An object of the invention is to provide a pump of the character described specially designed for I designates a pipe set in a well bore. _ _ Incorporated into this pipe there is-a special use in deep wells such as oil wells. . coupling 2 having the inside, downwardly taper Another object of the invention is to provide the novel combination of a sucker rod, plunger, and working barrel that may be lowered into, or ing seat 3. withdrawn from, a well as aunit. which has the vertical inlet slits, or openings, 5, ' A further object of the invention is to provide, 10 in a pump, a novel type of valve mechanism for controlling the discharge of the pumped liquid from the working barrel. A still ‘further object is to provide, in combi nation, a novel type of ‘working barrel arranged -- to be suspended from a seat in the well pipe, and having controlling means at the upper end there of arranged to cooperate with the pump plunger, > . W The numeral 4 designates the tubular working barrel of the pump whose lower end is open and spaced above said lower end. - . A tubular plunger 6 works through the working 1 barrel and is spaced inwardly therefrom and has the upwardly opening cup ring assembly ‘I there on forming a close ?t with the working barrel. The upper end of the barrel 4 is attached to a tubular hanger 8 whose upper end is?ared and 15 seats on the seat 3 to support the working bar rel in suspended position from said seat. The ' said plunger being attached to, and operable by, the sucker rod, "and said rod, plunger, and work upper end of the ‘hanger is formed into a cage 8a. ing barrelbeingwithdrawable as a unit from the well. moulded into the cage. Its outer side is tapered '20 downwardly to conform to the shape of and to ?t A sleeve-like packing element 9 has its lower end ' A still further object of the invention is to ‘ closely against the seat‘ 3. This packing element provide, in a well pump apparatus, novel means 8 is formed of resilient material and its upper end for supporting the pump in well pipe. said sup~ is reduced in outside diameter and extended-up porting means being either formed as a part of wardly ?tting closely about the plunger 6. In the 25 said pipe, or being separate from the‘ pipe, and form shown in Figs. 1, 4, and 6, the upper end of~ , said extension is upwardly ?ared, as at l0, and suitably anchored therein. with the above and other objects in view, the invention has particular relation to certain novel features of construction, operation, and arrange ment of parts, an example of which is given in this speci?cation and illustrated in "the accom panying drawings, wherein: Fig. 1 shows a side view oi.‘ the pump, partly in section. ' Fig. 2 shows an enlarged, fragmentary vertical sectional view, showing a modi?ed form of the valve mechanism for controlling the advance of ?uid upwardly. ~ ' Fig. 3 shows an enlarged cross-sectional view taken on the line 3-3 of Fig. 2.1 Fig. 4 shows a side elevation, partly in section, of the upper portion of a slightly modi?ed form of the type of pump shown in Fig. 1. Fig. 5 shows a vertical sectional view of the lower portion thereof.‘ ’ Fig. 6 shows a side view, partly in section, of _, the upper end portion of the type of pump ‘shown in Fig. 1, but showing a modified form of pump support in the well pipe, and ‘ . Fig. 7 shows a side elevation, partly in section, of the lower portion thereof. I Referring now more particularly to the draw 65 ings wherein like numerals of reference designate varound. said reduced portion .is providedwi'th an external annular groove ll. . ‘ ‘ The lower end of the plunger 6 is extended be- 30 neath the working barrel and has an external an _ nular stop' 12 thereon. The plunger may be re- , ciprocated by a suitable power ‘at the ground sur face through the instrumentality of the usual sucker rod l3 whose lower end is connected to a 35 bell-shaped nipple it which, in turn, is secured to the upper end of 'said plunger. _ . In the form shown in Fig; 2, the upper end of the working barrel is attached to the lower end of the hanger l5 whose upper end is upwardly ?ared to conform to the shape of and to ?t the seat 3. Aboveand resting on the hanger i5 is the cage l6, having the external radial lugs ll. The ?ared portion of the hanger 15 has the deep’ sockets l 8 at its under side, and rods 19 have their -upper ends anchored to the lugs l1, and extend downwardly through bearings in the hanger, and their lower ends have enlarged heads 20 in said sockets. The upper end of the hanger l5 has an annular groove 21 in which a packing washer '22 is located. A sleeve-like packing element 23 surrounds the plunger 6 and its lower endis moulded into the cage l6,'and seated in an annular groove in the lower end of the packing element 23, there is a 40 45 50 55 2 2,130,598 packing ring 24 which registers with the groove 2|. tive to the liner 21, but prevents their complete ‘ separation. > The apparatus, as shown in Figs. 1 and 2, may be assembled and let down into the well by means of the sucker rod l3 until the hanger supporting tne working barrel lands on the seat 3. The - sucker rod may then be lowered until the margin l4 seats in the groove H of the shown in Fig. 1 or‘on the lugs" of the 10 shown in Fig. 2, and the hanger thus forced lower, form form ?rm- . ' Fastened to the upper end of the liner 29 are the outwardly movable pipe-engaging slips 34 whose inner sides taper upwardly and outwardly and whose, outer'sides have the pipe-engaging teeth 35. Formed on the pipe la. is the expander 36 which tapers downwardly and which is shaped to fit in between and expand the slips 34. Above said expander there is an expansible packer 31 10 ly in place in the seat 3, and for that purpose, if ' around the pipe la and whose lower end is suit necessary, the sucker rod may be successively ably anchoredthereto and attached to the upper elevated and dropped to drive the hanger ?rmly end of said packer, there is a suitable setting nip in its seat. The pump is then ready to operate. ple 38 whose lower end has the expansible grip Upon downward movement of the plunger 6, a ping dogs 39 arranged to engage the external 15 vacuum will be created in the working barrel teeth 40 on the pipe la. The screen, liner and abovethe cup rings 1 until said cup rings clear pipe la with the packer and packer-expanding the openings 5,» and thereupon the surrounding ' means thereon and heretofore described may be liquid to be pumped will ?ow in “through the openings 5, the plunger moving on downwardly to assembled and let down into the well bore by a suitable ‘setting string provided for the purpose carry the cup rings 1 beneath the openings. ~ In ‘ and when the set shoe 3| lands on the bottom, the . 20 this'connection, it may be stated that‘ the pump expander 36 will move on downwardly, expand should be lowered to a sufficient ‘depth to carry ing the slips 34, into engagement with the casing the openings 5_ beneath the level of the liquid to 28. This wil1 prevent further downward move be pumped. Upon upstroke of the plunger, the ment of the pipe la, but the weight of the setting cup rings 1 will'move up and close the‘ openings string will cause thenipple 38 to move on down 25 5 and trap the liquid above in the working valve, Iwardly to expand 'the'packer 31 to- form a ?uid and this liquid will be forced on up and the yield tight joint between the pipe Ia and the outer cas able packing 9 will expand outwardly to permit ing 28. Upon downward movement of the set the ?uid to pass between it and the plunger, and ting- nipple 39, the gripping dogs 39 will rachet .30 said liquid will be trapped-above the packing ele over the teeth 40 and will thereafter hold the ment 9. - In the form shown in Fig. 2, upon up ward movement of the plunger, the packing ele ment 23 will move upwardly until the heads 20 engage the upper ends of the sockets l8, and the ?uid will pass up and out between-the hanger l5\ and the lower en of the packing element 23, the excess ?uid passi, g up between the packing ele ment 23 and the plunger, said packing element ‘ packer expanded. - ' ,The pump may be then assembled and let down ' into the well and the hanger seated in the‘seat 3, as shown in Fig. 6, and driven therein by the 35 nipple l4, as hereinabove explained, and pumping operations proceeded with in the manner above set forth in connection with the description of Fig. 1. ‘ expanding to permit this.
