I WILHELM SCHEFFEL of Remscheid in the Empire of Germany, Manufacturer, do
hereby declare the nature of this invention to be as follows
These improvements in meat-chopping machines relate firstly to the motion of the
knife-shaft. Hitherto the knife was rotated just as quickly as the conveyor, that
conducts the meat to the knife. Owing to this the meat could never be dissevered
completely especially when there were sinews in it. In the present improvement the
knife is rotated quicker than the meat-conveyor. This is effected by fixing the
conveyor loosely on the knife-shaft and by driving then the conveyor and knife-shaft
at different rates of speed.
The second improvement to be mentioned is, that owing to the knife-shaft, being driven
separately, that is to say independently of the conveyor, the motion of the knife-shaft
can be accelerated or reduced. By this means it is possible to cut the meat coarser or
finer as may be desirable.
The third improvement to be mentioned is, that another knife may be fixed to the
conveyor shaft, so that this knife on the conveyor shaft, which latter rotates more
slowly than the knife shaft, acts as a cutter to the knife of the knife-shaft. In the latter
case either both or one of the knives are provided with lateral notches to prevent the
meat; getting between them, from being forced out of the machine.
The chopping block, against which the knife lies and cuts by its rotating, was
stationary as yet and the knife operated against it, but the chopping-block can also be
made to rotate in the opposite direction to that in which the conveyor rotates. These
motions can easily be given to these parts by means of the knife-shaft, on which the
conveyor is loosely fixed and moved by a separate wheel.
It is evident, that the most material points in what has just been said are, that the
conveyor sits loosely on the knife-shaft and can be rotated in a direction different to
the latter or at different rates of speed or both.
In order to prevent the meat from rotating with the conveyor longitudinal mould-
ings are applied to the casing of the apparatus. They may be formed like screws.
These mouldings offer a certain resistance to the meat and prevent it from rotating.

Improvements in Meat-chopping-machines.
I, WILHELM SCHEFFEL of Remscheid in the Empire of Germany, manufacturer, 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 relates to "Improvements in meat-chopping-machines "and it consists
in the construction of the machine for the purpose of rotating the knife-shaft faster
than the conveyer-shaft and in the construction of the chopping parts themselves.
This improved machine is shown in the accompanying drawing in which
Fig. 1 is a section on line H H of figure 4.
Fig. 2 is a section on line Y Y of same figure.
Fig. 3 shows the cylinder of the conveyer in section.
Fig. 4 is a plan of the machine.
Figures 5 and 6 and 7 and 8 and 9 and 10 illustrate three modifications of the
machine.
Similar letters indicate similar parts in the figures.
The conveyer-shaft d is hollow and surrounds the shaft a rotating the knives in all
the different constructions of my machine shown in the drawing.
In the machine as illustrated by figures 1-4 there is mounted on the one end of the
knife-shaft a spurwheel e and also another one g on the conveyer-shaft d. Both spur-
wheels engage each in another spurwheel f and h, respectively, h and fare mounted
on shaft which may be turned by crank t. These four wheels are made of such a
size that the knives b will rotate faster than the conveyer, as can be plainly seen in
figure 1. By mounting a smaller wheel on shaft a and a larger one on shaft / the
velocity of the knife may be still more increased.
The block c is perforated in a coarser or finer manner according to the fineness of
the pieces to be cut from the meat.
Block and knife are of the same shape as those shown in figure 8 (9' and p).
The construction of the machine shown in figures 5 and 6 varies but little from the
just described one; the spurwheels are changed to friction-disks or wheels, u, m, k;
and shaft l. is set to a right angle to shafts d'and a; the consequence of this is, that
there is needed but one wheel on shaft 1, because wheel m will be rotated faster than
wheel u as the plain of the disk k by which it is turned, is larger in circumference than
that of wheel u, but the velocity of the rotation of wheel m may be still more increased
by mounting disk k and somewhat obliquely to shafts d and a, whereby both
wheels u and m will receive a conical form and wheel m will be accordingly smaller.
The machine shown in figures 7 and 8 is especially adapted for meat which has
many sinews, as this machine cuts the meat three times. On the knife-shaft are
arranged three different knives q, q', q, which cut the meat in connection with the
perforated blocks o and p; knife q runs over block o and knives g' and q³ over
block p.

page_text: Figs. 9 and 10 illustrate a machine where there is done away with the block and
where there are arranged only two sets of knives and s which however are made
rotating in an opposite direction. These knives are provided with notches t¹ on one
side for the purpose of better holding and cutting the meat.
To prevent the meat from sticking to the wall of the cylinder of all the different
modifications of my machine, I have arranged lateral projections n, which always
throw back the lumps of meat on the conveyer.
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) The arrangement in a meat-chopping machine of the cutter-shaft a inside the
conveyer-shaft d for the purpose of rotating the cutters faster than the conveyer,
substantially and in the manner as described.
2) In meat-chopping-machines of the construction specified in claim 1) the arrange-
ment of several knives gliding over perforated disks serving as blocks substantially as
described.
3) In meat-chopping-machines of the construction specified in claim 1) the
arrangement of perforated disks serving as blocks and gliding over stationary knives,
substantially as described.
4) In meat-chopping-machines of the construction specified in claim 1) the arrange-
ment of several knives in two plains rotating against each other and being provided
with notches on the cutting edges substantially and for the purpose as described.
