. To all 'whom it may concern:

Be it known that FREDERICK H. DANiELL, deceased, 4-forrnerly a citizen of the United States, residing at Franklin, in the county of Merrimac and State of New Hampshire,

did invent certain new and useful Impiyements in Cop-Tubes, of which the follow ng is a specification. l

My invention relates to improvements in and retainingyarn, or similar material, during the process of washing, or other like treatment, and in transferring processes related to the manufacture and uses of the material.

' are placed end for The object of my invention is to provide aporous, non-collapsible tube, on which the yarn may be wound in the form of a hollow cylinder, cone or ball, in such manner as to be retained. in its original conformation to be submitted to dyeing or similar processes, and -from which the yarn may be subsequently unwound.

A further andl most important feature of my improvement is, to yprovide a cop tube which-will be yieldingly contractible in the,

direction of its axis, so that when the cops end and packed in the dyeing chamber, they may be firmly pressed together vto form one continuous 'and compact mass of yarn with a central opening from the following description of the method of dyeing; but I do not herein claim as my invention, the process or method, the same being the subject matter of aseparate application, `Serial No. 427,379, filed April In `dyeing vyarn in the cop or package, it is the preferred practice to pump the liquor into the tube by pressure, so as\'to force it radially out-ward through theivwalls of the tube to penetrate and permeate the yarn mordanting, bleaching,`

'connected at one end wit mass whichsurrounds the tube. In some cases, to insure complete saturation, it is advantageous to also employ the reverse process of forcing the liquor back again through the co'p from the out-side, using the tube as a channel forthe outflow. In other cases the liquor is forced from the tube radially outward through the package and then drawn back again by suction.

The most practicable and eflicient Way of dyeing the cops in quantities is to arrange them in groups, with the ends of thecops abutting and their tubes alining to form a channel for the liquor. A convenient method is to provide a pipe of a diameter to tit the internal diameter of the tubes and perforated with' openings for the outflow of the liquor. Any convenient number of 'cops might be placed on the pi e, the latter being the inlet of the dyeing vessel or vat, and having its other end closed to prevent escape of the liquor, through the cops. It will be obvious that with this'arrangement, unless the cops are heldfirmly against each other, there will b'e a tendency for the sistance to its outflow at these points vthan where it must be forced through the yarn.

To prevent this, it has been'found expedient in practice 'to press 'thecops firmly together; as for instance, by the use of flanges or plates adapted to bear on the ends of the cops and arranged to be adjustable along the pipe which .supports the cop. Itwill be. ps are placed understood that two or more co on the liquordistributing pipe and the fianges set up against their outer ends. two flanges are forced toward each other to press thek cops tightly together, and then secured in this position by means of collars or other devices. "It will be realized that a necessary requisite for this arran ement is a provision for allowing the cop tu e to conthrough the package The PATENT oEEI-CE.l

except liquor to escape between the ends of the' cops, there being less re-` tract in the direction of its axis, in order `that it may not resist the end pressure on the cops. It is with this purpose in view that I have devised the followingdescribed novel cop tube.

My invention is shown in the accompanying drawings, in which:'-

Figure 1, isa sectional view lof a cylindrical cop, showing my improved tube applied thereto; Fig. 2, a sectional view of a conical cop, showing how the tube mightt be adapted by a helical coil of wire, or other material, c.

The sleeve may be of fabric or webbing, either knitted, netted, woven, or braided, and preferably of reticulated character, having meshes suificientlylarge to permit a free circulation of the liquor or gas.A The supporting coil c may be either of round or flat wire, and of such material as will not be disintegrated or corroded by the action of the dyeing chemicals.

As shown in Fig. 1, the wire .is coiled openly so as to allow the coils to close up, to permit contraction of the co tube' C along its axis. The coils act to distend the sleeve in tubular shape, to form a cylindrical support for the cop, which c'an be held rigidly on the winding spindle and which will not collapse -from constriction of the windingwhen the tube is withdrawn from its mandrel. -This feature is very important, because it is necessary that the cop be retained in i-ts original conformation inorder that the yarn may be unwound freely to deliver at high speed in the processes for which it is prepared by the dyeing. If the,

cop were allowed to collapse, th'ecoils of winding would become misplaced and tangled, and the delivery of the yarn would be impeded and cause imperfections in the product to 'which the yarn is supplied. It will be obvious that the wire coils must not be spaced too far apart, or -the windings of yarn 'will cause the sleeve b to sag in between the coils c, and interfere with the delivery of the yarn in unwinding.

The referable 'form of cops for use in the dyeing or other similar processes is that of a cylinder, as shown in Fig. 1, because -the mass of yarn is more evenly disposed aroundl the tube than in aconeor ball. It

c has also been vfound preferable to have the opening in the cop of considerable diameter,

about one third the whole diameter ofthe package, s`o that a comparatively large sur- 'face of the yarn is exposed to the dyeing liquor, /to facilitate its penetration .of `the The cop tube C is preferably longer than the package and projects slightly beyond the ends of the latter, so thatv yarn will not fall down over 'the ends of the'tube; but when the packages are placed end for end and compressed, the supporting coil c of `the tube is contracted, and the end coils forced within the ends of the cop, so as not to sepa-l rate one cop from another. The shortening is pointed out that the coils c contract independently of, and draw up Within the sleeveb, Without shortening the length of mass, but when the wire coils are compressed within the confines of the cop, theprojectcase of delivery ofthe yarn in unwinding. The cop tube E in this case isl of conical form, the coils of wire e gradually increas- 'ing in diameter from oneend tothe other, and the sleeve f is fashioned to fit this form. In arranging a pluralityI of ^these cops for dyeing, the cops will be disposed with the of the next come, and the small end of this cone abutting the small end of the next cone, and so on.l The liquor-distributing form of cop, there accomplishing thismade in sections Vof conical form to cop tube and adapted Lto be coupled together after the cops had been placed on the pipe sections; or a straight pipe might be used,

The pipe might be in the small end of the tube'. In this latter case, it would be,l necessary to emplby some l form of supporting device for the larger end of the cop tube, such, for instance, as a ring or flange, bored to receive the pipe and Lfitted to the larger opening in thecop tube. l.These rings wo d, of course, be slipped on tothe pipe at being arranged on the pipe.

Iig.` 3 'shows a cop of spherical'v formation, butA having flattened ends, andthis ,form of package could be handled in the same way as cylindrical cops; that is, arranged with the fiat ends abutting.

It will be understood that my invention geous for some purposes on account of greater pipe must be especially `adapted for this being several ways of e same time the cops were v approximately 1 of the cop tube as a whole is effected by Y the closing together of the wire coils, but it said sleeve. -In other words, the sleeve b does not shift its position in relation to the yarn ing-ends of tlie sleeve simply collapse and l base end of one cone abutting the base end fit each l of a diameter not greater than the opening is a cop tube, and does not comprehend the form or character of cop used thereon, but I have shown several forms of packages for Which-the tube is adapted. 'I do not limit myself to any one form of cop, nor to any particular method of Winding; the preferable method of Winding, however, being by what is kown as the universal, or V Wind. This system gives absolute regularity in the disposition or la-y of the coils of yarn, and, therefore, the most uniform density throughout the yarn mass. In this system of Winding, the coils can be spaced accurately, any desired distance apart, so that the vcop can be made more orless porous as desired, and the dye liquor Will penetrate the Whole mass uniformly. 1

I am aware that cop tubes for dyeing have been heretofore made of flexible fabric, and in some cases the fabric has been stiffened With sizing or starch, to retain its tubular form during the Winding. It Will be evident, however, that when the cop is subjected to the action of the dyeing liquor, -the sizing Will become mo-istened and lose its sti'tfening qualities, so that the tube Will collapse and nal form.

In the present invention, I have devised a novel method of combining the fabric tube \\vith means for distending and supporting it in tubular form, to sustain the cops and resist the constriction of the `yarn mass Wound upon the tube, and to provide for longitudinal contraction of the tube When the cops are pressed together end for end.

It is evident that other means for supporting the sleeve might be provided, such as rings spaced at intervals along its interior, or. other similar arrangements which Wouldv fall within Ithe scope of this invention. Therefore, I do not limit myself to the exact form of 4structure shown,- but vWhat I claim is l.
