j spools, etc. which supportsV prevent the deforma- Vtion of axially compressed columns of such cakes or cheeses mounted on spindles during fluid treatment of said cakes or cheeses, such as washing,

dyeing, etc.

Previously, perforated disks and tubes have vbeen employed for spacing yarn wound bobbins on spindles for their fluid treatment, but this type v'of supports easily become twisted and broken which causes ununiform penetration of the Vtreating fluid through the fibers in the column, resultl in'g in bad treating Vor dyeing.

.Also specially designed plastic supports have been used but they dissolve in caustic treating solutions 'and are not resistant to hot solutions or to dyes, and `therefore must be replaced periodically.

It is an object of this invention to produce a simple, effective, eicient and economic textile bobbin support which avoids all the disadvantages above mentioned.

Another object is to produce a bobbin support which is non-corrosive, can be used for a longer period of time, permits the treating fluid to pass easier and more uniformly through all the bers of the yarn wound on the bobbins, enables longer columns of cheeses or cakes to be employed during the treating, and prevents leaking of the treating fluids between adjacent cheeses or cakes in a column.

In accordance with this invention, the support (for bobbins strung on a spindle is made from a non-corrosive metal such as stainless steel, or the like, and comp-rises (l) an annular ring with a peripheral flange which supports the cylindrical end of a bobbin; (2) a cylindrical collar or sleeve which slides over the spindle upon which the bobbins are to be strung; and (3) a plurality of radial spokes between said ring and said collar which maintain them in spaced parallel planes and hold the end of the bobbin in said ring.

' Thus, each end of a cylindrical bobbin is fitted -into the ring flange of such a support, and for adjacent bobbins, that'is, those not at the ends of the columns but those which have two supports on adjacent ends of said aligned bobbins abutting each other, preferably have their abutting rings welded together to form a unit pair of opposed supports, the weld being continuous and preventing the treating fluids from pass- Cing between the two adjacent rings and likewise from between adjacent bobbins of yarn in the column.

In the case of cakes, which have parallel wound threads on bobbins as distinguished from bobbins which have crossed wound threads on bobbins, the supports may be provided with additionel annular rings with flanges to form annular troughs of sufficient diameter to lit over the whole ends of the cakes and thereby better prevent their deformation in the column.

The above mentioned and other features and objects of this invention and the manner of attaining them will become more apparent and the invention itself will be best understood by reference to the following description of specific embodiments of the invention taken in conjunction with the accompanying drawing, wherein:

Fig. 1 is the partial vertical section of a column of cheeses mounted on a spindle before they are compressed, the bobbins of which cheeses are fitted with the supports of this invention;

Fig. 2 is similar to Fig. l with the cheeses compresse-d on said spindle; ,Y

Fig. 3 is a vertical section of a unit pair of bobbin supports of the type shown in Figs. 1 and 2.;

Fig. 4 is an axial or end view of the bobbin support shown in Fig. 3; and

Fig. 5 is a partial vertical section of a modified form of a bobbin support having an additional annular ring for supporting the Whole end of a cake of yarn.

Referring to Figs. i and 2, there is shown how a column of cheeses le of yarn wound on porous cylindrical bobbins il may be strung on a spindle I2 and held in position on said spindle by means of the metallic supports 2S of this invention. The ends of the spindle I2 may be threaded to receive nuts i3 and is. Near one end of the spindle l2 there may be provided a shoulder l5 which may be inserted through a larger hole l1 in a hollow conduit it and then clamped in a smaller hole in the opposite side Wall of said conduit by the nut is. The aperture il is sufficiently large to permit a treating fluid from the conduit i6 to pass through it and around the spindle l2 and up the center of the column of cheeses inside the bobbins, and between the spokes 2i of the supports Zt. Thus a treating fluid, such as dye, may be forced under pressure from conduit l5 through the porous walls vof the bobbins Il to penetrate the fibers of the yarn of the cheeses l@ when said cheeses are compres-'sed on the spindle l2 between the flat rigid I8, and the outer wall of the conduit I6 eccelsal by the nut I3 as shown in Fig. 2. The supports 20 are not so long axially that they cannot permit axial compression of the cheeses, as is indicated by the space I9 in Fig. 1 between adjacent collars 22 of adjacent supports, as compared to the absence of this space in Fig. 2.

Each support 2t, see Figs. 3 and 4, comprises an annular ring 23 with an outer peripheral flange 24 parallel to the axis of the ring, producing an L-shaped radial cross-section for the ring. It is within the flange 24 and on this ring 23 that the end of a bobbon fits, as shown in Figs. l and 2. Above the ring 23 in the direction of the frange 2li there is a cylindrical collar, hub, boss or sleeve 22 having a central aperture slightly larger than the outside diameter of the spindle IZ, so that it may be easily slipped over the spindle and slid along said spindle without friction. To this sleeve type collar 22 there may be attached, or made integral therewith, equally spaced fiat spokes 2| (four shown) which extend axially and radially outwardly from the collar 22 to the ring 23 at which they are bent at right angles to the axis of the collar in the plane of the ring 23 and there integrally attached, such as by electric welding, brazing, or soldering, to the surface of the ring 23 to form an integral piece or support. The spokes also, adjacent the ring 23 may project up parallel to the ilange 26 for at least a short distance as indicated at 2t to engage the inside of the bobbins and center the support on the bobbins, thus forming a type of semi-trough for the ends of the bobbins.

Except for the supports at the two ends of the column, the intermediate adjacent pairs of supports, wherein the backs of two rings 23 are touching each other, may be `and preferably are welded or soldered together at E5 to form a unit or integral pair as shown in Fig. 3.

In Fig. 5 is shown a modified form of bobbin support 36, in a unit pair, each support Eil comprising the saine parte as in the support 2li, namely, an annular ring 33, a iiange 34, an axially spaced collar 22, and nat spokes 3l joining the collar with the ring 33, but the spokes are shown having a stepped conguration as distinguished from the angular or diagonally extending spokes 2i for the supports 20. In addition there is shown in Fig. 5 a second annular ring 35 having the same inside diameter as the ring 33 but having a greater outside diameter, at the outer periphery of which is also provided an axially extending iiange 3G, parallel to ilange 34 and forming an annular trough El with flange 34 into which trough the whole end of a cake of parallelly wound yarn may be inserted, while its bobbin nts inside the inner flange 34 as described for support 2i). In order to form an integral unit the adjacent second annular rings 35 may be welded or soldered to the ring 33 :as shown, and in order to form a unit pair, two adjacent rings may have the bottoms of their troughs 3l also welded or soldered together to prevent any iiuid from passing between them when they are mounted in a column for treating.

The construction of the supports of this invention are simple and cheap in that they may be punched out of sheet material and bent into shape and welded together quickly and in large quantities. The nat spokes thus have a certain degree oi resiliency which permits flexing without damage in the event the compression is continued between two adjacent pairs which have their collars in .Contact .as shown in Fig, 2. The

fabrication of these supports from non-oxidizable or non-corrosive sheet metal, increases their life when used in solutions which corrode other materials. The comparatively large quadrants or sectors of space between the spokes materially increase the freedom of passage of iiuid between the supports, which space did not exist when the supports were made of plastic having suiiiciently thick walls to withstand the use to which they must be put as seen in my copending U. S. application, Serial Number 661,148, iiled April l0, 1946 and now abandoned. Also, if desired, the stepped type of spokes shown in Fig. 5, may be substituted for the diagonally extending spokes 2l shown for the bobbin support in Fig. 3, and vice versa, without departing from the scope of this invention.

While there is described above the principles of this invention in connection with specific apparatus, it is to be clearly understood that this description is made only by way of example and not as a limitation to the scope of this invention.
