PROVISIONAL SPECIFICATION.
Improvements in the Construction of Machines for Cutting, Mincing,
and Mixing Meat and other substances.
I JOHN COPPARD of 21 New Charles Street, City Road, London E.C., in the
County of Middlesex, Engineer, do hereby declare the nature of this invention to
be as follows:—
I make a body or cylinder of wood iron or any suitable material, in manner
following the body or cylinder, I make of any circumference or length desired,
having a grove on each side of the inside at opposite angles.
One end of said body or cylinder is open, the opposite end is partly closed,
having a hole of suitable size in the centre, to receive end of spindle shaft, to
be described hereafter.
I
At the bottom side of body or cylinder, outside, between the groves, arrange
feet or standards, of suitable form, to support the aforesaid body or cylinder, as may
be desired.
At top side of cylinder, at the end partly closed I arrange a funnel shaped
opening through which the meat and other substances pass into the cylinder, and
passing through the cutters to be hereafter described, is forced out at open end of
cylinder, cut in small pieces as desired.
I now make a spindle shaft, of suitable form and size, one end being made to fit
the hole in the part closed end of cylinder, passes in at the open end of cylinder,
and through partly closed end of cylinder, a portion of shaft projecting beyond and
outside end of cylinder to aforesaid projecting end of spindle shaft 1 attach the
necessary gear to revolve the spindle shaft.
now make any suitable number of cutters of any desired substance, of steel
or any suitable metal, either forged or cast, sufficiently long to reach across the
inside of cylinder, the ends of said cutters entering the recesses of the groves
before refered to.
These cutters have a round hole in the centre, to allow the spindle shaft to
revolve therein, the cutter ends remaining stationary in the groves in the cylinder,
the edges of these cutters have cutting edges of suitable form thereon.
I now make another set of cutters as follows these cutters are made of steel or
other suitable metal, forged or cast, of sufficient lengths to revolve within the
cylinder, without their ends entering the groves in the cylinder. They are made
in any suitable form, and have cutting edges, the opposite of those above described,
and have square or other suitable shaped holes in their centre, of suitable and at
differant angles.
I then place one of the first described cutters on the spindle shaft, and now one
of the last described cutters, and repeat this till the shaft is filled with these cutters
to its end are secured by a screw.
These cutters being arranged according to the angle of the holes therein form
an arcmedian screw which being revolved by the outside gear passes through the
stationary cutters, with ends in the groves, and thus cuts the meat or other material,
forces it out at open end of cylinder or through a suitable funnel or plates as may
be desired.
In the funnel shaped opening at top of cylinder, before described, I arrange a
spindle or shaft, on which I arrange a suitable number of blades or paddles of
suitable form, one end of the spindle projecting outside the funnel shaped opening,

page_text: to which I attach a pulley or cog wheel thereon, and connect it with the gearing
driving the inner spindle shaft thus causing it to revolve and force the meat or
other materials placed in the funnel shaped opening into the body or cylinder,
and into direct contact with the cutters contained in the cylinder.
Dated this 20th day of May 1891.

and Mixing Meat and other substances.
1 JOHN COPPARD of 21 New Charles Street, City Road London E.C. in the
County of Middlesex 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 :-
I make a body of iron or any suitable material, in the form of a cylinder, with
suitable projections as hereafter described, in the manner following, the body or
cylinder I make of any suitable dimentions, having a grove on each side of the
inside at opposite angles.
One end of aforesaid body or cylinder is open Fig. 3, A. A. the opposite end has
a suitable opening to receive end of shaft Fig. 5. C. at the bottom side of cylinder
arrange supports H. Fig. 2.
At top side of cylinder I Fig. 11 arrange a funnell or hopper to receive the
meat or other substances passing into the cylinder Fig. 1 and through the
cutters D. D and e. e Fig. 4 is forced out at open end of cylinder Fig. 3, A. A I
now make a spindle or shaft Fig. 5. of suitable form, one end being made to fit
the partly closed end of cylinder J. Fig. 1. is passed in at the open end of
cylinder A. Fig. 3. and through J. Fig. 1. to end of aforesaid shaft I attach suitable
driveing gear.
I now make cutters or knives Fig. 6. D and Fig. 7. e. of steel or any suitable
metal forged cast or stamped D Fig. 6 being sufficiently long to enter the
groves A. A. Fig. 3 while e. Fig. 7 revolve within the cylinder the cutters D Fig. 6
having a round hole in centre, the shaft Fig. 5 revolves therein carrying the
cutters e Fig. 7. round with it. The edges coming in contact with those D. Fig. 6.
cutting thereby the materials placed within the cylinder Fig. 1 and by the arrange-
ment of the cutters Fig. 7. forces the materials when cut and mixed out at A. A.
Fig. 3.
In the hopper 1. Fig. 1 I arrange a second shaft to which attach any suitable
number of propellers K. K. Fig. 1. of suitable form one end of aforesaid. shaft
extending outside the hopper. I arrange a pulley or cog wheel thereon, and
connect it by any suitable means with the gear driving the inner shaft J Fig. 1
thus causing it to revolve and so force the materials placed in the hopper I. Fig. 2.
into the cylinder Fig. 1. and in direct contact with the cutters .D. Fig. 6 and
e Fig. 7.

page_text: Having now particularly described and ascertained the nature of iny said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1st. The particular construction of the cylinder as described with groves
Figs. 1-3.
2nd. The construction and arrangement of the cutters D. e. Figs. 6 and 7.
3rd. The arrangement of the feeding apparatus as described K. K. Figs. 1 and 2.
