DE ISLAND, ASSIGNOB TO VICTOR SHAW RING TRAVELER COMPANY, OF PROVIDENCE, RHODE ISLAND, A. CORPORATION OF RHODE ISLAND.

RING-TRAVELER.

Application filed June 29,1914. Serial No. 847,872.

To all whom it may concern Be it known that I, WILGER T. LANCASTER; a citizen of the United States of America, and a resident of Ashton, in the State of Rhode Island, have invented a new and useful Improvement in Ring-Travelers. of which the following is a specification.

This invention relates to travelers for ring spinning; and it consists in a beveltop ring traveler of improved construction. and in the combination of the same with a horizontally flanged ring as hereinafter particularly described and claimed.

In common with numerous previous improvements, the bevel-top traveler of the present invention. is an improvement on the ordinary C-shaped traveler, the patents for which have expired; and said bevel-top traveler is therefore shown in contrast to said C-shaped traveler in the drawings-hereinafter referred to.

The leading objects of this invention are: to reduce the length of the material in the traveler, so as to add the weight of the length saved in greater thickness of metal for longer wear; to render the improved traveler better balanced from the contact or bearing at its inner horn, where centrifugal force throws it against the inner flange of the ring; to adapt the improved traveler to wear flatter or more evenly at this point of primary. ring contact or hearing; and to adapt the improved traveler to be kept in a horizontal or balanced position with a. lighter strain upon the thread than has heretofore been practicable.

Other objects will be set forth in the general description, which follows.

A sheet of drawings accompanies this specification as part thereof.

Figures 1 and 2 are conventional elevations partly in section showing an improved bevel-top traveler in contrast with a C- shaped traveler at the beginning and end of a ring spinning operation, respectively; Fig. 3 represents a magnified section through an I-shaped ring, showing the said improved traveler on a larger scale.

Like reference characters refer parts in all the figures.

The horizontally flanged ring represented at a is of an ordinary I section. See Fig. 3. The bevel-top traveler I) combined therewith is of improved construction. An ordinary C-shaped traveler is represented by to like Specification of Letters Patent.

way of contrast at 0. An ordinary bobbin is represented at (Z; the thread eye at e, and one and the same thread running from the thread eye 6 through the traveler b or 0 to the bobbin d, is represented at f.

The improved bevel-top traveler b, as

compared with the C-shaped traveler 0, ob-

viously requires a considerably reduced lengthof the ordinary metal from which its blank is cut; and can consequently be made of a given weight from thicker material, so as to wear longer. The same is true to a greater or less extent of the improved traveler as compared with travelers of other known forms. In so reducing the length of the metal, the improved traveler is given the bevel-top shape represented in the several figures. In Fig. 3 its inner and outer contact horns are represented at 1 and 2, respectively; its bevel top at 3, and its outwardly rounded side or end portions connecting said bevel top with said horns 1 and 2 respectively, are represented at 4 and 5. The horns l and 2 are in line with each other and normally horizontal. The inner horn 1 adjoins the larger and heavier rounded portion 4. The outer horn 2 is about one-third longer than the inner born, but the outer side of the traveler including the smaller curved portion 5 is lighter than the inner side, being reduced in weight about one-third as compared with said inner side. One effect of so reducing the outer side of the improved traveler 6 between its outer horn 2 and its bevel top 3 is to adapt the improved traveler to find and maintain an effective balancing position without any'contact of the outer horn 2 with thering. Previous travelers as represented at a drop down more or less at the outer side, and occasionally the outer horn comes in contact with the outer side of the rim a, and sometimes rubs so hard under centrifugal force as to cut into the side of the ring I or to draw the temper of the traveler.

The improved bevel-top traveler b is designed and adapted to run in the balanced position in which it .is shown in the accompanying drawings, whether the bobbin be empty as in Fig. 1 or full as in Fig. 2, and whether the ring be in its uppermost position, as shown at the top in each of these figures, or in its lowermost position, represented at the bottom in Figs. 1 and 2. In said balanced position, the horns 1 and 2 of the bevel-top traveler b are horizontal as thread f keeping the. entire length of said inner horn 1 in contact with said ring flange 1. All the rest of the improved traveler,

in its said balanced position, vis free from contact with the ring, and the revolving traveler is thus adapted to run lighter and smoother, as well as with a flatter and consequently a longer Wear, as compared with said previous forms represented at e. Owing to said saving-in wear, a given weight of the im roved bevel-top traveler will last 100% onger as compared with said old forms; and running lighter, weight for weight, makes it possible to run travelers three or four numbers heavier-than is possible withother forms for agiven size of thread; a relatively light strain on the thread sufiicing to control a givenweight of traveler. Insuring a flat wear on the inner horn 1 of the improve'dtraveler b is also advantageous in new of the fact that the uneven wear of the-inner horn due to the tilting over of old forms of traveler at the outer side of the ring a, as represented at. 0, extends into' the bend between the inner horn and the inner side vof the traveler, .where strength is most essential; and sometimes to those portions of the inner side of the traveler which contact with the thread, causing. them to cut the thread.

The extremity ofthe elongated outer horn 2 contacting with the outer side of the ring a prevents the reducedside or end5 of the improved traveler b from coming in contact with the outer flange 2 of the ring'at the instant when the 'splnning machine 1s bein stopped or started and the traveler'is pulle inward by the thread. At all other times traveler isthrown outward by j centrifugal orce; When so pulled inward,

reduced traveler would bind by contact'w-ith at the instant of stopping or starting, thesaid outer flange 2', but for the endwise contact of said elongated outer horn 2.

Having thus described saidimprovement,

I claim as my invention, and desireto patent under this specification.

1. improved ring traveler having an 7 inner horn adaptedto form .itswprimary ring contact, an outer horn of greater length, an outwardly curved portion connecting said inner horn with said bevel top and adapted to'contactwith the thread, and an outwardly curved portion connectsaid outer horn with sald bevel top and in reduced relatively'to the curved portionfirst named;

2. In combination with --a horizontally flanged ring, a normally balanced bevel-top ring traveler having an inner wear-determining horn adapted to contact flatwise' with the inner'flange of the ring, and an outer horn of greater length adapted to contact endwise with the ring when the traveler is not balanced by centrifugal force.

3. In combination with a ring of I-section,

a bevel-to ring traveler, normally balanced by centritugal force and the pull of the thread, said traveler having an 1111181 weardetermining horn adapted to contact flatwise with the inner flange of the ring, an 5 outer horn of greater length adapted to contact endwise with the ring when the traveler is starting or stopping, an outwardly curved portion .connectlng said: inner horn with said bevel top and adapted to contact with I the thread, and an outwardly curved re- 7 duced portion. connecting said outer. horn with said bevel tOP':
