Year: 1825

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DAVID
OLIVER RICHARDSON, of Leeds, in the County of York, Kerseymere and Cloth
Printer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-sixth day of July, in the sixth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
David Oliver 'Richardson, and also to WILLIAM HIRST, of Leeds, aforesaid,
Manufacturer, His especial licence that we, the said David Oliver Richardson
and William Hirst, our exors, admors, and assigns, or such others as we, the
said David Oliver Richardson and William Hirst, our exors, adñiors, or
assigns, should at any time agree with, and no others, from time to time and
at all times during the term of years therein expressed, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, our Invention of "CERTAIN IMPROVEMENTS IN THE
PROCESS OF PRINTING OR DYEING WOOLLEN AND OTHER FABRICKS;" in which said
Letters Patent is contained a proviso obliging us, or one of us, the said
David Oliver Richardson and William Hirst, by an instrument in writing
under our or one of our hands and seals, particularly to describe and ascertain
the nature of our said Invention, and in what manner the same is to be per
formed, and to cause the same to be enrolled in His said Majesty's High
Court of Chancery within six calendar months next and immediately after tho
date of the said recited Letters Patent, as in and by the same, referencj
being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
David Oliver Richardson, do hereby declare the nature of our said Invention
to consist in covering part of woollen or worsted fabrics with a composition
which resists the effects of the dyeing materials, and of the process of dyeing,
during the operation of dyeing those parts of the same fabricks which are not
so covered as aforesaid. And in further compliance with the said proviso, I,
the said David Oliver Richardson, do hereby describe the manner in which
our said Invention is to be performed, by the following description thereof
(that is to say):
In order to make our said composition we mix five stone of flour with
about four gallons of water, and stir them together till they attain the
consistency of treacle. This mixture we allow to stand for two or three days;
at the end of which time we add the yolks and whites of forty raw eggs to it,
and mix the whole well together. As soon as this is done the mixture is
ready for use, and is to be laid on with a brush or by blocks, or in any other
convenient modes, over such parts of the fabric as are not intended to be
operated upon by the dye. When the parts have been so covered as aforesaid,
if a little powdered glass or powdered shells, or even fine sand, be sifted through
a sieve into the composition, it will tend to set and bind it the more firmly,
though this last operation is not absolutely necessary. When the composition
on the fabric has become set the fabric may be put into the dye kettle and
boiled for any necessary length of time; and it will be found that all those
parts which we covered with the composition will not have been the least
effected by the dye. When the dyeing is completed the composition may be
scraped off without difficulty, and without injury to the fabric. For the
purpose of further elucidating our Invention I will suppose a lady's square
shawl is the object to be operated upon, and that it is required to dye one side
of it a plain blue, without any border, and the other side a rose-coloured
ground, leaving a white border to be afterwards printed with a chintz pattern.
We should stretch the shawl upon a square stretching frame, and cover the
side that was to be blue, and the white border of the other side, with the com-
position, leaving only the ground that was to be rose colored exposed to the
action of the dye. We then put the fabric on the frame into a cradle made to
support it edgeways, and let the cradle frame and all down into a square dye
kettle of rose-colored dye. When it is removed from the dye kettle it will be
found that the ground only of one side has been affected by the dye. That
ground will, of course, be rose colored. The whole of the composition will
then be removed from the side that is intended to be blue, and the rose-colored
part is covered with composition. When this comes out of a kettle of blue

page_text: dye, and all the composition from both sides removed, it will be found that the
object desired has been obtained; one side will be a plain blue without
any border, and the other rose be a rose-colored ground with a white border.
This white border may afterwards be printed with any chintz pattern in the
ordinary way.
Now, whereas we claim as our Invention the covering of parts of woollen
and worsted fabrics which are to be dyed or printed with a composition
which resists the action of the dye when the fabric is in the dye kettle, as
herein-before described, as also the application of the particular composition
herein-before also described to that particular purpose, and such our
Invention being, to the best of our knowledge and belief, entirely new,
and never before used within that part of His said Majesty's 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 our Specification of our said Invention, and that I do verily believe
this our said Specification doth comply in all respects, fully and without
reserve or disguise, with the proviso in our said herein-before in part recited
Letters Patent contained; wherefore we do hereby claim to maintain exclusive
right and privilege to our said Invention.
In witness whereof, I, David Oliver Richardson, have hereunto set my
hand and seal, this Twelfth day of January, in the year of our Lord
One thousand,eight hundred and twenty-six.
DAVID OLIVER (L.S.) RICHARDSON.
AND BE IT REMEMBERED, that on the Twelfth day of January, in the
year of our Lord 1826, the aforesaid David Oliver Richardson came before
our said Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
Inrolled the Fourteenth day of January, in the year of our Lord One
thousand eight hundred and twenty-six.
