Y UNITED STATES JEFFERSON C. CARNER, OF MARIETTA, OHIO.

BY-PASS.

Application filed August 11, 1923. Serial No. 656,981.

To all whom t may concern:

Be it known that I, JEFFERSON C. CAR- NER, a citizen ofthe United States, residing at Marietta, in the county of Washington and State of Ohio, have invented a new and useful By-Pass, of which the following is a specification.

This invention relates to a by-pass barrel, one of its obj ects being to provide a structure 4 of this character which, when .the well tubing is pulledbefore the fluid has been returned to the well, will allow the fluid to flow downwardly to the producing strata, the agitation of fluid thus set up serving to clean the structure from paraflin deposits, thereby causing an increase in the flow of the fluid.

A further object is to Iprovide a by-pass barrel which, by allowing the fluid to flow downwardly during the pulling of the tubing, saves the waste that would otherwise occur when the tubing is pulled, it being estimated tlrat without such a means for permitting down flow of the fluid, approximately six barrels of oil would be wasted on the derrick floor every time fteen hundred feet y of two inch tubing was pulled.

A further object is to provide a structure of this character which can be attached to the bottom of the regular working barrel of lany pumping oil well without interfering with the operation of the same.

With the foregoing and other objects 1n view which will appear as the description proceeds, the inventionA resides in the combi-` nat-ion and arrangement of parts and in the details of construction hereinafter described, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed withoutl departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In saiddrawings- Figure 1 is a section through a portion of the regular working barrel of a Well and the working valve, a portion of the trip plunger being shown. y

Fig. 2 is a section through that portion of the structure below the part illustrated in fFig. 1 rand illustrating the lower portion of the trip lunger, the standing valve, the agitating tu e, and other parts associated therewith, the valves in both Figs. 1 and 2 being -shifted to permit down How of Huid.

Fig. 3 is a section on line 3-3, Fig. 1.

F 1g. 4 is a view of the structure shown in Fig. 1 and showing the valves in their normal or cut off positions.

Fig. 5 is a sectional view of'that portion of the structure located below the portion illustrated in Fig. 4.

Referring to the figures by characters of reference 1 designates the regular working barrel of a well. the lower end of which is coupled, by a sleeve 2, to the upper end of the casing 4 of the working valve. A tube 5 is supported within the casing 4 and is provided, near the upper and lower ends of said casing, with ports 6 and 7 respective* ly opening into the casing 4. The usual working valve 8 is mounted for reciprocation within the tube 5 and has a tubular core 9 on which are mounted the usual conical washers 10 and cups' 11 of leather or the like. A cage 12 is formed at the upper portion of the working valve and houses a ball valve 13. Extending .upwardly from the end of the working valve is a threaded stud 14 adapted to be engaged by the rod 15. Longitudinal grooves 16 are' formedin the outer surface of the cage and open through the top thereof.

A trip plunger 17 is secured to and extends downwardly from the working barrel and is adapted to move upwardly and downwardly within said barrel and relative to the tube .5.

The lower portion ofthe casing4`is coupled by a sleeve 18 to the upper portion of y a casing 19A. and secured in the upper end of this casing 19 and extending downwardly into the lower .end portion thereof is a tube 2O having upper and' lower ports 21 and 22 respectively opening-- into the casing 19.Y A screw plug 23 is locatedclose to and above the port 22 and constitutes an abutment for one end of a coiled spring 24 the other end vof which bears against a standing valve 25 mounted for reciprocation in the- 424 and plug 23 and projects below the tube 20, the lower end of this tube 27 being open as shown. A ball valve 28 is loosely mount- `ed in the cage and is normally seated on vthe This normal position of the cage against its seat has been illustrated in Fig. 4. The standing valve includes the usual arrangement of conical Washers 32 and cupped washers 33 designed to work in tube 20.

The lower end of the casing 19 is coupled by a sleeve 34 to a perforated tube 35 that hangs downwardlv within the well and constitutes an agitating tube.

Under normal conditions the spring 24 holds the tapered upper end of theI cage 26 against the vseat 31. The well can be pumped in the usual manner and it is obvious that the improvements constituting thel present invention will not interfere with the working thereof. When it is desired' to draw the tubing without wasting the oil contained therein, the rod 15 is moved downwardly so as to bring the working valve to the position shown in Fig. 1. Thus the ports 6 will be placed in communication with the grooves 16 and all fluid contained within the barrel will be free to flow downwardly through port 6 and into casing 4 and thence downwardly through the ports 7. When the working valve islowered, as described. the trip plunger 17 will come against and force downwardly the standing valve so as to bring the grooves 2S) into communication with the ports 21. Thus the oil passing downwardly from the ports 7 will be free to flow into the casing 19 and thence downwardly through ports 22 into the tube 35. It will here flow outwardly through the apertures in tube 35 injets that thoroughly agitate the contents of the producing strata. and dislodge accumulations of parati-in or the like. Consequently when the well is again used for the purpose of elevating oil or the like, it will be-found that the fluid will flow more freely than would otherwise be possible. Thus the invention constitutes a means not only for effecting a saving of oil contained within the working barrels and tubing, but also a means for removing paraffin adhesions from the walls of the producing strata.

During the ordinary working of the apparatus the cups 11 and- 33 of the valve are protected by the tubes 5 and 207 from the rush of fluid assing through the apparatus.

For t e purpose of insuring proper ejection of the jets of fluid through the apertured tube 35, a plug 36 is seated in the lower end of said tube 35 where the tube is coupled, by a sleeve 37, to a lower tube section 38.

\ i ,meezit lVhat is claimed is 1. The combination with a working barrel, a casing coupled thereto, a lower casing, an apertured agitating tube closed at its lower end, and means for coupling theupper end of the agitating tube to the lower casing, of tubes supported longitudinally within the casing, a working valve mounted for reciprocation within the tube in the upper cas-4 ing, there being upper-'and lower portswithn in said tube, a rod connected to the working valve, said valve when in raised position constituting means for closing communication between the barrel and the upper ports lin the tube, a yieldingly supported standing valve .in the tube in the lower casing, said tube having upper and lower ports, the upper ports beingv normally closed by the standing valve, and means operated by the downward movement of the working valve for engaging and lowering the vstanding vvalve to open. communication through the ports for gravitation through the casing to the agitating tube of fluid supported within the barrel.
