Description
TUBING DRAIN Filed Dec. 27, 1927 gwue'ntoci atented Apr. 29, 1930 This invention relates to new and useful im rovements in a tubing drain.
"* 81cc object of the invention is to provide a device of the character described specially adapted for use in pumps, used for pumping r fluid from a well and wherebythe fluid 1n the pump may be rmitted to drain back into the well when t e tubing is pulled out of the bore. In pumping wells, particularly oil wells, it often becomes necessary to pull the pump tubing for repairs and replacements, and as the tubing is pulled it is broken up on the derrick floor. When pumps at present commonly used, are employed, the
16 tubing cannotbe drained and as it 1s broken up the oil or other fluid therein is spilled out on the derrick floor and wasted. It 18 the prime object of this invention to prov de means for draining the fluid in the tubing 20 back into the bore, as the tubing is pulled,
conventional pump it may as well be applied to any character oftubin in a well bore.
Another object of the invention is to provide a device of the character described that may be cheaply and easily constructed and easily operated.
With the above and other obgects in view this invention has particular re ation to certain novel features of construction operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a vertical sectional view of the upper end of a pump showing the improved means for drainin the tubing, and
Figure 2 shows a vertica sectional view of the lower end of the pump.
drawings, wherein like numerals of reference designate similar parts in each of the figures the numeral 1 designates a ump working barrel in the lower end of whic the standing valve, 2, of conventional construction, is located. A pi e, as 3, may be connected to the lower end of the working barrel if desired. The numeral 4 desi ates the ump tubing which extends up to t e ground surface. Attached to the lower end of the and while the drain is shown as applied to a Referring now more particularly to the- UNITED STATES PATENT OFFICE mm H. ALLEN AND MORRIS E. STANDIEEB, Oil GOOSE CREEK, TEXAS y -TUBING DRAIN application filed December 27, 1827. Serial 1T0. 242,944.
tubin is the reducing nipple 5 to the lower end 0? which a coupling 6 is connected. The lower part of this coupling is thickened in- Wfil'dlj'illdfOIIIlGd with the internal annular downwardly converging seat 7 and beneath said seat is provided with the drain openings 8. Beneath said 0 enings the inwardly thickened portion of tli ternally threaded and screwed on to the elongated tubular nipple 9 which is attached to the upper end of the working barrel.
The-upper end of the nipple 9 has an external annular'downwardly converging seat, 10, arranged opposite the seat 7, and also has the drain ports 11 therethrough, above the seat 10. The upper end of the nipple 9 is spaced from the coupling 6 to provide a fluid passageway 12 which is closed when the seats 7 and 10 are seated against each other and which, at other times, is open.
In the working barrel there is the conventional traveling valve 13, operable through the usual sucker rod 14.-
During the operation of the pump the nipple 9 is screw ed down through the coue coupling 7 is inpling 6 until the seat 10 seats securely against the seat 7 so as to effectively close the passa way 12.
en it is desired to pull the pump tubing the traveling valve 13 and sucker rod 14 are withdrawn and said tubing may then be turned to screw the coupling 6 downwardly on the nipple 9 to carry the seat 7 away from the seat 20 to open said passageway 12. During this operation the nipple 9 should be held against turning by any type of casing lock which may be carried by the pipe 3 and which isconstructed to engage the casing to prevent the turning of said nipple. This will permit the fluid in the tubing to drain out as the tubing is elevated and broken up in removing the same from'the well bore. Before again lowering the pump into the well the'nipple should again be screwed down through cou pling 6 until the seats 10 and 7 abut and form a fluid tight joint. I
The construction for draining the tubing may be located at any desired point along the tubing, above the standing valve.
It is obvious that mechanical changes may be made in the construction, and equivalents substituted for the parts shown and we hereby reserve the right to make such mechanical changes substitutions and adaptations as may be comprehended within the scope of the appended claims.
What we claim is l. A device of the character described having a tubing provided with a drain passageway and including relatively rotatable parts having means efiective to open and close said assageway, said means being characterized y'the provision of oppositely disposed coa'cting se s and operative connections wherev v by one of sa'ishseats may be positively moved Y away from the other seat and positivel I I moved into and main seatedrelationwit said other seat. a f v,
- 2. In a device of the character described a tubing having an internalannular seat and a drain outlet, a tubular member having a threaded connection with said tubing and having an external annular seat opposing said internal seat also. having a drain 0pen-' ing said seat's beihg movable toward and froln each other bythe relative rotation of said tubing and member, said threaded connection being effective to positively hold said seats in seated relation to close said passageway.
3; A device of the character described including a tube having a drain passageway, tubular parts incorporated into said tube and connected bythreads, the-walls of said passageway having opposing seats which are movable, by said threads, into contacting relation ,to close the passageway when said parts are relatively rotated in one direction,
' said seats being movable by said threads, into spaced relation to open the passageway when 40 said'parts are relatively rotated in the other direction. In testimony whereof we have signed our names to thisspecification. Y 1
