Patented Sept. 29, 1931 UNITED STATES PATENT OFFICE RHODE ISLAND, ASSIGNOR TO U. S. RING RHODE ISLAND, A CORPORATION OF RHODE RING TRAVELER Application filed February passes, and results in bringing 'the yarn in stricted a passage as to' cause brei.

too close proximity to the lubricated surface of the ring. In some cases the excessive outward tilting of the upper horn of the tra-veler relatively to the ring affords so reage of the yarn passing therethrough.

Furthermore, at present this type of traveler, when purposed for use upon relatively shallow or vertically short rings, is

made of excessive width in order to insure suiiicient weight. This relatively great breadth of the traveler body prevents an adequate approach of the latter to the concave wall of the ring, and lessens the effectiveness of traveler performance.

The essential objects of my invention are to overcome the overbalancing of the traveler top; to afford adequate weight for the traveler body without increasing the width of the latter; and to attain the above ends in a structure compact in form and inexpensive to construct.

To the above ends primarily, but not eX- clusively, my invention consists in such 5 parts and in such combinations of parts as fall within the scope of the appended claims.

In the accompanying drawings which form a part of this specification,

20, 1931. Serial No. 517,143.

Similar characters of reference indicate similar parts throughout the views.

In the drawings 8 represents a spinning or twister ring of any usual or convenient construction suitable for insertion in the ring rail of the spinning or twister frame.

My novel traveler, as shown in Figures 1 and 2, is of the vertical type, and is adapted for facile cutting and bending, by suitable tools, from a thin sheet metal blank. The out out metallic strip of material is bent to form a traveler comprising a shank represented in a general way by 10, including a lower portion 11 and a rearwardly and upwardly inclined portion 12 defined bv a bend or concavity 14, in this instance above the center of the shank.

The upper end of the shank portion 12 is continuous with the forwardly directed horn 16 including its usual downwardly inclined terminal lip portion 17, The slightly angular loop 18 formed by the horn portion 16 and the sha-nk portion 12 permits the passage therethrough of the thread or yarn 19 in its travel from the usual delivery rolls and thread guide to the spool or bobbin.

Integral with the lower end of the shank portion 11 is a forwardly extending arcuate upturned foot or lower horn 20. The material from which the traveler is formed is at the end of the foot folded rearwardly upon the lower face of the foot forming an integral strip 22 extending the length of the foot and connected to the latter by a closed loop or fold 23. rlhe width of the longitudinally disposed strip 22 is the same as that of the foot. The strip acts as a weight or a counterweight.

In operation, as the traveler is impelled in its annular course around the ring 8 under the impulse of the thread 19, the bearing portion 11 of its shank is held throughout its length in sliding Contact with the inner face 25 of the ring by virtue of the weight of the strip 22' which causes the shank portion 11 to assume a vertical position, thereby maintaining the thread bearing angle 18 of the traveler at a point rearwardly remote from the adjacent face 25 of the ring which is covered with a lubricant.

The eonnnon traveler ot' the prior art, differs from applicants present structure in the absence troni the toriner of the gravity ineinber or its equivalent. The. result is that the traveler assumes a forward tilt which brings the thread 19 closer to the lubricated surface oi' the ring than does applicants traveler.

A inodied lorni ot niy traveler, shown in Figure l, dii'lers 'lroni that disclosed in Figure l in that the strip QQ is lengthened to provide a portion 2T extending upwardly soine distance upon the rear tace of the shank portion; the strip portion Q7 being the saine width as that el the latter.

A further inediti-:iden ot the device is shown in Figure l, wherein the gravity strip at its upper end is laterally expanded to a width in excess of the width ot the traveler shank to torni a horizontal laterally projecting head Q9.

In all the forms ot' niy invention the added weight furnished by the strip is located upon the traveler at a point below the fulcruining point l-t thereof, which is above the medial point ot the shank l0.

In order to insure the desired perpendicular running position ot iny traveler it is desirable that the added weight furnished by n1y folded strip exceed the weight of' the upper horn.

The application ot the added weight by means ot a strip folded upon itselc is inexpensive and conipact.

I claim l. il traveler for spinning or twisting rings comprising a shank, a. liorn upon the upper end ot the shank, a "foot, and a grav ity strip upon the bottom ot the toot, extending inwardly troni the 'free end oi the foot.

2. A traveler for spinning or twisting rings comprising a shank, a horn upon the top ot the shank, a tootand a graif'ity strip extending longitudinally of the toot integrally connected to the tree end ot the foot,

3. A travel r Yfor spinning or twisting rings comprising a shank, a horn upon one end ot the shank, a 'loot upon the other end ot the shank, a gravity strip extending longitudinally ot the toot and in Contact therewith, and a told integrally connecting the toot and strip.

fl. In a traveler for spinning or twisting rings, a shank comprising a vertical portion and a rearwardly and upwardly inclined portion upon the vertical portion, a horn upon the inclined portion, a Jfoot upon the vertical portion, and a gravity strip upon thel foot extending inwardly troni the iree end ot the toot for counterbalaneing the horn.

5. In a traveler for spinning or tWisting rings, a shank comprising a vertical portion and a rearwardly and upwardly inclined portion continuous with the upper end ot the vertical portion, a horn upon the inclined portion, a foot upon the lower end of the vertical portion, and a gravity strip foldably connected with the foot extending longitudinally of the foot and engaging the vertical portion.

6. In a traveler tor spinning or twisting rings, a shank comprising a vertical lower portion and a rearwardly and upwardly' inclined upper portion, a horn upon the inclined portion, a toot upon the vertical portion, a gravity strip integral with the tree end ot' the foot extending longitudinally oi the foot and of the vertical portion of the shank, and a laterally projecting' head upon the upper end et the strip.

7. In a. trave er for spinning and twisting rings, a shank comprising a vertical portion and a rearwardly and upwardly inclined portion continuous with the upper end oi the vertical portion, a horn upon the inclined portion, a foot upon the lower end of the vertical portion, and a gravity strip foldably connected with the toot extending inwardly troni the free end of the foot.

In testimony whereof I have atlixed my signature.
