' Application March so, 1935, serial No. 13,960
' 1o claims. (c1. 10s- 179) pump is shut down, and in which the descending sand and the like cannot accumulate around valves, cups, etc., to damage the same.
, With the4 foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by `reference to the accompanying drawings.
Fig. 1 is an elevation partly in section of a pump constructed in accordance with the invention.
Figs. 2, 3 and 4 jointly disclose a longitudinal sectional View through the pump.
Fig. 5 is a vertical sectional viewof the coupling sleeve to'fwhich a sand collecting pipe, a sand and oil conducting pipe, and the working barrel of the pump are connected.
t Fig. 6 is an end elevation of the coupling sleeve shown' in Fig. 5. Y
A preferred construction has been illustrated and will be rather speciiically described, wit-h the understanding however, that within the scope of the invention as claimed, variations may be made.
A cylindrical coupling sleeve is denoted at I Il, said sleeve being provided with oil inlet openings II and with internal tubular oil inlet means Ii* whose ends communicate with said openings, said tubular means I2 being provided with an up- .st-anding sleeve-like boss I3 which communicates therewith, the lower .portion of said boss being downwardly tapered internally and constituting a standing valve assembly seat I4. Preferably, the openings II are two in number and are diametrically aligned, and the oil inlet means I2 isf in the form of a diametrically extending tube integral with vthe coupling sleeve I0 and integral with the boss I3.
` A sand-collecting pipe I5 is threaded into the lower end of the sleeve I0, the lower end of said sand-collecting pipe being closed by a plug or the like IG. A sand andoil conducting pipe I'l is threaded into lthe upper end of the sleeve I0 and extends to the'upper endof the well. This pipe need not be of uniform diameter throughout its length but may be reduced at a suitable point above'the principal traveling parts of the pump. A working barrel. I8 is threaded at its lower end into the upperl end of the boss i3, and a standing valve assembly I 9 is secured in the usual way in the lower end of saidworking barrel, said assembly being provided with a tapered lower end 20 engaging the seat I4. The working barrel I8 receives a tubular plunger 2l having a traveling valve 22, and an oil conducting tube 23 is conv nected to the upper end of the traveling valve cage, said tube 23 extending a suitable distance above the working barrel I8 and being provided at its upper end with a second traveling valve 24 to which a sucker rod 25 is connected, the cage of the valve 24 being of openwork form and dis- 10 charging into the pipe I1 whereas the cage of the valve 22 is of. closed form and communicates only with the tube 23 and the plunger 2l.
A guiding. sleeve 26 is'provided for the oil vconducting tube 23, said guiding sleeve being tightly 15 secured in the upper end of the working barrel I8. The sleeve 26 projects above the working barrel I8 and the upper end of said sleeve is relatively small internally as denoted at 21 to slidably engage the tube 23. From the portion 21 to the 20 lower end of the sleeve 26, the internal diameter of the latter is relatively large to provide an oilreceving chamber 28 around the tube 23. Oilconducting passages 29 extend outwardly from this chamber and open through the periphery of 25 the sleeve 26 in the portion of the latter which projects above the working barrel I8. As the pump opera-tes, oil may flow into and out of the working barrel I8 through the passages 29 and chamber 28 so that no objectionable pressure or 30 vacuum will be created in said working barrel above the plunger 2I to interfere with free operation of the latter.
During reciprocation of the plunger 2l, oil from the well enters the oil inlet means I2 35 through the openings Il, ascends through the standing valve assembly I9 into the working barrel I8, flows through the plunger 2|, tube 23 and' traveling valves 22 and 24, and discharges into the pipe I'l. The oil is, of course, pumped 40 on to the upper end of the well and any sand and the like therein may gravitate in the pipe I'I, pass through the coupling sleeve I0 and enter the pipe I5 in which it is trapped. None of the descending sand and the like can enter the working barrel I8 from which it is excluded by the .guide sleeve 26. Both when the pump is in operation and when it is shut down, sand and the like may settle through the oil into the trap I5 and cannot accumulate around valves, cups, etc. to damage the same.
It will be seen from the foregoing that a comparatively simpleconstruction has been provided for attaining the desired end in an effective manner, and While preferred features of construction 55 have been shown, attention is again invited to the possibility oi making variations within the scope of the invention as claimed.v
