CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS USED IN SIZING AND DRESSING YARN
Year: 1870

page_text: LETTERS PATENT to Colin Mather, of the Firm of Mather and Platt,
of Salford, in the County of Lancaster, Engineers, for the Invention
of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS USED IN SIZING
AND DRESSING YARN."
Sealed the 16th August 1870, and dated the 30th May 1870.
PROVISIONAL SPECIFICATION left by the said Colin Mather at the
Office of the Commissioners of Patents, with his Petition, on the
30th May 1870.
I, COLIN MATHER, of the Firm of Mather and Platt, of Salford, in
the County of Lancaster, Engineers, do hereby declare the nature of the
said Invention for "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS USED
IN SIZING AND DRESSING YARN," to be as follows:-
My Invention is applicable to the machines for sizing and dressing
$6
66
yarn known as tape legs" or slashers," and it consists in an improved
mode of drying the yarn after it has passed through the sizing rollers
and before it is wound on the warp beam. It has heretofore been
customary to agitate the air under the yarn by an open fan and to
pass the yarn over drying cylinders; now my Invention consists in
forcing highly heated compressed air against and between the yarn
as it passes from the sizing rollers to the warp beam.

page_text: In performing my Invention I cause the yarn to pass through narrow
slits in the sides of a chest in which is a perforated false bottom, and
these perforations can be opened or closed by sliding doors. The air
which has been highly heated and compressed in any ordinary manner,
is admitted below the false bottom, and passes through the perforations
above referred to. The upper part of the chest is in communication
with a ventilating flue to carry off the air and moisture discharged by
the yarn.
SPECIFICATION in pursuance of the conditions of the Lettors Patent,
filed by the said Colin Mather in the Great Seal Patent Office on
the 25th November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, COLIN
MATHER, of the Firm of Mather and Platt, of Salford, in the County
of Lancaster, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of May, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Colin Mather, Her special licence that I,
the said Colin Mather, my executors, administrators, and assigns, or
such others as I, the said Colin Mather, my executors, administrators,
and assigns, 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 "CERTAIN IMPROVEMENTS IN MACHINERY
OR APPARATUS USED IN SIZING AND DRESSING YARN," upon the condition
(amongst others) that I, the said Colin Mather, my executors or
administrators, 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.

page_text: NOW KNOW YE, that I, the said Colin Mather, 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 (that is to say) :-
"
It
My Invention is applicable to the machines for sizing and dressing
yarn known as "tape legs" or "slashers and other similar machines
in which the yarns forming a warp are sized and dressed simultaneously,
and it consists in an improved mode of drying the yarn after it has passed
through the sizing rollers and before it is wound on the warp beam.
has heretofore been customary to agitate the air under the yarn by an
open fan, and to pass the yarn over drying cylinders; now my Invention
consists in forcing highly heated compressed air against and between
the yarn as it passes from the sizing rollers to the warp beam.
And in order that my Invention may be fully understood and readily
carried into operation I will proceed to describe the accompanying Sheet
of Drawings, in which Fig. 1 is an elevation in section, and Fig. 2 a
plan of the principal parts of a machine for sizing and dressing yarn
constructed according to my Invention.
a, a, are the beams on which the yarn to be operated upon is supplied
to the machine; b, b, are guide rollers over which the yarn passes, and
between which the roller b¹ is suspended to take up the slack; c is the
trough containing the size; d is the immersing roller; and e and fare
the squeezing rollers in the size trough; these parts are made in the
usual manner. After the yarn has passed between the rollers e and fit
is taken into the chost g which contains the creels j and k, around which
the yarn is carried, as indicated by the arrows, and from the latter
of which it is guided through a narrow slit in the back plate of the
chest g.
While the yarn is passing through the chest g, it is dried
by highly heated compressed air which is forced into the chest 9, and
the air is heated and compressed in the following manner:-The fan m
is caused to revolve rapidly, and in so doing the air drawn into the
casing of the fan is forced through the tubes in the heating chamber n,
which is supplied with high-pressure steam from any ordinary steam
boiler, n being the supply pipe, and n² the off pipe for the water of
condensation, and as the steam surrounds the tubes through which the air
is forced, it is evident that the air is heated in passing through them,
and the compressed air so heated is then forced into the chest g. After
the air has penetrated through and between the sized yarn, passing

page_text: through the chest g, it is carried off by the ordinary ventilating flue g¹.
When the yarn has passed though the slit in the back plate of the chest g
it is taken under and over the rollers o and p, then through the ordinary
opening bars and wraiths or reeds, and then it is wound as usual on the
warp beam q. The gearing for driving the size roller and the warp
beam is made as usual.
From the foregoing description it will be seen that the ordinary drying
cylinders around which the wet yarn is taken in the machines heretofore
employed are dispensed with, and the size is distributed uniformly on
each individual yarn, because the current of heated air passing through
the chest g agitates the yarns and prevents them adhering together when
drying, whereas when the wet yarns come in contact with the heated
surface of the ordinary drying cylinder they are partially glued together
by the size, and must be separated afterwards by the wraiths or reeds,
thereby leaving rough edges which injure the healds of the loom, and are
otherwise objectionable.
I wish to remark that my improvements may be applied in lieu of or
in addition to the ordinary open fan and drying cylinders now used in
sizing and dressing machines.
Having thus stated the nature of my invention and described a
convenient mode of performing the same, I wish it to be understood
that I do not limit myself to the details given, as in some cases it may
be desirable to admit the heated air to the chest g, through a perforated
false bottom, and the arrangement of the parts may be otherwise
modified to suit the peculiar construction of the sizing and dressing
machine to which my improvements may be applied, I claim, the appli-
cation of heated compressed air for drying the yarn passing through
machines for sizing and dressing.
In witness whereof, I, the said Colin Mather, have hereto set
my hand and seal, this Twenty-first day of November One
thousand eight hundred and seventy.
