Improvements in Machines for Cutting up Plastic or Yielding
Substances and Filling the same into Skins or other Receptacles.
I THOMAS WILLIAMS the Younger of 45 Myddelton Square in the County
of Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
This Invention relates to improvements in machines for cutting or mincing plastic
or yielding substances such as meat suet and the like wherein the substance to be cut
or minced, is forced by means of a feed screw, in a partially cut state through a
perforated plate revolving against a fixed knife or knives and filled into skins or
delivered into suitable receptacles by which improvements quicker and more certain
cutting and economy of construction are ensured.
The nature of the machine as constructed according to my invention is as follows:-
The casing is of the usual kind with internal spiral grooves employed in this class
of machine, and within it is the ordinary forcing screw formed with a journal at its
rear end passing through a bearing in the back of the casing to which journal the
handle or driving wheel is attached. This screw extends to within a short distance
of the perforated plate at the front end of the casing and through its axis passes a
spindle upon which a revolving cutter is loosely mounted for the sake of adjustment
yet so as to turn with it (the spindle being by preference made square or polygonal
at one end for that purpose). The said cutter has two three or moro blades all
revolving in the same plane through an opening in the centre of which cutter the
spindle passes. The cutting edges of these blades work against a stationary knife
extending across the casing between the revolving cutter and shoulder at the inner
end of the forcing screw and in contact with each. Upon the opposite side of this
cutter is another stationary knife also extending across the casing the cutting edge of
which is in contact with the inner face of a revolving perforated plate which is also
mounted upon the spindle and turns with it. Upon the outer side of said plate is a
third stationary knife similar to the others and having a cutting edge bearing against
its outer face. The extremities of all these stationary knives fit into longitudinal
slots or openings extending inwards from the front of the casing, and the spindle of
the machines passes through and turns freely within openings in the centre of said

page_text: knives. The supplementary propeller (described in the specification to my
patent No. 7125. A.D. 1886) for feeding the substances forced through the perforated
plate into skins or other receptacles is firmly fixed upon the end of the spindle and
bears at its rear end against the outer stationary knife. The perforated plate stationary
knives and revolving cutter being all threaded upon the spindle can be readily adjusted
by means of a nut on its rear end bearing against the end of the journal of the forcing
screw, by tightening which nut they may be drawn closely together and adjusted as
required. On turning the forcing screw, the spindle, (the square or polygonal
shaped portion of which extends a short distance into a corresponding recess in said
screw,) is rotated and with it the revolving cutter and perforated plate and supple-
mentary propeller, the meat or other substance fed in at the hopper being carried by
the forcing screw up to the said cutter between which and the first stationary knife it
receives its preliminary cutting, in this partially cut condition it is still forced onwards
till it reaches the revolving perforated plate which by its revolution completes the
cutting thereof against the stationary knives in contact with its respective faces the
completely cut meat being then forced if desired by the supplementary propeller,
which revolves within the usual adjustable feeding nozzle, into skins or other
receptacles.
A much thinner perforated plate than heretofore may be employed in this machine
without any fear of buckling owing to the support afforded thereto by the stationary
knives extending across either face which also prevent oscillation or side play of the
plate the advantage of using a thin plate being that the perforations are less liable to
become choked & the meat passes more quickly through them.
On detaching the handle or driving wheel all the working parts may be removed
together for the purpose of cleaning by simply removing the filling nozzle and with-
drawing them from the front end of the casing, which with the hopper is preferably
cast in one piece for the sake of economy.
Should it be desired to use the machine as a mincer only the supplementary
propeller may be dispensed with and a suitable head on the spindle substituted
therefor.

I THOMAS WILLIAMS the Younger of 45 Myddelton Square 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 :-
This invention relates to improvements in machines for cutting or mincing plastic
or yielding substances such as meat suet and the like wherein the substance to be
cut or minced is forced by means of a feed screw in a partially cut state through a
perforated plate revolving against a fixed knife or knives, and filled into skins or
delivered into suitable receptacles, by which improvements quicker and more certain
cutting and economy of construction are ensured.
Figure 1 is a sectional elevation of the machine.
Figure 2 is a horizontal section of the same.
Figure 3 is a view of the delivery end of the machine with the filling nozzle
removed.
Figure 4 is a transverse section taken along the line 1-2 in figure 1 looking from
the rear or feed end of the machine.
Figure 5 is a sectional view of the delivery end of the machine when used as a
mincer only.
Figure 5 illustrates a detached view of a modified form of forcing screw.
Figure 6 is a detached view of one of the stationary knives.
Figure 7 is a detached view of the revolving cutter.
Figure 8 is an elevation and Fig. 9 an end view of the filling nozzle.
A is the usual casing preferably cast in one piece and provided with the well known
internal spiral grooves. B is the hopper. the ordinary forcing screw, to the
journal at the rear end of which is suitably attached the handle or driving wheel D.
I have however found a better result to be obtained by the use of a forcing screw.
consisting of two three or more spiral blades or wings mounted on an axis, each
blade or wing making about one third (3rd) of a turn in its length as shown at (
figure 5 but 1 lay no separate claim to this form of forcing screw. Through the axis
of the forcing screw C passes a spindle E upon which is loosely mounted for the sake
of adjustment, yet so as to turn therewith (said spindle being by preference of a
square or polygonal section at one end for that purpose) a revolving cutter F, having.

page_text: two, three or more radial blades all revolving in the same plane and provided with a
square or polygonal shaped opening in the centre through which the spindle E passes.
The cutting edges of these radial blades work against the cutting edges of a stationary
knife a extending across the casing between the revolving cutter and the end of the
forcing screw. Upon the opposite side of the cutter F is the stationary knife of similar
construction to the knife a the cutting edge of which is in contact with the inner face
of a revolving perforated plate G also threaded upon the spindle E and rotating
therewith. A third stationary knife c of similar construction to a and bears with
its cutting edge against the outer face of the rotating perforated plate G. These
stationary knives a, b, and c are all threaded upon the spindle E which passes through
and can turn freely within circular openings in their centres and the extremetics of
the said knives rest in slots H formed in the ribs or projections I on the casing A.
K is the supplementary propeller for filling the cut or minced meat or other substance
into skins or suitable receptacles if required, and L is the filling nozzle both of which
may be of the kind described in the specification to my patent No. 7125 dated
May 27th A.D. 1886 with the exception that the propeller is not provided with a
cutting edge and is not in contact with the perforated plate, but bears against the
outer stationary knife c. The forcing screw, rotating cutter F, rotating perforated
plate G and stationary knives a, b and c being all threaded on the spindle E may be
simultaneously adjusted by turning a nut or wheel M on the rear end of the spindle
which on being tightened draws them all closely together by means of the supplementary
propeller K which is firmly attached to the spindle and bears against the outer
stationary knife. When the machine is to be used for mincing alone this supple-
mentary propeller may be dispensed with and a suitable head formed upon the spindle
in lieu thereof as shewn at K figure 5.
The action of the machine is as follows:-
On rotating the forcing screw, the spindle E' (the square or polygonal shaped
portion of which extends a short distance into a corresponding recess in said forcing
screw as shown in fig. 1) is rotated, and with it the revolving cutter F rotating
perforated plate G and supplementary propeller K (when the machine is to be used
as a filler also). The meat or other substance is fed in at the hopper B and carried by
the forcing screw Cup to the rotating cutter F between which and the stationary knife a
it receives its preliminary cutting. In this partially cut condition it is forced onwards
until it reaches the revolving perforated plate G which by its rotation completes the
cutting of the meat or other substance against the stationary knives b and c in contact
with its inner and outer faces respectively. The minced substance is then if desired
forced into skins or other receptacles by the supplementary propeller K in conjunction
with the filling nozzle L. Suitable notches Nare made in the periphery of the large
end of the nozzle as shewn in figures 8 and 9 to enable it to fit over the ribs I
on the casing, to which it may be secured by a thumb screw in the ordinary
manner.
In a machine constructed as herein before described, a much thinner perforated
plate may be employed than has heretofore been found practicable, all buckling and
oscillation of the perforated plate being avoided by reason of the support afforded
thereto by the stationary knives b and c which embrace it closely on either face, the
advantage of using a thin plate being that the perforations are less liable to become
choked or clogged, and the meat passes more quickly through them.
On detaching the handle or driving wheel all the working parts may be removed
together for the purpose of cleaning by simply removing the filling nozzle (when the
machine is employed as a filler also) and withdrawing them from the delivery end of
the casing.
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
1. The combination of the forcing screw C, rotating cutter F having radial blades
revolving in one plane, rotating perforated plate G, and stationary knives a, b, c,

page_text: extending across the casing, all threaded upon the spindle E, substantially as specified
and shewn in my drawings.
2. The combination with the rotating cutter, rotating perforated plate and stationary
knives of the forcing screw C¹ substantially as specified.
3. The combination of the rotating perforated plate & mounted upon the spindle E
with the stationary knives and extending across and embracing closely either face
of said perforated plate substantially as specified.
4. The simultaneous adjustment of the rotating perforated plate, stationary knives
and rotating cutter all threaded upon the spindle E by means of the nut or wheel M
on said spindle substantially as specified.
5. The combination with the revolving perforated plate stationary knives and rotating
cutter of the supplementary propeller K revolving in the mouth of the filling nozzle I
substantially as specified and shown in my drawings.
Dated the 7th day of February 1888.

Figure 1 is a sectional elevation of the machine.
Figure 2 is a horizontal section of the same.
Figure 3 is a view of the delivery end of the machine with the filling nozzle
removed.
Figure is a transverse section taken along the line 1-2 in figure 1 looking from
the rear or feed end of the machine.
Figure 5 is a sectional view of the delivery end of the machine when used as a
mincer only.
Figure 5 illustrates a detached view of a modified form of forcing screw.
Figure 6 is a detached view of one of the stationary knives.
Figure 7 is a detached view of the revolving cutter.
Figure 8 is an elevation and Fig. 9 an end view of the filling nozzle.
A is the usual casing preferably cast in one piece and provided with the well known
internal spiral grooves. B is the hopper. the ordinary forcing screw, to the
journal at the rear end of which is suitably attached the handle or driving wheel D.
I have however found a better result to be obtained by the use of a forcing screw
consisting of two three or more spiral blades or wings mounted on an axis, each
blade or wing making about one third (3rd) of a turn in its length as shown at C¹.
figure 5 but I lay no separate claim to this form of forcing screw. Through the axis
of the forcing screw passes a spindle E upon which is loosely mounted for the sake
of adjustment, yet so as to turn therewith (said spindle being by preference of a
square or polygonal section at one end for that purpose) a revolving cutter F, having
two, three or more radial blades all revolving in the same plane and provided with a

page_text: square or polygonal shaped opening in the centre through which the spindle E passes.
The cutting edges of these radial blades work against the cutting edges of a stationary
knife a extending across the casing between the revolving cutter and the end of the
forcing screw. Upon the opposite side of the cutter F is the stationary knife b of similar
construction to the knife a the cutting edge of which is in contact with the inner face
of a revolving perforated plate G also threaded upon the spindle E and rotating
therewith. A third stationary knife c of similar construction to a and b bears with
its cutting edge against the outer face of the rotating perforated plate G. These
stationary knives a, b, and c are all threaded upon the spindle E which passes through
and can turn freely within circular openings in their centres and the extremeties of
the said knives rest in slots H formed in the ribs or projections I on the casing A.
K is the supplementary propeller for filling the cut or minced meat or other substance
into skins or suitable receptacles if required; and-bis the filling nozzle both of which
may be of the kind described in the specification to my patent No. 7125 dated
May 27th A.D. 1886 with the exception that the propeller is not provided with a
cutting edge and is not in contact with the perforated plate, but bears against the
outer stationary knife c. The forcing screw, rotating cutter F, rotating perforated
plate G and stationary knives a, b and c being all threaded on the spindle E may be
simultaneously adjusted by turning a nut or wheel M on the rear end of the spindle
which on being tightened draws thein all closely together by means of the supplementary
propeller K which is firmly attached to the spindle and bears against the outer
stationary knife but I make no claim to the simultaneous adjustment of the various
parts by means of the nut or wheel M on the spindle E. When the machine is to be
used for mincing alone this supplementary propeller may be dispensed with and a
suitable head formed upon tho spindle in lieu thereof as shewn at K¹ figure 5.
The action of the machine is as follows:-
On rotating the forcing screw, the spindle E (the square or polygonal shaped
portion of which extends a short distance into a corresponding recess in said forcing
screw as shown in fig. 1) is rotated, and with it the revolving cutter F rotating
perforated plate G and supplementary propeller K (when the machine is to be used
as a filler also). The meat or other substance is fed in at the hopper B and carried by
the forcing screw up to the rotating cutter F between which and the stationary knife a
it receives its preliminary cutting. In this partially cut condition it is forced onwards
until it reaches the revolving perforated plate which by its rotation completes the
cutting of the meat or other substance against the stationary knives and e in contact
with its inner and outer faces respectively. The minced substance is then if desired
forced into skins or other receptacles by the supplementary propeller K. in conjunction
with the filling nozzle L. Suitable notches N are made in the periphery of the large
end of the nozzle as shewn in figures 8 and 9 to enable it to fit over the ribs I
on the casing, to which it may be secured by a thumb screw in the ordinary
manner.
