J. PETTlT PUMP VALVE Filed Oct.. 27, 1923 Patented Mar. 10, 1925.

UNITED STATES JOHN PETTIT, E BARTLESVILLE, oKLiirrc/lvra PUMP VALVE.

Application filed october 27, 1923, Serial No. l671,151.

To all whom t may concern:

Be it known that L'JOHN PETTIT, a cit-izen of the United States, residing at Bartlesville, in the county of Washington and State l of Oklahoma, have invented certain new and useful Improvements in Pump Valves, of which the following is a specification'.

This invention relates t'o a valve mechanism employed in wells in which sand and l0 the like is commingled with the fluid which is being pumped, and has for one of its objects to provide a simply constructed attachment whereby the sand and the like is prevented from settling'or accumulating in the valve chambers or upon the valve packings,

or other parts, but will be constantly and au- Y tomatically agitated and discharged with the fluid which is being pumped.

Another object of the invention is to pro- Vith these and other objects in view the invention consists in certain' n-ovelvfeatures of construction as hereinafter shownandl described and then specifically pointed out in the claims, and in the'drawings illustrative of the preferred embodiment of the` invention- Figure 1 is a vertical section of the improved device.

Fig. 2 is an enlarged plan view'of the centering device for the tubular conductor member.

Fig. 3 is a plan view of the combined cou- 'pling and bottom of the sand chamber with the agitating tubes in position.

Fig. 4 is a side elevation, partly in section, of the parts shown lin' Fig. 3.;

In most oil wells, and the like, quantities et Saad. .are @reminded 'with theiludand vide a device of this character in whichy being heavier than oil, settle on the pump parts, and unless removed or discharged with the oil, seriously'damage the packings or cups on thework-ing valves and rendering it necessary to pull the pump valves tor55 renew the packing, at frequent intervals, which is a serious obstacle 'anda source of annoyance and expense.

With the improved attachment herein Y shown and described, the sand or the like which may be commingled'with the fluid being pumped is constantly and automatically agita-ted and thereby prevented from settling in the valve chambers or upon the valves 'or the packing, but is discharged with the flow through thepump. y

The improved device may be adapted to various forms or construction of pumps, but for the purpose of illustration is shown applied to the operating 'Valve portion of a conventional pump structure, comprising a lower barrel member 10 having a wear lining member 11, the'm' embers 10 and 11 being coupled to a lower'coupling ring 12, in which the upper end of the tubing anchor is 7. connected and represented at 13. 1 Threaded into the coupling ring 12 is tubular wear or f lining member 16,` and' threaded upon the v upper end 'of the wear member is a guide sleeve 16 and coupled' to the upper end of the lower barrel 10'is'a sleevel which is closed at the upper end except for a rela tively large central internally threaded opening to receive the lower end of a tubu-` lar member 16, and a plurality of smaller openings encircling the larger central opening. Y.

Coupled to the upperend'of the sleeve 15 is an upper barrel memberlS, the latter being coupled at its upper end by a collar 19 9o to the well tube, a portionof which is repre:

' sented at 20.

At its upper end the tube 16 is coupled to a perforated annular centering member 21.

Fitting within each of the apertures of the member 15'is a relatively small tube 22, each of 'the tubes being turned over into `a half circle with the discharge ends pointing downwardly, as shown in Figs'. 1 and 4. Any required number of the tubes 22 maybe 2511i threaded stud .indicated at; 32 ato'.= receive l.the
