STATES TQM J. BARGER. OF OILTON, OKLAHOMA.
orL-wnLL' PUMP.
Application filed June 21, 1921.
To all whom it may concern.
Be it known that 1, Tom 5 Banana, a citizen of the United States, residing at Oilton, in the county of Creek and Etate of Oklahoma, have invented certain. new and useful Improvements in Oil-l rell Pumps, of which the following is a specification.
This invention relates to pumps for oil wells and other similar wells; and it consists in providing a sand trap below the foot valve or standing valve, to prevent sand which passes through said valve from being drawn upwardly into the barrel of the pump, as hereinafter fully described and claimed.
In the drawings, Figure 1 is a vertical section of the lower part of an oil well pump provided with a sand trap according to this invention. Fig. 2 is a cross-section, taken on the line 2-2 in Fig. 1.
The barrel 4 of the pump is provided with a slidable plunger 5 having a. longituilinal passage for the liquid. Only portions or these parts are shown, as they, and the delivery valve and other parts above them, are of any approved construction. A collar 7 is secured to the pump barrel, and a sand. trap 8 is secured to this collar. The sand trap 8 is preferably a long cylindrical vessel, and its lower end is closed by a plug 9 in which the suction pipe 1% of the pump is secured. This suction pipe is preferably made in sections, and. its lower end portion 141- is securedin the plug 9 below its upper section.
A foot valve or standing valve 15 is provided, and is arranged in a cage 16 having a tubular stem 17. The upper end of the suction pipe 14; is secured to the stem 17 of. the foot valve. The valve 15 is preferably a ball valve, but any other approved form oi? valve can be used. A tubular guide 15% is provided, and is secured centrally in the sand trap by means of projecting ribs 19 which support the guide and which do not greatly obstruct the sand trap.
The tubular stem 17 of'the footvalve is provided with a circumferential groove 20, and 21. is leather packing arranged in the said groove. The stem 17 rests on a shoulder 22 formed on the guide 18, but it may he supported in any other convenient way. A guide bush 241- for the suction p1pe 18 also secured in the lower part of the guide 18. The cage 16 of the foot valve has a closed Specification of Letters Patent.
Patented Mar. 7, 1922.
Serial No. 479,244.
The pump plunger is reciprocated in the usual manner, and the oil or other liquid flows up the suction pipe when the plunger is raised. lVhen sand passes upwardly with the liquid it passes laterally through the openings in the cage, and sinks by gravity intothe lower part of the sand trap. passing through the spaces formed by the spacing ribs 19 on the guide. The oil which passes into the pump barrel is comparatively tree from sand, and the sand which accumulates in the sand trap is removed from time to time when it is necessary to raise the pump out of the well.
The foot valve and its stem is removable. and the construction hereinbetore described enables the various parts to be removed and replaced with great facility.
The plug 9 is screwed. into the lower end portion of the sand trap cylinder 8, and it has a socket 10 at its lower end. A length of tubing 11 is screwed into the socket 10. leaving an annular space 12 between it and the suction pipe section 1 1, and forms a support for the sand trap.
The upper end portion of the upper section 1+1 of the suction pipe is screwed into or otherwise tightly connected to thelower part of the tubular stem 17 of the foot valve. The suction pipe section 14 is freely slidable in the guide bush 24, and the lower end portion of the pipe section 14 is screwed into the plug 9 which forms the bottom of the sand trap. so that the bottom of the tubular stem 17 is held against the shoulder 22 in the guide 18. The packing 21 prevents the sand from entering between the tubular stem 17 and its guide 18, and it permits the stem- 17 and the pipe section 1 1 to be unscrewed from the plug 9, so that they can be raised and replaced with. facility. whenever desirable. The packing 21 also obviates the necessity for accurate alinement of the plug 9 with the bush 24- and guide 18. and the guide 18 enables a long sand trap to be provided and one that has a considerable space for holding sand below the level of the foot valve 15.
That I claim is:
1. A pump barrel. a sand trap having its upper end secured to the pump barrel and having a guide at its middle part, a guide bush in the lower part of the said guide, a tubular stein slidahle in the said guide and having a foot valve at its upper part above the guide, and a suction pipe section slidahle in the said guide bush and having its upper end portion secured to the said tubular stem and its lower end portion detachahly connected with the lower end portion oi? the said sand trap.
2. A pump barrel, a sand trap secured to the pump barrel and provided with a tubular guide spaced apart from itand having an internal shoulder, a foot valve cage provided with a tubular stem which is slidable in the said guideand which is supported on the said shoulder, packing material arranged between the said stem and guide, a foot valve in the said cage, and a suction pipe secured to the said stem andremovably c011- nected with the lower end portion of the sand trap.
8. A pump barrel, a sand trap having its upper end secured to the pump barrel, a tubular plug which closes the lower end of the sand trap, a tubular guide secured in the middle part of the sand trap and having an internal shoulder, a tubular stem the lower end portion of which is slidable in the said tubular guide and which rests on the said shoulder, a foot valve carried by the said stem and operating to control the passage of liquid through it, and a suction pipe sectionsecured to the tubular stem and having its lower end portion screwed into the opening in the tubular plug.
In testimony whereof I have aflixed my signature.
TOM J. BARGER.
