page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GRATRIX, of Salford, in the County of Lancaster, Silk Dyer, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Fifth day of January, in the third year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
Williani Gratrix, my exors, adiiors, and assigns, His especial licence, full-
power, sole privilege and authority, that I, the said William Gratrix, my
exors, adiiors, and assigns, and such others as I, the said William Gratrix,
my exors, admiors, and assigns, should at any time agree with, and no others,
from time to time and at all tinies hereafter during the term of years therein
mentioned, should.and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of
an "AN IMPROVED METHOD OF IMPARTING TO VARIOUS WOVEN FABRICS, OR TO THE
YARNS OR THREADS OF WHICH THE SAME ARE INTENDED TO BE COMPOSED, THE COLOR
NECESSARY TO FORM THE REQUIRED PATTERNS THEREON;" in which said Letters
Patent there is contained a proviso, that I, the said William Gratrix, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, by an instrument in writing under
my band and seal, to be enrolled in His Majesty's High Court of Chancery
within six calendar months next immediately after the date of the said in
part recited Letters Patent, as by the said Letters Patent, reference being
thereunto bad, may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Gratrix, do hereby declare the nature of my Invention, and the
manner in which the same is to be performed, are particularly described and
ascertained in and by the following description thereof, that is to say :--
My Invention consists in "An Improved Method of Imparting to various
Woven Fabrics, or to the Yarns or Threads of which the same are intended to be
Composed, the Color necessary to Form the required Patterns thereon," which I
effect by cutting out the design or pattern as it is to be represented on a thin
sheet of tin, copper, brass, or such.other-metal,-or-mixture of-metals, as may
be prepared suitably for the purpose, but the metals I have found hitherto best
adapted to this use are copper or tin. The design or pattern may also be cut
out upon a sheet of tough paper rendered impermeable to colour by prepared
oil or varnishes, or upon squares of a fine close texture of silk, cotton, or other
fabrics previously rendered waterproof or impermeable to colour. When the
cutting out of the design or pattern upon the metallic or other sheet is
completed, the same is extended upon a marginal frame, so as to leave the
interstices, or spaces which form the pattern, free and uncovered on both sides,
then applying the flat side to the woven fabric, yarn, or thread evenly extended
upon a plane of wood or stone for the purpose, the upper side is rubbed over
with the colour intended to be imparted to the same, until the fabric, yarn, or
thread is thoroughly or sufficiently impregnated. This I effect with a brush
about three inches square, presenting a base as fully studded with bristles as
possible, or with a rubber of woollen cloth or other proper material. The
colour may also be imparted by covering the interstices which form the pattern
with a piece of any kind of even material porous enough to imbibe a proper
quantity of coloring matter, and then pressed through upon the fabric, yarn, or
thread, either by means of a press, or by striking a few blows on a flat block
of wood planed true and placed thereon so as to cover the extent of the
pattern. The mode of framing the sheets, adjusting the pattern, and applying
the colour, admits of much and great variation, but the privilege to which I
lay claim is the imparting of colour to woven fabrics in the piece, but more
particularly to the yarns or threads of which the same may be composed,
through the medium of interstices or spaces cut out of sheets of tin, copper,
brass, or any other metals or alloys of metal, or out of paper render imper-
meable to colour, or out of squares of a fine close texture of silk, cotton, or
other material made waterproof or rendered impermeable to colour, in such
design, figure, or form as I may be desirous of representing or producing upon
the same; and such my Invention being, to the best of my knowledge and belief,
eutirely new, and never before used within. that part of Elis said Majesty's

page_text: United Kingdom of Great Britain and Ireland called England, His said.
Dominion of Wales, or Town of Berwick-upon-Tweed, I do hereby declare
this to be my Specification of the same, and that I do verily believe this my
said Specification doth comply in all respects fully and without reserve or
disguise with the proviso in the said herein-before in part recited Letters
Patent contained; wherefore I do hereby claim to maintain exclusive right and
privilege to my said Invention.
In witness whereof, I, the said William Gratrix, have hereunto set my
hand and seal, the Twenty-sixth day of June, in the year our Lord
One thousand eight hundred and thirty-three.
