Year: 1860

page_text: LETTERS PATENT to John Wilson Hadwen, of Kebroyd Mills, in the
Parish of Halifax and West Riding of the County of York, Cotton
Spinner, for the Invention of "IMPROVEMENTS IN THE TREATMENT OF SILK
WASTE, WASTE SILK OR SILKEN FIBRE, AND IN THE MANUFACTURE OF YARNS
AND TISSUES FROM THE SAME, WHETHER ALONE OR IN ADMIXTURE WITH OTHER
MATERIALS."
Sealed the 22nd May 1861, and dated the 26th November 1860.
PROVISIONAL SPECIFICATION left by the said John Wilson Hadwen
at the Office of the Commissioners of Patents, with his Petition,
on the 26th November 1860.
I, JOHN WILSON HADWEN, of Kebroyd Mills, in the Parish of Halifax
and West Riding of the County of York, Cotton Spinner, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE TREATMENT OF
SILK WASTE, WASTE SILK OR SILKEN FIBRE, AND IN THE MANUFACTURE OF YARNS
AND TISSUES PROM THE SAME, WHETHER ALONE OR IN ADMIXTURE WITH OTHER
MATERIALS," to be as follows:-
My improved modes of treatment and manufacture consist in the admixture
at some stage of the processes preparatory to that of spinning (such as
scribbling, carding, or drawing) of duly proportioned quantities of silk waste,
waste silk, or other silken fibre of two or more different colors in order to
produce by the more or less intimate blending of such colors mixed hues or
compound tints of an ornamental character in the yarn or fabrics to be made,

page_text: the tints obtained being either regular and uniform, or delicately clouded,
mottled, or parti-colored, according to the management of the process.
The Invention includes the application of the like treatment to all or any
mixture or mixtures of silk waste or waste silk with other materials, and also
the reduplication of the process or treatment, by blending or intermingling
materials of mixed hues or colors already obtained by the improved mode.
It also embraces, as a new manufacture, a novel description of cloth for
making umbrellas and parasols, the peculiarity of which consists in or arises
from its being composed wholly or partially of yarns made as above men-
tioned, or of such yarns doubled with some other thread.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Wilson Hadwen in the Great Seal Patent Office on
the 25th May 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILSON HADWEN, of Kebroyd Mills, in the Parish of Halifax, and West
Riding of the County of York, Cotton Spinner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
ent, bearing date the Twenty-sixth day of November, in the year of our
Loru thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Wilson Hadwen, Her special licence that I, the said John Wilson
Hadwen, my executors, administrators, and assigns, or such others as I, the
said John Wilson Hadwen, 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 THE TREATMENT OF SILK WASTE, WASTE SILK OR SILKEN
FIBRE, AND IN THE MANUFACTURE OF YARNS AND TISSUES FROM THE SAME, WHETHER
ALONE OR IN ADMIXTURE WITH OTHER MATERIALS," upon the condition (amongst
others) that I, the said John Wilson Hadwen, 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 John Wilson Hadwen, 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):
My Invention consists of mixing in one or more of the processes for
preparing fibrous materials to be spun (such as the scribbling, carding, or
drawing processes) of silk waste, waste silk, or other silken fibre of different
colors and suitable proportions of each color to produce mixed hues or com-
pound tints in yarn or fabrics of an ornamental description; the tints or
hues thus obtained being either regular and uniform, delicately clouded,
mottled, or parti-colored according to the relative proportions of the various
colors mixed together.
I also mix or blend silk waste or waste silk with other materials in the
manufacture of yarn or fabrics at any of the aforesaid processes of preparing
fibrous materials to be spun, or I mix them at one of the said processes, and
repeat it at another, as will be found desirable in practice.
By the aforesaid process I produce a novel description of cloth for covering
umbrellas and parasols, the peculiarity of which consists in its being made
wholly or partially of yarns made as herein-before described, or of the said
yarns doubled with some other kind of yarn or material.
Having thus described the nature of my said Invention, and the manner in
which the same is to be performed, I desire it to be distinctly understood that
I claim as my Invention, and which to the best of my knowledge and belief,
has not been hitherto used within the realm, the mixing or blending of silk
waste, waste silk, or other silken fibre of different colors and suitable pro-
portions in one or more of the preparatory processes for spinning, and also
of mixing the same with other suitable materials.
In witness whereof, I, the said John Wilson Hadwen, have hereunto set
my hand and seal, this Twenty-first day of May, in the year of our
Lord One thousand eight hundred and sixty-one.
Signed, sealed, and delivered by the
within-named John Wilson Hadwen,
in the presence of
J. WILSON HADWEN. (L.S.)
J. LOVEL HADWEN.
