page_text: LETTERS PATENT to Joachim John Monteiro, of Brunswick Villas,
Hill Road, Abbey Road, in the County of Middlesex, Mining
Engineer, for the Invention of "IMPROVEMENTS IN THE TREATMENT OF
FIBROUS SUBSTANCES, AND IN THE APPLICATION OF THE SAME FOR THE PRO-
DUCTION OF PAPER, PASTEBOARD, CARTON PIERRE, PAPIER MACHÉ OR OTHER
SIMILAR PRODUCTS.”
Sealed the 6th February 1872, and dated the 21st August 1871.
PROVISIONAL SPECIFICATION left by the said Joachim John Monteiro
at the Office of the Commissioners of Patents, with his Petition,
on the 21st August 1871.
I, JOACHIM JOHN MONTEIRO, of Brunswick Villas, Hill Road, Abbey
5 Road, in the County of Middlesex, Mining Engineer, do hereby declare
the nature of my said Invention for ." IMPROVEMENTS IN THE TREATMENT OF
FIBROUS SUBSTANCES, AND IN THE APPLICATION OF THE SAME FOR THE PRODUCTION

page_text: OF PAPER, PASTEBOARD, CARTON PIERRE, PAPIER MÀCHÉ, OR OTHER SIMILAR
PRODUCTS," to be as follows:—
This Invention relates to the application and to the preparation
of what is known as Adamsonia fibre in and for the production of
paper, pasteboard, carton pierre, papier mache, or other similar products,
and consists in firstly subjecting the fibro as it occurs in commerce
to a disintegrating process, and then subjecting the disintegrated and
cleansed fibre to the action of an alkaline solution, and subsequently to
the action of bleaching agents, such, for example, as chloride of lime,
either alone or in conjunction with an acid, such, for example, as hydro-
chloric acid. The product thus resulting may either be employed alone
for the production of paper, pasteboard, carton pierre, or papier maché,
or it may be mixed with other fibrous materials. The proportion in which
the prepared Adamsonia fibre may be employed in conjunction with
other fibrous materials will vary according to the quality of the paper it 1
is desired to produce, but I have found that good results may be obtained
by the employment of about fifty parts by weight of the prepared
Adamsonia fibre to about fifty parts by weight of esparto straw or other
fibrous materials.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jaochim John Monteiro in the Great Seal Patent
Office on the 19th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOACHTM
JOHN MONTEIRO, of Brunswick Villas, Hill Road, Abbey Road, in the
County of Middlesex, Mining Engineer, send greeting.
WHEREAS IIer most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of August, in the
year of our Lord One thousand eight hundred and seventy-one, in the
35th year of Her reign, did, for Herself, Her heirs and successors,

trators, and assigns, or such others as I, the said Joachim John Monteiro,
my executors, administrators, or assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during

page_text: •
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 "IMPROVEMENTS -
IN THE TREATMENT OF FIBROUS SUBSTANCES, AND IN THE APPLICATION OF THE SAME
FOR THE PRODUCTION OF PAPER, PASTEBOARD, CARTON PIERRE, PAPIER MACHÉ, OR
OTHER SIMILAR PRODUCTS," upon the condition (amongst others) that I,
the said Joachim John Monteiro, my.executors or administrators, 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 Joachim John Monteiro, do licreby
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:
-
My said Invention relates to the application and to the preparation of
what is known as Adansonia fibro in and for the production of paper,
pasteboard, carton pierre, papier maché, or other similar products, and
consists in firstly subjecting the fibre as it occurs in commerce to a
disintegrating process, and then subjecting the disintegrated and cleansed
fibre to the action of an alkaline solution, and subsequently to the action
of bleaching agents, such, for example, as chloride of lime, either alone
or in conjunction with an acid, such, for example, as hydrochloric acid.
The product thus resulting may either be employed alone for the pro-
duction of paper, pasteboard, carton pierre, or papier maché, or it may
be mixed with other fibrous materials. The proportion in which the
prepared Adansonia fibre may be employed in conjunction with other
fibrous materials will vary according to the quality of the product it is
desired to produce, but I have found that good results may be obtained
by the employment of about fifty parts by weight of the prepared
Adansonia fibre to about fifty parts by weight of esparto straw or
other fibrous materials.
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 would observe in conclusion that 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
5°

page_text: and use to and in the production of paper, pasteboard, carton pierre,
papier maché, and other similar products of Adansonia fibre prepared
in a manner similar to that hercin set forth, and used either alone or in
combination with other fibrous materials.
In witness whereof, I, the said Joachim John Monteiro, have to 5
'this my Specification set my hand and seal, the Seventeenth day
of February One thousand eight hundred and seventy-two.
JOACHIM JOHN MONTEIRO. (L.S.)
