Improvements in Meat Chopping Machines.
We, CHRISTIAN HANS and JACOB FABER, both of Elberfeld, in the Kingdom of
Prussia, German Empire, 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:-
My invention has for its object certain improvements in incat chopping machines
so that the grade or fineness of the chopped meat may be altered without the usual
necessity of changing any wheels or the like. Furthermore according to my invention
the pitch on the feed-worm may be readily altered causing it to feed more or less
quickly as may be desired and without the necessity of altering the machines speed.
The manner in which I prefer to carry my invention into effect is shown in the
accompanying drawings of which fig. 1 is a section through the machine which is
shewn affixed to a wall while figs. 2 & 5 refer to certain details which will be explained
hereafter. Like letters refer to like parts in the drawings.
The machine consists of a cylinder (a) which may be clad internally with well-
known corrugations or ribs (a¹) the object of which are to stop the meat.
Perpendicularly in the centre of the cylinder is a shaft (1) carrying an adjustable
feed-worm (). The bottom of the cylinder is a perforated plate (c) in which the
bearing for the lower end of the shaft (¹) is embedded. The shaft (') is provided
with a threaded boss (²) on which sits a nut (3) pressing on a nave (*) of the
elastic worm (). The opposite end of the worm (b) is likewise provided with a
boss () which rests on the bottom (c). The boss (66) is firmly wedged to the
shaft (6) while boss (4) may be moved within certain limits up & down the shaft (61)
by means of the nut (63), although both bosses turn simultaneously with (b). The
two bosses (6º) and (b) are thus connected with each other through an elastic worm
which has the tendency to elongate itself towards the hopper and may be tightened
as required by means of the screw (63) which presses on boss b.
The larger the distance from to 65 gets, provided the length of the worm itself
be not altered, the larger is the pitch of the worm and the smaller its feeding power
and vice versa. In order to be able easily to make any such regulation from the
outside an opening with door d is provided in the wall of cylinder (a).
The shaft () is lengthened further upwards into the hopper e, the lengthening
piece being marked in the drawing (6) on which is affixed a toothed wheel which
turns the shaft, and sometimes I attach an elastic worm similar in construction to the
one in the cylinder and having a fixed boss g' and an adjustable boss which can be
moved up and down on the shaft 6 by means of the nut (67) whereby the pitch of
the worm (y) can be altered as required.
The upper
end of the shaft (6¹) or its addition 66 consists of the piece (68) which is
supported by the adjustable bearing (69) which is carried by the cross-bar / attached
to the upper edge of the hopper.
Such cross-bar may easily be removed from the hopper by loosening the screws h¹
and giving the bar a small turn in the direction indicated by arrow (fig. 5). The
hopper itself is attached in a similar manner to the cylinder a.
The shaft 6 receives its movement by means of the wheel f¹ the circumference
of which, with the teeth, is hidden between the hopper e and the cylinder a as shewn
in the drawing and the spokes (fig. 4) serve as cutters of the meat that is being
pressed from the hopper into the cylinder, the meat being in this manner pre-
liminarily cut.
The wheel is driven by wheel i fixed on the shaft k. and the latter receives its
motion from the conical wheels 1. and m and fly-wheel n
mechanisni.
or by any suitable

page_text: The mincing mechanisin proper are mainly affixed to the bridge which is connected
with the cylinder by screws or otherwise so that it can easily be removed.
Between the said bridge and the cylinder is placed a toothed wheel of having cutting
spokes like the wheel afore-mentioned and being altogether arranged like that. It
is fixed on the shaft (p) and actuated from cog wheel on shaft k. As shown in
drawing the wheel of is placed directly underneath the perforated disc or plate c.
Several more sets of perforated discs with cutter fixed on the shaft p may be arranged,
the meat passing through one after another. At last follows two perforated discs c²
and c³ placed in juxtaposition, with a cutter s¹ underneath. The knives s and si turn
with the shaft p, wheras the discs c³ is movable on the axes p by means of a lever c
which passes through the wall of bridge o, and according to the position of e³ to c²
the perforated parts of the one may be partly covered over by the non perforated
parts of the other, the passage being free when the perforations are juxta posited.
In fig. 2 the holes are shown juxta-posited while in Fig. 3 they are shewn in different
positions to each other. The desired position may be fixed from the outside by means
of screw and slit t¹ (fig. 3).
There may of course be several sets of similarly juxta-posited discs, with cutter
underneath, the meat passing through one set after another.
The top bearing of axis p is in the disc c, the lower bearing being the adjustable
bearing in the crossbar which latter may be removed by loosening the screws,
and turning it a little just as above described for cross bar h.
The shafts p and may be speeded either alike or different. In the drawings the
speeds have been assumed to be different, if they are alike then the shafts p & b may
be made in one piece and in such case the wheels o' and might be done away with.
The elastic worm & acts as a regulator under certain circumstances inasmuch as when
the feed is stronger than the mincing mechanisms can deal with the meat then it
forces itself back upon the worm causing it to elongate itself thereby feeding less
quickly.
In the drawings the machine is shewn attached to a wall w by means of bolts
and the vessel is placed under the machine for the minced meat to drop into.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what 1
claim is :-
In meat mincing machines:
1. The arrangement consisting essentially of pairs of perforated juxtaposited discs c²
and in connection with cutters & substantially in the manner as and for the purpose
described and as shewn in the drawings.
2. The method of employing flexible adjustable feed-worms g and b substantially
in the manner as and for the purpose described and shewn in the drawings.
3. The method of employing the spokes of the wheels and o¹ (which drive the
shafts 6 and p respectively) as cutters substantially as described and shewn in the
drawings.
