i claim. l

This invention relates to an-improved knot and more especially to a knot adapted to be employed in the joining together of yarn, thread, and the like used in the textile field such as the tying of parted ends in weaving, winding, reeling, and in various textile operations during the processing of the yarns and the use of the same in the manufacture of nished goods.

Heretofore when cotton and wool were largely used as the fibers from which threads, yarns, and the liker were manufactured, the ordinary weavers knot or chicken head knot would sufiice to hold the ends together when they parted in a weaving or other operation. However, in the present day, when nylon, regenerated cellulose in filament form, and other lament yarns are used, they do not oier sufficient friction to prevent knots from parting when ends are joined together by the conventional knots heretofore employed. It is therefore necessary to employ an improved knot for filamentary yarns to keep the same from parting under the tension imparted to the same in weaving, and in other operations. It is, therefore, an object of the invention to provide a knot for uniting two ends of yarn which will not slip and become parted.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:

Figure 1 is a view showing two ends of a str and in the position they occupy during the iirst stage of tying a knot;

Figure 2 is a view of two strands in the second stage of tying the knot;

Figure 3 is a view of two strands in the third stage of tying the knot;

Figure 4 is a view showing the two strands in the fourth stage of tying the knot;

Figure 5 is a view showing the two strands in the fth stage of tying the knot;

Figure 6 is a view showing the two strands in the sixth stage of tying the knot;

Figure 7 is a view similar to Figure 6 but showing the knot beginning to be tightened;

Figure 8 is a View similar to Figure 7 but showing the knot in a further stage of being tightened;

' Figure 9 is a reverse view of Figure 8;

Figure 10 is an enlarged View ofthe knot as shown in Figure 8;

Figure 11 is an enlarged view of the knot as shown in Figure 9.

Referring more specifically to the drawings, the numerals l0 and Il represent the two ends of Ia strand which may have parted and which it is desired to secure together by a suitable knot. It may represent that I0 is the exhausted end of one package of yarn and Il is the beginning end 5 of another package of yarn which are desired to be knotted together. In any event, the two ends lo and II represent usually two identical or similar strands which are adapted to be united in a knot. f

Of course, this knot is described as being tied by hand, but it can also be tied by suitable knottying mechanisms. The first step in the tying of the knot is to cross the strand I0 over the strand Il as at 9, and the second step is then to move the strand I underneath and across strand ii as at I2 to provide a right angular portion in the strand IU as it crosses the strand Il at right angles. The next step is the reversing of the strand It to form a completed'loop i3 and passing the end of the strand l0 rearwardly along side the free end of strand l i and over the strands I0 and li as at I4.

The next step, then, is to move the strand ii across and over the strand Il) as at i5. The next step, then, is to carry the end of strand ii below the free end of strand I0 and below the main portion of strand i0 as indicated at I6. The next step, then, is to bring the free end of strand ii up above the strand i0 and above its end portion as at 2@ and 2i and below the strand H as at il. With the knot thus formed, it is ready for applying opposed tension to the main portion of strands to and il to begin tightening the knot. In Figure 7, we see this partially accomplished by opposite pull applied to the main portions of the two strands Ill and Il to bring the knot into closer relation. In Figure 8, this tension has been such as to completely assemble the knot to a very tightly formed knot and, thus, the knot 40 is complete except that the tail portions I8 and I9 will be severed close to the knot so that this knot will pass through various types of textile machinery without interfering in any way with the machinery. The knot may be pulled into tighter relation than shown in Figures 8 to 11,

inclusive.

It is thus seen that a knot is provided whereby I the various portions of the knot will bind against each other and rmly grip the same and prevent slippage even of filamentary yarn, which is very slick.

In the drawings and specication there has been set forth a preferred embodiment of the invention, .and although specic terms are employed, they are used in a generic and descriptive sense only, and not tor purposes o: limitation,

the scope'ot the invention being defined in the alined with each other and with their ends pointing in opposite directions, the rst strand having its end passing across and above the second strand and then crosswise beneath the second strand and being doubled back upon itself above both the second strand and the rst strand and the other strand having its free end crossed above the tree end oi.' the first strand,

the second strand having its tree end passed be- 15p l 4 neath the free end of the iirst strand and the main portion of the first strand and then the second strand having its free end passed above the body portion of the iirst strand and above the free end portion ot the rst strand and beneath the body portion of the second-strand to thus form a knot in which the second strand bites both the main body portion and the free end of thenrst strand and in which the first strand surrounds the second strand and has the body portion and the free end thereof disposed around the second strand to thus provide a non-slipping knot.
