Letters Patent No. 114,989, dated May 16, 1871; antedated May 12, 1871.

IMPROVEMENT I N PUMPS.

The Schedule referred to in these Letters Patent and making part ofthe lame.

To all whom it may concern v Be it known that I, ZARA.T. SWEET, of Tiskilwa, in the county of Bureau and in the State of Illinois, have invented certain new and useful Improvements in Railroad and Stock-Pumps; and do hereby declare that the following is a full, clear, and exact description thereof; reference being bad to the accompanying drawingand to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arrangement of a railroad and stockpump, as will be hereinafterfully set forth;

In order to enable others skilled in the art to which my invention'appertains to make and use the same, I will now proceed to des'clibe its construction and operation, referring to the annexed drawing, in which-- Figure 1 is'a side view of my pump, the cylinder being in vertical section.

Figure-2 is a section of the same.

-- A A represents the pump-cylinder, provided with a convex bottom, B, in the center of which is a ballvalve, a; r

Above and around this valve are guides 11 b, to'pre vent'the same from rising too far and getting out of place.

The upper end of the cylinder A is conical-shaped,

and-from its apex leads a pipe, D, upward, as shown.

. Inside-of the cylinder A is placed the plunger or piston G,- which is also provided with a ball-valve, a-',

and guids b for the same.

The plunger-rod E extends up through the pipe D,

and when the pump is in operation the water is drawn up around said rod through the pipe, and may be made to flow into a reservoir, trough, or any other suitable receptacle;

On the rod E, above the upper end of the pipe D, is placed a loose collar or ring, d, which may be adj usted at any height by means of nuts 0 0, one above and one below, this portion of the rod being provided with screw-threads for that purpose.

Above the upper nut 0, around the rod, is placed a spiral spring, f, the upper end of which bears against that portion of the frame-work through which the rod passes, and which acts as a guide for'the plunger-rod. The action of this/spring f is to throw the plunger or piston 0 down after it has been raised.

The cylinder A is placed in the bottom of a well,

and the pump may be operated by hand or by the foot,

or by a train of cars passing, or by cattle or other stock, as will be presently described.

To the collar d is attached a lever, G, which is suspended or pivoted in the frame-work above the pump, the other end of said lever being, by a chain, y, connected with a grooved wheel, H, on a shaft, h. On this shaft is a cam, I, placed at the side of a railroad track.

Onthe side of the cars there is attached a bar, 7: with a friction-roller, i, which strikes the, cam I and turns the shaft 11.. This, operating through the lever G raises the pump-plunger, carrying with it a' quan tity of water. In this manner one train may be made to pump up the water necessary for the next train.

When it is desired to l 1ave the pump operated by the cattle coming to drinkat troughs or other convenient receptacle placed at the mouth of the well, I propose to have an inclosure around the same. In the opening or passage to said inclosure is a hinged platform, J, connected by chains or rods-g'with another lever, G, which is also connected with the collar d. The cattle or any other stock passing over the platform J will' thus pump up water for themselves.

The pump may also be operated or worked by hand, or by a foot-lever, if so desired.

The levers employed may be either straight-0r elbow- I levers, or several combined. I do not confine myself to any particular shape or form ofthe same.

Having thus fully described my invention,

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

l. The arrangement of the shaft 71 cam I, wheel H, chain g, and lever G, substantially'as shown and described, for operating a pumpby a passing train of cars, substantially as herein set forth.

2. In combination with the shaft h, cam I, wheel H,- chain 9, and lever G, plunger E, pipe D, and cylinder A with its valves, all constructed to operate substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 7th day of October, 1870.

ZARA T. SWEET.
