CERTAIN IMPROVEMENTS IN MANUFACTURING PAPER, PASTEBOARD, AND PULP
Year: 1855

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of CERTAIN
IMPROVEMENTS IN MANUFACTURING PAPER, PASTEBOARD, AND PULP."-A com-
munication from F. V. Pinondel de la Bertoche, of Paris.
Sealed the 15th January 1856, and dated the 1st August 1855.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Broonian
at the Office of the Commissioners of Patents, with his Petition, on the
1st August 1855.
J, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for CERTAIN IMPROVEMENTS IN MANUFACTURING PAPER, PASTEBOARD, AND PULP,"
(communicated to me by H. V. Pinondel de la Bertoche, of Paris,) to be as
follows:-
The Invention consists, first, in the employment of the root of the asphodel
plant, and the remains of such root after distillation, for the manufacture of
paper, card, and pasteboard, pulp for paper, for inouldings, &c., either alone
or mixed with other ingredients used for such purposes; and, second, in the
treatment of the asphodel root, or its remains after distillation, in order to
form it into pulp, paper, pasteboard, cardboard, &c.

page_text: Treatment of the root.-After the root has been freed from the plant and
leaves, it is carefully washed, then cut, and bruised, rasped, or crushed, according
to the use to which it is intended to be applied. The root is next submitted
to pressure, in order to deprive it of its moisture, and for this purpose I prefer
hydraulic pressure. The fibrous or pulpy remains are gathered from the press
and undergo further preparation, as hereafter stated.
The asphodel root in a dry state, whether after distillation, or whether
moisture has been otherwise extracted from it, or when it has been reduced to
the state of a filamentous and ligneous pulp, is prepared as follows:―
Ist preparation. The asphodel root in the state last described is washed in
cold water, in order to separate all foreign matters from it; it is next placed
in a tepid bath, to which is added a dose of some alkali, such as potass, soda,
or other more or less active alkali, and in quantities varying with the intended
use of the pulp, and the quality of the paper, &c. to be manufactured. The
pulpy mass remains in this alkaline bath until the fibres separate readily from
cach other, but rupture in the fibres themselves must as far as possible be
prevented. In order to make grey or brown paper, cardboard, pasteboard, and
the like, no further chemical treatment is necessary, it being only requisite to
cause the pulp to undergo the ordinary mechanical processes followed in
making such papers and boards.
2nd preparation.-For the finer descriptions of paper and products, the
fibrous pulp of the asphodel must be more completely bleached, either by
chlorine, or by other means followed for the bleaching of pulp in the manu-
facture of paper, after which it is treated as ordinary pulp, in order to form it
into paper, cardboard, &c.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 23rd January 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of August, in the year of our Lord
One thousand eight hundred and fifty-five, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,

page_text: the said Richard Archibald Brooman, Her special licence that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns, or
such others as I, the said Richard Archibald Brooman, my executors,
administrators, and 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 vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "CERTAIN IMPROVEMENTS IN MANUFACTURING
PAPER, PASTEBOARD, AND PULP," (communicated to me by H. V. Pinondel de
la Bertoche, of Paris,) upon the condition (amongst others) that I, the said
Richard Archibald Brooman, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the samo 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 Richard Archibald Brooman, 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 thereof, that is to say :-
The Invention consists, first, in the employment of the root of the asphodel
plant, and the remains of such root after distillation, for the manufacture of
paper, card, and pasteboard, pulp for paper, for mouldings, &c., either alone
or mixed with other ingredients used for such purposes; and, second, in tho
treatment of the asphodel root, or its remains after distillation, in order to
form it into pulp, paper, pasteboard, cardboard, &c.
Treatment of the root. After the root has been freed from the plant and
leaves, it is carefully washed, then cut, and bruised, rasped, or crushed, according
to the use to which it is intended to be applied. The root is next submitted
to pressure, in order to deprive it of its moisture, and for this purpose I prefer
hydraulic pressure. The fibrous or pulpy remains are gathered from the press
and undergo further preparation, as hereafter stated.
The asphodel root in a dry state, and whether after distillation, or whether
moisture has been otherwise extracted from it, or when it has been reduced to
the state of a filamentous and ligneous pulp, is prepared as follows:-
First preparation.-The asphodel root in the state last described is washed
in cold water, in order to separate all foreign matters from it; it is next placed
in a tepid bath, to which is added a dose of some alkali, such as potash, soda,
lime, or other more or less active alkali, and in quantities varying with the
intended use of the pulp, and the quality of the paper, &c. to be manufactured.

page_text: The pulpy mass remains in this alkaline bath until the fibres separate readily
from each other, but rupture in the fibres themselves must as far as possible
be prevented. In order to make grey or brown paper, cardboard, pasteboard,
and the like, no further chemical treatment is necessary, it being only requisite
to cause the pulp to undergo the ordinary mechanical processes followed in
making such
papers and boards.
Second preparation. For the finer descriptions of paper and products; the
fibrous pulp of the asphodel must be more completely bleached, either by
chlorine, or by other means followed for the bleaching of pulp in the manu-
facture of paper, after which it is treated as ordinary pulp, in order to form it
into paper, cardboard, &c. The asphodel pulp may either be used alone, or
it may be combined with other ingredients employed in the manufacture of
paper, pasteboard, cardboard, mouldings, and the like.
And having now described the nature of the said Invention, and in what
manuer the same is to be performed, I declare that I claim,-
First, the employment of the root of the asphodel plant, and the remains
of such root after distillation, either alone or combined with other suitable
ingredients, for the manufacture of paper, cardboard, pasteboard, and pulp for
paper, mouldings, and other purpose to which pulp has been or may be
applied.
Second, the treatment of the asphodel root, or of its remains after distillation,
as herein-before described, in order to form it into pulp, paper, pasteboard,
cardboard, &c.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-third day of January, One
thousand eight hundred and fifty-six.
R. A. BROUMAN. (L.S.)
