GRIMSHAW, of Strines Hall, in the County of Derby, Callico Printer, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by.
His Letters Patent under the Great Seal of Great Britain; bearing date at
Westminster, the Seventeenth day of February, in the thirty-sixth year of
His reign, give and grant unto me, the said John Grimshaw, my executors,
administrators, and assigns, His especial licence,.full power, .sole privilege
and authority, that I, the said John Grimshaw, my executors; administrators,
and assigns, and every of them, during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within' that part of
the Kingdom of Great Britain called England, the Dominion of Wales, and
Town of Berwick-upon-Tweed, my Invention or Discovery of "CERTAIN
VEGETABLE SUBSTANCES, IN PARTICULAR STATES OF PREPARATION, TO BE USED IN
CLEARING OR BLEACHING, OR ASSISTING TO CLEAR OR BLEACH, PRINTED, PAINTED,
STAINED, OR DYED CLOTHS, OR OTHER MATERIALS, CONSISTING OF OR MANUFACTURED
FROM LINEN, COTTON, HEMP, SILK, OR WOOL, OR ANY TWO OR MORE OF THEM;
AND OTHER PRINTED, PAINTED, STAINED, OR DYED GOODS, MANUFACTURED OR

page_text: PRODUCED FROM ANIMAL OR VEGETABLE MATERIALS, OR BOTH;" in which Letters
Patent there is contained a proviso obliging me, the said John Grimshaw,
'by an instrument in writing under my hand and seal, to describe and ascertain
the nature of any said Invention or Discovery, and in what mauuer the same
is to be performed, and to cause the same to be inrolled in His Majesty's
High Court of Chancery within one calendar month next after the date of
the said recited Letters Patent, as in and by the same, relation being there-
unto hail, may more fully, and at large appear.
NOW KNOW YE, that in pursuance of and compliance with the said
recited proviso, I, the said John Grimshaw, do hereby declare that the
nature of my said Invention or Discovery is as follows:-
The Vegetable Substances, in particular States of Preparation, to be used
in Clearing or Bleaching, or assisting to Clear or Bleach, Printed, Painted,
Stained, or Dyed Cloths, or other Materials, consisting of or manufactured from
Linnen, Cotton, Hemp, Silk, or Wool, or any Two or more of them; and other
Printed, Painted, Stained, or Dyed Goods, manufactured or produced from
Animal or Vegetable Materials, or Both, consist of the grains either of barley,
wheat, oats, rye, or any other corn, which remain after such barley, wheat, oats,
rye, or other corn have been made into malt, or brought into a sweet state, and
either brewed for the purpose of making ale, beer, or other malt liquor, or used
for the purpose of distillation; such grains in all cases to be brought into a
sour state, either by keeping the same without mixture until they become sour,
or by mixing the same either with sour beer, or with alegar or vinegar,
or with cream of tartar, or with any other acid, in order to render the same
Sour.
Manner of using the Sour Grains.-The manner of using such sour grains
is, by putting three or four bushels, or a greater or less quantity of the same,
either into a copper or other pan or vessel containing either two hundred
gallons, or more or less of water or other liquid, and either in a boiling or hot
state, and putting four or more or fewer picces of such printed, painted,
stained, or dyed cloths, or other materials or goods, into such mixture, and
continuing the same in such mixture, either for five or ten minutes, or a
greater or less length of time. This operation may be performed in a copper
pau, exactly similar to those which are used by callico printers, for the
purpose of clearing their printed callicoes, cottons, and linens with bran, and
it renders the use of bran unnecessary. The operation may be greatly expe
dited by working the pieces quickly out of and into the mixture by means of a
wince or reel pluced across the top of the pan or vessel above the mixture,

page_text: over which wince or reel each of the pieces may be made to pass. The wince
or reel may be turned quickly round, either by the hand of a man or any other
power.
The manner in which I generally exercise my Invention or Discovery is
as follows:-I take any quantity of common brewhouse grains, such as
remain after ale or beer has been brewed in the common way from barley
malt, and put them close together into a vessel, tub, cask, or cistern, for the
purpose of turning them sour. In hot weather they will become sour in about
six days; in cold weather they will become sour in about eight days. When
the grains are sour, I put two, three, or four Winchester bushels of them into
a common sized callico printer's dying copper pan, nearly full of boiling
water. Into this mixture I put four pieces containing about twenty-one or
twenty-eight yards each in length of printed callicoes, cottons, or linens, and
work them quickly out of and into the mixture by turning them over a wince
or reel, as before described, placed over and across the pan. I continue this
operation from five to ten minutes, during which time I let the mixture gently
boil; I then take out the pieces and wash them immediately either in hot
water or cold water, and afterwards heat them in the same manner, as is
usually done with printed goods by callico printers, when such printed goods
have been cleared with bran. After I have used this mixture for clearing
twelve or sixteen pieces, I put one additional bushel of such sour grains as last
mentioned into the pan, and fill the pan up with additional water; when
it boils, I repeat the operation with other printed callicoes, cottons, and linens,
as before.
In witness whereof, I, the said John Grimshaw, have hereunto set my
hand and seal, the Ninth day of March, in the thirty-sixth year of
the reign of our Sovereign Lord George the Third, by the grace
of God, of Great Britain, France, and Ireland King, Defender of
the Faith, and so forth, and in the year of our Lord One thousand
seven hundred and ninety-six.

page_text: AND BE IT REMEMBERED, that on the said Ninth day of March, in
the year above written, the aforesaid John Grimshaw came before our Lord
the King in His Chancery, and acknowledged the Specification aforesaid, and
all and every thing therein contained, in form above written. And also the
Specification aforesaid was staniped according to the tenor of the Statute in
that case made and provided.
