A communication from PECK STOW & WILCOX COMPANY, of Southington, in
the County of Hartford and State of Connecticut, in the United States of
America.
1. ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention and in
what manner the same is to be performed, to he particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in meat cutters and the main objects of
the improvement are to increase the efficiency and durability of the machine, and
to provide for the more convenient and better adjustments of the parts.
In the accompanying drawings-
Figure is a perspective view of the meat cutter.
Figure 2 is a central longitudinal section of the same with the screw adjusting
rod in elevation.
Figure 3 is an end view of the screw or combined forcer and cutter.
Figure 4 is an elevation of the knife, showing its inner side.
Figure 5 is a side elevation of one part of the case, showing its inner side, and
Figure 6 is a plan view of a portion of the perforated plate.
This invention is in the nature of an improvement upon the meat cutter patented
in England to Amos Shepard No. 10,090 and is substantially the same in its
general form, but such changes in the construction thereof have been made as to
adapt it for use in connection with a perforated plate and knife while at the same
time a new adjustment is provided for the knife that works against said plate,
which plate and knife are also applicable to other meat cutters.
On the delivery end of the two parts A, B, of the longitudinally divided and
separable case is formed an inwardly projecting ledge 7, holding said parts together
by the clamp like standard C Fig 1. One of said parts, preferably the part A, is
also provided with a steady pin or lug 8 adjacent to said ledge 7 as shown in
Figs. 2 and 5. These parts, A, B, inay be otherwise substantially the same as in
the aforesaid Patent, with the long and short feeding ribs 9, 10 and series of
cutting elevations 11 with spaces between, as shown in Fig. 5.
The combined forcer and cutter which for convenience will be called the screw D,
is made to fit the case, is provided with a shank or shaft like projection 12 for the
attachment of any suitable crank as shown by the crank end 13, the crank being
represented as broken off in order to economise space. This screw is bored through
longitudinally with a portion of the bore threaded and a screw adjusting rod 14
screwed therein as shown. In the center of the delivery end of the screw is formed
an angular socket 15. A perforated plate E preferably of disk form, that is
having two like sides, placed between the two parts of the case just inside the
ledge 7 and with the pin or lug 8 projecting into the notch 16 Fig 6 of said plate.
Inside of sai perforated plate is a knife 17 with any desired number of arms,
preferably four, and an inwardly projecting angular hub 18, which is fitted
loosely to and rests within the angular socket in that end of the screw.
After use the principal parts will be separated for cleaning. When it is desired
to use the machine again the knife hub is placed within its socket at the end of the
screw D, the screw and knife together placed within one of the parts of the case,
preferably the part A, the perforated plate placed in position between the ledge 7
and the knife, and with the notch 16 in engagement with the pin 8,'the other part of
Prin Rd]

the case put on over the screw, knife, and plate, and the whole secured within the
standard. The crank may not have been taken off, but if so, the knurled head of
the screw adjusting rod 14 is small enough so that the crank can be put on without
removing said rod. This rod is then turned to force the knife properly against the
perforated plate. The same act will also have a tendency to force one side of the
cutting elevations on the case and engaging side walls of the grooves in the screw
into active engagement, even if the two parts of the case have not been firmly
bound upon the screw or in case they are worn so as not to fit. The action of the
screw and case on the meat is the same as in the aforesaid Patent, the first part of
the screw near the hopper forcing the meat along while the cutting elevations of the
screw and case act to cut the meat to a greater or less extent dependent upon
the number of cutting elevations and the pitch of the grooves and ribs on the
screw. The pitch at the cutting elevations can be varied at pleasure to obstruct
the flow of the meat or to let it flow more rapidly. After passing the end of the
screw the meat is further reduced by the action of the perforated plate and the
knives bearing thereon In this machine the screw is firmly held in its bearings
by being bound on its peripheral portions by the two parts of the case so that it
cannot rock to make the knife accommodate itself to the face of the perforated
plate.
By having the knife arranged as described with the rounded end of the screw
adjusting rod bearing on the end of its hub like a pivot or step the knife is free to
rock and accommodate itself to the inner face of the perforated plate so as to
insure a good cutting bearing thereon at all points.
It is preferable in all cases to employ a case and screw which shall materially
cut the meat before it reaches the perforated plate as meat so cut is believed to run
through the perforated plate more readily and with greater ease than when the
perforated plate and knife alone are depended upon to do the principal cutting, but
it is evident that while the improved plate and knife are particularly adapted to
Co-operate with the particular screw and ease herein described the construction is
also adapted to an ordinary forcing screw and case in which the principal cutting
is done by the perforated plate and its knife. It is also preferable to make the
angular knife helding socket in the end of the screw and the angular hub as a
projection on the knife but the projection and socket might be reversed and have
the same screw adjusting rod act in connection therewith.
Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondents, and the manner in
which the same is to be performed, I wish it to be understood that I do not limit
myself to the precise details herein described and illustrated, as the same may be
varied without departing from the nature of this invention, but what I claim is
:-
1. The combination of a meat cutter case, its screw, the knife fitted thereto by
an engaging angular recess and projection, the perforated plate and the screw
adjusting rod extended through said screw for forming a step or pivot upon which
the knife may rock, substantially as described and for the purpose specified.
2. The combination of a longitudinally divided and separable case having a
series of cutting elevations, a combined forcing and cutting screw having a series of
peripheral grooves in bearing contact with said elevations, a perforated plate and
knife, and an adjusting device for forcing said plate and knives against each other
and at the same time forcing the cutting elevations and grooves of the screw and
case into engagement, substantially as described and for the purpose specified.
