UNITED STATES JOHN H. STAYTON BONNER AND MARTIN TQWNSEITD CHAMBER/LIN, OF VI'ICI-IITA FALLS, TEXAS.
PUMP.
Application filed April 3, 1925. Serial No. 20,475.
To (ZZZ 4.0720121. it may concern:
Be it known that we, J OI-IN H. STAYTON BONNER and h lnirrrx TowNsnNn CHAMBER- LIN, citizens of the United States, residing at W'ichita Falls, in the county of Wichita, State of Texas, have invented certain new and useful Improvements in Pumps, of which the following is a specification.
This invention relates in general to pumps, especially designed for use with oil wells and aims to provide a pump of this character of such construction as to provide a thoroughly effective sand trap, a gas anchor, and a means for preventing a vacuum sometimes set up in the well from interfering with the operation of the pump, whereby to prolong the life of the pump and render it more etlicient in operation, and less expensive to maintain.
A further object is the provision of a pump having these advantages and capacities and which is of simple and durable construction, reliable in operation, and easy and comparatively inexpensive to manufacture and maintain.
Other objects and advantages reside in certain novel features of the construction, arrangement and combination. of parts which will be hereinafter more fully 'described and particularly pointed out in the appended claims, reference being had to the accompanying drawings, forming a part at this specification, and in which,
Figure 1 is a view in elevation showing one embodiment of the invention.
Figure 2 is an enlarged fragmentary view 11 diagrammatic vertical section of the pump shown in Figure 1, and
Figure 3 is a view in transverse section on the line 33 of Figure 2.
deferring to the drawings the numeral 1 designates the tubing which constitutes the How line and on which the pump embodying the present invention is suspended. Of course the sucker rods operate through the flow line 1 in the usual manner. ing barrel 2 is carried by the lower end of the flow line 1 and at the lower end of the working barrel a standing valve 3 is provided. It is to be understood that the usual plunger (not shown) operates in the working barrel and is actuated by the sucker rods.
The present invention proposes the provision of a casing, designated generally at A worki 4-, made up of sections 5, 6, 7, 8 and 9 suitably connected. The sections 5, 6, 8 and 9 are cylindrical and are tubular but the section 7 while cylindrical is not tubular although formed with a number of openings as will be hereinafter more fully described. The section 7 provides a partition which divides the casing into an upper inlet chamber 10 and a lower chamber 11 which constitutes a sand trap. As shown in the drawings, the upper section of the casing is reduced, as at 5, so as to snugly fit around the tubing 1. A set screw 12 is employed for securing the casing 4 to the tubing 1. The arrangement is such that the tubing 1 and the working barrel 2 carried thereby are eccentric with respect to the casing 1. The section 5 of the casing 4 is formed with a plurality of inlet openings 13, which may or'may not be screened, so as to permit the oil or other fluid to pass into. the chamber 10. The section 9 of the ca ing t has its lower end closed by a plug or head 14, so
that the chamber 11 is closed except for its communication with the chamber which is had through openings 15 provided in the section 7.
A number of tubes 16 are" fitted and held in openings 17 provided thereby in the section 7, the lower ends of the tubes 16 being in open communication with the chamber 11 and the upper ends of the tubes 16 being closed, as at 18, and being located in the chamber 10. The interior of the tubes 16 communicatesdirectly with the chamber 11. but communicates with the chamber 10 only through the chamber 11. Stand pipes 19, which are smaller than the tubes 16 extend up into the tubes to a point adjacent to but spaced from their upper closed ends 18. The lower ends of the stand pipes are connected by elbows 20 to a cylinder 21, the lower end of which is closed, as at 22, and the upper end of which is received and secured in an opening 23 provided in the section 7. Just above the upper end of the cylinder 21 the valve seat 3 for the standing valve is provided and as shown in the drawings this valve seat 3 may be a part of the section 7. The lower end of the working barrel 2 terminates above the valve seat 3 and the working barrel and cylinder are in alignment.
With a pump of this character the fluid passes through the openings 13 into the i) it chamber and from the chamber '10 down through the openings into the chamber 11. Ihis downward coursing of the fluid tends to precipitate; sand or dirt to the bottom of the chamber 11, especially-as th fluid after passing downwardly into the chamber 11 must change its course and move up through the tube 16, After travelling to points adjacent the tops of the tubes 16 thefluid again reverses its direction of flow and moves down through the stand pipes 19 and elbows 20 and into the cylinder 21. Again the downward course flow of the fiuid tends to precipitate sand, dirt, ,or the lil e, in the cylinder 21, especially as the fluid after entering the cylinder 21 while flowing downwardly must reverse its direction of flow and pass upwardly through the standing valve 3 into the working barrel 2. The arrangement shown not only has the effective action just described to trap the sand, but the standing valve being isolated from the well by the double column of fluid,
and subjected tothe weight of said column.
of fluid, will not become stuck by virtue of the vacuum in the well. hiloreover, the arrangeme-nt provides a. gas anchor so that in the one device there is the combined action of a sand trap, gas anchor, and a means for preventing the vacuum from interfering with the operation of the pump.
We claim:

In an oil well-pumphaving a working barrel provided with a. standing valve, a casing enclosing the working barrel, said casing having a section dividing the casing into an upper inlet chamber and a lower sanjdtrap. chamber, a tube mounted on. the section and communicating at its lower end with the sand trap, chamber, the upper end of the tube being closed, a stand pipe extending up into the tube and. communicating with the upper part ofthe tube at, its upper end, and a cylinder connected to the working barreland, communicating with; the lower end of the standpipe at its lower end.
