I THOMAS WILLIAMS the Younger of 45 Myddelion Square in the County of
Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
Machines for cutting up plastic or yielding substances such as meat suet and the
like wherein the substance to be cut is forced either in a crude state or in a partially
cut condition against or through perforations in a plate fitted to the delivery end of
a cylindrical or other shaped casing the final cut being effected by the combined action
of the edges of the perforations and one or more rotary knives working in close
contact with the inner or outer, or both inner and outer faces of the said perforated
plate are well known but machines of this description although well adapted for
cutting up or mincing meat or other like substances, are not adapted for forcing at the
same time the cut substance into skins. They have therefore either been supplemented
by a separate and distinct machine known as a "filler" or stuffer for effecting the
last mentioned operation separately or they have been made convertible into a "filler"
by the removal of the perforated plate and knives working against the same and the
substitution therefor of a filling nozzle in order to render the machine suitable for
forcing the cut substances into skins after it has performed the cutting or mincing
operation but in no case has the said class of machines been so constructed as to
perform both the operations of mincing and filling simultaneously.

Now my invention consists in the use in combination with the aforesaid class of
mincing machines of a filling nozzle and a special propelling screw the latter being
situate on the outer side of the perforated plate and enclosed within the tapering or
funnel shaped mouth of the filling pipe or nozzle fitted in any convenient or well

page_text: known manner to the delivery end of the casing of the compound machine. The
special propelling screw is by preference mounted upon the front end of the axle or
spindle of the main forcing screw or rotating barrel of the machine which is extended
through the centre of the perforated plate for that purpose. The function of this
special propelling screw is to take the cut or minced portions of the meat as fast as
they fall from the perforations in the plate and propel them forward into the skin.
When using two knives or seis of knives revolving in contact with both the inner
and outer faces of the perforated plate the outer knife may consist of the inner end of
the special propelling screw itself revolving in close contact with the outer face of the
perforated plate and sharpened to a cutting edge.

page_text: 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 the well known class of mincing machines
in which a perforated plate is employed in conjunction with a knife or knives revolving
in close contact with the inner, or outer, or both inner and outer, faces of the said
perforated plate for effecting the cutting operation whether the substance to be cut is
forced against and through the said perforated plate in the uncut or crude state in
which it is fed in through the mouth or hopper or after it has been partially cut in the
machine.
Machines of the class referred to although well adapted for performing the single
operation of cutting up or mincing meat or other like substances are not adapted (by
reason of the obstruction offered by the perforated plate) for simultaneously mincing
and forcing the cut substance into skins and have therefore either been supplemented
by a separate and distinct machine known as a "Filler" or "Stuffer which effects
the last mentioned operation separately or they have been converted into a "Filler**
by removing the perforated plate and knives working against the same, and substi-
tuting therefor a filling nozzle the machine thus converted being then suitable only for
forcing the cut substances into skins by a separate operation.
The object of my invention is to enable a mincing machine of the said class to
perform efficiently both the operations of mincing, and filling into skins simultaneously
thus constituting an improved combined or compound mincing and filling machine.
To this end my invention consists in the combination with a mincing machine of
the class referred to of a filling nozzle fitted in any convenient or well known manner
to the delivery end of the casing and a supplementary rotary propeller situate on the
outer side of the perforated plate and enclosed within the tapering or funnel shaped
mouth of the filling nozzle said propeller being mounted upon the front end of the
axle, or spindle of the main forcing screw or rotating barrel of the machine which is
extended through the centre of the perforated plate for that purpose. The special
function of this supplementary propeller is to take the finally cut or minced portions
of the meat after they have passed through the perforations in the plate and propel
them onwards through the filling nozzle into the skins.

page_text: I prefer that the blade or spiral of the supplementary propeller shall make only
about a half turn round its axis and that its inner, end which revolves in close contact
with the outer face of the perforated plate shall be sharpened to a cutting edge so as to
act as a knife against the outer face of the said plate.

Similar letters refer to similar parts throughout the several views.
Referring to Figures, 1, 2, 3, 4, 5 and 6, a is the casing of my improved combined
or compound machine, divided longitudinally, the upper half being made to open
on hinges or to slide longitudinally on to the lower half as is well understood and
provided with the usual feeding mouth or hopper c. is the spindle of the rotary
barrel contained within the said casing and driven by hand or by power. It is sup-
ported at the front end in an opening in the centre of the perforated plate & through
which it protrudes and at the opposite end in a long bearing e formed in the two halves
of the casing. As here shown the rear portion of the spindle has mounted thereon
or formed in one therewith an archimedean propelling screw by preference of wider
pitch at that part immediately under the feeding mouth. The forward portion of the
spindle carries a series of revolving knives g suitably spaced and working through
slots in two plates fixed in recesses on opposite sides of the lower and upper
hinged portions respectively of the casing. The first or inner knife of the series y
works against the front edges of the plates as shown in Figure 2 in lieu of in a
separate slot of its own. The ordinary and well known cutting device used very
generally in mincing machines may be substituted if desired consisting of stationary
Knives fixed inside the casing and revolving arms or claws mounted spirally on the
corresponding portion of the barrel or vice versa. The crude or uncut substance as it
is fed in is propelled forward by the action of the screw to the cutters, which effect.
a preliminary cutting of the substance before it is finally brought under the combined
cutting action of the stationary perforated plate d and the knives or star like cutter /
(fig. 4). The cutter is mounted on the end of the spindle c of the barrel so as to
revolve in close contact with the inner surface of the perforated plate d. kis the
supplementary propeller also fixed on the end of the spindle c', it revolves outside the
perforated plate and is enclosed within the conical mouth of the filling tube or
nozzle. This nozzle is removeably fitted for the purposes of cleaning into the
annular groove or recess inside the delivery end of the casing which receives the
perforated plate as shown in figure 1.or it is passed over the end of the casing and
secured by a pinching screw m as in figure 5.
The inner end of the supplementary propeller k may be sharpened to a cutting edge
at´¹ (fig. 6) so as to operate as a revolving knife against the outer face of the

page_text: perforated plate d in conjunction with the star like cutter on the inner face. The
supplementary propeller can be tightened up against the perforated plate by a nut n
or by screwing the propeller directly onto the protruding end of the spindle clas
shown in fig. 5. The same adjustment of the supplementary propeller serves also to
force the perforated plate & well up to the cutters the recess or groove which receives
the plated being sufficiently wide to allow of its adjustment, therein. The supple-
mentary propeller shown in figures 1 and 2 has two convolutions of the spiral or
thread but a better action is olitained with only about a half turn as shown in the
modification-figures 5 and 6.
1 form in the interior of the casing of my improved compound mincing and filling
machine a series of spiral grooves o so shaped as to present an obstacle to any back-
ward movement of the substances under treatment whilst allowing of its free advance
towards the delivery end of the machine, are the usual fastenings for securing the
upper half of the casing in its closed position when mounted on hinges.
The interior of the filling nozzle when used in combination with the supplementary
propeller and perforated plate & may be circular as shown in figures 1, and 5, but I
prefer to make it with eccentric sides forming internal longitudinal shoulders or
projections as shown in fig. 7 to assist the forward movement of the minced meat
by checking any tendency it may have to rotate with the supplementary propeller
inside the mouth of the filling nozzle. Or the interior of the mouth / may be formed
with spiral angular shaped grooves s as shown in fig. 8 to assist the action of the
supplementary propeller.
In the types of existing mincing machines figures 9 and 10 the substance operated
upon is forced in an uncut condition by a forcing screw against a stationary
perforated plate d and is cut by a knife revolving in close contact either with the
inner surface of the said plate (see figure 9) or with the outer surface thereof (see
figure 10).
In figure 11 the substance is partially eut inside the casing by cutters before it
reaches the perforated detaining plate the final cut being effected by the knives i
revolving in close contact respectively with the inner and outer faces of the
plate d.
In all these three types of the class of machine before referred to the functions of
the machine ceased when the substance had passed through the perforations in the
plate d no provision being made for imparting any further impulse to the cut sub-
stance which fell inertly from the perforations and had to be fed into a separate and
distinct filling machine when required to be forced into skins.
Now by the combination as shown with a mincing machine of the class referred to
of the filling device consisting of the nozzle and supplementary propeller k
revolving therein on the outer side of the perforated plate a fresh impulse is imparted
to the minced substance by which it is forced into skins direct as fast as it issues
through the perforated plate.
I am aware that prior to my invention mincing machines have been made wherein
the meat was cut by spirally disposed rotary knives or claws alone which served
also to propel the cut substance through a filling nozzle and therefore I do not claim
broadly the effecting the two operations of mincing and filling by one and the same
machine.
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 in a compound mincing and filling machine of a filling nozzle
and a supplementary propeller revolving in the mouth thereof, with a perforated cutting
plate having knives revolving in close contact with either or both its faces and a forcing
screw inside the casing of the machine as specified.
2. The combination in a compound mincing and filling machine of a filling nozzle
and supplementary propeller revolving in the mouth thereof with a perforated cutting
plate fixed in the end of the casing having knives revolving in close contact with its

page_text: inner face, and a rotary barrel carrying a forcing screw and a series of cutters working
against slotted plates fixed on opposite sides of the interior of said casing substantially
as specified and shown in figures 1, 2, and 3 of my drawings.
3. In a compound mincing and filling machine the supplementary rotating
propeller formed with a cutting edge revolving in close contact with the outer face
of a perforated cutting plate fixed into the delivery end of the casing as specified.
4. The combination in a compound mincing and filling machine of a conical filling
nozzle having eccentric sides and internal longitudinal shoulders or projections
with a supplementary propeller and a perforated cutting plate having knives revolving
in close contact therewith as specified.
5. The combination in a compound mincing and filling machine of a conical filling
nozzle having internal spiral angular shaped grooves with a supplementary propeller
and a perforated cutting plate having knives revolving in close contact therewith as
specified.
