'r'ouniy ol linien., Territory ol' Xew Mexiio. have in- Ventei'l eert-nin new and useful improvements in Pump-Valves; mid l do herelry declare the following lo he a lull. lean-and exact deseription ol' the invention, sur-h will ennhlo others skilled in the art to which it appenninol to make and use the salue.
This invention ha relation to hoistingpuinps, and pariieularly lo the valves or vulve-provided huf'kets in Ilze cylinder or peusioelr through whieh the watery oil or other liquid is raised. l
lt is the ohjei't oi the invention to so improve the Standard and piston valves that the saine may not only he prevented from beeoming inoperativehy rete son of iin obstacle accidentally or niisehievoufzly dropped into the'pensto -k, hut that the valven may free themselves from said obstacle. and allow it to eventually be dropped to the bottom oi the wells'. To provide for this the hars composing the valverztges are so d isposied asi to 'have wide interspm'es oi-eur between eneh two of them. whieh wide interspar'en extend down to the plane ol' the valve-seat, and av wide spare is lel't, in virtue ol' the eonstriution. hetw'een the valve-frage and the pump cylinder, ahove the valve Seat. i l
Other objects :mdudvantages Will he apparent from the following deseription` and il. will he understood that uiodilications of the specific vonstriu-Iion shown may he iliade, and any suitable materials may be used without departing from the spirit of tlul inven tidn. 'In the dnrvirings 'forming a portion of this spez-inea-y tion and in whirh like numerals of reierenee indiiato similar partsin the Several views, Figure 1 is a longiudinel Section oi the cylinder or penstoek, showing the standard or step valve, and the pistou or *notion vulve separated Fig. 2 is a transverse section taken on the line'iZ 2 ol' Fig. l, showing the relative Aizo of the hall valves and the dia-meter oi thil rage above the velvet ami their'seain. Fig. 3 is a View similar to Fig. lV hut rep'rwoning the pieton vulve im (winner-ted to the standard and Valve, as when it is proposed to withdraw the latter, and representing;v .i nail :is an mhd r11-"tion naught iu one ol' the valves and reruleriugv il inoperative lor the time heine'. y
itelerring now more Speeifeally to the drawing/s, there. i shown n. pump eylinder 5 provided with the standing valve Sand :islidahlyinounied piston (i which ineludeo thiA working Valve 7. End-h ol those valves. is in reality 'two Valves; flirposed one above the other. The standingfnlve and the piston are Similar in general arrangement und ermeruetion, hoth heine ylindri al in forni and both heing'redured at their upper ends, the
piston terminating in a coupling.; nere-W Q for engagement with a pump rod, the eoupliiu;y Screw lic-ing engaged in a threaded recess a in the upper end ol the piston 6. The rednied portion oi the standing valve io inflieai'ed at l() and is extorifnly threaded for :t purpose to be presently deseriher'i.
The piston (i and the standing valve 8 each centriste of an upper section b, and a lower Section c, which aro hollow and which are longitudinally slotted as shown at l5 to form valve ages 17 andl respectively. The lower end of each of the sections (i has an inwardly extending iange d which is interiorly threaded [or the reception of the upper red ueed end e of the eorresponrt ing lower section c. The lower eer-tions r are interiorly threaded at their lower ends, :is shown atf, and engagged Witn these threuds oi the pistons there ie a cylindrical member g having a passage h formed therethrough which communicates with the interior of the sections c Centrally of the bottom thereof, the upper end of this passage forme a valve seat 13 for the reception of a ball valve i4 disposed within the section c oi The piston, Similar hull Valves 14 being diiposed within the sections b of hoth the piston and standing valve, :1nd resting normally upon seats 12 formed at the upper ends of the reduced portions e of the soetions c.
A shoulder 'L surrounds each of the redueed portions a, and engaged between these shoulders and the adjrteent ende or' the Sections b are packing Washers 2O of suitable fibrous material which are dirmted upwardly, es shown. T he member g is provided with. :i plurality of Circulnncrioing grooves g in which are engaged parking washers 21, similar tothe parking washers 20. The outer laces of the several sections of both the standing valve and the piston lie llush with each other, as shown.
Engaged with the threads f of the section r of the standing valve, there is a dim'nwardly tapered dnd piece k haf. ng an inwardly extending (lange i at its upper end which forms a bottom for this section c, and which has at openingm therethrough having a valve neat 13 at itic upper portion upon. which there rests a ball valve lli/ similar in every way to the balls llt. There are thusrfornied a plurality of upwardly opening valves, and it will be observed, that if a nail or other similar artiile enters the eyliil'der, it will be unable to unseat more than one valve :it a time, for the reason that the valves are disposed a considerable distance apart, and it will therefore be Unpossible for suoli an article toeffect the operation Vol the pump. ll'ie mene her g is provided with an interior-ly threaded reeess ll, the threads o which may be engaged with the threads of the reduced portionl() when it is desired to remove the standing valve from the pump. l
The Blotting of the several .Geetioi'is resulis in a plurality of spared finger.. 3.6 which forni the ball nages, and these fingers of the sections c are-provided with inwnrdly extending triangular hall stops 19 which pre Vent halls loezxted tlrerehelow from rising; and tilling the passages formed through the portions C.
The end pieee is provided with nn interior layer of peeking 22E which tits within the lower tapered end of the eylinder 5, und the cylinder is provided with 'a lining 22.
`lt will'be noted from the foregoing, in view'uof the drawings, that the enge of eheh valve or valve-provided hueket, bolli in the standard valve und in the piston 0r sueker vulve, is larger in dinineter above the vulve Sent than is the mill vulve which Closes upon the Sent` Again, it is to he kept in mind that the piston-vulve as Well as the standard valve is of dual eonstruetion--thait I is, eaehvnlve is provided with two hall-vulves :intl two l enges, ezreh having n. valve seat with wliieh its particular ball valve coperntes. As these valves are in their nature eheclevalves, :1nd :is ezreh operates in the rianne Way, it. will he understood that'if one of the piston' valves becomesinoperative or one oi the standard vulves is rendered ineffective hy reason of en ohstruetion, sueltas n nail, shown in Fig. 3, coming inte 'engagement therewith, the other valve will oper-ate und the effect,- iveneas ef the punip will not he interfered with. 0n
the next; suceeeding operation oi-the pist/on vulve, however, the ball valve interfered with hy the neil or other obstruction will be raised inte the enlarged diameter of the vuli'e enge und the nhslruetion will he freed from l the vulve und lle allowed to drop down out of the wny. lf it should inter-lere with the next, valve below, the t latter vulve will free itself therefrom when it` is next operated. This :xt-lion will eontinne until the ohstrnel tion reaches the hottonr ot the penStot-li or well.
i what is elninred is:
