This invention relates to an improvement in that class of meat-cutters which
consist of a case having a hopper at one end through which the meat may be
introduced, a follower arranged to revolve upon a longitudinal axis within the case,
the follower having a spiral blade which will force the meat introduced through
the hopper along through the case, the interior of the case and the periphery of the
follower from the hopper toward the other end of the case of corresponding
shape, and the surface of each provided with spiral ribs which co-act to cut the
meat as it is forced through between that part of the follower and the case, and
delivered through perforations at the end of the case opposite the hopper, and
which perforations produce a supplemental and final cutting of the meat as it is
delivered from the machine, the object of the invention being a simple construction
whereby the machine is made in few parts, readily cleaned and very effective in its
work, and it consists in the construction as hereinafter described and particularly.
recited in the claim.
A, represents the case, B, the hopper; that portion of the case immediately
below the hopper is of cylindrical shape, but from the hopper forward toward the
delivery end of the case, the interior of the case preferably gradually contracts in
diameter, producing a conical shape. Upon a longitudinal axis within the case the
follower C, is arranged, which consists of an arbor extending through the hopper
end of the case, to which power may be applied in the usual manner. On the
follower is a collar D. which is adapted to close the hopper end of the case, that
end of the case being left open for the withdrawal of the follower. The hopper is
provided with the usual spiral blade, E, so that the meat which is introduced
through the hopper will be forced forward by the revolution of the follower and .
blade E. That portion F, of the follower within the case forward of the hopper
is of conical shape, corresponding to the internal shape of the case, and this part
of the follower is constructed with a series of spiral ribs G, and the case is
constructed with corresponding spiral ribs H, the ribs G and H being adapted to
co-act so as to cut the meat as it is forced through between the follower and the
case. The delivery end I, of the follower is of a diameter corresponding to the
delivery end of the case, and so as to substantially fill the case at that point, as
seen in Fig. 2. From the case inside the end I, of the follower, openings J, are
made, more or less in number, and which openings lead into passages K, which
open through the end of the case as at L, see Figs. 2 and 4, consequently the meat
which is cut by its passage between the revolving follower and the case, will be

page_text: forced through the openings J, into the passages-K; and thence escape through the
openings L, in the end of the case. A disk M, is attached to the end of the
follower, and this disk is constructed with a series of perforations N, see Fig. 3,
which are adapted under the revolution, of the disk to work across the openings L,
of the case, and so that the meat which passes through the openings L, will enter
the perforations N, in the disk, and, because of the revolution of that disk, that
portion of the meat which passes into the perforations in the disk will be cut as
those perforations, pass the openings in the case, and thus produce a supplemental
cutting of the meat as it is delivered from the machine. The disk is fixed to a
shaft, which extends longitudinally through the follower, and at its opposite end
the shaft O, is provided with a nut P, so that when the crank, or whatever the
power may be, is applied to the end of the arbor the nut on the shaft O, will bear
against the end of the arbor, tending to draw the follower and perforated disk
together and to proper. bearings in the case, and as clearly seen in Fig. 2. The
force thus applied to the nut tends to draw the follower and disk together, so
adjusts the disk and follower with relation to their respective cutting surfaces, that
is to say, it will tend to draw the follower forward to bring its cutters into closer
contact with the corresponding cutters of the case, and also to draw the disk M,
into closer contact with the surface upon which it works. The disk is engaged
with the follower so as to positively revolve therewith. This engagement-is
produced by means of a stud Q on the hub of the disk which sets into a corre-
sponding notch R, in the end of the follower.
Preferably that portion of the disk in which the perforations are made, is of
conical shape, and the end of the case is correspondingly recessed, as clearly seen
in Fig. 2, but other forms may be employed, as for illustration a plain flat surface
between the disk and case, as seen in Fig. 7.
The spiral cutting ribs of the case, as well as the spiral ribs of the follower
should be, fitted with considerable nicety, and present sharp angles to each other, in
order to give a shear like cut to the meat as it passes between the ribs on the two
parts.
While preferring to make the openings J, into passages which lead through
openings in the end of the case, these escape passages may be in the form of
grooves made in the end of the case, as seen in Fig. 7, it only being necessary that.
there shall be escape passages from the cylinder near its delivery end corresponding
to the working surface of the disk.
"By this construction the supplemental cutting is produced by the arrangement of
the revolving supplemental cutters outside the case, so that no space for the
supplemental cutters is required inside the case, the result of this is a more
positive cutting, and less of a grinding character than can be produced where
the supplemental cutters are arranged inside a stationary perforated plate. Again,
by this arrangement of the supplemental cutters, the preliminarily cut meat will all
be forced through the case, so that but a trifling amount of meat is left within the
case, when the work is complete. The parts are easily separated and easily cleaned.
there are no small parts liable to loss in the cleaning or adjusting of the machine,
and the simple character of the machine makes it extremely durable.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents I declare that what I claim is :-

adapted to force the meat from the hopper forward within the case, and that:
portion of the follower from the, hopper forward corresponding in shape to the
interior of the case, and provided on its surface with series of cutting ribs adapted
