Application led April 1 5, 1922. Serial No. 552,935.

In the drawing Athe numeral 2 designates the ordinary perforated pipe. or anchor bellow the working-barrel 3 connected to' the pipe 2 by the coupling 4 of a suitable stand- 00 ing-valve 5'. The valve 5 has the openings -6v which arev controlled by the disc 7 which.` is adapt-ed to bemoved up and down on the stud-bolt 8, the head of whichfcontrols the upward movement of said disc.

` A` valve-seatf9 is-en aged bythe lower end vof theperforated plpe-section which is screwed in to the'recess 11 in said valveseat.

.This valve-seat -forms a closure for the 70 lower end of the `perforated pipe-section 10, and likewise forms an abutment by which the valve 7 may be pumped in case it hap. pens to stick.

The valve-seat 9 forms a seat for the 75 valve-'head I12 whichis adapted to slide on the perforated pipe-section 10, said head having the wings 13 moving in engagement' To all whom t may concern:

Be it known that I, VICTOR H. PALM, a citizen of the United States, and resident of Butler,- in the county bfButler and State 5 of Pennsylvania, have invented a new andv useful Improvement ini Pumps; Aand I do hereby declare the following to be a f ull, clear, and exact description thereof. i

My invention relates to pumps, and more 10 especially to deep-well pumps usedl for the pumping of oil or water at great depths.

\ It has been the common practice hereto-I fore in the pumping of fluids from deepwells, to employ a single-'acting pump due may be pulled `without pulling the tubing and workin -barreL .Thecapacity is there.` fore limite to the size of valves that will a double-acting pump so lthat the fluid is pumped on the up, as well as on the down stroke, and by putting the-second pump with said pipe-section 10, thekports 13 being above the first I increase the .capacity formed between said wings. -This forms the 80 nearly four-fold, while" at the same time I` space between the valve head 12 and the amy enabled to pull up the valves and other plpe, and the communication is thus formed internal parts without pulling the tubing for the full length ofthe plston, as the perfoand working-barrels. i rations in the pipe extend the full length If onlyone working vbarrel is employed, thereof.` 4 the top valve-head is used, and the capacity A like valve-heady 14 also surrounds the of the pump/will be increased nearly twopipe-section 10 and in sliding engagement fold over the single-acting pumps, so that therewith, and a spring l5a interposed bewhere a single-acting pump is to be worked tween the valve- heads 12 and 14 normally to its`limit to keep the water down, as is the holds said valves on their respective seats uo case in some oil-wells, my pump will do the .9 and 15, said valve head 14 havinga like I ing.

work by a slower motion, and therefore the wear and tear'will be reduced and less repair work required, and /if one valve gets outof order the other will still 4keep pump- Another object of'my invention is to provide a pump of the above character in which the parts are contained within'the workingbarrels, and there are no pipes exterior of the working-barrels by-passing the fluid from a lower Ito a higher level. L

In the accompanying drawing, Fig. 1 isl a vertical'section of the upper portion of my improved pump; Fig. 2 is a like view d y of the lowerportion; Fig. 3 is an enlarged -section on the line 3 3, Fig. 1; Fig. 4 is an enlarged section on the line 4 4, Fig.

1; Fig. 5 is an enlarged section on the linev 5 5, Fig. 1 and F ig. 6 is an enlarged detail of the upper valve head B and accompanying parts;

wings 13 and ports 13 as described in con-f) nection with the valve head"12. The valvef valve-heads are seated said rings 4keep the Huid from leaking out of the perforated pipe10.

The wings 13 of the valve- heads 12 and 14 extend beyond themain body of said heads, as at 17, and act as stops for the .valveheads, andwalso act to hold theispring 15?.v

The seatll is in the form of a collar and screws, on to theupperend of the kperfo-l rated pipesection.10, as wellas to the tube 18. The valve-seat'l ,has the outwardly. extending projections or lugs 19 engaging .the retainer 20 which isscrewed onto the iwer @mi or el@ valve-head' 21, sala valve head being seatedon the shoulder 23 formed by the .upper end of the working-barrel 3.

' The tube 18 passes through the valve-head 21, and said tube passes through the stullingl diferenceV in thetwo valve-headsfis that theI 70 box formed by the gland 24 and the packing 25. .'llhe valve-head21` has the annular groove 26 formed therein and ports 27 in sleeve 28, which connects the the couplin lower-barrelY 3 with the upper-barrel Y29, communicate with said annular'groove.

Passages 30 and 31 are formed in the valve-head 21, said lpassages communicating with the annular groove 26. A valve 32 controls the passages 30, a spring 33 being interpo/sed betweenV said valve and the seat 20. A valve 34 controls the passages 31, and the flange 35 on the` gland 24'acts as a stop con- .grrol ing the upward., movement of said valve Above and below the annular. groove 26 v the valve head 21 is provided with suitable fao packing-rings 36 to keep the luid from leakinby it and the sleeve 28. f-

elow the lower packing-ring on the valve-head 21 is formed the groovev 37 havin'g Xitsbottom wall formed with the camort1ons 39. The segmental blocks 40 fit 1nto this groovev and are held yieldingly therein by the spring-ring 41. The segments are beveled, as at 42, and tit into the groove f43 formed in the sleeve 28 when said segments are expanded by the cam portions 39. The pins 44 are screwed'in the sleeve 28 and project in between the segments 41.

Pins 45 are screwed into the sleeve 28 and project intobavonet slots 38 formed in the valve head.v The vertical portion 46 of the bayonet slot isl formed laring so that the pins 44 and '45 will enter with ease. I-The slot 38 has stops 47 so that the valve-head -21 can only be turned one way, and when turned back the vertical slot 46 will be in.

V 15" are collars, A .throughthem line with the pins 44 and 45, as vclearly shown in Figs. 4 and 6.

The sleeve 27 screws on vto the .Upper end ofthe working-barrel 3, and the upper barrel 29, screws into it except when there is only one barrel vused, when the tube screws into the upper end of said sleeve.

When two working-barrels are used, one above the other, the upper one 29 lis larger in diameter than the lower one 3, rso that the lower one will have the seat23 for the valvelhead 21 to rest on.'

Theupper'duplex valve A is the same as the lower one previously described, and it will not be inecessary to describe the same in detail, but the same `letters of reference will v be used to indicate the same parts,.the only exception being that both valve seats'9a and so that the fluid will pass The upper valve-head B and its accompanying parts are the same as the valve head 21 necessary to repeat the construction indetail, but the same reference numerals will be ud to indicate the samev parts. rllhe only valve-head B is cupped at its upper end, asf

at 49, to form pockets 50 to catch any rivets that may work out otV the sucker-rod strap, fand Asaid pocket furthermore will catch any'sedimentand keep it away from the stutlng-box gland.24.`

previously desdribed, and'it will not be The tube 51is perforated just below `the i source of power for giving the reciprocating` movement to the pump. To insert the valvesandvalve-heads into the working-barrels they are lowered by the sucker-rods until the valve heads rest on their seats 23, whereupon the sucker-rods are turned until the projections 53on the cage 53 engage the recesses 24% formed in the uptions 9b on the valve-seat 9i* engage the recesses 24a in the lower stuing--bo'x gland'24.v

per stuling-box gland 24, andthe projec- 1 j `will force the segments outwardly into the recesses of the sleeves 28, andI the. said Asegments, being beveled at 42; will lock the valve-heads tightly in their seats. vlln case both `valve-headsdo3 not tighten atl the same time, by raisingthe sucker-rods just enough so that the valve-seat lugs 9b will disengage `the lower gland 24 the upper gland will still fbe in engagement with the projections 53a on the cage/753, dueto the fact that said pro-- jections 53a are longer than the projections or lugs 9b. Asl a consequence, the upper valve-head can be turned independently. of..

the lower valve-head and a proper seatmg of both`valve-heads canfthus be obtained. Where it is desired to adjust the lower valve. head 21 independently of the upper valvehead, the sucker-rods are raised until the' projections 19 on the valve-seat lpengage `Jthe necesses 13b in the valve-stop 20. ln the above manner both valve-heads may be turned at the same time or independentl ofJ each other, as desired, in order to fix t em properly in their seats. V

The pump is now readyto operate, and upon the up-stroke the fluid forces the valves 14 from their seats, thereby compressing the springs 15a, and the fluid `passes into. the

tube 10 through the perforations formed therein, whence it passes up the tube 18 and out through the openings in the cage53. At the same time, fluid enters the valve 7 and the upper'valve 34 lets' the fluid into the lower end of the noo 'noalll Iduring the up-stroke the v Vze I f barrel 29, said fluid being admitted by the openings 26 and 27 in the valve-head 21 and sleeve-28, respectively.

On the down-stroke the fluid forces, the valves 12 from ther seats, the valves 14 being closed by the action ofthe springsl,

l and fluid passes through the ports 13El intothe'perforagted pipe section 10 and thence into the pipe 18 to the cage 53, and thence tc the top of the wel1. Byl the employment of these ports 13a greater opportunity is given to let the fluid getaway and prevent com-y pression of said fluid between the valve heads 12 and 14. i

When it is desired to remove the valveheads and valves "from the barrels, it is only necessary to lowerthe sucker-rods untiLthe projections 53a and 9b enter the seats 24a in the glands 24, whereupon by` turning the sucker-rods the segments 40 are released and permitted to collapse, so that the valve-heads 21 are disengaged from the pins 44 and 45 in the sleeves 28, and by pulli/ngup on the sucker-rods the vvalve heads are readily withdrawn for vpurposes of repair or any other reason.

By my invention'I provide a double-acting pump in which the fluid is raised byboth up and down strokes, and inl which the parts are all contained within the barrels, thereby doing away with any outside con- I nections such as pipes for by-passing the uid which complicate the construction and increase the cost. l Y

Furthermore, by duplicating the parts in the manner illustrated. the capacity is in, creased nearly four-fold over the ordinary single pump, and yet the valvesand ,intermediate and top valve-heads may be withdrawn without pulling the tubing and vworking-barrels; But lonly where one'working-barrel isyemployed andthe top valve head is used the capacity of the pump will be increased nearly two-fold over the single-acting pump. When the fluid is pumped belowtheuppe pumpgit will then pump the gas that is saturated -with the gasoline vapors alongn 'with the oil that the lower pump pumps.v

This gas can be separated in the usual manner and put through a compressor o r other means for extracting the gasoline.n What Iy claim is: 1.
