CHARLES 1?. HOWE, OF WALTERS, OKLAHOMA,

WORKING BARREL.

Application filed September 20, 1924. Serial No. 735,934.

To all whom, it may concern:

Be it known that I, CHARLES P. Hows, a

citizen of the United States, residin at Walters, in the county of Cotton and tate of Oklahoma, have invented certain new and useful Improvements in Working Barrels, of which the following is a specification.

This invention relates to working barrels especially adapted to be used in oil wells, and it consists in the novel features hereinafter described and claimed.

An object of the invention is to .provide a working barrel or pump of simple and durable arrangement aving its arts and features so assembled and associated that gas, oil, and other fluids may be readily pumped out of the well, without the use of tubing, other than the regular casing in thewell. I

In the accompanying drawing:

Figure 1 is a vertical sectional view of the working barrel.

Figure 2 is a transverse sectional view thereof, cut on the line 22 of Figure 1.

As illustrated in the accompanying drawing the well casing is indicated at The working barrel comprises a cylindrical fitting 2, provided at one end with a n pple portion 3, and at its opposite end with a nipple portion 4. The nipple ortion 1 is of greater diameter than the nipple portion 3. Passageways 5 pass longitudinally through the fitting 2 and communicate at their lower ends with the interior of the nipple 4. The said passages 5 are disposed exteriorly of the nipple 3, and a valve member 6 is slidably mounted upon the nipple 3 and the same is adapted to close over the upper ends of the passageways 5. The fitting 2 is further provided with longitudinally disposed openings 7, which are located cxteriorly of the nipple 4:. A valve member 8 is slidably mounted upon the nipple 1 and is adapted to close against the lower ends of the openings 7 A nut 9 is screwed upon the lower end of the nipple 4 and is adapted to retain the valve members in position upon the nipple. The fitting 2 is provided at its outer side with a soft rub ber sleeve 10, adapted to fit snugly against the interior surface of the well casing 1. A cage 11 is mounted upon the upper end of the fitting 2 and is provided with a number of openings 12. A cylinder 13 is connected at its upper end with the nipple 4, and carries at its lower end a ball valve 14. A valve controlled plunger 15 is located in the cylinder 13, and is connected with the stem 16, which extends through the center of the fitting 2, through the nipple 3, and through the center of the cage 11. A perforated liner 17 is located in the casing 1, at the lower portion of the well.

When the pump is lowered into the well, the valve 8 rests upon the upper end of the liner 17, and closes the lower end of the openings 7 and which remains closed, duringthe operation of the pump. In operation, the stem 16 and plunger 15 are reciprocated in the cylinder 13 by gas, oil, and other fluid drawn into the c linder 13 and forced upwardly through tile passageway 5 and under the valve member 6 of the cage 11.

From the cage 11, the fluid asses through the openings 12 and enters t e upper portion of the casing and flows out at the top of the well. In order to remove the pump from the well, the fitting 2 and valve 8 are lifted oil of the upper end of the liner, and thus the valve may pull away from the lower ends of the openings 7, and permit the pumpto be lifted out of the Well, without lifting the liquid in the well above the pump. In an oil well which does not have gas pressure enough to cause the oil to flow, the hereinbefore described device may be used, and at less expense than by swabbing the well, in order to remove the contents from the upper portion thereof before lifting the pum out of the well. There are wells, in whic the production is too large to pump with the regular pumping equipment, and such wells do not have sufiicient gas pressure to cause the oil to flow, and for that reason the producer is forced to swab. When thepresent device is used, it will agitate the contents of the well and keep the contents flowing, and when it is desired to remove the pump from the well, in order to make repairs, 1t only takes a short time to pull the pump out of the well.

Having thus described the invention, what is claimed is:

1. A working barrel structure comprising a fitting provided at its opposite ends cylinder, said fitting being provided with passageways which communicate with the upper end of the cylinder, the valve member slidably mounted upon th smaller nipple and adapted to close the upper ends of said passageways, the said fitting being provided with other passageways located beyond the first mentioned. passageways, and a valve member located upon the larger nipple and adapted to be disposed in the lower end of tie second mentioned passageways.

2. A working barrel structure comprisin a fitting having nipples at its opposite ends, the said fitting being provided with an inner set of passageways communicating at one end with the interior of one nip- 1e, and having their other ends located yond the exterior side of the other nipple, a valve member slidably mounted upon the last mentioned nipple and adapted to close against the ugper end of the said assa eways, the 'sai fitting being provied with other passageways located beyond the first mentioned passageways, a Valve member slidably mounted upon the lower nipple and adapted to close against the lower end of the second mentioned passageways, a cage mounted upon the fitting, and a packing sleeve located. upon the exterior surface of the fitting and below the cage.

In testimony whereof I aifix my signature.

, CHARLES P. HOWE.
