Improvements in Meat Cutters.
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:-
In addition to simplicity and economy of construction, the following are essential
features in a good meat cutter:-
(a) All the cutting should take place near the delivery end of the casing, and
the thread or spiral of the forcing screw should extend uninterruptedly up to
the cutting devices. (b) The cutting should be of a scissor or shear like type.
(e) The cutting devices should offer as little obstruction as possible to the exit of.
the meat.
Now whilst meat cutters have been employed wherein the thread or spiral of the
forcing screw extends uninterruptedly to cutting devices, situated at the delivery
end of the casing and having a scissor or shear like cutting action, the said cutting
devices have been found to offer too much obstruction to the exit of the meat.
The object of the present invention is to produce a meat cutter of simple and
economical construction which will embody all the essential features above set
forth. This 1 effect by means of the construction and arrangement of cutting
devices hereinafter described.
According to my invention, the cutting device 1 employ consists of a disc
provided with a number of radiating or projecting arms or ribs around its periphery,
the device somewhat resembling a cog or worm wheel. The edges of the said arms
or ribs are brought to a sharp angle or cutting edge. The said device is to be
mounted upon and rotates with the axis of the forcing screw, and is situate at or
near the delivery end of the casing. As the cutting device rotates, cutting takes
place between the edges of the arms or ribs thereof, and short sharp edged cutting
ribs, formed around the interior of the delivery end of the casing, and running in a
longitudinal, or slightly angular, direction. The coacting edges of the arms or ribs
of the cutting device, and of the ribs within the casing, should be at a slight angle
in relation to one another, in order to ensure a scissor or shear cut being imparted
to the substance passing between them.
I take up any wear that may occur between the said cutting ribs within the
casing, and those of the rotating cutting device, by causing their coacting faces to
incline towards the interior of the casing, the cutting device being in the form of a
frustrum of a cone, having its smaller diameter facing the interior of the casing;
perfect adjustment may then be effected by simply moving the cutting device in
I find a
the line of its axis, by any convenient arrangement of adjusting screw.
convenient method to be, to provide an adjusting nut on the handle end of the axis
of the forcing screw, which, when tightened up, will draw the said forcing screw
and cutting device toward the rear end of the casing. In order to prevent the
meat from escaping too readily, I prefer that the spaces between the arms or ribs
of the cutting device should be somewhat smaller upon the outer or delivery, than
upon the inner side thereof.
If desired, the above described cutting device may be cast in one with the
forcing screw, at the delivery end thereof, also the before mentioned cutting ribs
within the casing might be formed around the interior of a ring adapted to fit:
within a seating in the casing, in lieu of being cast upon the interior of the casing
itself.
It will readily be seen that by the employment of the above described cutting
device a number of cuts may be given to the meat within a small space, whilst at"

page_text: the same time far less obstruction is presented to the delivery or exit of the meat,
than by the perforated or grooved cutting plates or equivalent devices heretofore
employed.
The meat may be cut fine or coarse as desired by increasing or diminishing the
number of the cutting ribs or arms.

Improvements in Meat Cutters.
I THOMAS WILLIAMS the Younger of Bay Tree Cottage, Church End,
Finchley, 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 meat cutters of that type wherein the
cutting up of the meat is effected solely between ribs formed around the interior
of the sides of the casing and peripheral cutting devices rotating within such
casing.
In addition to simplicity and economy of construction, the object of my inven-
tion is, 1, To render such machines quicker and more efficient in action. 2, To
leave as little residue as possible within the casing after the cutting up has been
effected, thereby avoiding waste.
I attain these results by the construction and arrangement of meat cutter herein-
after described, an essential feature of which consists in presenting an unobstructed
path or channels for the passage of the meat from its entry at the hopper to its
delivery in a cut up condition from the exit end of the casing. According to my
invention I employ a casing the interior of which enlarges gradually from the
hopper towards the outlet end. Within the outlet or larger end of the casing
I place a peripheral cutter, consisting of a rotatable cylindrical core, provided
around its periphery with a number of projecting cutting ribs, set at a slight angle
to, and maintained in cutting contact with, similar cutting ribs formed around the
interior of the outlet end of the casing, and extending in a longitudinal or approxi-
mately longitudinal direction. The ribs of the casing and of the peripheral cutter
being set at an angle to one another, a scissor like cut is imparted to any substance
passed between them. The meat is ted up to and forced between the cutting ribs
by means of a forcing screw situated beneath the hopper, the thread of which
terminates at and does not intersect the cutting ribs, thereby leaving the grooves
or channels between such ribs unobstructed for the passage of the meat. The said
peripheral cutter may either be cast in one with the core of the forcing screw, or
constructed separately and secured upon the axis thereof.
The peripheral cutter and forcing screw are of corresponding taper with the
interior of the casing, and proper adjustment between the cutting ribs of the casing
and those of the rotating peripheral cutter may consequently be readily effected
by moving the said cutter longitudinally within the casing by any convenient
arrangement. A simple method will be hereinafter described with reference to the
drawings.
In the accompanying drawings in which similar letters refer to corresponding
parts in all the figures:-

page_text: g. is a horizontal section of the casing on line 1-2 Fig. 1, showing the
cutting and feeding ribs therein.
a is the casing the interier of which enlarges gradually from the hopper b to the
outlet. A is the forcing screw, upon the axis of which is mounted the crank d.
3B is the peripheral cutter here shewn as cast in one piece with the forcing screw A,
but if desired it may be constructed separately and secured upon the axis thereof.
This cutter B consists of a cylindrical core around the periphery of which are
formed the cutting ribs e the sharp edges e¹ of which coact with the sharp edges fl
of the cutting ribs formed around the interior of the outlet end of the casing a.
Between the cutting ribs e and of the cutter and casing respectively, are left the
unobstructed grooves or channels g g'. I prefer that these grooves or channels 99
should gradually diminish in depth and width towards their outlet ends so as to
keep the meat under the action of the cutters until properly cut. I also prefer to
bevel or slightly round off the inner ends of the ribs e and f so as to facilitate the
entrance of the meat into the grooves or channels gg'. hh are longitudinal feeding
ribs within the casing a which coact with the thread or worm of the forcing
screw A and prevent the meat from simply revolving with the latter. It will be
seen on referring to the drawings that the feeding and cutting devices are kept
quite distinct the feeding ribs and spirals i terminating when they reach the
cutting ribs fe. consequently avoid all obstruction to the passage of the meat
through the machine as is the case in some machines where the feeding and cutting
ribs are caused to intersect one another, and I present an unobstructed path or
channels for the passage of the meat from its entry at the hopper to its exit.
I effect the proper adjustment between the cutting ribs e and f by means of the
thumb screw screwed into the end of the axis e of the forcing screw. This thumb
screw bears with its head upon and holds in place the crank d and upon being
tightened up draws the forcing screw and peripheral cutter towards the rear of
the casing thereby taking up any wear that may have occurred between the cutting
ribs e and f.
The action of the machine is as follows
-:
The meat introduced by the hopper 6 is carried forwards by the forcing screw A
and forced into and through the grooves or channels go between the cutting
ribs e and receiving during its passage a succession of shear like cuts from
such ribs.
When it is desired to use the machine for filling also, I may provide the casing
with a convenient filling nozzle and pipe as shewn in Fig. 5, where n represents a
filling pipe and nozzle secured to the casing a by a convenient screw o.
The machine may be caused to cut either coarse or fine as desired by varying
the size of the channels g g between the cutting ribs e and f, making them larger
for coarse cut, and smaller for fine cut meat, or, when a filling nozzle and pipe are
employed, by increasing or diminishing the bore of the pipe. The fineness of the
cut may also be regulated by the length of the cutters. I find however that as a
general rule a length of cutter approximately the same as one diameter of the
cutting device at its largest end answers best.
Having now described and particularly ascertained the nature of the said
invention and in what manner the same is to be performed, I would observe in
conclusion that I am aware that a machine of the type herein referred to has been
proposed wherein a combined forcer and cutter consisting of a cylindrical core
provided with intersecting longitudinal and spirally disposed ribs or knives, acts in
conjunction with intersecting longitudinal and spirally disposed ribs or knives
around the interior of a casing, and that I lay no claim to such an arrangement as
forming part of my invention but I declare that what I claim is:-
1. A meat cutter of the type herein set forth wherein all the cutting is effected
at the outlet end of the casing by means of peripheral cutting devices as described,
and wherein the feeding or forcing ribs which impel the meat between and through

page_text: the cutting devices terminate at, without intersecting, the ribs of such cutting
devices, substantially as and for the purpose specified.
2. A meat cutter constructed with a casing, cutting ribs formed round the
interior of the outlet end thereof, a peripheral cutter acting in conjunction with
the cutting ribs of the casing and consisting of a rotatable core provided around
its periphery with cutting ribs having between them unobstructed grooves or
channels, and forcing ribs extending up to and terminating at the cutting ribs,
substantially as and for the purpose specified.
3. In a meat cutter, in conibination, a casing enlarging gradually towards its
outlet end, cutting ribs formed around the interior of such outlet end, a peripheral
cutter as above set forth rotating in cutting contact with said cutting ribs, a
forcing screw extending up to and terminating at the peripheral cutter, and
means for effecting the adjustment between the cutting ribs of the casing and
peripheral cutter substantially as described.
4. In a meat cutter, in combination with cutting ribs around the interior of the
outlet end of the casing and running in a longitudinal or approximately longitudinal
direction, a peripheral cutter consisting of a rotatable cylindrical core provided
around its periphery with cutting ribs, set at a slight angle or inclination to the
cutting ribs on the casing, and having between them unobstructed grooves or
channels, substantially as described and illustrated.
5. The combination with the cutting ribs around the delivery end of the
casing a, of the rotating cutter B provided around its periphery with the cutting
ribs having between them unobstructed channels contracting towards their
outlet ends, substantially as described and illustrated.
6. The combination of the casing a enlarging gradually towards its outlet,
cutting ribs around the outlet end thereof, peripheral cutter B, forcing screw A,
and adjusting nut & substantially as described and illustrated.
