Year: 1855

page_text: LETTERS PATENT to Jean Pechgris de Frontin, of Agen, Empire of France
and of 32, Essex Street, Strand, London, for the Invention of "THE USE
OF A NEW MATERIAL IN THE MANUFACTURE OF PAPER AND PASTEBOARD."
Sealed the 80th October 1855, and dated the 4th May 1855.
PROVISIONAL SPECIFICATION left by the said Jean Pechgris de Frontin
at the Office of the Commissioners of Patents, with his Petition, on
the 4th May 1855.
I, JEAN PECHGRIS DE FRONTIN, of Agen, Empire of France, and of 32,
Essex Street, Straud, London, do hereby declare the nature of the said Inven-
tion for "THE USE OF A NEW MATERIAL IN THE MANUFACTURE OF PAPER AND
PASTEBOARD" to be as follows:-
This Invention relates to the use of vegetable substances, or matter derived
from certain plants which have never before been applied, to the manufacture
of paper and pasteboard. These plants are, the acacia tree, which yields a
very good fibrous matter; the various kinds of the annual plant called lupine;
the plant called bryonia, the stalks of which are used and also the roots after
the amylaceous matter has been extracted, the latter of which may also be
applied in any suitable way to sizcing the paper in the pulp, or after; the
stalks of the bulbous plant called topinambour, or Jerusalem artichoke, and
the residue of the bulbs of said plant after the saccharine matter has been
extracted from them; and also stalks of the different kinds of sunflower or
heliotropium. These plants or vegetable parts being used separately or in

page_text: various combinations with each other yield a pulp which is fit for making
paper and pasteboard without the admixture of other stock, such as rags; and
most of the above plants being agricultural ones, the production of the raw
material is thus unlimited, and at the same time a useful employ found for the
The modes which I use for
waste parts of some agricultural products.
reducing these vegetable matters into pulp do not differ from the chemical
processes now employed for other vegetable matters, i. c., maceration, steeping,
and washing and bleaching.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Pechgris de Frontin, in the Great Seal Patent Office
on the 2nd November 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
PECHGRIS DE FRONTIN, of Agen, Empire of France, and of 32, Essex Street,
Strand, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of May, in the year of our Lord One
thousand eight hundred and fifty-five, in the eighteenth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Jean
Pechgris de Frontin, Her special licence that I, the said Jean Pechgris de
Frontin, my executors, administrators, and assigns, or such others as I, the said
Jean Pechgris de Frontin, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 USE OF A NEW
MATERIAL IN THE MANUFACTURE OF PAPER AND PASTEBOARD," upon the condition
(amongst others) that I, the said Jean Pechgris de Frontin, 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 Jean Pechgris de Frontin, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement:―

page_text: These improvements relate to the use of five plants for the manufacture of
paper and pasteboard, which vegetable substances or matters derived from
them have never before been applied for this purpose.
Whether I use them singly, or all together, or mixed with any other pulp
of rags or any other substance, they are apt to produce a raw material fit for
the manufacture of paper; and agriculture, which will benefit by it, will
afford those plants in as sufficient quantity as may be required for the wants
of industry.
These plants are, first, the acacia tree, which yields a very good fibrous
matter; second, the varicus kinds of the annual plant called lupine; third, the
plant called bryonia, the stalks of which are used and also the roots after the
amylaceous matter has been extracted; the latter may also be applied in any
suitable way to sizing the paper in the pulp, or after; fourth, the stalks of the
bulbous plant called topinambour, or Jerusalem artichoke, and the residue of
the bulbs of said plant after the saccharine matter has been extracted from
them; fifth, and also the stalks of the different kinds of heliotropium or sun-
flower. The modes which I use for reducing these vegetable matters into
pulp do not differ from the chemical process now employed for other vegetable
matters, which are, maceration, steeping, washing, and bleaching.
Having thus described the nature of my Invention, and the manner in
which the same is or may be carried into effect, I wish it to be distinctly
understood that what I claim as novel, & being secured to me by the herein-
before in part recited Letters Patent, is, manufacturing paper & pasteboard
with pulps extracted from the five plants or vegetable substances above
specified, whether I use for the production of said pulps one single plant, or
several plants, or parts of the same, or all combined together, yet reserving
the faculty of mixing the pulps of my own Invention with other pulps
generally employed in the manufacture of paper & pasteboard.
In witness whereof, I, the said Jean Pechgris de Frontin, have hereunto
set my hand and seal, this Thirtieth day of October, in the year of our
Lord One thousand eight hundred & fifty-five.
J. P. DE FRONTIN. (LS.)
