Improvements in Mincing Machines.
I FREDERICK RYLAND, of Houghton Street, West Bromwich in the County
of Stafford Ironfounder do hereby declare the nature of this invention to be as
follows:-
My invention has reference to machines for mincing meat and vegetables and for
other like purposes and consists of the improvements hereinafter described whereby
the mincing is more readily effected than in mincing machines of the ordinary
construction. Mincing machines constructed according to iny invention are worked
with less expenditure of motive power than ordinary mincing machines.

I arrange the parts of the machine generally as in ordinary mincing machines
but modify and construct certain parts in the ways hereinafter described.
employ the ordinary rotating shaft carrying the feeding screw to which two
cutters are affixed which cutters rotate with the said shaft. Between the two
rotating cutters is a fixed cutter consisting of a disc having perforations through
which the material to be minced is forced by the screw feeder. The said fixed
perforated cutter is usually made of a steel disc in which circular holes are drilled
or cast. The unperforated portions of the disc offer great resistance to the advance
of the material to be minced and in order to reduce this resistance to a minimum
I make the said fixed perforated cutter in the following ways. I take a series of
strips of hard steel so cut that they form when arranged at a right angle
or other
angle, a grating around which I cast a ring or frame by which the said strips are
fixed together in position. Or I make the said grating in one piece by the casting
process. I grind or polish both sides of the said grating so that the edges of the
crossing bars constitute fixed cutting edges against which the edges of the rotating
cutters work. The first rotating cutter in conjunction with the first cutting edges
of the fixed cutter slices or divides the material operated upon before it is forced
through the perforations in the fixed cutter, and tendons, cartilage and other hard
parts of the material operated upon in consequence of their division offer but little
resistance as they are pressed through the openings in the fixed cutter.
material thus sliced is pressed by the feeder through the openings in the fixed
cutter the fixed edges of which openings together with the second cutter rotating
on the outside of the fixed cutter complete the mincing of the material under
operation.
The
Mincing machines made according to my invention readily mince suet and other
materials which can only be imperfectly minced by mincing machines of the
ordinary construction.
Mincing machines made according to my invention may either be used alone or
combined with other machines such for example as sausage making machines.

I FREDERICK RYLAND, of Houghton Street, West Bromwich in the County
of Stafford Ironfounder, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention has reference to machines for mincing meat and vegetables and
for other like purposes; and consists of the improvements hereinafter described
whereby the mincing is more readily effected than in mincing machines of the
ordinary construction. Mincing machines constructed according to my invention
are worked with less expenditure of motive power than ordinary mincing machines.
I arrange the parts of the machine generally as in ordinary mincing machines
but modify and construct certain parts in the ways hereinafter described. I employ
the ordinary rotating shaft carrying the feeding screw to which two cutters are
affixed which cutters rotate with the said shaft. Between the two rotating cutters
is a fixed cutter consisting of a disc having perforations through which the material
to be minced is forced by the screw feeder. The said fixed perforated cutter is
usually made of a steel or cast metal disc in which circular holes are drilled or
cast. The unperforated portions of the disc offer great resistance to the advance
of the material to be minced and in order to reduce this resistance to a minimum
I make the said fixed perforated cutter in the following ways. I take a series of
strips of bard steel so cut that they form when arranged at a right angle or other
angle, a grating around which I cast or otherwise fix a ring or frame by which
the said strips are fixed together in position. Or I make the said grating in one
piece by the casting process. I grind or polish both sides of the said grating so
that the edges of the crossing bars constitute fixed cutting edges against which the
edges of the rotating cutters work. The first rotating cutter in conjunction with
the first cutting edges of the fixed cutter slices or divides the material operated
upon before it is forced through the perforations in the fixed cutter, and tendons,
cartilage and other hard parts of the material operated upon in consequence of
their division offer but little resistance as they are pressed through the openings in
the fixed cutter. The material thus sliced is pressed by the feeder through the
openings in the fixed cutter, the fixed edges of which openings together with the
second cutter rotating on the outside of the fixed cutter, complete the mincing of
the material under operation.
Figure 1 of the accompanying drawings represents in front elevation and
Figure 2 in vertical section (partly in front elevation) a mincing machine containing
my improvements.
Figure 3 represents in vertical section a portion of the barrel or cylinder and
parts connected therewith diawn to a larger scale than Figures 1 and 2:
Figure 4 represents in front and end elevation a portion of the feeding screw of
the machine and Figures 5 and 6 represent respectively the inner and outer
rotating cutters of the same :
Figure 7 represents in side elevation a steel strip or bar from which the grating
of the fixed cutter is made.
Figure 8 is a diagram illustrating the manner in which the short pieces cut from
the strip Figure 7 are interlocked and

inner rings attached thereto by soldering or other means:
Figures 12 and 13 represent in side elevation and edge view the outer and inner
rings respectively used in making the fixed cutter Figure 11.
Figures 4 to 13 both inclusive are drawn to the same scale as Figure 3.
The same letters of reference indicate the same parts in the several figures
of the drawings.
a is the hopper; a' the barrel or cylinder and a³ the removable spout of the
mincing machine; c is the feeding screw and c its driving shaft. In the outer
end of the barrel or cylinder a² the fixed cutter b is situated, pins 63, 6 at opposite
points of the periphery or outer ring of the fixed cutter taking into internal
slots or notches in the end of the barrel a*. The shaft of the feeding screw c
bas bearings respectively in the sleeve at and in the inner ring of the fixed
cutter b. On the part of the shaft projecting from the sleeve a the handle or
winch d (when hand power is employed) is fixed by the thumb screw d. On the
inner end of the shaft is the ordinary rotating cutter e the said ordinary cutter
working against the inner face of the fixed cutter b. In addition to the rotary
cutter e employ a second rotary cutter f working against the outer face of the
fixed cutter b. The second or outer rotating cutter is fixed to the shaft c³ so as
to rotate therewith by a crossing pin ƒ engaging in a slot c³ in the end of the
said shaft c and the said cutter is kept in place by the nut g.
In making according to my invention the fixed cutter 6 of machines of the kind
hereinbefore described and illustrated I take a notched bar or strip of steel
Figure 7 and cut off pieces of varying lengths so that when put together in the
manner illustrated in Figure 8 they form a grating as represented in Figure 9 on
the outer part of which the ring and in the inner part the ring 63 may be cast.
Or rings of the kind represented in Figures 12 and 13 may be attached to the
grating by soldering or other means.
Although I prefer to make the fixed cutters or gratings with rectangular openings
in the way described yet I do not limit myself thereto as the grating, with
the rectangular openings, and its inner and outer rings may be made in one piece
by casting.
Both sides of the fixed cutter bare ground or polished so as to form the
edges of the crossing strips into sharp or cutting edges.
Although I prefer to use the double rotating cutters e, f in combination with
fixed cutters made according to my invention yet the said double rotating cutters
may be used in combination with an ordinary fixed cutter, that 15, with a fixed
cutter having circular or drilled holes.
Mincing machines made according to my invention readily mince suet and
other materials which can only be imperfectly minced by mincing machines of the
ordinary construction.
Mincing machines made according to my invention may either be used alone
or combined with other machines such for example as sausage making machines
and may be constructed to be driven by steam or other motive power.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that I claim
as my invention of "Improvements in mincing machines" ;-
First. In mincing machines in which the material to be minced is advanced by
a feeding screw against a grating or fixed cutter, the combination with the said
grating or fixed cutter of two rotating cutters one bearing against the inner face
and the other against the outer face of the fixed cutter substantially as described
and illustrated in the accompanying drawings.
Secondly. Forming the fixed grating or cutter of mincing machines of the
kind referied to in the prior claim from notched strips or bars interlocked or
engaged so as to form angular openings or cutting edges and secured by an
outer and inner ring attached by casting, soldering or by other means substantially

page_text: as described and illustrated in the accompanying drawings; also forming fixed
cutters or gratings with angular openings or cutting edges by casting substantially
as described.
