APPARATUS FOR CLARIFICATION 0F GASOLINE.

Application filed February 23, 192A. Serial No. 694,608.

for cleaning clothes or fabrics and for thereafter clarifying the cleaning solution and making it possible to use this solution repeatedly thereby reducing the cost of the cleaning; and to provide means whereby the apparatus may be readily cleaned whenever necessary; and to provide apparatus so con structed as to reduce the ire hazard to a minimum. We attain these and otherobjects of our invention by the apparatus illustratedv in the accompanying drawings, in which- Figure 1 is a side elevation of our invention Fig. 2 is a vertical section through the approximate central portion of the apparatus;

Fig. 3 is of Fig. 2;

Fig. 4 is a horizontal section on line 4-4 of Fig. 2; and 0 Fig. 5 is a detail enlarged sectional view on line 5-5 of Fig. 3.

Like characters of reference designate like elements in each of the several views.

Referring to the accompanying drawings, we provide a cleaning tank T in which the fabrics to be cleaned are placed and with which a clean solvent pipe 19 communicates, said pipe 19 also communicating with the upper portion of the small caustic removing tank 24, this tank being aranged in the main or large tank C which holds the clarifying solution. The receiving tank C consists of the main tank 6 having the tapered bottom pori ion T which opens into the top of small tank l, which latter tank is provided with outlet. pipe and valve 2. Opening out of the holtom of fabric cleaning tank T is a pipe 2O which communicates with the pump P which pumps the solutionwhich has been used through pipe 2l and discharges it through the four-way nozzle or agitator 3 which is provided with perforations 4 and which opens into the bottom portion of bottom tank 1, where the tluid'is agitated by a horizontal section on line 3-3 contact with aplurality of baiiie plates 5 radiating from the sides of this tank and disposed ,vertically as shown in Fig. 2. The annular extension 8 ofthe tapering wall 7 which projects into the upper portion of tank 1 lalso functions as al baffle member to increase the agitation of the solution before it passes upward through opening 9 into the upper main tank 6.

We provide a conical dome 10 in tank 6, this dome being provided with a series of apertures 12 arranged near its base; and also being provided with a vertical air vent 13 opening out of its apex and extending to the top of tank 6 and through'cover 36,

as shown in Fig. 2. An annular space 11 is provided between the bottom edge of dome 10 and the vertical wall of tank 6. The filtering tank 14 is providedwith a filtering element 15 extendin horizontally across its upper portion just low the point where pipe 19 opens into this tank. This filtering element consists of a plurality of wire mesh members 16 and cloth and cotton members 17, alternately arranged. `Filtering element 15 is positioned immediately below opening 18 in which the end of pipe 19 is mounted. Pipe 19 is provided with a suitable si ht glass 41. Similarl pipe 2() is provi ed with a suitable sig t glass 42. Pipe 20 is also provided with a hand-operated valve V. Opening into pipe 20 is a vertical filling pipe 43 having afvalve 44 arrangedin it, this pipe 43 terminating in a suitable funnel 45. The main tank 6 is also provided with a'sight glass 35, and in addition with a glass gauge 38 projecting above the tank as shown in Figs. 1 and 2.

Mounted on the smaller tank wall 24, as shown in Fig. 2 is a downwardly-slanting balile plate 26 which extends nearly, but not quite to the opposite wall of the tank, while mounted ou the opposite walls are spaced baille plates 25 slanti'ng upwardly in parallel relation to bafiie 26 and extending nearly but not quite to wall 24. We provide faucets. 27 opening just above the respective battle plates 25 and the bottom inclined wall of tank 24.

Arranged in tank 6 as Shown in Fig. 2 we provide a pipe 28, terminating in a funnel 29, the top of which is even with the surface of the liquid contents of tank 6. -Pipe 28 has a slaiiting extension portion 30 which terminates in the nozzle 31 which opens into the bottom of tank 24. We' also provide a Iand nozzle 3 into tank 1, thus l6 We provide' :an annular steam pipe 39 having spaced openings 40. The pipe 39 is in comlnunication with pipe 46 which is connected with some suitable source of sup,- ply 'of steam which is' used to clean the bottom of the tank and heat the fluid.

In operating our invention, the garments or fabrics to be cleaned are placed in the cleaning tank T where they are `Wa'shed in gasoline :and soaked for. a time. Then the outlet valve V is opened and the dirty solution is pumped by means of pump P through pipes and 21 and nozzle 3 into the bottom of small tank 1. rllhe settling solution is poured into funnel 45 andwthrough pipe 43 into pipe 20, the contents of which are pumped with some force through pipes 2l mixing the solvent, the mixin process being further aided by the plurality of radial baflle plates 5 andthe annular baffle extension 8. The solvent S passes upward through opening 9 and spreads out over the conical bottom wall 7 of main tank 6, also encountering the air dome 10, as indicated by the arrows in Fig. 2 of the drawings, all the air that may be in the solvent being permitted to esca e through the air vent 13 at theapex of tiome 10. rDhesolution flows through funnel 29, `,pipe-28,` extension pipe and nozzle. 31 into tank 24 where it flows through water and around the series of

baffle plates

25, 26 and 25, and upward through filtering element 15 to pipe 19 through which it returns to the cleaning tank T in clarified condition ready for use again in cleaning the clothes or fabrics that are in this tank for the purpose of `being cleaned.

The solid top 36 extending from one wall ot' the large tank over to the wall 14 of the smaller tank, and the top 37 of the smaller tank provide an etiicient coverl releasably attached as shown and reduces fire hazard.

If, for any reason,the filter 15 becomes clogged and will not Iallow the solvent to pass through into pipe 19 and to the cleaning tank T, the solvent will rise in the sight glass 38, thus warning the operator.

The openings 40 in the annular pipe 39 point downward so that steam admitted through pipe 39 will greatly facilitate the cleaning process, washing down any foreign substance which may have collected. The various sight glasses shown in the drawings `in the solution tank are for the obvious purpose of allowing the operator to see the height and condition of the solvent.

The two-way valve 32, shown in detail in Figs. 5 and 3,. affords the o erator control of the solvent,.as he may irect it either through pi e 34 into the small tank directl under the lter 15er may divert it throng pipe 30l and nozzle 31 to the bottom of tank l 24 letting the operatorV usev the clear water wash which takes'place in that part of the smaller tank indicated as 24vin Fig. 2 of the dra-wings. This section of the small tank is filled with clear water. The solvent after being cleaned as heretofore described, rises to the top-of the large tank 6, flows through the pipe 28 and extension 30 to the bottom of the small tank 24 and is sprayed into the bottom compartment through the nozzle 31. Being lighter than water it flows upward past the several baille plates until it reaches the top of tank section 34 where the slanting wall 23 permits it. to spread out before it flows through the filter land back thereafter into the cleaning tank. By these several steps we not only produce a cleaner solvent but have eliminated: the possible chance of any free caustic remaining in the solvent. The faucets 27 permit of convenient cleaning of the tank at any timesuch cleaning is needed.

The process described makes it'v ossibleL to save a lar percentage of thev c eaning solvent. It a so makes it possible to -clean rough and fine fabrics simultaneouslyl with satisfactory results in both cases.

What we claim is: 1. In an apparatus for clarifying the vsolvent used 1n cleaning fabrics, the combination of a cleaning tank in which the fabrics are placed, a solution tank to which a solution for clarifying solvent is supplied, a conduit leading from the cleaning tank to the solution tank, means for forcing the' solvent fronr the cleaning tank into and through the solution tank, a second tank into whiclrthe solution tank discharges the mixture, filtering means arranged in the upper portion of said tank last named, and a con duit arranged to conduct .the clean solvent after it has'passed through the filtering means back to the cleaning tank in which the fabrics are placed for cleaning.
