PROVISIONAL SPECIFICATION left by the said Douglas Allport at the
Office of the Commissioners of Patents, with his Petition, on the
5th October 1875.
I, DOUGLAS ALLPORT, of No. 9, Fenchurch Buildings, in the City of
London, in the County of Middlesex, Merchant, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN EXTRACTING SUGAR
FROM SUGAR CANE, AND IN UTILIZING THE RESIDUAL PRODUCTS," to be as
follows:-
With the view of extracting more of the saccharine matter present in
sugar canes than is now obtained I take the megass or crushed cane and

page_text: reduce the same into a finely disintegrated mass or pulp by grinding it
in a mill suited for the purpose. I then saturate the pulp with cano
juice and steam, or either, and subject it to pressure in a hydraulic or
other press suitable for the purpose of extracting its moisture.
The sweet fluid expressed from the saturated pulp is treated as usual 5
for the manufacture of sugar or rum, and the cake or pressed pulp being
dried by forcing it through a tube in contact with the heated air is
available for fuel or paper stock.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Douglas Allport in the Great Seal Patent Office ]
on the 5th April 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DOUGLAS

it in a mill suited for the purpose. I then saturate the pulp with cane
juice and steam, or either, and subject it to pressure in a hydraulic or
other press suitable for the purpose of extracting its moisture.
The sweet fluid expressed from the saturated pulp is treated as usual
for the manufacture of sugar or rum, and the cake or pressed pulp being
dried by forcing it through a tube in contact with heated air is available
for fuel or paper stock.
I claim. the reduction into pulp or powder of sugar cane megass, the
saturation of such pulp, and the expression therefrom of its fluid
particles, as well as the drying of the cake resulting therefrom for fuel
or paper stock, as herein described.
In witness whereof, I, the said Douglas Allport, have hereunto
set my hand and scal, this Fourth day of April, in the year
