J. W. DUB OIS RING TRAVELER Nov. 14, 1967 Filed Oct. 7, 1966 INVENTOR dosEPH W Dusors 2 ATTORNEY United States Patent ABSTRACT OF THE DISCLQSURE A traveler for the rings of spinning or twisting frames having a pair of vertically aligned and integrally formed bow elements the lower of which serves to guide said traveler while moving about said ring and the upper for maintaining the yarn guided thereby entrapped during the entire cycle of spinning or twisting.

This invention pertains to travelers for ring spinning or twisting frames and more particularly to improvements in the conformation of the travelers for maintaining control of the yarn during a dolf or during any period of machine stoppage.

During the period of a deft, prior to a start-up, the height of the ring rail is often changed and may cause a slackening of the previously spun yarn. The yarn extending through the traveler to the base of the spindle has had twist applied so that when the tension is removed, it will tend to untwist in a curling, loop forming motion. This activity often unthreads the traveler, causing endsdown which result in additional manual labor for rethreading the travelers. Any increase in the down-time of the machine is to be avoided if possible as the unit cost of production is similarly increased. The instant invention is directed toward eliminating the problem of traveler unthreading.

It is a general object of the invention to provide a ring traveler which will, in any unsupported position on the ring flange, entrap the yarn.

It is a further object of the invention to provide a traveler having two circumferential lock points for entrapping the yarn therebetween.

It is another object of the invention to provide a traveler having a ring flange encircling bow and a vertically disposed yarn bow.

It is a still further object of the invention to provide a traveler which may be applied easily to the ring flange.

These and other objects will become apparent as further details are disclosed. The invention will be described by reference to a specific embodiment as illustrated in the accompanying figures of drawing, wherein:

FIG. 1 is an elevation of a bobbin in a spinning ring with the yarn drawn through the traveler in preparation for start-up;

FIG. 2 is a vertical section of a portion of the ring with the traveler in a spinning position; and

FIG. 3 is similar to FIG. 2 showing the traveler in an unsupported position.

Now referring to the drawings, a spindle and bobbin 21 are adapted to be driven by a continuous tape 22 in a known manner. The bobbin 21 projects through a ring rail 23 and a ring 24 which has a smooth upper horizontal flange 25. The ring may also have a similar lower flange 26 for use in a reversed position to double the period of use. A strand of yarn 27 extends downwardly from a supplying source, as for example drafting rolls (not shown). The yarn 27 is threaded through a traveler, generally designated 28, and inwardly of the ring 24 to the base of the spindle 20 where a few loops 29 firmly secure the end.

The traveler 28 has an upper bow portion 30, which in 3am? Patented Nov. 1 1967 the preferred embodiment takes a generally elliptical form; however, this may also be circular or angular formation. The bow portion 30 at its base continues into two

shoulders

31 and 32 of equal length and spaced apart from each other a distance considerably less than the width of the flange 25. The traveler 28 may be made from flat wire stock or of any other suitable material and may be of unitary construction as shown.

Vertically aligned with the bow 30 are two outwardly

arcuated horns

33 and 34 extending downwardly from the

shoulders

31 and 32, respectively. As shown in FIG. 2, the

horns

33 and 34 may be integral with the bow 30 by being bent reversely upon the

shoulders

31 and 32 and arcuated generally elliptically. The

horns

33 and 34 terminate in opposing ends 35 and 36 separated from each other sufficiently to lock about the flange 25. Application of the traveler 28 is made by springing the ends 35 and 36 apart as they are pressed over the flange 25. There is less possibility of travel breakage at application because of the double spring action of the combination of the how 30 and the

horns

33 and 34. The conformation of the traveler is that of a lower flange-encircling portion in tangential relationship with an upper yarn-controlling portion.

In operation the yarn 27 is threaded through the bow 30 to the base of the spindle 25), then as the rail 23 is raised and the spindle rotated the yarn will build up upon the bobbin. Previous to the dotf a few more loops are allowed to form upon the spindle to lock the yarn while the bobbin is removed. An empty bobbin is applied and the rail is raised in preparation for starting up. This allows the yarn to slacken and twist into loops which may work free from the traveler unless restrained in some manner. In the instant invention, slackening of the yarn will drop the traveler to the flange 25 with both

shoulders

31 and 32 in contact therewith. No matter at what angle the traveler may drop both shoulders will contact the flange and entrap the filling within the bow 30. The traveler herein provides constant control of the yarn during any period of machine shut-down and greatly reduces the manual operation connected with ends-down.

While one embodiment of the invention has been disclosed, it is to be understood that the inventive concept may be carried out in a number of ways. This invention is, therefore, not to be limited to the precise details described, but is intended to embrace all variations and modifications thereof falling within the spirit of the invention and the scope of the claims.

-I claim:

1. A traveler for a ring having a horizontally disposed flange which includes a bow, said bow terminating in a pair of opposed shoulders disposed in spaced and aligned relation, and an arcuated horn member extending downwardly from each of said shoulders in the same plane as said bow for encircling said flange.

2. A traveler as set forth in claim 1 wherein the horn members are integrally formed in vertically aligned relation with said shoulders and bow and are separately disposed in general elliptical formation with the ends thereof having a distance therebetween less than the width of said flange.

Claims

1. A TRAVELER FOR A RING HAVING A HORIZONTAL DISPOSED FLANGE WHICH INCLUDES A BOW, AND BOW TERMINATING IN A PAIR OF OPPOSED SHOULDERS DISPOSED IN SPACED AND ALIGNED RELATION, AND AN ARCUATED HORN MEMBER EXTENDING DOWNWARDLY FROM EACH OF SAID SHOULDERS IN THE SAME PLANE AS SAID BOW FOR ENCIRCLING SAID FLANGE.

2. A TRAVELER AS SET FORTH IN CLAIM 1 WHEREIN THE HORN MEMBERS ARE INTEGRALLY FORMED IN VERTICALLY ALIGNED RELATION WITH SAID SHOULDERS AND BOW ARE SEPARATELY DISPOSED IN GENERAL ELLIPTICAL FORMATION WITH THE ENDS THEREOF HAVING A DISTANCE THEREBETWEEN LESS THAN THE WIDTH OF SAID FLANGE.
