Improvements in Sugar Cane Mills.
I, ALEXANDER HENRY REED, of 64 Mark Lane in the City of London,
Engineer, do hereby declare the nature of the said invention to be as follows:-
The first improvement consists in the particular arrangement of the auxiliary or
additional bagass carrier, which will enable ordinary sugar cane mills placed one
before the other (the first being intended to crush the cane, and the second to
compress the bagass supplied by the first), to work separately, one or the other, or
both at once, at the process of cane crushing. The advantage resulting from this
arrangement is that the work of cane crushing continues in case one or other of the
two mills should be stopped from any cause.
The second improvement consists in causing water or other cold liquid to
circulate inside the bearings of the journals of the shafts of the machines, and
especially in those of the journals of the crushing cylinders, in order to keep them
at a low temperature by constant contact with a cold body. This improvement
prevents the heating of the said parts caused by the enormous pressure of the one
against the other, vic. of the journals against the bearing, thus avoiding deteriora-
tion and consequent stoppage for repairs.
Fig. 1 of the accompanying drawings shows as a diagram, a side view of the
arrangement in general use in cane mills, for first crushing the cane and then com-
pressing the bagass; but in order to make the invention clearly understood, the
improved arrangement forming the object of this application for Patent is shown in
dotted lines.
Fig. 2 is a plan of the same.
In the arrangement in general use, the cane deposited on the carrier A, Figs. 1
and 2 passes through the first mill B, from thence the bagass is discharged by the
usual inclined plane upon the carrier C which conveys it to the second mill D,
which compresses it and forces it out by an inclined plane or other suitable
ineans.
In
According to this invention the cane, after passing through the first mill B is
discharged laterally upon the auxiliary or additional carrier S which conveys it
outside. This lateral discharge may be effected by any suitable means, by an
endless screw conveyor for instance, or by any suitable conveyor or carrier.
the accompanying drawings I have shown as a simple arrangement one side K
and K of the inclined plane, diagonally superposable upon the ordinary inclined
plane in order to discharge the bagass upon the auxiliary lateral carrier S forming
the principal object of this improvement and by which, in this manner, the two
mills B and D are made independent of each other, inasmuch as by this means,
cane instead of bagass may be placed directly upon the carrier C, the bagass being
discharged laterally. Consequently, should one of the two mills be stopped for
any reason, the work may be continued by the other; on the other hand, should
there be an unusual quantity of cane to be crushed, by placing it directly upon the
carriers A and C, each mill may be employed for the purpose.
In the contrary case, by turning off or leaving out the side of the diagonally
superposable inclined plane K and K', the bagass produced by the first mill B will
be discharged upon the carrier C to be carried for compression to the mill D as
above described.
The second improvement is represented in Fig. III, which shows a side view of
the bearing M taken between the journal T of any axis, but especially that of a
crushing cylinder, and the cap H of any pedestal.

page_text: Fig. IV is a plan of the bearing M. This bearing is hollow and may form one
chamber or several compartments of any suitable shape; it has not been thought
necessary to show such chamber or compartments in order to leave the drawing
more clear.
Water or any other suitable cold liquid is continually passed through
it by one or more orifices, as for instance L inlet, V outlet; such liquid passing
continually through, will carry off much heat, and thus lower the temperature of
the bearing, whose tendency is to become heated by friction.
.
The liquid may be conveyed into, and discharged from the machine by any
suitable means.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. In sugar cane mills, the combination with the inclined plane generally used
to convey bagass, of an additional or auxiliary diagonally superposable inclined
plane substantially as and for the purpose above described.
2. In sugar cane mills, the hollow bearing above described, constructed to receive
a continuous current of cold liquid substantially as above described:
