THREAD T11.

Application ined` August 2, l1923. seriai N'. s553499.

This invention relates to stiffened thread tips designed to avoid the necessity of using needles for threading beads, gems or the like.

In order to thread beads or gems upon a silk cord in the ordinary manner a needle the eyes or passages in said beads or gems, and as said eyes or passages are often oi irregular size, many valuable beads or gems have been destroyed as the result of trying to force a needle therethrough. Sometimes the eye in a bead is barely large enough to permit the passage of the needle, but the protruding portions of the cord threaded through the eye of the needle obstruct said eye and results in the cutting of the cord. By forming a stiffened tip on the end of the cord, the use of a needle is rendered unnecessary and the breaking of beads and cutting of the cord in the ways just men` 3o tioned are avoided.

A special object of this invention is to provide a stiifened thread tip which will not be apt to fray out at the end. Then a twisted silk cord, such as is generally used for threading beads and gems, has its end simply hardened or stifened, as has heretoyfore been done, the ends of the strands of cord will soon fray out after being threaded through a number of beads, and it is obvious that when so frayed the end of the tip will obstruct the passage of the cord through the eyes of the beads and greatly interfere with, or completely prevent, the further use of said cord. This fraying of the end of the tip is eliminated in the pres ent invention by folding back. a substantial portion of the thread upon itself and twisting said overlapping portions together before the stiffening agent hardens the tip.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined in the claims at the end of the description. V

is required for conducting the cord through ln the accompanying drawings, wherein similar referene .Chaiaters are used te designate corresponding parts throughout theseveral views: f

','Figure l is an enlarged viewof the end portion of a threading cord having a stiffened tip formed thereon substantially in accordance with this invention.

`Figure 2 is a similar view showing an` intermediate stage in the formation of the tip. p

Figure 3 is a similar view of a cord having a modified form of stilfened tip.

Figure 4f is a view of the same form of v tip shown in Figure 3 but illustrating how the ends of the tip becomes frayed in use.

Referring first to Figures 1 and 2 of the drawing, l designates an ordinary twisted silk cord such as is used for threading beads and gems for making necklaces. In forming the stiffened tip 2` on said cord, the end `portion 3 thereof is folded back, as illustrated in `Figure '2, and the. overlapping portions are then twisted as shown in Figure l. They portion of the thread from which the tip is formed is saturated with a suitable stiflening liquid, such as a solution of starch, gum arabic, shellac, or glue, which will harden when exposed to the atmosphere, kbefore the extremity 3 is folded back upon the cord l preparatory to twisting the tip into the form shown in Figure l. After the tip is thus formed, it is allowed to harden before the cord is used. When said tip has become hard and stiff, it will serve ,to conduct the cord through the eyes or passages in beads or gems without the use of a needle and without causing said tip to fray at its end.

The end of the folded and twisted tip is not apt to fray because the ends of the strands from which the cord is made are not disposed at the end of the tip in this construction, as they are in the form of the tip illustrated in Figures 3 and 4. In the latter figures, the end of the cord 4 is simply saturated with the stilfening liquid and allowed to harden in forming the tip '5, so that the ends of the'strands composing ping yportions twisted together, said tip being' stiffened substantially as described.

2. A thread composed of twisted strands and having its end portion folded back upon itself, the overlapping portions being twisted together to form a tip, said tip being stit'fened substantially as described.

3. A thread composed of twisted strands and having its end portion folded back upon itself, the overlapping portions being twisted together to form a tip, said tip being Astiifened substantially as described, the end of the tip being thus formed by the fold of the thread and the ends of the strands composing the thread being arranged at a distance from said tip end.

4. A method of forming a thread tip, which consists in saturating the end portion of the thread with a stifening mixture, folding the extremity of said saturated portion backward upon itself, twisting said overlapping portions together, and allowing said twisted tip to be hardened by the setting of the stiiening mixture.

In testimony whereof l have signed my name to this specification.
