1, CHARLES WILLIAMS GUY, of the firm of Guy, Deacon, & Co., Contractors and
Colonial & Consulting Engineers, of Nos. 59 & 60, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
This invention has reference to crushing mills suitable for expressing juice from
sugar canes, or for other analogous crushing purposes.
According to my invention the lower roller or rollers is or are suspended by means
of bolts provided at their lower ends with a cover or covers, the arrangement being
such that a line intermediate between the axes of the said suspending bolts parallel
therewith and passing through the centre of the main driving or upper roller will be
radial to that of the roller, and will pass through the axis of the suspended roller.
In constructing a crushing mill according to my invention with four rollers, there
may advantageously be two upper rollers and two lower rollers arranged, as I will
now describe, with a view to obtain a better extraction of juice than has heretofore
usually been obtained by means of sugar cane crushing mills having three horizontal
rollers. In this four roller mill the two upper rollers are in the same horizontal plane,
and are held together by through bolts with outside covers, and the lower rollers are
suspended radially to and with the main driving roller by bolts with closing covers
arranged at the under-side of the journals of the shafts of the lower rollers, so that
the rollers can be lowered and removed from the mill without disturbing the side
frames or cheeks. The one lower roller, (which for distinction I will call the second
crushing roller,) is suspended by through bolts passing through the upper frame at
two opposite sides of the shaft of the main driving roller.
Crushing mills may be constructed in accordance with my invention in various
forms, and the suspension of the rollers as described may be applied in mills of different
types.

Improvements in Orushing Mills.
I, CHARLES WILLIAMS GUY, of the Firm of Guy, Deacon, & Co., Contractors,
Colonial and Consulting Engineers, of Nos. 59 and 60, Chancery Lane, in the County
of Middlesex, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention has reference to crushing mills suitable for expressing juice from
sugar canes, or for other analogus crushing purposes.
According to my invention the lower roller or rollers is or are suspended by means
of bolts provided at their lower ends with a cover or covers, the arrangement being
such that a line intermediate between the axes of the said suspending bolts parallel
therewith and passing through the centre of the main driving or upper roller will be
radial to that roller, and will pass through the axis of the suspended roller.
In constructing a crushing mill according to my invention with four rollers, there
may advantageously be two upper rollers and two lower rollers arranged as I will
now describe, with a view to obtain a better extraction of juice than has heretofore
usually been obtained by means of sugar cane crushing mills having three horizontal
rollers. In this four roller mill the two upper rollers are in the same horizontal plane,
and are held together by through bolts with outside covers, and the lower rollers are
suspended radially to and with the main driving roller by bolts with closing covers
arranged at the underside of the journals of the shafts of the lower rollers, so that
the rollers can be lowered and removed from the mill without disturbing the side
frames or cheeks. The one lower roller (which for distinction I will call the second
crushing roller,) is suspended by through bolts passing through the upper frame at
two opposite sides of the shaft of the main driving roller.
Crushing mills may be constructed in accordance with my invention in various
forms, and the suspension of the rollers as described may be applied in mills of different
types.
The accompanying drawing illustrates in side elevation a four roller crushing mill
according to this invention, suitable for crushing sugar cane. 1 and 2 are two upper
rollers arranged with their axes in the same horizontal plane and held together by
two pairs of through bolts 3 provided with outside covers 4, each pair of such bolts
passing through one of the side frames 5 as shown. and 7 are two lower rollers
each suspended radially to and with the roller 1 which is the main driving roller.
The lower roller 6 is suspended by four pairs of through bolts 8 two pairs being
arranged at each journal of the roller 6, at each side of the mill. These bolts pass
through the side frames and are provided at their lower ends with closing covers or
plates 9 arranged to support bearings or brasses 10 at the underside of the journals
of the roller shaft 6*, the bolts of each pair being arranged at opposite sides of the
shaft of the roller 1 as shown. The other lower roller 7 is suspended by four pairs of
T-headed bolts 11, two pairs being arranged at each journal of the roller 7, at each

page_text: side of the mill; these bolts are inserted sideways into position in the frame, and are
provided with closing covers or plates 11 which support the bearings or brasses for
the journals of the roller shaft 7*. 12 and 13 are wedges by means of which wear of
the brasses of the rollers 2 and 7 respectively may be compensated for, and 14, 14,
are liner plates to allow of compensation for wear in the bearings of the roller 6.
15, 15, are trash turners to guide the crushed canes from roller 7 to roller 6 and from
roller 6 to roller 2 as shown. 16 is a pan or trough to catch juice flowing from
roller 7, when the mill is used as a sugar cane crushing mill, and guide such juice
into the foundation plate.
By arranging the rollers in the manner hereinbefore described and shown in the
drawing, a better extraction of juice can be obtained than has heretofore been usual
in sugar cane crushing mills, and the lower rollers 6 and 7 being suspended in the
manner described and shown can be loosened and removed from the mill without
disturbing the side frames or cheeks of the mill.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner it is to be performed, I declare that what I claim is :-
:-
1. In a crushing mill, the arrangement and suspension of the lower roller or rollers
radially to and ith the main driving roller by bolts substantially in the manner
described..
2. In a crushing mill suspending the lower roller or rollers radially to and with
the main driving roller by means of bolts provided with closing covers or plates
substantially as hereinbefore described.
3. My improved crushing mill with suspended rollers substantially as hereinbefore
described with reference to and shown in the drawing annexed.
