DAVID LIPPY, OF MANSFIELD, OIIIO.

PUNIP.

SPECIFICATION formingpart of Letters Patent No. 574,252, dated December 29, 1896.

Application filed December 28, 1895. Serial No, 573,648. (No model.)

To all whom t may con/cern:

Be it known that I, vDAVID LIPPY, a citizen of the United States, residing at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Iumps; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexe-d drawings, making a part of this specification, 'and to the letters of reference marked thereon.

The present invention has for its object to improve in the several details of construction that class of submerged pumps provided with a hollow plunger-rod and plunger; and it consists in a pump constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure l of the drawings represents a sectional elevation of a pump embodying myinvention; Fig. 2, a horizontal section taken on line fr of Fig. l.

In the accompanying drawings, A represents the pump-cylinder, and B C two contracted ducts which are disposed diametrically opposite each other, as shown in Fig. 2 of the drawings. The ducts B O are cast with and form a part of the cylinder A, or the ducts are connected to the cylinder in any other suitable manner as found best adapted to the purpose, this being left discretionary with the manufacturer, or, if preferred, the ducts may be formed of tubing secured to the cylinder at the top and bottom thereof. rlhese ducts communicate with the cylinder at the top and bottom, as shown in Fig. 1 of the drawings, suitable coupling-heads D E having exterior screw-threads to engage the screw-threads on the flanges ce at the ends of the ducts D O and the screw-threads at the ends of the cylinder A.

The coupling-head E at the lower end of the pump-cylinder A forms a seat for a suitable valve F, which valve controls the central opening Z) for the passage ofthe water into the cylinder.

The ducts B C communicate with the central opening'b and with the interior of the pumpcylinder through the holes c, which holes extend through a groove cl around the exterior of the coupling-head E, as shown.

The coupling-head D comprises the two disks ef, joined by a central tubular neck g, said disks having exterior screw-threads with which the screw-threads upon the upper ends of the du cts and pump-cylinder engage. The disk e has an upwardly-extending iiange to form a cup-shaped receptaclej for a suitable packing h and a screw-threaded washer t' to hold the packing in place. The cup-shaped receptacle has interior screw-threads withy which engage the screw-threads of the washer and the screw-threaded end of thedischarge cylinder or pipe G. The disk f has openings 7o for the passage of the water, said openings being controlled by a suitable valve II upon the under side of the disk.

The tubular or hollow plunger-rod I has openings Z through its side for the passage of the water into the cylinder or pipe G, and the lower end of the rod has connected to it a water-chamber K by means of the screw-coupling m. This water-chamber K has openings n at its top for the passage of the water from the pump-cylinder into said chamber, said Openings being controlled by a suitable valve L.

'Io the under side of therwater-chamber K is secured the short pipe N, which forms a continuation of the hollow piston-rod, and which serves to connect the two water-chambers K M. The chamber M is longer than the one K and has the packing o secured to its upper end in the chamber formed between the two chambers. The chamber M has also a packing p applied to its lower end, while the chamber K has none applied to it. In the lower end of the chamber M is secured the valve-seat r, upon which is supported the valve O,which controls the opening S, through which water passes from the cylinder into the plunger on its downstroke.

The valve L in the upper chamber K serves to prevent the water from escaping from the' IOO vided with valved openings in their outer ends, a contracted neck for uniting the 'cylinders, two hollow pistons provided with valves at their outer ends, a hollow piston-rod divided into sections, a disk secured to the piston-rod, and a packing on the disk, for this is shown in my pending application iled December 28, 1895, and bearing serial number 57 8,647

Having thus described my invention, I claim- In a pump, a single cylinder provided with a Valve at cach end, a hollow pistonrod, a piston having a water-chamber at each end, and a valve in the outer end of each chamber, and

of two witnesses.
