MENTS IN APPARATUS FOR CUTTING OR MINCING SAUSAGE MEAT AND OTHER LIKE SUBSTANCES
Year: 1884

page_text: 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 APPARATUS FOR CUTTING OR MINCING SAUSAGE MEAT AND OTHER LIKE
SUBSTANCES 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 certain improvements in that class of mincing machines
wherein a cutting device is ordinarily employed consisting of either a number of
claws spirally disposed upon a barrel or spindle rotating inside a cylinder or case
and working between a series of stationary knives (which I prefer) or a number of
rotating knives working through slots in one or more slotted plates fixed inside the
cylinder or case the said case being provided with a feed hopper near one end
thereof through which the meat or other substance to be minced is fed into the
machine and with or without the usual filling nozzle at the opposite end of the
machine.
A great objection to machines of the class above referred to as heretofore
arranged is that they mince or reduce the meat or other substances too fine owing
to the substance operated upon being propelled too slowly through the machine
and consequently remaining too long under the action of the cutting or mincing
device. Moreover owing to the mouth of the hopper opening directly onto the
revolving claws or knives as the case may be the meat was frequently forced back
into the hopper by their action.
Now the chief object of my Invention is to obviate the aforesaid objections by
ensuring an unimpeded, a quicker, and a more certain or positive delivery of the
meat or other substance through the machine which I accomplish by combining in
the peculiar manner hereinafter described with the aforesaid cutting device a
continuous or unbroken threaded achimedean propeller the cutting device being
situate in the forward portion only of the cylinder or case that is to say away from
under the mouth of the hopper whilst the said archimedean propelling screw is
situate at the rear end of the rotating barrel or spindle and immediately beneath
r

page_text: the mouth of the hopper. I thus combine the advantages of the free and
unimpeded delivery obtained by the spirally disposed rotating claws or mincing
knives with the quick and positive feed of the archimedean propeller rendering
the improved machine better adapted for delivering (or filling into skins when
required) whilst at the same time obviating the objectionable tendency of the
ordinary arrangement of mincing machines to force the meat back into the hopper
by the action of the revolving claws or knives hitherto situate under the feed
aperture of the hopper. I may if found desirable combine with my improved
arrangement the well known inclined or spiral blades or arms frequently attached
to the front extremity of the barrel or spindle and opposite the entrance to a
centrally disposed filling nozzle in order to assist in forcing the meat or other
substance after it has been minced through the said discharge orifice or nozzle.
Figure 1 of my Drawings represents a longitudinal vertical section of my
improved mincing machine taken along the line 1-2 in Figure 2.
Figure 2 is a corresponding plan showing the cylinder or case open with the
spinde or barrel in position.
a is the cylinder or case which may be of the usual construction and which is
here shown as fitted with a filling nozzle b at the lower portion of the front end
thereof as is well understood. c is the feeding hopper formed on the rear end of
the upper half a¹ of the case which is hinged at a to the lower or fixed half.
e e¹ are collar bearings the two halves of which are cast on the upper and lower
portions of the case respectively. f is the barrel or spindle rotated by a winch-
handle (not shown in my Drawings) fitted thereon at g or by any other convenient
arrangement. h h are journals formed at the front and rear ends respectively of
the barrel or spindle and rotating in the collar bearing e e'. i is the continuous or
unbroken threaded archimedean propeller or screw situate immediately beneath the
mouth of the hopper c and by preference cast in one with the barrel or spindle f.
kk are rotating claws fixed in any suitable or well known manner round the barrel-
spirally. are two opposing sets of stationary knives fixed by screws or otherwise
in recesses in the opposite sides of the lower and upper halves respectively of the
cylinder or case, between which fixed knives the claws k work. In my Drawings
I have only considered it necessary to show by way of example the well known
cutting device composed of rotating claws and fixed knives in combination with
the archimedean propeller i disposed directly beneath the mouth of the hopper, but
it is to be understood that a cutting device consisting of rotating knives working
through fixed slotted plates may be employed, provided that either of these cutting
arrangements be situate as shown in my Drawings in the forward part of the
cylinder or case and away from the mouth of the hopper.
The minced meat may be delivered into skins or otherwise as required either
through a central or lateral discharge orifice provided or not with the usual nozzle
as preferred.
In working my improved machine the meat falls directly from the hopper
between the continuous threads of the archimedean propeller i which at once urges
it (without any tendency to force the meat back into the hopper) along the body
of the cylinder to the cutting device by which a quicker and more positive feed or
traverse of the meat along the cylinder is ensured with an unimpeded delivery of
the same.
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 :-
The application and use in machines for mincing meat and other substances of a
revolving continuous or unbroken threaded archimedean screw propeller situate
immediately underneath the mouth of the feed hopper in combination with a
cutting device consisting either of spirally disposed revolving claws working
between fixed knives or of spirally disposed revolving knives working through

page_text: fixed slotted plates and situate at the forward part only of the cylinder or case so
as to be away from the mouth of the feed hopper substantially in the manner and
for the purposes hereinbefore described and illustrated by my Drawings.
