1000601 In this first aspect of the present invention, there is a dispepsing spout 500 mountable to a liquid fetAng mtans, sucb as a dispensing nozzle , hose, container, or the like, to provide a delivery tiyKtcm ('or dclivcrinb liquid fn)m a liquid source, tiuclt as a portalblc l'ucl container 10, or the like, through a hose, sucls as a fuel ltose, garden hose, ot- the like. 7'lte dispensing spout 500 comprises a casing 120 having an inlet 139 to t=eeeive liquid fi=om the liquid source, sLteh ns the portable fitel container 10, and a diq,enc,-ing outlct 138, also referred to as the tLUttk tip opening, to dispense liquid to a de.stination, either a permanent or pot=table oontainer or receptaclc, or the like, such as a pottable fuel container, a fiiel tank, and so on. The inlet 139 and the dispensing outlet 138 Ln-e connected in fluid wrnmunication by a dispensing passageway 155.

JOtMMfi1 J'1'here is an openable and closable valve means, as indicated by the gcnL.~al refLxenec numeral 101, for p~.=rmitting and precluding, respectively, the dispensing of liquid fi=om the dispensing outlet 138 of the ciising I 10, The valve means 101 preferably comprist.'g a closLux: member 130 fur closing and opening the dispensing outlet 138, The closure -nember 130 is slidably retained with in the casing 120 lar movement between its open position and its closed position The valve means 101, s=poeifieally, the elosm=e member 130, is bia5csl closed by mcans ol' a coil spring, wpeeitically trunk spring 140, which is in ccmnpres.sion. The trunk spring 140, which is compressed in between the jet 150 and the clasure member 130, provide-: a I:eree that puslies the closure mo-ber 130, towards the tEunk tip 125. The Irunk tip 125 is tapesred to channet the tlow ol'liyuid to thc closure niember 130.

1000621 The closure membs~r 130 has an ='U"-ring 131 seated in a cooperating atuiular groove towards the iiont of the closure minbet-130. When the closure member 130 is in its closW pusition, as biased by the trutilt spring 140, the "O"-ring 131 seats against the inner annular sutface of the tip of 125 of the casing 120, which is the dispensing outlet 138 of the casing 120. The dispetsing opening 138 is soalcd ag the force ol'the trunk spring 140 eampi=esses the "O"-ring 131 between the closure snember 130 atLd the tt=tudc tip 125 interior, thereby providing an airtight leak-proof seal (see Figures 4, 5, 19 and 24).

(00063] Whcn the closut=e member 130 is in its open position, the "O"-ring 131 is saparated in space relation from the inner annular surfaee of the tip 125 of the casing 120, thuu pcrmitting liquid flow between the closure member 130 and the dispensing outlet 138.

[00064] '1'hc dispensing spout 500 fiuther compiises a slider nsscmbly 200 mountod in sliding relation arottnd the casing 120.

7'he slider aiBsembly 200 is movable between a forward pcnition, as c:an bc best scc.n in tigun.:Y 1, 2A, 21:3, 3, 4, 18 and 1 ), and a rearward position, as can be best seen in figwt..~ 20,21 and 22. '1'he tbrward position and the rearward position of the slider assembly 200 conresponds to the closud position and tlm open position, respectively, of the closure member 130. Accordingly, in order to open the valve means gencrall.y refcrred to by 101, the slider assembly 200 is moved rearwardly, in an indirect manner, as will be discu.5ticd in gi=e:ater dL;tail sub.sr,quently.

100651 The disnensina srout 500 also comprises a seu,sptaclo enpaQinR tt=iaacr mcan5 acucrallv refctled to by 301 nnerativelv mounted on the casing I 10. More speci(ically, the receptacle engaging trigger means 301 cotuprises a trigger assembly 300 disposed in sliding relation on 4tc slider assembly 200. The receptacle engaging trigger means 301 includes an upper hook 325 and a lower hook 328 for engaging thc inlct rim of a Coiltaiiier 10. Eaclt of tlte upper ltook 325 and the lower ho4k 328 is cotuiected to, and preferably fomicd as an integrally molded part ofthereceptacle engaging trigger means 301 (I'm thinking this is only the red part).

1000661 The receptacle engaging trigger means 301, and more specitically the triggcr assembly 300, are movable along the casing l 10 between a valve-open position, as can be bcst tic:c.=n in ligurc:s21, and a valve-ologc:d positirm, as can be best sec,~n in figuTx's19. The trigger asseinbly 300 is bia-nd to the forward valvc-closcd position by mcans of a trigger return spring 330 inountcxl in sttbstantiall,y sutrowtding relation on a triggcr spring guidc:
shaft 321 that extends reatwardly froen the upper hook 325, and also seats in a trigger staring guide 230 on the ylider assembly 200.

1000671 In the valve-closed position of the iriggt,-i- assembly 300, lhe closure mcRnbcr 130 is bih3cd closed by the trLUik spring 140 auch that the "U"-ring 131 seats against the inner annular sitrface of the tip of 125 of ihe casing 120. Accordingly, the valve means 101 is closed. In the valvc-opcn position of the trigger assembly 300, the closLU=c member 130 is tnoved to its open position agiiiiist tiie biasing of the trunk spring 140 sLx;h that the'=b'=-ring 131 disposed in space relatiort frnm the inner nnmilar surface that defines the dispensing autlct 138, at the tip 125 of the casing 120. Accordingly, the valvc mcans 101 is vpc:tt, and liquid can flow through the easing 120 and out the dispensing outlct 138.

[00068] The dispensing spout 500 accordin$ to tlte present invention further comprises linkage means 315 operatively conneeting the rcceptacle engaging trig6pear tneans 301 and the valve meana 101. The linkage means generaIly rcferred by 315 has an cnablcd configuration, as cun be best seen in rgurcK 18 and 20, and a disabled configuration, as can bc hest seen in figurc 23. In its emebied conftguration, the n.~c:eptacle engaging trigger means 301 and the valve means 101 are operatively connected such that movement of the receptacle engnging trigger rneans 301 from the valve-closed pUsition to the valve-open position cau.Ka.a the valve means 10 1 tu open, More specitically, as oan be best seen in figunes 18 and 20 the linkage mcans 315 transmits a rearwmdly directed foroe itc,m the receptacle engaging trigger means 301, sPecifically the upper hook 325 and the lower hook 328 and the trigger assembly 300, to the linkage mcan.4 315, as will be discussed in greater detail subsequently.

[00069] In the disabled configuraticm, the valve means 101 is closed such that fluid cannot bc dispensed frcun the dispensing outlet of the casing 110. Pttrther, the vnlve nii;ana 101 is preeluded from being re-opc7ied by movement of the reeeptac;lc engaging trigger means 301 uutil the linkage means 315 is reset to its enabled configuration.

[00070] More Kpecifically, the linkage means 315 comprises a lirst linkage member 344 and a second linl:age member 260 cotuwctcd together in angularly vatiabic relation at a linkaga elbow 750, so as togetl-er to be movable 1-mtween the enabled mtfiguratitm, as can be best seen in tigures 18 and 20, and the disabled vanfigurati(m as can be best sa.~n in ftgure 23. The first linkage manber 340 and the sr.wnd linkage member 260 each have two parallel identical arnis, for the sake of redundancy and strength.

[000711 In the prefeired embodiment, as illustrated, the first linkage member 340 and the second linkage ntember 260 connected togcther in pivotal relation at the linkage elbow 750. A"C"-shaped axis clasp 342 disposed at the back and of each of the arms of the first linkage member 340 rcecives and retains in pivntal relation a slider linkage axis shaft 262 disposed that the front end of ahe second linkage member 260.

[001172] '1'ho first linkage member 340 is operativcly maunta3 on the reoeptaele engaging tt'igger meanv 301 ttnd the sc.ccmd linkage member 260 is operatively mounted <m the slider asaermhly.
Accordingly, Qic Gryt lintkage member 34() may be referred to as the trigger linkage member and the seccmd liiilcage member 260 may be neferred to as the slider linkage member 260. '1'he trigger linkage member 340 has a trigger li,nkage nxis shaft 341 disposed at its front end, which is received and retained in pivoting relation within a trigger linkage axia kh.aft clasp 323 that is integrally formed on the triggcr assembly 300.

[00073] The slider linkage member 260 has a"C "-shaped axis cla%T 261 dLsposed at the hack end of each of the arms of the silder linkage member 260, which is reeeives and retains in pivoting rclation a slider linkage axis shaft 226 that is integrally furmed on the slider assembly 2U0. When aswmblad together, the trigger l.in3cage member 340 and the slider linkagc member 260 are spring biased to the enabled configuration by means of a reed spring 343 c.mneoted to the tligger linkage member 340.
Preferably, the recd spring 343 is integrally formnd aa patt of the ttigger linkage member 340.

1000741 '1'he dispensing spout 500 furlhcr cnmprises a deactivation means 156 for cllanging the linkage meana 315 from the eiiabled conliguration to the disabled con6guration. 'l'he deactivation meatis 156 includos a venturi means 157 disposed within the casing 120. More specifically, the venture tncana ccxnpriscs a venturi that is disposed at the tip 151 of the jet 150. As liquid leaves thu jet tip 151, which is an integral part of the ventuti. it will expand bccAming turbulent. '1'he expmisum and the turbulence of the itow will cause the liquid to collect and ntix with air and that air will exit the dispensing spout 500 with Ihc liquid being dispct>yc:d thrnugh the dispensing outlet 138. '1'he liquid tlowing through the trunk body 120 will create a negative pressure within the trunk body 120 which will continnally draws air into the trtuilc body 120 through airway 127 as the liquid is flowing. This negative pte.v.vure is the forae whioh is used to chengc thc linkagc means 315 fitrm its cnablcd cor>figuration to it.c disabled conflguration, as will be cacplaincd in greater detail subsequently.

1000751 The deactivatitm means 156 also c,ompt'ises an air conduit 240 having an air inlet 241 at a front cnd thereof and an air outlet 227, The air conduit 240 is in fluid communication with the dispensing pas-saseway 155, to interact with the venturi means 157. More specifically, thc air conduit 240 is in fluid eommunieation with the dispensing passaeeway 155 via an air hole 228 in the slider assembly 200 and an expandable and netraetable chamber 242 bLxw .sn Ihe air conduit 240 and the air hole 228.
'1'he expandable and retractable cbamber 242 axnpiiyLs a eylinder 220 and piston 221 moveable within the cylinder 220. The piston 221 engages the cylinder 220 in substanti:dly scaled relation due to an "U"-ring 222. There is also a spring means, specifically a coil spring 223, to bias the piston 221 to an extended position. Piston arms 224 extend latt.n'ally oatwardly froni opposite sides of tlte piyton 221, -c> as to be able to engage the linkage elbows 750 on each side of the linkagc mcans 315.

_ g ~

[00076] The air conduit 240 is in tluid communication with the dispensing pa,rsageway 155, as dcu:r-ibed above, to permit the dt-awing of air into the dispen+ting passageway 155 through the air inlet 241 whcn the air pressurc is reduced by the venturi tneans 157, but inhibiting Lhe flow of air inta thc di5l,cnsing passageway 155 when the liquid lcvcl of dispensed liquid reaches the air inlet 241 and blocks access of nir into the air inlet 241. When thG airflow into the dispcasing passageway 155 is inhibited, the air pressure within the cylinder 220 prodtx;cs a downwatd force on the piston 221, thus lowering the piston 221 from a raised pusition, as smn in figures 19, 20 and 21, to a lowered position, as seen in figures 22 nnd 23. As the piston 221 moves downwardly, the piston anns 224 push on the trigger linkage member 340 attd the slide<= linkage tnember 260 of the linkage means 315 at the linkage elbow 750. '1'ha trigger linkage member 340 and the slider linkage member 260 go from their enabled configuration, past an over-the-center point, and essentially fall lo their disabled onrtfiguration. ln thia manner, the deactivation ntean.s 156 has caust.-d thc linkege mettns 315 to change to the disabled cxsnrguraLinn, which in turn causes the valve moans 101 to close, thus precluding the delivery of liquid from the dispensing outlet 138 of the ensittg 110.

1000771 In a motr: gerttral scntic, it can readily be seen that the deactivation means 156 is for changing the linkage ntcans 315 from the enabled txmtiguratitm to the disabled cortlil;uration, in response to dctecting the proximity of dispensed liqnid in a rea;ptaele, to ther-eby allow the valve means 101 lo close, thus prcxlutling the delivery of liquid IiYxn the dis'pensing outlet 138 of the casing 110.

[0078] 'I'here is also an indication meaas operatively mounted on thc: casing 120 and comprising a dial indicator 420 with a display 421 as seen in the covers window 411 of the cover body 410. The dial indicator 420 is pivotnlly mountcd within the interior. A huh means with in the cover body 410 provides the dial indicator 420 with a pivot point 412 where the axis shafts 422 on the dial indicator rib 423 is Icx;atcd. When the dispensing spout is in the closed yt:uing, thc dinl indicator stcp follower 424 en thc dial indicator rib 423 will be in eontact with the dial indicator step 350 which in tum will oriettt the dial indicator 420 at an angle that aligns the cloxc:d tcwt on the dial indicator display 421 with the u,vc.-rs window 411 so that it can be seen.
Similarly, the step follower 424, the dial indicator rib 423 atid ilial indicator step 350 react to the relati.ve p>sititining of the parts of the dispensing spout to indicxte Q-c deaetivaticon and start orientatims as well.

[00079] As shown in the drawin,.*s, there is a dispensing sPout, generally refcttrcxl to by the numera150U, mountable to a liquid fcoding means for delivering liquid fi-cna a container or a hose. In Figure 2 and 4, the liquid teeding tneans is a nocr.le 20 wheretts in Figure 1, it is the Ilrn-aded delivery neck 43 of a gas container 10.

1000801 (Tencrally the dispensing spout wmpriscs a delivery truuk body 120 krrmed with a dispensing pa.ssagewa,y 1551eading to a dispensing opening 138 for delivery of the liquid- Withitl the delivery Irtutk body 120, a ventuYi tncans generally referreci to by 157 exists to redttoe the pressure within the dispensing passageway ax liquid flows through it during use because, after flowing through the smaller pa.ssageway of the jet 150, the liquid flows through tlw larger passageway of the delivery trunk hody 120, thereby rt:tiucing pressure. Briefly, the ventttri mearra is coupled with a control rneans, which includer, a deactivation rneans.
The de-aetivatirm rneans including an ait'way 127 with an air crpctting 241.
The air conduit 127 is in coimntrnicatiexr with the dispensing passageway of thc trunks body 120 to permit the drawing of air ittto thc t3ispOn4inb passageway through the air opening whcn pressure is r-educed as aforesaid dtnYrtiR use. The air opening 241 is disposed on the di%pensing spout ta tnark a tlrretihuld level whLrahy when liquid in the receptacle rises up to reacli the level where the: air uptating exists, further air flow into the dispensing passagewtty is thereby cut off. The deactivation mcans then responds to shut off (stop) the dispensing opening. More parlicularly, thc de-:tclivation means has a elostire member 130, which is caused to move in the direction of tIow within the delivery trunk to shut atl'the dispensing opening upuri whcrt llx:
air ope.-rting is blocked off$'oin air during uso, due to the change in pressure. By having the clcxrurc member move to shtttoff the dispensing ciponing in the direction of flow, space is saved so that the closttrc mrarrber can bc casily disposed within ihr;
sp[xtt. 'rhis will be more particularly t~?Cplained by the detailed description of the prefetred embodiment, which ht:reby follows.

[00(181] Genet~ally, the prefCrrcd r.mbodimcnl is a dispensing spout whielt has three furu:tional et:ttinl,.nr, namely I)'ci(md' where the dispensing spout is not insnticxl into thhe opening of the receptaale and the delivery passageway in the dispensing spout is closed, 2) 'open or start' where the dispensing spout is mounted onto the receptacle alid liqtud can be dolivcTcxl liom the sotwce, be it a delivery hose or a container; and 3) 'tusut and closed' wherein the delivery spout is mounted onto the receptacle fot' delivery of liquid but the contrcml means is aetivated, by reason of the neoeptacle being filled to a threshold level on the spout dispenstr causing the dispensing spout. to close off fltrther liquid delivery.

1000821 Respecting thosc three settings, there is an indieation tneart:t txxnprising a dial indicator 420 with a display 421 as soen in the covers window 411 of the cover body 410. The dial iatdicator 420 is pivotally motutted within the interior. A hub means with in the cover body 410 provides the dial indicator 420 with a pivot point 412 where the axis shafts 422 on the dial iruiioator rib 423 is lcx:ated. Whcn the dispensing spout is in the closed setting, the dial indicator step folluwcar 424 on the dial indicator rib 423 will be in u>ntact with the dial indicator step 350 whieh in turn will orient the dial indicator 420 at an angle that alips the clusud tr:xt on the dial indicatur display 421 wiYlt thu mvers window 411 so that it can be seen. 3imilarly, !he step follower 424, the dial indicator rib 423 and dial indicator step 350 react to the relativc positioning of the parts of the dispensing ccpnttt to indicate the de-activatirtin and start orientations as well, [00053] As ahown, in the drawings, the prefetred embodiment illustrated is a dispensing spout that can be c;a.sily securcd as a delivet'y systctit for a liquid sottrce, whether it be a htisc, a oontainer or a ncrrlle using statxiard threading or other appropriate meanis. ln Figttres I and 2, there is shown the dtspmsing spont, generally rcfcrred to by the ntuncral 500 ntotutted to, tvspoutively a standard-type gas cxxitainer 10 and a gas delivery txur.tc 20 with a fuel line 23. The dislaensitg spout 5Ut) is euu,ntmted, in both cases, by thnnded couplers, referred to in the drawings ax 43 and 22, re.spectivaly. As will be readily apparent, thc coupling meane is standard and its desigtt will depend (m the application and device to whiclt the dispensing spout will be mounted, As wcll, although this spec,tificatiml is being described in conjunction with a gas deltivery, nevz]e 20 and a paa container 10, it could be rnotn-tcxl ta nny type of liquid yource which is to be poured or delivered, be it a different tyl-m of delliverysystent such as a hose or tube, or a diiTcrent type of liquid other than gas.

[110084] Whan the dispen.ging spaut 500, is in the ckmc:d position, liquid fucl is prevented fivni flowing through it and out oP
the dispensing opening. 7 hc: system is ac:aled. It is the trunk body 120 which acts to seal the dispensing spout. The ttUmk body 120 itself utilir.m three openings, which are unsealed or sealed to enable the 1'unctioning ot' ihe liquid delivery or non-delivLry, One of thcsc threc openings is the ttunk baRes opening 139, another of these three opcnings is truak tips opening 138 and thc third of these tht ee openings is the trunk bodies nirway 127 located on the side uf the trunk body 120.

[00085] The trunk bases opening 139 is sealed it'urn the atmosphcre by the screw cap 190, whiclr is threaded on to the cpttltling means of the liquid sottree, be it a nozzle ur gas container or otlterwiaa;, The scrcw cap 190 sandwiches the trunk ba:to 126 and the jet base 152, as tlx case mey be in the drawiugs, against cither the norzic cxiupler's leading edge 25 or the gas ontttaittex's inlet rint 42 providing an uittight leakpnooFseaI 1) for the nozzlc: as between the nozzle cuuplar 22, jet 150 and tctmk base 126;
or TI) for the gas container, the gas container coupling mcans 43, jet 150 and trunk base 126.

[00086] '1'he truttk tips opening 138 is sealed when the trunk eor-a 130 is urged againat the interior of opening 138 (sec Figt,res 19 &c 24). The trtuilc oore 130, dtuing thc opcration of the dispensing s-pout 500, is caused to slide axiall._y within the interior to the trunk body 120, to tnovC between a scaled position (as is the easn: in the stop and de-acttvatlon ,etttngs) where it is sc:atcd against tlie irttcrior of opening 118 (see Figures 19 & 24) and an open position (as in the case where opeui setting) where it is unsoe ted away frum the rim of the opening 138 (see P'igttre 21). As should he apparCnt, there is no (lowthrottgli of liquid li-um the source when the trunk tips opcning 138 is sealed. In the prcfi.,rred embodiment, the Trunks tip 125 is tapered at its forward cnd to cause incrua.sed constriction of tlte rim uf the trtrttk tips opening 138 against the liont end of thc: trunk core 130 as the normal biasing fcm:e of the spring 140 asserts itselt; there, being a trunlc cores o-ring 131 which seeure.s the seal as airtight and Ieakproof. The trunk tips opening 138 is the operratfvc opening, which must bc shut or opened to prevent ur pcrmit flow as the eamo may be, lf the trunk tips opening 138 is opcn, liquid flow is paSsible.
Ii'the ttutilc tips oponing 138 is closed, no flow is possible.

1000871 The trunk btxlic:s nirwny 127 is to he ttnderatood functionally with the air passagetvnys which surround its two ends.
This airway 127 funetionally provides a passageway for air into the trunk haiy to merge with liquid passing thtvugh the venturi 157 scc iigures 19,21 and 24 as it is being dispensed thtvugh the dispensinb %rc+ut 500.

(OtNNiB] But when air supply can no longer be drawn through the ttvnk htxlias airway, such as would bc the case if the level af liquid fill in the reoeptaclc reaches the threshold level of air channel inlet 241 of the sectioncx] slider 210 (as will be deyc:ribW
latcr), an increased vacuum p1-essure situation occurs within the dispensing spout to caitse the trutilcs eore 130 to reseat against the interior of the opening 13R to shttt off the dispensation of liquid. This will be described in t'urther detail later.

[000811 Sufltice it to dis~:luYC: at this portion of the description, however, that there is a chantber asrcat<xi aa between o-ring 121 and o-ring 122 existing between the exterior uf trunk bodies 120 and the intet'icn- of the glidet' body 280. The slider body 2$0 has an cylinders bottom air hole 228 which fluidly communicates through the chttinber of the piston cylinder 220 with the cylindet-i air inlct 227. Cylinders air inlet 227 opnns into air channe1240 which et+tends to air channel inltA 241, Dtiring usc, however, as will he described latt:r, air ic drawn into the chatnlier of the lrunk body 120 in the opposite direction of the fluid ll(nv, meaning that nir enters the erystem through air inlet 24 t, travels thrcxtb=h air ehannel 240 and air inlet 227 and then throug,h the chambcr of the piston cylinder 220 to cacit tlurough air trole 228, thcn through Lhe chainber defined by the n-rings 121 and 122 and into the trunk bcxiy 120 through crpening 127.

(00090] When opening the dispensing spout 500, the tip 201 should be placed inside a gas rcocptacle inlet 41 wliere either the triggors uppen ccx)k 325 or the triggers lower hook 328 is rested on the gas containcx inlet rim 42 (see rigmx; 16). Once in place and properly align~. the user will either apply pressure down the length of the nozzle 20 or press down on the gas exmtainer with a fotre along the center line of the auto closure auto shut off spout 500, This force will be transfen-ed to the trigget=
lnxiies hooks (325 & 328, delliending on the figure) which an: integrally molded into Ihc trigger body 320, The spouts triggc:r assentbly 30() will then convey thnt f'orce to the spouts slider assembly 200 via the connecting linkages causing the spouts slider assembly 200 to slide axially along the spouts trunk assembl,y 100 towards the trtmks base 126 (see the change in poeition as between Figures 19 and 21). The forcc lransfetred to the spouts slider assembly 200 by the spouts trigger assembly 300 will have;nen fiuihc:r transt:fenred to the tntttks oote 130 via the trunk cores tip ridge 133 which is in contact with the exit grate 250 of the slider bodies 280 (Suel1gures 19, 21 and 24). That force, in turn, will tratider through the trnmks ccre 130 to compress the trtuiks spring 140, which was also being compressed as Lhe tnuilcs c.orc 130 slid along the nuerior of the trtuik body 120, corresponding to movement of the spotrts slider assembly 200. (see eomparison of rigttres 19 and 21). Resuliittg from this, the spouts slider assembly 200 will be movui to unseat thc trunks eoreso crring 131 of the trunks tip 125 from Lhe rim area of the opening. Liquid is allowed to flow from the anuroe through the jet 150, down the length of the trunk body 120 around the trunks eore 130, out the trtutkq tip 125, into the interior of the slider body 280 and past the exit grate 250 out of the dispensing spout.

[000~11 ] As the dispensing spout 500 was c:hanged to the open position, the display 421 of the dial indicator 420 was moved from indicating "eloscd" Lo "npen" as appears in the covers window 411 so that tlie dial indicators step follower 424 on the dial indicators rib 423 ra:sts on the trunks dial indicator step 124 (.,;cc Figurc 22). More partic.ularly describing the movement from the elosed position tcr the open position, a; the spouts trigger assemhly 300 and the spouts slider assembly 200 were moved axially along the spouts ttvnk assembly 100 kiwards the tnmks base 126, thc spouts covc.-r assembly 400 (attached t) the spouts triggcr assembly 300) algu was carried. As all three of these assetnbl.ies 200, 300 and 400 moved together, the dial indicators step follower 424 eeme into contact with the tru-ik-s dial indieator r,tep 124. In result, thu dial indicator step Roilower 424 wila have then ridden up onto the trurtks dial indicator step 124, rotating the dial indicator 420 clockwise about the dial indicators pivot point 412. So it is that the cuitet= area of the dial indicator display 421, which reads'start' thcn:upon appears in the cavera window 411 to he seen by the user.

[000921 '1'hc design of the dispensing spout 500 takes adventage of the tluid dynatnies within the spotns trunk assembly 100, which has been configured to utilizc vcnturi principles. As khe liquid lcavcs the jets tip 151, it will expand becoming turbulent.
'1'he expansioti and t}w turbulence of the liquid tlow will cause thc liqttid to eollect and mix with air (entLxing the system through air inlet opening 241 and following tlte roule previously described) within tlx; trunk body 120 so that tlie air will exit tlxe dispensing spout witb the Gquid, As the dispensittg spuut was nniented into the 'open' poaition, the airway was ope:nod up between the exterior of the dispensing spout and the interior af the trunk body 120 to allow airflow dircctl,y into the trunk bcKly 120. Moving into thc 'open' po,cition from the 'cloaed' position, the spouts slider assembly 200 moved along the trunk hody and the liole in the bottom of the piston o,ylinder 228 created an aiYway into the ttZulk bcxliCs 120. This aligrunerr,t omables the air to eiitering the spouts air inlet opening 241, llowing down the slidera air cAmwel 240, into tl-ie piatcaLa cylincler 220, dovvn through the cylinders bottorn air hole 228, into the cavity bctween the trunks lower o-rinKs 228, and thcn througlt Ihe trunk bodaes airway 127 into the tnutk bodies 120 interior (see Figure 21). The air intreduced into the trunk body will enter behind the jets tip 151 into the jets air cavity 154 where this eonfiguration helps prevent liquid frnm going directly intn the trunk bodics.w airway 127. TJtilizing venturi principles, the liquid flowing through the trunk body 120 creates a negative pressure within Lhe tnmk body 120, and it is this nebativc pressure which eontinnally draws air into the trunk bcxly 120 ax the liquid is flowing.
[000931 To tuni oft'the IIuw of thc: dispcnying spout and return the indicator to the 'close' pmitic-n, the user need only rcmerve the spouts tip 201 from the opening of tlle gas receptacle 40 (see Figure 16).
Doing this removcs the tiorce assvrtaxi against the triggers lower hook, allowing ttic trunk spring 140 to reassert its normal biased position to return the Irunk core 130 to the oltxaed oriuntatiun (scc Figure 19). Iteturning to that position, the force of the trunk spring will press the trunk trc 130 in the area of the trunk cores crring 131 against lhc intorior of the opening 138, tvsulting in a leak-pYWceal. It will be apparent that the ttvnk wre 130 ac;ts a.s a valve means.

[0Mt94) In the preferrui eanbodiment, the tnuil:s body 130 movc:,4 along the axis of the direwtian of flow and this ureatcs an econainy of spaee, alluwinb the xpout, to be made of an more uuni.pact dimension than if the valve means had to nwvc 1tcTcndicular to th.e axis o1'the direction of flow. There are advantages aehic.-ved by this prefered cexifiguration, but it is also possible to achievc closing by creatving a valve means that clus+.ss the dispensing opening by moving in a d'u=ectiun pcipendicular or different to the axis of the direction of flow.

]00093] However, it will also be &-sired that the user will be sable to rely upon this dispensing spout to automatically shut off the flow ot' liquid upon the gas receptacle 40 reaehing a filled up capacity.
'I'his automatic shutoff iw what can be tctmed as the deactivation condition position. In this regard, the filiiA up capacity would be reached uptm Lhe level of the liquid deposited in the reoeptacle 40 rcac;hing a threshold marking on the dispensing spout, namely where tha ohannel inlet 241 is disposed. '11tis is where no further air can bc drawn into the llow system and the pressure of the system will be altered causing a mechanical reaction of the part, which will automatically shut off the flow of liquid or deactivate the spout (sw Ligurc 23 and 24).

[001196] As the air ehannel4 inlet tip 241 is covered by the rising liquid in the gas receptaulc 40, air would no longer be able to enter the air channcls inlet tip 241 and that would create a decrease in presstu-e within the interior air passageways and cavities, n.ameiy the air channvl240, pislon cycler 220, the cavity between the trunks lower o-rings 128, and trunk body 120.
As this dcx:rease in presstue ecmtinues, the pistou 221 will be drawn down (scc Figure 22 arx123). The downward moLion of the piston 221 will in turn act on the slider linkage 260 and the trigger linkage 340 via the piston arms 224, which will be pushing the litzkago elbow 750 downwardly (see Figtn-c 22).

[00097] As previously describect thc fnrce applied to the spouts trigger assembly 300 rtceded to open thc dispensing spout was canvcycd through the trigger iinkage 340 and was transferned to the spouts slidar assenzbly 200 via the tilider linklage 260 causing the spouts uiggcx assembly 300 and the spouts slider assembly 200 to move together as they slid axially along the spouts trunk assembly 100 towards the tnmks base 126. The auto shutoff feature of the preferred einlxalimcnt works by relieving the spouts slider asseinbly 200 of the farcx heing transferred to it by the spouts triggc.-r assccmbly 300. As the liquid in the gas rcccptaclc 40 reeches the threshold level, it will covcr the xir channels inlet tip 241 causing the vaouum pressure in the air canduit to increase which will pull thc pi.stoti 221 down disengaging the rigid uamcx:ticxn hetween thc spout.R ttigger assernbly 300 and ttx: spouts slider assembly 200 (see Figure 23).

[00098] The piston arYns 224 cxtending fortn thC side uf the piston 221 will push drnvn oti the lihkagc: cIbow 750 which will rotate the trigger litilcago 340 clockwisc about trigger Iinkage axis 341 and rotating slider linkage 260 counter ckx:kwise about slider linkage axis shaft 226 until the force conveyed between the linkages 340 and 26U is rclieved (see Figttre 23). In the present invention, tlie trigger linkage 340 will have t-otated ciuckwivc about trigger linkagc: axis 341 to be pointing hclrnv the horizontal and the slider linkage 260 will havc rolatad counter clockwise about slider linkage axis sltal122fi to be then directcxi downwardly (acc Figurc 23).

[000991 Thc disengagcmcmt of the ridged conneotion bctwmn the linkages 340 and 260 pceYnits the trunk sl,ring to reassert tu its normal biased disposition and push the spouts slider assernbly 200 to its closed position, sealing the dispensing apc.-ning at the ttunk tips 138. In contrast, the spouts trigger assembly 300 remains in placm (aec ligun: 23 and 24), As well, as the apouts slider assembly 200 slidea axially aloug the trunk bucly 120 Luwards its closed position, the piston cylindetw bcnwm air hole 228 will niuve; uut uf cvmmuniealiun with the cavity between the trunks lowcr n-ri~tgs 128 to Inttlt'rupL thc airway cimated when tlte auto shut off spout had been opened, As the de-aetivation disposition is occwring, the piston cylindars bottom air hole 228 will nlove axially along tltc trunk body 120 from the cavity between the trunks lower v-rings 128 to the cavity hetwee<i the trunks upper o-rings 129. The cavity bctwccn the tiunks upper o-rings 129 is tirrmed by the trunk,a o-ting at the tip 123 and the trunks middle o-ring 122, which an: sandwiched inbetween the trunk bodies 120 exterior and the clider bodies 280 intaior_ [0001001 As thc flow of liquid stops, the ventuti vacuum pressutvprcxluctx7 by the flowing liquid will also stop, creuting an absnnue ui' thc decreased prassure that had drawn the pistmi 221 downwardly. Wh t this decreasing presstu-e nlrcx;t is lost, the spring 223 will reas,xxt its shape and push the piston upwardly within the piston cylinder 220 ttntil the top of the piston arms 224 eon1C into conttict with the pisttm retention hcxnks 225. The retention books 225 retain the pi.atPn 221 sn its position within the piston cylinder 220.

[000101] In the preferred enibodiment, when the dispen.sing spout is in the closed positicxi, the linkage t:lbow 750 of the trigger lirilcage 340 and the slider Iuilcago 260 is alightly hypcr-uxtcndu9 upwardly Ro that force experiencc;d by the triggc;r linkagc 340 and the force cxperienced by the slider linkage 260 are not in the same plune. 'I1ie angle between the trigger linb:agz 340 and the slidcr linkage 260 tnrce diroctions would be greater than 180 d<:6ncc:s on the top side of these two acnnpuncatts and leas Lhan 180 dcgr= on the bottom side of these components.

10001021 Thc hyper-eacte4ded state, as described, would transf'er a portion of the cmptvssitm forc:ex experienced by thcsc Iinkages 340 atui 260 upwardty onto Uue piston arms 224 the slider linkago stop 229, thereby keepittg the compnnents 340 and 260 in a static state. The pruvision of hyperextension in these linkages 340 and 260 provides for greatarr stabiiity to tbc linkages 340 and 260 to prevat an accidental tripping into the de-activation pnsition whcn the spout is in use.
Altcrnatively, however, thc linkage elbow 750 ouuld be a straight 180 degree eonnccticut between the trigger linkage 340 and the slider linkage 260, relying on a sprinp such as the triggar linkages cantilevered rer,d spring 343, which would tht,,n provide the same upwardly stabilixii3g force to prevent accidental tripping.

[OOUIO3) The dial indicator will accordingly change from the 'open' sebting to ihe reset sctting indicating that the auto-shutc>ff candition has oceurrcd. As the auto cla4urc auto shut off spouL 500 is tripped by the piston 221 into the dc-activatim- cxientatirni Lhe spoats slider assembly, 200, will slide relative to the spouts tiwtlc assembly, 100, and spouts trigger assembly 300, which wiU retnain relatively stationsry. Before the auta closure auto shut off spout 500 is tripped into the de-aotivation urientation, the auto closure auto shut off spout is in the open or start orientation and the dial indicatcr step follower 424 is resting on the trunks dial indicator step 124 (se~ Figpre 22).
As the auto closure auto shut oPl'Fpout is tripped into the de-aetivation orientation, the slidLTs dial indicator step 270, which is positioned above the tnutks dial indicator step 124 wiU siide under the dial indicator step Ritlower 424 (see Figure 23). This will eauye the dial indicator 420 to ratate clockwise a h o u t the dial indicators pivot point 412 to d i s p l a - y the reaet t e x t o f t h e dial indicatoi'9 display 421 in the covcrs window 41 1(me Figure 23).

[000104[ ltfter the 'dcactivation' condition has resalted from fill-up, the dispensing spout can be rt:set to its original 'elosed' setting for further use, by simple rcmoval of the dispetsisib spout from engagement with the ri:ceptnele. iJpon disenp,agemcnt, the trigger retutn spring 330 will push the spouts trigger assembly 300, towatds the sliders tip 201 tzlarning the spvuts triggar assembly 300 the original closed posilion. As the spouts trigger assembly 300 is being reset into the closed crcientation the trisger linkage 340 and the Slider linkage 260 will also be maneuvered bauk into their original clcrjed orientation.
As the spouts trigger assembly, 300, moves towards the sliders tip 201, the distanee between tlw siicier linkage axis shaft 226 and the trigger linl-ages axis shaft clasp 323 will increase causing tlte linkages 340 and 260 between them to gtraighten out. The increasing distance will rotatc the trigger linkage 340 couriter cloekwisa about trigb-cr lunkge axis 341 and rotating slider linikvge 200 clockwise about slider linkage nxis shaft 226 until ths linkagCs 340 and 260 ol'the auto c;lusure auto shut off spout are back to Lheir original closed twientation (reference linkage (340 & 260) changes between Fig. 23 and 18).

[000105[ In the pieferred embodiment shown, it will be noted that the trigger linkages cantilevered texAsprings 343 (see Fig. 18, 20,22 and 23) within liAkage meathers 340 help retutu, oriLmt and niasintain the positicx,ing of the trigger linkage 340 and vlider linkage 260 when thc aido closure auto shut o8'spout is in the closed oricntation. The 1'riggex' linkages cantilevered reed sprinp 343 pmvide a counter clockwise mcxnent to th,o Trigger linkage 340, whielt would act to hold the linkage elbow 750 in place up against the underside of the piston anus (scx:
Fig. 1$, 2U,22 and 23).

10001061 It will be appatunl that numerous modifications to the pretixred embodimcnt are possible with<iut doviating froin the scope ol'thc invention.

[0001071 Fur instance, piston 221 diseussixi above cotild also be a flexible diaphragm, ax shown in Figure 25 & 26 such as a bellow 290 with amtq 292 & o-ring 291, which cauld be press fit into the cylituicr 220, that has a step 293 at the bottoin to properly maintaitt its position within the cylinder 220 (see Fig.
25). As the vacuum presstttt: within the spout increases, the llcxible material of the bellows 2>U is defoirned like an accordion drawing the bellows piston arms 292 down so they can perfoctn the r,ame function aa the pistons arms 224 to trip the linkage at the clbow and elosc the valva The resilient material of the bellows 290 would alsu act as its own retum sprinp.

l000i118] Of wnsidci-ation, as well, the style of jet 150, ag shown in the preferred csnbodiment, is cumpatible with all flowing fluids hut nn alternate jet 170 is preferable and advisable when the autcr closure auto shutoff spout of this inventinn is to he used with a contaitter 10 that cmly has one opening. Such an alternative jet is shown in Fibn=s 26. When transfcrring fluid ti'om any container there must be and excltange or qit' for the fluid, which is removed. '1'o transfer fluid 'fitun a containcx with cmly one opening, air caut only be introdaced into the container through the same opening that the fluid is cwiting. Alternate jet 170, as lUustratccl in Figures 26, provides an airway that bypasses the fluid flowing out of the spout allqwing air into the cnntainer, which will suppurt a stcady smooth transfer of t17C fltiid from the containcr. The altet'nate jct 170 can be made to be compatible with txith the nozzle 20 and any standard gas receptacle 10. F''or the gas teceptaale.s 10 with only one opening as t.he 5~pout is opened up liquid witltin the container will begin to flow out through the spout. 'I1iis liquid flow will also produce an airflow into the jets air cavity 154 via the ventuti effect.
With thc altcrnaLe jet 170 air in the jets :rir cavity 154 will also be allowed to flow into the container 10 via the air channels in the jets thr-eads 172. The air eltatulels in thc jcts threads 172 provides an airway that bypa3yc:s the fluid flow making for a srnooth traruxlLr ul'both air and fluid in and out of the wntainer.
10001091 8rietly, the dispensing spout of this invention is tlu: combination of a spout with auto ck>RUt-e and Nuto-shutolT capabilities.

[000110] 'rhe auto auto-closure featurc oI'the spout relate to a fluid flow coturol means such as a valve within the spout which functions to activatc or sLart the flow of fluid tlurough the spout when the xpout is pt-operly mounted to Lhe fill openirig of a reu.ptacte and will stop the ttow of fluid when the spout is pulled a way (yr dismounts tlte receptaale. '1'hia feature:
of the present invention will be discussed in detail below.

[0001111 The auto-shutoff feature of the prcunt invention relates to a deactivation n,cans within the spout, which provides the dispensing spouts with the ability to automatically sliutoff the flow of fluid passing through it upon the rea;iving receptacle bewrning full to the point where tha fluid within the receptacle rises to cxrver and block the tip of the spout.
This type auto-shutoff iunetion is well known in the art but until this point an autu shutult' muans has never been incorporated into a dispensing spout in the way that's discluscd in this invention.

(000112] Thc auto closure auto shut off spout of this invention has three settings or orientation_y that define its funetion; 1) closed, 2) open or start and 3) reset and closed.

10001131 The lirst setting of this auto closure auto shut off spout is its closed orientatiun dclincxi by the requirement that liquid, vapor rrtd or air cannot lealc out or in through the spout which would he attached any liquid sourcc, liquid feeding rncanv or fucl tranYti.h- sryKtcRtt.

[000114J When the disper>,sing spout of this invention is applied to a paL-ticular liquid source it i3 the dclivery trunk body or '1'runk txsdy (120) also latown as casing, whioh acts to se:al that system, '1'hc Trunk body (120) itself has three ru:u'.asary upcrrinp in it, which arc opened and closed to enable the Auto elosure auto shutotl'spout of this invention to ftme;tiun as disoloseel below. '1'he lirst ul'the threw openings is the Trutilc bases ol.miing (139) the second is the Trunk tips opening (138) (see Fig. 21), whioh is also the trLLnks dispcnsing opening and the third is the Trunk bodies airway (127) in the side of the Tnu1k body (120) (see Pig. 4, 5,6, 8, 19).

10001151 When in the closed (500) orientaticm '1'he tirst opening, the Tntnk bases opening (139) is scaled by the Screw cap (190) which is threaded onto the e.oupling meana of either a no:,-Ae or gas container (22 or 43) where the Screw cap (190) snndwieltzs the Ttvnk base (126) and the Jet base (152) up against either- a nozzle Couplers leading c:dgc (25) (see Fig. 4, 19, 21, 24) or a gas eonttriners inlet rim (42) (see 1%ig. 16) providing att airtiglit leak proof seal between the Nozzle wupter (22), Jet (150) and Tnutk base (126) or altentatively a Gas container cciupling mcans (43), Jet (150) and Trttnk basc (126) (scc Fig. 1, 2, 3, 4, 16, 17, 19, 21, 24).

[000116] The second opening in the Trunk body (120) is the 'I'nink tips openuig (138) (soe Fig. 21) and is sealed by the Trunk core (130), whiah is free to slide axially alung the interior ol'thc Tru.til; body (120). It will be app,u=ent that thc truiik core acts us the valve means for controlling the flow of liquid through the spout. When the Auto closure auto shut off spout is in the closed orientation (500) the Trunks spring (140), which is wmpruasod in beLwccn the Jet (150) and the'1'rnnks core (130), providc:s a!'orc:a that pushes the Trunk core (130) towards the Trunks tip (125). 1'hc Trunks tip (125) is tapered tu con:itrict an the umd and thc'1'runk Lips opening (138) is sealed as the force of the spring sarrdwiuhc, the Trunk cores o-ring (131) in betwtm the 1'runk ccm: (130) and the Trunk tips (125) interior providing an airtigllt leak proUfseal (scc Fig. 4, 5, 6, 8, 19).
[000117] The third opening in the Trunk body (120) is sealed by the Cavity created betwccn the trunks lower o-rings (128). 'I'he Trviilc bodies airway (127) fauititatca Lhc spouts auto shutoff Rrnction and when the Auto cloxurc auto shut ofl'spnut is in the closed orientation (500) the Trutilc bodies airway (127) is unable to conununieate or eouvey aqy matcxial in or out ot'the auto closure auto shut off spout (500) because ii is contained by an airtight leak proof Cavity between the trtuilcs lower u-ring:i (128) that's created by thc Trunks n-ring at the base (121) and the 'i'runks middle o-ring (122) whieh are sandwiched in between the Trurilc bodies (120) exterior and the Slider bodica (280) inleriur (see Figure 19).

i00t1118) When the Auto clostre auto shut off spout of this invention is in its closed orientatitm the 9'runk btxiim (120) ilvee optx-ing.s; Trunk bagt-i opening 139), thc Trunk lips opening (138) and the '1'runk btxlie.s airway (127) Hre completely maled.

[0001191 The spout of tlus invention will indicate this closed or ewttled oticrttation with att indication tneans whcre in the prefesred emhoditnent it is Dial indicator (420) whose display (421) will be seen in tlte Covers window (411) (see Fig. 2,14,15, 16, 17, 18, 20, 22, 23). Thv Cover btxiy (410) is providai with a 1)ial incIicator (420) pivotally mounted to its;
intcrior. A hub featurc cm interior of the Cover body (410) providcs the Dial ittdieator (420) with a pivot point (412) whcre axis shafts (422) on the Dial indicators rib (423) is locatcd (see Fig. 14, 15).

1600124) When the Auto ckmure auto 4hut oll'spout is in the closed orientation (500) the Dial indicators step follower (424) on the Dial indicators rib (423) will be in contact with the Triggers dial indicator step (350) which will orient the Dial indicator (420) at an angle tliat aligns the closed teact on the Dial indicator display (421) with the Covcrs wgtdow (411) so it uat be seem (aee Fig. 18).

[t1001211 The seutnd orientation of this attto closure auto shut off spout is its open or start oriuntation which allnws fuel to tlow freely throttgh the spout.

[000122] When opening or activating the auto shut off spout (500) the tip (201) should he placc:d inside a receptacle opening or container inlet (41) where either the Triggeis upper hook (325) or the Triggers lowt:r hook (328) of the rmcptacle cngaging triggc.~r means is rested un the container inlet rim (42) (scc Fig, 16). Once in place anfl properly aligned the ttser will cithcr apply pressure down the length of the Gas station shaped nucde (20) or Prets down on the CaK container (10) with a force along the cxmter line ol'the auto ol(istrre atttt) shut off spout (500), This force will be tranaferred to the Trigger bodies htroks (325 or 328) which are integrally molded into the'1'tigtn.~r txxty (320). The tip<tuts trigger assembly (300) will then c:emvey that force to the Spc-ttts slider a...'rembly (200) via a linkage means, which is in the enabicxi etmt'aguratiott, 17he: linkttga mutns cottneuting the '1'rigger body (320) and alider assetubly (200) will cause the Spantt3 slider asscmbly (200) to slide axially along the Spouts ttwtk assetnbly (100) towards the Trunks base (126). (see the change in position uf assemblie,s 100 & 200 hctween rig, 18 & 20). 'I'he force tr.+nsfen-ed Lu thc Sltouls slider asacmhly (200) by the SpouLc tri88er as,setnbly (300) will have bucm fiutiter transtesrred to the Trunks Core (130) via the Trtuilc cores tip ridge (133) which is in contact with the Slider bodies (280) F,xit grate (250) (see Fig. 21) and that foree will have been transfeired throagh the'1'ranks curc (130) to the Tsvnks spring (140), which will hnve beaome fiulher eompressed as the Trunks core (13U) slid alung the interior of the Trtmk body (120) witlt tltn movement of the Spouts slidtx assembly (200) (see compnnent changes batwccn Fig. 19 & 21). The rnovctnent of the Spouts slider assembly (200) will have tmseat the '1'runk eres o-ring (13 i) unacaling the'1'mnks tip (125) to allow tluid to flow through the Jcl (150), down the length of the Trunk body (120) around the 1'rnrdcs core (130), out the '1'runks tip (125), into thc interkw of the 5lider body (280) and past the Exit grate (250) out of the cpout (sec Fig. 21).

10001231 'I'his open or start orientation is indicated by the Diul indicato-' (420) wltose display (421), can be secn in the Ctwcrs window (411) (see Fig. 14, 20, 22).

[000124) When the Aato closure atitu sltut off spout is in the open orientation tlte I]ial indicatcm step follower (424) on the Dial indicators rib (423) will be resting on tlte Tivnks dial indicator step (124) (mx: Fig. 20).

[000125) As the Spouts Tri(;gcr assembly (300) and Spottts slider assembly (200) were moved axially nlung the Spouts ttvnk a.tiqcmbly (100) towards the Trunkx base (126) the SpQuts cover as+trnbly (400), which is attached lo the Spottts trigger assembly (300) was catried altmt; with them. As all tluve of thc-vc assesnbiies (200, 300, & 400) moved togctber, the Dial indicatot's s'tep follower (424) will have oome iu uonlact with the '1'r6tr>ics dial iudicatc-r :stt:p (124). The Dial inciieatpt:s,stup follower (424) will have titen ridden up cmto the Trunka dial indicator step (124), wliic:h will rotale the Dial itxiieator.(4220) clockwise about the 1)ial indicators pivot point (412) so that the center area of the Dial indieator display (421) which reads start will apper-r in tha Covcrs wiiidow (411) so it cnn he seen (sce Fig. 20), [000126) '1'o clnse or turn the spout off the olx. rnt4,r will just sitnply take thc nrn..zle away from the Gas container (40) (see Fi{l. 16). At which point the lorco that was applicd to the Auto olosure auto shut off spout (5W) to open it will have been removed and the Ttvttk spring (140) will rettun the Trunk core (130) back into itsi elosed cxientation (scx: Fig.
17, 18, 19) where the fot+ce of the apring will stutdwiehe.w the Trunk eotes o-rittg (131) in between the '1'rtuilt ccxe (130) and the Trmik tilis (125) inlcxior to provide and airtight leak proof seal (see Fig.
19).

[000127] The auto olu.sure featurt: automatically retunis all tttc spouts aornponents to their closed airtight Icak proof orientation as the spout ia taken out of usc.

[000128] The third oricntation of this auto clostuc auto shut off spout is its nesct and closed orientatiun. This is where Lhe operator will have opened or started the spout but the spouts auto shut off featurc iias been activated, which has sealai the spout closed cutting off the tlow of fluid exiting the spout.

10001241 The function of this invCntious auto :httt off feature is similar tu that of a standard gas atation nozzle in that the auto 4hut off tnechanistn is triggered as llte fluid level in the Gas container (40) rises to utver the tip of the spout anti this featurc enables the spuuL ui tietect the pro,eintity of dixpcmaed liquid in the receptaole.

[000130] 1'hr: design of the nutu closure auto shut off spout ol'the presettt invention takes advantage ot'the fluid dynamics within the Spouts trunk assembly (100), whieh has been configurcd to crexte a venturi (scc Fig. 3, 4, 5, 6, 7, 19, 21, 24). As the fluid leaves the Jets tip (151) it will expand beconting turbulent, The 4xpansion and turbulence ul'the fluid fiow will cause the fluid Lu pick up and mix with air within the Trunk body (120) and that air will be taken with the fluid flow ay it wtiits the spout.

(000131] The fluid flowing through the Tnink body (120) will crcatc a negative presRUre within the Tnuilc body (120), whicb will oonGnually want to draw on air as the liuid is flowing and to facilitate this desired airl9ow, an airway iiont tht:
exterior of the spout into the inteaior of lhe Trunk body (120) has been provided (scx: f'ib. 2I ).

[000132] As thc Auto closure autn shut off spout bad been actuated into the open orieutatiun (referenoe scction 0029-1) an airway was also upc-nod up between the exterior of thc spotit and the interior of the Trunk body (120) (see rig. 21) to allow airflow directly into the Ttutlk body (120). As the Spouts slider ewtnlily (200) moved alonb the Trunk body (120) the hole in the bottotn of the F'iston aylinder (228) (see Fig. 11) became aligned with the Cavity bctween the trunks lower o-rings (128) (.sze Fig. 19, 21, 24) creating an airway intn the Trtutk bodius (120) inlerior (see Fig. 21). This aligruncnt fornts an air conduit that now allows air to cnter the spouls air opening or Air inlet tip (241) flow down thc sliders Air channel (240) into the 1'Istans eyllndcT (220), down through the Cylinders bottom air hole (228), into the Cavity between the trttnks lower o.ringK
(128) and then through thC Trunk budiaa airway (127) into the Trunk bodies (120) interiur (see Fig. 21). The air itttrcxiutxd into thc trunk body will c:nter behind the Jcts tip (151) into the Jets air cavity (154) where this t;ottfiguraticxt hclnt prevent fluid frotn guing directly utto the 'i'lunk bc+dfes airway (127), '1'he Iluid flowing throuRh the trunk body (120) will exit the Jet:i tip (151) where the venturies turbulcnce rvill draw on the air inside the Jets air cavity (154) through the gap, whieh fs between the Jehc lip (153) and the Trunk bodies (120) interior.

[000133] Tf at this point the opcrator would like to stop tilling be~ore the uutu shutoff fimction is activated thc op..rator wxalld again just siniply take the ncrr.Jlc away from thc C,a.s containCr (40) (see 1'ig. 16) to stnp the flow. The 1'runk tips opening (138) would be automatically resealed by tltC autu closure function and as well, the airway that had been opened up lx:twu:n thc exterior and the inter'tot' of thc spout would be interrupted ax ihe Cylinders bottum air liole is moved out of aligntrtcnt with the Cavit,y betwct:n the trunks lower o-rin$s (128) (see Fig.
19), 10001341 The auto closure lcuture will heve auttmsatically rettuncd all the spotits uomponents to thoir clo-sed airtight Icak proof orientutiun as thc ,pout is taken out of use.

[000135] If the opcrator continues filling, the auto shutoll' I'aal-ce of this invention would be activated as the fluid level in the Cra.r container (40) reached the Air chunncl:t inlet tip (241). As the Air channcls inlet Lip (241) is covered by the rising fluid in the Gas container (40), air would no longer be able to entcr the Air channels inlet tip (241) and that would cause the negativc vacutau pressure within the Air chanucl (240). Pistons cylinder (220), Cavity between the tnmks lower o-tings (12$), and '1'rilnk bodies (120) interior to increase. As this vacuum pressure builds up within this systenr it will get to a point where that pressure will begin to act on the spout8n pressure rcsptuisive means within tiie spotit wht:rc in the prCfomcd Lvnhodiment it is a piston nzcans whet-e that Pititon (221) will be drawn down (see Fig. 22) so that this downward nmtion of the Pistons (221) will itt tum act csn the Slider linkage (260) whieb also knuwn as the seeond linkage and tlx. Triggc:r linkage (340), which alsn known as the first linkage via the Pistun arms (224), which will be pushing the Linkagc elbow (750) down (see Fig.
22).

[00t! 1361 The fon:e applied to the Spouts trigger assembly (300) needcd to open the spout had been cxtnveyed tivoufrJi the Triggcr linkage (340) and was transferred to the Spouts slider aysLrnbly (200) via the slider littlcage (260) causing the Spouts trigger assembly (300) and the Spouts slider assembly (200) to ntove togethcr as they slid axially alcmg the SpouL4 truiilc axvumbly (100) towards the Tnuilcs basc (126), The auto sltutoff foature of thia invention works by relieving the Spouts slider assembly (200) of thc force beittg transfen ed to it by the Spouts trigger assembly (300). As the lluid in the (3as container (40) reaches the top it will cover the Air channels inJet tip (241) causing the vacuum pre.mttre in the airway to increase which will pull the Piston (221) down disengaging the rigid connection between the Spouts trigger assembly (300) and the Spouts slidouT
asac.'mbly (200) (see Fig. 23).

[000137j '13te Piston arms (224) extending from the side of the Piston (221) will push down on the Linkage elbow (750) whielt will rotate the Trigger linkage (340) clockwise nbout 'frigger linkage axis (341) and rotating Slidc.,r linkage (260) ceunter clockwise about Slider linkage axis shaft (226) till the point where the force being trensferred betwewt these linkages (340 & 260) is relieved (see Fig 23). In thc present invention the'Tiigber linkage (340) will havc rotated elookwiw:
abottt Trigger linknge axis (341) to be pointing below the horincmtal and the Slider linkage (260) will have rotated wuntcx elockwi:u: about Slider linkage axis shali (226) to be pointing in a downward direction (sec Fig 23)= The piston (221) ot'the auto shutntl'or deactivatitm feature will have changed the linkage means from the enabled umtiguration ol'the linkage means to thc: diyabled contlgttration.

(000138] 'I'his action will have disengaged the ridged connection between the T.,inkages (340 & 260) rLvnoving the foruc on the SlxKtts slidcr assembly (200) and that will allow the Trunk spring (140) to return thG Spouts slider assemhly (200) to itx originnl closed twientatir,n (see Fig 17, 23, 24) while the Spouts trigger assc~nbly (300) remains in place (scc Fig.
17, 23, 24), With the forue on the Spoutg :dider assembly (200) gone, the Trunk spring (140), which pushes on the Spouts slider assembly (200) via the'1'runk corc (130), will spring bnok rctuniing the Spouts slider assembly (200) to its closed oricntation (see Fig 17, 23, 24)= In the same motion this aotioa will have also rctttrned the Trunk eot=e (130) to its closexl tui,entation (sce Fig 4, 5, 6, 7, 8, 19), scsling the Auto closure auto shutoff,Trout closed (see Fig 17, 23, 24). The Trunk core (130) will have been rcturned to sandwiched the Tnwk cun:r u-ring (131) in between the Trunk core (130) and the Trunk tips (125) iuttetior to provide and airtigltt leak ptt,of scal at the '1'runks tip (125) (sde Fig 4, 5, 6, 7. 8,19). As well, the airway that had been opened up along the Air Chatwel inlet tip (241) tltrough the Piston cylinder (220), Trunk bcxliea airway (127) intki he Trunk bodies (120) interior will have been intenuptctil as the Spouts slider assentbly (200) is tr.htrned to itsR closed oriatation (see Fig 24). As the Spouts sliduT asscmhly (200) slidcs axially along the Trunk body (120) back towards thc 'I'runks tip (125) the pietton Cylinders bottom air hole (228) will move out of communicatien with the Cavity betwGen the trunks lower o-rinp (1 28) to intc7rupt t.he airway that Itad buCn cstoblisheci as the Auto closure auta shut off spout had been opened ./1s tlie Autu clnsiue auto shut off spout had actuaied into the ivsel orientation the pistoi't Cylinders bottom aii hole (228) will have move axially along thC '1'zunk body (120) i'rant the Cavity between the trunks lower o-rings (128) to the Cavity between the tnuilcy upper o-rings (129) (re1~.~uce changes in air hole (228) location betwean Fig. 21 and 24). The Cavity between the trunks upptr o-riags (129) is formed by the Ttlinks o-ring at the tip (123) and the Ttlinks middle o-t=ittg (122), which are sandwiched in between the Trunk bodies (120) eatterior and Ihe Slider bodies (280) interior (ace Figure 19).

[0001391 This reaetion of the auto sl-ut off fc:ature wi1F have retumed tlle Cylindc:rs bottom air hole (22$) of the Spouts slider assenibly (200) and ilic Trunk c,nre (130) to an orietttation that pruvideg the'1'runk body (120) wiih an airtigllt leak proot'sea] (see Fig 17, 23, 24').

[000140) As the auto yhutoll' Ycature is activated in the Auto closurC auto slnttA)ff spout the flow of f'luid will stop flowing thtnuglt the Auto closure auto shutol]'spout , As the flow of tluid stops, the vcnturi vacutnn pre.v.surc produced by the flowing tluid will a1,so stop and in the absence of this n4gative pressurc thc Piston (221) that had been drawn down by the vacuum pressure (see Fig 22, 23) will re=ttttl1 to its original orientation (scc: Fig 24). In thC abstmee of the vacuum pres-sure the Pistonrs rutwn spring (223) will push the Piston (221) back up the Piston cylinder (220) until the top of the Piston anns (224) come in cxmtaet with tlie Piston retnnticm hooks (225) which hold the Piston (221) in plttce within the Piston cylinder (220) (see Nig J, 10, 1 R, 20), 10001411 The prefcrt=ed embod'unettt of the invcntion would be tbat wllen tlio Auto closure atito shutofj'spout is in its elosui and open orientatiun (500) the Linkage elbow (750) of the Ttiggcx linkage (340) and the Slider linkagu (260) would be slightly hypt,=r-cxtended upward (see Fig 4, 5, 18, 20) tin thut the fonae traveling along the Triggc.7linknge (340) and the fi,reu traveling along the Slider liiilcage (260) arc not in the samc plane. The angle between the '1'rigger lunkage (340) and the Slidt-r linkage (260) would be greater than 180? <m thc: top side of these two wmponenta (340 & 260) and iem than 1807 on the bottont sidv (acx: Fig 4, 5, 18, 20).

10001421 This hyper-extcmded stote would ttim a purtion of the eanpressiun fotws with in these linkages (340 & 260) ituo a alight upward lorce on the Piston arms (224) and Slider linkage stop (229) (sec: Fig 4, 5,18, 20) which would serve to keep these components (340 & 260) in a statio state as force is appliod to open the spout. The provisiou of this hyperexteaYieut in the linkages (340 & 260) would provide for grcater stability to the linkabm (340 & 260) transfirring the force and would work to prevent them fibm accidentally tripping into the reset orientaticm (see Fig. 23) as thc spout is in use, [000143] Alternatively the Linkage elbow (750) cxtuld also be a strait 1807 connection betwo:e the Triggei-linkage (340) and the Slidcx linkage (260) which would rely on a:rpring suuh as the Triggrar linkagc:s cantilevered reed aprittg (343) to pmvide the santo upward stabilizing foncc in order to maintain a static tigid cortnection preventing the Linkages (340 & 260) tFom aeciclentally Uipping into the res<:t orientation.

[000144] Au the Auto closLse auto shut oEt'spout is tripped by the Piyton (221) into tl-le tvsct orientation the Srouts slider amembl,y (200) will slide n:lativu to the Spouts trutilc a.y:x.-mbly (100) and Spouts trigger assembly (300) which will renaain relativcly stationary (sca Fig 17, 23,24). Before thc Auto closure auto shut ott'spout is tripped 'uilo the reset orientation tho Auto cloaure auto shut olf spout is in the open orientation where the 1)ial indicator step follower (424) is resting on the 'I'runkr dial indicator step (124) (see Fig. 20, 22). As the Auto closure auto shut offspout is tripped into the reset orientation the Sliders dial indicator step (270), whicli is pasitioned above the Trunks dial indicator step (124) (see Fig. 18, 20, 22, 23) will slide under the Dial indiuator step followcr (424) (aec Fig. 23) which will causd the Dial indicator (420) tu rotate clockwise about the Dial indicators pivot point (412) to display the reset text of thc Pial indicators display (421) in the Covers window (411) (see Fig. 17, 23, 24).

1000143J To reset the Auto closure auto shut o8'spout the opmtor will just simply take the nozsle away tirnn the Gas exrntainer (40) and as the foroc:, which was applied to the Auto closure auto shut off spout (500) to open it is reTnoved (reference section 0026-1), the Trigger return spring (330) will push the Spouts trlgger assembly (300) towards the Sliders tip (201) retuming the Spouts trigger asst.7nbly (300) of Auto closure auto shut off spout to its original cb,gr.d (500) oritaitation.
[000146] As the Auto closure auto sliut oll' spout was tcipped into thc reset orientation the Spouts slider assembly (200) had slid forward relative to the Spouts trttnk assenibly (100) and Spouts trigger aasLxnbly (3tx)) which had remained relatively stationary (see Fig. 17, 23, 24). In doing st7 thc Trigger return spring (330) in between the Spouts slidc:r as'tcmbly (200) and Spouts trigger assembly (300) had been compresaed (refernrxx: changes in the Trigger rcttur spring (330) bctwecm Fig. 19 and 24). Now, as the foroe, wluch was appliW to the Auto closure auto shut off spout (500) to open it is removed the Trigger n_-tuxn spring (330) will be able to expand to push the Spoats trigger assembly (3()0) along the Slider body (290) u-wards the Sliders tip (201) returning the Spouts trigger assetnbly (300) of Auto olosure auto shut off spout to its original cloxed (500) orientation (see rig. 3, 4, 5, 18).

[0001471 As the Spouts trigger assCrnbly (300) is being reset into the closed (500) orientation the Trigger linkage (340) and the Slider linkagc: (200) will also be being ntaneuvsTc:d baek into thcir original closed (500) orientaticm. As the spouts triggc:r assembly (300) moves towards the Sliders tip (201) the distance between the Slidur linkage axis shaft (226) and the Trigger linkagc.g axis shaft clasp (323) will inotcasc causing the linkages (340 & 260) between (han to straiteri out (rcterence linkage (340 8a 260) changes bctween Fig. 23 and 18), The ins:reasing distance will rotnte the Triggc:r linkage (340) twunter clockwise about 'Crigger linkage axis (341) and rotating Slider linkagc (260) clockwise about Stider linkage axis ahall (220) until the linkages (340 & 260) of the Auto closure auto shut off spout aru baclc to their original closed (500) orientation (rofixence linkage (340 & 260) changes betwsxn F'ig, 23 and 18).

[000148[ 'l'he: preferred embodinient of this invcnticm would provide a spring such as lhe Trigger linkages oantilcvcrcd reed Springs (343) (see Fig. 12, 13, 20, 22, 23) within the linkage systetn (340 & 260) which would help return, orient and maintaui tlte posilioning of the Trigger linkage (340) and Slider linkage (260) when the Auto clvsurc auto shut off spout (500) is in t}te closed orientation. '!ne Trigger linkages cantilevered reGd springs (343) (tihown in Fig. 12,13, 20, 22, 23) would provide a counter clockwise moment to the '1'rigger lirilcage (340), whiah would act to hold the lankage elbow (750) in place up against the rmdcrside of the Piston arms (see Fig. 4, 5, 18, 20, 22).

stcf, Ibllower (424) which had heen resting on top of the Sliders dial inilicator step (270) (see Fig. 23) will be moved to the '1'riggere dial indicator stcp (350) (see Fig, 18). Aa the Spouta trigger assc:mhly (300) moves along the Slidc:r body (280) towards the Sliders tip (201) the CovLrc body (410), wltich carries the Dial indictor (420) will trnvel alcmg with it. As the Spouts trigger :-.csenbly (300) and Cover body (410) move along the Slider body (2$0) towards the Sliders tip (201) the Dial indicatcro step foliower (424) will movc off the 5liders dial indicalor step (270) and as this occura, the Ribs cantilevered re:ed spring (425) will rotate the Dial indicator (420) cotmtcr clocktivise ahout the Dial indicators pivot pcrint (412) (reference Dial indieator (42(l) changes between Fig. 23 & 18) so the 1)ial indicators step follower (424) will comc to trst on the Triggers dial indieator step (350). This will havc aligned the closed text on the Dial indicator disPlay (421) in the Covers window (411) (sec Fig. 2, 16, 17, 1R, 19), [000150; The piston (221) discu.r:;ed above could al.cu, hc a flexible diaphragtn such as a bellow (290) with anns (292) & trring (291), which cxx,ld he pnass lit into dx; Cylinder (220), that has a step (293) at the botttrm to properly tnaintain its r,cxsition within the Cylinder (220) (refixonce Fig. 25). As the vacuum pres.sure within the Spout increasc:s the flexible matu-ial of the k3ellows (290) would deform like an accordion drawing the &:llows piston arms (292) down so they can perform the sante flu-utitm as the Pistons at-nts (224) The flexible matefial of ahe Bellows (290) would also act as its own return spring.
