'.To aJ/Z whom it myoncern:
Be itknown that I, FRANK H. TAYLOR, a citizen ofthe United States, residing atToronto, in'the c ountyof'Jefferson and State of Ohio, have invented certain new and useful Improvementsin Oil-Well Pumps', of which the following is a speciiication.- l
The object of my invention is to provide `an improved pump, particularly desi ned for oil or the like wells, and characterize by simplicity and durability of construction, andv ease and effectiveness'of operation.
For a full description ofthe 'invention and the merits thereof and also to acquire al knowledge ofthe details of construction of1 the vmeans for effecting the result, reference is to be had t'o the following description and accompanying drawings, in which:
Figure 1 is a longitudinal sectional view through ajpump embodying 4the invention,
"parts being brokenaway.. Y Fig. 2 is a similar view on an enlargedscale Yof the upper portion ofthe pump. '.Fig. 3 is a longitudinal- A sectional view of the pump, t he section being taken through the plunger.
Corresponding and like arts are referred to in the following description and indicated in all the views ofthe drawings by the same referencecharacters.
Referring to the drawings,the numeral `1 designates one section of the well tubing and 2 designates an v'adjacent lower sectionwhich is -connected to the section 1 by means of a coupling 3. The interior diameterv of the section 2 is preferably somewhat 4smaller than the interior diameter of the section 1 so as to produce an upwardly facing shoulder 4 at the `.juncture of the two sections, said shoulder being de signedprimarily to support the pump within the tubing. x
The pump comprises a liner barrel which. is constructed i'n two main sectiens, namely, an upper section 5a and a lower section 6'. The section 5ais intendedvto fit snugly within the upper section 1 .of the well tubing .and it is contracted or reduced at its lower end, as in dicated at 5b, the osettoform the 'contracted portion beingadapted vto rest upon the shoulder 4 of the well tubing so as tosuspend the `pump therein. As seen best in Fig. 3, the lower contracted end bof the'upper section 5a of the liner barrel, or pump body, is provided with an interior 'flange 5v3 producing av downwardly facingshoulder' 5d. The coupling sleeve 7 connects the upper secscrews around the upper section and inside of the lower section as shown, and its upper edge coacts with the shoulder 5d to clamp the inwardly turned edge of a cup 8 between them, the saidv cup snugly fitting against the 'wall of the lower section 2 of the well tubing.
AThe upper section '5F 'of the linerbarrel of the pump is secured at its up er end to a 'stufiing box 1 2 and ahollow p ungerrod 10 is .mounted to slide through the stuffing boX,
the upper end of said rod being secured to a cage 14 adapted for engagement by the sucker rod and containingthe ball valve 18. The interior of theupper section 5a of the liner barrel constitutes a packing chamber 5 the lower end of which isl constructed as shown best in Fig. 2'7by the formation of the` i Asaid section. .Y The inner wall ofrthis packing A chamber is constituted bythe rod v10 and in the lower end of this chamber packing rings 9 are'located. .Above vsaid rings thereis a follower 11 pressed upon by a spring which 'bears thereagainst and against the stuffing box 12. The lowersection 6 of the liner barrel'or pump body i connected at its upper end as above stated, to the lower end of the couplingsleeve 7 and extends downwardly y the: cup 8 which is locatedl preferably just underneath the coupling', while the. lower end ofV said space' is maintained closed by fme'a'ns of'a preferablyv leather cup 25 which 'is clamped between the inlet cap 24 screwed on the lower `end of a coupling neck 23,`said neck beingl-screwedzat its upper end into the loweren'd of ,thefsection 6 and sup orting in said lower end'a cage formed wit a valve seat upon which the pump valve or foot valve 22 is adapted to rest.
The hollow plunger rod 10, it will be seen, is spaced slightly from the section 6 and is only packed at its upper end by means of theA acking 9. To the lower end of s aid rod a ollow lunger 15 is secured, saidp'lunger snugly `tting the section uof the linerbarrel .and adapted to reci recate thereinland provided wlth a series o grooves 16 constituting fluid packing rings. To enable the oil to fill said spaces, the" lower-.end lof thevhollow rod 1.0 is provided with one or more ports 21.
The lowerendof the lungerlis rovided [tion 5a with )the lower section preferably 'v .wilth'a cage 18 in whic the. remova le valve IOC A pump/the oil is drawn into the lower section of the liner barrel betweenthe plungerxl' and the foot Valve 22. When the plunger descends this oilis forced upwardly past the valve 17 into and through the hollow plunger to the' hollow plunger rod 10, and thev oilwhich was before.in -theplunger rod is forcedfout through the upper plunger valve 1'3 andint'o thewell tubing. The valve 13 manifestly relieves the lower valve 17 of the pressureexerted bythe oilin the well tubing. and thereby insures the free operation of the.
ger 1-5 itself requires no acking except the fluid packingy constituted by the oil itself, which clearly promotes the durability and eiiiciency of thepump, and it is also to be noted that the solid particles such as sand which may be held in suspension by the. oil, are, prevented from accumulating in the space between the lower, section 6 vof the pump body or liner barrel and the well tubmg, owing to\ the .upper cup Sand the lower cup 25- l It is evident that thisarrangement will prevent such an accumulation of sand or the' like which would cause the pump barrelv to stick in the tubing and render it very difficult to remove the pum from the well.
Having thus descri ed the invention, what is claimed as new is: l. i f v A pump of the lcharacter described, adapt- It is to be particularly `noted that the plun.
ed to be sus ended in well tubing, the body of the pump eing constructed in upper vand lower sections, a hollow plunger rod mounted to reciprocate in said sections and provided with intake and outlet valves, a foot valve in the lower section of the pump body, the upper section of the pump body being contracted near its lower end and the o'll'set to produce the contracted portion constituting` I the means for suspending the pump within the tube, said upper section snugly vfitting vthe well tubing,I while the lower section is Aadapted to be spaced therefrom7 the upper section forming a packing chamber around the plunger rod, a packing in said chamber, a stuiling box secured to the upper end of the upper secti on, the packing chamber being reduced at its lower end by reason ofthe said contracted portion ofthe upper section, and the` said contracted portion being formed with a downwardly facing shoulder, and a threaded ortion beyond said shoulder, a coupling s eeve connecting the `lower section of the pump body with the said threaded extremity of said contracted portion of the uppersection, and a cup clamped between the l upper edge of said sleeve and thesaid shoulder, said cup being ada ted to engage the walls ofthe tubing an extend upwardly from the'said coupling with its free edge uppermost, and another cup secured to the lower. e'nd of the lower section of the um vbody and ada ted to engage the walls o f the ,f
tubing, as an for the purpose set forth,
In testimony whereof I'a'liix my signature of two witnesses.
