PUMP.

Application filed December 8, 1921.` Serial No. 520,823.y

To u/'Z vri/wmf 'it may concern.'

Be it known that I, Jnnnr D. NIKON, citizen oi the United States, residingl at Houston, in the bounty oi Harris and State of H Texas, have invented certain new and useful Improvements in a Pump, of which the following is a spec-ilication.

This invention relates to new and useful in'iproveinent-s in a pump. i One object ot the invent-ion is to provide a pump specially adapted for use in pumping oil from oil wells, and provided with sand pockets disposed to receive sandV and other sediments with which the oil is laden.

Another object of the invention Vis to pro vide a pump having pockets to receive the sedii'nentary matter contained in the oil and which, by collecting said matter, will enable the pump to operate for a greater length of 0 time wit-houtcleaninfrthan is the case with pumps now in common use and which, on account of the consequent reduction of sand friction will cause a decrease wear on the workingparts and the consequent lengthen ing of t-he life of the pump.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a vert-ical sectional view of the upper end of the pump. V

Figure 2 is a vertical sectional view of the lower end thereof.

Figure 3 is a transverse sectional view taken on the line 3, 3 of Figure 1, and

Figure 4e is a side view of a spider einployed.

l Referring now more particularly to the drawings, the numeral 1 designates the standing barrel off the pump and the numeral 2 designates the working barrel.

l These are connected, at their lower ends, 'bv

means of an anchor 3, to which they are screwed at their lower ends in such al inanner as to space the latter concentrically within the former. The working barrel is formed of two sections connected by means of a `collar l which has a clearance between it and the standing barrel and is formed with the spider legs 5 which hold the working barrel centered with respect t-o the standing barrel. Threaded into the upper may be engaged therewith to withdraw the z pump from the bore.

The lower end of the anchor L has an internally threaded socket 9 into which the usual gas anchor (not shown) may be threaded. i

.The upper end of the working barrel 2 is spaced below the bushing 6 and is held centered by means Vof the spider shown in Fig- 4ure 4. As shown this spider isformed with the legs 10 connected by their upper ends by means of the ring 11 and at their lower ends by means 'of the ring The inside of the lower ends of these legs are oii'set forming the shoulders 13. which rest upon the upper end of the working barrel and the reduced lower ends of the legs tit between the standing and working barrels for the purpose indicated. This spider is held in place by reason of the fact that the lower endV of the bushing 6 is screwed down against the ring 11.

The anchor 3 is formed with a fluid passage way 14 into the upper end of which the lower end of the tubular valve anchor 15 is screwed concentric with and spaced from the working barrel 2 and screwed onto its upper end there is a nipple formed to receive the valve scat 17 which is held clamped in place by means oit the cage 18 which is threaded onto nipple 16 and which contines the ball Valve 19 controlling said seat. vThe valve mechanism above described, and carried by the anchor 15 is of such Vdimensions, as to form a. cl'L ance `bctween it and the working' barrel.

lilithiu the upper end of the working barrel 2 there is a hollow plui ier .termed theplunger is reciprocated by a suitable pump jack at the surface of the ground.

The course of the oil is indicated by long arrows and the course of the sand and sedi mentary matter is indicated by the short arrows. f

The suction created by the plunger' dravvs the oil and its sedimentary contents up through the tubular valve anchor l5 past. the valve 19 and on up through the Working barrel, and the oil above said plunger is forced by it on up through the pipe T and discharged from the Well. The construction herein described provides a deep sand pocket 25 between the barrels l and 2 and also a sand pocket 26 between the tubular valve anchor 15 and the Working barrel. The sand contained in the oil above the standing valve will settle down into the pocket 2G, and the remaining` sand, in the fluid being pumped will sett-le down around the Working barrel into the pocket 25. This will prevent said sedimentary matter from clogging the valves and from collecting on the inner Wall of the Working barrel. The Wear on the plunger caused by sand friction will thus be greatly diminished as Well as the liability of the clogging of the valves. Then the sand pockets have become filled the pump Will have to be pulled and cleaned, but this will occur at rareintervals thus dispensing with the necessity of frequently pulling and cleaning the pump, a laborious and time consuming operation.

IVhat I claim is:

l. A pump including a standing barrel a Working barrel anchored Within the standing barrel and spaced therefrom to form a sediment pocket a valve anchor Within the Working barrel and spaced therefrom forming a sediment pocket between them a standing valve Xed to the upper end of said anchor, a reciprocating plunger Within the Working barrel above said valve, means for centering the Working barrel within the standing barrel, said centering means including a spider formed with legs, rings connecting said legs at the upper and lower ends, said legs being supported by the upper end of the working barrel, the lower ring surrounding the working barrel and the upper ring being anchored in the standing barrel.

2. A pump including a standing barrel a. Working barrel an anchor to which the lower ends of said barrels are secured, said barrels being` spaced apart to form a pocket between them throughout the length of the working barrel a tubular valve anchor fixed within the lower end of the Working barrel and spaced therefrom to form a pocket standing valve mechanism carried by the upper end of said valve anchor, a reciprocat- .n plunger operating in the Working barrel above the Valve mechanism, means for centering the Working barrel Within the stand ing barrel, said centering means including a spider formed with legs, rings connecting said legs at the upper and lower ends, said legs being supported by the upper end of the Working barrel, the lower ring surrounding the Working barrel and the upper ring being anchored in the standing barrel. n

In testimony whereof I have signed my name to this specification in the presence of tivo subscribing witnesses.
