16 claims. (o1. 11m- 52) This invention relates to a novel and improved form of thread, the novel features of which will be best understood from thefollowing description and the annexed drawing, in which we have shown a selected embodiment of the thread and have illustrated a method by which it may be made. In that drawing: i

Fig. 1 is a perspective view of a cheese formed of the various elements or ends which are to be made into the thread;

Fig. 2 is a view on a greatly enlarged scale of a portion of the structure appearing in Fig. 1;

Fig. 3 is a View of a fragment of the finished thread, with the end portion thereof opened out to show the construction or" the diierent elements or ends.

According to our invention, the thread is formed by twisting together a plurality of strands.

which condition the yarn has what may for con-v venience be termed an ordinary twist. We do not, however, desire to limit ourselves to any particular form of end, although in actual practice we have found very good results to follow from using,

as the .single ends, yarn.k of the kind just mentioned above.

In the illustrated embodiment, the finished thread is formed of six single ends, all told, and all having the same order of` twist. Two of those single ends are rst twisted together to form a double-ply end and then twisted together with the other four single ends to form the finished thread. The two single ends 1 and 2 are shown as having been twisted together to form the double end 3. Each end 1 and 2 has been previously twisted to the left and then formed into the double-ply end by a left twist. That is to say, the twist in each of the individual ends 1 and 2 is the same in direction as the twist in the double-ply. end formed from these twosingle ends, thus giving a construction which may be termed a twist on twist arrangement.

The double-ply end 3 may be Wound very conveniently with the single ends 4, 5, 6, and 'i into a cheese 8, with the double-ply end 3 having two single ends on either side thereof.

Then the five elements, consisting of the four single ends, and the one double-ply end, may be twisted into the finished thread illustrated in Fig. 3. In this twisting operation, as in the formation of the double-ply end, anyY suitable twister may be used. Preferably, this final twisting operation is performed in a direction opposite to the twist of the individualends and of the double-ply end. In this particular vinstance then, in which the single ends and the double-ply end have been twisted to the left, the twist of the finished thread is to the right. By this arrangement, a better balanced thread is obtained, giving the required strength and reducing the tendency of the thread to kink. f p

The end 3, here shown as of double-ply construction, forms a multiple-ply end twisted with single-ply ends to form the thread. It will be seen that the thread thus formed comprises single ends twisted together, with the multiple-ply end running lengthwise of the thread and following the twist thereofgiving the thread a cable appearance. While the multiple-ply end is shown as formed of two ends, thisnumber may be increased where found desirable.

We4 have found that a thread made as described above has several advantages over the prior art thread. ,One of these advantages is that much greater strength is obtained. As is well known in the, art, American cotton, since Sea Island cotton'is no longer grown commercially, has a shorter staple and coarser fiber than Egyptian cotton, for example, and therefore the Egyptian cotton normally gives a stronger thread than American cotton. The Egyptian cotton, however, requires an extra bleaching over that given to American cotton. With our invention, we are enabled to use American cotton and get a thread approximately as strong as a thread made with Egyptian cotton according to the prior art practice. Similarly, with Egyptian cotton or other relatively long staple cottons, a correspondingly stronger Ythread is obtained. Y

While wehave shown the invention embodied in a certain form, we, of course, appreciate the fact that various changes may be made without departing v'from the scope of the invention. The amount of twist per inch in each single end and in the multiple-ply end may be varied as found desirable, and likewise the number of ends may be changed, although we have found that the number shown herein gives excellent results. Therefore we do not intend to limit ourselves except by the appended claims.

We claim:
