three rollers, in use all over the world, has remained in design the same 
as originally introduced (by whom we have no record). By this 
reference I allude, that the three rollers have always been arranged 
horizontally and tri-angularly, if we except vertical mills usually applied 
to windmills, and it remains an unaccountable fact, this design remains 
to this day as the best type of Mill in use. 
The model before you is a departure from this type of mill and is 
designed with the view of adding additional strength to the mill and 
securing a higher extraction of juice from the cane. 
The altered position of the rollers allows of a better arrangement 
of wrought iron bolts, in lieu of cast iron standards for carrying the 
enormous and irregular strains that sugar mills are subjected to. 
In describing this mill I will divide same under two heads. Firstly, 
additional strength in construction as compared with ordinary mills in 
general use ; and secondly, increased extraction of cane juice. 
Firstly, additional strength in construction — By an inspection of the 
drawing, same being an exact representation of the Model Mill, you will 
observe that the cane or front roller, B Fig. i, is placed vertically and 
under the top roller A.. The position of these two rollers enables the 
strains to be carried entirely and directly through the two gland bolts 
CC, relieving the cast iron Mill cheek or headstock of all the strains 
that exists in the present triangular-mills in general use. The final 
crushing roller D is placed horizontally and in the same plane as the 
top roller A ; the position of these two rollers enables same to be 
secured into position by the wrought iron strap bolts seen on plan Fig. 
2 at EE and in Fig. 3 end elevation at FFFF. This arrangement 
makes a very strong connection, the strain being carried entirely by the 
wrought iron strap bolts FFFF and relieving the mill cheeks of all 
strain. Practical engineers are aware that a fractured headstock is 
made practically good by being strapped usually one strap to each 
cheek. By the application in the design of two straps to each head- 
stock same being in the first instance in sound condition must add 
additional strength which I think will hardly be denied. Having 
conclusively proved to you by the foregoing that all the strains of the 
improved mill are taken up by the four gland bolts CCCC and the 
eight strap bolts FFFFFFFF the mill cheek becomes a standard only, 
for carrying the weight of three rollers, and keeping them centrally 
correct. If we accept the mechanical arrangement of the mill to be 
correct as I have described it, and that all the strains are carried through
