page_text: LETTERS PATENT to Edward Schischkar, of the firm of James
Akroyd and Son, of Halifax, in the County of York, Manufac-
turers, for the Invention of "IMPROVEMENTS IN DYEING AND
COLORING YARNS AND TEXTILE FABRICS,"
Sealed the 7th May 1858, and dated the 18th December 1852.
PROVISIONAL SPECIFICATION left by the said Edward Schischikar
at the Office of the Commissioners of Patents, with his l'e-
tition, on the 18th December 1852.
I, EDWARD SCHISCHкAR, of the firm of James Akroyd and Son,
of Halifax, in the County of York, Manufacturers, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN
DYEING AND COLORING YARNS AND TEXTILE FABRICS" to be as
follows:.
I introduce into the dye bath, whatever may be the dye used, a
certain quantity of sulphate of copper.
I remove the goods into a close vessel, and there submit them to
the action of steam or hot air, whereby the metallic mordant will
rise on the surface of the yarns or fabrics, and impart to them a
bright silky appearance.

TO ALL TO WHOM THESE - PRESENTS SHALL COME, I,
EDWARD SCHISCHKAR, of the firm of James Akroyd and Son, of
Halifax, in the County of York, Manufacturers, send greeting.
WHEREAS Her Most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth of December, in the year
of our Lord One thousand eight hundred and fifty-two, in the Six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Edward Schischkar, Her special
licence that I, the said Edward Schischkar, my executors, adminis-
trators, and assigns, or such others as I, the said Edward Schischkar,
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 "IMPROVEMENTS IN DYEING AND COLORING YARNS AND
TEXTILE FABRICS," upon the condition (amongst others) that I, the
said Edward Schischkar, 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.
NOW KNOW YE, that I, the said Edward Schischkar, do hereby
declare the nature of my said Invention, and in what manner the
saine is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say):
My Invention consists of the following process or mode of
dyeing and colouring yarns and textile fabrics of all descriptions,
whereby I am enabled to impart to the materials treated a bright
metallic lustry appearance.

page_text: I introduce into the dye bath, or into the colours used for printing
the yarns or textile fabrics, a quantity (more or less, according to
the effect to be produced) of sulphate of copper; and I submit the
articles so dyed or coloured to the action of steam, or steam im-
pregnated with nitro-muriate of tin, in an apparatus or box her-
metically closed, so as to prevent the access of air during the
steaming operation; which I continue for from about one to two
hours, or until the articles exhibit a metallic lustre. The sub-
jecting the articles to the action of steam impregnated with nitro-
muriate of tin may be effected in various ways; for example, by
placing the goods or yarns in a closed box, over a blanket or flannel
soaked in a solution of the nitro-muriate of tin, and then passing
steam over their surfaces; or by saturating the articles themselves
with a solution of the salt, and then submitting them to the action of
steam in a closed box or apparatus; or other modes of proceeding
may be adopted. The effect produced on the goods or yarns may
be varied by varying the quantity of sulphate of copper introduced
into the dye liquor or colour used for printing or otherwise
marking the articles.
And having now described the nature of my said Invention, and
in what manner the same is to be performed, I declare that what I
claim is, the chemical process herein-before described, by which a
brilliant metallic lustre is imparted to the yarns or textile fabrics
submitted to the same.
In witness whereof, I, the said Edward Schischkar, have here-
unto set my hand and seal, the Fifteenth day of June, One
thousand eight hundred and fifty-three.
Witness,
JOHN BANCROFT.
