IMPROVED ARRANGEMENTS FOR DRESSING OR SIZEING WARPS."
Year: 1862

page_text: LETTERS PATENT to Alexander Twaddell, of Glasgow, in the County of
Lanark, North Britain, Manufacturer, for the Invention of "IMPROVED
ARRANGEMENTS FOR DRESSING OR SIZEING WARPS."
PROVISIONAL SPECIFICATION left by the said Alexander Twaddell at
the Office of the Commissioners of Patents, with his Petition, on the
13th November 1862.
I, ALEXANDER TWADDELL, of Glasgow, in the County of Lanark, North
Britain, Manufacturer, do hereby declare the nature of the said Invention
of "IMPROVED ARRANGEMENTS FOR DRESSING OR SIZEING WARPS," to be as follows,
that is to say:
This Invention relates to improved arrangements for dressing or sizeing
warps, and designed to admit of differently colored warps being simultaneously
dressed without the colors injuring each other, and in a more convenient and
satisfactory manner than hitherto.
The improved arrangements are applied to the entering or dressing end of
the well-known "tape" machine or warp-sizeing apparatus. One portion of
the warps drawn off one or more beams, as the case may be, after passing

page_text: between a pair of entering rollers descends in the usual way under and round a
roller immersed in the usual starch or size box, and then passes up and between
the first pair of squeezing rollers, and onwards between the second pair of
squeezing rollers or "finishers." The other portion of the warps, which it is
wished to keep clear from the color of the first portion, is made to pass from
the entering rollers in an upward direction to a separate starch or size box
In
mounted upon brackets directly over the ordinary starch or size box.
passing upwards to this separate box, this portion of the warps. is in a most
convenient position for being watched by the attendant, and it receives its
dressing either by passing between a pair of rollers, the lower one of which is
immersed in the starch or size, or by being made to descend round a roller
into the starch, and then through a pair of squeezing rollers. From this
separate starching or sizeing box the upper portion of the warps is made to
descend and combine with the lower portion of the warps, either before or
after they pass through the finishing squeezers. With these arrangements the
separated warps which are passed over the upper starch or size box are
subjected to the least possible strain and may be very light or few, which is of
great advantage for many kinds of fabrics. In the lower starch or size box
there may be a division between the two pairs of squeezing rollers for the
purpose either of entirely excluding starch or size. from the second pair of
rollers, or of applying to this pair a different, for example, a lighter starch
or size.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexander Twaddell in the Great Seal Patent Office on the
12th May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
TWADDELL, of Glasgow, in the County of Lanark, North Britain, Manufac-
turer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Alexander Twaddell, Her special licence that I, the said Alexander
Twaddell, my executors, administrators, and assigns, or such others as
I, the said Alexander Twaddell, my executors, administrators, and assigns,

page_text: should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVED ARRANGEMENTS FOR DRESSING OR SIZEING WARPS," upon the condition
(amongst others) that I, the said Alexander Twaddell, my executors or admi-
nistrators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters.
Patent.
.
NOW KNOW YE, that I, the said Alexander Twaddell, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement in writing, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon, that is to say :-
My said Invention relates to improved arrangements for dressing or
sizeing warps, such arrangements being designed to admit of differently
colored warps being simultaneously dressed without the colors injuring each
other, and in a more convenient and satisfactory manner than hitherto.
And in order that my said Invention, and the manner of performing the
'same may be properly understood, I have hereunto appended a, Sheet of
explanatory Drawings to be herein-after referred to and representing a modi-
fication of apparatus fitted with my improvements.
My improved arrangements are applied to the entering or dressing end of
the well-known "tape" machine or warp sizeing apparatus, and in the accom-
panying Drawing, as much of the machine is shown as appears necessary to
render the application of my Invention intelligible.
In the Drawing the apparatus is shown in longitudinal vertical section.
One portion A of the warps drawn off one or more beams B, as the case may
be, after passing through a reed C between a pair of entering rollers D, and
over a guide roller E, descends in the usual way under and round a roller F,
immersed in the usual box G containing starch or size, aud then passes up
and between the first pair of squeezing rollers H, and onwards between the
second pair of squeezing rollers or "finishers" I. The other portion J of the
warps, which it is wished to keep clear from the color of the first portion A,
and which may either be white or of a color different from the portion A is

page_text: drawn off one or more beams K, and being, by preference, first passed between
a pair of rollers L, passes on through the reed C, and between the entering
rollers D. From these rollers D, however, the portion J of the warps
proceeds in an upward direction to a separate starch or size box M mounted
upon brackets or standards N, bolted to the side frames P of the machine;
this upper box M being directly over the ordinary starch or size box G. In
passing upwards to this separate box M, this portion of the warps is (at J¹),
in a most convenient position for being watched by the attendant. It receives its
dressing either by passing between a pair of rollers Q, the lower one of which
is partly immersed in the starch or size, as shown in the Drawing, or by being
made to descend round a roller into the starch or size and then through
a pair of squeezing rollers. The warps J pass over guide rollers R, S,
at the corners of the box M, and on leaving the box are made to descend
as at J, and combine with the lower portion A, either before these pass
through the squeezing rollers or finishers I, as shown, or after they have
passed through the finishers, and before or after they have been acted upon
by the rotatory brush T, but always before or on passing upon the steam-
heated drying cylinder or can U. If wished, the upper warps J may be acted
upon by a separate rotatory brush. After the warps are combined they pass
onwards through the machine in the usual way.
With the described arrangements the separated warps J, which are passed
over the upper starch or size box M are subjected to the least possible strain,
and may consequently be very light or few, the practability of which is of
great advantage for many kinds of fabrics. In the lower starch or size box G
there may be a dividing partition V between the two pairs of squeezing rollers
H, I, for the purpose either of entirely excluding starch or size from the
second pair of rollers I, or of applying to this pair a different, for example, a
lighter starch or size.
It will be obvious that the same system may be carried still further, namely,
by arranging a third starch or size box above the box M with rollers for acting
on a third portion of the warps independently of the others.
Having thus particularly described my said Invention and the manner in
which the same is or may be performed, I have to state that I do not restrict
myself to the precise details herein described and delineated; but that what I
I believe to be novel and original and claim as the Invention secured to me by
the herein-before in part recited Letters Patent is, the arranging of machinery
for dressing or sizeing warps, so that temporarily separated portions of the
warps may be independently dressed or sized, and be combined with the rest

page_text: of the warps before or when passing upon the drying cylinder, substantially
as herein-before described.
In witness whereof, I, the said Alexander Twaddell, have hereunto set
my hand and seal, this Eleventh day of May, in the year of our
Lord One thousand eight hundred and sixty-three.
ALEXANDER TWADDELL. (L.S.)
