LLOYD, of Manchester, in the County of Lancaster, Pattern Designer, and

WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-

did, for Herself, Her heirs and successors, give and grant unto us, the said
Nathaniel Lloyd and Henry Rowbotham, Her especial license, full power, sole
privilege and authority, that we, the said Nathaniel Lloyd and Henry
Rowbotham, our executors, administrators, and assigns, or such others as we,
the said Nathaniel Lloyd and Henry Rowbotham, our executors, administrators,
and assigns, should at any agree with, and no other, 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, and Wales, and the
Town of Berwick-upon-Tweed, our Invention of "CERTAIN IMPROVELIENTS IN
THICKENING AND PREPARING COLOURS FOR PRINTING CALICOES AND OTHER SUB-
STANCE3;" in which said Letters Patent is contained a proviso, that we, the
said Nathaniel Lloyd and Henry Rowbotham, shall cause a particular descrip-
tion of the nature of our said Invention, and in what manner the same is to
be performed, to be enrolled in Her Majesty's High Court of Chancery within
six calendar months next and immediately after the dato of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso," we, the said
Nathaniel Lloyd and Henry Rowbotham, do hereby declare, that the nature

page_text: of the same Invention, and the manner in which the same is to. be, is
particularly described and ascertained in and by the following explanation
thereof:-
Our Improvements in thickening and preparing colours for printing calicoes
and other substances consist in the substitution or employment of a certain
well-known article of commerce in place of the ordinary gums used for such
purposes. The article we use for thickening and preparing colours for printing
is the well-known brown sago of commerce, calcined from the granulated or
seed state in which it is usually imported. Sago reduced to flour and whitened
by the ordinary means may be also employed for the same purposes, but we
much prefer the plain brown.sago just as imported, calcined at once from the
granulated state, which saves the expense and process of pulverizing and
whitening, and the sago will also be found in practice to be much more
gelatinous than when in the flour state. The calcined brown sago merely
requires-to-be-mixed with water and brought up to two hundred or two
hundred and twelve Fahrenheit, when it is fit for use.
The above-described substitution or use of sago calcined from the granulated
state or employed in any other form for the purposes of thickening and pre-
paring colours for printing, in place of the gums now commonly used, we claim
as our Invention.
In witness whereof, we, the said Nathaniel Lloyd and Henry Rowbotham,
have hereunto set our hands and seals, this Sixth day of July, One
thousand eight hundred and forty-one.
Extraordinary in Chancery.,
HENRY
(L.S.) ROWBOTHAM.
