OIL-PUMP.
sPEoIFIcATIoNferming part-ef Lettere Patent ive-687,067, dated November 1e, 1901.
To all whom it may concern/.-
Be it known that LOLARK F. RIGBY, a citizen of the United States, residing atNew Martinsville, in the county of Wetzel and State of West Virginia, have'invented certain new and useful Improvements in Oil-Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to deep well oilpumps; and the primary object thereofis toV provide a simple and eective pump adapted to be operated by a wire or other cable in place of they sucker-'rods now usually'employed for connecting the pump and walking-beam. 1
A further object is to provide a pump which includes a stufng-box, plunger, and other necessary adjuncts, which may be lowered to position inthe well-tube by means of the operating-cable,or removed therefrom by means of the pump-actuating cable, at the pleasure of the operator.
A further object is to so construct the pump mechanism and well-tube that by partially withdrawing the Vformer the column of oil in the tube will be discharged laterally through the base thereof for the purpose of washing the wall of the well.
A 'further object'isto provide improved means for packing and for lubricating the plunger. v
'Theinvention consists in the novel features of construction'and combination and arrangement of parts, hereinafterfully described and claimed, and illustrated by the accompanying drawings, Wherein Figure 1 is a vertical sectional view of a pump and well-tube constructed in accordance with my improvements. Fig. 2 `is a similar View of the lower portion of the same.` Fig..3 is a similar view of the upperportion of the pump. p.
Referring to the drawings, 2 represents the well-tube, and uniting with y.the lower end thereof is the elongated chamber 3. `Depending from the lower end of this chamber is tube 4, provided with foot-valve 5. Chamber 3 forms a bottom continuation of the welltube, and formed therein is the downwardlytapering seat 6, here shown immediately below the laterally-extending outlet-openings ser'iel No. 54,787. on meae1.
7. i' Formed complementary with seat 6 is the tapered supporting-head 8l of the stuffing-box through which plunger 9 reciprocates. Depending from head 8 is anchor-tube 10, containingstanding valve 11, and secured to the extremity of plunger 9 beneath head 8 is the V enlarged valve-cage 12, provided with ballvalve 13. The stuffing-box is formed with a stem portion 14 where it unites with head 8, confining on the upper end of the latter the leather cup 15, which is expanded by the column lof oil in space 16 between tube 2 and the stuffing-box and caused to tightly t chamber 3 above apertures 7 and prevent the oil from discharging therethrough.
. The operating-cable is attached to the plunthe cup and flow out through apertures 7, i
from which it discharges onto the faces or Walls of the Well for the purpose of cleansing themf For removing the entire pump from the well the said upward movement is simply continued, all portions of -the pump being of such diameter as to pass upward freely through tube 2, including free passage of an- Y Chor-tube 10 through seat 6. When the pump vis raised, asabove described, for flooding the well through apertures 7, tube 4 and valve 5 prevent the oil from discharging through the lower end of the well-tube. sired to utilize the flooding feature, said tube 4 audits valve may be omitted. e The upper and enlarged portion of the stuifing-box consists of lower section 17 yand up- If itis not deper section 18, threaded-together at 19. `The.
contracted lower end of box-section 17 forms an abutment 20, and,A above the same and arranged successively Aat separated points are the abutments-21, 22, and`23. Abutment v21-is confined on Vthe upper end of box-section 17, abutment 22 is spaced therefrom by sleeve 24, and abutment 23 is spaced from abutment 22 by sleeve 25. Embracing plun- IOO ger 9 are two series 26 and 27 of split metallic packing-rings, which are spaced apart by elongated sleeve 28, flanged at 'its lower end i justed by lock-nut 37.
at 29 and provided with side perforations 30. Confined between lange 29 and abutment 2l is soft packing 3l, which surrounds split rings 26, while confined between the lowermost and flanged ring 26' and base-abutment 2O is spiral spring 32. Confined between abutment 22 and lowermost and iianged ring 27 of ring series 27 is spiral spring 33, and inclosed between abutment 23 and wide wing 34:, bearing on the upper end of ring series 27, is soft packing 35, which surrounds the last-named rings. Threaded into the Lipper end of boxsection 18 is bushing 36, which bears on wide ring 34 and by means of which both the metallic and soft packings are adj usted as the conditions ot' working may require. Gland or bushing 36 is held xed after being ad- Longitudinal movement of the column of metallic packing is resisted intermediate its ends by spring 33 and at its lower end by spring 32, so that the several rings are held tightly together or in close relation. Abutments 2l and 23 prevent the soft packing 3l and 35 from moving downward. Hence said packings are compressed by the inward or downward movement of the metallic packing, and this compression contracts rings 26 and 27 on plunger 9, and by this means the packing may be made either loose or tight, as may be required.
Space 3S between sleeve 28 and the inner wall of the stuffing-box is iilled with a suitable lubricant, such as soap, graphite, or a suitable oil, which reaches the surface of the vplunger through sleeve-aperture 30, whereby the plunger is maintained in a thoroughlylubricated condition and caused to reciprocate through the metallic packing-rings with comparatively little resistance and this without impairing the eiciency of said packing. Plunger 9 is apertured at its upper end at 39 to permit the oil being pumped to discharge therefrom, and coupled in usual manner to the upper end of the plunger by means of rope-socket 40 is the operating-cable 41.
With the weight of the column of oil in the tube bearing on cup 15 and with the plunger packed and lubricated as described the stuE- ing-box remains seated in tube-chamber 3 and there is no tendency on the part thereof to lift with the plunger. Also under these conditions the plunger works with sufiicient ease to drop of its own Weight for the downstroke, thus dispensing with the rigid suckerrod connection with the walking-beam heretofore necessary and making it entirely practicable to operate the pump with acable. In pumping a well several thousand feet deep the advantages of a cable over the cumbersome succession of sucker-rods will be apparent to those skilled in the art. The pump entire may be pulled out of the well-at any time for the purpose of repair, for adjustment, or forV replenishing the lubricant, and when being lowered in the well the pump takes its proper position, as in Fig. l, without the slightest hitch.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isi 1. A tube for deep wells having lateral outlet-openings, in combination with pumping mechanism removably positioned in the tube, the pumping mechanism consisting of anormally-iixed element which includes a stuffing-box, and a reciprocating element comprising a plunger which is operative in the stufdng-box, the fixed element of the pumping mechanism normally closing the tube and the lateral outlet-openings therein, substantially as shown and described.
2.
