Britain. "IMPROVEMENTS IN MACHINERY USED IN THE MANUFACTURE OR TREAT-
MENT OF THREAD."
This Invention relates to machinery used in the manufacture or treatment of
thread, and according to the system in which the thread is beamed like warp yarn.
One improvement is applicable to the machines used for dressing and polishing
the thread, in which machines the thread drawn off a beam at one end is treated
with starch or other dressing material, and is subsequently acted upon by well
known drying and polishing apparatus, being guided through the machine by
various rollers, and finally passing to winding machinery, or being re-wound on a
beam to be transferred to winding machinery or to other beams. When proceeding
through the dressing and polishing machine, the thread whilst in a wet or only
partly dried condition passes over metal rollers, which are grooved circularly for
the purpose of separating the individual threads from each other, and are made to
reciprocate in the direction of their length so as to roll the thread, and prevent its
being unequally acted on. In dealing with certain varieties of thread these grooved
guide rollers bave given considerable trouble that has hitherto baffled numerous
attempts to overcome it, in consequence of the grooves becoming clogged with the
dressing material. By the present Invention the inconvenience is avoided in a
simple and complete manner by applying to the side of each grooved roller opposite
to that where the thread passes in contact with it, a bar of wood or other suitable
material, which is either originally made to fit the grooves or very soon becomes
worn by the roller itself so as to fit the grooves, and which bar keeping its position
whilst the roller revolves effectually cleans the grooves. The bar is so connected to
the roller as to partake of the longitudinal reciprocation of the latter.
A second improvement is applicable in the case of certain varieties of thread to
the apparatus for beaming the thread, that is, for winding it in the "warp" form
for the dressing and polishing machine; and this improvement consists in employing
a swinging brush to act intermittently on the threads; in order to separate the

page_text: individual threads when they are liable to cling to each other from their twist or
from any other cause. The brush is, by preference, arranged in a transverse position
under the line of threads, being carried by two long levers fixed on an overhead
rocking shaft or centered on separate studs, and the levers are made to vibrate by
one or more revolving cranks or eccentrics. Means are provided for adjusting the
extent of vibration of the levers and the position of the brush on them to suit
different kinds of thread, and the brush may be a plain non-rotating one, or it may
be a roller brush mounted so as to be free to turn in the ends of the levers.
