page_text: LETTERS PATENT to John Erskine, of Glasgow, in the County of Lanark,.
North Britain, Merchant, for the Invention of "THE APPLICATION OF A.
NEW MATERIAL OR MIXTURE FOR DRESSING OR. SIZEING TEXTILE FABRICS OR.
MATERIALS."
Sealed the 2nd May 1856, and dated the 10th January, 1856.
PROVISIONAL SPECIFICATION left by the said John Erskine at the
Office of the Commissioners of Patents, with his Petition, on the 10th
January 1856.
I, JOHN ERSKINE, of Glasgow, in the County of Lanark, North Britain,
Merchant, do hereby declare the nature of the said Invention for "THE"
APPLICATION OF A NEW MATERIAL OR MIXTURE FOR DRESSING OR SIZEING TEXTILE
FABRICS OR MATERIALS" to be as follows, that is to say :-
This Invention relates to the application and use, in dressing or sizeing
textile fabrics or materials, of a new dressing material or sizecing mixture.
This sizeing material is composed by mixing together potato flour and wheaten
flour, or potato flour and rice flour. The particular proportions of the dif-
ferent kinds of flour may be varied in different cases, according to the require-
iments or peculiarities of the particular class of goods to which the dressing
or sizeing is to be applied. By the use of either of these sizeing mixtures
the required dressing effect is produced at a more economical cost than by
the means hitherto adopted.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ERSKINE, of Glasgow, in the County of Lanark, North Britain, Merchant,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of January, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Iler
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Erskine, Her special license that I, the said John Erskine, my
exccutors, administrators, and assigns, or such others as I, the said John
Erskine, my executors, administrators, or 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 vond, within the United Kingdom of Great Britain and Ireland, tho
Channel Islands, and Isle of Man, an Invention for "THE APPLICATION
OF A NEW MATERIAL OR MIXTURE FOR DRESSING OR SIZEING TEXTILE FABRICS
AND MATERIALS," upon the condition (amongst others) that I, the said John
Erskine, by an instrument in writing under my hand and seal, 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.
NOW KNOW YE, that I, the said John Erskine, 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 stato-
ment in writing, that is to say:-
My said Invention relates to the application and use, in dressing or sizeing
textile fabrics or materials, of a new dressing material or sizeing mixture.
This sizcing material is composed by mixing together potato flour and wheaten
Hour, or potato flour and rice flour. The proportions which I use or recom-
mend are half potato flour and half wheaten or rice flour; but I do not bind
myself to these proportions, as they may be varied in different cases, according
to the requirements or peculiarities of the particular class of goods to which
the dressing or sizeing material is to be applied. In preparing the mixture
for the dresser or sizer, it is done in the usual way, by using a certain pro-
portion of the material to a certain quantity of water, which is then boiled.

page_text: I prefer to use one pound weight of the mixture to one imperial gallon of
water, and to boil the same for about twonty minutes; but I have found this
mixture to improve by being well boiled, and therefore consumers cannot go
wrong although they boil it during as much as three hours. After boiling,
the mixture is run into tubs, such tubs being by preference of a shallow kind.
This mixture can be used either entirely by itself, or in any proportion with
other sizcing materials, such, for instance, as sago flour, and by means of it the
required dressing effect is produced at a more economical cost than by the
means hitherto adopted.
Having now described and particularly ascertained the nature of my said
Invention, and the manner in which the same is or may be used or carried
into effect, I may observe, in conclusion, that I do not confine or restrict
myself to the precise details or arrangements which I have had occasion to
describe or refer to, as many variations may be made therefrom without
deviating from the principles or main features of my Invention; but what
I consider to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent, is, the application
and use, in the sizeing or dressing of textile fabrics and materials, of a
mixture composed of potato flour and wheaten flour, or of potato flour and
rice flour, such mixture being used either alone or in combination with other
sizcing materials, as hercin-before described.
In witness whereof, I, tho said John Erskine, have hereunto set my
hand and seal, this Eighth day of July, One thousand eight hundred
and fifty-six.
