'z emma (ci. 24a-12o) 'I'his invention relates to improvements in textile spools.

It is an object of the invention to provide a textile spool or winding. tube suited for receiving textile ilbres from spinning machines and which is of low weight and cost, permitting it to be used for shipping packages, where desired. Many features of the invention are applicable also to driven textile spools and to cops, tubes,

y pear in the following description in mind, the

invention consists in the combinations and arrangements of parts and details of construction which will now ilrst be fully described in connection with the accompanying drawing and then pointed out more particularly in the appended claims.

In the drawing: Fig. 1 is an exploded view in central longitudinal section showing the parts going to make up a angeless pim or winding tube embodying the invention in a preferred form; A

Fig. 2 is a side view, partly in central longitudinal section, showing the completed structure made up of the partsvin Fig. 1;

Fig. 3 is an end view showing the drive end of the pirn Fig. 4 is an end view showing the opposite or winding end of the pirn;

Figs. 5 and 6 are transverse sections taken respectively on the lines 5 and 6 of Fig. 1; and

Fig. is a fragmentary side view, partly in central longitudinal section, showing a modified type of construction for the winding end.

'I'he barrel of the pirn includes an outer tubular barrel l, preferably of pasteboard or similarly deformable material and which may be impregnated witha phenolic resin or the like so as to harden it and improve its surface characteristics. Within outeribarrel l are positioned outer and inner split metal tubes 2 and 3 respectively, the splits in which are preferably positioned opposite each other where very accurate balance is required. 'I'hese split metal tubes are urged outwardly against the inner surface of outer barrel l by transverse annular 'or cup-shaped braces 4 which are driven into tube 3 so as to force the tubes 2 and l 'outwardly against the company, Inc.,

outer barrel l with sufcient pressure to compel the outer barrel l to conform to the straight cylindrical contour of outerl tube 2.'

' The drive end assembly includes a metallic cap member 5 which may be drawn from a, single piece of metal and which has a central aperture li forming a spindle bearing. 'I'he cap member 5 includes also a cylindrical portion 1 concentric with the aperture 6 and adapted to be driven into tube 3. A plug Bof wood or any .other desired material provides means for engaging the whorl of a spinning machine, being formed with a central opening 9 to accommodate the spindle and a transverse slot I0 to engage the lugs of the whorl. The central opening 9 should be larger in diameter than the spindle and the spindle bearing 8 so as not to interfere with proper engagement and centering of the spindle by the spindle bearing E. The plug 8, where made of wood, may be provided with any of the usual metallic facings or protectors at points of wear. Plug 8 is formed with a cylindrical portion Il which fits into cylindrical portion 'l of the cap member and is fastened therein as by means of inwardly punched portions I2 of the cap member metal. Below this cylindrical portion the plug is provided with an annular shoulder I3 which engages against a corresponding at portion I4 of the cap member 5. Cap member 5 is provided with a skirt or rim l5 adapted to fit over the end of the barrel as shown in Fig. 2 and to be pressed into the barrel so as to fasten the drive end assembly thereto.

The end assembly comprises an upper spindle bearing I6 which includesV an aperture l1 to engage a spindle and a body portion I8 concentric therewith and adapted to be driven into tube 3 as shown. It will be noted that this upper bearing construction permits the use of winding tubes or flangeiess pirns upon spindles designed for shorter pirns. One connection in which this feature assumes importance is in the use of a flange'less pirn as a substitute for a single anged pirn. In such use the bre will be wound upon the barrel in the form of a cylinder with sloping or truste-conical ends and over a length such that the ber doesnot touch the skirt I5 at the drive Aend or reach the end of the barrel at the winding end. Under such circumstances, it is necessary to provide a longer structure if the same amount oi material is to be carried as can Vbe woimd upon a flanged pirn.

.A bearing surface for the textile ibre is provided in the form of a washer I9 surrounding Il outer split metal tube 3 and abutting against a smooth surface for the thread to pass over and canbe'grounddownornolishedasrequlredto eliminate nicks or other irrcgulariti. Washer Il is provided with an annular recess 2l receivinganangleshapedringbymeansofwhich thewasherisnelduponthebarreitheendzz of outer split metal tube 2 being turned over, as shown, for that purpose. The upper end assembly is completed by a cap member 22 providedwithanaperture Ntoaccommodatea spindle, but which should be of greater diameter than aperture I1 so asnot to engage the spindle, and with a cylindrical portion 2l adapted to be driven into inner split metal tube 3. The rim 21 of this cap member is turned over the end 22 oftube2soastocoverthesameandtofasten cap member 23 to the pirnr` 'I'his cap member furnishes a place for the insertion of identifying cards and may be provided with inwardly extending nibs 2l for holding the same. The cap member may abut against member it as shown in Fig.2forthepurposeofholdingthebearing I1 in place against any upward thrust of a spindle during placing of the pirn thereon.

The structure of'the invention may be assembled as follows: the inner and outer split metal tubes 2 and 3 are placed within outer barrel l and the expanders 4 driven in as shown in Fig. 1. Washer II and ring 2| are now placed in position and the upper end 22 turned over as described. Insertion of upper bearing member Il completes the assembly so far as shown in Fig. 1. 'Ihe insertion of cap member 23 and the turning over of its rim 21 completes the assembly of the winding end and the insertion of the drive end assembly and turning inward of skirt I5 completes the assembly of the drive end.

As will be apparent, the construction of the invention involves the use only of simple and easily constructed parts which may be assembled without diiliculty or the employment of precision methods. Nevertheless, dynamic balance and concentricity are insured by the centering of the bearing and driving members with relation to the inside of the inner tube, as described. 'I'hese features, together with the great barrel strength provided, are of particular importance with synthetic fibres such as rayon, Nylon" or the like, and insure satisfactory operation in winding at speeds of about 8000 R. P. M. l

In certain casos where washer Il is not required, a modified upper end construction as shown in Fig. 7 may be employed. In this case both split metal tubes terminate with outer barrel l or slightly short of the end thereof and a cap member 29 is inserted therein. The rim 30 of this cap member is turned into the end of outer barrel I as shown in Fig. 7. The cap member 29 being otherwise similar to cap member 23 previously described requires no further description. I

It will be apparent that many features of the present invention and principally those relating to the barrel reinforcement are applicable to single or double flanged constructions, as well as to the uniianged construction shown.
