VALVE nQUIPIlIEN'n` non OIL-'WELL' PUMPS.
Application filed June 8,
' i Our invention relates to deep well pumps of the plunger type intended for oil wells and more particularly to 'valves for such pumps. p p
rl-"he 'common practice in oil pumps has been to fix the working valve on thenl )erV I C end of the plunger andV to lprovide theifstand- 'ing valve witha rod,l nown as a Garbutt rod, extending upwardly therelrcinthrough anut inthe lower `end ot' the' plunger, the nut being adapted tov engage 'the upper end of the Garbutt rod when the plunger is pulled out of the pump so as to lift the standing valve out alongwirth` the plunger. The'etliciency of the-pump, with `this arrangement of valves, o'liten becomes'greatly reduced'by an accumulation'ot gas, between the 'standing valve and ythe working" valve, which by reason of its' great elasticity causes a considerable amountof vlost motion. It has been found'advantageous, therefore, to fix the workingl valve on jthe lower. end of the plunger, its proximity in that position, to 'thestanding'valve being such as to prevent theaccumulation'of any appreciable axnount of' gasbetween'the two valves. p
Thevprimary object of our invention is to provide an improved valve equipment for deep well pumps whereby exceptionally high elliciency and exceptionally smooth action in the loperation'thereoip is attained.
A further object is to providea `standing valve which vis adapted for use' wi th a plungerhaving 'the working valve lined on'its lower end and means associated with the working valve for'withdrawing the standing valve from'the pump along with the plunger.
A further object is to'provide a vdeep well "pump having its Werl-:ing 'valve fixed onthe lower end of' the'plu'nger thereof andneans associated with the working valve vlor rwithdrawing the standing ,valve from Vthe-pump along with the plungenrsaid means being` -a substitute for the usua'lGrarbutt rod.
-Otherobjectsand advantages will appear' hereinafter and while we show herewith and will describe a preferred form of construction, we desire it to be'under'stood that we do not conlineV ourselves to such Ypreferred form but that various changes and adaptations may be'made therein without departing from the spiritV of our invention as here` inafter claimed.

`-Fig.'2 isr an enlarged sectional view of the f standlngval-ve shown inf Fig. 1, the'l section which" is screwed intovthe upperendof the lplung'er againsta j amnut 15.
A ball valve of theclosedtype comprising `a blind cage 1Gv with: a cross-bar `17 tolimit the upward movement oftlieball'lS and -a cage couplingf 19, with a ball seat, in :its
'cage coupling 19 and an 'auxiliary ipolished rod 21 smaller than-the'regular' polished rod lis screwed into cage 20 so as'to extend downwardly therefrom. I
rThe standing valve"22 Ya'inodied form oit the valve shown in our application, filed sept.. 13,1926, una@ senaizNO; v134,987, .for Y a patent ion a freli'eit Vvalve forl deep well pumps. v. It consistsot a' tubularjbody 23, radaptedto seat inthe pumptfubef couplingr 24. -below the plunger "of f the pump, said boldyhaving 'a sleeve25 in the upper end v'thereof which isn-heldinconcentricrelation. y y
loo
v thereto by regularly`VY spacedv radial arms .for partitions 26fso as to provide vertical openings 27' between the body 23 and sleeve25,
through which oil may flow freely. Sleeve 25 is internally screw-threaded and two sleeves 28, and 29, having a diameter which conforms to 'that of polished rod 21, are Y screwed one into the upper andthe other into the lower end thereof, as shown in Fig.
2. The upper ends of partitions 2G are cut away somewhat so that an annular` groove 8O is formed at the upper end of the vvalve body, between sleeve 25 and the body proper, and a ring `lapper 8l having beveled faces 32, adapted to seat in groove 30, encircles guide sleeve 28 and serves as the valve closure. A stop nut and a lock nut 34k are screwed on sleeve 28 above tlapper 31. to adjustably liinit its working space. Radial grooves 35 are cut in the upper end of ring flapper 3l to provide ior` equalization of pressure on the inner and outer sides thereof. The upper and lower ends of valve body 23 are extended to forni screw-threaded iiipples 36 and 37, respectively, and an upper cage 38 and a lower cage 39 are srrewed thereon, the upper one extending upwardly tothe end of guide sleeve 28 and the lower one extending downwardly to the end of guilde sleeve 29A and each.v embracing said sleeve ends respectively.
Vrl`he standing valve thus constructed is adapted to rest in its seat in coupling 24- with polishedv rod 2l extending downwardly through guide sleeves Q8 and 29 thereof. The length of polished rod 2l is such that a kwasher Ll() and retaining` nuts L.'i-l, screwed on its projecting lower end, reciprocate iii the punip tubing below lower cage 39 while the plunger is operating` and coiiie iii contact with cage 39 only when the plunger is being withdrawii troni the pun'ip or is being inserted into it.
rlhe operation of the valves has been suggested in the description thereof. Polished rodf 2l works in sleeves 28 and 29 et the standing' valve. As the plunger nieves upwardly oil drawn through the standing valve into the space between it and the workingl valve, llappei 8l lifting olla. ifi-oni its scat to allow it to pass. lVhen the plunger starts .on its downward stroke tlapper 3i drops bacl and closes the standing valve whereupon oil .flows through the working valve, ball i8 lifting oil' 'troni its scat-and allowing free passage thereto and talliiig'baclr on i ts seat when the plunger starts on another upward Stroh iliuxiliary polished rod 2l serves to effect an exceptionally steady action ot the plun i' when operating and also serves a.J a sub?J itule for the usual (flarbutt rod to withdraw the standing` valve troni the puinp along with the pluiigi-Pr.` The two cages 38 and 39 on the standing` valve serve the double purpose ot holding guide sleeves 2S and 29 in rigid aligninentand also as a protection 'troni possible injury to the working .parts ot the standing valve when being reinoved :troni or inserted into the puinp.
It will be seen, therefore, that a puinp equipped, as shown, with our` improved valves and auxiliary polished rod will operate with exceptionalsmoothness and elficiency and can be changed or repaired with the usual facility. i Y
lfiaving thus illustrati-id' and describedY our invention, we claiiii comprising a ,tubular body adapted tov seat in a puii'ip-tube coupling, aconcentri-c sleeve held in said tubular body by radial partitions so as to forni `a series oi vertical openi.
