PROVISIONAL SPECIFICATION.
Improvements in Three Roller Mills for Crushing Cane, and for
like purposes.
1, GEORGE FLETCHER, of Masson and Atlas Works, Litchurch, Derby, in the
County of Derby, Engineer, do hereby declare the nature of this invention (partly
a communication to me by George Brocklehurst, of the Island of Barbados, West
Indics, Engineer) to be as follows:-
This invention relates to improvements in three roller mills for crushing cane
and for like purposes, and has for object an improved construction of the same
whereby the lower rollers can be brought nearer together than in mills of ordinary
construction and the strains occasioned by the crushing of sugar canes, for example,
are exerted practically parallel to the bolts securing the side caps-to the standards,
thereby relieving the latter from strain and avoiding breakage.
According to my invention I secure the top cap to each standard by one or
more fork-shaped gland bolts, the two prongs of the same passing through the top
cap and the upper part of the standard and uniting into a single bolt just under
the top roller and above the two lower rollers, which single bolt passes through the
lower part of the standard and is secured in the ordinary manner.
The forked gland bolt or bolts can be made in one piece or built up of several
parts.

Improvements in Three Roller Mills for Crushing Cane, and for
like purposes.
I, GEORGE FLETCHER, of Masson and Atlas Works, Litchurch, Derby, in the
County of Derby, Engineer, do hereby declare the nature of this invention (partly
a communication to me by George Brocklehurst, of the Island of Barbados, West
Indies, Engineer) 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 improvements in three roller mills for crushing cane
and for like purposes, and has for object an improved construction of the same
whereby the lower rollers can be brought nearer together than in mills of ordinary
construction and the strains occasioned by the crushing of sugar canes, for example,
are exerted practically parallel to the bolts securing the top caps to the standards,
thereby relieving the latter from strain and avoiding breakage.
According to my invention I secure the top cap to each standard by one or more
fork-shaped gland bolts, the two prongs of the same passing through the top cap
and the upper part of the standard and uniting into a single bolt just under the
top roller and above the two lower rollers, which single bolt passes through the
lower part of the standard and is secured in the ordinary manner.

page_text: The forked gland bolt or bolts can be made in one piece or built up of several
parts.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawings, in which
:―
Figures 1, 2, 3, 4 and 5 are vertical sections of three roller sugar cane mills
constructed according to my invention.
Similar letters of reference indicate the same or corresponding parts in all the
figures.
a is one of the standards of the mill, & the top roller and c, d the lower rollers.
These rollers are of ordinary construction and are mounted in bearings e in the
standards a in the ordinary manner.
are the side caps, and y, are the bolts securing them to the standards a.
is the top cap, and is the single holt of my fork-shaped gland bolt (I may
employ any suitable number of these fork-shaped gland bolts) the said bolt dividing
into two prongs j, just under the top roller and above the two lower rollers,
which prongs pass, as shewn, on either side of the top roller through the upper
part of the standard a and the top cap and are secured by nuts in the usual
manner.
In Figures 1, 2 and 3 the gland bolt is shown in one piece but in Figures 4 and 5
it is shown built up of two or more parts.
In Figure 4 the prongs j, j are made in one piece and the bolt is screwed or
otherwise secured into the same.
In Figure 5 the prongs j, j are separate from one another and from the bolt i
and have their lower ends, turned inwards. The bolt i is provided at its
upper end with Interal projections, which rest on the inwardly bent ends ƒ, j'
of the prongs j. j.
As above mentioned by this construction of gland bolt, the lower rollers can be
brought very close together whereby the trash turner can be made correspondingly
narrow or can even be entirely dispensed with.
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 :-
1. In a three roller mill for crushing cane and for like purposes, securing the
caps of the top roller to the standards by means of one or more fork-shaped gland
bolts, substantially as described.
2. The improved three roller mills for crushing cane and for like purposes
herein before described and illustrated in Figures 1, 2, 3, 4 and 5 respectively.
