APPARATUS FOR FORCING WATER, &c., FROM NATURAL-GAS 0R OTHER WELLS.

SPECIFICATION forming part of Letters Patent No. 554,188, dated February 4, 1896. Application lil'ecl July 13,1895. ASerial No. 555,856. (No model.)

.To all whom t may concern.'

Beit known that we, JOSEPH K. JOHNSTON and WILLIAM B. JOHNSTON, citizens of the United States, and residents of Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Apparatus for Forcing Vater and other Liquids from Gas or other Wells; and we do 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, reference being had to the accompanying drawing, and to letters of reference marked thereon, which forms a part of this specication.

The ligure ofthe drawing is a vertical sectional view of the invention.

This invention has relation to apparatus for forcing water or other liquids from natural-gas wells, and is designed to provide means of improved character wherein the pressure of the gas is used to force the water to the top of the well.

The invention also provides means whereby the gas and water pipes may be cleared when necessary.

XVith these objects in view the invention consists in the novel construction and combination of parts, all as hereinafter described and pointed out in the appended claim.

Referring to the accompanying drawing, the letter A designates the drive-pipe of a natural-gas well, which is driven through the soil, sands, and drift tothe limestone rock upon which it rests, as indicated.

B designates the casing, which extends from the top of the well through the drive-pipe down to the shale rock upon which it rests, as shown. Below this pipe the rock constitutes the wall of the well. Said pipe is usually from five to five and five-eighths inches in diameter.

. O designates the water discharging or separator pipe, which extends from above the ground to the bottom of the well, its lower portion O being perforated to admit water.

c is a stop-cock at the upper portion of the pipe C.

D is the gas-pipe which surrounds the waterpipe O and extends from above the ground to the bottom of the well, its lower portion D being perforated. The upper end of the pipe D is connected by a coupling D2 to a pipe D3 D4, which is connected to a gas-main E which has other wells (not shown) also connected thereto.

F is a stufling or packing box for the pipe C, where it passes out of the coupling D2, said box having a nut F and packing f of hemp or like material, upon which the nut seats.

G is a small pipe which connects the pipe D3 with the pipe O and is for the purpose of admitting gas to the latter to blow it out whenever the perforations at the bottom thereof become clogged or choked.

g is a cock in said pipe.

g is a gate-valve in the pipe D3. I-I is a blow-oli for the pipe D, and h is th valve thereof.

I is a packer which is placed around the pipe B just above the line of the Trenton or gas-bearing rock, and which confines the water and gas below it.

The operation is as follows: By closing the gate-valve g/ and opening the valve c there will commonly be pressure enough in the well to force'the water into the pipe O and raise it to the surface and discharge it. It frequently happens, however, that after a well has been flowing for some time, the pressure of the gas becomes too weak to accomplish this result. When this occurs the valves c and g are opened, and the gas from the main E iiows down the pipe D into the bottom of the well, and being coniined below the packer D creates a pressure sufficient to force the water into pipe C and discharge it. The well being cleared of water the valve g is left open, and the gas in the well rises intothe main E.

By opening the valve g at any time the pipe O may be blown out.

By opening the valve 71. the pipe D may be blown out.

I-Iaving thusdescribed our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination of the gas-discharging pipe D, which extends to the bottom of the well, its lower portion being perforated and its upper portion connected to a gas-main IOO which is also connected to other Wells, the stantially in the manner and for the purpose Water discharging pipe O which extends described.

through the said pipe D to the bottom of the In testimony whereof We affix our signa- Well, and is perforated at its lower portion, tures in presence of Witnesses.
