froned into a firSt poSition connecting the filtef ontlet 114 to fhe Spin tub 8 and a Second 1)oSition connecting the 11lter outlet to a SUInp refuTn liIle 13. (;ofnplefing the cifcu1ating SysfefT1 is a conduft 135 vvhich connects to the drain outlet 4o of the solvent confainef 34. ThiS conduft 136 enteTs he suIn b wa of a button tTa 138, acceSS to vhich is gained thfough a feInovable lid 10 foT cleaning the ffap device aS vVell aS for adding additional solvent to t11e sySten1. A Sight glasS 142, of othef Sllitable fneans, n1ay be USed for pDoviding a viSual indication of the dry Cleaning i1L1id level in fhe SUnlp,

The nuid circulation System operates aS follovS, The ounlp 10 dfaVvS dfy Cleaning HUid of Solvent ffon1 the sunp 80 thfoUgh the di tube 110. T11iS dfy cleaning Huid, cleaned of large obiects by fhe tfao 138, is fofced through the conduif 118 to fhe filtef 115. The f11fer is effeofive to f11feT So1all SolidS and solubleS from fhe dfy cleaning f1LIid. Affe1' an additional pefiod dufing Which the valve 128 TetufnS the solvent to the sunp and the so1 vont iS Tecifculated to fen10ve parficulate fnaffef ffoIn tho flfer, the valve fS actuated to a poSition Wherein the filtefed dTy cleaning 11Ilid iS diSchafged ffoIn fhe f1lter by vay of the conduitS 1Zo and 130 into the spin t11b. When the level of the dTy cleaning HUid within the tub feaches t11e outHovv oftS 52, the dry cleani1g f1uid wnl oveTnow into fhe Solvent confainer 54 and fefufn by g1avity thfough the conduit 135 to fhe Sum 80, -the butfon trap 138 intef- Copting its How to emove large obiectS ffom the ffUid,

To operafo the Se1f-Service dry Cleaning eqUipfflent, one placeS clothes Within the Spin fub 43 and initiates the cycle. (nce the solvent iS pun1 )ed to fhe Spin tub and the agitating and Spinning mechaniSm 58 is opefated fo fecip Tocafe tho agitatof o, the Solvent vVin be sufged thfongh the fabficS fo feInove the dift and soil therefroTn. Thfoughout the dry cleaning cycle, fhe Solvent Wifhin tho tub win become lTore contanlinated. In the prior art de viceS vVhen the nlechaniSm 58 is energized to Spin the tub 48, the clofhing would luInp info a fofoidal or doUghnut fofm generany blocking fhe otHov poftS 5Z of the tUb. In fhiS faShion, the Solvent would bo centfifUged froIn the Clothing and the tub through the outHovv pofts W ifh a liIT1ited pof tion of the clotheS load seTving aS the f1a1 Strainer of the solvent being centfifnged, ThiS Stfaining action causes Stfeaking of the fabric in the afea of the outi1oW )ofts and a genefaHy 11nSatiSfactofy cleaning Te- Sulf- In accoTdance vVith this invenfion and with feference to FIGURE Z fhe Spin tub 48 iS pfovided With a ClotheS guafd Shovn generany at 150. Nofe that the Spin tUb 48 is forIT1ed Vvith a balance ring 15Z, the innef edge of vv11ich fofIns the acceSS opening 54 fo the tub infefiof. A eneTany veftical but SomeWhat outwafdly tapeTed of bowed Side waH 154 of fhe tub nlergeS info a boftom WaH 156 underlying the agitator and inclIldoS Spaced invafdly di Tected stren thenin ribS Such as 157 FIGURE 3 It is the pufpoSe of this invention to )rovide a clotheS guard 150 Which Snngly engageS the Uppef tefII1inuS 158 of fhe tub Side WaH with its 11pper edge 160. LikewiSe, fhe lower edge 152 of the clotheS guafd Snugly hugS fhe lower end 164 of tho Side vVall. PeffofationS 166 conplotely covef the g11ard of Sleeve and pfovide a n1yfiad of eXifS for the solvent leaving the clothing on its vvay to the outoW poftS 51. The clotheS guard 150 is spaced froIT1 the side vvaH 154 to fofln an annulaf chafnber 168 Which pfovides a paSSageway inteTposed betveen the erfofafionS 1oo of the cl`othes guard and the outHow ports 5Z. In thiS faShion, fho Solvent being Contfifuged froIn the c1ofhing leaveS the clothing over a lafge area thrOUgh an of the many pefforafionS 15o, a fact Which fevents fhe Solvent fron1 being strained thfough a liIf1ited afea of clothing lufnped in ffont ()f the outf1ow oTfS 5Z.

The clothes guard of Tetainer 150 is cofnoTiSed of a genefaHy Tectangular, nylon coated Sheet of oefforated Inetal which haS itS tern1inal ends 17o, 171 1ying in iux-faposifion When the clothes gLlard is vvfap ed in to a cylindfical fofT1 and placed in the spin fub4 DopfeSSed notcheS 174, 176 are porfed to Teceive faStening IneanS, Stch aS ScfewS 178, 180, in 3. plaSfic Spacer bfacket 182 of acetal feSin of equivafent vhich eXtends coIn )letely over the ternTinal pof tionS of the clotheS guard and includoS a I)efiphefal sidevall 1f3 WhiCh snugly hugS the guafd to pfevent bypaSS ing of the Solvent at tl1is ooint, Said peri hera1 SidewaH having a feentry poftion 185 parfiaHy enveloping the fib 157 FGURE 3 With Teference to FIGURES 4 and the tub Side vvaH iS Sho n Spaced genefany unifofInly, eXcept at itS uppof and lower endS, ffom fhe )effofated dotheS guard 150. At Spaced 1)ointS abont the oeTiphefy of the inStalled guard ring, a buged-OUt poftion 184 is pfovided to Inain fain the spacing of the clothes guaTd fToIn the tub vvalL The guard iS atfached to the S in tub 8 in fhe fol lowin manner and with TefeI'ence to FIGURES Z and 6. t Spaced 1oints about the uppef edge 1o0 of the guard, a. p1UfaHty of tabS 18o aTe faStened as by Welding. TheSe tabS 18o afe pe( ated to Teceive a ScreW 183 Which is refained in a b et 190 on the oufside of the Spn tub. The ScTew ioio the bfacketS and 18o by eXfend ing through ono ho oufHowoortS 52. T11uS, the clothes gUafd iS Tefained on the Side v aH of the Spin tub to foffn a channe1 ffon1 the bottoIT1 of the guard fo the outHow poftS. The oeffofated guard holdS the clothing away ffon the out0ov poftS So fhat the solVonf viI1 Inove even ly of be cenffifuged unifoTn11y ffon1 the fabric aS they lie along the guard. hiS affangen1ent pfeventS Sffeaking and effectS an iInpfoved dfy cleaning feSL11t.

ft Should novl/ be Seen that an iInproved spin tub for a verfical tUb dfy cleaning appafafns haS been pfovided v/hich fevontS Streaking of tho clotheS by n1ainfaining an unobStfucted path for the solvent fo be centrifuged ffom the S in tub and the clothing.
