London, Patent Agent and Engineer, for an Invention of "A NEW OR
IMPROVED MEAT CHOPPING OR MINCING MACHINE." A communication
from abroad by Wilhelm V. Krause, of Neusalz, a/Oder, in the Empire of
Germany.

PROVISIONAL SPECIFICATION left by the said Walter Alfred Barlow at the
Office of the Commissioners of Patents on the 5th March 1881.
WALTER ALFRED BARLOW, of 6, St. Paul's Churchyard, London, Patent Agent
and Engineer. "A NEW OR IMPROVED MEAT CHOPPING OR MINCING MACHINE."
A communication from abroad by Wilhelm V. Krause, of Neusalz, a/Oder, in
the Empire of Germany.
The Invention relates to mincing apparatus for chopping meat and such like
soft edible material, and consists in the construction of the chopper mincing box,
which is entirely enclosed in a hinged cover or frame in which are placed the
knife holders.
The knife holders are blocks or plates provided with slots in which are disposed
the knives arranged in a row. These holders are placed in a bed or recess in the
boxing, and are so held by the hinged cover, one on each side of the central
revolving spiked drum or cylinder, the spikes whereof carry the material to be
chopped or minced against the inwardly projecting knife blades.
To prevent the knife holder from dropping out, a set screw is passed through.
and into the holders from the outside of the cover. The knives themselves are
made with shanks which retain the knives in position when placed in the holders,
and prevent their coming loose when machine is in motion, thus the knives are
readily removable for cleansing or repair.

by the said Walter Alfred Barlow in the Great Seal Patent Office on the
5th September 1881.
WALTER ALFRED BARLOW, of 6, St. Paul's Churchyard, London, Patent Agent
and Engineer. "A NEW OR IMPROVED MEAT CHOPPING OR MINCING MACHINE."
A communication from abroad by Wilhelm V. Krause, of Neusalz, o/Oder, in the
Empire of Germany.
This Invention relates to mincing apparatus for chopping or mincing meat and
such like soft edible material, and consists in the construction of the chopper
mincing box, which is entirely enclosed in a hinged cover or frame in which are
placed the knife holders.
The knife holders are blocks or plates provided with slots in which are disposed
the knives arranged in a row. These holders are placed in a bed or recess in the
said chopper mincing box, and when the boxing is closed are held by the hinged
cover, one on each side of the central revolving spiked drum or cylinder, the spikes
whereof carry the material to be chopped or minced against the inwardly projecting
knife blade.
To prevent the knife holder from dropping out from the top half of the mincing
box, a screw is passed through and into the holders from the outside of the cover.
The knives themselves are made with shanks and holes and holding pins, which
retain the knives in position when placed in the holders, when same are in position
in the boxing, and prevent them coming loose when the machine is in motion, thus
the knives are readily removable for cleansing or repair.
In order that the said Invention may be readily understood, I have hereunto
annexed a Sheet of Drawings wherein,―
Fig. 1 is an end view showing the general construction of the hinged frame or
boxing.
Fig. 2 is a side view from left hand of Fig. 1.
Fig. 3 is a cross section of Fig. 2 through line x, x, showing the knives and
spiked drum or cylinder in position for use.
Fig. 4 is a perspective internal view showing the spiked drum, and the beds or
recesses for reception of the knife holders.
Fig. 5 is a perspective view of the knife holder with the knives in position, and
the holding pins of the knives partly withdrawn.
Fig. 6, a front view of the knife holder without the knives.
The case or boxing A is divided into two parts connected on one side by a hinge,
and rests upon legs or standards, the top part being provided with a funnel or tube
to admit the material to be operated upon. Within said boxing are the knives and
knife holders B fixed in the beds or recesses C of the boxing with the screw c for
the top holder.
The stuff to to be operated upon is fed through the funnel or conduit A' on to a
spiked drum or cylinder D, which is revolved by means of a handle or other
convenient arrangement, and the stuff is pressed up against the knives, and is thus
chopped or minced, and then passes out of the apparatus by way of the lip a, or a
tube if desired into any desired receptacle.
The knife holders are made with slots therein at regular intervals corresponding
to the spikes of the cylinder for reception of the shanks or back parts of the knives,
and the top one is held firmly in position by means of a small screw e at the side,
which passes through the casing, see Figs. 2 and 4.
The knives are made crescent shaped with hooks or shanks at the back part to
take into the slots of the holder, and are held therein by means of pins passing
through the holder and the shanks of the knives, as shown in Figs. 5 and 6.

page_text: The following are the advantages of machines constructed according to this
Invention:-
The knives may be removed for cleansing or sharpening, and in case of breakage
for replacement of a new knife, and the knives are held securely in position.
Having now described the nature and particulars of the said Invention,
I claim,-
In a chopping or mincing machine, the construction and arrangement of the
knives and knife holders, for purpose of facilitating removal for cleansing and
sharpening purposes, and in case of breakage for replacement thereof, and securing
the knives and knife holders in position, substantially as herein set forth and
shown by the Drawings.
In witness whereof, I, the said Walter Alfred Barlow, have hereunto set my
hand and seal, this Thirty first day of August, in the year of our Lord One
thousand eight hundred and eighty one.
In presence of
ALFRED E. WELSH,
6, St. Paul's Chyd.,
London.
