' MEANS PREVENTING THE ACCUMULATION oreAs WITHIN OIL-WELLS.

Specifica'tion of Letters Patent.

Patented May 18, 1915.

Application filed march 10, 1914. Serial No. 823,819..

To all whom it may concern Be it .known that I, ALEXANDER- AMns,

. citizen of the United States, residing at Alluwe, in the county of Nowata and State of Oklahoma, have invented certain new and useful Improvements in Means Preventing the Accumulation of Gas WVi'thin Oil-VVells, of which the following is a specification.

This invention relates to meanswhereby the gas of an oil well may be allowed to escape. It is a well known fact that an oil well, after having been pumped of its original contents, will, in time, again refill. Valves, in oil well structures, are old, one valve being ordinarily arranged within one of the lowermost of the oil well barrels or sections, said valves automatically closing the well upon the cessation of a pumping operation. Gas, during a refilling of the well accumulates within the perforated pipe or lowermost section of the said well structure, and, as at present, the inflow of oil within said section is checked and finally stopped by the confined gas, the primary object, of the present invention is to provide an eflicient structure whereby an outlet for the said confined gas is effected, such gas escape permitting the oil to rise unhindered and unobstructed within the well. The above and additional objects are accom plished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a longitudinal sectional view of a portion of an oil well structure illustrating the arrangement of the improved oil well section comprising the present invention; Fig. 2 is a top plan view of the said section; and Fig. 3 is a section on the line 33 of Fig. 1.

Referring now to the drawings by numerals, 1 designates an oil well section within which the lowermost valve (not shown) operates, said section being exteriorly threaded as indicated at 2 to provide for the arrangement thereover of the valve sec tion 3, comprising the present invention.

The lowermost oil well section 4 is threaded as indicated at 5 intothe opposite end of the said section?) from that receiving the se'otion l, said lowermost section 4; being perforated to provide for the inflow of accumulating oil. 7 the section 3 and integral therewith is a bridge wall 6 having a concentric vertical bore 7 formed therein, said bore being threaded as at 8 toreceive a pipe section 9 extending concentrically and in a vertical plane into the interior of the section 1 to. a point below and adjacent the valve (not shown). Said bore 7 is in communication with a second bore 10 extending at right angles thereto, the latter bore terminating or leading into a second vertical bore 11 formed in the wall of the said section 3, the said wall extending upwardly to a point above the free end of the pipe section 9 whereby to position the mouth of the bore 11 in a plane above the top of the said section 9.

As the oil flows into the well through the perforations of the section 4, the air and gas within the well is forced upwardly and against the valve (not shown). Should the pressure be low, the upward pressure upon said valve is insuficient to unseat the same, in which event, further inflow of oil is checked. It is to provide for the escape of the confined gas within the oil well that the outlet formed by the pipe section 9, bore 7 bore 10 and bore 11 is provided. By extending the section 9 upwardly into the section 1 having the valve operating therein, it is apparent that as the oil rises within the well, the gas is forced out into the oil well proper, thereby permitting unobstructed and unhindered rise of the oil within the well. By bridging the section 3 as indicated in Figs. 1 and 3, the rise of the oil within the well is unobstructed, a passageway being formed upon each side of the bridge wall 6 sufliciently large to accommodate the rising oil.

From the above, taken in connection with the accompanying drawings it will be noted that by disposing the mouth of the bore 11 upon a plane higher than the free end of the section 9, the gas is forced out into the well proper until the oil within the well has risen to a point whereby the mouth of the pipe section 9 is filled; that the said outlet 11, may be, if desired, extended upwardly parallel with the well section whereby to Intermediate, the ends of enlarging the section 3 annularly a s indicated at "12, .a meansiis provided whereby adjustment of the section 1 Within the said section 3 is limited. 1 I t In reduction to practice, I have found that the form of my invention,illustrated-inthe drawings and referred to in the above description, as the preferred embodiment, is the most eflioient and practical; yet realizing that the conditions concurrent with the adoption vof my device Willinecessarily vary,

I desire to emphasize the'fact' th'at various I 1, In means preventing thefaccumulation minor changes in details of construction,

proportionand arrangement of parts may be resorted to, when required,With'outsacrifici'ng any o f jthe advantagesof my inventi'on,as defined in the appended claims.

Having thus fully described my invention,what I claim'as new and desire tosecure by Letters Patent, is

for thewpurpose specified.
