COMPLETE SPECIFICATION.
Improvements in Apparatus for Mincing Meat and other like
Substances.
I, PETER JENSEN, of 77, Chancery Lane, in the County of Middlesex, Fellow of the
Institute of Patent Agents, 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, a communication to me from abroad by Edwin
Balkley of 2548 Callowhill Street, Philadelphia, in the County of Philadelphia and
State of Pennsylvania one of the United States of America, Gentleman :-
This invention relates to meat cutters and has for its object the provision of a
machine for more rapidly mincing meat without expressing the juices thereof and for
mincing suet, etc., which will be simple and compact in construction, readily accessible
to all its parts for cleansing and which will be light, efficient and durable.
The improvement consists in having the feed chamber shallow, and the wall opposite
the cutting plate inclined to form a wedge shaped space between the said wall and
cutting plate, the larger end of the space being the entrance or mouth to the chamber.
The feeder is arranged between the cutting plate and the end wall of the chamber or
case and consists of a series of armis radiating from a shaft that passes centrally through
These arms are beveled
and is journaled in the closed end of the case or chamber.
on their front edge to wedge the meat etc., between them and the cutting plate and
force it through the openings and against the cutting edges of the plate. The cutting
plate is provided with a series of discharge openings a depression or pocket being
formed in front of each opening to permit the meat to come square against the cutting
edge which is formed at the rear side of the opening. The rear side of each opening
is beveled outward to form a keen cutting edge and the depression or pocket for the
next opening is formed by beveling from the said edge of the preceding opening which
thereby increases the cutting capacity of the said cutting edge. The openings are
preferably oblong, being long and narrow, and arranged tangentially to the center of
the cutting plate so as to obtain a shear or draw-out.
The improvement further consists of the peculiar construction and combination of
the parts which hereinafter will be more fully described and claimed and shown in
the annexed drawings, in which
Figure 1, is an elevation taken from the end of the apparatus when the power is
Applied

page_text: Figure 2, is a like view taken from the opposite end, the end plate and cutter
being removed.
Figure 3, is also a like view, the end plate only being removed.
Figure 4, is a vertical central sectional view of the meat cutter.
Figure 5, is an inner face view of the end plate of the apparatus.
Figure 6, is a section on line, a, a, of figure 5.
Figure 7, is a sectional view of one of the radial cutter arms.
The case, A, provided with the legs, a, and the hopper, C, is shallow and is open at
one end and closed at the opposite end by the wall, B, which is inclined or of spiral
form, thus forming a wedge shaped chamber between it and the cutting plate, D, which
closes the open end of the case. The cutting plate, D, has notches, d, in its edge which
correspond to the position of the lugs, e, projecting from the case and the inclined
blocks or wedge shaped ways, e', at the ends of the notches ride under the lugs, e, when
the plate is turned and force the said plate close to the case. The plate is turned by
any suitable means, the thumb pieces, E, being provided for the purpose.
The discharge openings, F, in the cutting plate are oblong and tangentially arranged
to the center of the plate and have their rear sides beveled outward to form the
edges, The depression or pocket, 1, formed in the plate in front of each opening
is tapering and has its origin at the cutting edge, thus the pocket or depression for
one opening commences at the cutting edge of the opening immediately in front of
the said opening as will be readily understood.
The feeder, G, is arranged between the cutting plato and the wall, B, of the case
and consists of the arms, g, extending from the shaft, H, that is or may be journaled
in the end, B, of the case and provided with the crank, h, on its outer end. These
arms are beveled on their front side to wedge the meat etc., between them and the
cutting plate and crowd it against the cutting edges and force it out through the
discharge openings.
The meat or other substance is placed in the hopper and the feeder set in motion by
rotating the shaft, H, the said substance is forced into the narrow end of the chamber
and at the same time crowded against the cutting edges of the openings in the cutting
plate and forced out through the said openings ready for use.
The machine can be readily and thoroughly cleaned by detaching the cutting plate
and removing the feeder. The cutting plate is removed by rotating it until the notches
therein correspond with the lugs, e, when it can be easily detached.
The foeder is lifted out by detaching the crank on the end of the shaft, H. The case
being shallow and broad can be easily cleansed. The discharge openings in the cutting
plate being narrow at one end and wide or flaring outward roadily admit of their being
thoroughly cleansed as will be readily comprehended.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed, I declare that what I
claim is
1. In a meat cutter a case having a wedge shaped space or chamber between the end
of the case and the cutting plate, substantially as and for the purpose specified.
2. In a meat cutter a case having the wall opposite the cutting plate inclined,
substantially as and for the purpose described.
3. In a meat cutter the case having the wall opposite the cutting plate spirally
inclined, substantially as shown for the purpose described.
4. In a meat cutter the combination with the case and the cutting plate of the
feeder having its arms in substantially the same vertical plane and inclined on their
front sides, substantially as and for the purpose described.
5. In a meat cutter the cutting plate having its cutting edges tangential to circles
which circles are concentric with the center of the said plate, whereby a draw or shear
cut is effected.
6. The berein described cutting plate having a series of oblong openings and
having one side of the said openings beveled to a cutting edge, substantially as
set forth.

page_text: 7. The herein described cutting plate having a series of openings, and having
depressions in the plate in the front of the openings, substantially as and for the
purpose described.
8. The herein described cutting plate having a series of openings and having one
side of each opening beveled to an edge and having a depression in the face of the
plate extending from the said edge to the next opening substantially as and for the
purpose described.
9. The herein described cutting plate having a series of oblong openings which are
tangentially arranged and have one side of the said openings beveled to an edge, and
having depressions formed in the face of the plate directly in front of each opening,
substantially as set forth.
Dated this 31st day of May 1888.
