Application April 15, 1950, serial Ne. 156,056

7 Claims. .(Cl. 6s 19s This invention has general reference to means or supports for holding a series of annular yarn or thread packages or cakes in co-axial relation during dyeing, or otherwise treating such packages or cakes. More particularly our present improvements relate to the species or type of holder disclosed in U. S. Patent 2,625,810 granted to us under date of January 20, 1953.

The primary object of our instant invention is to provide an improved form of hollow or tubular stem and holder members or separators for annular packages or cakes including a novel type of interlocking means which positively effects retention of the package or cake separators in service position.

Another object of our present invention is to provide a support, of the species above indicated, including an approximately U-shaped interlocking element having capacity for expansion, during movement of the individual separators into service location, and automatic contractability for interlock with opposed circumferential grooves or slots provided in the hollow stem at the desired intervals or locations.

A further object is to provide a support for yarn or thread packages or cakes, in annular formation, and serially arranged in position for dyeing, as well as other desirable treatment; such support being simple in construction, strong and durable in character, comparatively cheap to manufacture, and which may be assembled and installed with a minimum expenditure of time and labor.

Subsidiary objects with ancilliary advantages, of our invention, will be or become readily apparent from the following detailed disclosure of a convenient embodiment thereof when ,considered in conjunction with the accompanying two sheets of illustrative drawings; while the subjoined claims more particularly define the features of novelty over the prior art.

In the drawings:

Fig. l is a mainly elevational view of our improved support and holder for yarn or thread annular packages or cakes, showing the device in process of loading, with an intermediate portion broken out or in section.

Fig. 2 is a top plan view of the device taken .approximately as indicated by the zig-zag arrows lIII flanking Fig. 1 and indicating one of the package separators as initially applied to the support, or prior to being turned to interlock with said support.

Fig. 3 is a vertical section and part elevational view, taken as regionally indicated .by the arrows a-a in the lower portion of Fig. 4.

Fig. 4 is a central vertical section of the fully loaded cake support or holder.

Fig. ,5 is a plan view taken on line V-V in Fig. 4, with the separators in active position; and,

Fig. 6 is a plan section taken as indicated by the angled arrows VIVI in Fig. 4.

In describing the form of our invention shown by'theaccompanying two sheets of drawings, like characters of reference are applied to correspending parts in all'the views while specific designating terms are employed for the sake of clarity, but .it is to be understood the scope of said invention is not thereby limited; each such term being intended to embrace all equivalents which perform the same function for an analogous purpose.

Referring more in detail to the drawings the improved package or cake support, as adapted for dyeing apparatus, conveniently comprises a footpiece .or socket connector I for mounting on, or integration to ,a dye vat 8,-or elsewhere as desirable; The connector '1 includes a screw-threaded bore '9 into which the correspondingly-threaded stub'part ll! of the package or cake supporting base flange .disk H is secured. Mounted axially central of the base flange disk H, as by an annu'lar Weld l2, ig. 4, is a vertically directed hollowstem 13 having the upper end closed-in at 14 and including an axial stud-projection [5. The hollow stem if is provided with groups of ,circuniferentiallyearranged perforations It, as well as spaced circumferential rings ll of holes l8, Fig. 1, said rings ll including diametrically op- Posed interruptions or blanks 19, the purpose w eres: will, hereinafter, be fully set forth. In addition to the foregoing the hollow stem [3 also includes diametrically opposed grooves or slots 20 conveniently, although not necessarily, tangentially related to the wall of said stem, as readily understood from Figs. 1, 3 and v6, more pantieularly. 7

Turning now to the package or cake holders or separators, it is to be noted that they structurally differ from those described in our prior patent hereinbefore referred to; whereas the upper

andlowerretainin holder components

22, 23,;respetive1y, generally correspond with those disclosed in said prior patent. More specifically each separator 2 c mprises two .coaxially opposed elements 24,. 24' struck from sheet mate:

rial, each embodying a fiat annular portion 25 for mutual abutment, an outer surrounding flan e and inner truncated hub portion 2 re n l unded int said ul r p rti n;

' whereas said

elements

24, 24 are preferably,

although not necessarily, united by concentric welding together of the flat sections 25 aforesaid, as conventionally indicated by the annular stippling 28 in Fig. 6. Each

element

24, 24 also has, in its hub portion, a ring of holes 29 located for spaced radial, and co-planarly related, registration with one of the rings ll of perforations l8 in the hollow stem l3. Attention is now dirooted to the fact that the lowermost unitary element 23, see Fig. 4 to best advantage, is permanently secured to the upper face of the circular base flange II, by inner and outer seam welds 3|], 3|; whereas the uppermost unitary element 22 is secured by welds 30, 3| to the under side of a retaining clamp-plate 32 having a central orifice 33 for passage downwardly over the axial stud l at the top of stem l3 and rigid attachment, by aid of a wing-nut 34 for instance, in an obvious manner.

Attention is now directed to the interlocking means effective to positively retain the package or cake separators 2|, axially aligned in compact sequence; said means conveniently consisting of an approximately U-shaped grip element or clip, comprehensively designated 35. Each clip 35, as best shown in Fig. 6, is conveniently formed of suitable gage spring wire to embody a medially-related obtuse bridging-portion 33 including a central elbow-bend at 31, opposed reverse bends 38 merging into the leg portions 39 of said element 35, while the leg portions 39 have their free ends angularly inturned at 40, to facilitate their initial expansion during application to the holder spindle I3. The clip 35 is, preferably, rigidly integrated by a weld 4| at its elbow bend 31 to the merging region of the holder opposing truncated flares 21, so as to normally occupy the internal annular recess in the plane of abutment of the meeting

annular sections

24, 24 of the aligned separators 2|, as clearly understandable from Figs. 1, 3, 4 and 6. In other words, the clips 35 are planarly secured to the outer sections of the respective hubs 21 so that the leg portions 39 thereof will automatically snap into the opposed grooves or slots for interlock with the hollow stem l3, see Fig. 6. Incidentally it i emphasized, at this juncture, that pairs of grooves or slots 20 are required and diametrically located or arranged in 180 relation, while the spacing thereof is in accordance with the size of the packages or cakes 45 to be treated; whereas the normal distance between the leg portions 39, of the respective clips 35, is less than the outside diameter of the stem l3. It is also to be observed that as each separator 2| is pushed down over the closed-in end [4 of the spindle I3, which is beveled or rounded at 42 to facilitate such action, the leg portions 39 of the associated spring clip are slightly expanded for slidable passage along the outer surface portions of said stem 3. Furthermore, in order to expedite and control application of the separators 2| into correct locking position on the stem I3, as well as their removal therefrom we provide the upper outer face of the closed end M with diametric and reversely pointing arrows 43, directed to the vertical lines of slots 20, for registration with initially opposingly-directed arrows 44, pointed at right angles to the clip 35, on the upper and/or lower outer faces of the respective separators 2|. In loading the device a cake is inserted around the stem I3 and lowered to proper location on the bottom element 26. A separator 2| is next started as shown in Fig. 2 with the

arrows

43, 44 at an angle 90 degrees which places the clip 35 at right angles to the series of slots 20. The separator 2| is then pushed down the stem I3 to the vicinity of the cake 45 as shown in Fig. 1. Thereupon the separator 2| is turned 90 degrees from the position indicated in Fig. 2 which brings the clip 35 into the smooth or blank areas I9 or in line with opposed slots 20 and the

arrows

43, 44 alignedly register as shown in Fig. 5; whereupon a slight downward push automatically effects engagement of the leg portions 39 in the desired slots 20 for interlocking and so holding the cake in its proper place. The upper holder 22 can be directly registered as in Fig. 5 and pushed downward for engagement with the uppermost slot 20, thus expediting the loading. In other words, the

arrows

43, 44 serve to position the several separators 2| so that the leg portions 39 of the clip 35 ride easily along the smooth surface portions of the stem l3; whereupon by impartation of a quarter turn, to either hand, and an additional slight down push, said leg portions 39 will automatically snap into the relatively confronting grooves or slots 20, with resultant retention of the respective separators 2| in service position. The operation just explained is successively repeated until the stem I3 is fully loaded with the cakes and separators 2| whereupon the upper holder unit 22 is applied and clamped down by the wing-nut 34, in a clearly apparent manner, when the combined stem 3, holders 2|-23, and packages or cakes 45 are ready for dyeing, or other desirable, treatment.

To remove the successive packages or cakes 45, the wing-nut 34 is removed and the upper holder semi-component 22 lifted off; whereupon the upper package or cake 45 is released and separated from interlocking engagement with the associated spindle grooves or slots 20 when each intermediate package or cake separator is successively given a quarter turn to place the

arrows

43, 44 in right angular relation, see Fig. 2, and thereupon withdrawn from off said stem I3, in an obvious manner. The lowermost package or cake 45 is simply drawn-off the stem l3, owing to the supporting holder or unit 24 being rigid with the base as hereinbefore explained.

From the foregoing it is felt the merits and advantages of the instant multiple package or cake holder means will be fully appreciated, while its serviceability and utility are equally apparent, and that the use thereof is in no way restricted to the dyeing of yarn or thread; accordingly, the right is reserved to make structural changes or other embodiments such as the particular usage of our invention may require.

Having thus described our invention, we claim:

1. In a support for a pile of annular yarn pack- ,ckages having pairs of tangential di. .netral notc' es spaced by a distance corresponding approx...-ate1y to the thickness of the yarn packages. and provided at one end with a stop element for the first applied yarn package; axialiy-apertured separators adapted to be impaled upon the stem respectively over the successively applied yarn packages, each separator having connected thereto a stem embracing spring clip capable of yielding laterally incident to impalement of the separator upon the stem, and to snap into a pair of the notches in the stem upon partial rotation of the separator after it is slid into contact with a previously placed yarn package.
