Claims.

My invention particularly relates to improved forms of inserts adaptable for mounting fine filamentous rayon thread in annular package form, such as cakes, wound spools, wound bobbins, and other annular packages of symmetrical or balanced formation, for the purpose of liquid treating the thread. The rayon thread is collected in such annular package forms by spinning, machines from the precipitating bath in which the rayon filaments are set up. The rayon thread as so collected comprises a comparatively large number of filaments which are twisted as some forms of packages are being collected and are collected untwisted in other forms of packages. My invention is an improvement upon the forms of package inserts shown, described and claimed in my pending application, Serial No. 724,114.

The treatments to which the rayon packages are subjected by my improved apparatus are those to which the rayon is necessarily subjected, before the. precipitated and package-collected thread can be considered a final product ready for the market, such as various water washings desulphurizing, bleaching, oiling, szing, dyeing, drying and other purifying and finishing operations. For purposesof illustration, I show in the accompanying drawing and herein describe two forms of my improved insert which serve to support a cake oi rayon while the same is being subjected to the above-mentioned operations.

The objects of the invention are to effect the aforesaid operations in a thorough manner and economically, and without breaking or otherwise materially damaging the thread, while at the same time preventing the creation of any immobile areas in any portion of the package, or unequal strains in different portions of the package, either during the liquid treatments or during the drying of the package, which immobile areas and strains result in a non-uniform dyeing of the thread of the package. The obviating of the creation, of immobile areas and strained conditions in the package produces even shrinkage during the drying of the package. This even shrinkage is obtained by even one drying operation, thereby obviating the necessity of rewetting the package and again. drying it in order to improve the uniform shrinkage factor. Furthermore, if some portions of the package dry in an immobile condition, or have strains set up therein by some of the purifying and drying operations, antecedently to the dyeing thereof, different portions of the thread in the package then have different reflective indexes and give different color reactions or have barred effects when the thread is dyed, resulting in a thread of non-uniform color.

Primarily, my improved insert effects the loosening up of the package, when treating the latter in its initial collected form, so as to provide for all parts of the package their respective natural scopes of free play, relative to other parts of the package, thus effecting a natural alteration of the relative positions of all the thread strands comprising the package. The purification of the package and the other, treatments thereof are carried out without unduly impairing the tenacity and elasticity of the thread required for later handling and processing or use, and without setting up local tension areas or non: uniform strains.

In effecting the aforesaid advantage, my improved inserts permit the pulsating of the package body by means of treating liquid in that the package, while mounted upon. the insert, is free to move to a predetermined extentin, and under the action of, the treating liquid. The improved inserts provide for so mounting the package that different portions thereof move or pulsate differently under the action of the treating liquid; specifically, spaced transverse portions of the package react differently than the package portions intermediate said spaced transverse portions.

Improved processes of liquid-treating rayon packages, and apparatus therefor, are shown, described and claimed in my pending application, Serial No. 724,113, and the improved inserts of the instant application are adaptable for use in working such processes. It is'designed in such improved processes that the direction of flow of i the treating liquid shall be, or at least may be,

periodically reversed, thus to pass the liquid alternately in both directions through the package body, from inside out and outside in, or at least the treating liquid penetrates the package body and tends to pass through alternately in both directions. The treating liquid is passed through the package body under any desired practicable pressure so as thereby to control to an extent the character of the treatment and the character and amount of package movement and pulsation, and the pressure may be maintained uniform or may be varied. Although the range of practicable pressures is considerable, particularly by reason of the different effects of dilierent treating liquids, I preferably use a nominal pressure of from one to two pounds. My, improved inserts are of split formation, so as to provide for the convenient insertion thereof within the rayon package, in order to mount the package thereon for treatment without damaging the thread of the package, but the liquid pressures used in the liquid treatments are not great enough to materially expand or compress the split inserts, so that the latter provide a substantially rigid support of constant dimension during the liquid treatments. Furthermore, as clearly shown and described in said pending application, Serial No.

724,113, a plurality of inserts are tightly locked together in a vertical tier, so as to hold the inserts rigid during the liquid treatments, with a rayon package mounted for treatment on each one of the inserts.

When the treating liquid passes from without the tubular package through the body thereof and into the interior of the package, my improved .inserts provide for a deforming of the package by permitting portions thereof to move inwardly a predetermined distance under the pressure of the treating liquid, so as to loosen up the package to a degree and permit an altering of the positions of the strandsor different portions of the thread comprising the package. When the treating liquid passes from within the package outwardly through the body thereof, the deformed package portions are moved back into their original collected form, or tend so to move, so that these package portions are pulsated or have to-and-fro movements under the action of the reversible liquid flow. It is. well understood by those skilled in the art, that rayon packages of the character herein described are spun so that the strands thereof prevent any substantial enlargement of the package perimeter. Therefore, the pressure of the treating liquid from within the package outwardly, under any pressures practicably usable, do not bulge or deform the package outwardly so as to increase its perimeter to any material extent. package which are not moved inwardly by liquid passed inwardly of the package body are adjusted somewhat outwardly during such treatment, as clearly shown in the accompanying drawing and as will be hereinafter fully described. The improvements in the forms of inserts shown, describedv and claimed .in the instant application, over those shown, described and claimed in my said pending application, Serial No. 724,114, consist in means for more uniformly liquid treating the rayon package, specifically, these improvements comprise means for permitting the passage of the liquid through the insert. elements which define the several package portions that are difierently deformed by the treating liquid. These elements, as shown in said application, Serial No. 724,114, consist of insert bars, bobbin plates, etc., between each adjacent two of which are provided elongated lengthwise openings through which transversely spaced portions of the package defined by such bars and plates are pulsated. Radially exterior of these bars or plates are certain package areas which do not receive efficient and satisfactory liquid treatment. Therefore, I have devised forms of inserts shown and described in theinstant application which provide for the passage of liquid through the bodies of the spaced bars and plates whereby to permit the thorough liquid treatment of the rayon package areas immediately exterior of such bars and plates.

The annexed drawing and the following description set forth in detail certain means exemplifying my improved forms of package in- However, those portions of the is collected by the spinning machine or, if it has been deformed by a treating liquid passed therethrough previously from without the package inwardly, in the form in which it re-establishes itself or tends to be so re-established, when the treating liquid ispassed through the cake from within outwardly;

Figure 4 is a view, on an enlarged scale, of a portion of the showing of Figure 1; v

Figure 5 is a perspective view of a second form of insert embodying my improvements;

Figure 6 is a transverse section of the insert shown in Figure 5 with a cake mounted thereon for liquid treatment, this view showing the cake in the form in which it is collected by the spinning machine, or, if it has been treated by a liquid passed therethrough previously from without inwardly, in the form in which it re-establishes itself, or tends to re-establish itself, when the treating liquid is passed therethrough from within outwardly; and

Figure '7 is a view similar to Figure 6 but showing the forms assumed by the different portions of the package body, or the forms which they tend to assume, when the treating liquid is passed through the package from without inwardly. 7

Both forms of improved inserts shown and described provide for efiicient and satisfactory liquid treatment of those package areas radially exterior of the spaced bars and plates or equivalent means between adjacent deformable areas, but the claims of this application are directed to that form of improved insert shown in Figures 1 to 4.

Referring to the annexed drawing in which the same parts are indicated by the same re-- spective numbers in the different views, and particularly referring to Figures 1-4,. an insert l consists of an annular shell having a multiplicity of ports 2 through the wall thereof, said ports preferably being arranged in a series of lengthwise rows and a series. of transverse rows, as clearly shown in Figure 1. These ports 2 provide means for liquid communication between the interior and exterior of the shell body. Secured to the exterior surface of the insert by rivets d are a plurality of non-corrosive bars 3. preferably spaced longitudinal outwardly extended hard rubber bars. These spaced bars 3 provide spaced elongated lengthwise openings 8 between the adjacent bars 3 when a cake package I is mounted upon the bars 3. When the treating liquid is passed through the package 7 from without inwardly the cake portions 9 between the respective adjacent bars It are moved in wardly until they contact with the portions H of the insert body. The portions ill of the cake body immediately exteriorly of the bars 3 cannot be moved inwardly but, in fact, adjust themselves slightly outwardly, as indicated by the areas I I, Figure 3. When the treating liquid is passed through the package body I from within outwardly, the cake portions tend to re-establish themselves in the position shown in Figure 2. During the early stages of the liquid N treatment, the time or pressure of application thereof, or the density of the package body, may be such, as not to permit entire penetration of the package body I by the treating liquid, so that the package portions 9 will only tend toward the positions shown therefor in Figures 2 and 3,

and the package portions II] likewise.

In order that the package areas I may receive liquid treatment uniformly with the package portions 9, I provide the bars 3 with ports 5 which have liquid communication with the interior of the insert I and with the package body areas Ill. Preferably, I arrange the ports 5 to register with all of the ports in the adjacently lengthwise row of insert ports 2. That is, the ports 5 of each of the bars 3 register with all of the ports of one lengthwise row of ports 2 and with one of the ports of each transverse row of ports 2. Furthermore, I preferably enlarge the outer ends of the ports 5 so as to provide ready and thorough distribution of the liquid from theports 5 into the package bodies 'I' when the liquid flow is from within outwardly and so as readily and thoroughly to direct the liquid flow from the pack-- age body I into the ports 5'when the direction of the liquid flow is from without inwardly.

The several insert portions I2 formstops limiting the amount of inward movements of the cake portions .9.

By the means described, a thorough liquid.

treatment of the package portions I9 is secured, together with the thorough treatment of the package portions 9. i

In Figures 5, 6, and '7, I show a form of insert, preferably of non-corrosive metal, which is polygonal in cross-section and by the use of which are effected the advantageous liquid treatments contacts the corners I91 of the insert, thus leave ing openings 29 between each two adjacent corners I9, into which openings 29 the spaced pore tions 2| of the package I5' are forced by the pressure of a treating liquidpassed through the package from without inwardly, as clearly indicated in Figure 7, the areas 22 of the package I5,

which are adjacently exterior of the corners I9,

, being forced slightly outwardly during such ac- I tion, as indicated by the areas 24, Figure '7. The

several plane insert portions 23 form stops limiting the amount of inward movements of the package portions 2|. When the treating liquid is passed through the package I5 from within the insert I6, the package I5 tends to assume its original collectedfo-rm, as clearly indicated in Figure 6. The insert I6 is formed with a multiplicity of ports II, which ports are preferably arranged in a series of transverse rows and a series of lengthwise rows, Figure 5. In order thatthe areas 22 of the package I5 may be efficiently liquid treated, as well as the spaced comparatively large areas 2i, certain of the ports I! are disposed in the angles I9 of the insert, as indicated by the ports I8. Preferably, one of the lengthwise rows ofports I1 is intersected by each angle I9 of the insert I5, and eachangle I9 also intersects one portof each of thetransverse rows of ports. I'I.

By the means described, a thorough liquid treatment of the package portions 22 is secured, together with the thorough treatment of the package portions 2L The pulsating of the rayon package during liquid-treatment which is occasioned by the use of my improved package inserts, and the consequent loosening-up and porosity of the package, give all portions of the latter full opportunity to contract when drying, in accordance with their several tendencies, without occasioning any strain in any portion of the package. By pulsating I mean theinwardly and outwardly to and fro movements made by the package and the constituent parts thereof during the liquid-treatment of the package upon. my improved inserts.
