THE NOVEL APPLICATION OF A CERTAIN ROOT TO THE MANUFACTURE OF STARCH PAPER AND CARDBOARD
Year: 1856

page_text: LETTERS PATENT to Adolphe Aubril, of Newman Street, Oxford Street,
in the County of Middlesex, Chymist, for the Invention of "THE NOVEL
APPLICATION OF A CERTAIN ROOT TO THE MANUFACTURE OF STARCH PAPER
AND CARDBOARD."
Sealed the 14th April 1857, and dated the 28th October 1856.
PROVISIONAL SPECIFICATION left by the said Adolphe Aubril at the
Office of the Commissioners of Patents, with his Petition, on the 28th
October 1856.
I, ADOLPHE AUBRIL, of Newman Street, Oxford Street, in the County of
Middlesex, Chymist, do hereby declare the nature of the said Invention for
"THE NOVEL APPLICATION OF A CERTAIN ROOT TO THE MANUFACTURE OF STARCH
PAPER AND CARDBOARD," to be as follows:-
This Invention consists in the employment of the root commonly known
under the name of bryony for the manufacture of starch, the fibrous residuum
left after the separation of the starch therefrom being employed for the
manufacture of paper and cardboard, and other similar fabrics.
For this purpose I reduce the root to a pulverulent state by rasping, or
other mechanical means, and wash out or separate the starch therefrom, and
the fibrous residuum remaining after this operation I treat in the ordinary
well-known manner for. the manufacture of paper, cardboard, or other similar
fabrics.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPHE
AUBRIL, of Newman Street, Oxford Street, in tho County of Middlesex,
Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of October, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Adolphe Aubril, Her special license that I, the said Adolphe Aubril, my
executors, administrators, and assigns, or such others as I, the said Adolphe
Aubril, my executors, administrators, and assigns, should at any time agreo
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
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "THE NOVEL APPLICATION OF A
CERTAIN ROOT TO THE MANUFACTURE OF STARCH PAPER AND CARDBOARD," upon
the condition (amongst others) that I, the said Adolphe Aubril, 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 dato
of the said Letters Patent.
NOW KNOW YE, that I, the said Adolphe Aubril, 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 statement
(that is to say)
:
This Invention consists in the employment or novel application of the root
commonly known under the name of bryony for the manufacture of starch
paper and cardboard, the fibrous residuum left after the separation of the
starch therefrom being applicable for the manufacture of paper, cardboard, and
other similar fabrics, instead of the materials usually employed for theṣo
purposes.
In carrying out the object of my discovery, the root is to be reduced to a
coarse pulverulent state by rasping, or other mechanical means, and I then
wash out or separate the starch therefrom in a similar manner to that usually
adopted for extracting starch from potatoes. The fibrous residuum remaining

page_text: after this operation is to be treated with a caustic lye, and when the pulp is
prepared it may be manufactured according to any of the ordinary well-known
methods into paper, cardboard, or other similar fabrics.
In order to prepare the paper pulp from the fibrous parts of the root of the
bryony plant remaining after the abstraction or separation of the starch there-
from, I take the fibrous residuum and place it in a large vat or other suitable
vessel, and add thereto a caustic lye, weighing or marking from four to five
degrees of the alkalimeter. This lye should be sufficient to entirely cover the
pulp to the depth of two feet. I then allow the mass to boil for about two
hours, after which the lye must be drawn off and the pulp washed in water
until no caustic taste remains. After this operation, the pulp is submitted to
a second washing in cold water, with the addition of sulphuric acid weighing
or marking two degrees of Beaumé. The pulp is again washed in clean cold
water to remove the acid, and then it is fit to be used in the manufacture of
paper or cardboard.
I would here remark, that hydrochloric may be substituted for sulphuric
acid, and that the caustic lyes may be made either of caustic potash or caustic
soda.
Having now explained my Invention or discovery of the novel application of
a certain root to the manufacture of starch paper and cardboard, and the
manner of carrying the same into effect, I would observe, in conclusion, that
although I have described a mode of treating the fibrous residuum of the root
of the bryony plant (after the starch has been separated therefrom) in order to
prepare the same for the manufacture of paper and cardboard, I do not mean to
confine myself to such process, nor do I intend to claim the same as of my
Invention; but that which I consider to be new in the above-described Invention
or discovery, and desire to secure by Letters Patent, is, the novel application of
the root of the bryony plant to the manufacture of starch paper and cardboard.
In witness whereof, I, the said Adolphe Aubril, have hereunto set my
hand and seal, the Fifteenth day of April, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness,
FRED. WALKDEN,
