axial play of the traveler at during its rotation and the amount of this play is so adjusted relative to the width of the side bearing portions 9 which engage on the I flange 6 that the portionsof the flange contacting with such side bearing portions may sweep entirely across the side bearings, this action causing any accumulation of foreign material on the traveler to be wiped off by such relative lateral motion. The upper edge of the flange 6 is also very narrow and there is suflicient play laterally of the traveler within the ring to permit a like relative,

movement between theflange and the ears 10 so that acciiimulation of foreign matter tend- 'ing to clog the traveler at these points is prevented. l/Vith this construction the bearing points of the ring are reduced to very small areas so disposed that a laterally wiping action of the rotating traveler thereon is produced.- This small bearing area effectively eliminates much of the friction tending to retard the motion of the traveler and the wiplng action provides clean bearing surfaces where contact is made.

' Preferably the material of the base portion 1 and thesection 7 is cut away between the bearing portions 3, 8, and 10, as shown at 12 to permit a free passage for dirt or other foreign material between the ring and the traveler. The provision of the flange on the traveler not only makes it possible to provide the bearings on the ring as above described,.but materially stiffens the traveler so that it is prevented from being pulled out of the ring by'sudden jerks imparted thereto.

tion of gummy material or other foreign matter one or more cleaners may be employed, one construction of cleaner, as indicated in Figures 1 and 2, .comprising a strip of felt or similar fibrous material as 15 partially enclosed within a frame 16 which may be suspended at its upper end from' a bracket 17 fixed to or integral with thering, as shown this bracket being formed integral with the base portion 1. The

1 pivotal connection between the bracket and finger or wiper is so positioned that the wiper tends by gravity to press lightly To further insure against the accumulayarn through this eye and to the cop causes a pull to be exerted thereon in the direction toward the winding contact of the yarn on the cop. This is indicated by arrows in Figure 4, the arrow (4 indicating the direc tion of this pull when the bobbin is substantially empty and thearrows Z) and 0 indicating the line of action of this pull as the bobbin becomes successively more nearly filled. It is apparent that if the traveler is balanced while stationary without making provision tocompensate for this pull on the yarn eye it will be considerably out of balance in running condition due to this pull.

' One feature of this invention therefore relates to a construction of traveler by which this force applied by the yarn is somewhat neutralized. For this purpose the portion of the ring at the thread eye is made heavier than on the other side of the ring to bring its center of mass eccentric to its center of rotation so that centrifugal force set up by the unbalanced mass rotating eccentrically may counteract the pull exerted by the yarn on the eye. While de-' 'sirable results may be obtained by the use of an unbalanced mass located at the eye, as for example, by making the eye comparaa tively heavy, a better effect may. be obtained by locating the mass somewhat back of the eye in the direction of rotation as shown, for example, at the point 61 in Figure 4. The action of the traveler will be apparent from an inspection of this figure, in which, with the unbalanced mass located at the eye, the line of centrifugaliforce is in the direction indicated by the arrow 6, whereas the force exerted by the pull of the yarn is successively in the direction of the arrows (at, and c. If the center of this unbalanced mass islocated as shown at the point (Z, the centrifugal force acts in the line of the arrow f,

which it is seen is more nearly opposed to the direction of force exertedlby the pull of the yarn. As this direction of force Varies as the bobbin becoineswound itis apparent that it cannot be fully compensated for by a fixed unbalanced mass in the traveler, but its action may be materially improvedby the construction outlined so as to be in substantially rotation balance. The amount of unbalanced mass and its best location depend on the character and size of the strand, the speed of rotation of the traveler and I other factors, but with this construction the same traveler may be used successfully with a greater range of yarn sizes and speeds than can a traveler as ordinarily constructed.

A construction wherein the unbalanced mass is located at the eye is indicated in Figure 12 in which the traveler is formed withthe opening through the base eccentrically disposed-so vas toprovide a wider somewhat similar to Figure 4 in whiohtheunbalanced mess is located slightly. tozthe rear of the yarneye loya substantial iden- E in in inetalhc or other suitable socket ll ingot the base portion a zttthis vpoint.
