PROVISIONAL SPECIFICATION.
Improvements in Machines for Mincing and Chopping Meat.
We, JONATHAN BARNES, RICHARD WALTON KENYON, and WILLIAM HENRY
KENYON, all of Accrington, in the County of Lancaster, Machinists, do hereby
declare the nature of this invention to be as follows:-
This invention relates to that class of machine in which the meat is carried to
the cutter by a screw and where a perforated plate is used as an auxiliary
to cutting and mincing knives to reduce the material to the required degree of
fineness.
It consists in constructing the machine with the knives so placed that a cutter or
knife is affixed to the end of the screw or formed as part thereof and rotates with it
and a fixed blade or cutter placed in contact with it and then a second rotating
blade or cutter which rotates in contact with the perforated plate.
In carrying out the invention we construct the outer casing of any ordinary or
convenient form with a hopper to receive the meat and a barrel to contain the
forcing screw.
To the delivery end of the screw we affix or attach a blade or cutter to rotate
with the screw or form the same as part of the screw and in contact with this
rotating cutter we place a stationary cutter which is fixed or held by a groove in
the casting. The meat as it is delivered from the end of the screw is thus severed or
cut by the rotating cutter without first coming in contact with or encountering a
fixed blade or cutter past which it would have to be forced. A second rotating
cutter is placed between the fixed cutter and the perforated plate with its cutting
face against the perforated plate.
If desired another pair of cutters may be introduced but it will be understood
that the movable or rotating cutter in each instance precedes the fixed cutter in
conjunction with which it works.
The cutters and plate are preferably made so that either face can be used as the
cutting edge or so that it will not make any difference which side thereof is first
threaded onto the spindle.
The plate is prevented from rotating by a pin in a groove or slot and the parts
are held in position by a cup screwed or clamped on to the end of the barrel.
Dated this 3rd day of June 1892.

Improvements in Machines for Mincing and Chopping Meat.
We, JONATHAN BARNES, RICHARD WALTON KENYON, and WILLIAM HENRY
KENYON, all of Accrington, in the County of Lancaster, Machinists, 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 that class of mincing machine in which the meat is
carried through the machine from the hopper to the cutter by a screw and wherein
a perforated plate is used as an auxiliary to cutting and mincing knives to reduce
the material to the required degree of fineness.
It consists in constructing the machine with the knives so placed that a cutter or
knife is affixed to the end of the screw or formed as part thereof and rotates with
it and a stationary blade or cutter placed in contact with it and then a second

the meat is severed or cut before being forced past a stationary blade or cutter.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Longitudinal sectional elevation.
Fig. 2. Transverse sectional elevation on line - with cap G.removed.
Fig. 3. Elevation of rotating cutter D affixed by pin d to end of the forcing
screw.
Fig. 4. Elevation of stationary cutter E.
Fig. 5. Elevation of rotating cutter H.
Fig. 6. Elevation of stationary perforated plate F.
The outer casing A, the hopper B to receive the meat and the forcing screw C
are all constructed of any ordinary or convenient form.
To the delivery end of the screw C we affix or attach by a pin d or other means
a blade or cutter D to rotate with the screw or form the same as part of the screw.
In front of this rotating cutter D and in contact with it we place a stationary
cutter E which is fixed or held by a groove in the casing. The meat as it is
delivered from the end of the screw is thus severed or cut by the action. of the
rotating cutter D against the stationary cutter E before being forced forward past
the stationary blade or cutter to the perforated plate for a final cut. At the end
of the casing A is placed a perforated plate F held in position by a screw cap or
ring G and prevented rotating by a pin g and between the fixed cutter E and the
perforated plate F is placed a second rotating cutter H with its cutting face
working against the perforated plate.
If desired another pair of cutters may be introduced but it will be understood
that the movable or rotating cutter in each instance precedes the fixed cutter in
conjunction with which it works.
The cutters and plate are preferably made so that either face can be used as the
cutting edge or so that it will not make any difference which side thereof is first
threaded onto the spindle.
The meat is placed into the hopper B and carried along by the forcing screw C
to the first pair of cutters consisting of the rotating cutter D and the stationary
cutter E by which it is cut or divided before being. forced forward beyond the
stationary one of the two cutters and is then passed forward to the second rotating
cutter H by which it is further cut and minced as it enters the holes in the
perforated plate F.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we wish it to be understood
that we are well aware that perforated plates and rotating knives or cutters have
been used for mincing meat and we do not make any claim for such per se but we:
declare that what we claim is :-
1. In a mincing machine provided with forcing screw and perforated cutting
plate the combination of a rotating knife or cutter affixed to the end or forming
part of the forcing screw, rotating against a stationary knife or cutter by which
rotating knife the meat is severed or cut before being forced past the stationary
knife or cutter to the perforated plate substantially as described and shown.
2. A machine for mincing or chopping meat having the several parts constructed
and arranged together in combination substantially as and for the purpose described
and shown.
