OIL-WELL' ATTACHMENT.
Laie-sea Specification of Letters '.Eatent.
Patented Apr, i8? i922.
Application filed December 8, 1920.- Seral No. 429,086.
l'e it known that l, lllinnnxn E. HANCOCK, a .citizen ot the United States ol irme-rica, andresident ot Tulsa, in the county ot Tulsa and IState of Oklahoma7 have invented certain new and useful lniprovements in Uillilell ttachments, of which the following is a specilication.
This invention relates to oil Wells and anoilivell equipment and partie-ularli7 to improvements in the valve and Valve controlling elements employed during the pumping operation in oil Wells, the said' imfentionv having for its object the provision of novel' means-tor dislodging or removing accumulations of foreign sub-stances Whichmight he interposed between the valve and its seat and which might permit a leakage of oilbeing vpumped so that it would not he held abovethevalve While the return stroke off the piston or lifting element was occurring.
)i still further object ot this invention is to provide a valve for the purpose indicated associated with a traveling member adapted to receive an impact troni the piston ot' the pumping elements to torce the valve toward its seat and crush any sand or other Yforeign clement Which impaired the operation ot i the valve.
A still :further objectoi" this invention is to provide an attachment 'for a valve cage in suchl operative relation to the uilve as to force the valve toward the seat ttor the purpose indicated and to so position the said attachment as to he in operative relation to a recii'nocating element such as the piston or sucker as tov make it possible to impart the niotion; oi the said piston or sucker to tho element.
lll-lith the foregoing and other objects iu riem the inventicm conta. in the details otconstruction and. inthe arrai 'minent and i parts te he hereinafter more u and claimed. l
In describing the invention in detail; reterence will he had to the aceonipanyingy drawings forming part of this aplilication `wherein like characters denote corresponding parts in the several views, and in which Figure l lillustrates a sectional View of a Working barrel and the pumping elements associated therewith;
Figure 2 illustrates an enlarged sectional View of the valve and means for Jforcing the valve to its seat;
Figure 8 illustrates a sectional View on line corresponding with the line 3-3- oiIv Fig. l; and
Figure il illustratesa sectional vieu' on a line correspendingY with the line 'll-l ot Fig. 2. i
ln. these drawings l have illustrated a Working barrel. 5 haring aV series oft' tuhings 6 and 7 therein and couplings such asS and 9 hv. which: the parts are connected together, and l have also illustrated the means lor collecting sand Wh ich mayv he present in the oil being pumped, lout as the sand arresting construction forms a. part et anotheru application oi,E mine? a description. of the details ot construction of these parts Vwill not be attempted The tube 6 has a collar l() secured on it which collar haslugs ll radiating therefrom, and hearing against the inner. Wall barrel to hold the-tube 6 in spaced relation to the barrel.` and there is also a collar l2 ot similar construction hut of larger here fitted to the tube 7'. The piston .i3v and its rod lf-flof Ordinar)T construction and Werl-ein lthe tube 7 during the' pumping operation. The valve cage 1.5. which7 genf llyv speakingn is of standard construction. a coupling ttl by which it is connectedto the tube t3 and this coupling has avnipple 17 threaded in the valve cage and a tapered' threaded here 18 by which it is connected to thetuhe t3. The valve-cage has the usual; valve seat l9-and Valve- QO which in practice. as heretofore stated, sometimes becomes uneated by thc inter-position ot 'toreign 'suhstances such as sand. the sand or material which interferes with the action ot the valve, the top ot" the Valve is provided with a tl readed aperture 2l inr which a hollow hushi .flu'eadr-nl through which f said p in r te! i a h .i to ahnt the valre. and torce it to l i. plunger has a threaded end 26 on which nuts 27 and 28 are threaded and there is a disk 9,9 on the threaded end ot' the plunger-located between the two nuts, and these nuts and disk form What may be. termed a head adapted loe struck by the piston, under certain conditions, during the pumping operation. The plunger is held normally projected by a spring 30 Which encircles the said plunger and hears against the upper end of the bushing and the nut 27 and therefore, the plun- 't thev ger is yieldably held projected and. automa tically returns to its normal position shown in Fig. 2.
Ordinarily during the pumping' operation and when there is no impairment of action of the valve due to deposits such as has been mentioned, the stroke of the piston will terminate free of the upper end of theplunger, but as is well known, provision is made, through the use of a turn buckle or such eX- pedient, for increasing or diminishing the stroke of the piston'rod and hence by lengthening the piston rod through. the use of a turnbuckle, the stroke of the piston could be made such as to cause it to force the plunger downwardly into engagement with the valve and after the valve has been caused to resume its normal operation, the turnbuckle could be 1re-adjusted for the normal lstroke of the piston. y
lt follows, therefore, from an inspection of the drawing and from the foregoing description, that the device embodying the invention may be installed in wells now in operation by substituting valve cages of this type for those now in common use.
It is also shown that the hood or deiiector 31 is supported on the valve cage and held thereon by a-nut 32 threaded on the external surface of the bushing. |This hood in the present embodiment ofthe invention is -flared toward the bottom or mouth, although it may -be straight ifdesired.
I claim.:
