PUMP.

Application filed January 23, 1911.

Specification of Letters Patent.

Paten ted July Al 5, i913.

Serial No. 604.009.

To all fin/wm t may concer/i f Be it known that l, ltuoonrii (lounlnmn, a citizen of the United States. residing at Erie, in the county of flllrie and State of Pennsylvania7 have invented new and useful improvements in Pumps. of which the following is a specification.

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

More particularly, the invention relates to` that type of pumps used in Artesian wells, especially oil wells, and is directed more par ticularly to devices for connecting the sucker rod with the standing valve so that the standing valve may loe lifted for renewal, repair' or for draining the pump.

The invention is illustrated in the accent panying drawings as follows:

Figure l shows a cross section on the line l-l in Fig. 2. Fig. 2 shows a central vertical section through the plunger and standing valve. Fig. 3 a transverse section en the line 3MB in Fig. 2. Fig. 4 a central section through the plunger. Fig. 5 a perspective view of the trunnion and connected parts at the top of the well. Fig. 6 a central section through the standing valve and working barrel showing the standing valve in an elevated position. Fig. 7 a central section through the working barrel and adjacent parts and showing the actuating means at the top of the well.

l marks the strainer common to pumps of this class, 2 an extension on the working barrel7 and 3 the working barrel proper or that part. of the working barrel having the working surfaces. The extension 2 has the standing valve socket lin which is placed the standing valve 5, the valve having the usual packing G which is to effect a joint. The standing valve crown 7 forms the usual. cage for the standing valve check S.

The plunger 9 as shown is tubular and simply provided with metal surfaces which operate in conjunction with the surface of the working barrel. It has the crown l0 in which is arranged the spider 1l forming the connecting means for the sucker rod connection l2. A plunger valve 13 is secured to the sucker rod connection and operates on the valve seat let at the bottom of the crown l0. rlhe sucker rod connection has the shoulder 15 which limits the downward 'movement terminating in the screw ttl on which the sticker rod 1T is screwed. ln the operation of the pump with this type of plunger' valve, the ojgieration of the plunger valve does not depend on the fluid. pressure, but on the downward stroke of the sucker rod, the valve is forced downward away from this seat, the frictional engagement of the plunger with the working harrel resisting this movement. The collar l5 permits the downward movement of the sucker rod connection 12. On the retllrn stroke of the pump7 the sucker rod connection slides upwardly through the spider 'll until the plunger valve seats. This seating of the; valve not only closes the valve but also forms the lifting connection with the plunger so that with a further movement ofthe sticker rod, the plunger is lifted. l

lt is desirable to lift the standing valvel for the purpose of renewal or repair and also for the purpose of draining the pump. l provide a screw connection between the sucker rod connection and the standing valve by means of which the standing valve may he connected with the sucker rod connection so as to he lifted. I prefer to form this connection with a yielding screw so that as the parts are brought together, the screw, threads are not injured and lvet the engagement of the screw practically assured. A. rod 18 is screwed into the top of the stand ing valve crown l and locked in position hy the jam nut 19. A hitting 20 is screwed on to the top of the rod, this fitting being telescopically arranged within the plunger 9. The fitting has the side guide pieces 2l connected by the perforated transverse portion Q2 in which is arranged ascrew 2 3. rlhis screw is adapted to engage the screw Z-t in the valve l?) as the sucker rod connection is lowered into engagement with the screw 23. The screw 2&3 has the head 25 which slides between the guides 2l and is locked by the guides against rotation. A spring E2G is arranged within the guides and is tensioned against the head of the screw 2.5. The rod 1S has a small projection 27 which extends within the spring to lock it in position and the head 25 has the pro- 105 jection 2S which extends within the spring for the same purpose.

llVhen it is desired to couple the sucker rod connection with the standing valve, the plunger is lowered. and the sucker rod is turned so as to rotate the sucker rod connection 12. As this connection and valve 13 are lowered, the screw 23 yields so as to prevent any jamming or injury of the threads. At the same time, the spring forces the screw upwardly so that the entry of the thread is assured. The yielding movement of the screw 23 is sufficient to allow the lower end of the valve 13 to contact the top of the fitting 20 so that regardless of how the plunger and sucker rod connection may be lowered, the screw cannot be injured.

In order to bring the screw 24 into engagement with the screw 23 it is necessary to lower the plunger to a position on the nut 19 as shown in Fig. 4. As the parts are screwed together, the valve 13 will be secured below the seat 14 and as the parts are lifted the plunger is prevented from dropping down to close the valve 13 by reason of the fact that it is resting on the nut 19.

The tube 31 is connected by the coupling 39. to the working barrel 3 in the usual manner and extends to the top of the well. 'Ihe sucker rod 17 terminates with the usual polished rod 32. This polished rod is attached to the polished rod adjuster. The rod extends into the body 34 and through the eye bolt 35, the eye bolt being arranged in the body. rIhe eye bolt has the projection 3G and the nut 37 is arranged on this projection. By means of the nut 37 pressure may be exerted on the eye bolt so as to clamp the rod in place. The polished rod 32 extends through the eye bolt and as the eye bolt is forced sidewise is clamped in position. This has the ordinary construction for adjusting the polished rod. A screw thread socket 38 is arranged in the top of the adjuster and the pipe 39 is screwed into this socket. A portion at least of the pipe 39 is screw threaded and is screwed through the head 40 ofthe trunnions 41. The triinnions are arranged in the usual bearings on the walking beam 4Q.

IVhen itis desired to lift the standing valve, the walking beam is stopped at its lowest position and the pipe 39 on sucker rod adjusterl is screwed down thus lowering the plunger to a position where the screw threads 24 of the. valve 13 will engage the screw 23. As the sucker rods are turned down, it will be noted that the sucker rod connection 1'2 turns in the plunger so as to relieve the plunger of the turning action. The pipe 39 is preferably provided with a nut 43 for indicating the position where the sucker rod connection is brought into engagement and also with the nut 44 for indieating the clamping position and for locking the pipe in adjustment in the triinnion head.

It is often desirable to simply lift the standing valve and discharge the liquid from the tube so as to clean the valve surfaces or flood the well. By making the extension Q larger than the standing valve and of suflicient length to form a bypass around the standing valve when the standing valve is lifted, this can be readily accomplished without lifting the plunger from the working barrel. In'Fig. 7 the plunger is lowered and the sucker rod connection has been screwed into engagement with the screw 23. In Fig. 6 thestanding valve as shown is lifted into the extension 2. It will be readily seen that the liquid can pass around the standing valve and be discharged. It will also be noted that when these parts are in engagement, the valve 13 is opened so that the liquid from the tube can pass through the plunger.

I prefer to arrange a flange nut 30 in the bottom of the plunger forming an internal shoulder which will engage the bottom of the fitting 20 and thus lift the standing valve. This scheme of lifting the standing valve can be utilized should the screw connection become disarranged, or where it is not important to drain the tubing.

I do not claim broadly in this application a yielding connection between the plunger and standing valve or a yielding bolt on the plunger or standing valve as these features form the subject matter of applications #604,007 and #604,008 filed on even date herewith.
