Complete Specification Accepted, 23rd Feb., 1889
I, GEORGE FLETOHER, of Masson Works, Litchurch, in the county of Derby,
Engineer, do hereby declare the nature of this invention to be as follows:
This invention relates to improvements in three roller sugar cane mills.
In carrying out my invention I place the two top rollers in the same plane, and
secure them in the headstock by means of horizontally placed wrought iron bolts; the
lower roller is placed vertically under the front top roller and is held in the headstock
by vertical wrought iron bolts.
By this arrangement of the rollers in the headstock the strain between them is
entirely taken by the wrought iron bolts both in the case of the two horizontal rollers
and the two vertical rollers whereby the crushing power of the mill is greater than in
mills hitherto constructed and at the same time the risk of fracturing the headstock is
reduced to a minimum, and; as the canes pass upwards through the two horizontal
rollers, the juice falls freely by its own gravity and cannot be re-absorbed by the
megass, thereby considerably increasing the total extraction.
I form an arch in the bottom of the headstock so as to allow the lower roller to be
removed without having to take the mill to pieces as described in the Specification
of my former Patent No. 1542 of 1885.

I, GEORGE FLETOHER, of Masson Works, Litchurch, in the County of Derby,
Engineer, 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 relates to improvenients' in three-roller sugar. can mills.
In carrying out my invention, I place the two top rollers in the same horizontal
plane and secure them in the headstock by means of horizontally placed wrought iron
bolts; the lower roller is placed under the front top roller and is held in the head-
stock by vertical wrought iron bolts.
In the accompanying drawing
Figure 1 is a rear elevation, and
Figure 2 is an end elevation of a three. roller sugar cane mill constructed according
to my invention.
Figure 3 is a horizontal section on line A B of figure 2.
Similar letters in all the figures indicate similar parts:
- a, a, represent the headstock, and b, c and d are the three rollers of my
improved sugar cane mill, the rear top roller being placed in the same horizontal
plane and the bottom roller d in the same vertical plane as the front top roller c.
ee are the horizontally placed wrought iron-bolts which 1 employ to secure the two
top rollers b and c in the headstock a, a; the said bolts embrace the front of the
headstock a as shown clearly in figure 3 and are tightened up by means of nuts ƒ,ƒ
on their ends which are passed through the cap g of the headstock.
h, h.are the vertically placed wrought iron bolts serving to secure the lower roller d
in the headstock. These bolts receive cottars i, i, in their lower ends, and their
upper ends which pass through the cap k are provided with nuts j, j for tightening
them up.
By this arrangement of the rollers in the headstock, the strain between them
is entirely taken by the wrought iron bolts both in the case of the two rollers b and c
in the same horizontal plane and of the two rollers c and d in the same vertical
plane whereby the crushing power of the mill is greater than in mills hitherto
constructed and at the same the risk of fracturing the headstock is reduced to a
minimum, and, as the canes pass upwards between the two top rollers b and c the juice
falls freely by its own gravity and cannot be re-absorbed by the megass, thereby
considerably increasing the total extraction.
I find it advantageous to form an arch and provide a moveable piece B in the
bottom of the headstock for supporting the bottom roller trunnions C and bearings so

page_text: as to allow the lower roller d to be removed without having to take the mill to pieces
as described in the Specification of my former Patent No. 1542 of 1885.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The improvements in three-roller sugar cane mills hereinbefore described and
illustrated in the accompanying drawing.
