Year: 1873

page_text: LETTERS PATENT to Marcellin Réné Bouju, Merchant, of 69, Rue
d'Aboukir, Paris, France, for the Invention of “IMPROVEMENTS IN
APPARATUS FOR THE MANUFACTURE OF CARDBOARD AND PAPER PULP FROM
COMPLETE SPECIFICATION filed by the said Marcellin Réné Bouju
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 14th July 1873, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MARCELLIN
RENÉ BOUJU, Merchant, of 69, Rue d'Aboukir, Paris, France, send
greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN APPARATUS FOR THE MANUFACTURE OF CARDBOARD AND PAPER PULP FROM
VEGETABLE PLANTS AND FILAMENTOUS AND FIBROUS SHRUBS," and have petitioned
Her Majesty to grant unto me,
executors, administrators,
and assigns, Her Royal Letters Patent for the same, and have made
solemn Declaration that I the said Marcellin Réné Bouju am the truc
and first Inventor thereof.

page_text: NOW KNOW YE, that I, the said Marcellin Rene Bouju, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement and accompanying Drawings, that is to say :-
The apparatus herein described is specially adapted to the reduction of
the filaments of vegetable plants growing in hot climates, for converting
them into paper pulp, for the manufacture of card, paper of all kinds
and qualities, and papier maché articles.
In the preparation of the pulp the substance employed consists of 1
filamentous plants, such for instance as the hibiscus esculentum, gombo,
and others of a fibrous nature. These plants are subjected to a treat-
ment destined to reduce them to small threads by means of special
machinery.
The matter employed is first submitted to the action of water, in which 1
it is soaked some time. This preparation gives consistency to the
matter and prevents its reduction to powder, which would render it
useless. When withdrawn from the water it is crushed by the apparatus
represented in the accompanying Drawings.
Fig. 1 is a front view or elevation of my apparatus; Fig. 2 is a 2
sectional elevation of the same; Fig. 3 represents a movable wheel in
detail, hereafter mentioned; Fig. 4 is a plan of a fixed wheel, also
further described. A is the axis of the above-named wheels; B, the
frame of the apparatus; C, the funnel for supplying it; D, a plumber
block supporting the pivoting end of the axis or shaft A; L is the 2
discharge pipe; M, a reservoir or receptacle of the material when
crushed.
-
Figs. 5, 6, 7, and 8, represent slight modifications of the same
apparatus. T, Figs. 6 and 7, is a cast-iron case furnished with grooves
forming the cone of the crushers;B V is the correspondent part of the 3
same. The same letters of reference indicate like parts in the several
Figures.
The machine consists of a cast-iron frame B surmounted by the funnel
C, and two wheels R, and R', placed one above the other horizontally
in a cylindrical iron case E. One of these wheels R is movable and 3
turns on its axis A, which consists of a shaft traversing the two wheels;

page_text: the end of the shaft A rests on a plumber block D. The gear wheels K
placed at the end of the shaft A communicate with the toothed wheels
of the governing shaft by aid of a pinion or toothed wheel fixed to the
shaft for the purpose, and for establishing between the governing shaft
and that of the apparatus the requisite rotary motion necessary for
working the wheels. The wheel R is fixed and receives motion from
the upper one R¹; this fixed wheel bears on its upper surface and in its
centre a circular opening to leave room for the movement and action
of a cutting and crushing blade C³, necessary for the operation of
crushing and triturating the fibres. The horizontal internal surface of
the wheels R, R¹, is dressed in the usual manner. M is a reservoir
destined to receive the matter when crushed, after which latter operation
it is washed and bleached.
The dimensions of the apparatus would naturally vary according to
the amount of manufacture, and it may be worked by steam, hydraulic
pressure, or otherwise.
I claim as my Invention the apparatus herein described and illustrated
by the accompanying Drawings for crushing and reducing to pulp the
filaments of fibrous plants for conversion into paper of all kinds, card,
and papier maché.
In witness whereof, I, the said Marcellin Réné Bouju, have
M. R. BOUJU. (L.S.)
