Republic of France.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for “ IMPROVEMENTS IN THE TREATMENT OF SUGAR CANE FOR THE
MANUFACTURE OF SUGAR AND OF PAPER PULP, AND IN THE MACHINERY OR
APPARATUS EMPLOYED THEREIN," a communication to me from abroad by
Jean Baptiste Java Mignon and Stanislas Henri Rouart, both of Paris,
in the Republic of France, to be as follows:-
This Invention has for its object treating sugar cane in such a manner
as to render the extraction of the juice more complete, in order to obtain
an increased yield of sugar, which result has also the effect of bringing

the cane trash into a better condition for the manufacture of paper, for
which purpose it may be utilized.
Sugar cane consists of a strong tube having a number of knots. In
the small reservoirs thus formed the saccharine juice is enclosed, the
extraction of which juice is according to the ordinary process only
partially effected. The rollers employed acting upon a great thickness
of cane are consequently unable to completely crush it; the expulsion
of the juice is therefore difficult, whence results the necessity for limiting
the speed at which the apparatus is worked.
According to this Invention it is proposed to split the cane in the 1
direction of its length before it is subjected to the actual or final crushing
operation.
The apparatus employed in carrying out this Invention consists of a
rolling mill with, say, two rollers, and having a blade or knife placed
between the two rollers, with its edge parallel with their axis. The axes]
of the rollers are placed in guide blocks allowing of the bearings being
brought together, so as to regulate the distance between them; the blade
or knife is also moveable in such a manner that its position may be
adjusted.
The rollers are arranged at such a distance apart as to compress the
cane, to carry it forward, and crush it a little, in order to cause it to
form a continuous sheet. This sheet on reaching the blade of the knife
will be divided in two sheets, which may be guided in the desired
direction by means of guides suitably situate; they are then brought
opposite a set of, say, four rollers, forming two rolling mills. The
middle rollers of this set may be slightly fluted, so as to facilitate the
crushing of the fibres.

When the cane has been subjected to the washing operation necessary
for removing as nearly as possible the whole of the juice contained
therein it may be introduced into a machine analogous to that for which
Letters Patent were obtained 5 November 1874, No. 3819, for the
manufacture of paper pulp, but arranged so as to receive the cane cut
up for the purpose into pieces of a suitable length. In this apparatus
the cane will be reduced to a more or less liquid and fine pulp, according
to the quantity of water introduced and the degree of fineness of the a
comb teeth.

removed by submitting it to a sufficient pressure, after which it may be
arranged in blocks to be forwarded to the places where the paper is to be
manufactured.
