Patented Feb. 23, 1932 UNITED STATES PATENT OFFICE EDWIN R. JEROME, OF ORANSTON, RHODE ISLAND, ASSIGNOR 'I'O VICTOR RING TRAVELER COMPANY, A. CORPORATION OF RHODE ISLAND RING- T RAYELER Application filed February 24, 1931'. Serial No. 517,793.

This invention relates to a ring traveler of the type used in ring twisting or s inning, which operates about a horizontal ange of the ring; and has for its object to reduce the friction of the traveler on the ring thus reducing Wear on both the traveler and the ring.

A further object of the invention is to produce a traveler which will cause an even tension on the yarn Without strain on the yarn thus producing an evener yarn and one of improved quality.

A further object of the invention is the provision of a traveler which will permit of traverse motion of the yarn along the traveler to prevent the yarn from cutting the traveler in a single place. I

A still further object of the invention is the provision of a balance between the traveler, the tension of the yarn extending therethrough and centrifugal force so as to cause the traveler to substantially float aroundthe ring with a minimum amount of friction upon the ring and with tipping and jamming of the traveler practically eliminated.

With these and other objects and advantageous features in view, the invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompany- 30 ing drawings, and more particularly set forth in the appended claims.

In the drawings:

Fig. 1 is a side elevation partially diagrammatic, showing the ring traveler positioned about a bobbin with the yarn leading from the draft rolls thereto;

Fig. 2 is a perspective view of the traveler;

Figs. 3, land 5 are sectional views showing the relative positions of the traveler and ring at different positionsot the rail with respect to the bobbin, in which three positions difi erent amounts of ballooning of the yarn take place. g

d in ring spinning and twisting oithe type where a traveler used to traverse a horizontal flange of the ring, the shank of the traveler has usually been on the arc of a circle and the trav contacts with the ring at two or more pt its in its movement, commonly on cutside oi? the web and outside of the flange of the ring thereby causing considerable friction or drag of the traveler on the ring and necessitating wear and heat which shortens the life oi the traveler and detrimentally affects the ring, particularly at high speed operations. Further, the tension on the yarn is increased both between the traveler and the front draft roll and the traveler and the bobbin, but I have found that by so shaping and weighting the travn eler as to balance the yarn tension against the centrifugal force the traveler substantially floats about the ring and is guided 'in its travel by but one point of contact with the ring thus causing the yarn to carr the weight of the traveler and cause less friction on the ring thus'increasing the life of the traveler to a material extent, and I have found that one traveler design which will meet with these requirements has this single point of contact with the ring just above and adjacent to the inner horn of the traveler, whereby the traveler is guided by said contact with the inner edge of the ring and the yarn supports a large portion of the weight thereof and the friction is for practical purposes negligible; and the following is a detailed de scription of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished.

Travelers of the type herein described heretofore have been formed with horns connected by a substantially circular shank portion and variations in travelers have been made by varying the size of the circular shank. l have provided a traveler in which, with reference to the drawings, the horns 10 and 11 are straight and in substantially a single plane for a portion of their length and are connected by an elliptical shank 12 which is sub stantially the shape of the top of the flange 13 of the common ring 14.

Tension of the yarn exists between the front draft roll and the traveler (see l) and between the traveler and the bobbin. As the traveler ismoved rapidly about the ring centrifugal force tends to move the traveler radially outwardly of the ring and in order to compensate these two forces, 1 have prov vided a traveler so weighted as to balance these forces, and substantially float about the ring being guided by contact with but a single point thereon.

In operation about the ring, the centrifugal force causes the traveler to contact on the in ner edge of the ring at point 15 located just above the horns 10 and 11, a substantial portion of the weight of the traveler from the point of contact 15 around to the horn 11 will be supported by the yarn 16 regardless of the various positions of the yarn 16 therealong and cause the traveler to float clear of the ring flange 13 except for this single point of contact 15, which point 15 is located in a horizontal plane passing through the center of the flange.

By this arrangement the traveler will run substantially vertically and the weight of the traveler itself will cause the tension on the yarn rather than friction of the traveler on the ring, an even tension is maintained on the yarn at all diameters of the bobbin between empty and full and at all positions of the ring rail and consequently more even and better yarn is obtained and more yards of the yarn of a given size may be produced.

The traveler is so shaped as to permit a traverse of the yarn along the shank thereof, three positions of which I have illustrated in Figures 3, 4 and 5 at either point 17, point 18 or point 19 along the shank. These different positions will be carried by the different relative positions of the yarn and traveler when the ring and rail are at the uppermost position of their travel the least ballooning will occur as in Figure 3, where as when at the lowermost position of its travel greatest ballooning will occur as in Figure 5, while Figure 4 shows an intermediate position of the rail substantially at its middle position of its travel, as shown in Figure 1; thus, by providing a flat curvature substantially along the line of an ellipse, the yarn 16 will traverse along the shank portionof the traveler from the point 17 to the point 19, prevent the yarn from cutting the traveler at any one point, and thus abrading the yarn during operation. During this travel, the yarn runs clear of the ring at all times.

By the use of my improved traveler, l have increased the life of its operation several hundred per cent, with less wear on the ring and have provided a traveler which may be used with higher speed spindles, also making a better quality of yarn.

i l hile l have described certain construction forms which embody the principles of my invention, it is obvious that other desi changes in arrangement may be made and scope 2 e appended cla weaves having horns extending beneath the ring flange, and a continuously curved shank portion connecting said horns shaped and weighted with respect to the pull of the yarn guided therethrough, and centrifugal force acting thereon so as to substantially float about the ring and be guided by contact with the ring at a single point only when in operation.

2. A traveler for a horizontal ring flange having horns extending beneath the ring flange, and a continuously curved shank portion connecting said horns shaped and weighted with respect to the pull of the yarn guided. therethrough, and centrifugal force acting thereon so as to contact with the ring at the lower inside edge of the shank only when in operation.

A traveler for a horizontal rin flange having horns extending beneath t 1e ring flange, and a continuously curved shank portion connectin said horns shaped and weighted with respect to the pull of the yarn guided therethrough, and centrifugal force acting thereon so as to contact with .the ring at a single point above the born when in operation.
