MENTS IN MACHINERY OR APPARATUS FOR MINCING SAUSAGE MEAT AND FILLING
THE SAME INTO SKINS "to be as follows:-
This Invention consists in the combination together on a single bed plate or
casting of a silent Mincer composed of knives rotating within a revolving bowl and
a filler consisting by preference of an Archimedean screw and spirally disposed
claws or knives revolving within a cylindrical or slightly conical casing the barre!
of the Filler being driven from the knife shaft of the Mincer and the hopper
thereof being placed in communication with the bowl of the latter by a removeable
feed duct or spout combined with a plough or scraper in the bowl of the Mincer in
such manner that the minced meat shall be automatically discharged from the said
bowl into the hopper of the Filler by being urged up the inclined surface of the
plough or scraper and along the feed duct by the rotation alone of the bowl thus
obviating all handling of the minced meat by the attendant. The plough or
scraper and feed duct are hinged or otherwise so mounted as to be brought into
or out of action as required whilst provision is also made for throwing the Filler
into or out of gear by the aid of fast and loose driving pulleys or clutch coupling.
The bed plate of the machine and the necessary bearings for the knife shaft and
the spindle or barrel of the Filler are cast in one piece for cheapness of construction.
In order to prevent corrosion of the bowl of the Mincer I make it of "white
metal"
or an alloy of tin and antimony. It is rotated by bevel gearing a bevel
pinion on a short spindle being caused to gear into a horizontal bevel wheel situate
above the bed plate and formed with a central boss or socket into which a short
central stud cast in one with the bowl is secured. The cover plate of the bowl,
through a slit in which the knives work, is made in a single piece and can be
readily removed for the purposes of cleaning or emptying the bowl by loosening
the attachments which connect the cover plate to the bearings of the knife shaft.

page_text: The knives are secured to the knife shaft in a somewhat similar manner to that
described in the specification to my patent No. 732 A.D. 1880 but in order to
enable any one knife of the set to be separately loosened and adjusted without
interfering with the rest I divide across the centre the loose collars which are
situate on each side of the central fixed boss and through which collars the
tightening screws pass, each half collar corresponding to a separate knife and
having its own countersunk tightening screw. The machine may be driven either
by hand or by power. When driven by hand the spindle carrying the pinion
which imparts the rotary motion to the bowl may be fitted with a winch handle
and provided with a spur wheel gearing into a smaller spur wheel on the knife
shaft but when driven by power the knife shaft will by preference constitute the
first motion shaft and be provided with fast and loose driving pulleys as is well
understood.

I THOMAS WILLIAMS the Younger of 45 Myddelton Square in the County of
Middlesex Engineer do hereby declare the nature of my invention for " IMPROVE-
"
MENTS IN MACHINERY OR APPARATUS FOR MINCING SAUSAGE MEAT AND FILLING
THE SAME INTO SKINS and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-
This Invention consists in the combination together in one machine of a Silent
Mincer consisting of knives rotating within a slowly revolving bowl-a Filler of
any well known construction but by preference consisting of an Archimedean
screw revolving within a cylindrical or slightly conical casing and a feeding device
for automatically feeding the meat after it has been minced direct from the
revolving bowl of the Mincer into the Filler without necessitating the handling
of the minced meat by the attendant. The said compound or combined machine
may be driven either by hand or by power but in either case the knife shaft
of the Mincer and the screw shaft or spindle of the Filler are connected together
by gearing or driving bands either of these shafts constituting the first motion
shaft or both the said shafts may be driven from a third or separate driving shaft
common to the two. A removeable plough or scraper in the bowl of the Mincer is
so combined with the hopper of the Filler that the minced meat shall be auto-
matically directed from the said bowl into the hopper of the Filler by the combined
action of the plough or scraper and rotary motion of the bowl. The plough or
scraper and hopper or feed duct are hinged or otherwise so mounted in the machine
as to be readily brought into or out of action as required whilst provision is made
for throwing the Filler itself into or out of action by the aid of fast and loose
driving pulleys or by any well known clutch arrangement.
The bed plate of the machine and the necessary supports for the knife shaft and
Filler are made in one casting for cheapness of construction. The bowl is driven
from a short borizontal spindle or shaft worked from the knife shaft and carrying
A bevel pinion gearing into a horizontal bevel wheel situate above the bed plate
and carrying the bowl of the Mincer. The cover plate of the bowl (through slits
in which the knives work as is well understood) is made in one piece and can be
readily removed when required by loosening the attachments which connect it to
the supports of the bearings of the knife shaft or other convenient fixed part of the
machine. The knives are secured to the knife shaft in a somewhat similar manner
to that described in the specification to my patent N° 732 A.D. 1880 but in order
to enable a single knife of the set to be removed or adjusted without loosening any
of the rest I divide diametrically the outside loose collars situate on each side of
the central fixed boss each half collar corresponding to a separate knife of the series
and having its own countersunk tightening screw which passes only through its
own particular knife. Or the loose collars may remain undivided provided each of
the tightening screws therein passes only through its corresponding knife but as

page_text: the withdrawal or loosening of one of the screws in the complete or undivided
collar will tend to loosen the hold on the adjoining knife held by the same collar
I prefer the arrangement first described.
Figure 1 of the drawings annexed is an end elevation of my improved silent.
Mincing and self feeding Filling machine as arranged to be driven by power.
Figure 2 is a corresponding front elevation and partial longitudinal section of the
same. Figure 3 is an elevation looking on the driving end of the machine.
Figure 4 is a plan corresponding to Figure 2. Figure 5 is a detail front elevation
of a portion of the combined machine as arranged for being driven by hand.
Figure 6 is a detail edge view and partial vertical section illustrating my improved
mode of securing the knives of the silent Mincer to the shaft. Figure 7 is a side
elevation thereof and figure 8 is a detail of one of the knives detached.
A is the silent Mincer, B the Filler and C the plough or scraper forming a
portion of the self acting feeding device all carried by the single bed plate a of the
combined machine. This bed plate has cast thereon the supports bb for the
bearings of the knife shaft c and bowl actuating spindle or shaft & as well as
the supports e c for the casing f of the Filler. is the main driving strap mounted
on a pair of fast and loose driving pulleys h on the knife shaft c which carries a fly
wheel and a pulley and strap or suitable gearing for transmitting motion to the
short spindle d. This spindle carries a bevel pinion m in gear with a horizontal
bevel wheel the axis of which constitutes the vertical axis of the revolving
bowl and turns in a footstep in the bed plate immediately above the surface of
which the bevel wheel n revolves. p p are rotary curved knives which may be of
the usual construction working inside the bowl in the well known manner. q is
the cover plate to the bowl made in one piece and attached at r to the pillow
blocks of the knife shaft bearings so as to be readily removeable when required.
The said knives work through slits in the cover plate and are protected by the
usual hood not shown in my drawings 8 is a pulley for transmitting motion from
the knife shaft to the spindle of the Archimedean screw t of the Filler through the
strap and fast and loose pulleys the shifting of the said strap enabling the
Filler to be thrown into or out of action as required.
If preferred toothed gearing may be substituted for transmitting motion from
the knife shaft to the Archimedean screw of the Filler. The feed duct or hopper w
of the Filler is separately hinged at x to the upper part of the casing of the Filler
which is made removeable as is well understood but a portion of this hopper is
extended over the edge and down inside the bowl of the Mincer so as to form an
inclined plough or scraper C which guides the minced meat upwards and over the
edge of the bowl direct into the feed duct or hopper of the Filler.
In figure 1 I have shown in dotted lines the plough or scraper and hopper in
the position they would occupy when turned up out of action by depressing the
handle y formed on the hopper. When arranged for being driven by hand I prefer
to make the spindle or shaft t of the Filler the first motion shaft mounting thereon
a spur wheel z provided with a handle and gearing into a smaller spur wheel 1
fast on the knife shaft as shown in. the detail figure 5 and by the corresponding
dotted pitch lines in figure 3. In this case the driving wheel may be mounted
loose on the shaft t and coupled therewith by an ordinary friction or other clutch
not shown in my drawings so as to enable the Filler to be thrown out of action
whilst the Mincer is still at work. The knife shaft should by preference be driven
at the rate of say three revolutions to one of the expelling screw of the Filler.
When the screw shaft constitutes the first motion shaft and is geared direct to the
knife shaft in the manner shown in figures 3 and 5 the thread or inclination of the
screw will be in the reverse direction to that shown in figure 2.
2, 2, in figures 6 and 7 represent the outer divided or semicircular collars for
holding the knives 2 in position on the knife shaft by screws 3, passing through
the said half collars and corresponding knives and entering a short distance into
the fixed collar 4 of the shaft as shown, The knives are by preference each formed

page_text: with an open rectangular slot 5 see figure 8 in order to admit of a single knife
being readily removed and replaced on slackening its corresponding screw without
disturbing the rest. The knives may either be disposed in pairs so that two
knives of the series shall always be cutting simultaneously as described in my said
former specification or they may be arranged as shown in my drawings annexed so
as to cut singly in succession.
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 a Silent Mincing Machine a Filler and a Feeder so
arranged that the minced meat is automatically transferred direct from the lowl
of the Mincer to the hopper of the Filler substantially as herein before described.
2. In a combined Silent Mincing Machine and Filler wherein the Filler is
automatically fed from the bowl of the Mincer, driving the shaft of the Filler from
the knife shaft of the Mincer or vice versa or driving both shafts from a separate
driving shaft common to the two as hereinbefore described.
3. The peculiar arrangement for separately securing and releasing any one of
the knives of the knife shaft of a silent mincing machine without disturbing the
rest of the series as hereinbefore described.
