page_text: LETTERS PATENT to Samuel Tatton, of Leek, in the County of Stafford,
Silk Dyer, for the Invention of "IMPROVEMENTS IN PREPARING AND
TREATING SILK, AND IMPROVEMENTS IN DYEING SILK."
Sealed the 7th October 1859, and dated the 12th April 1859.
PROVISIONAL SPECIFICATION left by the said Samuel Tatton at the
Office of the Commissioners of Patents, with his Petition, on the 12th
April 1859.
I, SAMUEL TATTON, of Leek, in the County of Stafford, Silk Dyer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PREPARING AND TREATING SILK, AND IMPROVEMENTS IN DYEING SILK," to be as
follows:-
My Invention consists in preparing or treating raw silk, silk thread, sewing
silk, or silk twist (commonly called Barber's sewings or boot twist), so as to give
strength, weight, and elasticity thereto by submitting the silk to a bath of sugar
and gum, or other glutinous substance, mixed in proportions varying with the
nature of the silk and the effects to be produced thereon.
My Invention further consists in dyeing the said raw and other silk yellow
and gold colors, and all shades thereof, by submitting the silk to a bath con-
taining nitro-muriate or muriate of tin, or other solutions of tin or any of its
salts or compounds; also to a bath containing Persian or Turkey berries; also
to a bath containing Aleppo galls or shumac, or other substance or material-
containing tan or tanning matter; also to a bath containing sugar and gum or
other glutinous substance; also to a bath of nitric or nitro-muriatic acid; and
also to a bath of soda or other alkali.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
TATTON, of Leek, in the County of Stafford, Silk Dyer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of April, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Samuel Tatton, Her special licence that I, the said
Samuel Tatton, my executors, administrators, and assigns, or such others
as I, the said Samuel Tatton, 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 PREPARING AND TREATING SILK, AND IMPROVEMENTS IN DYEING
SILK," upon the condition (amongst others) that I, the said Samuel Tatton, 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.
NOW KNOW YE, that I, the said Samuel Tatton, 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 fol-
lowing statement thereof, that is to say :-
My Invention consists, firstly, in preparing or treating raw silk, silk thread,
sewing silk, and silk twist, commonly called Barber's sewings or boot twist,
before or after being dyed any color except black, and whether manufactured
into thread or twist, or not, by submitting the silk to a bath of sugar, or of
sugar and gum, or to a bath of any other suitable glutinous substance; or,
instead of the bath of sugar and gum, or other glutinous substance, I treat the
silk to a bath containing Aleppo galls, shumnac, or other substance containing
tan or tanning matter.
My Invention consists, secondly, in dyeing raw silk, silk thread, sewing silk,
and silk twist, commonly called Barber's sewings or boot twist, yellow and

page_text: gold colors, and all shades thereof by submitting the silk to the following
baths: First, to a bath containing anatto and soap; second, to a bath con-
taining muriate of tin, or other solutions of tin or salts of tin; and third, to a
bath containing Persian or Turkey berries. I sometimes substitute for the
muriate of tin bath a bath containing nitric acid or nitro-muriatic acid, and
then wash the silk in a solution of soda or other alkali.
The strength of all the baths or solutions, whether for preparing or for
dyeing the silk, must be proportioned according to the effect to be produced
and to the state of the silk under treatment.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, preparing or treating raw silk, silk thread, sewing silk, and silk twist,
by the means and in manner herein-before described.
And, second, dyeing raw silk and silk threads yellow and gold colors, by the
means and in manner herein-before described.
In witness whereof, I, the said Samuel Tatton, have hereunto set my
hand and seal, this Seventh day of October, One thousand eight
hundred and fifty-nine.
SAMUEL TATTON. (L.S.)
