' Fig.3 is a vertical longitudinal, section on vertical transverse section of Referring in detail to the drawings a 1 designates a cabinet-having the front wall 2, the shortened rear wall 3, the side.

walls 4 the bottom' 5 inclined as shown and and the bottom, the cabinet being supported on legs '7 Which'are extensions of angle irons whereby the corners of the structure arerei'nj forced. The cabinet is constructed prefer'-- ably'ofsheet steel and thejoints welded. V

The front and rear walls aresubstantially longer than the side walls-inthepreferred form so' tliattthe. cabinet is substantially Wider than its length from front'to back, for

purposes which will be-disclosed. r I

A division wall Sis installed as shown parallel with the sidewalls in the'pro'ce'ss of construction 7 of the cabinet, whereby" two chambers are produced in the cabinet, the first chamber 9, whichis the smaller'of the two, being designated a saponifying chamber and the second,"10 being designated a water rinse chamber. An emulsifying Or'sapOnifi cation substance is deposited in the sappnification chamber 9 the substance designatedll occupying a prescribed space inthe chamber. Atop plate 12 is providedforthe cabinetin which is a port 13 through which filtering or saponifyingmaterials may be deposited in thesaponification chamber.

Suspension of flow of fluid and pressure into the cabinet may set up suction todraw the fluid that is in the cabinet out therefrom, through the inlet, and tomeet this contingency I provide an anti-siphon valve.

A gauge glass 40 of a type which will be more particularly described elsewhere; is installed in the front wall of the vcabinet, having branches 41 and 42 respectively above and below theupper surface of the. filtering material in the saponifying chamber togive information on the heightand condition of thefluid and jmixturesin this chamber. A similar gauge device 43 is installed in the waterin the chamber. A third gauge 44 is positioned in the front wallof the cabinet adjacent the-upper portion of the rinse chamher to disclose the, heightand-condition of the cleansed fluid adjacent the point of emergence from the renovating and purifying apparatus. The gauge glasses shown; and preferably installed-are ofa type more particularly; described and ,novel' features claimed asinventiomin an application filed of j even dateherewith.

Suitable drains 45 and 46 properly valved are provided at the lower point of; each chamberfor wlthdrawal of the substances in the chambers, as desired The structure having been-provided" described, the fluid that has been used in cleaning garments or the like is delivered throughthe slottedinlet to the filtering material in the saponifying chamber. The ma terial is preferably an emulsifying agent such as an alkali which, reacting with the greasy substances; carried by the fluid, produces a soapysubstanc'e that forms awfiltering scum adjacent .the surface of the fil tering material. The liquid is physically,

filtered through this scum and theemulsifyg ing factor for withdrawal of impurities, and

1 the physical filtering factor, substantially cleanse the fluid;- The waste material gath-' ers insubstantial quantities adjacent the surface of thefiltering material and excess, accumulation ofemulsifiedj greases and oils would tend to settle downinto the filtering material and seriously hamper the passage of the fluid therethrough and prevent. contact of the fluid with the saponifying materialr It is to meet this objectionable condition that opening 34 is provided Wherethroughthe emulsified greases'and oils may bereinoved-as desired and as they: accumulate, The steam port 22 may be used to admit steam or like agent through the slotted inlet-"to soften the scum and the 'einul'si'fied materials to promote -their l withdravval through said opening 34, the steam or other cleans ng agent introduced also cleansing the filtering material to render it more efffec'tivel The water ofisteam condensed in use will ,find its natural level either; adjacent the surface; of the filtering material, from it may be withdrawn throughthe openin or at the bottom'of the chamber, from w i'ch andris conducted to thegbottomrof'theiwi ter rinse chamber and admitted from the slotted tube in a'sheet which travels in I stantially extended form through the water,

thus receiving a rinse or 'washing; whereby 5 further cleaning of the liquid is 'ac complished.- f p The fluid having been projected into the rinse chamber in the thin sheet form m ntioned, and passing through-the enters the space above the waterrjin a stream having a considerable cross section, and then travels through a considerable space. and over an appreciable lapse of time betweenthe surface of the water and the outlet from the chamber so that opportunity is given for the, settling down of light lints, silts and Water Ice solubles to the surface of the water, Where the settlings tend to remain intact The said settlings or waste 'may be removedth-rough the port 27. Such foreign matter as ,may

be captured byjthe water, and fall there through, maybe removed; and water and fiuid maybe drained out, through the drains 46 in the bottom of the rinsechamber, The structureas thus, provided and operating is particularly adaptable for use in. smallerplants wherei a compact apparatus is-desired and where more exact control' of each factor in the cleansing off-the liquid and in the movement of the liquid from machines through the renovating-process andback to the machines, are required. 1 j v lVhat I claim and desire to secure by Letters Batent is: r I 7 1'.
