being guided or held bestop the mill and to allow it to swing around again at right angles to the wheel when the pump is to be again started. The construction of the wheel by which the ratchet-rod is enabled to operate the vane forms no part of this invention, and is therefore not shown.

Pivoted to-the outer shorter end of the lever 0 is the pawl K, which engages with the ratchet-rod I when the wheel is to be stopped and which remains out of contact with the rod I until the tank has become filled, when it is moved into engagement with the ratchetbar for the purpose of forcing it downward. Loosely connected to this pawl K is the rod L, which is also loosely connected at its outer end to the rod M, which has its upper end to pass through an opening in the vertical lever N. The lever N and the float-lever 0, while extending at about right angles to each other, are practically made of one piece and are pivoted between the outer portion of the frame G, so as to be operated together. Through each end of the vertical lever N is made an opening, and through the openin gin the lower end is the rod P, which isprovided with a stop Q. The inner end of the rod P isconnected with the pawl R, which engages with the ratchet-rod I simultaneously with the pawl K and for the purpose of preventing the ratchet-rod from moving upward while the pawl K is engaged in forcing it downward for the purpose of stopping the pump.

The rod M has its inner end attached to the pivoted lever S, which is pivoted upon the frame G and which engages with the curved pivoted stop T when the stop has been drawn downward by the rising of the water in the tank and the elevation of the outer end of the lever 0 thereby.

The rod M is provided with a stop U, and between this stop and the upper end of the lever N is placed the spring V, which serves to keep the upper end of the lever S pressed inward when the curved stop T is drawn downward, whereby the lower end of the lever S is made to catch upon its top and hold the lever N O in a raised position. As the float in the tank descends the levers O N are turned upon their pivot in the frame G and the upper end of the lever N moves outward, when the rod M is moved by the reaction of the compressed spring U so as to change the inclination of the lever S, and thus move its lower end from the outer end of the curved stop '1. This stop is provided with a shoulder upon the top of its outer end, and upon the top of this shoulder the lower end of the lever S is made to catch when the lever N is made to assume a vertical position by the rising of the float in the tank. Until the water descends a certain distance in the tank the lever S remains upon the top of the stop T; but when the water has sunk to a certain level the dropping of the outer end of the lever O and the changing of the inclination of the lever N causes the lower end of the lever S to move inwardly off of the top of the shoulder, and then the stop has its lower end raised by the spring \V, placed upon the connecting-rod X between the end of the stop and the inner end of the lever O. The lower end of the rod X is free to move through the inner end of the lever 0, so that when the outer end of the lever O is lowered by the falling of the float in the tank the spring is compressed against the lower end of the stop T.

\Vhen the float in the tank has sunk to a certain level and the outer end of the lever O has been lowered and the lever N is moved from a vertical to an inclined position, the pawl K is drawn out of contact with the ratchet-rod I and the lever S is moved from over the shoulder of the stop T, the red I is released, and then the vane swings around at right angles to the wheel and the pump starts into operation again. lVhen, however, the float in the tank raises the outer end of the lever O, the pawls K R are thrown into operation with the ratchet-bar I, and then the movement of the lever (J forces the bar I downward until the vane is swung around into a line with the wheel and the pump is stopped.

It will be seen from the above that the operation of my invention is entirely automatic and that when the tank is full the pump is stopped and when the water falls to a certain level the pump is automatically started into operation again.

Having thus described my invention, I,

claim.-

The pump-rod, the screw-threaded rod D, adj ustably connected thereto, the standard, the lever C, connected at its outer end. to the rod D, and pivoted upon the standard, combined with the frame G, secured to the standard, the lever N, O, pivoted upon the frame, the tank, and the float therein connected to the lever N, O, the two rods L, I, the two pawls K, R, pivoted to the inner ends of the two rods; the ratchet-rod I, connected to a part of the windmill and with which the pawls engage; the rod M, connected at its outer end to the rod L, and passing through the lever N, the lever S, pivoted upon the frame and operated by the rod M, and the stop T, pivoted upon the frame and connected to the inner end of the lever O, the rod M and stop T being provided with springs, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

HARDER TREDE.
