Improvements in Machines for Chopping or Dividing Meat and
the like.
I, JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of London
Gentleman do hereby declare the nature of this invention (which has been com
municated to me from abroad by The Enterprise Manufacturing Company of
3rd and Dauphin Streets, Philadelphia, Pennsylvania United States of America)
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 machines for chopping or
dividing meat or the like the said machines being of the perforated plate type, in
which the meat or the like is forced to the plate and there cut. The object of this
invention is to make the machine so that it will consist essentially of two parts,
one removeable as an entirety from the other so as to avoid misplacing loose pieces.
A further object of this invention is to arrange the parts so that the feed screw
will have its bearing solely in the casing. The invention relates further to the
details of the machine as hereinafter fully described with reference to the
accompanying drawing in which :-
:-
Fig. 1 is a sectional elevation of a machine constructed in accordance with this
invention.
Fig. 2 is a sectional view illustrating a modification; and
Fig. 3 is a rear view of a chopper shewing an interrupted screw.
A is the casing, preferably mounted on a base or leg A₁, adapted to be secured
to a table or shelf by a screw a'. The discharge end A² of the casing is conical
and has a series of holes a through which the cut neat or the like passes. A³ is a
hopper communicating with the interior of the casing A.
A feed screw D fits snugly within the casing A and the casing is in fact the sole
bearing or support for this screw. The casing A is preferably provided with longi-
tudinal or other ribs a' so that the meat or the like will be conveyed by the screw D
and forced through the holes a and cut by the edges of the said screw in combination
with the edges of the walls of the holes a in the casing A.
In the example illustrated the screw snugly fits the tapered portion A' of the
casing A and finds a bearing there, and has at the rear a flange d which snugly fits
the rear of the casing A and constitutes a rear bearing. As the relation of the two
bearings of the casing are always the same it is impossible for the screw D to get
out of line.
This
The screw D has an increased number of threads at the cutting end, in the
example shewn, so that the meat or the like will be cut without undue packing.
B is an annular follower which surrounds the shank d¹ of the screw D.
follower has a screw threaded periphery adapted to screw threads in the walls of
the opening in the back of the casing, which opening is sufficiently large for the
withdrawal of the screw D.
The hole in the follower B is somewhat larger than the shank of the screw,
so that the feed screw D takes its bearing solely in the casing A and not in the
follower B the follower being simply for the purpose of forcing the end of the
screw D up against the conical portion A² of the casing A so that the cutting edge
will be in contact.
The follower B may have a broken screw thread engaging with the interrupted
thread on the casing, as shewn in Fig. 3.

page_text: Between the follower B and the shouldered portion d of the screw D is a washer e
having a portion e¹ entering a slot a³ in the casing. By placing this washer e
between the screw D and follower B the accidental turning of the follower B when
the screw D is turned is prevented. On the end of the shank d' is secured the
handle D¹.
When the screw D is detached from the casing A the follower B and washer e
remain on the screw D being confined thereon by the handle, so that there are no
loose parts to be mislaid.
To put the parts together the feed screw D is simply passed into the casing A
and the follower B is then screwed into the casing A until the feed screw D
bears against the conical portion A2 of the casing A when the machine is ready
for use.
To cleanse the machine, after using, the screw portion can be readily detached
from the casing, and both the casing and screw cleansed without the liability of
mislaying detached small parts.
In some instances the rear bearing of the casing may be removable with the
screw, as shewn in Fig. 2, the said rear bearing being in the form of a disc a
having a tapered periphery which, when the screw D is in place, rests in a tapered
portion of the casing A, as shewn. A spring a may be inserted between the
disc a and follower B which spring will tend to keep the disc a* in place.
Having now particularly described & ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is
1. The combination in a machine for chopping or dividing meat or the like of
a casing made in one piece and having a hopper, a perforated and tapered forward
end and an open rear end, a combined feed screw and cutter adapted to be inserted
into the said casing through the opening in the rear end, and having a shank to
which the handle is secured and a follower adapted to be secured to the open end
of the casing and having an opening greater in diameter than the shank of the
feed screw, whereby the combined feed screw and cutter has its bearing solely in
the casing, the follower being fiee from contact with the shank, and serving only
as a means of forcing the cutting portion of the feed screw against the perforated
and tapered front end of the casing, substantially as hereinbefore described.
2. The combination in a machine for chopping or dividing meat or the like, of a
casing made in one piece and having an open rear end, a hopper, a straight body
with straight longitudinal ribs therein, and a perforated and tapered front end, the
said ribs terminating at the perforated end portion, with a combined feed screw
and cutter, having its bearing within the casing, and a follower adapted to the
open rear end of the casing and acting to force the cutting portion of the feed
Berew against the perforated portion of the casing substantially as hereinbefore
described.
3. The arrangement and combination of parts constituting a machine for chopping
or dividing meat or the like substantially as herein before described and illustrated
in the accompanying drawings.
