page_text: I, FREDERICK WILLIAM FOLLOWS, of Froxmer Street, Gorton, in the County of
Lancaster, Agricultural Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention is designed to increase the efficiency or cutting properties
machines in which meat is minced either by the action of a knife or knives
rotating against a perforated plate or of knives or blades rotating against fixed or
stationary knives or blades and to provide means for adjusting the knife and
perforated plate.
In a machine in which a perforated cutting plate is used I place a knife to rotate
against the outside of the plate and a scraper or its equivalent to rotate against the
inside of the plate. The end of the screw or scroll is formed with a projecting
stud or spindle forming an elongation thereof which passes through the centre of
the perforated plate. At the end this is formed with a flat or its equivalent to
drive the knife and a screw is inserted in the end to hold the knife in position.
The adjustment of the knife is accomplished from the front end of the machine by
means of the screw screwed into the projecting end of the forcing screw or scroll.
The perforated steel plate is held in position by a stud or screw in the side of the
casing by which it is prevented rotating the plate being notched on the periphery
to suit. The scraper or its equivalent which rotates against the inner face of the
plate is threaded onto the stud or projecting part of the screw and is held in position
by a pin or projection on the back thereof which engages with a recess in the end
of the forcing screw or the pin may be affixed to the screw and the scraper or
knife be provided with a hole, recess or notch.
At the hopper end of the machine I place a stationary ledge or knife or its
equivalent cast on the bottom of the hopper and ground or turned to a sharp edge.
The forward or cutting edge of the forcing screw or scroll is ground so as to cut
in contact with the edge formed on the body of the machine. A shearing action
similar to that of scissors takes place cutting the meat as it enters the machine.
This may be applied either to machines constructed with a perforated plate at
the delivery end or to machines in which the meat is cut or reduced to the desired
degree by knives in the form of a forcing screw or cut therein acting against
stationary knives set in the casing.

I, FREDERICK WILLIAM FOLLOWS, of Froxmer Street, Gorton, in the County
of Lancaster, Agricultural Engineer, 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 is designed to increase the efficiency or cutting properties of
machines in which meat is minced either by the action of a knife or knives rotating
against a perforated plate or of knives or blades rotating against fixed or stationary
knives or blades and to provide means for adjusting the knife and perforated plate.
It consists essentially in constructing the end of the screw (where a perforated
plate and rotating cutting knife are employed) with a projecting stud or spindle
forming an elongation passing through the perforated plate and upon which the
knife is placed with a screw inserted in the end to adjust the position of the knife
and the pressure against the perforated plate, and also in providing a stationary
cutting ledge or knife around the bottom edge of the hopper against which the
edge of the forcing screw cuts or shears the meat as it enters the barrel of the
machine.
The invention will be fully described with reference to the accompanying
drawings.
Fig. 1. Longitudinal section of machine with perforated cutting plate and
rotating knife.
Fig. 2. End elevation of same.
Fig. 3. Longitudinal section of machine with fixed cutting blades and rotating
cutters.
Fig. 4. Transverse section of same with screw removed.
Fig. 5. Plan from below of the upper part of the casing.
Referring to Figs. 1 and 2 showing a machine in which a perforated cutting
plate B is used, a knife C is placed to rotate against the outside of the perforated
plate B and a scraper D or its equivalent to rotate against the inside of the plate.
I form the end of the forcing screw E with a projecting stud or spindle e forming
an elongation thereof which passes through the centre of the perforated plate B.
At the end the spindle e is provided with a key or is formed with a flat or its
equivalent to drive the knife and a screw F is inserted in the end to hold the
knife C in position. The adjustment of the knife C is accomplished from the front
end of the machine by means of the screw F screwed into the projecting end e of
the forcing screw or scroll E. The perforated steel plate B is held in position by
a nut or screwed cap G which screws over the end of the casing A and is prevented
rotating by a key or pin fitting into the notch b in the side of the plate. The
scraper D or its equivalent which rotates against the inner face of the perforated
plate B is threaded onto the stud or projecting part e of the screw E and is held
in position by a pin or projection on the back thereof which engages with a recess
in the end of the forcing screw or by a pin affixed to the screw fitting into a slot or
not in the scraper or knife D.
Referring to Figs. 3, 4 and 5 showing a machine constructed with fixed and
rotating cutters I place a stationary ledge or knife K or its equivalent cast on the
bottom edge of the hopper or opening through which the meat is introduced and
ground or turned to a sharp edge. The forward or cutting edge of the forcing
screw E is ground so as to cut in contact with the edge K formed on the body A
of the machine. A shearing action similar to that of scissors takes place cutting
the meat as it enters the machine.
This cutting ledge K may be applied either to machines constructed with a
perforated plate at the delivery eul such as shown in Fig. 1 or to machines in which

page_text: the meat is cut or reduced to the desired degree by knives in the form of a forcing
screw or cut therein acting against stationary knives set in the casing as 10
Figs. 3 to 5.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A mincing machine constructed with the end of the forcing screw in the form
of a stud projecting through the perforated cutting plate, with a scraper threaded
thereon on the inside of the plate and a cutting knife on the outside of the plate
and a screw inserted in the end of the projecting end to regulate the position of
and pressure upon the knife substantially as described.
2. A mincing machine constructed with a cutting ledge around the underside of
the opening in the casing through which the meat is introduced substantially as
described.
