PUMP.

Specification of Letters Patent.

Application filed August 1, 1911.

To all 11i/om t may concern Be it known that I, RUooLrH CONRADER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Pumps, of which the following is a specication.

This invention relates to pumps and consists in certain improvements in the construction thereof as will be hereinafter fully described and pointed out in the claims.

Among the objects of the invention is to provide the pump with means for mechanically actuating the valve of the pump. This has heretofore been accomplished, but is accomplished in accordance with this invention in an improved manner. Means are also provided in connection with the mechanically actuated valves for opening the valves of the pump so as to drain the pump for the various purposes for which it is desirable.

The invention also contemplates means whereby the sand settling in the pump may be prevented from packing on the top of the plunger so as to injure the working surfaces.

Other objects of the invention will appear from the specification and claims.

The invention is illustrated in the accompanying drawings as follows:

Figure 1 is a central section of a pump on the line 1-1 in Figs. 2, 3, 4, 5, 6, 7, 8 and 9, the plunger being lowered preparatory to picking up the standing valve. Fig. 2 a section on the line 2-2 in Figs. 1, 3, 4,

6, 7, 8, and 9, the plunger being in normal position. Fig. 3 a section on the line 3-3 in Fig. 2. Fig. 4 a section on the line 4-4 in Fig. 2. Fig 5 a section on the line 5 5 in Fig. 2. Fig. 6 a section on the line 6-6 in Fig. 2. Fig. 7 a section on the line 7-7 in Fig. 2. Fig. S a section on the line 8-8 in Fig. 2. Fig. 9 a section on the line 9--9 in Fig. 2.

1 marks the standing valve fitting. This is provided with the bell 2 at its upper end into which the working barrel eXtension 3 is screwed. The working barrel extension is connected by a coupling 4 with the workingl barrel 5. The working barrel 5 is connected by a coupling 6 with a tube 7.

The plunger 8 operates in the werking barrel, and as shown is wholly metallic. It is operated by a sucker rod 9. A crown 10 is screwed into the upper end of the plunger, the plunger being internally screw threaded of the crown 23.

at 11 for this purpose. A collar 13 is also screwed into the upper end of the plunger and the removable plunger seat 14. is clamped between the collar 13 and the crown 10. The upper edge of the plunger is beveled, the edge in contact with. the working' barrel being higher than The crown 10 is screwed down into the plunger so that the edge 12 forms complete annulus around the top of the plunger. The webs of the crown (see F ig. 3) are V shaped as indicated at 10 so that any sand that may settle in the tubing will not lodge around the crown but will pass into the plunger' and thus may be flushed out of the pump.

The plunger valve 15 has a screw threaded opening at its cent-er into which the extension 17 of the sucker rod 9 is screwed. The extension 17 is of slightly smaller diameter than the sucker rod 9 forming a shoulder 1S which contacts the crown 10 so as to limit the relative movement between the sucker rod and the plunger. 0n the downward movement of the sucker rod, the valve is opened through the movement of the sucker rod and the plunger is carried down when the shoulder 1S contacts the crown.

The standing valve has the usual sleeve 19 on which the packing 20 is arranged. The packing 2O is clamped by the base 21 This base has a flange which clamps the removable seat 22 on the top of the sleeve 19. The standing valve check 24 is arranged in the cage and operates upon the seat 22. It has a screw 'threaded opening' 25 into which the stem 26 .is screwed, the stem extending upwardly through an opening 23a in the top of the crown. The screw is locked in the valve by means of the set screws 27. rllhe set screws extend outwardly from the check 24 into the space between the posts 231 in the crown so that they not only lock the screw in the valve, but also lock the check and stem 2G against turning.

The lower end of the plunger has a strap 28 formed integrally with the plunger, leaving the openings 29 to the plunger'. A screw threaded projection 30 extends from the lower end of the strap 28 and this is cupped in its lower face forming a gland in which the packing material 31 is placed. A flange nut is arranged on the extension 30 and screwed up, against the packing so as to the inner surface.,

create frictional pressure on the stem. As the plunger is reciprocated, the friction on the stem 26 is sufficient to mechanically operate the check 2l so that it is opened and closed through the direct action of the plunger rather than by the pressure of the liquid as ordinarily.

The upper end of the stem 26 has a shoulder 33 which is of sufficient size to engage the strapl 28 if the plunger' is withdrawn. In this way, the standing valve may be withdrawn with the plunger, the shouldered eX- tension is of suicient length, and telescopes the plunger sutliciently so that in the normal operation of the pump, the shoulder does not contact the strap 28.

The check 15 is provided with the downwardly extending arms 34 with the cross piece at the bottom. The cross piece has the perforation 36 in which is slidingly mounted the nut 3T. The nut has the head 38 adapted to enga-ge theV arms 3a so as to prevent its turning in the cage thus formed. A spring 89 is tensioned between the top of the nut and the valve 15, the spring being held in place by a projection l() on the end of the sticker rod at the top and a projection 41 on. the top 0f the nut. rlhe nut 8T is screw threaded so as to engage the screw threads 42 on the top of the stem 26. By lowering the plunger below the ordinary stroke of the plunger, the nut 37 can be brought into engagement with the screw threads 42 at the top of the stem 2G and by turningAV the sucker rod, the nut may be screwed on to the stem Vso that the stem is directly connected. l'n order to prevent the bruising of the threads 42 as the nut is lowered, thenut is yieldingly mounted, as shown, the spring yielding but still exerting suflicient pressure as-to insure the entry of the screw. The standing valve, of course, could be lifted by the shoulder but this in` itself would not assure the opening of the pump valves so as to drain the pump and thus facilitate the lifting of the parts. The stemy 26 and connected parts are so proportioned that when the nut 37 is fully screwed on to the screw 42, the

shoulder

1,8 resting on the top of the crown and the tia-nge nut on the top of the standing valve cage, the check 24 will be lifted from its seat. Observing'liig; 1, the parts are in position tol start the engagement of the nut 37 with the screw 42. It will be noted. that the shoulder 18 is in engagement with the crown and the bottom of the plunger with the standing valve cage. It will also be noted that the nut 37 is lifted slightly but not equal tothe length of the screw 42. By turning the sucker rod 9, kthe nut 37 is screwed down until the head 38contacts the bottom cross piece 35. A further turning of the sucker' rod and the screw lifts the stem 26 and consequently the check 24C. Often all pump,

that is desired is to iiush the well or flush the pump, and this opening of the two valves, especially in connection with the arrangement of the crown 10 and edge 12 of the plunger allows the flowing back of the sand and matter that may have accumulated in the tubing in the well. It will be understood that iuthe normal operation of the most of the sand during the activ-e movement of the liquid is carried with it but where the pumping ceases in deep wells the deposit of sand from several thousand feet in the tubing is what gives trouble.

It will be noted that the yielding screw connection is near the top of the plunger.

. there the sand is allowedto pass back into the plunger. it is apt to accumulate on this connection if it is arranged lower in thej plunger. `Where this happens, the sand clogs the action of the spring and throws out the yielding feature ofthe connection and the advantages arising from it. ln the present construction this is obviated.

l do not claim broadly in this application the strap 28 formed integral with theplunger leaving the openings 29, said strap forming a wrench hold for the plunger nor this structure in connection with a screw threaded valve seat in the plunger as these features broadli7 considered form the subject matter of application #582 ,610, filed Sept. 19th, 1910.
