UNITED STATES PHILIP A. MYERS, OF'ASHLAND, OHIO.

WlNDMiLL-PUMP REGULATOR.

SPECIFICATION forming part of Letters Patent No. 501,354, dated July 11, 1893.

Application filed May 4, 1892. Renewed March 31. 1893. Serial No, 468,578. (No model.)

To on whom it may concern.-

Be it known that I, PHILIP A. MYERS, a citizen of the United States of America, residingat Ashland, in the county of Ashland and State of Ohio, have invented certain new and useful Improvements in Windmill-Pumps, of which the following is a specification.

The serious defect in the ordinary Windmill pump, in which hydraulic pressure is made to turn the wheel out of the wind, is the great strain put upon the pump. This pressure strains the valves and packings, and tends to disable the pump, more than the ordinary work to which the pump is subjected.

The object sought in my invention hereinafter explained, is to avoid the excessive In ordinary windmill pumps hydraulic pressure is used directly to turn the wind wheel out of the wind, and the pressure is continued until the Wheel is turned out. This requires a large amount of movement and force. This force is exerted during the movement of the wheel out of the wind, and, (especially in high winds) during some movement by momentum afterward, so'that there is long continued as Well as additional and unnecessary pressure caused by this movement, and from this the injurious strain results. I have sought to remedy this defect, first by releasing the pump rod from the windmill, immediately upon the closing of the discharge valve, and secondly by providing detachable connection between the windmill and its pitman, by means of which the Windmill, acting independentlyof the pump and free from it, turns itself out of the wind. This connection between the pitman of the engine, and the wheel turning device is normally detached and is so held, but is restored when the other is released.

I do not herein claim broadly a removable connection between the windmill pitman, and the pump rod, with a hydraulic device for removing such connection, such a combination being shown in the application filed by me in the United States Patent Office on the 16th day of April, 1892. In that application I have shown a detachable connection and a hydraulic device, having permanent connection with the wire which draws the wheel out of the wind, but in that construction the work of turning the wheel out of the wind, is still left to be done by the hydraulic pressure.

In my present invention, the only work done by the hydraulic apparatus consists in releasing the device by which the pump rod is connected to the pitman of the wind engine, and in permitting the connection to be made between the said pitman and the device through which the wheel is drawn out of the wind. Substantiallytheonlyexertion offorce required is forthe releasing aforesaid, and as this is very small the work may be performed upon the first abnormal increase of pressure in the pump, when the valve in the tank is closed. I

My invention therefore consists primarily of a detachable connection between the pump rod and the pitman of a wind engine, combined with detachable connection between said pitman and the device for drawing the wheel out of the wind, and with controlling devices for both connections operated by a dydraulic pressure device.

The invention includes also details of construction, of a simple and efiiective form, in which I have embodied my invention, but to which I do not limit my claims, as I am aware that these details may be changed without departing from the spirit of the invention.

Thisinvention I have illustrated in the accompanying drawings, in which- Figure 1, shows the pump in side elevation. Fig. 2, is a side view, a quarter turn from Fig. 1. Fig. 3 is a detail view of the connection between the pump rod and the wind mill pitman, with the spring frame thrown back.

The pump shown is one of a well known construction in which is a forcing chamber, and it is designed to have a pipe leading to a tank having a valve and valve operating mechanism, for closing the pipe when the tank is filled, that being also well known.

Upon one of the castings A, in which is a passage leading to the forcing cylinder (not shown) is a' pressure cylinder B. This is fixed, and provided with a piston a, having a piston rod 1), which extends through the base 0, of the 'pump.. About the upper end of this rod is a spring 0, the lower'end of which bears upon an adjustable coller d, and the upper bears against the under side of the base, the spring being of sufficient'force and so adjusted by the collar, that it will return the piston to the bottom of the forcing cylinder upon the cessation of the abnormal pressure of the water, due to the clearing of the discharge pipe. The upper end of the rod 1) is connected by link 6, to a sliding bar F which has inclined slots fif, in which are pins g g, one set in a collar on the pump stock, and another on an arm h on the main bracket H, on which the pump handle is pivoted. This arm may be cast with the said bracket.

On one side of the bar F, is an extended straight edge F, which bears against the pin 2, in the locking arm between the pitman and pump rod, and when the bar F is pushed up, the inclined slots, working on the pins, force it forward toward the pin 2, and release the connection between the pitman and the pump rod. On the other side of the bar is another extended straight edge F. This extends over the side of a bar G, which slides vertically in guides, one of,'these being an extension of the main bracket H, and the other formed by a hole in the pump base. The outer edge of the bar G has ratchet teeth, the inclined faces of which are on the lower side. This bar G is operated by a pawl 7c, carried on the outer end of a lever K. The pawl is held to its work by gravity, having a weighted arm 5, but it maybe held bya spring. The holding pawl Zis similar, and is pivoted on an extension of the bracket H. The lever K is connected by a rod m, with the lower end M, of the wind engine pitman, so that the lever K is constantly operated when the engine is in motion, but without effect, except when the pawls are in gear with the bar. The bar F, is so arranged that when the edge F is drawn back, and connection is formed between the pitman and the pump rod, the other edge F is extended beyond the ratchet bar G, far enough to hold the pawls out of gear. This is the normal condition and the result of the forcing piston being down. In this condition the pump is at work. The bar Gis connected through a wire and spring, with the lever which pulls the wheel out of the wind,adevice well known. When the pawls are in gear the lever operates the push pawl and forces down the bar, which thus draws the wheel out of the wind. Thus it will appear that the bar F acts alternately on the pawls and the connection between the pump rod and pitman. When not holding the look ing pin on the pitman, out of connection, it holds off the pawls and the reverse. The return of the bar F,is immediate upon the fall of the water in the tank, and is caused by its own gravity, and the spring underneath the base. The instant therefore the pressure falls, the pump and engine are at once put in connection.

The detachable connection between the pitman and the pump rod, is made by means of a frame P. This may be cast in one piece with the side bars, end pieces and guide as shown. On the upper end of the frame is a spring arm 19, which presses thereon. The frame carries a dog q, adapted to enter a notch in the edge of the pitman bar. A pin 2. on the arm 19 is in range of the edge F and operated upon by said edge as above explained. In order that the frame may not fall below range of the lug, I have placed a spring 15, on the rod, this spring resting on the base and bearing upon the lower end of the frame.

While I have shown a pressure device in the form of a cylinder and a piston as better fitted for the special combination I do not limit myself to this particular form.

As a matter of safety the wire leading from the spring on the bar of the wheel, by which the wheel is turned out of the wind, should be carefully adjusted to the proper length, so that the wheel will be out of the wind, when all the notches have been used by the push pawl, the retaining pawl holding it in that position.

I claim 1. In a windmill pump, a detachable connection between the pitman of the wind engine, and the pump rod, a detachable connection between said pitman and the device for drawing the wheel out of the wind,and a hydraulic pressure device, arranged to operate both of the said detachable connections,substantially as described.

2. In a wind mill pump, a detachable connection between the pitman of the wind eugine and the pump rod, a movable bar actuated by the pitman, aconnection between the said barand the device which draws the wheel out of the wind, and a bar operated by the pump pressure, and arranged to control the detachable connection to the pump rod, substantially as described.

3. In combination with the detachable connections between the pump rod and the pit man, and with the detachable connections between the movable bar G and the pitman, a bar as F having edges arranged to control said connections, a pressure cylinder connected to said bar F, substantially as described.

4. In combination with the detachable connections between the pump rod and the pitman, and with the detachable connections between the movable bar G and pitman, a bar F, havinginclined slots and arranged on fixed pins said bar having straight edges arranged to bear upon the said detachable connections, a pressure cylinder connected to said bar F, and a spring to return the said bar when the pressure of the cylinder is removed, substantially as described.

5. In a wind mill pump, a detachable connection between the pitman of the wind engine, and the pump rod, a detachable connection between said pitman and the device for drawing the wheel out of the wind and a bar arranged to control both of the said connections, substantially as described.

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

PHILIP A. MYERS.
