lubricated ring structures heretofore employed.
lubricant pockets or reservoirs, sweeping ?oors,
cleaning and replacing oil-damaged equipment,
etc., is required. Moreover, more uniform yarn
tensions result, due probably to the uniform a'p- .
plication of lubricant secured. An important
advantage too, is the fact that the recirculated
oil is, in the course of its travel through the felt
wick, effectively ?ltered and there is reduced
tendency to gumming which heretofore has ne
cessitated frequent cleaning of the ring and
traveler.
As many widely different embodiments of my
invention can be made without departing from
the spirit and scope thereof, it is to be understood
that the invention is not limited except as de
?ned in the appended claims.
I claim:
1. A twister ring assembly comprising in com
bination a ring rail, a traveler ring mounted on
connecting said annulus with said pocket.
3. In a twister ring comprising a ring rail pro
vided with at least one pocket adapted to contain
lubricant, a traveler ring and means for conduct
ing lubricant from said pocket to the face of said
ring, the improvement which comprises an an
nulus of felt located immediately below and in
vertical alignment with said traveler ring, the
inside diameter of said annulus being slightly
greater than that of said traveler means, and
wicking connecting said annulus with said
pocket.
4. In a twister ring comprising a ring rail pro
vided with at least one pocket adapted to contain
lubricant, a traveler ring and means for conduct
ing lubricant from said pocket to the surface of
said ring, the improvement which comprises an
annulus of felt located immediately below and in
vertical alignment with said traveler ring, the
inside diameter of said annulus being slightly
the ring rail, means for conducting lubricant to
greater than that of said traveler means and a
the face of said traveler ring, lubricant collecting
means disposed immediately below said traveler 30 retaining means for said annulus removably at

coextensive with the inner wall of said annulus
