IMPROVEMENTS IN THE APPLICATION AND IN THE PRE- PARATION OF CERTAIN FIBRES FOR THE PRODUCTION OF PAPER AND TEXTILE FABRICS
Year: 1864

page_text: LETTERS PATENT to John Adam and John Webb, both of 4, Lawrence
Pountney Hill, in the City of London, Merchants, and Joachim John
Monteiro, of 29, Harewood Square, in the County of Middlesex, for
the Invention of "IMPROVEMENTS IN THE APPLICATION AND IN THE PRE-
PARATION OF CERTAIN FIBRES FOR THE PRODUCTION OF PAPER AND TEXTILE
FABRICS."
Sealed the 24th January 1865, and dated the 11th August 1864.
PROVISIONAL SPECIFICATION left by the said John Adam, John Webb,
and Joachim John Monteiro at the Office of the Commissioners of
Patents, with their Petition, on the 11th August 1864.
We, JOHN ADAM and JOHN WEBB, both of 4, Lawrence Pountney Hill, in
the City of London, Merchants, and JOACHIM JOHN MONTEIRO, of 29, Hare-
wood Square, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE APPLICATION AND IN THE PREPARATION
OF CERTAIN FIBRES FOR THE PRODUCTION OF PAPER AND TEXTILE FABRICS," to be
as follows:-
This Invention consists in the use and employment of the fibre obtained
from the bark of the adansonia digitata for the production of paper and for
the manufacture of textile fabrics.
Having previously removed the external covering or outer bark, and having
obtained the inner bark, either by stripping or otherwise, it is either to be

page_text: dried or desiccated previously to, or it may at once be passed through rollers
or other machinery suitable for effecting its disintegration, so as to free it from
sap, gum, and other matters. The crude fibre resulting from this process is
then to be further purified by repeated washings with water, and if requisite
may be further subjected to the action of an alkaline solution, and may, after
having been so subjected, and subsequently washed if necessary, be submitted
to any of the well-known bleaching processes for cotton and other fibres, either
with chloride of lime and an acid or otherwise, as is well understood. When
the fibre so obtained is to be employed for the manufacture of paper, we
employ it either alone or in conjunction with other fibres or substances in the
same manner as sparte and other fibres are now employed. The fibres after
having been separated from the vegetable and other matters with which they
are originally associated by means of suitable rollers, beaters, or scutching
apparatus or by other suitable means, may, after having been submitted to a
washing or cleansing process, be either directly employed alone or by pre-
ference with the admixture of other fibres for the production of textile fabrics,
or they may be previously submitted to a bleaching process in the same
manner as cotton and flax are now bleached and as is well understood.
SPECIFICATION in pursuance of the conditions. of the Letters Patent, filed
by the said John Adam, John Webb, and Joachim John Monteiro
in the Great Seal Patent Office on the 7th February 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
ADAM and JOHN WEBB, both of 4, Lawrence Pountney Hill, in the City of
London, Merchants, and JOACHIM JOHN MONTEIRO, of 29, Harewood Square,
in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Eleventh day of August, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto.
us, the said John Adam, John Webb, and Joachim John Monteiro, Her.
special license that we, the said John Adam, John Webb, and Joachim John.
Monteiro, our executors, administrators, and assigns, or such others as we,
the said John Adam, John Webb, and Joachim John Monteiro, our execu-
tors, 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 vènd, within

page_text: the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN THE APPLICATION AND IN THE
PREPARATION OF CERTAIN FIBRES FOR THE PRODUCTION OF PAPER AND TEXTILE
FABRICS," upon the condition (amongst others) that we, the said John Adam,
John Webb, and Joachim John Monteiro, our executors or administrators,
by an instrument in writing under our hands and seals, or under the hand
and seal of one of us or them, 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 we, the said John Adam, John Webb, and
Joachim John Monteiro, do hereby declare the nature of our 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 use and employment of the fibre obtained
from the bark of the adansonia digitata for the production of paper and for
the manufacture of textile fabrics.
The manner in which we prepare the fibre is the following:-Having
previously removed the external covering or outer bark, and having obtained
the inner bark, either by stripping or otherwise, it is either to be dried or
dessicated previously to, or it may at once be passed through rollers or other
machinery suitable for effecting its disintegration, so as to free it from sap,
gum, and other matters. The crude fibre resulting from this process is then
to be further purified by repeated washings with water, and if requisite may
be further subjected to the action of an alkaline solution; and after having
been so subjected and subsequently washed with water may, if necessary, be
submitted to any of the well-known bleaching processes now generally adopted
for the bleaching of cotton or other fibres, either by the employment of a solu-
tion of chloride of lime and an acid or otherwise, as is well understood. When
the fibre so obtained is to be employed for the manufacture of pulp or paper,
we employ it either alone or in conjunction with other fibres or substances in
the same manner as esparto or sparte and other fibres are now employed.
When it is desired to prepare the fibres for the production of textile, woven,
or other fabrics, the fibres after having been separated from the vegetable and
other matters with which they were originally associated by means of suitable
rollers, beaters, scutching apparatus or other suitable means may, after having
been submitted to a washing or cleansing process, be either directly employed
alone or, by preference, with the admixture of other fibres, or they may be

page_text: previously submitted to a bleaching process in the same manner as cotton and
flax are now bleached, and as is well understood.
What we claim as our Invention is the employment of the fibrous portion
of the inner bark of the adansonia digitata after having been subjected to
suitable treatment or preparation for the manufacture and production of
paper, and also for the manufacture and production of textile or woven fabrics,
in the manner herein described.
In witness whereof, I, the said John Adam, on behalf of myself and my
aforesaid Co-patentees, have hereunto set my hand and seal, this
Sixth day of February, One thousand eight hundred and sixty-five.
JOHN ADAM.
