PUMP VALVE.

Application led August 6, 1921.

To all whom t my concern:

Be it known that l, Vieron ll. PALM, a citizen of the United States, and resident of Butler, in the countyy of Butler and State of Pennsylvania, have invented a. new and useful lmprovement in Pump Valves; and

ldo hereby declare the following to be a full, clear, and exact description thereof.

ll/ly invention relates to pumps tor deep 10 wells for pumping water or oil.

rllhe object ot my invention is to provide a pump of this character in which the capacity for delivering the liquid trom the lower side of the pump to the upper side 15 is greatly increased over the ordinary pumps now in use for this purpose, while at the same time thev liquid keeps barrel washed clean, and the chances lor sediment cutting the packing rings oit the valve are greatly reduced.

l further object o'l my invention is to 'provide means whereby the liquid leaking past the valve is used to increase the packing action of the packing rings, all as more "fully hereinafter set jorth.

ln the accompanying drawing., Fig. l is a vertical section of a working barrel showing my invention applied thereto with the valve in position on the upward stroke; llig. 2 is a like view showing the position oit the valve on the downward strolfze; llig. 3 is an enlarged vertical section of a portion of the valve showing the packing rings and cups; Fig. d is a plan view ot the pump stop; 5 is a plan view of the pump valve; and Figs. tl, 7 and 8 show details of the packing rings.

ln the drawing the numeral 2 designates a suitable working-barrel at the lower en of which is arranged the lower or standing valve 3 which is of the ordinary type.

The numeral l indicatesV an ordinary sucker-rod section provided with the threaded socket 5 which engages the screw threaded portion 6 at the upper end oit the valve-stem 7. At the lower end of the valve stem 7 is the valve 8. I

Connected to the threaded portion 6 of the valve-stem 7 is thestop 9 which is in the form ot a spider, as shown in Fig. l.

lnterposed between the valve 8 and the stop 9 is the valve-sleeve 10, said valvesleeve having the annular grooves 11 formed therein to receive the packing. This packtt ing consists of the leather or like cups 12 which t down in the undercut portions 13 ,sioned thereby will act the workingI vwhich is adapted serial No. 490,402.

of the grooves 11, and on the outside of sa'id cups, engaging said grooves, are the metal packing rings 14C which are divided along the lines 15, as indicated in Fig. 7. rlhe cups 12 are reduced in thickness, asat 16, so as to leave the spaces l7,and split spring rings 18 are employed which act to force the cups outwardly, so as to, in turn, force the packing rings'll outwardly into close engagement to the inner walls of the workingbarrel. rlhe spaces 17 also provide for the admission of liquid leaking past the sleeve back of the cups, andthe pressure occato force the cups outwardly and so force the packing rings 1d outwardly and prevent leakage. rl`he undercut seats 13 for the cups 12 cause the cups to extend across and pack the lower laces of the rings 14, thereby reducing leakage still further, and they also pack the joints in the rings 111 and the joints 15a between the overlapping ends of the rinlgs.

he valve-stem 7 is provided with the wings 19 which act to centralize the stem, said wings engaging the inner face ot the valve-sleevelO, and the valve-stem 7 is reduced in diameter Ibetween the wings 19, as shown at 19a, so as to compensate for the space taken up by the wings 19.

A metal plug 2O may be inserted in an opening 21 formed in the valve 8, and an opening may be drilled through said plug 2() in case it is desired to leak od part oit the liquid, as is common practice when pumping oil wells.

Extending down the valve-stem 7 is the threaded portion 22 to be screwed into the threaded seat 23 in the standing-valve 3 or in the drop-valve which often rests on the standing valve 3, according to common practice, so that when it is desired to pull said valve the connection is made with the stem 7 and the standing-valve or dropvalve is lifted at the same time that the upper valve is pulled, thereby creating a savingin time and labor.

lVhe-n my improved pump is in operation the lowering of the sucker-rod 4 will lower the valve-stem 7 and the stop 9 will engage the valve-sleeve 10 and lower said sleeve,

while at the same time the valve 8 is moved `from the lower end of away from said sleeve so that the liquid passes u through the sleeve 10 to a point above.

n the upward stroke of the pump the valve 8 is brought up into engagement with the sleeve 10 to shut oil:l the passa e of the liquid through said sleeve, and t e sleeve then moves with the stem up in the working barrel and in this way the fluid is raised up to the top of the well.

rIhe manner in which the fluid passes through the sleeve 10, due to the large inlet, keeps the barrel washed clean, so that there is little chance for sediment collecting around the sleeve to cut the packing rings, but in case of any wear the fluid leak-- ing past will get into the spaces 17 and-so act by pressure to force the cups and packing rings tightly against the inner walls of the working barrel, and so seal the joint.

What l claim is: A

1. In a pump, the combination with the working-barrel, of an integral tubular valvesleeve engaging the walls thereof, a valve adapted to seat against the lower surface of said valve-sleeve, a valve-stem connected to said valve, a centering .spider connected to said valve-stein above said valve-sleeve, having a plurality of radial projections forming a stop, and means for reciprocating said valve-stem.

2. ln a pump, the combination with the working-barrel, of an integral tubular valvesleeve engaging the inner walls thereof, a valve-stem, a valve on said valve stem adapted to seat against the lower surface of' said valve-sleeve, wings integral with said valve-stem engaging the inner walls of said sleeve, and a centering spider having a plurality of radial arms extending substantially the full diameter of'said sleeve and forming a stop for said valve, said spider being carried by said valve-stem above said sleeve. i

3. In a pump, the combination with a Working-barrel, of a valve-sleeve engaging the inner walls thereof, a. valve-stem, a

vvalve on the lower end of said valve-stem adapted to engage the lower end of said valve-sleeve, a stop. at the upper end of said Stem, said stop being also adapted to center said valve stem in the working barrel and a soft metal plug engaging an opening in said valve and adapted to be pierced to permit leakage of fluid therethrough.

4. ln a pump, the combination with a working-barrel, of a valve-sleeveengaging the inner walls thereof, .internally closed annular grooves formed in said valve-sleeve,
