APPARATUS FOR PACKAGE DYEING.

Application filed October 6. 1924. Serial No. 741,792. 7

Clinton, in the county of Worcester and State of Massachusetts, have invented cerparatus for Package Dyeing,

tain new and useful Improvements in Apof which the following is a specification.

This invention relates to apparatus for package dyeing, and has particularl to do with the dyeing or fluid treatment 0 a plurality of packages of yarn and the like in which the previously wound, cylindrical packages are mounted or assembled upon .aperforated pipe passing through the holes in the centers of the same, and through which pipe the dye, other treating liquor or gas, is forced so that it passes radially and outwardly from the pipe into the surrounding package or packages of yarn.

At the present time, there are various ways of accomplishing this result,-for example in one current practice, the packages are wound upon plain hollow tubes. Following the winding, the tubes are removed from the respective packages and several of the latter mounted upon a long fluted liquor spindle and pressed from the ends and held together during the dyeing. In so doing, it is necessary to remove the tubes from the packages before placing them upon the liquor spindle because a winding or. supporting center tube must extend a fraction of an inch (for example, beyond the ends of the yarn package which is wound upon it in order that the winding operation may be performed properly, and the turns of yarn not slip off the ends of the tube. Thus, if a series of such packages with the tubes therein were placed upon the dye pipe, it would be impossible, to compress the packages together so as to prevent the dye liquor from issuing between the adjacent packages because of the projecting ends of the winding tubes. Another objection to'this manner of accomplishing the desired result, aside from extra steps it entails, is that the removal and replacement of the hollow winding tube frequently displaces or breaks the innermost coils of the am in the package and thus causes waste. 11 order to obviate this last difiiculty, the package is commonly wound upon a supapparatus for package porting center of variable length, for example, upon a compressible spirally wound spring of approximately tubular shape which is encased in a tube or stocking, of cloth. Such a stocking covered spring, however, has a very short useful life, is difficult to handle, and often involves a waste of yarn. dinal compressibility, the spring tubular member does not interfere with the uniform and even compression of the package which is so essential to the dyeing operation but its wrinkled and irregular outer surface and stocking ends interfere with the winding and unwinding operations, espec1al1y the latter, because the yarn, in ordinary practice, is pulled off in the direction of the length or axis of the package.

The object of this invention is dyeing which obviates the objections above referred to and in which the yarn is wound upon a supporting center, and preferably upon a perfectly smooth, straight, round, metal perforated tube on which it remains undisturbed throughout quent unwinding of the package or, in other words, the yarn is handled. throughout on the best possible tube for winding and unwinding and at no sacrifice of efliciency in dyeing or in the quality of the product.

The apparatus of this invention consists of a series of'packages wound upon suitable supporting centers, assembled and. pressed together upon a perforated or other similarly functioning dye or liquor pipe and having interposed between said packages and thick enough to terial or construction,

be uniformly allow the yarn package to compressed and pushed back of the tubes as the packages are compressed, and yet allow sufficient space between the ends of the tubes so that they do not bear upon each other and interfere withthe compression of the packages,thus the pressure is all upon the yarn and the interposed rubber pads or wa shers. A refinement of the above consists in providing perforated washers, (though plain Washers may be used throughout) so' that the dye or liquor may freely circulate direct from package to package but.still be prevented from escaping outfrom the ends- By reason of its longituto provide the winding, dyeing. and subsesuitable washers, preferably of yieldable mawardly between the washer and its adjacent packages, and also to insure even dyeing at the ends of the packages.

In the drawings Fig. 1 is an elevation, partly in section, showing one package and portions of adjacent packages mounted upon a dye or liquor pipe. with washers interposed between said packages; and

Fig. 2 is a perspective view (slightly reduced) of a suitable perforated washer.

Referring to the drawings in which like numerals represent like parts .2 designates generally a portion of the liquor pipe having holes 3 in the walls thereof, upon which the packages 4 on their tubes 6 are assembled and aligned, the tubes 6 having holes or perforations 7 in the walls thereof. Various other supporting centers which allow a free circulation of the liquor may be substituted for the tubeshere shown and described. Similarly the liquor pipe may be of a different type, or even entirely omitted provided the packages are so held or aligned that fluid can be circulated through their central openings and to the packages without interfering with the oints between the packages.

8, 8 designate washers interposed between said packages having a central opening 12 of a slightly larger diameter than the external diameters of the Winding tubes 6, and holes 10 extending therethrough so as to permit a free circulation of the liquor from one package to an adjacent package or packages. The washers 8 are preferably made of vulcanized rubber thick enough so thatthe ends of the tubes 6 extending beyond the ends of the packages 4 are spaced from one another as before mentioned, and this even though the packages are compressed longitudinally to a considerable extent, or more than is shown in Fig. 1. Inasmuch as the yarn packages are themselves compressible and of such a character as to form a fairly (liquid and gas) tight joint when pressed against a suitable surface, it is not essential that the yieldable rubber washers here shown and described be employed, and it is contemplated that washers of other materials and constructions may also be used. The washers 8 should be of slightly larger diameter than the adjacent yarn packages so that the space between the packages 4 is entirely 'filled up. It is obvious that one more washer than the number of packages will be required in order that each package, including the end packages of the assembled group (this I prefer), may be held compressed between two washers and provide liquid tight joints at the ends of all of the packages so that the direct escape of the liquor is prevented,thus all of the liquor or gas that does escape from the assembled packages must have passed through them.

From the foregoing it will be apparent to those skilled in the art, that the use of this invention results in a marked efficiency and saving of time, labor, and material in the winding, dyeing, and unwinding as over the present practices. As to the winding,the separate operations and length of time required to place, wind, and remove a supporting center from a winding machine are reduced to a minimum, and a proper even wind assured. The packages are easily placed, evenly compressed and tightly joined for the fluid treatment. The removal of the packages is readily accomplished, and after simply drying they are in perfect condition for a continuous, rapid, complete unwinding.

In my use of the word into in the following claims I contemplate that the fluid may in some cases, if desired, be circulated into the packages from their exteriors and exhausted from their interiors.

Having described my invention, what I wash to claim and secure by Letters Patent 1s 2- 1. In apparatus of the class described, a series of packages wound upon suitable supporting centers adapted to permit the circulation of fluid into said packages, and rubher Washers interposed between said packages adapted to permit the same to be longitudinally compressed.

2. In apparatus of the class described, a series of packages wound upon suitable supporting centers adapted to permit the circulation of fluid into said packages, rubber washers interposed between said packages adapted to permit the same to tbe longitudinally compressed, and means adapted to keep said packages substantially axially aligned.

3. In apparatus of the class described, a series of packages Wound upon suitable supporting centers adapted to permit the circulation of fluid into said packages, and yieldable spacing means interposed between said packages adapted to permit the same to be longitudinally compressed.

In apparatus of the class described, a series of packages Wound upon suitable supporting centers adapted to permit the circulation of fluid into said packages, yieldable spacing means interposed between said packages adapted to permit the same to be longitudinally compressed, and means adapted to keep said packages substantially axially aligned.

5. In apparatus of the class described; a series of packages wound upon suitable supporting centers adapted to permit the circulation of fluid into said packages, yieldable perforated washers interposed between said packages adapted to permit thesame to be longitudinally compressed, and means adapted to keep said packages substantially axially aligned.
