This invention relates to improvements in tex
tile working devices, and more particularly to a
roller guide to be used‘in place of guide eyes, etc.
on yarn winding, twisting and coating machines.

The roller guide of the instant invention consists '
of a roller adapted to rotate upon a stationary or,
rotatable axle and so constructed that it neither
picks up nor accumulates ?y thrown o? from the

culty has been experienced from yarn-?y build
61
ingup between the rolls and collars, which condi
30 tion eventually e?ects a binding action on the
roller guide, thus preventing the free turning of '
' the same. Due to the di?erence in friction be
tween the starting of the winding operation and
the ?nishing of said operation when employing
35 such yarn guide rollers as those now in use, there
is produced a yarn which is not uniform. This
lack of uniformity is due in part to a non-uni
form application of the treating material, if any
is applied, and to a non-uniform tension applied
40 to the yarn. By the use of a roller guide member
constructed in accordance with this invention, the
yarn is wound, twisted, etc. under an even ten
sion by virtue of the rolling friction, regardless
of‘the denier, speed or uniformity of the yarn.
45 Moreover, the construction of the roller guide is
such that it cannot become bound by ?y from
the yarn.
‘
In accordance with my invention, I construct
a roller guide to be applied to rewinding, twist
ing and other devices wherein the yarn travels
from one point to another, which roller guide is
adapted to be used in place of the pig tail guides,
porcelain eyes, porcelain or metal hooks and
other forms of stationary guide members, as well -
‘ The shaft it may be formed or have milled thereon
a shoulder 5 at one end thereof to accommodate 30
a bearing surface ii of the roller.
The opposite
end of the shaft ii from the shoulder 5 is threaded '
as at l to accommodate a bearing sleeve 8. The '
bearing sleeve 8 may be a piece of tubing hard
ened at least at its inner end to act as a bearing,
which .tubehas internal threads adapting it to
be threaded on to the shaft 5, thereby forming
another bearing 9 adapted to accommodate the
bearing surface ii of the roller. That part of
the shaft 5 lying between‘ the bearing tube'3 ‘and 40
the shoulder 5 may be formed of such a diameter
with reference to the axial hole in the roller
that the shaft and roller do not contact. If de
sired, and in certain cases it is preferable, that
both ends of the shaft 5 be threaded in a. manner
similar to that shown in the drawing at ‘l and
both bearing surfaces may be formed from a
tube or sleeve similar to tube 8. I When tubes are
employed as both bearing surfaces, they may be
formed of pressed cellulosic materials to eliminate
the use of oil which is necessary to prevent a
binding action of metal against metal. The
pressed ,cellulosic tubes may be formed of cellu
