COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Cutting Up Meat and
like Plastic. or Yielding Substances.
I, THOMAS WILLIAMS, the younger, of Bay Tree Cottage, Church End,
Finchley, London, N., 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:-
In the Specification to my Patent No. 2457 of 1890 there is described a machine
for cutting up meat and like plastic or yielding substances wherein the cutting is
effected by means of a revolving knife acting in conjunction with a cutting plate
having sharp edged grooves or channels formed in its face, the said. grooves or
channels converging towards and leading to a delivery or outlet aperture extending
through the centre of the said plate.
The present invention is designed to improve upon the above mentioned cutting
device, and to render the machine more rapid in action and easier to work.
This I. effect by the employment of a grooved or channelled cutting plate of the
peculiar construction and arrangement hereinafter described.
According to my invention, I so construct and arrange the grooves or channels
in the said cutting plate as to cause them to deliver the cut up meat around the
periphery thereof in lieu of through a central aperture therein as heretofore, said
grooves or channels preferably deepening as they approach the periphery of the
cutting plate in lieu of getting deeper towards the centre thereof as in the previous
arrangement. The said grooves or channels may be of equal width throughout, or
they may increase in width as they approach the periphery of the plate.
The meat or other substance cut up being delivered all round the periphery of
the plate in lieu of being delivered through an aperture in the centre thereof, it is
obvious that there will be less resistance or obstruction to its exit. and that the
machine will consequently work more quickly and easily, whilst at the same time
all the advantages of the perfect scissor cut afforded by the use of a grooved or
channelled cutting plate are retained.
My invention further relates to a sbutter device in the form of a perforated ring
applied round the periphery of the cutting plate whereby the outlets by which the
meat is delivered when cut up may be reduced. in size as desired. The delivery
may thus be more or less retarded if necessary, as when fine cut meat is required
for example.
I will now proceed to more particularly describe my invention and the manner of
performing the same, and for that purpose will describe the accompanying drawings
in which similar letters refer to like parts in all the figures, and in which:-
Fig. 1 is a front view and Fig. 2 is a part sectional edge view of the cutting
plate.
Figs. 3 and 4 are similar views of a cutting plate of slightly modified
construction.
Fig. 5 shews a convenient form of revolving knife.
Fig. 6 shews the shutter device.
Fig. 7 is a longitudinal section of the delivery end of a meat cutter having my
invention applied thereto.

page_text: Fig. 8 is a sectional edge view of the cutting plate represented in Fig. 7, the face
view of which plate would be similar to Fig. 3.
A is the cutting plate and a are the grooves or channels formed in the face
thereof said grooves or channels leading to the periphery of the plate A and
preferably deepening as they approach the same. In Fig. 1 the grooves or
channels a widen as they approach the periphery of the plate, whilst in Fig. 3 they
are represented as of the saine width throughout. In this last mentioned fig. also,
and in Fig. 8, it will be noted that the grooves or channels are cut right through
the cutting plate A at the periphery thereof and this construction of the grooves or
channels will be found useful when extremely quick delivery is desired and a fine
cut is not needed. The face of the cutting plate A is ground and faced true so as
to impart sharp cutting edges to the grooves or channels a therein, and the cutting
up of the meat is effected in a similar manner to that described in the Specification
to my above mentioned Patent 2457 of 1890, viz., by means of a knife revolving in
cutting contact with the face of the said cutting plate, the meat being forced
against the grooved or channelled face of the cutting plate by a forcing screw or
equivalent device and being severed by a succession of perfect scissor cuts as fast as
it enters the said grooves or channels.
In Fig. 7, which shews the application of my invention to a meat cutter, & is the
delivery end of the usual casing having the well-known longitudinal (or spiral)
internal ribs c. d is the forcing screw upon the axis e of which is mounted so as to
revolve therewith the knife f, the blades of which are preferably curved or of
scimitar shape, as shewn in Fig. 5. The said axis e of the forcing screw passes
through a central aperture formed for its reception in the cutting plate which
latter closes the delivery end of the casing b, and said axis e is screw threaded at its
end to receive the adjusting nut h and lock nut whereby the cutting plate is held
in place and its proper adjustment in relation to the kuife is maintained. The
cutting plate A must project sufficiently beyond the end of the casing b, as
illustrated, to permit of the peripheral delivery of the cut meat outside of said
casing. are projections on the cutting plate A which enter corresponding
recesses in the casing band which prevent the said cutting plate from revolving
with the knife f.
In Fig. 6 is a ring having perforations k¹ formed around it. This ring k may
be applied around the periphery of the plate A, fitting the same closely yet free to
be turned thereon, and acts as a shutter whereby the outlet apertures around the
periphery of A may be more or less obstructed or reduced in size, for the purpose
above mentioned, by turning the ring on the plate, as will be clearly understood on
referring to the drawing.
Although in the drawings I have represented the grooves or channels a as being
radial and straight, I do not confine myself to this precise arrangement, since
tangential, curved or bent grooves may be employed provided they deliver the
cut meat around the periphery of the cutting plate. prefer however the
arrangement illustrated.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In machinery or apparatus for the purpose set forth, the cutting plate A having
grooves or channels a formed in its face and leading to its periphery, whereby the
cut up substance is delivered around the periphery of the cutting plate in
lieu of through a central aperture therein as heretofore, substantially as described.
2. The combination with the grooved or channelled cutting plate A having
peripheral delivery, of the perforated ring or shutter k, substantially as and for the
purpose specified and illustrated.
3. The use in combination with a casing, a forcing screw or equivalent device
and a revolving knife, of the grooved or channelled plate A having peripheral
delivery, substantially as described and illustrated.

page_text: 4. In machinery or apparatus for the purpose set forth, a cutting plate A having
peripheral delivery and constructed and arranged substantially as illustrated in the
annexed drawings.
