CHARLES P. MITCHELL, 0F ARLINGTON HEIGHTS, MASSACHUSETTS.

THREAD-PACKAGE.

Application filed June 7,

Toall whom.- it may concern:

Be it known that I, Cannons P. Mireil- ELL, a citizen of the United States of Americe, and a resident of Arlington Heights, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Thread-Packages,

of which the following is a specification.

This invention relates to packages of continuous thread, cord, or other similar materials, and particularly to those packages which are wound to a. large diameter as com pared with the diameter of the tube or core on which they are supported and in which 1 the number of winds or eonvolutions in the several wrappings decreases as the body of thread or other material increases on the tube or core.

The object of the present invention is to produce a package which will contain a greater quantity of material than is generally contained in a package that will occupy the same cubic space wound in this manner under the usual methods.

The invention consists in making a pack age of a plurality of sections of which each one starts with a wrapping or helix of a certain number of winds, the number of winds gradually decreasing with the increasing size of the section; a new section being started at a convenient period with a wra ping which has a greater number of win s than those completing the previous section, the progress of the winding in each section being accompanied in each section with a decrease in the number of winds per wrapping.

The invention consists further in certain. novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents, in diagram, a tube or core having wound thereon the initial wrapping of the first or inner section of a package with a given number of winds, as, for instance, four (4). Fig. 2 represents, in diagram, the same package at the completion of the first section, the exterior wrapping of which has a lesser number of winds than the initial wrapping, as, for instance, two (2). Fig. 3 represents, in diagram, the same; package with the initial wrapping of the second section wound thereon, the number of winds Specification of Letters Patent.

Patcnted July 28. 191d.

1909. Serial No. 500,970.

therein being greater than that of the elite rior wrapping of the first section upon Q which it is wound, as, for instance, three (3). Fig. 4 represents, in diagram, the complete package, the exterior wrapping of the second section having a lesser number of winds therein than the initial wrapping of said section, as, for instance, one and onehalf (1 1;). Fig. 5 represents an end view of the same, and Fig. (3 represents an elevation of a package formed without changing the length of traverse of the thread guide during the winding.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 represents a tube or core upon which is wound a first section 11, which in turn has superimposed thereon a second section 12. Each of the sections 11 and 12 is composed of a plurality of wrappings of thread, cord, or similar material, the number of winds or convolutions in the initial wrapping of each section being greater than the number of winds in the ex terior wrapping thereof. F or instance. as indicated at 14 in Fig. 1, the initial wrapping 13 has in the length of said package four winds. As the first section is built up the succeeding wrappings have. fewer winds than the next preceding wrapping received. The length traversed by the thread guide is made shorter as said package increases in size, thereby forming the tapered end 15. As a consequence of this gradual decrease in the number of winds in the successive wrappings from the initial wrapping outward, when the first section of a. package having four (i) winds in the initial wrapping thereof has been built up including the tapered ends. it. will have in its exterior wrappings 13 say two (2) winds, as indicated at 16 in Fig. and will contain approximately the same quantitv of material as similar packages wound in this manner under usual methods. It is evident that while such manner of winding continues, the winds of the successive wrappings will become more and more separated with increasing space not occupied by the material.

To improve this condition and produce a package in which more material can be containcd in a package of similar size wound in this manner is the object of the present invention. This is accoi'uplished by building up the first section as described, and changing the traverse mechanism to locate in position and increase the length of the material in the initial wrap ing 17; Fig. 3 of the second section whic will contain a number, of winds, say, three (3), indicated at 1'8, Fig. 3 greater in number than that P of the exterior wrapping of the first section which was two (2). The second section is built up in the same manner as the first section, the successive wrappings having fewer winds as the winding progresses until the ackage is completed, as shown in Fig. 4, w on the exterior wrapping 17* of the second section 12 .will contain a lesser number of winds than the initial wrapping 17 thereof, as, for instance, one and one-half (1%), as indicated at 19, Fig. 4; and since the wrappings now contain more material and are more closely wound than in the outward wrap ings of the first section, it is evident that file second section thus wound Wlll containmore material in the same cubic space and hence-a greater rl uantity of material in the whole package. 11 a package wound in this manner, the sections may be so proportioned as to contain a larger or a smaller quantity of material, as may be desired, to change-the capacit of the package; and there will be less di erence in the density of the bodies of material in the inner and outer sectionsthan heretofore in packages wound under the usual method. Where material, such, for instance, as a sliver of wool, is wound into'a package in this manner without changing the len h of traverse of the guide during the win ing of the whole package, said pack 0 will have ends similar to those shown in ig. 6, and it may be wound on a tapering or a collapsible mandrel which can be removed when the winding is completed. Each successive section is, in efl'ect, a body of the' material complete in itself woundu n a larger core with more material in e initial wrapping and otherwise differentiated from the next preceding section; and as no attemptis madetocontrol the placing of the material, or the spacin of the winds, defects arising from sun 11 threads, threads that overrun the ends of the package, and the like, that heretofore sometimes continue to the end of the winding, will generall be confined to the section in which said de ects occur. SlIlCB the surface upon which the initial 'wra -ping of the second section is wound difiers rom that of the tube or core upon which the initial wrapping of the first section is wound, and will vary in different packages from defects in the winding that cause irregular formation of the packages, it must be understood that the number of winds in'the initial and exterior wrappings of a section approximates the numbers specified herein. For purposes ofdescriptmn in each section the interior wrapping having themost winds,

therein is to be considered the initial wrapping thereof, and, likewise, the outer wrapping having the least winds is to be con- .sidered the exterior wrapping thereof.

The term wrapping as used herein refers to the quantity of material wound around the package while it is advancing in one direction or the other between one point of reversal and the next point of reversal without regard to the number of winds therein or to the location of said oints of reverse anywhere between the en s of the package. For some purposes it is necessary that the tapered ends of the package should be of well-defined proportions in order that the material may be readily unwound therefrom. It has been found in practice that a more desirable form or outllne of tapered ends can be produced in packages wound as herein described and that the waste caused by imperfectly formed ends is materially lessened in consequence.

The diagrams illustrated in Figs. 1 to 4 inclusive are shown greatly exaggerated with the .ends of the outer section some distance from the endsof the inner section, but it is quite evident that there will be no such distance'between the two ends of the sections in practice, for it is obvious that more material can be wound upon the package when the initial wrapping of anouter section is substantially of the same length on the body of the package as the outer wrapping of the section upon which it is wound.

It is evident that the invention is not limited to the recise construction and arrangement set orth, but may be variedms desired in order to meet diflerent conditions.

Having thus described my invention, I claim:
