CERTAIN IM- PROVEMENTS IN 'GASSING' YARN AND TEXTILE FABRICS, AND IN THE APPA- RATUS CONNECTED THEREWITH
Year: 1857

page_text: LETTERS PATENT to James Mallison, junior, of Bolton-le-Moors, in the
County of Lancaster, Yarn Agent, for the Invention of "CERTAIN IM-
PROVEMENTS IN 'GASSING' YARN AND TEXTILE FABRICS, AND IN THE APPA-
RATUS CONNECTED THEREWITH."
Sealed the 30th April 1858, and dated the 3rd November 1857.
PROVISIONAL SPECIFICATION left by the said James Mallison, at the
Office of the Commissioners of Patents, with his Petition, on the
3rd November 1857.
I, JAMES MALLISON, junior, of Bolton-le-Moors, in the County of Lancaster,
Yarn Agent, do hereby declare the nature of my said Invention for "CERTAIN
IMPROVEMENTS IN 'GASSING' YARN AND TEXTILE FABRICS, AND IN THE APPARATUS
CONNECTED THEREWITH," to be as follows:--
My Invention is designed for the purpose of "gassing" or singeing yarns or
fabrics without subjecting them to the discoloration usually consequent upon
passing them through a flame or jet of gas evolving smoke unconsumed.
The apparatus for effecting this object consists in a metallic, conical, pyramidal,
or other suitably shaped burner or guide for the flame, the lower end of which
being broad and open, and the upper extremity terminating in a narrow open

page_text: slit, this guide or burner is to be placed and suitably secured upon the pipes
or burners usually employed in such machines, and the gas turned on to such
a height as to allow a small jet of blue light or flame to project a short
distance above the top of the narrow slit; through this flame the yarn or
fabric is to be passed, after which operation it will be found that no discolora-
tion will have taken place, as the admixture of air with the gas effected
within the metallic guide causes the proper consumption of gas and smoke
arising therefrom, thus causing the flame employed to "gas" or singe the
yarn or fabric to be smokeless and void of all discoloring properties.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Mallison, in the Great Seal Patent Office on the
3rd May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MALLISON, junior, of Bolton-le-Moors, in the County of Lancaster, Yarn
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of November, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said James Mallison, junior, Her especial license that I, the said James
Mallison, junior, my executors, administrators, and assigns, or such others
as I, the said James Mallison, junior, 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 Inven-
tion for "CERTAIN IMPROVEMENTS IN 'GASSING' YARN AND TEXTILE FABRICS, AND
IN APPARATUS CONNECTED THEREWITH," upon the condition, amongst others, that
I, the said James Mallison, junior, by an instrument in writing under my
hand and seal, 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 James Mallison, junior, do hereby
déclare 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 and accompanying. Drawings (that is to say):-
My Invention is designed for the purpose of "gassing" or singeing yarns
or fabrics, without subjecting them to the discoloration usually consequent
upon passing them through a flame or jet of gas evolving smoke unconsumed.
The apparatus for effecting this object consists in a metallic, conical, pyramidal,
or other suitably-shaped burner or guide for the flame, the lower end of which
being broad and open, and the upper extremity terminating in a narrow open
slit, this guide or burner is to be placed and suitably secured upon the pipes
or burners usually employed in such machines, and the gas turned on to such
a height as to allow a small jet of light or blue flame to project a short
distance above the top of the narrow slit; through this flame the yarn or
fabric is to be passed, after which operation it will be found that no
discoloration will have taken place, as the admixture of air with gas effected
within the metallic guide causes the proper consumption of gas and smoke
arising therefrom, thus causing the flame employed to "gas" or singe the yarn
or fabric to be suckeless and void of all discoloring properties.
In order that the Invention may be better understood and explained in
detail, I have hereunto attached a Sheet of Drawing, made upon about full
size, and having similar letters of reference marked upon corresponding parts
of the apparatus.
Fig. 1 is a sectional view of the guide, shewing the burner or tube upon
which it is supported; Fig. 2 is a side view of the same; and Fig. 3 is a
plan view, shewing the direction of the passage of the threads across the
narrow slit and through the flame, as indicated by the red lines.
In Figs. 1, 2, 3, a, a, are the tubes or burners supplying the gas to the
conically-formed guide or burner b, which will be seen is widely open to the
atmosphere at its lower end or base, and terminates in a narrow slit at its
upper end. The guide or burner may be made of any form which may be
found most effectual in causing the admixture of the air with the gas before
combustion, so that the smoke arising therefrom may be consumed instead of
passing off with the flame, and causing the discoloration of the yarn or fabric
passing through it for the purpose of being "gassed" or singed.
Having now described the nature of my said Invention, together with the
method of performing the same, I would remark, in conclusion, that I
claim,--

page_text: First, the admixture of atmospheric air with the gas, as applied to the
gassing or singeing of yarns or fabrics, whereby discoloration during such
process is avoided.
And, secondly, the novel description of apparatus for applying or effecting
the said improvement, as herein-before described, set forth, and fully exhibited
in the Drawings attached, or any modification thereof, being substantially the
same.
In witness whereof, I, the said James Mallison, have hereunto set my
hand and seal, this First day of May, in the year of our Lord One
thousand eight hundred and fifty-eight.
JAMES MALLISON, JUNR. (L.S.)
