DUMP AND SEAL TUBING VALVE Filed Aug. 30, 1929 Patented Dec. 9, 1930' UNITED STATES PATENT- OFFICE Bowman F. minimum, or roar won'rn, assrouoa'ro GULF i aonuc-rion courxmr, or nous'ron, Tmaa conromr on or Texas Y I I DUMP AND SEAL-TUBING vALv'av Application filed August 30, 1929. Serial No. $89,512.
I This invention relates'to devices for automatically draining long strings of tubing of fluids, entrained solids or a mixturethereof. The tool or device mayconv'eniently'be designated as a combination dump and seal tubing valve. I v p 7 i v Oneobject of the present invention is to provide a tool or device of this character by V theuse of which practically all waste of oil is eliminated when the well tubing is removed. from the well. A furtherobject contemplated is to provide a device that will improve the operation of a pumping oil well. Heretofore there has been a considerable loss of time in operation due to the accumulation of sand or salt or other foreign substances in the working parts of the pumping 'mechanism, but, by use of the present invention. this time element or loss of time is greatly reduced. A still further object'is to construct the resent device in such fashion thatitmay e'produced at a relatively 'low cost by reason of the simplicity of its construction. This simplicity of construction also reduces the likelihood of the apparatus getting out of working order.
With these and other objects in view, the invention consists'of certain details of construction and combinations and arrangements of parts, all as will hereinafter be more fully described and the novel features thereof particularly pointed out in the appended claims.
In the accompanying drawings,
Fi re 1 is a sectional view taken longitudinally of a well casing and illustrating the lower end portion of the pump working barrel which carries the device constituting the present invention,
Fig. 2 is a transverse sectional view on the line 22 of Fig. 1,
Fig. 3 is a similar view on line 3-3 of Fi 1. V
is is well understood in the art the pump working barrel 10, the lower portion only of which is illustrated in the present instance, extends down through the well casing 11. Attached to the lower end of barrel 10 is what will be termed a coupling or barrel seat means 12, said coupling having a tapered pIrojecting portion o center bore 13' which constitutes a valve'seat 14 for a valve member 15 whose cross-section corresponds to the bore of coupling12. For convenience this valve member, may be termed a mandrel, and extending through it is a center bore 16, into the upper end of which there is threaded a standing valve nipple 17 on which is secured the usual standing valve 18 for controlling the passage of fluids through said center bore 16. Standing valve-18 may be of any desired type, in the present' instance' being simply illustrated as a ball 18 within a cage 19. A portion of the mandrel or valve'15 proects without or below coupling 12, and to the 'pro'ecting portion? of saidvalve there is attache what will be termed a lower coupllng 20,; bored to receive'the'end of said valve 15 as well as amud anchor 21; In the.
juxtaposed end surfaces of couplings 12 and 20 are recesses 22 and seated-in said recesses is a coil sprin 23"surroundi'ng the valve member 15. ormally, the action of spring 23 yielding- 1y urges couplings 12 and 20 awayfrom one another for the purpose of maintaining the tapered portion of valve'1'5 'againstiits seat 14 in coupling 12. n V
*When in use the device is assembled between the working barrel and the mud anchor, as shown, and, when the tubingjis run the stringis allowed to swing afew inches of! thebottom of the well; Under which circumstances the valve 15 will be'seated as wwell'by gravity as by the influence of spring 23.: As the fluid head bu'ilds-up in the tubing, the pressure exerted on the top of the mandrel becomes gradually more efi'ective in seating said valve15, so that a perfectly tightjoint is formed. However, if for any reason it should be desired to flush the tubing, said tubing is lowered until the mud j anchor comes into contact withfthe] bottom of the well and by further slightly. lowering the tubing the coupling 2mm move relatively, to coupling20 so as to unseat valve '15 whereupon foreign substances may. drain or escape through the clearance that is then provided between the saidvalve and its seat 14. After thus flushing the tubing, the/latter is raised until the mud anchor is lifted free of the bottom of the well whereupon the tension of spring 23 together With the weight of the anchor will return the mandrel or valve 15 to its seat 14.
WVhat I claim is:
1. In a device of the character described, the combination of a working barrel, a valve seat carried by said barrel, a coupling spaced below said barrel, said coupling and barrel bein movable toward and from each other and a valve attached to said coupling and operatively associated with said valve seat, foreign material within said barrel being free to escape at a point between the coupling and. valve seat member when said valve is unseated by movement of theibarrel and coupling toward each other.
2.

3. In a device of the character described, the combination of a working barrel, a coupling attached to said barrel and provided with a valve seat, a valve member having a central bore and projecting through said coupling beyond the end of the barrel, said valve member being movable longitudinally upwardly of the barrel away from its seat, and means for yieldingly urging said valve against its seat. a
4. In a device of the character described, the combination of a working barrel, a coupling attached thereto and provided with a tapered central bore forming a valve seat, and a tapered valve member adapted to engage said seat and project beyond the lower end of said coupling, said valve member being movable longitudinally.upwardly of the barrel to displace it from its seat. 7 5. In a device ofthe character described, the combination of a working barrel, a cou pling attached thereto and provided with a central bore forming a valve'seat, a tapered valve member adapted to engage said seat,
couplings being movable toward each other to unseat said valve.
7. In a device of the character described, the combination of a working valve, a coupling attached thereto and provided with a tapered central bore constituting a valve seat, a tapered valve adapted to engage said seat and projecting without said coupling, and a second coupling attached to the projecting portion of said tapered valve, said couplings being movable toward each other I to unseat said valve and a spring interposed between said twocouplings yieldingly urging the same away from each other to seat said valve.
8.. In a device of the character described, the combination of a working valve, a; coupling attached thereto and provided with a tapered central bore constituting a valve seat, a tapered valve adapted to engage said seat and projecting without said coupling," and a second coupling attached to the projecting portion of said tapered valve and movable toward said valve seat to unseat said valve, the opposed surfaces of said couplings pling attached thereto formed with a centra-l bore, a valve member normally closing said bore and projecting without said coupling, a second coupling attached to the projecting portion of said valve member, said valve member being movable longitudinally upwardly of the barrel to open said central bore, and said'valve member having a passage therein through which fluid may pass from the coupling attached thereto to said barrel, and a valve for said last mentioned passage.
