S PE CIEICATION
Background of the Invention Field of the Invention The present invention relates generally to systems for tLze filling, transport, and en~.ptyizlg of liquid containers More particularly, the invention concerns a novel, corrosion resistant liquid extraction apparatus that includes a novel plastic valve that can be removably connected to a liquid transport container. In turn, the valve can be interconnected with a specially conflg-cared, corrosion-resistant, plastic. coupler that operates the valve in a manner to enable fluid to be extracted from the container.
Discussion of the Prior Art The storage and transport of liquids and particularly floe storage and traaasport of hazardous liquids have long presented substantial problems. For many years liquids were stored and transported in throwaway type lnetal and plastic containers. Typically, such containers were provided witb. a threaded liquid outlet port, which, after the container was filled, was closed, by some type of threaded cap. The use of These types of containers was costly, ineffi-C1e11t aza.d often hazardous, paz~icularly When tlne containers were used to store az~d transpoz-~ potentially dangerous chemicals.
In recent years substantial effoz-ts Rave been made to develop new sys-terns to izmprove container and drum management capabilities, z~.~inimize user exposure to hazardous materials aald address emerging govenunental regulations. These effoz-ts leave resulted in the development of several dif ferent types of reusable systems for transferring liquid fonmulations fiom re-turnable closed dz-u.ms and containers. As a general z-ule, these systems to a greater, or lesser extent, Sllllplify dl'L1.111 elllptylllg, zninin ~.ize operator haz-ands, 1.111prOVe CleanlllleSS alnd eliminate costly waste izllnerent i.zi prior az-t disposable container systezns. One of the most advanced of such improved systen ~zs was developed by and is presently commercially available from. Mi-cro Matic, Izlc. of Noz~:Iuidge, Calif.
The Micro Matic system, whicln is described in U.S. Patent No.
5,901,747issued to tile presezlt inventor, basically comprises a two-paz-i:
sys-teIl1 that includes a coupler olaerated extractor valve which cazn be i.ntercoz~.-nected with a conventional dnun via existing tllr eaded cozlznections azld a ~co-operating coupler which cozlznects to tlne extr actor valve to allow dr uzn en 1p-tying Cllr ough the use of a remote puznpizzg system. The extz actor valve appa-rat-us includes a valve body and a down tube connected to the valve body, which extends to the bottom of th.e drum to permit the complete transfer of liquid from the dl~.nl.
Another Micro Matic prior aa.-t liquid transfer system is described in U.S. Patent No.S, 944,229 also issued to the present inventor. This invention concerns a novel, tamper-proof, safety valve system that includes a tamper evident valve closure cap that must be brolcen before liquid can be removed from the container.
The Micro Matic systems, while representing the best of the current state of the art liquid transfer systems, have certain drawbaclcs which are sought to be overcome by the system of the present invention More particu-larly, the metal valve and coupler assemblies of the Micro Matic systems are of a relatively complex design malting them somewhat difficult and costly fabricate. Purtl2er, i~n some respects these metal assemblies are not ~,~~ell suited for use with various types of hazardous and highly corrosive chemi-cats that are frequently stored and transported .
As will be better appreciated from the discussion that follows, unlike the prior art Micro Matic systems, the novel valve and coupler of the iln-proved system of the present invention are of an elegantly silnple design and are uniquely constl-ucted from a corrosive resistant plastic that is substan-tially impervious t0 I22oSt corrosive liquids. Additionally, the improved sys-texaa provides a customer unique, lcey type coupler-valve mating interface tlaat precludes removal of tlae dnun a contents by unautla.orized persons Summary of the Invention It is an object of tlae present invention to provide a novel liquid trans-fer system that includes a valve and coupler assembly of unique design for use in extracting hazardous fluids from a transport container. More particu-larly, it is an object of the invention to provide a liquid transfer system of the aforementioned character that includes a novel valve and coupler assembly that is of a simple design and is uniquely constructed from a corrosive resis-tant plastic that is substantially impervious to most corrosive liquids.
Alaother obj ect of tlae invention is to provide a system of the character described which improves container and drum management while at the same tilne significantly reducing the material and labor costs ilalaerent in the fabrication of tile prior a1-t liquid transfer systems.
Another object of the invention is to provide a liquid transfer systeln, which includes a novel plastic valve mechanism, which can be readily re-movably colmected to a container such as a lnetal or plastic drum, and a novel, plastic coupler lneclaanism that can be relnovably coupled with the plastic valve meehalaisnl for operating the valve mechanism. An importaaat aspect of tile liquid transfer systelll resides in the fact that the valve illecha-nislll is specially configured so that only a coupler of a special, plating con-flguration can be interconnected with the valve n lecllanislll. In this way, cou-peers alld valves can be custolll desiglled for individual users alld use of or tampering witll containers belonging to tJa.e individual user by users of 5111111ar SySte111S 1S positively prevented.
Another object of tile invention is to provide a fluid transfer systen l of the aforementioned character, which is ll.iglll.y reliable ill operation, leas a 1o1.1g useful life and is easy to use with a nlnlilllu111 am01u1t Of lllSt1'U.CtiOll be-illg required.
Another obj ect of tile invention. is to pr oxide a system of tile char acter described in the preceding paragraphs, which is inexpensive to produce alld requires lllillilllum maintenance.
Zll SLUlullary, the novel liquid transfer system of the present 111ve11t1011 includes a valve alld coupler assen lbly of unique design and a re1110te pu111p 111ea11S that Call be C01111eCtCd t0 the C0111~1C1' to extract hazardous fluids from a tTa11Sp01't COntalller. Tile plastic valve of the systelll comprises a valve body that is colulected t0 the container, W111C11 includes a coupler receiving portion and a hollow slcirt laortion, the hollow slcil-t pol-tion have a spiral groove fol-lned therein. An insert: leaving a central bore is sealably received within tile skirt pOrt1011 for rotational 1110ve111e11t by the coupler between a first valve closed position and a seGOnd valve open position. A down tube as-selllbly is colulected to tile valve body and includes a stele pol-tion that is sealably received within tile cell.t~al bore of the insert. The coupler of tile liquid transfer system, which ixlcludes a fluid outlet passageway in conunu-llication with tll.e fluid passageway of tile down tube assenlbly, call be conveniently, removably colulected to tile valve body for ilnpaa.-ting rotation to the insel-t. The plastic valve ful-ther includes a radially outwardly extending protuberance that is closely receivable within said spiral groove of tile slcil-t pol-tion of said valve body and the coupler receiving pol.-tion of the valve body is provided with circuluferentially spaced openings which re-ceive circulllferentially spaced blades provided on the coupler. Tile insert of the plastic valve, in tw.-11, includes upstanding fingers that are engagable by the spaced-apax-t blades when tile coupler is colmected to said valve body.
Ill ogle form of the invention, the coupler also includes a dowllwardly extending first sleeve, all upwardly extending second sleeve telescopically received within the first sleeve and biasing n leans for yieldably resisting telescopic nlovelnellt of the secolld sleeve into the first sleeve.

Descriptfon of tile Invention Referring to the drawings and particularly to ~'lgure 1, one i'on 1z of the apparatus is there shown intercormected with a conventional liquid transport container "C". Container "C" includes intercolmected top, boi.~tom arid side Walls "T", "B", alld "S" respectively that defna.e a liquid reservoir "12.".
Tlle apparatus of the 111ve11t10I1 here comprises a valve asselizbly 20 that IS
th.readably coluzected with top wall "T" of the container, a coupler assembly 22 that caxz be removably intercolmected with valve asselmbly 20 and a re-motely located pwmph~g means "f" for pulzzpiaig the liquid "L" from the transpol-t container. As best seen in figure 2, valve assembly 20 comprises a valve body 24 that is thr eadably connected to top wall "T" of container "C"
by conventional t1u eads 26 formed on the valve body. Valve body 24 ir~-eludes a 'tubular shaped slcil-t portion 28 that is provided with a plurality of circunlferentially spaced, calved grooves 30, the purpose of which will pres-entry be described. The top wall 24a of valve body 24 is provided with a plurality of circumferentially spaced ilzegularly shaped openhlgs 32 which her a are generally fan shaped.
Valve assembly 20 fin -then includes a generally cylindl-ically shaped insel~; 36 that is rotatably received within slcil-t po1-tion 28 of valve body 24.
In a lnamer presently to be described, insert 36 calz be lmoved by the coupler assembly 22 from a first valve closed position to a second valve open posi-Lion. As best seen i1-~ figure 6, insert 36 is provided with a central, generally cylindrically shaped bore 38 that telescopically receives upper portion 42a of stem 42 which forms a part of a down tube assembly generally designated by the numeral 44 (figure 2). Down tube assembly 44 also includes a flange portion 45 that is interconnected with slciz~t 28 of valve body 24 in the n zan-ner shown in figure 6. As indicated ll1 figure 6, step ~. 42 is con~a.ected to and extends both upwardly axed downwardly fro111 flange 46. The upper portion 42a of the stem, which cax~i.es aa.1 elaston leric O-ring43, is sealably received witlzi~.1 central bore 3~ of insert assembly 36, wlule the lower portion 42b ex-tends dowllwaxdly within reservoir "R". As indicated 11 flgw-e 2, the upper portion 42a of stern 42 is provided witli a plurality of circulnferentially spaced fluid passageways 46. As will presently be described, when the cou-pier assembly 22 is intercomzected witli the valve assembly and is rotated into the valve-open position, fluid passageways 46 will move into conununi-cation with. an outlet passageway fox~.ned in coupler assembly 22, which, in tul-n, conunun.i.cates with the pu~.mping 111ea11s "P" (figure 1).
Tumu~g particularly to figures 2 and 6, the novel coupler assembly of tl~.e present: invention can be seen to comprise an upper gripping portion 22a havrllg forger gripping segments 22b and a lower, downwardly exi;end-ing, generally lobular portion 22b. Affixed to po1-tion 22b of the coupler as-sembly are circun ~.ferentially spaced blade-lilce members 50 wlliclz engage circumferentially spaced srxrfaces 52 formed on a plurality of upstanding, finger-lilce portions 54 dial: comprise a pact of insert 36.
to As il~ldicated 111 flguxe 4, when the coupler assembly 2215111ated wltll tla.e valve assembly, the generally fan sllaped blades 50 will be received within the fall sl~laped opelaings 32 alld the edges thereof will engage walls 52 of fingers 54 upon rotation of the coupler. With this construction, rota-Lion of coupler asselubly 22 relative to valve assembly 24 will cause blades 50 to ilmpal-t rotation to insert 24 between tile first valve closed position shown ill figure 6 and the second valve open position shown in figw-e 11, In this regard, it is to be Noted that protuberances 40 of insert 36 are received witllill curved grooves or slots 30 so that, upon rotation of insert 36 by the coupler assembly 22, protuberances 40 will move along grooves 30 urgu1g downward na.ovelllent of insel-~ 36 frolll tile valve closed position s11ow11 in figure 6 to tile valve open position shown in figw-e 11 (see also figzues 7 and I2).
As indicated 11 figure 6, when the valve is ill tile closed position, a valve seat-ellgagillg sleeve 56 formed on coupler asselrlbly 22 will sealably engage a valve seat 58 fonrled on upper stelll pol~:ioll 42a. WLlen tile valve is in the valve open position illustrated in fgLUe 1 l, it is to be noted that outlet passageways 46 provided in stelll portion 42a call freely eonllllunicate with outlet passageway 60 Porn led in coupler asselllbly 22 and with the pulllpmg 111ea11S ~~1g11re 1). ACCOldingly, when tile valve is in the valve open pOS1t1011 S120WI2 112 l;lgure 11, upon urging of tl2e puznpil2g means, the liquid "L"
can be drawn froze the container "C" upwardly tl2rougl2 the dowla tube assembly u2 tile direction of tl2e arrow 61 in fzguxe 11, tl2rougl2 outlet passageways 46, into passageway 60 and then outwardly of the apparatus iI2 a direction to-ward tl2e ptllllp I22eaI2S "P". Pump Il2eaIlS "P" can con 2prise az2y suitable convnercially available puz22p of a character well understood by tl2ose slcilled in the art.
As illustrated in figures 6 al2d 11, coupler assembly 22 includes a downwardly extending sleeve 64 wl2ich telescopically receives an upwardly extending sleeve 66. Sleeve 66 teI-Inilzates in an end wall 66a that engages the top of valve seat 58. Disposed witl2in sleeves 64 al2d 66 is biasing means for yieldably resisting telescopic znoveznent of second sleeve 66 into first sleeve 64. This biasix2g n 2eans is here provided in tl2e foI-n2 of a conventional coil spI-in.g 68. As indicated 11 figure 11, as the coupler assembly is rotated il2to the valve open positioz2 there shown, spring 68 will be compressed iz2 a n 2aluzer tl2at will urge coupler 22 to retLUn to its upward, valve closed posi-tion.as showl2 in figure 6.
'VVitl2 tl2e consi:ruction described in the precediz~.g paragraphs, as the coupler assembly is rotated relative~to the valve asselubly, fr0112 the position ShOVVIl Ill figures 3 and 4 to the poS1t1011 Showll 111 figw-es 8 and 9, valve seat engaging sleeve 56 will move telescopically downwardly over tile upper pohtion 42a of stern 42 against tile urging of the biasing 111ea11S Or spzll~g 68.
When the coupler assembly reaches the position shown in figure 11, valve seat engaging sleeve 56 will have n ~.oved telescopically. downwardly zelative to stem portion 42a to a position where outlet passageways 46 are in fluid conununication with passageway 60 formed in coupler assembly 22. With tile apparatus ill the valve-open position, energization of puxllp "P" will, of course, cause fluid to be drawn from the container "C" outwardly of the ap-paratus itl tile direction toward pump "P". Rotation of coupler assembly 22 ul the opposite direction will, of course, cause tile apparatus to retul-11 to the valve closed position shown in figure 6 where sleeve 56 will sealably engage valve seat 58.
Turning to figures 13 arid 14, an alternate form of th.e apparatus of the invention is there shown. This fOrIl1 of the 111VeI1t1011 1S 5111111ar 111 most re-spects to that shown ixl figures 1 tllr-ough 12 and lilce nulllerals are used to identify like components. PIowever, in the embodiment of the invention shown in figures 13 and 14, the circun lferentially spaced openings 71.
formed in the valve body are of a slightly different configuration as are the blades 73 of the coupler asselllbly. lVlore paxi;icularly, as indicated in figure 13, blades 73' ai-e provided with a plurality of lcey-like shoulders 73a that axe closely received withila. the keyhole-lilce openings 71 provided in tlae valve asselubly. It is apparent tla.at, wlless tile coupler is provided witla. the cor-rectly confgured blades, the coupler calnot be used in conjunction with the valve body 24 of the character sl~.own in figure 13.
Turning to figures 15 and 16, still another foam of the apparatus of the ll1Ve11t1011 1S there 5110wn. Once again, this apparatus is sin lilac to that previ-ously descx-ibed and lilce nuna.erals are used to identify like components. In fh.e embodiment of the invention shown ilz f gores IS and 16, the circuxnfer-entially spaced openings 7S foamed in the valve assembly are of a different configuration 8"0111 that S110W11 ll1 figures 1 through 12, but axe similar to those shown in figua-es 13 and 14. Sin ~ilarly, the blades 77 fonued on the coupler assembly are of a different configuration from. those shown 11 fig-Lues 1 through 12. However, the blades h1 the apparatus shown h1 figures 15 alzd 1C~ are of similar configuration to those sla.own ili fig~.~res 13 and 14. Al-tb.ough this is the case, as indicated by tile arrow 79 in figcrxe IS, in tlxis lat-est e111bOd1111e11t Of the lllvellt1011, the coupler is rotated ilz a countereloclewise direction rather than a clockwise direction to move valve assembly from a valve closed position to a valve open position. Once again, with this llllpor-.
taut distinction, unless the coupler is provided with properly colzfigrired blades 77, the coupler camlot be used vVith the valve asseillbly laving the C011f~gLlrat1011 ShOWl1 In figure 15.
Refel-ring next to figur es 17 and 18, yet another form of tile appar atus of the invention is there shown. Again, this fonu of the apparatus is si.111iIar ll1 1110St respects to the apparatus previously described axed lxlce 11iu11eralS are used ll1 flgL7.l'eS 17 and 18 t0 identify life components. 1x1 tluS latest en1-bodixllent of the invention, it is to be noted that the operating blades 81 of tile coupler assembly and tile openings 83 provided ll1 tile valve assembly are once again of a different configuration. More particularly, as best seen in figure 17, blades 81 include a central radially outwardly exte11di11g protu-ber ance 81 a that is received within a notch-lilte opening 83 a that fonlls a pax-t of each of the blade receiving openings of the valve assembly.
It is clear frorll a study of flgrues 13 t111ough 18 that the coupler as-se111blies as well as the valve assemblies can be specially configtu-ed for par-ticular c~.~stormer so that only couplers belonging to that customer can be used to operate valves belonging to the customer.
It is to be understood that the configLUation of the blades and openings of the appa.ralus shown in the drawings is only exemplary, and that arty number of mating configurations of blades and openings can be provided to the customer.
is Havillg llow described the invelltion ill detail in accordance with the requireluents of tile j~atellt statutes, tllose skilled ll1 this art will leave no dif faculty 111 111ak711g changes and 1110d1f1.Gat1011S ll1 tile individual parts or their relative assembly ill order to sleet specific require111ents or conditions.
Such cllallges alld 111odifications lllay be made without depal-tin.g fro111 the scope axed spirit of the invention, as set fol-th in the follownlg clailus.

5,901,747issued to tile presezlt inventor, basically comprises a two-paz-i:
sys-teIl1 that includes a coupler olaerated extractor valve which cazn be i.ntercoz~.-nected with a conventional dnun via existing tllr eaded cozlznections azld a ~co-operating coupler which cozlznects to tlne extr actor valve to allow dr uzn en 1p-tying Cllr ough the use of a remote puznpizzg system. The extz actor valve appa-rat-us includes a valve body and a down tube connected to the valve body, which extends to the bottom of th.e drum to permit the complete transfer of liquid from the dl~.nl.
Another Micro Matic prior aa.-t liquid transfer system is described in U.S. Patent No.S, 944,229 also issued to the present inventor. This invention concerns a novel, tamper-proof, safety valve system that includes a tamper evident valve closure cap that must be brolcen before liquid can be removed from the container.
The Micro Matic systems, while representing the best of the current state of the art liquid transfer systems, have certain drawbaclcs which are sought to be overcome by the system of the present invention More particu-larly, the metal valve and coupler assemblies of the Micro Matic systems are of a relatively complex design malting them somewhat difficult and costly fabricate. Purtl2er, i~n some respects these metal assemblies are not ~,~~ell suited for use with various types of hazardous and highly corrosive chemi-cats that are frequently stored and transported .
As will be better appreciated from the discussion that follows, unlike the prior art Micro Matic systems, the novel valve and coupler of the iln-proved system of the present invention are of an elegantly silnple design and are uniquely constl-ucted from a corrosive resistant plastic that is substan-tially impervious t0 I22oSt corrosive liquids. Additionally, the improved sys-texaa provides a customer unique, lcey type coupler-valve mating interface tlaat precludes removal of tlae dnun a contents by unautla.orized persons Summary of the Invention It is an object of tlae present invention to provide a novel liquid trans-fer system that includes a valve and coupler assembly of unique design for use in extracting hazardous fluids from a transport container. More particu-larly, it is an object of the invention to provide a liquid transfer system of the aforementioned character that includes a novel valve and coupler assembly that is of a simple design and is uniquely constructed from a corrosive resis-tant plastic that is substantially impervious to most corrosive liquids.
Alaother obj ect of tlae invention is to provide a system of the character described which improves container and drum management while at the same tilne significantly reducing the material and labor costs ilalaerent in the fabrication of tile prior a1-t liquid transfer systems.
Another object of the invention is to provide a liquid transfer systeln, which includes a novel plastic valve mechanism, which can be readily re-movably colmected to a container such as a lnetal or plastic drum, and a novel, plastic coupler lneclaanism that can be relnovably coupled with the plastic valve meehalaisnl for operating the valve mechanism. An importaaat aspect of tile liquid transfer systelll resides in the fact that the valve illecha-nislll is specially configured so that only a coupler of a special, plating con-flguration can be interconnected with the valve n lecllanislll. In this way, cou-peers alld valves can be custolll desiglled for individual users alld use of or tampering witll containers belonging to tJa.e individual user by users of 5111111ar SySte111S 1S positively prevented.
Another object of tile invention is to provide a fluid transfer systen l of the aforementioned character, which is ll.iglll.y reliable ill operation, leas a 1o1.1g useful life and is easy to use with a nlnlilllu111 am01u1t Of lllSt1'U.CtiOll be-illg required.
Another obj ect of tile invention. is to pr oxide a system of tile char acter described in the preceding paragraphs, which is inexpensive to produce alld requires lllillilllum maintenance.
Zll SLUlullary, the novel liquid transfer system of the present 111ve11t1011 includes a valve alld coupler assen lbly of unique design and a re1110te pu111p 111ea11S that Call be C01111eCtCd t0 the C0111~1C1' to extract hazardous fluids from a tTa11Sp01't COntalller.

Descriptfon of tile Invention Referring to the drawings and particularly to ~'lgure 1, one i'on 1z of the apparatus is there shown intercormected with a conventional liquid transport container "C". Container "C" includes intercolmected top, boi.~tom arid side Walls "T", "B", alld "S" respectively that defna.e a liquid reservoir "12.".
Tlle apparatus of the 111ve11t10I1 here comprises a valve asselizbly 20 that IS
th.readably coluzected with top wall "T" of the container, a coupler assembly 22 that caxz be removably intercolmected with valve asselmbly 20 and a re-motely located pwmph~g means "f" for pulzzpiaig the liquid "L" from the transpol-t container. As best seen in figure 2, valve assembly 20 comprises a valve body 24 that is thr eadably connected to top wall "T" of container "C"
by conventional t1u eads 26 formed on the valve body. Valve body 24 ir~-eludes a 'tubular shaped slcil-t portion 28 that is provided with a plurality of circunlferentially spaced, calved grooves 30, the purpose of which will pres-entry be described. The top wall 24a of valve body 24 is provided with a plurality of circumferentially spaced ilzegularly shaped openhlgs 32 which her a are generally fan shaped.
Valve assembly 20 fin -then includes a generally cylindl-ically shaped insel~; 36 that is rotatably received within slcil-t po1-tion 28 of valve body 24.
In a lnamer presently to be described, insert 36 calz be lmoved by the coupler assembly 22 from a first valve closed position to a second valve open posi-Lion. As best seen i1-~ figure 6, insert 36 is provided with a central, generally cylindrically shaped bore 38 that telescopically receives upper portion 42a of stem 42 which forms a part of a down tube assembly generally designated by the numeral 44 (figure 2). Down tube assembly 44 also includes a flange portion 45 that is interconnected with slciz~t 28 of valve body 24 in the n zan-ner shown in figure 6. As indicated ll1 figure 6, step ~. 42 is con~a.ected to and extends both upwardly axed downwardly fro111 flange 46. The upper portion 42a of the stem, which cax~i.es aa.1 elaston leric O-ring43, is sealably received witlzi~.1 central bore 3~ of insert assembly 36, wlule the lower portion 42b ex-tends dowllwaxdly within reservoir "R". As indicated 11 flgw-e 2, the upper portion 42a of stern 42 is provided witli a plurality of circulnferentially spaced fluid passageways 46. As will presently be described, when the cou-pier assembly 22 is intercomzected witli the valve assembly and is rotated into the valve-open position, fluid passageways 46 will move into conununi-cation with. an outlet passageway fox~.ned in coupler assembly 22, which, in tul-n, conunun.i.cates with the pu~.mping 111ea11s "P" (figure 1).
Tumu~g particularly to figures 2 and 6, the novel coupler assembly of tl~.e present: invention can be seen to comprise an upper gripping portion 22a havrllg forger gripping segments 22b and a lower, downwardly exi;end-ing, generally lobular portion 22b. Affixed to po1-tion 22b of the coupler as-sembly are circun ~.ferentially spaced blade-lilce members 50 wlliclz engage circumferentially spaced srxrfaces 52 formed on a plurality of upstanding, finger-lilce portions 54 dial: comprise a pact of insert 36.
to As il~ldicated 111 flguxe 4, when the coupler assembly 2215111ated wltll tla.e valve assembly, the generally fan sllaped blades 50 will be received within the fall sl~laped opelaings 32 alld the edges thereof will engage walls 52 of fingers 54 upon rotation of the coupler. With this construction, rota-Lion of coupler asselubly 22 relative to valve assembly 24 will cause blades 50 to ilmpal-t rotation to insert 24 between tile first valve closed position shown ill figure 6 and the second valve open position shown in figw-e 11, In this regard, it is to be Noted that protuberances 40 of insert 36 are received witllill curved grooves or slots 30 so that, upon rotation of insert 36 by the coupler assembly 22, protuberances 40 will move along grooves 30 urgu1g downward na.ovelllent of insel-~ 36 frolll tile valve closed position s11ow11 in figure 6 to tile valve open position shown in figw-e 11 (see also figzues 7 and I2).
As indicated 11 figure 6, when the valve is ill tile closed position, a valve seat-ellgagillg sleeve 56 formed on coupler asselrlbly 22 will sealably engage a valve seat 58 fonrled on upper stelll pol~:ioll 42a. WLlen tile valve is in the valve open position illustrated in fgLUe 1 l, it is to be noted that outlet passageways 46 provided in stelll portion 42a call freely eonllllunicate with outlet passageway 60 Porn led in coupler asselllbly 22 and with the pulllpmg 111ea11S ~~1g11re 1). ACCOldingly, when tile valve is in the valve open pOS1t1011 S120WI2 112 l;lgure 11, upon urging of tl2e puznpil2g means, the liquid "L"
can be drawn froze the container "C" upwardly tl2rougl2 the dowla tube assembly u2 tile direction of tl2e arrow 61 in fzguxe 11, tl2rougl2 outlet passageways 46, into passageway 60 and then outwardly of the apparatus iI2 a direction to-ward tl2e ptllllp I22eaI2S "P". Pump Il2eaIlS "P" can con 2prise az2y suitable convnercially available puz22p of a character well understood by tl2ose slcilled in the art.
As illustrated in figures 6 al2d 11, coupler assembly 22 includes a downwardly extending sleeve 64 wl2ich telescopically receives an upwardly extending sleeve 66. Sleeve 66 teI-Inilzates in an end wall 66a that engages the top of valve seat 58. Disposed witl2in sleeves 64 al2d 66 is biasing means for yieldably resisting telescopic znoveznent of second sleeve 66 into first sleeve 64. This biasix2g n 2eans is here provided in tl2e foI-n2 of a conventional coil spI-in.g 68. As indicated 11 figure 11, as the coupler assembly is rotated il2to the valve open positioz2 there shown, spring 68 will be compressed iz2 a n 2aluzer tl2at will urge coupler 22 to retLUn to its upward, valve closed posi-tion.as showl2 in figure 6.
'VVitl2 tl2e consi:ruction described in the precediz~.g paragraphs, as the coupler assembly is rotated relative~to the valve asselubly, fr0112 the position ShOVVIl Ill figures 3 and 4 to the poS1t1011 Showll 111 figw-es 8 and 9, valve seat engaging sleeve 56 will move telescopically downwardly over tile upper pohtion 42a of stern 42 against tile urging of the biasing 111ea11S Or spzll~g 68.
When the coupler assembly reaches the position shown in figure 11, valve seat engaging sleeve 56 will have n ~.oved telescopically. downwardly zelative to stem portion 42a to a position where outlet passageways 46 are in fluid conununication with passageway 60 formed in coupler assembly 22. With tile apparatus ill the valve-open position, energization of puxllp "P" will, of course, cause fluid to be drawn from the container "C" outwardly of the ap-paratus itl tile direction toward pump "P". Rotation of coupler assembly 22 ul the opposite direction will, of course, cause tile apparatus to retul-11 to the valve closed position shown in figure 6 where sleeve 56 will sealably engage valve seat 58.
Turning to figures 13 arid 14, an alternate form of th.e apparatus of the invention is there shown. This fOrIl1 of the 111VeI1t1011 1S 5111111ar 111 most re-spects to that shown ixl figures 1 tllr-ough 12 and lilce nulllerals are used to identify like components. PIowever, in the embodiment of the invention shown in figures 13 and 14, the circun lferentially spaced openings 71.
formed in the valve body are of a slightly different configuration as are the blades 73 of the coupler asselllbly. lVlore paxi;icularly, as indicated in figure 13, blades 73' ai-e provided with a plurality of lcey-like shoulders 73a that axe closely received withila. the keyhole-lilce openings 71 provided in tlae valve asselubly. It is apparent tla.at, wlless tile coupler is provided witla. the cor-rectly confgured blades, the coupler calnot be used in conjunction with the valve body 24 of the character sl~.own in figure 13.
Turning to figures 15 and 16, still another foam of the apparatus of the ll1Ve11t1011 1S there 5110wn. Once again, this apparatus is sin lilac to that previ-ously descx-ibed and lilce nuna.erals are used to identify like components. In fh.e embodiment of the invention shown ilz f gores IS and 16, the circuxnfer-entially spaced openings 7S foamed in the valve assembly are of a different configuration 8"0111 that S110W11 ll1 figures 1 through 12, but axe similar to those shown in figua-es 13 and 14. Sin ~ilarly, the blades 77 fonued on the coupler assembly are of a different configuration from. those shown 11 fig-Lues 1 through 12. However, the blades h1 the apparatus shown h1 figures 15 alzd 1C~ are of similar configuration to those sla.own ili fig~.~res 13 and 14. Al-tb.ough this is the case, as indicated by tile arrow 79 in figcrxe IS, in tlxis lat-est e111bOd1111e11t Of the lllvellt1011, the coupler is rotated ilz a countereloclewise direction rather than a clockwise direction to move valve assembly from a valve closed position to a valve open position. Once again, with this llllpor-.
taut distinction, unless the coupler is provided with properly colzfigrired blades 77, the coupler camlot be used vVith the valve asseillbly laving the C011f~gLlrat1011 ShOWl1 In figure 15.
Refel-ring next to figur es 17 and 18, yet another form of tile appar atus of the invention is there shown. Again, this fonu of the apparatus is si.111iIar ll1 1110St respects to the apparatus previously described axed lxlce 11iu11eralS are used ll1 flgL7.l'eS 17 and 18 t0 identify life components. 1x1 tluS latest en1-bodixllent of the invention, it is to be noted that the operating blades 81 of tile coupler assembly and tile openings 83 provided ll1 tile valve assembly are once again of a different configuration. More particularly, as best seen in figure 17, blades 81 include a central radially outwardly exte11di11g protu-ber ance 81 a that is received within a notch-lilte opening 83 a that fonlls a pax-t of each of the blade receiving openings of the valve assembly.
It is clear frorll a study of flgrues 13 t111ough 18 that the coupler as-se111blies as well as the valve assemblies can be specially configtu-ed for par-ticular c~.~stormer so that only couplers belonging to that customer can be used to operate valves belonging to the customer.
It is to be understood that the configLUation of the blades and openings of the appa.ralus shown in the drawings is only exemplary, and that arty number of mating configurations of blades and openings can be provided to the customer.
is Havillg llow described the invelltion ill detail in accordance with the requireluents of tile j~atellt statutes, tllose skilled ll1 this art will leave no dif faculty 111 111ak711g changes and 1110d1f1.Gat1011S ll1 tile individual parts or their relative assembly ill order to sleet specific require111ents or conditions.
Such cllallges alld 111odifications lllay be made without depal-tin.g fro111 the scope axed spirit of the invention, as set fol-th in the follownlg clailus.
