This invention. relates to an improved construction of ring traveler more particularly adapted for (use in twisting machines and an object of this invention isto-so' construct a traveler of this character that itwill be balanced to hang vertically on the rin r and yarn and therefore will float more freely and not cramp on the ring when rapidly revolved about the package on which the yarn is being wound.

. With these and other objects in view, the

inventionconsists of certain novel features of construction, as will be: more fully de-' scribed, and particularly pointed out in the In thea'c'company'ing drawings: t Figure 1 is a perspective'view showing my improved traveler as mounted on a vertical twisting ring.

. Figure 2 is an enlarged'perspe'ctiveview of my improved traveler;

Figure 3 shows thetra-veler; in vsectionas mounted on'a ring in section vwiththe yarn extendingthrough the traveler to the package. 1 I i 7 Figure 4 is a vlew showing-the ring 1n sec tion and my traveler mounted thereon.

Figure 5 shows the traveler partlally 1n 1 section and mounted on a rin a ortion of which is shown. v a V It is found in practice that the old style traveler for handling the heavier'yarns such as cord for cord tires andother heavy twisted yarns and the like is so ou'tof balance when running that it has a tendency'to swing or cant at an angle to the axis of the ring when running and so touch and scrape on the inside surface' of the ring thereby removing the lubricant therefrom and so materially increasing the dragging friction of the travelerwhich noticeably affects the quality of the yarn by stretching and destroying the elongation of the yarn and requires that the ring shall be much more frequently lubricated. To obviate these serious difliculties I have constructed a traveler whichhas a relatively straight shank portion to extend substantially in a straight line between the hook shaped end portions which engage the upper and the lower edges of the ring and I the ring. is in a vertlcal ipositionfiit doesnot tip or? i-have'fso constructed thelshankportion the traveler-that it is of a width substantially less than thatof either of its hook portions,

by which construction it willbe seenthat in order'to obtainthe required weight of traveler. I am enabled to extend the width and therefore increase the weight ofboth these top and bottom hook members.- While proportionately increasethe weightof the lower hook portionwhich increased weight willserve to cause the traveler to run in a vertical position while rapidly travelling about j i It will be seen that when" the traveler cant over and therefore the shank does not scrape the surface of, the ring to removethe portion, the suspension ofthe traveler. on

the yarn causes the traveler. to float aboutthering' with the result that-fa much better and more uniform twist and elongationis obtained and this traveling is controlledby Also the workingv life of thetraveler is increased and' the lubricant is required to be appliedmuch less" often than'when the .old

style of traveler is employed. The follow '80 c the addedweight rather than by friction.

ing is a'detailed description of the present? embodiment of my invention and showing one construction .of traveler bylwhichthese advantageous results may be accomplished:

With reference to the drawings, 10 .des1gnates the usual twlsting ring mounted inthe rail 11 so that the axis thru its center willbe vertical. A traveler. used in a twisting machine for instance such as is-employed to handle yarns 1n the form of a cord or other heavy twisted yarn used in the construction of so- -called:cord tires or shoesfor motor vehicles,

heavy ducks, etc, must be specially constructed for its work and in order thatlthesejtravel- 'ers shall stand up underthis heavy work-and Y function properly it is necessary that the traveler be so built or constructed as to hang 7 and not swingofiat an angle to this axis and so cramp its upper or its lower hook-shaped 7 surfaces upon the edges of the ring, thus retiming the dragging friction to the minimum and nicely controlling the twisting and winding effects of the yarn or cord as led upon the package or spool and to accomplish this in a simple and effective way, I have formed the traveler with a shank portion 12 which is sub- 'stantially straight, that is, it is not made in loop form and so is much less liable to tip and cramp and this shank portion serves to directly connect the upper hook shaped end portion I3'and the lower hook-shaped end portion 14, which hook-shaped ends are adapted to engage the corresponding upper and lower edges of the ring 10. I preferably form this travelerfrom a ribbon of stock having a uniform thickness, the stock being preferably rounding or oval in cross section as at 15.0n itsinner surface so that whenthis rounding surface is-in contact with the ring the contacting area will be reduced and so reduce to the minimum" any scraping or abrading action that this carrier may have upon the rmg "whencontacting with the same; also thls rounding surface reduces the abrading action on the yarn as it is drawn thereover. V I do not, however, limit myself tomaking the traveler with a rounded inner surface as this surfacemay be made flat, if desired.

s It isalso found to be of advantage to reduce the shank portion of the traveler throughout its length-and to reduce this materially so that its widthwill be substantially less than that of the hook-shaped end portions. The purpose of this reduction: is to reduce the weight and the frictional action ofthe traveler at its middleport-ion whereby in order to bring this traveler up to the required weight I am en- -abled to employ aheavier upper end 13 which is to be carried on the yarn and a substantially heavier lower end 14 which latter serves as arbalancing weight to maintain the traveler in vertical pos1t1on whlle runnlng. In. some lnstancesI may reduce the width of'this shank to substantially one-third that of the hook end portions.

In some instances al'soit is found of'advantage to ofiset the upper endof the shank portion. as at 16 outwardly fromtheplane of the backofv the shank to provide suflicient room forthe travelling yarn. Y

- In'my improved traveler the yarn 17 rides across the upper portion of the narrow shank fitthflp'OlHt 18 and the: shank 12 sets substantiallyparallel with the inner surface of the ring and the weight of the lower hook end14 is. sufficient to hold the travelerin a substantially upright position when running thereby preventing cramping and by being of the required weight this traveler floats on the yarn which is rapidly running through the same.

My improved traveler is preferably formed of a non-corrosive material such as bronze or the like and therefore does not require hardemng.

This traveler is extremely simple and practical in construction and is effective in its operation and by its use much less lubricant is necessary on the rings owing to the reduction of both friction and heat and also by its use both the spindle speed and production maybe materially increased and a better qualthe use of the old style traveler.

The foregoingdesoription is directed solely towards theconstruction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible,the invention being defined and limited only by the terms of the appended claims.

I claim-- I 1. A traveler for ring twisting adapted to run in a vertical position about its ring, the

same comprising relatively wide hook-shaped end portions, and a relatively narrow and sub-' stantially straight shank portion connectingsaid wide end portions, the: inner surface of tion connecting said wide end portions, the 1 inner surface of said traveler being convex. 3. A traveler for ring: twisting adapted to run in a vertlcal pos1t1on about its ring, said traveler comprising relatively widetop and bottom hook-shaped end portions, anda relatively narrow straight shank portion connecting said endportions,that portion where the shank joins thetop. hook portion having an abrupt yarn guiding shoulder,
