Application led VMarch `26, v1926. Serial Nro. r`97,6 67

' .'My invention relates to deep well pumps 'and more particularly to one forV use in oil wells and of thexed u plunger andl travelling `barrel type, the principal object ot the invention being to eliminate disadvantages inf' ordinary Y piston vcon- .videdv improved details ofstructure, the preferred forms of which are illustrated in the accompanying drawings, wherein l Fig; l isa vertical section vot' an oilwell illustrating a pump of my the well, parts of the pump away for better illustration.

Fig. 2 is an enlarged, longitudinal section thev upper' portion'of the pump, ularly illustrating assembly of the travelling and working barrels. f

Fig. 3 is a similar view of the ofthe pump. Y Y Y f Fig. 4 `is a'detail perspective view of the` being broken bottom end f valve-'pulling crown.

Referring morein detail tothe drawings: 1 designates awell hole,`lined tothe top of the Vsolid4 strata 2 with ordinary casingl. Extending through the well hole into the shot hole 5 is a tube 6, having an anchor seat 7 at its lower'end providedv with `an extension y8 through which oil is admitted to the interior ofthe tube through a standing valve 9, having frictional seating in the anchor member 7.

Fixed to the vtop ofthe standing valve is .f a standing barrel 10 whichextends upwardly to a sufficient height to accommodate the stroke of the pump.

Fixed to the top of thecage of the standing valve 9 and extending upwardly to a point slightly above thetop of the working barrel, is a rod 11 having a head 12 Vat its upper endfor engagement by the crown on the travelling barrel when the latter is pulled, to remove the standing valve along with the balance of the pump. ,l

, Slidable overthe inner and outer surfaces of the standing barrel 10 are inner and outer tubes 13 and 14, threaded at their upper ends onto a tubular valve body 15, having an upper cage 16 for a downwardly seating ball valve 17, and extending at their lower ends to. a point alongl the standing barrel V,head 12 of the rod 11'y when the travelling barrel is raised to -the'tubing '6 is klowered into the well in lis let into thewell and the particrunder iniiuence oi the above the oil sand 3* Y Threaded into the lower lend of*v the inner tube 13 of the travellingbarrel is a crown `19 havingsde ports 20 vthrough whichfl'uid mayfpassV freely to the interior to the tube, ythe-crown having'an apertured 'bottom 2l,

serving" as a guide "for the lifting rod and an open top 22 for guiding therod'and also adapted vfor engagement with the lifting pull the pump. y Y In installing a pump of this construction the ordinaryway; The pump beingv assembled with the standing valve iixedin the lower end of the standing barrel and theV travelling barrel tubes fitted over the standing barrel, Y p standing valve. located in its anchor seat, frictional-contact of the" standing barrel with the travelling Vbarrel'tubes being suilicientto hold the parts together during the` letting in travel, although :adapted for permitting movement. of the travelling barrel over the standing bar-Y rel when the pump is in operation.

lVhen the travelling barrel is reciprocate'd sucker rod, the travelling barrel tubes.y move Vover the standing barrel with the check valve v17 'closed on upward stroke to close the barrel and draw oil into the tube through the standing valve. Ondown stroke ot' the travelling barrel the fstanding valvecloses and the' valve 17 opens pump, but with the advantage that no 95 'plungervalve is employed with its rings and packing, subject to scarring due to the unavoidable admission. of sand between the piston and its'enclosing wall.

' When the pump is to be removed from 100- the well the travelling barrel is drawn outwardly, lifting the crown 19 upagainst the head von the rod 11 and pulling the standing Vvalve from its seat, so that the pump may 105 be removed as a unit. v What I claim and desire to secure by Letters Patent is v 1; A pump of the character described, comprising a standing barrel, a standing valve fixed to the lower endv of the lstand- Q- ing barrel, a travellingV barrel comprising spaced, concentric tubes movable along-the normally Y standing ,for removal therewith, kstanding valve,- Lling barrel comprising spaced' members fixed standing ybarrel upon .extended upward movementof the travelling inner and outer faces of the, standing barrel, a down-check valve on the travelling barrel, and means connected with the travelling barrel and standing valve cooperative to lift the standing'barrel and standing valve upon vextended elevation of the travelling barrel.

2. A pump of the character described, y*

comprising, in combination with well tubing and an anchor member, a standing valve seated in thel anchor barrell .fixed to the standingvalve a headed rod on the a travelling valve, a traveltofthe 4travelling valve and movable as a ',Iunit over -inner'and'outer surfaces ,of the "standing barrel, .and

a crown on the travelthe headed rod ling unit :engageable with valve and to eect removal of .the standing barrel.

L3..'111 a pump of the character described,

@a standing barrel, astanding valve xed to /the standing barrel and having a headed y the travellingbarrel.

' A. Av pump of the character described compr1sing,in combination-with well tubing .and an anchor seat, a standing valve, a

Y gageable, by

the standing barrel and both fixed to the travelling valve for removalr through the tubing with the travelling valve, and means effecting removal ofthe standing valve and standing barrel with the traveling valve and traveling barrel.

5. A pump of the character described c0mprising,;in combination with well tubing and an anchor seat, a standing valve, aV standing barrel connectedwith; the work-` ing valve, a travellingivalve, a l.travelling barrel comprising yspaced tubular :members movable over inner and outersurfaces of the standingbarrel, both lixedV to the .travelling valve for removal through the*l tubing with the travelling valve, a crown-.on the inner travelling barrel' 1nember-anda rod onthe standinguv-alvehaving agheadensaid crown upon extended i up-J -wardrmovement ofther travelling; barrel to effect removal of thegstanding vvalve and i `standingnbarrel with the travelling barrel.
