3 -Claims.-. (Cl. :57 -125Z) This invention relates to spinning or twisting andmore particularly to the ring and traveler fora spinning or twistingoperation.

In one type of spinning or twisting, a ring encircles the take upv package and yarnis delivered to the .package through a traveler which moves about the ring so as to guide the yarn onto the package. of the spinning. operation and require replacement as they become worn; The wear of a travelerv usually occurs at the point of contact of the traveler with the ring or at the point of contact of the yarn with the traveler. The particular characteristics of the traveler will cause varying tensions upon the yarn and the particular characteristics of the traveler must be chosen for each type and count of yarn which is being worked upon. Good traveler operation produces a better quality of yarn than if the traveler is improperly used or if a traveler is used which has become unduly worn. The particular position that the traveler assumes on the ring while running is also of importance as in some positions a traveler will produce less drag and less wear than were the traveler not properly balanced.

One of the objects of this invention is to provide a traveler which will engage the ring at a single point.

Another object of this invention is to provide a traveler which will be so balanced that the innermost horn of the traveler only will engage the ring while running.

Another object of this invention is to provide a traveler which will locate the yarn at such a position that it will support the traveler to cause it to be well balanced with reference to its position on the ring.

Another object of this invention is to provide a traveler which will assume a position substantially radial of the ring during the running of the traveler at the desired speed.

Another object of this invention is to provide a traveler which will be symmetrical so that it will be immaterial which horn of the traveler is placed innermost with reference to the ring.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a top plan view illustrating a ring with a traveler thereon and showing a package as provided at the center of the ring;

In proceeding with this .invention, I provide a traveler having horns to extend beneath the flangeiof the' ringxwhich are: insubstantial ali rnentq: A body: portion of t the traveler connects the-horns and" is: arranged somewhat in theform of 2 'anfrustoepyramid;having the two sides inclined toward each other and extending upwardly with a fiat top at the upper central portion of the body. By this arrangement I locate the position of travel of the yarn through the traveler and provide a symmetrical traveler which may be positioned with either of the horns innermost and. one which will be so supported that only the inner horn will contact the ring which contact will be below the flange and usually at a point spaced from the post of the ring.

With reference to the drawings, I0 designates a take up package for yarn II. A ring l2 encircles the package and consists of a post l3 having an upper flange l4 and a lower flange l5. The traveler which is snapped over the upper flange I4 is designated generally l6 and is shown in perspective in Fig. 4.

This traveler is of uniform cross section and is made of different widths depending upon the weight of traveler desired. The traveler comprises horns I! which extend toward each other in substantial alignment. Connecting these two horns there is a body portion designated l8 comprising upwardly inclined sides l9 and a central part 20 which is also fiat and makes an obtuse angle with the opposite sides l9 while these sides are arranged at an acute angle to the alignment of the horns H. In some cases instead of the sides l9 extending downwardly to provide a sharp bend 20 with the horns H as shown in Fig, 4, the sides now designated 2| and shown in Fig. 5 are joined to the horns H by a vertical portion 22 as shown in Fig. 5.

When either of the travelers such as above just described are snapped over the flanges M of the ring and the yarn ll passes through the traveler with the traveler operating at a high rate of speed such for instance as ten thousand revolutions per minute there is a centrifugal force tending to move that traveler outwardly which is designated in Fig. 2 at 23 while there is a further force designated in Fig. 3 as 24 tending to lift the traveler upwardly and a force designated 25 in Fig. 2 tending to move the traveler inwardly, which latter two forces are caused by the pull of the yarn. The force 24 causes the traveler to lift sufliciently so that there is a space 2 6 through which the yarn may extend. The forces 23 and 25 are in sufiicient balance so that the traveler moves outwardly leaving its outer horn ll free of the ring (see Fig. 3) while its inner horn l1 contacts as at 2'! the under surface of the inner flange H of the ring which by reason of the balance of the traveler and these forces which are acting is the only point which this traveler contacts with the ring in its engagement.

The location of the obtuse angle formed between the parts l9 and 20 and which is designated 28 is located substantially above the inner horn ll of the traveler so that the yarn supports the ring in a position to have only this point 21 to contact the ring. This point is important Joecause of the location of the support which the yarn gives to the traveler in its movement, and it is quite definitely located because of the inclined inner side IQ of the traveler. Some oscillation or movement of the yarn will occur along this obtuse portion sufiicient so that the wear will not become localized. This will occur in the form shown in either Fig. 4 or 5.

I claim:

1. A ring traveler of uniform cross section for a horizontal ring comprising horns extending inwardly toward each other in substantial alignment and a bow portion joining said horns with a central portion parallel to said horns and straight side portions joining said central portion and horns, said straight side portions being at an obtuse angle to said center portion and at an acute angle to said horns.

2. A ring traveler as set forth in claim 1 wherein said traveler is symmetrical with relation to a center line between and perpendicular to said horns.

3. A ring traveler as set forth in claim 1 wherein said horns each extend inwardly to a point substantially vertically below the junction of said central and side portions.
