PROVISIONAL SPECIFICATION.
Improvements in Polishing Yarn and Apparatus therefor.
I, EDWARD CASPER, of No. 21, Colville Terrace, Bayswater, in the county of
Middlesex, Gentleman, do hereby declaro the nature of this invention (a communication
from abroad by Jules Papleux, of Rue D'Enghien, Paris, in the republic of France,
Weaver,) to be as follows:-
This invention relates to an improved apparatus whereby the polishing of yarn is
effected without the yarn being flattened.
This improved apparatus is constructed of two, four, six, or other suitable number
of hollow rollers or cylinders adapted to be heated by steam and mounted in a frame
and revolved in any suitable manner. But the essential feature of this invention
consists in providing these rollers or cylinders around their circumferences with semi-
circular grooves placed at short distances apart and through which grooves the yarn
to be polished is drawn the polishing being thus effected without in any way flattening
the yarn under treatment.
It will be obvious that the yarn to be polished is drawn through a size-box or other
| bath containing dressing as usual.

Improvements in Polishing Yarn and Apparatus therefor.
I, EDWARD CASPER, of No. 21, Colville Terrace, Bayswater, in the County of
Middlesex, Gentleman, do hereby declare the nature of this invention (a communication
from abroad by Jules Papleux, of Rue D'Enghien, Paris, in the Republic of France,
Weaver) and in what manner the same is to he performed to be particularly described
and ascertained in and by the following statement :-
This invention relates to an improved apparatus whereby the polishing of yarn is
effected without the yarn being flattened.
This improved apparatus is constructed of two, four, six, or other suitable number
of hollow rollers or cylinders adapted to be heated by steam and mounted in a frame
and revolved in any suitable manner. But the essential feature of this invention
consists in providing these rollers or cylinders around their circumferences with semi-
circular grooves placed at short distances apart and through which grooves the yarn
to be polished is drawn the polishing being thus effected without in any way flattening
the yarn under treatment.
It will be obvious that the yarn to be polished is drawn through a size-box or other
bath containing dressing as usual.
In the accompanying drawing
Figure 1 is a front elevation, and
Figure 2 is a side elevation of an apparatus for polishing yarn constructed according
to this invention.
Figure 3 is a longitudinal section drawn to a larger scale of a portion of one of the
hollow rollers or cylinders.
Similar letters in all the figures indicate similar parts.
a, a are the hollow rollers or cylinders eight of which are shown in figures 1 and 2
of the drawing mounted in bearings b, b on a frame c. This number can however be
varied as required.
.
d, d are the semi-circular grooves with which the rollers or cylinders a, a are provided
around their circumferences.
e, e are chain wheels, by means of which and a chain (not shown in the drawing),
driven from any suitable motor, the rollers are rotated.
fis a vertical tube having horizontal branch tubes g, g through which steam entering
the vertical tube at h is forced through the hollow spindles i, i and thence into the
interior of the rollers or cylinders a, a in order to heat them.
j and k, kare tubes similar to those shown at fand 9, 9 respectively but serving to
conduct the steam from the rollers or cylinders to the outlet 1.
m, m are stuffing boxes in which the ends of the roller spindles i, i are mounted so
as to prevent any escape of steam at this part.
Figure 2 shows the direction of travel of the yarn over the several rollers a, the
said yarn being indicated by the letter n. It is drawn through the semi-circular

page_text: grooves d, d and this drawing through the grooves of the rollers a while steam is
cansed to pass through the rollers, restores to the yarn the polish and softness which
it may have lost while being dyed or while being bleached and the yarn will com-
pletely retain its roundness which has not hitherto been the case with existing yarn
polishing apparatus.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. Providing the rollers or cylinders of yarn polishing apparatus with semi-
circular grooves around their circumferences, substantially as and for the purpose
set forth.
2. The improved apparatus for polishing yarn hereinbefore described and illustrated
in the accompanying drawing.
