Application-Anti), leii'asemin-Nb;iii-1150 1 e claims. (or; es-'19s") My invention relates to apparatu for dyeing yarn in. package form, particularly to spindles for supporting packages duringthe dyeing process; and for its primary object to provide an improved spindle which is capable of increasing the volume of dye liquor therethrough andv thus enable more uni-ts to be dyedper spindle.

Ithas been the practice heretofore, as far as applicant is-awa1'e,-to provide a perforatedv hollow spindle having. an open. socket atone end for attachment-to a perforatedcylinder of a dye carrier and at. the other end a cap for sealing the liquor, so that flow thereofis-directed longitudlnally along the open socket and spindle,

thence transversely throughthe perforationsof the spindle and tube on which the cap is wound, andfinally through the wound yarn; It has been known also to provide a fin type spindle, cross shaped in transverse section as indicated in Drum et al. Patent 2,306,719 of December 29, 1942; for supporting packages during the dyeing process. However, in these conventional spindles the volume of liquor, flow therethrough is restricted to the internal open area of the spindles.

ln-the hollow perforatedspindle-the total available areais limited by the internal. diameter therefoi' and, since the perforated tubes'carry-ing the packages;- are superposed thereupon, the thickness-oi the perioratedspindle is the limiting factor; In-the fin type spindle the thicknessoi the material comprising the cross shaped'fins limits-v the areaavailable for liquor, flow.

Accordingly;.-it-is another object ofmy invention.,=to- -overcome the abovedisadvantages by providing-i a-greater area for liquor flow in thesupporting spindleand alsoat the socket end of the spindle;

Wit-h theabove objects. inview; an; embodiment of my: invention discloses aspindle; assembly comincreasing, thevolume-gidiquonthat mayi-be-introduced into'the spindle.

1 2" According. toa feat re of iiiyf invention advantages are secured over the prior spindles by pmvidin'g in my spindle assembly a separablesockfet and rod, so that upon ineffectiveness of therod it is'rnerely necessary to replace the rod and not the socket as well, thus resulting in substantial savings. v v

For a more complete" understandingoi the nat'ureand s'cop'e of my invention, reference may be had to the following detailed description ta'ken in conjunction with the accompanying drawing in which: n v

Fig. 1 is a sectional elevational view of my improved: spindle for dyeing yarn; in" package form; q.

Fig. 2' is a sectional View of the sametakein along line 2-2 of Fi 1- in the direction of the arrows; and- Fig. 3 is-another' sectional viewtaken. along line 33 of Fig. 1 in-the-direction of the arrows Referring now to the drawing; particularly to Fig. -1, there is shown a'spin'dle assembly ID comprising an elongatedrsrod: H and asocke't l2 111emovably attached: to a dye carrier plate It, which latter is of conventional configuration and well known in the dye art.

The outer peripheral surface l4-of. the socket i2 is threaded'for' mesh engagement with .a threaded opening l6 in the carrier plate [3 "and .I prefer tormake this peripheral surfaceslightly tapered, asshown, so that the end portion: l1 thereof may be readily passed through and thus extend beyondthe plate :3 for apurpose that will appear hereinafter. The socket-end. portion H is shown provided" with a threaded, longitudinal'bore I 8 for mesh engagement with theithreaded" end" 19 of the rod H; which also includes a shoulder 21 'for limiting the depth to which the rodmaybe inserted'sinto the socket. It isto be noted, therefore, that the end portion of the sccket acts as a closure when the rodis assembled thereto. Inwardlyof this closure is formed" a longitudinafbore 212; the diameter of which is at least equal tothe" inner diameter of a; conp des a ou d. he fii ihe j .si rie .42. and "extend" ldngitudinany a" predetfniinedhistanc.

The total entrance cross-sectional area, as represented by the sum of the individual openings 26, is arranged to be greater than the cross sectional area of the bore 22 or tube 23 minus the cross sectional area of the rod 1 l in order to provide, a mentioned hereinbefore, for increased liquor flow therethrough.

This increased liquor flow will be readily ap parent from the following mathematical comparison between a conventional spindle assembly having a perforated tubular spindle and the spindle of my invention. A conventional perforated rayon cake tube, such as tube 23 in the drawing, has an inner diameter of In my spindle the spindle rod H is A" in diameter, which is sufficiently strong to support the required number of wound packages 24. In the prior art perforated spindle tube the inner diameter thereof is and it is to b noted that in conventional practice the inner end of this tube is open and the dye liquor enters through this opening and, since the other opening is closed, the liquor is forced through the perforated openings in both tubes and thence through th wound package, as is well known.

The areas of the various parts are as follows:

1. 0.40574 sq. in. for perforated tube 23 2. 0.04909 sq. in. for A" spindle rod H 3. 0.19635 sq. in. for perforated spindle of prior art The difference,

0.405740.04909=0.35665 sq. in.

represents the net cross-sectional area available for liquid flow in my arrangement; and, since the total cross-sectional area for liquor how in the prior art spindle is 0.19635 sq. in., the difference, 0.356650.19635=0.16030 sq. in;, represents the greater amount of cross-sectional area available for liquor flow, which area is almost double that heretofore possible.

In view of the increased volume of liquor fiow available through the socket of my invention it is thus possible to install more than the conventional three packages and still maintain a satisfactory flow condition.

At the other or front end of the socket I2 is shown an enlargement 2? having a plurality of angularly disposed, side faces 28 in the form of a hexagon for facilitating, by use of a suitable tool, attachment of the socket to the carrier plate. The enlargement 21' is also provided at its front face 29 with a recess St, the wall of which is arcuat in outline and which begins at the front face 29 and continues rearwardly and inwardly, as shown, to the bore 22. The recess 3! is thus particularly adapted to seat the perforated tube 23 coaxially with respect to the spindle rod II, as shown in Fig. 3, whether the spindle is mounted vertically or horizontally.

The assembly of the spindle to the carrier plate (3 is a simple and straightforward operation requiring merely the rotational movement of the socket 12 until it is firmly secured in the threaded opening l6, as shown in Fig. 1, after which the elongated rod H is inserted into the threaded opening !8 of the socket it. Once the spindle is in position the perforated tubes 23 carrying the packages 24 are mounted thereon with the innermost tube 23 centrally disposed in the recess 3|.

To assure a coaxial arrangement of all superposed tubes I provide a spacer 32, having a recess 33, similar to recess 3|, on opposing faces thereof, between each pair of tubes 23 and also a similar self-centering recess on a threaded cap 4 34 for sealing, and a nut 36 securing the entire assembly together on the spindle rod ll.

From the foregoing description, it will be seen that my invention provides a simple, practical spindle which is formed of parts that can be economically manufactured, easily handled, and can be conveniently used. Further, with my invention it is now possible to substantially increase the flow of dye liquor and thereby process more packages in the same period. Also, repair of a bent spindle is readily eifectecl by mere replacement of the spindle rod l I.

As various changes may be made in the form, construction and arrangement of the parts herein, without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matters are to be interpreted as illustrative and not in any limiting sense.
