To all whom it may concern: Be it known that I, RALPH IMrRorA, a

citizen 'of the United States, residing at Paterson, in the .county of Passaic and State of Newf Jersey, have invented certain new and useful Improvements in Wound Packages and Methods of Making-Same; and I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in' the art to which it' appertains to make and usethe same- My invention relates to wound shuttle packages having a-quill or other core for the windings, and has reference more partic-' ularly to packages in which the windings are of tinsel, knownas lame, or of other smooth, fiat, hard filament having no fibres capableof intermingling with each other.

and no elasticity to prevent the convolutions from-slipping uponeach other. Metallic wrappings of this naturehave a: great deal more weight than silk, cotton or wool threads and consequently'p ossess more inertia, which characteristic, combined with those above defined, has resulted in severeloosening of the wrappings upon .the ordibeen the practice to wind the strand-back nary core or-quill incidentflto the stopping and starting of the shuttlein the loom, causmg tangling and snarling of the filament and making it practically unusable. siderablesuccjess with tinsel .or lame has been obtained by winding only arelatively thin shellv of the filament upon an. en-

larged core, but this. type of package per:

mits the carrying of. only a very smallamount of the material on the core and consequently requiresa great deal of time in placing new packages vented from slipping down on each other.

'1 This method-results inthe ends of the layers of windings adjacent the small or outer removing'cores and the shuttles. I

"The cores to'whichll-have referred are tapered or enlarged toward one end and the disadvantage a ove pointed out. It is filament is Wound back and forth thereon into superposed layers whichare advanced successivelyirom the large-end of the core or quill, but the ackages so wound have the therefore the rincipal object ofmy ll'lVGIl'.

,tionto 'p'rovi e' a new method of winding lame or similar filament in such a manner that a maximum amountgof' filament of the character mentioned may be placed. upon the core but will have no tendency-to loosen :thereonor snarhpermitting it to "be han- Con- ' died by a shuttle as expeditiously as brdi:

' the layersto slip upon'each other'and tangle, so that it is a further aim of my invention to unwind in a diilerent manner, overcom m 'this dlficulty.

so; A

' llVith the foregoing in view, the invention "resides in the novel subject matter herein.-

after described and claimed, the description being supplemented by the accompanying draw ngs. 7

Figure 1 is a diagrammatic view exaggerated to show the-- relation of the numerous layers of windings.

' Figure '2 is a diagrammatic elevat'onshowing' thejmanner of winding the first layerr" Fig'urefi is'aiside elevation of a complete v package formed in accordance with my in 'ventlon. a

While in winding quills in the past, a has andforthfo'rming a plurality of superposedor core, workingbackward toward its base so that the ends of the layers "of winding adjacent'th'e base will be supported by the cone or tapered portion ofthe quill and be pre end of the quill being-securely-held in posia tion by the succeedingfsuperimposed layers and in actual practice I have-found that there is no tendency whatever'of the filament knocking loose and snarling'du'rin the 1 operation of the shuttle inthe loom. Vi 'le the core or quill. 1. may be gradually tapered throughout its length, I prefer to .make' it as shown in the drawingswith asmall end and a distinct enlarged or cone-she dend or portion 2, which is 'substantia y one-1 -halt. the length of-the quill. lhave found in practice that it is important to havethe taper or cone portion with a slow taper,-tha t 1s tr emely acute angle-to as clearly shown smaller portion the axis of the quill in Fig. 2. If desired, the ofthe quill may be tapered somewhat toward the cone to permit the first few layers of windings to effectively cling to it but it may be made straight and provided with grooves 1* for the same purpose. Both the taper and the grooves may however be used and both are illustrated in the drawings.

In winding thequill, it is placed in a suitable traverse winding machine and the strand-or filament 3 is wound back and forth upon it, fiat side contacting, into a plurality of superposed layers, while the successive layers are advanced longitudinally along the quill from the smaller end thereof. The first few layers of windings may be disposed entirely upon the smaller portion of the quill, terminating in slightly spaced relation from the enlargement 2, as indicated in Fig. 1, but the remainder engage or terminate upon this enlargement and are backed up thereby, so that said layers cannot bodily shift and permit the mass of windings to break down adjacent the enlarged end of the core. lnother words, after one or more layers have been laid upon the smaller, portion of the core, the remaining. layers and around the inner ends of the preceding layers into engagement with the enlargement 2. As above indicated, this method of winding prevents any shifting of the convolutions at the other end of the core and although the package may be wound to maximum size, the forcible strokingand sudden stopping of a shuttle in which it is used will not affect its integrity in any manner whatsoever.

The winding operation above defined,

produces a tapered formationto the 1111':

merous layers throughout portions of their lengths, as indicated at 5 and by placing the package in the shuttle in such a manner that the strand 3' will unwind by pulling" toward the larger ends of these tapered portions ofthe layers, as indicated in Fig. 1, there is no tendency .for said layers to slide one upon the other. However it is not essential that the strand be pulled in this manner, as the package is so rigidly constructed that, the strand may also be unwound by pulling in the other direction,

without producing any serious results. This manner of unwinding has been indicated in Fig. 3.

It will be seen from the foregoing that V I have greatly improved both the method of winding lame or other smooth hard fiat filament and the construction of shuttle packages formed by carrying out the Windwith the surface of the cone at an exare carried beyond.

ing operation upon a'core, and while the distinct improvements which I have made, will be clear from the foregoing, it may be well to summarize them as follows :--I take a core having a taper or a tapered enlargement at one end and wind the flat filament;

flat side contacting, back and forth thereon, into a plurality of superposed layers, while advancing the successive layers from the smaller end of the core and carrying them into engagementwith or building them up backwards and upon the cone or tapered portion. By so doing, I produce a shuttle package which will be entirely free of objections heretofore'encountered when using any smooth, hard, fiat strand which is liable to slip and snarl. I unwind the strand, preferably by pulling it toward the end of the core upon which the winding operation was started, which overcomes any liability of the conical portions 5 slipping upon each other, but as above stated, it .is not essentialto pull in this direction. Specifically of a maximum amount of lame or other smooth flat filament upon a core and have ,speaking, I have provided for the carrying provided for successful, unimpaired use of and forth upon the core to form a plurality of superposed layers, while advancing the successive layers along the core from the smaller end toward the abutment thereof and carrying the inner ends of the layers 'into engagement with the abutment.

2. The method of winding lame or other smooth, fiat filament upon a core having a cone-shaped portion and a smaller portion, consisting in traverse-winding a few layers of filament on the smaller portion terminating such layers short of the cone, then 7 continuing the winding and working toward and up upon the cone to produce a body of winding having its outer surface tapered at both ends. V o

The method of winding lame or other smooth, fiat filament upon a core having a portion tapered from one end, consisting in winding back and forth upon the core to form a plu rality of superposed layers, while advancthe successive layers along the core from the smaller .end thereof, and carrying the filament, flat 'side contacting,

' raeedaa them beyond and inwardly around the inner ends of the preceding layers, thus building them up upon the tapered portion core.
