SPECIFICATION forming part of' Letters Patent N o. 456,128, dated July 14, 1891. Application ledDeceniherll',1888. Serial No. 293,324. (No model.)

To all whom it 'muy con/cern,.- A

lle it known that I, Josemi Damme, of Karns City, in the county of llutlcr and State of lennsylvania,'have invented'a new and useful Improvement in Iumps, of which the following is a specification.

My invention is an improvement in pumps intended especially for use in deep wells, whether oil or water wells, and seeks, among other improvements, to provide, in connection with a trap-valve at the bottom of said wells, 'novel constructions by which said trap-valve may be positively opened when the standing valve of the pump is inserted; further, to provide novel constructions which will effect the opening of the trap-valve on the insertion i ol' the standing valve and will positively close such trap-valve when the standing valve is removed, and, further, to provide other improvements, as will be hereiimfterdescribed.

l'lheinvention consists in certain features of construction and novel combinations dt parts, as will be described and claimed.

In the drawings, Figure 1 is a longitudinal section of a portion of a lwell provided with my improvements. Figs. 2, 3, and 4 are detail views of the trap-valve and mechanism for operating the trap-valve. Fig. 5 is a detail View illustrating the means for preventing baekfiow in ease of breakage of rods; and Figs. 6 and 7 show modified forms of trapvalve and device for operatingr the same, as will be more fully described hereinafter. Fig.

S is a detail view of the nut on the lower endof the plunger, all of which will be hereinal'ter more fully described; and Fig. ll shows the manner of connectingI the tripper -with the standing valve.

In deep wells, particularly oil-wells, when the pumping devices are removed for any purpose the ilow of water and air, the., from the tube back to the oil or water source operates detrimentally. To avoid this, trap- -valvcs have in some instances been designed for use at the bottom of the tubing controlvrling the inlet-opening,` fertile-water, so that vsuch trap-valyes will he closed when the pumping devices are withdrawn; but so far as I am informed such trap-valves are opened and closed with each reciprocation of the pumping-plunger, 'so that the said trap-valve and its seat soon become worn and need replacing or repairs, .which necessitate the removal of the well-tubing. Such operation is difficult and expensive in several ways, since it involves a stoppagc'of work for a considerable time vand an injurytothe well from the withdrawal of the tubing. This injury to t-he'well from the withdrawal of the tubing is especially experienced in those wells inv which gas or vacuum pumps are employed, as on withdrawing the tubing in such cases the air rushes in and it is sometimes weeks before the former production can be obtained.

An important feature of my inventionis the provision of devices whereby the trapvalve will be opened on the insertion of the support or block for the standing valve and will be held open so long as such valve-snpportremains in operative position and will be closed on the removal of the said standing valve, so that the trap -valve is only moved at t'hc time the standing yalve is insorted and `when such part is removed. As such insertion and removalA of the standingvalve only occurs in some instances at intervals of about thirty days, thereis practically no wear on the trap-valve, and snchl'iart, when once inserted, will in the ordi-nary course ofthings wear for many years without needing any repairs whatever.

Before proceeding to the detailed description of the'particular;constructionswhich I employ for secu ring the ends before described, I desire testate with reference to the accompanying illustration that in Fig. l Ishow the pump-mechanism tubing, barrel, or casing valves, tl:c eonstructed I tice tomake them. 4

Figs. Gand 7 show modified constructions of the valve-operating devices and lthe trapvalve, such constructions shown in Figs. G and 7 being to a certain extent equivalents of the preferred constructions shown in'liig. 1.

rlhe well-'tubing A is provided atits lower end with a section di, reduced in diameter, so that the pump devices which fit and operate in such section may be nio/ved conveniently down to and lifted fromsuchseetion, it being only necessary to use addit'ona'l force to s eatroti the said parts" in Yand ,jar 4or dislodge them from such section, they moy-ing freely down 4to and up" from such' section when so desired.

At its lower end'the section cris coupled prefer in praeto or otherwise suitably provided with the trap valve i3, which comprises the valve proper C and the casinggD therefor', the latter being provided witlrflatcral parte (l, and the valve C being journalcd in the casing and having parte c, which regieter in the proper adjnstmentot the valve with theparte 'v d and permit the entry of iluid', or are set out oi' regieter with such parte to stop olf the iiow of fluid through same when the valve is closed. upward tubular extension E, which is slolted longitudinallynt diametrically-opposite pointe at F, such slots being formed -with straight lower portions jf and spiral orinclined' 'upper portions j", the latter forming practically spiral contacteur-facce, the contact with which of the operating' part, which is moved longitudinally, but is held from ro tary movement when in contact with such surfaces f', will cause a rotation or partial rotation ot' the valve to positively open or close the saine, an may be desired. The lower straight portions f ot' the slots arepreferred, because they permit a limited play of the operating part withoutatlecting any variation of position of the valve.

To hold the valve-operating device pres ently described from turning when in contact with the spiral surfaces, I provide the fixed hearings G, which extend adjacent the spiral contact-surface end are engaged by the tripper the latter is moved longitudiy nallyin contact with the surfaces f and hold the valve-operating device from turning when in such contact. The upper ends of bearinge G are pointed, being beveled from the center downward on opposite sides to properly direct the tripper into operative contact with the spiral surfaces f.

ln the. construction shown in Fig. l. the valve-operating device lir is practically a portion or part oil'the standing valve, being` swiveled at its upper end to the lower end ot the main portion or body of the standing valve, which thus forms the Support for the part li, and the lat-ter is formed with depending` arms il and a cross-bar h, connecting such arme near their lower ends, which bar h may or may not be provided with an antifrictien roller or rollers, as shown. 'lhe arms ll have their lower ende` pointed like the upper ends of the fixed hearings (l, and are adapted when lowered to slide down between the Seid parte, as will be understood from the drawings, the bar 7L passing down in the slot l?, engaging the spiral contacteurface and turning the valve to open such valve as the partitie lowered or close it as the said part raised. It will be neen that the" arms-Il',Y meeting hearings G, are guided thereby, so as to properly present the bar h to engage the contact-surfaces f. 4 l

i In ewiveling the part li, I prefer to forni its upper end with a nipple l, having an external annular groove i.. l

Un `the lower end of the standing valve J',

TheA valve C is A forn'ied with an,-

fieaiee I form a tubular extension J, above which is a threaded portion or hearing-j. 'The coup ling-piece li has ils upper end threaded to lit hearingj, and its lower porti-on is cut away at 7:. on one side to receive the nipple l'1 which may' he moved through opening k laterally into the lowerpportionol the coupling, the

' Sion J lits in the ni pplel and holds such part trom lateral movement out through the opening ligand the flange kfitting in groove i, holds the parte I( l from longitudinal detachment. The part ll ie consequentl y ewiveled in position in a simple convenient manner.

rlhe ahove construction of valve-operatlng devices, dac., refers, as will he underetiinxl, to the construction Shown in Figs. l, 2,3, and 'l. 'lhe constructions shown -in Figs. (j and 7 represent modifications, or what may he regarded as, to a certain extent, equivalents ot the preferred construction before described. In Figs. G and 7 'the form of trapva'lve ie different 4lroni that shown in Fig. l, it being practically a damper-like disk having openings l), which may be turned into and out of register with openings 10 in the bottoni plates of the casing ll. lhis forni of valve haa een;

trail f an 'annular Socket lELand thc ease is provided 'above such socket with a spiral hearing 13. The valve-operating device in such caseis a rod 14, swiveled 'to and depend ing from the standing valve, such rod being' formed with an angular' portion l5 to enter the opening 12 and a spiral portion 1U to engage the spiral bearing 13, the parte heingno arranged that alter the part l? has entered socket l2 the portion 1G will engage Spiral hearing 1S and cause-the rod 'hl to revolve, nd :so turn the valve to open the latter' an "the said rod is inserted and close such valve as it is removed.

lhe construction shown in Fig. 7 is sui)- etantially the saine that shown in llig'. 6, the difference being that in Fig. 7 the angu-V lar hearing is provided in the case and the Spiral bearingin the valve, the depending rod being properly formed "o correspond vwith changeof construction. f nthslastconetruction there iS pr ovided a fixed bearing', and the valve has a spiral contact-surface, the depending rod having a portion lo engage the valve J, it will be seen, is suitably packed, and is provided with an upwardly-opening valve j', and when the barrel L is used this standing valve or valve-block J" is usually` turned inte/the lower end of the barrel, such barrel fitting snugly in socket a of the tubthe lower end of the barrel to form or carry the'tripper. This barrel is made quite thin, and the space between itand the tu bingwhen such space is unfilledrenders the bursting of the barrel by the pressure within the barrel a possible and likely. .'lo avoid this I forni a vent'or opening L in the barrel, preferably immediately below the upper packing l, so

vVent any' damage to the barrel.

Athat the oil or waterwill pass out and till the space-between the barrel and tube or,

socket, andso equalize the pressure and pre- A check- 'Valv'e L2 is usually supported at or immediately above the upper end of the barrel, the support of such cheek-Valve being packed at Z2 a'nd provided with guides for the pumprod Mf/'lhc rod M extends into the barrel and connects with the plunger N, which has an upwardly-opening valve n. This plunger N, as shown in Fig. i, operates in the removable barrel L,being suitably packed therein, and has at its lower end the inletopening 9L', which tits a valve portion N on the upper end of the stand-valve when the plunger and stand-valve are in contact, so that in case of any breakage of the rods the plunger will fall into contact with the standing valve and the part N will close openingn and prevent any flowot' water down through the plunger. It would seem that the valves j', 1r, and L2 would prevent any backilow oifwater or oil; but when it is considered that leaks are in tentionally produced by filing or otherwise in the seats of valves used in the class of pumps to which myinvention relates the importance vided. with my limproved trap-valve; but I' prefer to use such trap-valve, as before stated.

It is preferred to use. the barrel and to lit "thestanding valve and plunger' therein -for convenience in removingtlnl standing valve,

and also t'o provide a eonstriujction whiehwill receive the wear of the plunger and ma)` be jeonveuiently removed when worn out for the substitution of a new barrel. It will be understood, however, that when desired the barrel may be omitted and the standing valve be supported and the plunger be operated direetly in the well-tubing without departing from some of t-hebroad features ot my invention. When so used. I adapt the plu-nger to be adjusted inioconneetion with Ilmsiandingthis end, as shown in Fig. S, I provide a threaded stein or tenen 0 on the lower end of the plunger, forming the lower end of such tenon O witha longitudinal slot 0. The upper end of the standing-valve block or support has a socket P, threaded to receive tap 0.

'lo prevent the tenen froinbeing forced by its longitudinal movement into socket P and destroy the threads as the plunger is operated, I provide a nut Q, having a detent or latch g, operating in a slot leading radially outward from its threaded bpre. This detent orlateh is'pivoted at its outerend in the said slot, and has its inner end-toothed or formed to correspond with the threadsof the nut. Theretore when turned up in its slot the latch will coincide with the threads of the nut, and the l latter maybe turned on the tenonO; but when turned on the end of such tenon and thelatch is brought to register with slot o the latch will fall so its uppertooth will rest in slot o and lock the nut from turning. Vhen; however,itis desired to lift the stat'ii'ing Valve, the plunger is vlowered to such partand the contact forces the detent into the slot, when the plunger may be turned to turn the tenon 0 through the nut into the standing-valve block, when the latter maybe withdrawn by elevating the plunger.

In: the construction shown inFig. l there is provided a shoulder at a: on the rod engaging a shoulder y in theY bai-Vitel, Aso that the eleva'- tion of such rod beyondits normal operatingpoint .sf'illclevate the barrel and its contents.

'iheoperation ol' such construction shown in Fig. l-will,it is believed, be fullyunderstood from the foregoing description.
