The np ef s11fface of the diStfibutof plate 23 fS pfovided vvith an annulaf feceSS 32 that has n1ounted thefein a lowef valve plate 33. A sealing gaSket 34, vhich filay be a fubbef o fing, iS intefpoSed befvveen the plate 23 and valve plate 33 to pfovide a Sea1 thefebetvveen. Opefa tive1y affanged With the 1owef valve plate 33 iS a valve se1ectof fflefflbef 35 having a hofizonta1 WaH poftion 36 equipped vvith a depending annulaf contact n1en1bef 37 that S1idably engageS the Uppef Sufface of the va1ve plate 33. A stem 38 is foffned integfa11y With the hofizonta1 poftion 35 and eXtendS upwafdly thefeffom and iS equipped with a slot 30 that iS adapted fo feceive tho point of a ScfeW dfiveT So that the Selecfo1 IneInbef may be tnfned felative to the vave plate 33. A globulaf c1oSfe I1eff1bef 40 1-eceiveS fhe uppef end of the steI]1 38 and has a downWaTdly eXfending central poftion Suppofted Upon the outer perphefal ouTface of the valve late 33. The n1embeT 40 haS outWafd1yand downwatdly eXtending vvall poftioos 41 that sobSfantially eIlclose of covef the distTibutof plafe 33 While being spaced thereffoIn aS at 42 to peTInit the ow of liquid betweon the plate 23 and the WaH poffionS 41 of the closore. helical SpTing 43 is Inounted abouf the Sten1 38 and seatS upon the hofizontal )oTtion 35 of the valve selectof 35 and upon the uppef wall of the cloSufe n1e1beT 40 and' nofmany biaSes the selectoT membef downwafdly and into engageent vith the Uppef Sofface of fhe lowef valve plate 33. A p1UTality of Studs 44 extend thfough aHgned boTes wifhin the cloSUTe nlen1bef 40. valve )1afe 33, and distfibufof Plate 23, and SecUTe an thTee of theSe ITlen1- befs togethef. It iS appafenf that tflo eI1fife head C of the dispefSing apparatuS fofateS Upon actuation of the n1otof.

AS win be Seen best by fefeTence to Fig. 4, the valve pate 33 is pTovided vith thTee spacedapart openingS 45 thefethfough that afe adapfed to feceive the sfudS 44. The plafe 33 is also pTovided vvith a plufality of Lshaped ovv paSSages 45 thefethfough that have a hoTizoota11y extending poffion 47, and a veftical poftion 48 in open con1n1Unication vZith the hofizontal passage 47 and with the U peT S11Iface of the valve late 33 (Fig. 2). The valve plate 33 and the Selectof n1enlber 35 pfovide thefe befvveen a valve chaInber 49 and the LShaped ovv paS sageS 45 conTII111nicate v/ith the valve chan1ber 40 thfoUgh n1eteTing ofi0ceS 50 in the contact poftion 37 of the Selectof Inen1bef 35. Control ovef the quantity of liquid Hovving thfough the valve chan1bef 49 and on fo tho dis tfibutof plate 23 iS pfovided by Selectively fegiStefing the desifed nlefeIing oTi0ceS 50 With the veTtical paSSage poftions 33 and the L-Shaped paSSageS 45. The nletefing aduStInent of the valve SelectoT 35 iS accoInpliShed by Totation of the Selecfof Inembef Within the lifnifS pfo vided by the TecoSSeS betvVeen fhe Upvvafdlyextending abutmentS 51 caTried on the npper SuTface and the hofi- Zontal plate 35 of the Selectof IneTnbef. Stop pin 51o cafed by the doSure membef 40 coopefates ith the abutnlents 51 and thefeby lin1its fhe peTn1iSSible fotation of the Selecfof n1en1ber 35. AS iS Seen in Fig. 3,` the selectol membeT 35 n1ay be pToyided with an additional SeTieS of nTetefing ofiffces 52 diaInetricany op oSife the Inetering ofi0ceS 50. The mefefing ori0ceS 52 afe nof mally inoperative but may be bTooght into opeTative affangen1ent vifh the oaSSageS 45 by fotating the Selectof ITleII1ber 35 180 degreeS relative to the valve plate 33. Such fotation cannot be accon1plished without diSaSSen1 bHng the Specic apparatuS iHUStfafed in Fig. Z.

In operation the feSeTvoi1 iS HHed vvith an appfopriate liquid Solution that nlay be an insecticide, herbicide, of othef foxic nlate1-ia1 that iS S[1itable foT fhe paftioIllaf USe fof .Which the appafatUS Will be employed. T11e Inotor vithin the Inotof housing Will be connected to a suifable source of povver and Upon actuafion of the nofof thfo11gh a. SvVitching arfangeInent of aIly deSiTed foTn1 fhat IIlay be incofpoTated vvith the n1otof, the Iflotof iS actllated and the dSpefsing head C win be Totatively dTiven thefeby. 1ofation of the head C vvill cfeate an aif StTean1 that 0oK/S UpvvaTdly about the throat of the Inofof and thro0gh the centTal opening 31 in the difection n1em bef 27. The air Stfeam Will 0ow UpWafdly withi1 the difeotion nleInbef 47 and vvill pfovide a Sheath of layof of ai1 ovef the innef Surface thefeof.

1otatioI1 of the he d C Will alSo ofeate a felatively low p oSsofo 2one yitf1i1 the s1=,ace pfovidod betWeen the cloSufe IneInbeT 40 and the diStfibllfo1 plate 23 and the atn1osphefic pfesSUfe within the Teservoif will fofce the liquid thefein upwafdly and thfough the hoHow n1otof Shaft 18 and into the valve chaInber 49. FfoIn the valve Chambef 40 the liquid wi11 0ow throUgh the mefefing ofificeS 50 that afe in fegiSfer With fhe LShaped pasSageS 45 iI1 the lovef valve plate 33 and outVvafdly thefefToIf1 and on to the uppef suTface of the diStfibutof plate 23. The liquid Will travel outWafdly ovef the uppef Sufface of the diSfributor plate 23 aS veTy fine dfopletS of liquid afticIeS and will be thfown ontwaTdly ffon1 betvveen the plate 23 and c10Sufe n1en1bef 40 and into the aif stfean1 fhat iS pfovided about the peIiphefy of the disffiblltof plate 23. The air Stfeam wiH Caffy the 0ne dTopletS U wardly and oUtvvardly whefe fhey W be diStTibuted as a 0ne S fay of miSt by the ail Stfeam.

In actnal opefation of the apparatuS the difection plate 27 iS CoveTed 011 the inner Suffaoo thefeofby a layef of mm of ail and the tiny liquid dfoplets diSchafged ffon1the diSfIibotof plate 23 do not iInpinge Hpon the diTection plate of guafd 27. but are caffied upvvafdly by the aif Stfea n and do not contact the difection plate. The difec tion n1en1ber 27 fenlains dfy dufing the opeTafion of the appaTatuS and thefe is no waStage of the liquid thTough collection of the 1iquidthefeon. SiInilarly since the liquid particles do nof iIn inge u on the difection plate 27 thefeiS no coaleScence of fhe liqI1id parficleS due to any iI11ping ing action. ThiS fesult is not achieved if the difection -ITlefI1bo1 27 is not in1perforate and it is then desiTablB to provide a difection plate that iS inlperfofate thronghont itS enfffe afea.

- Many of fhe insecticideS, etc. 11sed in dispefsing appaa fuS are quito exponsive and it iS thefefofe doSifable to diSpefSeonIy the anloUnt of liquid that iS neceSSaTy to acoon1plish a given feSI11t. I/feteIing valve IneanS is )fovided thefefoTe So fhat the aInount of liquid feaching tho distTiblltof plate 23 fn ay be accufately contfo]led. This TeS11lt is achieved by pfoviding a plI1fality of fnetefing oIificeS 50 that vary in size. Thefefofe, by bfinging Selectively the Tequifed ofifices 50 into coIT1Inl1nication With the L Shaped assageS 45 only flle amoUt of liquid that Can 1 low thfough tho selected ofifice vill be delivefed to the diSffibutof plato. To pefmit feady adioStment of the ofificeS it is pTefeffed that the uppef SI1fface of tho Seleotor Sten1 30 be equipped vvith an affovv o1 poinfef aS iS indicated in 1=ig. 1 and appfopfiate indioia nay be Stamped upon the upper Sufface of the cloSufe n1elnbef 40 and aligning the affovV With the pTopef InaTking I1pon the cloSuTo fnen1ber Will pfovide the desifed ow rate. Appropfiately the n1afldngS upon the closure membef Inay be calibfated in ounceS of 0ow by unit of tiIne, Such aS nlinllteS, hoUTs, etc.

It is apparent by refeffing to Fig. 2 that the olosufe IT1eII1bef 40 covefS Substantiany the entife upper snfface of the diStfibutof plate 23. ThiS offangement TeSUltS i1 a Telatively quief Zo1e of ai1 about the diStIibutof p15te and there iS littlo tendency then toW aTd tUTbulence and coaleScene of the tiny liquid pafticleS vvin not be oansed by air turbulenoe.
