WORKING VALVE.

Application led February 12, 192.3. Serial No. 618,611.

To @ZZ whom t may concern:

Be it known that we, VINCENT P. KILL, a citizen of the United States, residing at Lawton, in the county of Comanche, in the State of Oklahoma, and ORRIN J GAs'rnR, a citizen of the United States, residing at Anadarko, in the county of Caddo, in the State of Oklahoma, have invented certain new and useful Improvements in Working Valves, of which the following is a specification7 reference being had to the accompanying drawings.

This invention relates to improvements in working valves and more particularly to working valves forpump plungers utilized in the pumping of oil or water from wells.

An important object of the invention is to provide in a device of this character a positively seating valve the parts of which are so constructed that the device is relatively long lived and will operate under yadverse conditions, such as when encountering paraiiine, sand or heavy gas pressures.

A further object of the invention is to provide a valve of the type in which the valve stem is directly connected with the pump plunger to be operated thereby to seatv and unseat the valve.

A still further object of the invention is to provide in a device of this character a construction whereby both the valve and valve seat are reversible and double ended so that they may be interchangeably employed, thereby doubling `the normal life thereo Other objects and advantages of the invention will appear in the course of the following description.

In the accompanying drawin wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein like reference characters designate like parts throughout: Y

Figure 1 is a side elevation of a valve constructed in'accordance with our invention;

Figure 2 is a longitudinal sectional view therethrough; land l Fi ure 3 is a transverse sectional view on the line 3-3 of Figure 1.

Referring now more particularly to the drawings, the numeral indicates a pump barrel within which is operativelyv mounted a plunger rod 11 directly connected at its lower end with a valve rod or stem 12. The

'valve-rod or stem 12 is threaded at its upper end, as shown at 13, or connection with the pump plunger rod 1and for the reception of limiting and lock nuts 14 and 15 respectively. The lower end of the stem 12 is threaded, as indicated at 16, for engagement with a member 17 provided upon its ends with ground faces 18, forming the member 17 as a double ended valve. The member 17 is reversible upon the threads 16 and at its upper end abuts against guide vanes 19 formed upon the stem 12 and alfordug therebetween fluid passages or grooves'20.

Mounted about the stem 12 is a plunger barrels 21 of greater diameter than the stem 12 and which is provided at its upper end with an enlarged head 22 producing a downwardly directed shoulder 23 for a purpose hereinafter described. The lower end of the barrel 21 is eXteriorly screw-threaded, as indicated at 24, for engagement by a ring member 25 for maintaining in position about the barrel a plurality of cup leathers 26 and spacers 27, which cup leathers lact in the usual manner to seal the space between the working barrel 10 and the plunger barrel 21. The ring 25 when in fully applied position has its lower end spaced from the lower end of the plunger barrel 21 so as to permit engagement with thev plunger barrel of the upper end of the sleeve 28. The sleeve 28 is formed at each end thereof with a valve seat 29 for coaction with one of the ground faces 18 of the member 17 and is interiorly constructed intermediate its threaded end portions, as at 30, to form a slide for the outer faces of the vanes 19. The lower vend l of the ring 25 is shaped, as at 31, to conform to the valve seat 29 which is arranged uppermost so as to form a tight joint at this point and to protect the valve seat which is not in use from corrosion or abrasion. The valve seat which is arranged lowermost will, of course, be intermittently engaged by the uppermost ground face 18 of the lmember 17 during the reciprocation of the stein 12. ln order to protect the lower face 18 of the member 17, l provide a washer disk 32 of approximately the same diameter as the member 17 and which is maintained in position by a retaining screw 33 directed through the washer disk and engaging in the lower end of the stem 12. This disk prevents direct contact of articles within the working barrel/with the face 18 and iurthermore serves as a retainer to prevent accidental disengagement oi the member 17 from the lower end of the stem.

In the operation of the device, when the plunger rod is moved downwardly, the

, member 17 is separated from the sleeve 28,

the' stem 12 moving downwardly until the limiting nut engages the upper end of the head 12. At this time the valve will be' 15 12 will cause the upper ground face 18 to come into engagement with the lower end of sleeve 28, the valve seat 29 of the sleeve 28 closing the lower endof the plunger barrel and retaining above the valve all liquid which has previously passed therethrough. Upon a seat of the valve becomin damaged, the valve may be removed an -the sleeve' 28 inverted. It the valve face 18 itself be damaged, the member 17 is inverted, in either event a new structure being provided by the inversion.

It will be obvious that by the structure hereinbefore set forth we have not only provided a working valve having a pair of interchangeable seats and valves, but in this provision have provided means for locking the retaining element or sleeve 25 in position and likewise means forI protecting the seats and valve faces which are not in use. It will furthermore be obvious that the structure hereinbefore set forth is capable of some change and modilication without materially departing from the spirit of my invention and we accordingly do not limit ourselves to such Specific structure except as hereinafter claimed.

What we claim is v1. In a working valve, a hollow-valve barrel, packing elements `carried by the barrel, a ring having threaded engagement with the lower end of the barrel and maintaining said packing in position upon the barrel, a sleeve likewise having threaded engagement with the barrel, locking said ring in adjusted position thereon, said sleeve being provided upon opposite ends thereof with valve seats and being reversible in its engagement with the barrel, a stem extending through the barrel bore and capable of limited longitudinal reeiprocation therein, and a member carried by the lower end of the stem having a ground face seating on the seat at the lower end of the sleeve when the same ,l said packing in position upon the barrel, a sleeve likewise having threaded engagement maratea with the barrel locking said ring in adjusted position thereon, saidfsleeve being provided upon opposite ends thereof with valve seats and being reversible in its engagement with the barrel, ak stem extending through the barrel bore and capable of limited longitudinal reciprocation therein, and a member carried by the lower end of the stem having a ground lface seating on the seat at the lower end of the sleeve when the same is at the upper limit of its travel, said ring having the lower face thereof formed to conform to the valve seat at the upper end of said ksleeve to thereby pro tect the same.

3. In a working valve, a hollow valve barrel, packing elements carried by the barrel, a ring having threaded engagement with the lower end ofthe barrel andmaintaining said packin in position upon the barrel, a Sleeve likewlse having threaded engagement with the barrel locking said ring in adjusted position thereon, said sleeve being provided upon the lower end thereofl with a valve seat, a stem extending through the barrel bore and capable of limited longitudinal reciprocation therein, and a member carried by the lower end of the stem and reversible thereon having a ground face formed at opposite ends thereof, the uppermost ground face of the member seating on the Seat at the lower end of the sleeve when the stem it at the upper limit of its travel, and means engaged with the lower end of the stem maintaining said .member` in position upon the stem and protecting the ground face at the lower end thereof.
