UNITED STATES JAMES C. DICKENS, OF GOOSE CREEK, TEXAS.

PUMP.

Application filed March 1, 1923.

To all whom it may concern:

Be it known that I, JA nsC. Dionnns, citizen of the United States, residing at Goose Creek, in the county of Harris and State of Texas, haveinvented certain new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to new and useful improvements in pumps for oil wells.

One object of the invention is to provide a pump of the character described equipped with means whereby the standing valve of the pump may beopened and held open during the process of pulling the tubing, so as to permit the fluid in the tubing to drain back into the well bore. v

Another object of the'invention is to provide a pump of th character described having a standing valve and a traveling valve equipped with interlocking means whereby the traveling valvemay be held against rotation relative to the standing valve so that in case the sucker rod should become parted a joint or should become separated from the traveling valve it may be readily screwed together again and the parted sections reunited.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation, and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a vertical sectional view of an oil well pump showing the valves thereof in side elevation.

Figure 2 shows an enlarged fragmentary vertical sectional view of the pump barrel and standing valve therein.

Figure 3 shows a fragmentary vertical sectional view of the standing valve.

Figure 4 shows a transverse sectional view taken on the line 4-4 of Figure 2, and

Figure 5 shows a transverse sectional view taken on the line 5-5 if Figure 3.

In the drawings the numeral 1 designates the pump barrel which is connected to th lower end of the tubing 2 by means of the swedge nipple 3. The lower end of the barrel is threaded onto a connecting nipple 4 beneath, from which depends the usual gas anchor 5.

Within the lower end of the pump barrel and anchored to the nipple 4 there is a valve cage 6 having the ring like seat 7 therein Serial No. 622,065.

which is controlled by the ball valve 8 confined within said cage. The upper end of the cage 6 is formed into a sleeve 9 forming a vertical bearing for the stem 10. The upper end of the stem has an enlarged head 11 providedwith a transverse groove 12. Surrounding thesieeve 9 and the stem 10 and interposed betw en the head 11 and the cage 6 there is the coil spring 18 whose respective ends are overturned as at i l and fitted into sockets in the head and the upper end of the cage respectively. The upper end of thesleeve 9 has the opposing studs 15, 15 andv between the studs are the inside vertical grooves 16. 16, in said sleeve. The stem 10 has opposing vertical ribs 17, 17 whose lower ends are normally held against the respectiv studs 16 by the tension of the coil spring 13, as illustrated in Figure 2. The lower end of the stem 10 has the opposing arcuate clamp fingers 18, 18 which are flexible and whose lower ends are thickened or headed as at 19 to give greater wearing quality.

Working in the barrel 1 above the standing valve there is a traveling valve 20 of conventional construction and which is reciprocated up and down through the sucker rod 21 which is threaded onto the cage, of said valve, as shown, and in the usual way. Threaded onto the lower end of this valve there is a nut 22 which serves to hold the valve cup rings againstdropping oil and this nut also has a depending tongue 23 adapted to be inserted into the groove 12 for the purposes presently to be explained:In pumping the well sometimes the sucker rod 21 becomes unscrewed at one of its joints or from the valve 20. In such case the traveling valve 20 will ordinarily descend by its own weight and rest on the head 11, the tongue 23 seating in the groove 12, and the traveling valve will thereby be held against rotation when it is attempted to reconnect the disconnected joint of the sucker rod 21, said traveling valve thus serving as an anchor to permit the tightening up of the joint or joints of the sucker rod.

It often becomes necessary in pumping oil wells to pull the tubing out of the bore. This is done by elevating the tubing and unscrewing the joints. above the ground surface, one at the time, and said tubing being usually wholly or partly filled with oil, as they are unscrewed this oil will leak out and become wasted and poured over the derrick floor, thus making a disagreeable and dangerous place to work. In order to prevent this I have provided means for draining out the oil from the tubing in the manner described as follows :-l."he traveling valve is lowered and so turned that the tongue 23 will seat in the groove 12, and the as the tubing is pulled from the bore all of the oil within it will drain out through the unobstructed valve seat 7 and no oil will be wasted;

What I claim is 1. In a pump, a standing valve structure including a ring like seat, a cage, a valve confined Within the cage and cooperating with'said seat to open and close the same, a device mounted in the valve structure and formed to engage with said valve, a yieldable seat on which said device is mounted, said device when in engagement with said valve operating to hold said valve elevated above the seat.

2. In combination a pump barrel, a valve seat lined in said barrel, a valve controlling said seat, a cage confining said valve, a valve engaging device arranged in the cage above the valve, a yieldable seat sustaining said device, and means for locking said device against downward movement relative to said cage.

3. In combination a pump barrel, a valve seat fixed in said barrel, a valve controlling said seat, a cage confining said valve, a valve engaging device arranged in the cage above the valve, a yieldable seat sustaining said device, means for locking said device against downward movement relative to said cage when in one position said locking means being inoperative when said device is in another position relative to the cage.

4. In a pump, a working barrel, a valve seat therein, a valve controlling said seat, a cage confining said valve, the upper end of said cage being formed into a bearing having an internal vertical groove, a stem working through said bearing, a lug carried by said stem and adapted to work in said "more, a yicldable member surrounding sa l stem and attached at its respective ends to the stem and sleeve, said yieldable member norn'ially holding said lug out ofalignment with said groove, a stop carried by said sleeve and adapted to engage with said lug to limit the rotation of the stem relative to the sleeve and valve engaging members carried by the lower end of said stem.

5. In a pump, a working barrel, a valve seat therein, a valve controlling said seat,

cage confining said valve, a bearing caried by the upper end of the cage, a stem l-ll ble vertically in said bearing when in on position, means carried by the stem and ca e respectively andlimiting the rotation and longitudinal movement of the stem when in another position, a yieldable member sustaining said stern and normally holding it in said last mentioned position, and valve engaging members carried by the lower end of the stem.

6. A. pump including a barrel, a standing valve therein, a traveling valve reciprocable in the barrel above the standing valve and interlocking means through which the traveling valve may be locked against rotation relative to the standing valve.

In testimony whereof I have signed my JAMES o. DICKENS.
