My invention relatcs to decatizing and more particularly to decatizing cylinders of cloth treating machines or the like.

Heretofore, it has been the practice to employ machines wherein the decatizing cylinders are of a length corresponding approximately to the width of the cloth to be treated. Inasm'uch as various widths of cloth are often treated in one establishment, it necessitates the establishment being equipped with a number of machines having cylinders of lengths corresponding approximately to the width of the cloth for the reason that it is not practical to treat a relatively narrow width of cloth by the employment of a relatively long cylinder and its correspondingly wide blanket because the margins of the blanket would extend beyond the edges of the cloth and thus absorb and become saturated by moisture produced by the condensation of steam. When the margins of the blanket are thus moisturized, the

, '6 Claims. (Cl.68--8) cloth being treated tends to absorb the moisture' in a manner wherein the cloth becomes spotted or water-marked and thus damaged. Obviously, it is impractical to treat cloth of a width' greater than the length of the cylinder and the width of the blanket. Inasmuch as the machines are quite expensive, it will be appreciated that quite an investment is necessary to provide a number of machines with different length cylinders in order to have available, in one establishment,

means for treating cloth irrespective of the width thereof.

My invention overcomes the necessity of-equipping an establishment with machines having cylinders of lengths for'accommodating the various sizes of cloth, it being one of the objects ofmy invention to provide decatizing means which is so constructed and arranged that various sizes of cloth may be treated thereby without danger of the 'aforementioned damage.

' Another object of my' invention is to provide vide decatizing means including a cylinder having a plurality of cloth treating -zones dened and rendered efiective by compartments within the 2 cylinder together with means for rendering the compartments efiective in a selected manner.

Another importantobject of my invention is to provide means of the foregoing described character which is simple in construction, durable in use, eficient in operation and economical in manufacture.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings romwhich the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like refera ence characters designate like parts throughout the several views:

Figure 1 is a diagrammatic View illustrating textile treating apparatus having my invention incorporated therein. p

Figure 2 is a longitudinal sectional view, partly in elevation, of the decatizing cylinder constructed in accordance with my invention.

Figure 3 is a sectional view taken on the line `3--3' of Figure 2.

Figure 4 is a sectional View taken on the line 4-4 of, Figure 2.

Figure 5 is a sectional View taken on the line 5--5 of Figure 2.

Figure 6 is a detail sectional view taken on the line 6--6 of Figure 2.

In practicing my invention, as diagrammatically illustrated in Figure 1 of the drawings, I provide'a decatizing machine or apparatus having a decatizingcylinder 5, cloth loading and unloading rolls 6 and 1, guide and blanket straightener rollers 8 and 9, and a ternary of blanket supply rolls !0, and !2, respectively. The rolls 6 and 1 are disposed on one side of the cylinder 5 while the rolls !0, l! and !2 are disposed on the opposite side with the blanket straightener roller 9 being arranged subjacent the cylinder 5.

The decatizing cylinder 5 comprises a hollow cylindriform body having a circumferential wall !4 provided with perforations !5 throughout its length and circumference and with sinistral and dextral end walls !6 and !1, respectively. The body is also provided interiorly with a pair of spaced partitions or walls !B and !9, thewalls !6, !8, !9 and !1 defining sinistral end, intermediate and dextral end compartments 20, 2!

and 22, respectively. The circumferential wall !4 is provided with a ternary of cloth treating zones 24, 25 and 26 defined by the compartments 2, 21 and 22, the widths of the zones 24, 25 and 28, in the present instance being approximately twelve, forty-two and twelve inches, respectively.

The end walls 55 and l'l are centrally mounted for rotation upon stationary bearings 21 and 28 with the latter having extending therethrough a -pair of conduits 29 and 30, respectively. The inner ends of the conduits 29 and 30 communicate with the compartments -2'I 'ana 22, respectively, with the innei' end of the condui't 29 extending through the wall [9 and having sealing engagement therewith by means of a packin'g joint J to permit rotation of the wall 13 ;relative to the conduit 29. The conduits 29 and 30 have extending therethrough siphon tub e's `3 ah-a 32 which have their inner ends rght aI-gularly ben t and terminating in proximity to the bottom of the compartments 2| and 22, respectivel'y. 'The hearing 21 is provided with a conduit 33 comf"hthe'compartment 20,'theonduit g prvae'd with a `'sli phon *tube 34 having er 'end right-angularly 'bent and terminatm' proximity 'to the bottom of the compart- ^2o in the same mann-er a's 'th'e tubes 31 and '32. The innerends of the cn'd-uts 30 'and' 33 are provided with laterally extending =branches or sections 3`5whi1e'the innermost'radi'al face of the walli'i 'is 'formd With radiany EXtdng s'l'vei's 36 jc'mmumcatin with the Conduit 29 whereby ste-am is introduce-'d 'into the 'compartin dr suctioh'es'tablished thefein ly 'negative pressu re as 'hrinafter more fully described.

about the zones 24, 25 and 26. Obv iously, a length of relatively narrow material of approximately twelve inches may be treated by disposing the same, together with a suitableblanket, about the zone 24 or 26. When the material to be treated is thus disposed about the zone or zones, the compartments, defining the zones thus being utilized are supplied withsteam.

From the foregoing, "it "will be appar'ent that my inventionprovids means wher'eby textile material of various widths may be treated by a single cylinder, the steam being supplied to the material through a, selected compartment or compartments according to the width of the material to 'be 'treated While in the present instance, I have disclosed my invention as being con- 'stfuc'tdin 'a 'marner to accommodate material of be understood that the cylinder may be divided into a greater'or -lesser number ef compartments 'tha-n that disc'losed and equipped with steam 'supplying and removing conduits and-siphonn tubes for each of the compartments provided.
