Patented May. 15,v 1934 UNITED STATES THREAD some 110mm Rudolf Etzkorn, Oberlin-rich,- Germany, assignor to American Glanmtoff Corporation, New York, N. Y., a corporation of Delaware Application September 16. 1931, Serial No. 563,206

3 Claim.

This invention relates to a novel thread guide holder.

In order to guide freshly spun filaments to suitable take-up means it is necessary that the friction of' the filaments and guiding means be maintained constant, and the stretching of the filaments uniform. If such results are not obtained the filaments will possess irregular tensile strength, elongation and irregular dyeing qualities. Much of the existing difliculties now encountered in leading the freshly spun filaments over an oscillating guide to suitable take-up or collecting means has been found to be due to the manner in which the thread guide is secured to the oscillating thread guide holder. A comparatively small amount of "play in the connection causes an uneveness in the stretching and the friction between the filaments, thus causing the above mentioned irregularities.

It is, therefore, an object of this invention to provide means whereby the thread guide may be securely fastened to the thread guide holder.

A further object of this invention is to provide means which will prevent any shifting of the thread guide in either a lateral or longitudinal direction with respect to the thread guide holder or support.

These and other objects of this invention will become more apparent from a perusal of the following description and a studyof the drawing in which: Figure 1 is a view partially in section of the holder for the thread guide;

Figure 2 is a front elevation of a second modification of the invention;

Figure 3 is a side elevation of the modification shown in Figure 2, a part of the holder being in section; and

Figure 4 is a section taken along the line 4-4 of Figure 2.

Referring now to the drawing and more particularly to Figure 1 there is shown a thread guide holder 1, usually secured to a suitable oscillating mechanism, having a bifurcated portion 2, 2. The furcations are provided with aligned bores 3, 4 and threaded recesses 5, 6 are formed concentric with each bore. means consists of a rod having a hook-shaped portion 7 at one end. The rod is held or locked in position in the bores by means of rubber stoppers 8, 9 compressed and held in position by By this construction the thread guide is fastened securely to the holder at two spacedpoints thuspreventing any lateral movement of the guide. Moreover there is very little longitudinal movement of the thread guide due to the security of the double holding or locking means.

In the modification shown in Figures 2, 3, and ithe thread guide holder 1 is formed with a The thread guiding Germany November 20,1930

depending portion'12. A groove 13 extends along both the depending and horizontal portion of the holder as is clearly shown in Figure 3. This groove'provides a seat for the thread guide rod which in this instance has in addition to a hook 7, a part 14 thereof, at right angles to the thread.

in their descriptive sense and not as terms of limitation, and it is intended that all equivalents "of these terms be included within the scope of the appended claims.

Having now set forth my invention as required by the'patent statutes, what I desire to claim is:

1. In combination a support having a bifurcation formed at one end each furcation having a bore formed therein and a threaded recess connecting with each bore, the said bores being in alignment, a thread guide rod having a hook. like member'at one end, positioned in the bores and means for holding the thread guide located in each recess comprising a stopper fitting around Q the thread guide and a nipple threaded in the recess, the pressure of the nipple against the said stopper being such as to hold the said thread guide rod in position.

2. In combination a support having a bifurca- J tion formed at one end each furcation having a bore formed therein and a recess connecting with each bore, the said bores being in alignment, a thread guide rod having a hook like member at one end, positioned in the bores and means for holding the thread guide located in each recess comprising a stopper fitting around the thread guide and a nipple secured in the recess, the pressure of the nipple against the said stopper being such as to hold the said thread guide rod in position.

3. In combination, a support having a bifurcated portion, a thread guide, holding means secured in said bifurcated portion to hold the thread guide from movement, said holding means including a compressible element.
