Heretofore the frames of sugar cane mills have usually been made of cast iron
Now, according to the present invention they are. constructed of wrought iron,
or of iron and steel, in such a manner as to realise certain advantages not attainable
with the ordinary cast iron construction. Thus, in a mill according to this
invention a cane or trash guide of less than the usual width can be used, thereby
reducing the friction resulting from the passage of cane through the apparatus, this
cane or trash guide is capable of adjustment whilst the mill is working. Moreover
the frame, whilst of less weight than with the ordinary construction, is stronger,
and affords special facilities for erection, transport and maintainance.
The same mode of construction can be applied in the frames of the transmission
gear and motor.
An important feature of the improved construction is that it allows of diminishing
the distance apart of the two bottom rolls, or, in other words, the angle formed
by straight lines uniting the axes of these rolls to the axis of the top roll.-there
results a corresponding reduction in the width of the cane or trash guide, and
consequently in the period of time during which the partly crushed cane or trash
has to slide over a fixed surface that opposes its advance.
With the ordinary cast iron construction this result could be attained only in a
slight degree as the bolts that resist the lifting effort of the top roll would be cut

page_text: by the recesses that receive the axes of the bottom cylinders; moreover cast iron
could not be relied on to resist the great strain.
The cane or trash guide is able to slide in grooves and is provided with rods or
connections that can be operated by bolts and nuts.
The girder supporting the cane or trash guide is carried by two brackets; and
between these brackets and the girder are arranged wedges so that the height of
the trash guide can be adjusted. Thus there is provision for both horizontal and
vertical adjustment of the cane or trash guide, without its being necessary to stop
the mill.
The caps of the roll bearings are constructed in the form of hollow girders which
facilitates their construction of the requisite strength, and also the fitting of the
bolts and lubricators.
The frames are arranged so as to allow of the removal of the bottom rolls
without raising by simply rolling them on wooden blocks that may be readily
arranged underneath Each bottom bearing is free in its recess, and bears against
a set screw adjustable at will. The bearing caps are secured by means of bolts
passing through the frames in such a way as to obviate liability to breakage of the
bolts through unequal working.
In carrying out the invention two vertical frames are used to support the rolls,
and are connected together by two hollow stays constructed in the form of hollow
beams or girders.-the lower part of the free space between these two frames is
occupied by a plate iron trough designed to receive the juice expressed by
the rolls.
Each frame consists essentially of two uprights of plate iron edged with angle
iron and united by iron plates which extend round the uprights and are rivetted
to the angle irons.
These frames are formed with recesses at their upper and lateral parts for the
reception of the bearings of the axes of the rolls. The vertical thrust against the
top roll is sustained by two bolts screwed or keyed into a steel collar rivetted
between the plates of the frame and enclosing the bearings of that roll.
Similarly, the horizontal thrusts against the lower rolls are sustained by four
bolts passing through the main frames and through the beam-like caps of the
bearings of those rolls. The vertical thrusts against the bottom rolls are sustained
by the wrought iron framing
Between the two main frames is the wrought iron girder supporting the trash
guide, and itself carried at its ends by brackets.
In order to bring the cane or trash turner nearer the roll as already mentioned
there is adapted to each of its ends a screwed rod which may be more or less
actuated by means of a nut held in a socket fixed in the bearing cap or frame of
the corresponding roll bearing.

"IMPROVEMENTS IN MACHINERY OR APPARATUS EMPLOYED TO EXPRESS JUICE
FROM SUGAR CANE (A communication from La Société Anonyme des anciens

""
Heretofore the frames of sugar cane mills have usually been made of cast iron.
Now according to the present invention, they are constructed of wrought iron,
or of iron and steel, in such a manner as to realise certain advantages not attainable
with the ordinary cast iron construction. Thus in a mill according to this
invention a cane or trash guide of less than the usual width can be used, thereby
reducing the friction resulting from the passage of cane through the apparatus;
this cane or trash guide is capable of adjustment whilst the mill is working.
Moreover the frame, whilst of less weight than with the ordinary construction, is
stronger, and affords special facilities for erection, transport and maintenance.
The same mode of construction can be applied in the frames of the transmission
gear and motor.
An important feature of the improved construction is that it allows of diminishing
the distance apart of the two bottom rolls, or, in other words, the angle formed by
straight lines uniting the axes of these rolls to the axis of the top roll, there results
a corresponding reduction in the width of the cane or trash guide and consequently
in the period of time during which the partly crushed cane or trash has to slide
over a fixed surface that opposes its advance.
With the ordinary cast iron construction this result could be attained only in a
slight degree as the bolts that resist the lifting effort of the top roll would be cut
by the recesses that receive the axes of the bottom cylinders; moreover cast iron
could not be relied on to resist the great strain.
The cane or trash guide is able to slide in grooves and is provided with rods or
connections that can be operated by bolts and nuts.
The girder supporting the cane or trash guide is carried by two brackets and
between these brackets and the girder are arranged wedges so that the height of
the trash guide can be adjusted. Thus there is provision for both horizontal and
vertical adjustment of the cane or trash guide, without its being necessary to stop
the mill.
The caps of the roll bearings are constructed in the form of hollow girders
which facilitates their construction of the requisite strength, and also the fitting
of the bolts and lubricators.
The frames are arranged so as to allow of the removal of the bottom rolls
without raising by simply rolling them on wooden blocks that may be readily
arranged underneath. Each bottom bearing is free in its recess and bears against
a set screw adjusted at will. The bearing caps are secured by means of bolts
passing through the frames in such a way as to obviate liability to breakage of
the bolts through unequal working.
A sugar cane mill frame constructed according to this invention is represented
on the accompanying sheet of drawings Fig 1 being an elevation partly in section,
and Fig 2 a half longitudinal section through the centre.
Two vertical frames A A support the rolls B B B and are connected together by
two hollow stays C C constructed in the form of hollow beams or girders,―the
lower part of the free space between these two frames is occupied by a plate iron
trough designed to receive the juice expressed by the rolls B.

page_text: Each frame A consists essentially of two uprights of plate iron edged with angle
iron and united by iron plates which extend round the uprights and are rivetted
to the angle irons.
The frames A are formed with recesses at their upper and lateral parts for the
reception of the bearings of the axes of the rolls B. The vertical thrust against
the top roll is sustained at each end by two bolts F screwed or keyed into a steel
collar G rivetted between the plates of the frame and enclosing the bearing of
that roll.
Similarly, the horizontal thrusts against the lower rolls are sustained by four
screw bolts I passing through the main frames and through the beam like caps H
of the bearings of those rolls. The vertical thrusts against the bottom rolls are
sustained by the wrought iron framing.
Between the two main frames A is the wrought iron girder I supporting the
trash guide, and itself carried at its ends by brackets P.
In order to bring the cane or trash guide or turner K nearer the roll as already
mentioned there is adapted to each of its ends a rod M with screwed end which
may be more or less actuated by means of a nut N held in a socket fixed in the
bearing cap or frame H of the corresponding roll bearing. By this arrangement
the adjustment of the cane or trash turner K may be effected without its being
necessary to stop the mill.
As shown the bottom plate D and gutter are also formed of plate and angle
iron but otherwise present no special peculiarity. From the description given
above the construction and arrangement of the frame work for the motor and
transmission gear will be readily understood, therefore it has not been deemed
necessary to give separate drawings of the same.
Having described the nature of the said invention and in what manner the
same is to be performed as communicated to me as aforesaid I would have it
understood that what is considered to be novel and original and is therefore
claimed in machinery or apparatus employed to express juice from sugar cane is,-
(1) The construction of the frames of wrought iron or wrought iron and steel,
(2) the arrangement whereby vertical and horizontal adjustment of the trash guide
is provided for, (3) the arrangements for sustaining the thrust of the rolls: all
substantially as described and shewn.
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.
