To all whom it may concern:

Be it known. that I, JAMES RINARD, a

citizen of the United States, residing at Marietta, in the county of Washington and state offOhio, have invented certain new and useful Improvements in Pumping Ap- "jparatus, of whichtheifollowingis aspecific qn-d 1 .j 'My invention relates tolpumps, such as .oil or water pumps,, and has particular ref-,

of illustration is shown a preferred embodiment of my invention, the numeral 10 designates the outer casing, and 11 the working barrel, included inthe tubing. Mounted to reciprocate within the working barrelis a pumping plunger 12, of :the usual construe:

'tion, having the usual check valve 13,:and cups 14.- This plunger is reciprocated: by :the usual plunger .rod 15. 7

The lower. end 0f the working barrel is connected with the tubular anchor '16,f'by

means of a. threaded-fitting or couplingfflf,

The anchor 16 is provided in its lower portion-with the-nusual apertures 20. through whichthe oil, or other fluid to be raised-passes. from the sand, and

enters the anchor. The level of the fluid is above these apertures.

My invention embodies a'standing valve, including an upper tubular portion 21, equipped with cups or packing '22; of the usual construction found upon standing valves. The upper tubular bodv portion is also equipped with the usual valve cage 23'. holding the hall check valve. The numeral 24 designates the lower tubular member. provided at its upper end with a tubular extension or neck 25. of reduced diameter,

which neck is adapted for engagement within a screwthreaded recess 26, in communi- Cation with the bore of the upper'tubular member 21. In assembling the upper and lower tubular members. their adjacent ends are retained spaced for affording an annu lar space or passage 27. for the escape of gases. The lower. tubular bodv portion24 carries a cup or packing 28, secured to its lower end, by means of a sleeve29, screwthreaded upon the red ced shank or extension 30. This sleeve is of course tubular, and constitutes a extension. of thetubular body portion M.- The outer face of the sleeve 29 tapers downwardly. and is adapted to fit within and be supported by. the flange 18.

As clearly shown in the drawings, the annular space or recess 27 is arranged between the upper cups or packing 22 and the lower cup or packing 28, and this space 27 is disposed adjacent aperture or apertures 30, formed in the Working barrel 11, and arranged between the upper and lower packing. The lower tubular body portion 24 is provided with a gas release port 31, extend ing longitudinally thereof, andilea'd-ing into the bore of the same, near its center. The upper end of this port 31 ie'ads into an enlarged port of passa e 32, formed in the upper end of the tubu ar body portion 24 and passing through the face of the shoulder 33. A ball check valve 34 is n oirnted within the recess or bore 33, and when seated, closes w the port 31. As clearly shown in Figure 3,

the space or passage 27 is sufficiently narrow whereby the check valve '34 cannot escape from its recess 32. Y

In view of the foiegoing' description, it will be seen that as thegas and oil enter the lower portion of the anchor 16, and rises therein, the gas is free to pass upwardly through the lower portion the standing valve, and will esdape-azhrough the port 31, recess 32 and apertures 30, to -the casing 10' and may then pass tothe atmosphere; Upon the 'uppei'pnsuct'ion' stroke of the pumpiiig plunger, the valve 34' closes the port- 31, and hence the upper end of the anchor 16 is sealed.- "The creation of the usual partial vacuum within the working bar rel, above the standing valve, causes the fluidto pass through the standing valve and apertures are hence out of communication with that portionofthe working barrel, above the standingvalv'e, and also out of communication with the upper end of the anchor 16, when the check valve 34 is closed. It might also be stated that the device may be converted into aflood nipple, by pulling the standing valve, and removing the ball check valve 34. In the usual equipment, to produce a flood nipple operation, it will be necessary to pullthe tubing, which of course is much more expensive.

It is to be understood that the form of my invent-ion herewith shown and described, is to be taken as a preferred exaiilple of the same, and that various changes in the shape, size, and arrangement of parts'ma be resorted to without departing from t e spirit of my invention or the scope of the siibjoined claims.
