page_text: I, GEORGE FLETCHER, of Masson and Atlas Works, Litchurch, Derby, in the
County of Derby, Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in machines for breaking sugar and other
substances and has for its object to provide a more efficient machine than those
now generally used.
According to my invention I mount in suitable standards a number of shafts on
which are keyed a number of discs having sharply pointed teeth, the said discs
being arranged so as to form toothed rollers. These toothed rollers are preferably
of different diameters and I so arrange them that the sugar or other substance
to be broken, fed to the machine through a suitable hopper, is subjected to a
graduated series of breaking operations.
The bearings of some or all of the rollers are provided with means such as a
screw or eccentric whereby the distances between adjacent rollers can be diminished
or increased to suit the substances to be broken.
In practice I find it advantageous to drive all my rollers from one shaft through
the medium of suitable gearing although I may drive the shafts independently.

I, GEORGE FLETCHER, of Masson and Atlas Works, Litchurch, Derby, in the
County of Derby, Engineer, do hereby declare the nature of this invention and in
[Price 8d.]

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to improvements in machines for breaking sugar and other
substances and has for its object to provide a more efficient machine than those
now generally used.
According to my invention I mount in suitable standards a number of shafts on
which are keyed a number of dises having sharply pointed teeth, the said dises
being arranged so as to form toothed rollers. These toothed rollers are preferably
of different diameters and I so arrange them that the sugar or other substance
to be broken, fed to the machine through a suitable hopper, is subjected to a
graduated series of breaking operations.
The bearings of some or all of the rollers are provided with means such as a
screw or eccentric whereby the distance between adjacent rollers can be diminished
or increased to suit the substances to be broken.
In practice I find it advantageous to drive all the rollers from one shaft through
the medium of suitable gearing although I may drive the shafts independently.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which :-
Figure 1 is a sectional end elevation of a machine for breaking sugar and other
substances constructed according to my invention:
Figure 2 is a sectional side elevation of the same.
a, are the standards of the machine and b, b, c, d, d¹ the shafts which are
mounted in bearings e, e in the said standards. f, f are the dises provided with
sharply pointed tooth g, g and arranged upon the shafts b, b, c, d, d in such a
manner as to form toothed rollers as clearly seen on reference to figure 1 of the
drawing.
In the drawing I have shewn five rollers, namely, two upper rollers those on
the shafts b, arranged one on each side of the machine, one central roller on the
shaft e mounted beneath the two upper rollers, and two smaller rollers on the
shafts d and d' mounted on one side of the machine.
All these rollers are driven from the shaft h which is rotated by means of a belt
running upon the fast and loose pulleys i, s, the motion of the said shaft being
transmitted by the spur wheels and pinions A to the different rollers which are
rotated in the directions indicated by the arrows shewn in figure 2.
jis the hopper from which the material to be broken is fed between the two
uppermost rollers b, 6, the material then passing between the roller on the shaft b
and the central roller and finally between the two smaller rollers on the shafts d
and d.
To enable the distances between the pairs of rollers, between which the material
to be broken is passed to be regulated I provide for adjusting the bearings of the
rollers. In the drawing the roller on the shaft & and the central roller are
mounted in bearings which can be adjusted in position by screws k, k operated
from outside the machine by a key or spanner. In the case of the central roller
the screw is rotated by a spindle through the medium of bevel gear m, the
spindle being operated by a key or spanner.
In the case of the lowermost rollers the means I employ consist in mounting the
roller on the shaft d upon arms n, n which are held upon eccentrics o operated by
a lever or handle o', the said lever or handle of being provided with a pin p or the
like adapted to enter holes q, q formed in the standard a so as to secure the roller
in different positions and thus regulate the distance between the two lowermost
rollers.
With this arrangement of machine it will be obvious that large pieces of the
substance to be broken can be reduced to medium sized pieces or into very small
fragments as may be required and it will also be obvious that by suitably adjusting
the rollers the substance may be gradually broken in a series of operations thus
avoiding or considerably diminishing any excessive strains upon the working
parts of the machine.

page_text: 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 combination and arrangement of parts forming the improved machine for
breaking sugar and other substances herein before described and illustrated in the
accompanying drawing.
