WILLIAM B. PINE AND IRA V. MARTIN, OF OKMULGEE,OKLAIO1VIA.

PUMPING EQUIPMENT" FOR WELLS.

Application filed NovemberlG, 1923. Serial No. 675,164.

To all whom t may concern:

Be it known that we, Tillmann B. PINE and IRA V. MARTIN, citizens of the United States of America, and residents of Okmulgee, in the county of Okmulgee, State of klahoma, have invented certain new and useful Improvements in Pumping Equip-- ment for l/Vells, of which the following is a specification.

This invention relates to pumping equipment especially adapted for use in oil wells.

Briefly stated, an important object of this invention is to provide a working ha. rel having` reliable means to prevent floating sand from settling on the packers and rapidly wearing the same.

A further object is to provide a working barrel having novel means whereby to trap the sand upon being directed away from the packers sothat it cannot again be picked up by the fiuid. f

A further object is to provide a pumping equipment which is simple to operate7 reliable in use and one in which the necessity for yfrequently pulling the tubing is overcome.

Other objects and advantages will be an parent during the course of the following description.

ln the accompanying drawing forming a part of this application and in which like numerals are employed throughout the same,

Figure 1 is a vertical sectional view through the improved pumping equipment.

Figure 2 is a horizontal sectional view taken on line 2-2 of Figure 1.

Figure 3 is a detail section illustrating the plunger about to enter the sand deflector.

ln the drawing wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral 5 designates a tubing, the lower portion of which is threaded into an upper bushing G, the said bushing formingI what might be said to be the head of the working barrel.

As illust-rated in Figure l, a tubular housing 7 is threaded onto the lower portion of the bushing 6 and has connection with a lower bushing 8. An inner housing 9 consistituting the working barrel is threaded into the lower bushing 8 and supports at its upper end a hydraulic packing 10, the

said packing being mounted on the upper end of an inner bushing 11 and being confined within a tubular stufhng box 12.

ln carrying out the invention a plunger 14 is slidable through the packing` 12 and is provided ,at its upper end with a caged valve Of course on the upward stroke of the plunger 14 thevvalve 15 is seated and on the down stroke of the plunger the valvel is unseated so as to allow the fluid to enter the tubing 5. i

Attention is directed to the fact that an exteriorly tapered sand deflector and scraper. 18" is mounted on the upper end of the packing 12 and receives the plunger 111 so that any sand on the plunger is effectively scraped from the same and directed through a plurality of vertical slots 19 in the adjacent portion of the packing box 12. lt will be seen that the lower portion of the plunger 1&1 is exteriorly tapered as indicated at 20 so that when the same is lowered it will freely pass through the combined sand deflector and scraper. Also, the plunger 1st is guided by the upper bushing 6 and is held in longitudinal alignment with the member 18 so that the plunger will freely enter the working barrel. By reason of this 'construction it islpossible to remove the plunger for repair or replacement withf out pulling the tubing, av feature very valuable to the inventon.

The usual standing valve 25 is lmounted within the inner housing 9 a suitable distance above the lower end of the housing and is supported by means of an inlet pipe 26.

lnoperation the plunger is reciprocated and any floating sand which settles is directed through the slots 19 into the annular sand trap defined by the inner and outer housings and the tubular stuffing box. Figure 1 illustrates that the upper end of the combined scraper and deflector tapers to a knife like edge so as to thoroughly scrape all sand from the plunger and thereby prevent the sand from settling on the packer.

The sand cannot remain within the upper portion of the packing box as the slots extend a substantial distance below the tapered portion of the sand deflector. Therefore, no pockets are formed within the packing box.

Replacement or repairs to the tubing cartied elements of the invention may be com i l i l veniently made by pulling` the tubing to the surface and the sand may also be removed from the sand trap by pulling the tubing.

It is believed to be obvious that the working barrel is supported a suitable distance above the bottom of the well by a main inlet member 28, the lower portion of which may be perforated.

Having thus described the invention, what is claimed is l l. A pumping equipment comprising a housing, a packing box arranged within the housing and having slots establishing communication 'between the interior of the box and the interior of the housing, a plunger movable through the packing box, a barrel receiving .said plunger, a packing carried by the box and surrounding the plunger, and a sand deiieetor mounted on the packing and directing settling sand through said slots.

2. A pumping equipment comprising a housing having a sand trap, a packing box having slots establishing communication. between the interior of the box and said sand trap, a packing arranged in said box, a plunger movable through said packing, and a barrel receiving said plunger.

3. A pumping' equipment comprising a housing having a sand trap, a packing box having slots establishing communication between the interior of the box and said sand trap, a packing arranged in said box, a plunger movable through said packing, a barrel receiving said plunger, and a combined plunger scraper and sand deilector arranged within said box inwardly of said slots.

i. A pumping equipment comprising a. housing having a sand trap, a pac-king box having slots establishing communication be-1 tween the interior oit the box and said sand trap, a packing arranged in said box, a plunger movable through said packing, a barrel receiving said plunger, a combined plunger scraper and sand deHec-tor arranged within said box inwardly of said slots, and a bushing connected to said housing and receiving and guiding said plunger.

5. A pumping equipment comprising a housing having a sand trap, a packing box having slots establishing communication between the interior of the box and said sand trap, a packing arranged in said box, a plunger movable through said packing, a barrel receiving said plunger, a combined plunger scraper and sand detlector arranged within said box inwardly of said slots, and

a standing valve arranged in said barreh` the upper portion of saitL scraper and deflector being tapered to a knife-like edge.

6. A pumping equipment comprising housing having a sand trap, a packing box iaving slots establishing communication between the interior of the box and said sand trap, a packing arranged in said box, a plunger movable through said packing, a barrel receiving said plunger, and a combined plunger scraper and sand deilector arranged within said box, inwardly of said slots, said scraper and deliector being exteriorly tapered for directing sand through said slots, the lower portions of said slots being located below the tapered portion of said scraper and deflector.

7. A pumping equipment comprising a housing having a sand trap, a packing box connected with the housing having slots af'- fording communication between the interior of the box and said sand trap, a packing arranged in said box, a plunger movable through said packing, a barrel arranged within the housing, said barrel being connected with the packing box and being arranged to receive said plunger, and a combined plunger scraper and sand def-lector arranged within said box above the packing andY inwardly of said slots.
