COMPLETE SPECIFICATION.
Improved Meat Cutting and Filling Machine.
I, HEINRICH CONRAD FRIEDERICH OTTE, of Lohmühlenstrasse 59, Altona,
Germany, Engineer, 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:—
Meat cutting machines heretofore ordinarily used, in which the meat is conveyed
by endless screws to the cutting appliances, have the disadvantage of pressing the
meat too much and squeezing out the juice so that raw meat is rendered inferior in
appearance and also becomes unsuited for being preserved, whilst cooked meat
cannot be treated in such machines at all. These drawbacks are obviated by the
use of a machine according to my invention which morcover is capable of being
rapidly converted into a sausage filling machine.
The machine is illustrated in the accompanying drawings in which Fig. 1 is an
elevation mainly in section and Figs. 2 and 3 are detail views.
a is a cylinder in which is arranged a piston that is capable of being actuated
by means of a rack c or other suitable device. The cylinder a has a cover d which
turns on hinges not shown, but of ordinary construction. Upon the cover is fixed a
feed hopper which is ordinarily kept closed automatically by a flap g provided
with a counterweight.
The capacity of the hopper is equal to the capacity of the cylinder a. On the
cover d is arranged laterally a tube in which the cutting appliance is situated.
This consists of two perforated steel discs w and we fixed on and rotating with a
shaft i, and knives and k' which are arranged in front of the discs and do not
rotate, and of which the former k has imparted to it a to and fro motion by means
of an eccentric or eccentric pin (see Fig. 3). The shaft i, which is movable end-
ways in its bearings, is driven by means of a crank applied at or by belt pulleys m,
as desired. The motion of the shaft i also effects the advance of the piston b, and
for this purpose there is fixed on the shaft a chain wheel n which through a chain o
and chain wheel p drives a second shaft g upon which is mounted a toothed wheel r
that engages with the rack c. Upon the shaft 7 there is also arranged a clutch s
by means of which the toothed wheel, can be put in and out of gear.
:-
To enable the machine to be used as a filling machine, the cover d is thrown back
and a covert is placed on the upper part of the cylinder a, this cover having a
tubular part u over which the skin to be filled is drawn. The opening for the
tubular part is closed during the cutting operation by a plug or stopper v (Fig. 2).
The operation of the machine is as follows:-
The meat to be cut is charged into the hopper f, and falls through the opening
in its lower part, (the flap y being opened by the weight of the meat) into the
cylinder a, the flap then closing automatically. The toothed wheel r is then
thrown into gear moving the rack c and the piston upwards. The meat is thus
pressed into the holes of the disc w, (which are larger than those of the disc w¹)
and is cut off by the knife k.
The meat thus cut up is then further pressed into the smaller holes of the disc w',
and cut off by the knife k', whereupon it falls out of the tube in a finely cut
condition into a vessel placed to receive it.
When all the meat in the cylinder has been driven through the cutting device
the piston is let down by throwing the toothed wheel r out of gear, the cylinder a
again filled, and the operation of the machine repeated until all the meat to be
treated has been cut up. Then the discs and knives are removed from the tube h
by moving the shaft i endways, the cover d.is opened, the cylinder a filled with cut
up meat, the cover inserted, the cover d replaced, the piston 6 moved up, and the

page_text: meat pressed through the tubular part into the skin which is slipped over
that part.
Instead of as above described, the piston may be driven in a direct manner, and
its motion utilized for obtaining therefrom the necessary power for actuating the
cutting device.
For this purpose there is provided below the piston a space
which is in
communication with a conduit y by which fluid pressure can be admitted as desired
under the piston.
On the upward movement of the piston, the shaft i will be caused to rotate
by means of the rack C. toothed wheel », shaft chain wheels p and n, and
chain o.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is: :-
1. A. combined meat cutting and filling machine comprising a cylinder a contain-
ing a piston b for forcing forward meat to be treated, a cover t having a tubular
part u and adapted to be fitted to the upper part of the cylinder when the machine
is to be used as a filling machine, and a cutting appliance, the latter operated by a
shaft that is either rotated directly and serves through gearing to move the piston b,
or is rotated indirectly through said gearing when the piston 6 is directly moved,
substantially as described.
2. In a meat cutting and filling machine of the kind referred to in Claim 1,
operating the knife kon the shaft by means of an eccentric or eccentric pin,
whereby a to and fro_movement is imparted to said knife, substantially as
described.
Dated this 11th day of March 1891.
