A second nut commonly used in connection with the nut 40 is replaced by ahook member 41 having a threaded socket42 in its upper end for engaging the shaft and havinga pair of depending lingers 43 provided with hook portions 44 to cooperate with the cross pin 35 of the standing valve cage when the cup plunger is lowered' sufficiently into the working barrel, as when withdrawing the standing valve from the pump.

Threaded on the upper end of the shaft 37 is a traveling valve cage 45 retaining 'the usual-ball valve 46 and having a threaded socket 47 in its upper end for receiving the lower threaded endy 48 of a connecting rod 49 which is slidably mounted in a packer 50. Formed near the upper endof the rod'49 is an annular shoulder 51 spaced slightly from a head 52 providedon the rod adjacent its outerthreadedend 53. Engaging the threaded end 53 is asucker rod section 54 extending upwardly to the reciprocating mechanism at the upper end of the well for lowering and `elevating the 'pump plunger in the working barrel. Y r' y TheV packer 50 includes axc'ylindrica-l housing 55 having an inner chamber56 terminating in a tapered seat 57 for receiving packing material 58 urged into the chamber by a gland 59. Formed on the lower end of the packer housing is a reduced tubularY shank 60 for receiving a pair of cups 61 spaced by a cup ring 62'and retained on the shank by a nut 63 and a lock nut 64. Y

Attention is called'to the packer housing which is .slightly greater in diameterthan the internal diameter of the working barrel so that entrance of the packer into the working barrel will be limited, the cups 61 serving.

to frictionally engagek the working barrel, thereby preventing retractionof the packer from the working barrel under ordinary conditions.

By providing the packer in the upper end of the working barrel, liquid pumped from the well cannot pass upwardly Ythrough the barrel4 and into the tubing but `is bypassed as now described.

Provided near the upper end ofthe barrel, but below the coupling 9, arev annular series of po-rts 65, and formed in said coupling around .its concentric opening 10 are ports 66, so that fluid elevated by the pump plunger passes from the working barrel through the ports 65 and upwardly through theV ports inV the coupling.

In this manner, the sand carried by the oil in suspension and settling-in the oil when pumping is discontinued, will be prevented from accumulating on the cups of the plunger. Y

Assuming a pump and working barrel cylinder to be constructed and assembled as described the procedure for inserting a pump plunger into the well would be as follows:

With the pump plunger, standing valve assembly and gas anchor connected as shown in Fig. l, the combined members are lowered into the well with the gas anchor extending downwardly.

As the connected parts are lowered into the well the gas anchor will enter the collar 21, and the standing valve assembly will be seated in thev inserted coupling A6. Simultaneously the packer cups will enter the coupling 9 and the packer housing comes to rest on the upper edge of the working barrel.

Lowering of the pump plunger is then continued to permit disengagement of the hooks 44 from the transverse pin 35, this disengagement being eifected by a slight rotation of the pump plunger in a clockwise direction,

as will be evident from Fig. 1.

Theassembled pump is now ready for operation and, upon reciprocation of the sucker rods, the pump plunger isA moved upwardly and downwardly in the workingbarrel. As

vit moves upwardly liquid is drawn from the .well through the standing valve, and upon downward Ymovement of the pump plunger the liquid passesthrough the plunger and traveling valve, being restricted from return flow into the well by the ball 46 kof the traveling valve. n

Thegffollowing up-stroke of the pump plunger carries the fluidr upwardly in the working barrel, Vbut due to the packer 55 in the upper end thereof the fluid must pass from the working barrel through the series -of ports 65 provided in the working barrel immediately below the inserted coupling 9.

When the chamber between the workingl barrel and pump cylinder has become filled withoil a continued operation of the pump will force the liquid upwardly through the ports 66Vinthe coupling 9 and upwardly through the well tubing to a point of discharge at the top of thewell.v y Since fluid in the well usually carries a considerable, amount of sand in suspension it is obvious that upon discontinuing operation ofthe pump the sand contained in the oil standing .in the tubing will settle downwardly and YVin pumps of ordinary construction will fill the cavity surrounding the cups of the pump plunger. However, with our present construction the sand will be forced to settle downwardly through the ports in the upper inserted coupling and will come to rest on the upper 'face of the lower inserted coupling, thus preventingk accumulation of sand on the pump plunger cups.

As a result the wear on'the cups-will be greatly decreased and replacement thereof will yrarely be necessary. If it is desired to remove the sand accumulated on the lower coupling itis merely .necessary to lower the c @gemme well tubing until the tubing anchor comes.

to rest on the bottom of the well. By continuing the downward movement of the tub` When it becomes necessary to remove the pump plunger from the working barrel it is elevated until the traveling valve engages the packer and dislodges the packer cups .from the working barrel whereupon the plunger and packer may be readily removed from the well.

Should it be desired to also remove the standing valve and gas anchor the plunger is first lowered and attached to the standing valve by a slight anti-clockwise rotation of the pump plunger to engage the hooks 44 with the transverse pin 35 of the standing valve.
