Application May 1, 1937, Serial No. 140,256

4 Claims.

This invention relates to ring travelers for spinning machines.

Ring travelers when in operation on a spinning machine travel at avery fast rate of speed around 5 the ring and when sotraveling the traveler floats or has practically no contact with the ring.

Various traveler cross sections have been proposed and used, such for instance as round, flat and half-oval, that is oval on one side and flat on the other.

The invention has for its salient object to provide a traveler so designed as to cross section as to reduce the air resistance on the traveler to a minimum. I

Another object of the invention is to provide a traveler having a cross section so designed as to offset the pull of the yarn on the traveler and improve the balance thereof.

Another object of the invention is to provide a traveler having a cross section so designed as to improve the balance of the traveler in operation, thus causing the traveler to run in a true circle around the ring instead of being ofl'set due to the pull of the yarn thereon.

Further objects of the invention will appear from the following specification taken in connection with the drawing which forms apart of this application, and in which I Fig. 1 is a sectional elevation of a ring having mounted thereon a traveler constructed in accordance with the invention;

Fig. 2 is a transverse sectional elevation taken substantially on line 2-- 2 of Fig. 1; and

Fig. 3 is a sectional elevation showing a. slightly different cross section from that shown in Fig. 2. p

In the embodiment of the invention illustrated in the drawing there is shown a traveler III which may be of any desired form or shape, and in the form illustrated has hooks. and 12 formed on the ends thereoi. for embracing the spinning ring l3. The yarn Y is shown as leading downwardly to the traveler l0, passing under the traveler at l5 and being led to a bobbin or spool S.

reaches the traveler in substantially a vertical perpendicular position and leaves the traveler in a substantially horizontal direction. This places an uneven tension against the traveler when the traveler is balanced equally on both sides of a vertical plane passing through the longitudinal center line of the traveler. This unequal tension causes the traveler which moves around the ring at a very high rate of speed to run partially sidewise" instead of in a true circle. In order to overcome this condition the cross section of the traveler constructed in accordance with the invention is so designed as to offset this uneven pull by so distributing the weight that the greater portion of the weight is disposed on In the usual construction of traveler the yarn one side of the vertical plane mentioned, thus causing the traveler to run in a true circle free from friction against the ring.

In the embodiment of the invention shown in Fig. 3 the cross section of the traveler is ovoid or egg'shaped.

In the form of the invention shown in Fig. 2 the cross section is in the shape of a flattened ovoid having three

flattened sides

20, 2| and 22, the sides 2| and 22 tapering toward each other at one end and being connected by a curved or rounded end portion 23.

It will be understood that the traveler for a regular twist runs in one direction on the ring and for a reverse twist runs in the opposite direction. The cross section for these two operations will be reversed-, i. e., the heavier side or edge will be at one side for the regular twist traveler and at the other side or edge for the reverse twist. In both cases the weight will be greater for the trailing edge, in the direction of travel, than for the advance edge.

By reason of the construction above described, a, much better balance is maintained during the operation of the traveler, thus causing the traveler to run in a true circle, eliminating friction between the traveler and the ring and providing a construction which will have a much longer life than the travelers now in general use. Furthermore, this type of traveler will produce yarns of higher quality on account of the decrease in friction between the yarn and the traveler.

Although certain specific embodiments of the invention have been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope oi. the invention, as expressed in the following claims.

What I claim is:

1. A ring traveler having an ovoid cross section, the largest end of the ovoid being disposed at the trailing edge of the traveler.

2. A ring traveler having a cross section so designed that the weight of the portion of the traveler at the trailing side of the vertical center line thereof will be greater than the weight on the other side of the center line.

3. A ring traveler having a flattened ovoid cross section, the largest end. of the ovoid being disposed at the trailing edge of the traveler.

4. A ring traveler having a cross section so designed that the weight of the portion of the traveler on the trailing edge thereof will be greater than the weight on the advance edge thereof.
