yarns are drawn from the Patented Oct. 4, 1932 UNITED STATES PATENT OFFICE ANDREW WYLIE, OF TOTOWA BOROUGH, NEW J EBSEY, ASSIGNOB T0 HARRIS BROS. SILK COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY WOUND PACKAGE Application filed September 4, 192a. Serial in. 390,271.

The preparation of warps is now being effected with the use of a creel on WhlCh the wound packages from which the yarns are taken are arranged in upright planes converging toward the warping machine the axis of each package projecting more or less horizontally and forward, whereby the packages lengthwise of their axes instead of tangentially. So that the warpin operation need not be stopped when a pac age becomes exhausted the leading end of the yarn of one package (being what I term herein its inner end, or the end first wound on the package core and therefore the end last to be delivered in the unwinding) is connected to the other end (or what I term the outer end) of the yarn of another package, the first-named end being left free as a reserve when the package is formed. On account of the handling which the package undergoes between the time it is formed and the time it is put into use on the creel it is undesirable to have this reserve or inner end loose and of course it must not be loose when the package in being formed is rotated, so it has heretofore been tucked into the axial hole in the package core. Th1s could be done where the core was a cone or other flangeless one, but where the core was in the nature of a spool, i. e., a peripherally flanged core, so that said inner end had to extend around a flange of the core in order to be tucked into the hole, it could not be done with assurance that handling of the package and incidentally of the flange would not result in drawing said reserve or inner end out of the hole and so leaving it extending loose and Without the likelihood when the core was placed on the winding spindle of said inner end being soiled or marred or perhaps broken off by the clampingaction of said spindle in the hole.

Consequently spools have heretofore been regarded as impracticable for supplying the yarns in this t pe of warping, although they are preferred because they do not require to be wound as tightly as cones, nor with a cross- Wind, as do cones, conditions which sometimes give rise to the possibility of the warps showlng pressure marks likely to appear as blemishes or other irregular places in the cloth into which the warps are woven; and under certain conditions a creel equipped with spools will have a greater capacity than one equipped with cones.

The object of this invention is to provide a wound. package to be used in the kind of warping indicated (or for any other purpose, in fact, where the inner end of the yarn is to be left free of the main mass of windings) comprising a core of the flanged type and yarn or other flexible strand wound on the core body and having its inner end forming an ample reserve and releasably secured to the core in an independently wound state.

In the accompanying drawin Fig. 1 is a side elevation of tire improved wound package;

Fig. 2 is a section on line 2-2, Fig. 1; and

Fig. 3 is an end elevation.

1 designates the body or barrel of the core. 2 is its basal flange and 3 its outer flange, the core illustrated being in the example intended for use in warping on a creel 'of'the type already indicated. The presence of the flange 3 is not material. v

Flange 2 has a peripheral recesshere in the form of a groove. In the example said flange also has at the inner side of the groove a notch 5, preferably V-shaped as viewed from the inside of the flange; at the outer side thereof it has a notch 6, preferably offsetcircumferentially with respect to the notch 5; and more or less diametrically opposite these notches it has a notch 7, formed in both sides of the groove.

When the specific core shown and above described by way of example is employed the improved wound package is formed as follows: The extremity a of the said inner end of the yarn is first engaged in notch 7 so as to traverse the groove and protrude inwardly of the flange, whereupomwhile holding said extremity with a finger of that hand of the operator which holds the core, with the other hand said end is passed across the outer face of the flange, as at b, in a secant with respect to the perimeter of the flange, and entered into notch 6, one side of which will form a stop to prevent slippage of said end around said perimeter, whereupon it is wound more or less tightly around the flange and in the roove one or more times (incidentally crossing and thus causing said 5 extremity to be gripped between the thuswound portion and the flange as shown) and finally it is passed from the groove via notch 5 and a few turns made by hand about the barrel 1.

lVith said inner end of the yarn thus established on the core the latter is placed in the winding machine and wound with the yarn in any way, as at 0, until the main mass of windings formed on the core body and com- .prising the major portion of the yarn has as usual attained the desired size and form.

I here note that the yarn or other strand of my package has the inner end thereof forming a reserve and wound around the axis of the core independently of the main mass 0 formed by the major portion of the strand (in the example, around the flange periphery and releasably secured in its thus-woun state in contact with the flange.

The securing of said inner end in its wound state is the result of several factors, as (1) that it is tightly wound in more than one convolution and that the sides of the groove or recess 4 hold these convolutions transversely compacted and thus gripped between them, here because the sides of said recess are substantially parallel; (2) that its eX- tremity is crossed by all said convolutions and is arranged also to be crossed by the con volutions at substantially a right angle; and (3) that there is deflection in said inner end from its convoluted portion as, for example, where it extends into and here through the opening formed by notch 6.

Each of these factors may of and by itself be suflicient to hold said end secured in its wound state on the flange according to the thickness of the strand, or its degree of stiffness, or the capacity of the strand and of the surface of the flange to grip each other, as frictionally, or other qualities.

Where the winding of said inner end is actually around the flange, recessing the latter, especially if an uninterrupted groove is at least in effect formed, of course protects the windings of said end from injury and soiling.

While the said inner end or reserve is held in wound state in contact with the flange securely against displacement as an incident of mere ordinary handling or the rotation on winding the core it is removable so as to extend loose when special effort to dislodge it is applied. The removal may be effected in the example by withdrawing extremity a from notch 7 and from under the traversing convolutions and then unwinding said end.

In the example notch 5 sheathes said inner end where it extends from the groove to the inner side of the flange, thus preventing its being soiled or abraded, as might otherwise happen if it traversed the true periphery at the inner side of the groove; being V-shaped this notch permits the winding on the flange tobe either clockwise or anti-clockwise. Likewise and with the same result notch 6 sheathes the said inner end where it extends from the outer side of the flange to the groove. Notch 7 also sheathes said inner end with the same result, and it further facilitates the operation of forming the convolution or convolutions of said end around the flange, since when it is in the meanwhile clamped by the operators finger as described the extremity is held by the notch in a definite position, or against slipping around the flange.
