I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature,
of my invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :—
My invention consists partly of a meat cutter having its case formed to receive
a stationary knife, a rotary knife and a perforated disc.
It further partly consists of a rotary cutter effecting a double cutting action.
It also partly consists in the novel construction of the stationary cutter and the
perforated disc, whereby the shaft of the forcing screw is supported thereon.
It also partly consists of a novel fastening for the perforated disc.
It also partly consists of a rib on the interior of the casing to prevent the
packing of meat.
In the accompanying drawings.
Figure 1 represents a longitudinal section of a meat cutter embodying my.
invention.
Figure 2 represents an end view thereof.
Figures 3 and 4 represent views of the rotary and stationary cutters.
Figure 5 represents a section of the two cutters.
Figure 6 represents a horizontal section of a portion of the casing.
:
Figure 7 represents a view of a portion of a spout for a stuffer applicable to the
casing of a meat cutter.
Similar letters of reference indicate corresponding parts in the several figures.
A represents the casing of a meat cutter, the same being of a cylindrical form
and containing the forcing screw B, which has one of its journal bearings on one
end of the casing and the other on a perforated disc C, the latter being screwed to
said casing on the interior of the same.
.
D represents a stationary cutter which consists of blades D¹ radiating from a
hub D', said blades resting against a shoulder E on the inner face of the casing,
and having cutting edges a, and said hub having a circular opening F through
which the shaft B₁ of the screw B is freely passed.
t

page_text: Interposed between the cutter D and the disc C is a rotary cutter G, which
consists of blades G¹ radiating from a hub G³, said blades having cutting edges b.
The hub G has a squared or angular opening H to receive a similar shaped portion
of the shaft B¹, whereby the said cutter G rotates with the screw.
The disc C has a rim H¹, whereby it may be readily screwed and unscrewed,
and is serrated, corrugated, or otherwise toothed, as at J, for engagement of a dog
or pawl K which is pivotted to the casing A.
It will be seen that when the disc is screwed into the casing the pawl K
engages with one of the teeth J, and prevents unscrewing of said disc, whereby it
is reliably retained in position. When removal of the disc is required, the pawl is
raised, whereby it clears the tooth and the disc may then be unscrewed.
The operation of the cutter is as follows; When meat is supplied to the casing
it is forced by the screw successively through the stationary cutter, the rotary
cutter and the disc, it being cut first between the cutter edges a of the stationary
cutter and backs c of the blades of the rotary cutter, and next between the cutting
edges of the rotary cutter and the inner face of the disc, the latter acting as a
bed. It finally escapes through the perforations of the disc C, in streams which-
drop from the outer face of the disc and readily disintegrate.
A wiper L is fastened to the outer end of the stem B₁ of the screw, for cleaning
the disc of the the streams of meat and assisting in the disintegration thereof.
As the meat is subjected to two cutting actions, the cutting or mincing of the
meat is effectually accomplished.
.
The rotary and stationary cutters may be readily removed where dull or broken,
by unscrewing the disc C, it being noticed that when said cutters are in position
the screw shaft B₁ passes through the same, and it is supported on the stationary
cutter as well as on the disc, and thus firmly sustained. On the inner face of the
casing is a rib M, which extends transversely or circumferentially and ribs' N
forming corrugations which extend spirally or diagonally, the rib M being located
at or near the place of junction of the inlet portion of the casing with the main
body of said casing, it being seen that the the screw comes in contact with said
rib M, whereby the meat is primarily cut and prevented from packing in the inlet
portion of the casing and then directed into the main body of the casing where it
may expand into the corrugations or channels formed by the ribs N, preventing
clogging in the main body.
For stuffing purposes, the disc is removed and in lieu thereof I employ a conical
cap P, which is provided with a spout and has a threaded periphery whereby it
may be screwed to the casing, and a corrugated or toothed rim whereby it may be
engaged and held by the dog or pawl K.
Having now particularly described. and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
First. A casing having within the same a shoulder against which a stationary
cutter abuts, and an interior thread by which a perforated disc is connected with
the casing at the end thereof, substantially as described.
Second. In a neat cutter, a rotary cutter interposed between a stationary cutter
and a disc or bed, whereby meat is subjected to double cutting actions in its
passage through the casing, substantially as described.
Third. A casing having a forcing screw, a stationary cutter and a perforated
disc, the rotary cutter being between the stationary cutter and disc, whereby meat
is subjected to double cutting actions by the rotary cutter in its passage through
the casing substantially as described.
Fourth. In a meat cutter, a casing having a forcing screw, a stationary knife, a
rotary knife and a perforated disc, the shatt of the screw passing freely through
the stationary knife and entering the disc, and having the rotary knife connected
with it, substantially as described.

page_text: Fifth. In a meat cutter a perforated disc secured to the casing by a dog or
pawl which engages with a corrugation or serration on said disc, substantially as
described.
Sixth. A meat cutter having a casing and a forcing screw therein, said casing
being provided on its interior with a transverse or circumferential rib, substantially
as, and for the purpose, set forth.
Seventh. A casing with a forcing screw therein having an internally threaded
end, in combination with a stuffing spout or cap formed with a thread, whereby it
may be screwed to said case, and a corrugated or serrated rim, whereby by means
of a pawl on the casing the cap or spout may be locked in position, substantially
as described,
