To all 'whom 'it may concern:

Beit known that I, MARSHALL J. MoRToN,

a citizen of the United Statearesiding at Los Angeles, ,in the county of LosAngeles 5 and State of California, have invented new and useful Improvements in Oil-Well Pumps, of which the following is a specilcation.4

This invention relates .morefparticularly to pumping appliancesfor use in oilwells which produce heavy crude oil carrying sand or Votherso'lids,and comprises novel constructions incl-udin a snap-ring cupattachment and sandsag'rtator.. In such ,wells ing the-leakage thati'occurs on account of the rapid wearing away; of .the inside of the 'workingbarre1, ',and the other being the stoppage than4 occurs from the accumulations of sand Jinside 'the 'plunger and the standing-valve., -I overcome'` these diicul ties byfprovding a plunger having peculiar .arrangement of metal packing snaprings outsldeof the plunger-body; by also providing the standing-valve with external packing-rings; and by providing inside' the plunger a sand-agitator so constructed as to operate 'automaticallyto keep' the sand loose within the plunger and to prevent the plunger and standing-valve fromgstickin In oilwel -pumps heretofore employed, the standing-valves have been fitted .to the working-barrel bymeans of leathers or babv'alve is 1Withdrawn from its' seat it must be rebabbi-tted or supplied' with new leathers before itvwill again serve its purpose satisfaetorilywithout leaking.

` Heretofore in pumping. wells of the char'- ing-barrel rapidly becomes worn by the action of-the plun er,-andin-time becomes useless .because lo`v the enlargement ofthe chamberV around theplunger, which allows the oil to ow back past'the plunger.

:An object vofthis invention is Vto' provide a pumping appliance which overcomes all of these diiicu ties. 1 v

'59 Aiurther object is'to provide means for preventing the clogging of the pump-valves y.sand or other' solid substances carried i by heavy crude oil.

l V4Another object is to' .provide a ump Yapparatus Qty-attachment. adapted or.' use in worn working-barrels,

two difficulties are to overcome,one be' `bitt, with theresult that when the standing- Y thereby to prolong the life of the working-barrel over that heretofore common.

Another object is to provide a pump in which the standingvalve may'be'withdrawn and replaced from time to time without the necessity of. rebabbitting.

Other yobjects Vof the invention are simplicity, strength, and longer life oflthe appliance. Theaccompanying drawings illustrate the inventiomf fv Figure l 1 4va broken, .sectional elevation of the lower portion of a pump constructed .in accordance 'with this invention and iupo'- sition in a well.

The plunger-body. is made'in sections andl terminates in a solld steelbuttl which is screwed onto the lower .end of la section 15 of the plunger-body, .which section'is externally screw-threaded at its opl osite ends, is provided at its upper end wit a shoulder 16 that may t' the inside-of the unworn working-barrel 3, and is screWed-into'the cage lcontaining the valve-stopper or ball the plunger-body.
