PROVISIONAL SPECIFICATION.
Improvements in Mincing Machines.
We, DAVID DICKSON of 3 Thurnybank, Edinburgh, Engineer and JOHN
RODERICK WILSON of 77 Craiglea Drive, Edinburgh; Engineer and Shop-
outfitter, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for mincing meat and such like and it has for
its object to improve the construction of such machines.
Butchers mincing machines, as at present usually constructed, are driven by
means of toothed wheels which mesh with one another. This arrangement of
driving gear is found to have some disadvantages.
Under our invention we construct the machine with the usual rotary cutters or
mincers but we drive them by means of a fly wheel and chain gearing, instead of
the usual toothed gear.
There is fitted on or to the machine at any suitable part a short shaft which has
on it a pinion wheel and also a fly wheel with driving handle or crank. The pinion
wheel is made with teeth suitable for chain gearing. The driving chain after being
fitted on the pinion passes to a chain wheel fitted on the axle of the cutters of
the machine. By revolving the fly wheel the cutters are at once put in rapid
motion.
The chain gearing, as described, affords greater safety to the worker and also
requires less labour to drive than the usual arrangements.

COMPLETE SPECIFICATION.
Improvements in Mincing Machines.
We, DAVID DICKSON of 3 Thurnybank, Edinburgh, Engineer, and JOHN
RODERICK WILSON, of 77 Craiglea Drive, Edinburgh, Engineer and Shop
Outfitter, 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 machines for mincing meat and such like and it has for
its object to improve the construction of such machines.
Butchers' mincing machines, as at present usually constructed, are driven by
means of toothed wheels which mesh with one another. This arrangement of
driving gear is found to have some disadvantages.
Under our invention we construct the machines with the usual rotary cutters or
mincers but we drive them by means of a fly wheel and chain gearing, instead of the
usual toothed gear.
There is fitted on or to the machine at any suitable part a short shaft which has
on it a pinion wheel and also a fly wheel with driving handle or crank. The pinion
wheel is made with teeth suitable for chain gearing. The driving chain after being
fitted on the pinion passes to a chain wheel fitted on the axle of the cutters of
the machine. By revolving the fly wheel the cutters are at once put in rapid
motion.
And in order that our said invention may be properly understood we have
hereunto appended an explanatory sheet of drawings, whereon:-
Fig. 1 is a part side elevation of a mincing machine with our improved driving
gear.

page_text: Fig. 2 is a end elevation of the machine.
Referring to the drawings:-
--
a is a short shaft or pivot which is carried in the base plate of the machine or at
other suitable part. Carried on the shaft is a sleeve b having a pinion c and a fly
wheel on it. The fly wheel is provided with a driving handle e. From the
pinion c, a driving chain / passes round a chain wheel g fitted on axle h of the
cutters or mincers of the machine.
By turning the handle e the cutters or mincers are put in rapid motion.
The chain gearing, as described, affords greater safety to the worker and also
requires less labour to drive than the usual arrangements.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what
we claim is :-
A mincing machine constructed and operated substantially as hereinbefore
described with reference to 'the drawings annexed.
