GEORGE IV. HAYS AND GEORGE E. SANDERSON, OF AUBURN, NEBRASKA.

PUMP.

SPECIFICATION forming part of Letters Patent No. 553,808, dated January 28, 1896.

Application filed September 5, 1895. Serial No. 561,509. (No model.)

To all whom it may concern:

Be it known that we, GEORGE IV. HAYS and GEORGE E. SANDERSON, citizens of the United States of America, residing at Auburn, in the county of Nemaha and State of Nebraska, have invented certain new and useful Improvements in Pumps; and we do hereby declare the following to be a full, clear, and exact description of our invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters of reference marked thereon, which forms a part of this specification.

The object of this invention is to provide a pump of improved construction, whereby at each upstroke of the piston'rod air will be forced to the bottom of the water-chamber and assist in forcing the water out of the dischargespout as well as aerate the same; and with these ends in View the invention consists in the construction and combination of the parts, as will be hereinafter fully set forth, and particularly pointed out in the claims.

In the accompanying drawing, forming part of this specification, the figure is a side elevation, broken away at intervals to better show the interior construction.

A designates the pump stock or cylinder through which the upper end of the piston rod passes, and this cylinder is supported so as to extend a suitable distance above the platform aby means of a casting a, said casting being provided with an extension through which the dischargepipe M of the pump passes. The upper end of the cylinder A has secured thereto a head or cap a constructed to provide guides for the piston-rod E and pump-handle A, the pump-handle being connected at its inner end to the piston-rod and fulcrumed upon a. vertical bar a secured at its lower end to the casting a and braced by a fixture a projecting from an intermediate portion of the cylinder A. The upper end of the piston-rod extends above the head or cap a and may be provided'with any suitable means for connecting the same to the operating-rod of a windmill.

To the lower end of the cylinder A is coupled an air-chamber B which is connected with an air-inlet pipe 0 provided with a checkwalve O. This air-inlet pipe is located beneath the platform a, and the check-valve therein permits the air to enter the chamber 13 and prevents its backward flow. Through the air-chamber B the piston-rod E passes, and this piston-rod is hollow and is provided within the chamber B with a coupling G having a check-valve g, the piston-rodbeingprovided with holes or inlet-apertures 6 above the coupling G. Upon the piston-rod below the coupling G and within the cylinder or chamber B is secured a piston D having the usual packing-rings d and d.

F designates the upper part of the watercylinder which is coupled to the lower end of the air-chamber B and is provided with an exit-pipe L coupled to the discharge-pipe M. The exit-pipe L may be provided with a short section Z, to which a pipe for carrying the water to a distance may be attached, and when this is provided the upper end of the discharge-pipe M has a cut-offvalve a I designates the lower part of the watercylinder in which the piston H moves, said piston being attached to the lower end of the hollowpiston-rod E. The lower end of the part I of the water-cylinder is provided with an ordinary valve J, through which the water passes from the well into the water-cylinder. The frame of the piston H is provided with a series of holes h which communicate with the open lower end of the piston-rod, and said piston is also provided with an ordinary valve.

In operation when the piston-rod E is on its downward movement the valve J is closed and the water contained in the cylinder I is forced above the piston H, and at the same time the piston D draws a quantity of air into the chamber B through the inlet-pipe O, and also forces the water which has collected below the piston out through the dischc rgepipe. Now upon the upstroke of the pistonrod the piston II forces the water out of the .discharge-pipe, and at the same time the piston D forces the air contained in the chamber B into the hollow piston-rod and out of the lower end thereof, so that it will not only assist in discharging the water but also aerate the same, the check-valve in the coupling G preventing suction in the hollow piston-rod when the piston D descends.

IOO

llavin g thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a pump, the combination, of a pump stock or cylinder A suitably supported and provided at its lower end with an air-inlet valve; an air-chamber B connected to the lower end of the cylinder A and communicatinwith the inlet-valve, and awater-cylinder coupled to the lower end of the air-chamber; together with a hollow piston-rod E having pistons located in the air and water chambers and provided with a check-valve, the hollow piston-rod opening at its lower end into the water chamber or cylinder and having holes or apertures e which communicate with the air-chamber, substantially as shown and for the purpose set forth.

2. The combination in a pump, of a cylinder A suitably supported; an inlet-pipe 0 connected to the lower end of the cylinder and provided with a check-valve; an air-chamber B coupled to the cylinder and communicating with the inlet-pipe, and a water chamber or cylinder coupled to the air-chamber, the water-cl1a1nber having a valve at its lower end; together with a hollow piston-rod E having pistons operating in the air and water chambers, and a coupling G connected to the piston-rod within the air-chamber; the hollow piston-rod opening into the lower end of the water-chamber through holes in the frame of the piston therein and provided with holes c communicating with the air-chamber, substantially as shown and for the purpose set forth.
