AN IMPROVED PRESS
Year: 1884

page_text: I JOSEPH URBAIN, of No. 29 Rue Raspail, Ivry-sur-Seine, in the republic of
France, Civil Engineer, do hereby declare the nature of the said invention for
"AN IMPROVED PRESS
" to be as follows:-
My invention relates to an improved roller press. The improved press is
constructed of two rows of rollers or cylinders; the lower row of which consists
of a series of solid or hollow metallic rollers the axes of which are parallel and
they are moved by means of an endless screw gearing into pinions placed on cach
of the axes, or by any other suitable mechanical means. The space between the
rollers or cylinders is partly filled up (at the upper part) with wedge shaped metal
bars which bars may be provided with notches in which are placed smaller rollers
to facilitate the sliding of the substances. The pressing rollers are divided into
series, each series being surrounded by an endless apron and placed over a trough
into which falls the liquid resulting from the pressure. The upper row of rollers
or cylinders is similarly arranged but in such a manner that the vertical distance
between the two first rollers of the first series is greater than the vertical distance
between the two last rollers of the second series.
By this arrangement the substances introduced receive an increased pressure in
proportion as they are drawn towards the end of the press.

page_text: I JOSEPH URBAIN of N° 29 Rue Raspail, Ivry-sur-Seine in the Republic of
France Civil Engineer do hereby declare the nature of the said invention for
"AN IMPROVED PRESS" and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to an improved roller press. The improved press consists
of two parts; one of the said parts (either the receiving or the discharge end) is
a cold press and the other part is a hot press. This division however is not
indispensable and I may construct the whole of my improved press with hot rollers
or cylinders or with cold rollers or cylinders.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawing in which figure 1, is a longitudinal
section of a press constructed according to my invention; figure 2, is a detached
sectional view on a larger scale of a portion of the press.. Similar letters in both
the figures represent similar parts.
In carrying out my invention I arrange a first series of upper and lower
cylinders A, the said cylinders being either solid or hollow and of about twenty
centimeters in diameter and separated from one another by a small space so as
to give a total length of about four meters or more or less according to requirement.
These two rows of cylinders are not parallel but are inclined one towards the other
in such a manner that the space between the first cylinder of the upper row and
the first cylinder of the lower row at the entrance of the press shall be about eight
centimeters in height whilst the space at the other or outlet end is not more than
about five centimeters.
At the lower part of the upper row of cylinders and at the upper part of the
lower row of cylinders I place pieces m, of the same material as the cylinders, that
is to say, cast iron, bronze, or other metal or wood, the said pieces nearly
conforming in shape to the spaces, so as to form as shewn in the drawing one
continuous surface. In the middle of the pieces m, are rollers serving to facilitate
the sliding of the substances.
Over these two rows of cylinders passes an endless web or apron n.
Each of the cylinders receives movement in the direction indicated by the arrows
in figure 2, from gearing actuated by an endless screw, arranged on a shaft running
the length of the cylinders or by other suitable mechanical means.
The axes
of the cylinders are besides moveable vertically so as to allow of the rows being
brought nearer to or farther from each other at will to squeeze or loosen the
materials being pressed.
The second series of cylinders B, B, B, are hollow and heated by any suitable
means. Their arrangement is the same as that of the cylinders A. The two series
of cylinders are separated by a space J K.
To support the cylinders I provide a frame M, C, D, or other suitable frame and
below each of the series of cylinders A, and B, I place a sloping overflow shoot
conveying the liquid products to the bottom of the apparatus.
If the improved press be employed to press the products of stearine works the
cakes of material are introduced between the two first cylinders on the left hand
side of figure 1, and will be drawn by the movement of the cylinders and the
endless web or apron as far as the point marked J K, whence they will pass into
the hot press and be discharged at the right hand end of the press having been
then subjected to the maximum pressure.
The liquid products fall as hereinbefore described onto the overflow shoots.
It will be obvious that without departing. from the principle of my invention
I may vary the diameter and the number of the cylinders as well as the material

page_text: of which they are composed, the inclination of the series etc, the shape and
arrangement of the frames and also the manner of pressing and of actuating the
cylinders.
My improved press may be used with hot or cold or partly hot and partly cold
cylinders for pressing any required substances such as grapes, apples, pears and
other fruits, oleaginous seeds pulp and roots of all kinds, fatty bodies, fatty acids,
margarine, butter &c.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
A press consisting of a number of rotating cylinders separated by wedge shaped
pieces carrying antifriction rollers (the said cylinders being heated or not) in
combination with endless webs or aprons substantially as herein before described
and represented in the accompanying drawing.
