I THOMAS WILLIAMS the Younger of 45 Myddelton Square in the County of
Middlesex Engineer do hereby declare the nature of said Invention for "IMPROVE-
MENTS IN SILENT MINCING MACHINES FOR CUTTING AND MIXING SAUSAGE
MEAT AND OTHER LIKE SUBSTANCES to be as follows:-
This Invention relates to certain improvements upon or additions to the class of
silent mincing machines wherein revolving knives mounted on a horizontal knife
shaft work in a horizontally revolving bowl, or machines of an analogous con*
struction, and has for its object the more effectual mixing or stirring of the meat or
other substance in the bowl whilst under the action of the rotary knives and
consists in the combination with the said class of machine of a rotary stirrer
situate in the revolving bowl and towards one side thereof and consisting of one
or more spiral bladed or other arms revolving horizontally and carried by a short
vertical spindle passing through and working in a suitable bearing formed either
in the rising plate or cover of the bowl or attached to a convenient part of the
framing of the machine and deriving its motion in either case direct from the knife
shaft by bevel gearing or by a worm on the knife shaft gearing into a worm wheel
on the upper end of the vertical spindle of the stirrer, the rotary horizontal knife
shaft and stirrer being thus coupled together and by the combined action of the
knives and stirrer on the meat or other substances producing a better and more
thorough cutting and mixing effect than has hitherto been obtained in the class of
silent mincing machines hereinbefore referred to.

Middlesex Engineer do hereby declare the nature of my said Invention for
"IMPROVEMENTS IN SILENT MINCING MACHINES FOR CUTTING AND MIXING
SAUSAGE MEAT AND OTHER LIKE SUBSTANCES" and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement thereof :-
--
My said Invention relates to certain improvements upon or additions to the class
of silent mincing machines wherein revolving knives mounted on a horizontal knife
shaft work in a horizontally revolving bowl or machines of an analogous con-
struction and has for its object the expediting the cutting of the meat or other
substance by effecting a more perfect mixing or stirring of the same in the bowl
whilst under the action of the rotary knives and consists in the combination
with the said class of machine of a rotary stirrer situate in the revolving bowl and
towards one side thereof and consisting of one or more screw bladed or other arms
revolving horizontally and carried by a short vertical spindle passing through and
working at its upper end in a suitable bearing mounted in the rising plate or other
cover of the bowl or in a bracket attached to any convenient part of the framing
of the machine. This stirrer derives its motion by preference in either case direct
from the knife shaft either by bevel gearing or which I prefer by a worm on the
knife shaft gearing into a worm wheel on the upper end of the vertical spindle of
the stirrer. The rotary horizontal knife shaft and stirrer thus work together and
by the combined action of the knives on the knife shaft and of the screw blades
on the short vertical spindle of the stirrer upon the meat or other substance in the
bowl a better and more thorough cutting and mixing effect is produced and the
cutting is more quickly effected than has hitherto been obtained in the class of
silent mincing machines hereinbefore referred to.
And in order that my said Invention may be fully understood I shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several Figures on the explanatory Sheet of Drawings hereunto annexed the
same letters of reference indicating corresponding parts in all the Figures.
Figure 1 of my Drawings is a transverse vertical section of so much of a silent
mincing machine of the class hereinbefore referred to as is necessary to illustrate
my present Invention.
Figure 2 is a corresponding plan of the same and
Figure 3 is a partial side elevation and vertical section of the upper part of the
machine looking from the left hand side of Figure 1.
a is the first motion shaft working in bearings b b carried on the standards c of
the machine and provided with the usual fast and loose driving pulleys & d' and
fly wheel e. This shaft carries also the usual knives or cutters which work in
the horizontally revolving bowl g. Rotary motion may be transmitted from the
shaft a to the vertical shaft h on which the bowl is mounted by a pulley and
strap i or otherwise through any suitable gearing which I have not considered it
necessary to illustrate in my Drawings. k is the short vertical spindle of the
rotary stirrer suspended at its upper end in bearings in a bracket arm m attached
to one of the standards. This short spindle extends nearly to the bottom of the
bowl and carries a series of curved arms or blades n which are caused to revolve at
a slow speed in the direction of the arrow inside the bowl near one side thereof
the spindle k being driven by preference from the knife shaft a by a worm o
gearing into a worm wheel p fast on the upper end of the spindle of the stirrer.

The spindle k with its curved stirring blades can be readily removed and replaced
at will without disturbing the shaft a by simply slackening the lever nut
slipping the bracket arm m carrying the said spindle from off its attaching screw
said arm being slotted for that purpose as shown more clearly in Figure 3.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is―
The combination with the revolving knives and rotary bowl of a silent mincing
machine of one or more horizontally revolving stirring arms or blades mounted on
a vertical spindle situate near one side of the bowl and driven by gearing from the
knife shaft substantially as and for the purpose herein before described and
illustrated by my Drawings.
