EDMUND HUNT, of Glasgow, in the County of Lanark, North Britain Patent
Agent, "IMPROVEMENTS IN SUGAR-CANE MILLS which Invention has been
communicated to me from abroad by James Thomson and John Black, Engineers,
residing at Campos in the Empire of Brazil,
This Invention has for its object to improve the action of sugar-cane mills; and
in carrying it out three rolls are arranged in the ordinary way and are of the
ordinary kind, there being two lower rolls and a single upper one placed above and
between the others. By the present Invention two more rolls are added and are
placed at a higher level and so that the cranes which pass first between the two
added rolls may descend from them to the three rolls. The two additional
rolls are for the purpose of subjecting the canes to a preparatory splitting and
partial crushing action with the view of bringing them into a condition to be more
easily and completely acted on by the ordinary three rolls. The preparatory rolls
are made with comparatively deep angular grooves running round them and the
ridges between the grooves of one roll face or enter the grooves of the other roll
this construction operating effectually to split and crush the canes.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Edmund Hunt in the Great Seal Patent Office on the 28th November
1882.

EDMUND HUNT, of Glasgow, in the County of Lanark, North Britain, Patent
Agent. "IMPROVEMENTS IN SUGAR CANE MILLS A communication to me from
abroad by James Thomson and John Black, Engineers residing at Campos in the
Empire of Brazil.
The said Invention has for its object to improve the action of sugar-cane mills;
and in carrying it out three rolls are arranged in the ordinary way and are of the

page_text: ordinary kind, there being two lower rolls and a single upper one placed above and
between the others.
By the present Invention two more rolls are added and are placed at a higher
level and so that the canes which pass first between the two added rolls may
descend from them to the three rolls. The two additional rolls are for the purpose
of subjecting the canes to a preparatory splitting and partial crushing action, with
the view of bringing them into a condition to be more easily and completely acted
on by the ordinary three rolls.
And in order that the said Invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and representing a sugar-cane mill as made with the
improvements.
Figures 1 and 2 are side and end elevations of the improved sugar-cane mill, the
'entering end being shown in figure, 2, with part of the casing supposed to be
broken away. Figure, 3, is a plan; and figure, 4, is an enlarged view of portions
of the additional rolls showing the configuration of their surfaces. In these
drawings the same reference numerals are used to mark the same or like parts
wherever they are repeated.
In so far as relates to the ordinary three rolls 5, 6, 7, the framing, 8, is
constructed substantially as usual, whilst special frame pieces 9, 10, are added to
carry the additional pair of rolls, 11, 12, these frame pieces being bolted to each
other and to the main frame, 8. The ordinary rolls 5, 6, 7, are geared together in
the ordinary way; and whilst the two additional rolls, 11, 12, are similarly geared
to each other they are driven by means of a pair of spur wheels, 13, 14, one of
which is fast on the journal of the uppermost, 5, of the three rolls, the other being
fast on the journal of the lower additional roll, 12. A guide hopper or casing, 15,
is placed so as to lead the canes first in between the two additional rolls, 11, 12,
after passing which rolls, the caries proceed along a downwardly inclined guide and
pass through between the three rolls 5, 6, 7, in the ordinary way.
The additional or preparatory rolls 11, 12, are made with comparatively deep
angular grooves as shown in figure, 4, these grooves running round the rolls; and
the ridges between the grooves of one roll face or enter the grooves of the other
roll, this construction operating effectually to split and crush the canes.
Having thus particularly described the said Invention and the manner of
performing the same I have to state that I do not restrict myself to the precise
details herein described or delineated but that what I believe to be novel and
original and claim as the Invention secured to me by and in terms of the herein-
before in part recited Letters Patent is :-
The combination of a pair of deeply grooved preparatory rolls with the three
rolls of ordinary sugar-cane mills substantially as and for the purposes hereinbefore
described.
In Witness whereof I, the said Edmund Hunt, have hereunto set my hand
and seal this twenty-seventh day of November, in the year of our Lord
One thousand eight hundred and eighty-two.
