PROVISIONAL SPECIFICATION left by the said William Lloyd Wise at the
Office of the Commissioners of Patents on the 23rd January 1883.
WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields in the County of Middlesex
"IMPROVEMENTS IN APPARATUS FOR TREATING SUGAR CANE FROM WHICH JUICE
IS TO BE EXPRESSED" (a communication from La Société Anonyme des anciens
Etablissements Cail et Monsieur A. Ferron of Paris France)
This invention relates to the use in conjunction with a mill for expressing juice
from sugar cane of apparatus such as hereinafter described arranged in front of the
crushing rolls and designed to split up or divide the canes before they enter
between the crushing rolls.
This apparatus comprises two rolls (to be hereinafter called preliminary rolls)
with helicoidal channels and receives the canes which pass lengthwise between
them, being received by the rolls in a direction that is in a horizontal plane
parallel to the axes of the said rolls, and in vertical planes at right angles
thereto, These preliminary rolls as they rotate split the canes throughout their
length and in directions presenting the form of a more or less elongated helix
according to the different speeds at which the said rolls rotate; thus preparing tho
canes in such a manner that considerably less power will be necessary for sub-
sequently crushing them in the mill, whilst the extraction of the juice will be
facilitated and the yield will be increased.
The accompanying sheet of drawings will facilitate a clear understanding of the
nature of the invention.

page_text: Fig 1 is a side elevation of a combined apparatus embodying preliminary rolls as
aforesaid
Figs 2 and 3 represent to an enlarged scale the form and arrangement of the
threads on the two preliminary rolls.
As illustrated the apparatus is composed essentially of two preliminary rolls C
of suitable material such as cast iron, bronze or cast steel, and which may
conveniently be of the same length as the mill rolls with which the apparatus is
designed to be used
The preliminary rolls C have threads of peculiar forms and arrangements as
represented in Figs 2 and 3.
As indicated in these figures the section of these threads is in the form of a
right angled triangle, the thread of one roll is arranged in a contrary direction to
that of the other, so that as the rolls rotate these threads present a series of
helicoidal cutting blades acting similarly to shears; with this arrangement the
canes passing between the cylinders are split throughout their length in straight
or helical directions, according as the speeds of rotation of these two rolls are
equal or unequal.
Each roll may be provided with a right hand thread for nearly half its length,
and with a left hand thread for the other half these being separated by a gap
designed to receive a separating frame that will keep the sugar canes in the
helicoidal cutting grooves of the apparatus.
The rolls C are provided at their ends with journals turning in frames or
supports, and are geared by pinions which may be of equal or unequal diameters
according to the angle at which the canes are to be helically split by the cutting
edges of the preliminary rolls.
One preliminary roll is driven through a spur wheel B itself actuated from any
suitable source through a pinion D and shaft E.
In front of the apparatus is arranged a cane carrier F similar to that of an
ordinary mill, which brings the canes to the preliminary rolls C between which
they are split, and from which they are conducted direct to the crushing mill H
along an inclined plane G.

WILLIAM LLOYD WISE of 46 Lincoln's Inn Fields in the County of Middlesex
IMPROVEMENTS IN APPARATUS FOR TREATING SUGAR CANE FROM WHICH JUICE
IS TO BE EXPRESSED (a communication from La Société Anonyme des Anciens
Etablissements Cail et Monsieur A. Ferron of Paris France)
This invention relates to the use in conjunction with a mill for expressing juice
from sugar cane of apparatus such as hereinafter described arranged in front of the
crushing rolls and designed to split up or divide the canes before they enter
between the crushing rolls.
This apparatus comprises two rolls (to be hereinafter called preliminary rolls)
with helical grooves or channels (cannelures helicoidales) and receives the canes
which pass lengthwise between them, being received by the rolls in a direction
that is in a horizontal plane parallel to the axes of the said rolls, and in vertical
planes at right angles thereto. These preliminary rolls as they rotate split the
canes throughout their length, and in directions presenting the form of a inore or
less elongated helix according to the relative speeds at which the said rolls
rotate; thus preparing the canes in such a manner that considerably less power
will be necessary for subsequently crushing them in the mill, whilst the extraction
of the juice will be facilitated and the yield will be increased.
Referring to the accompanying sheet of drawings
Fig. 1 is a side elevation of a combined apparatus embodying preliminary rolls
for splitting up or dividing the canes as aforesaid. Fig. 2 is a plan and Fig 3 a
front elevation. Figs 4 and 5 represent to an enlarged scale the form and
arrangement of the threads on the two preliminary rolls.
The apparatus is composed essentially of two preliminary rolls C C' of suitable
material such as cast iron, bronze, or cast steel, and which, as shewn, may
conveniently be of the same length as the mill rolls with which the apparatus is
designed to be used.
The preliminary rolls C C¹ have threads of peculiar forms and arrangements as
represented in Figs. 4 and 5.
As indicated in these figures the section of the threads is in the form of a right
angled triangle—; the thread of one roll is arranged in a contrary direction to that
of the other, so that as the rolls rotate these threads present a series of belical
cutting blades (de lames helicoidales tranchantes) acting similarly to shears.
With
this arrangement the canes passing between the preliminary rolls are split through-
out their length in straight or helical directions, according as the speeds of rotation
of the two rolls are equal or unequal.
Each preliminary roll may, as shown, be provided with a right hand thread for
nearly half its length, and with a left hand thread for the other half these being
separated by a gap or recess designed to receive a separating frame that will keep
the sugar canes in the belical cutting grooves of the apparatus.
The rolls C C are provided at their ends with journals turning in frames or
supports A A, and are geared by pinions P P which may be of equal or unequal
diameters according to the angle at which the canes are to be helically split by the
cutting edges of the preliminary rolls.
One preliminary roll is driven through a spur wheel B itself actuated from any
suitable source through a pinion D and shaft E.
In front of the apparatus is arranged a cane carrier F similar to that of an

page_text: ordinary inill which brings the canes to the preliminary rolls C C₁ between which
they are split, and from which they are conducted direct to the crushing mill H
along an inclined plane or conveyor G.
Having described the nature of the said invention and the manner of carrying
it into practical effect as communicated to me as aforesaid I would have it
understood that what is considered to be novel and original and is therefore
claimed as the invention secured to me by the Letters Patent hereinabove in part
recited is;-
1. The use for treating sugar cane preparatory to its passage between juice
expressing rolls of preliminary rolls or cylinders arranged in pairs and caused to
rotate at a short distance apart at equal or different speeds, such rolls or cylinders
being provided at their circumferences with helical grooves and cutting edges to
split and disaggregate the canes substantially as described.
2. In apparatus such as referred to in claim 1 constructing the preliminary rolls
with grooves and cutting edges formed and arranged as above described with
reference to and represented in the accompanying drawing.
3. Causing the canes to enter between the preliminary rolls and to leave them in
the manner above specified.
4. Arranging preliminary crushing rolls such as above referred to directly in
front of the juice expressing mill and providing in connection therewith a feeding
device whereby the canes are fed to the said preliminary rolls and an inclined plane
or conveyor whereby they are conducted directly from the said rolls to the juice
expressing rolls or mill as above described.
5. The general arrangement of the combined apparatus as represented in the
accompanying drawings wherein each preliminary roll is provided with two sets of
helical grooves and cutting edges arranged in inverse directions and separated by a
partition or guide to maintain the longitudinal direction of the canes during their
passage through the apparatus substantially as described
In Witness whereof I the said William Lloyd Wise have hereunto set my
hand and seal this twenty third day of July in the year of our Lord one
thousand eight hundred and eighty three.
