COMPLETE SPECIFICATION.
Improvements in Machines for Cutting or Slicing Sausages and like
Meat Goods and other Substances.
I, WILHELMUS ADRIANUS VAN BERKEL, of 68, Binnenweg, Rotterdam, in the
Kingdom of Holland, Manufacturer, do hereby declare the nature of this invention
and in what manner the same 18 to be performed, to be particularly described
and ascertained in and by the following statement..
In the cutting or slicing machines with 10tary circular knives of spherical
oi conical form described in my previous Patents Nos. 5567 and 25857, good
working is attained by the bevelled part only of the rotating knife being caused
to come in contact with the piece of meat, sausage or the like to be cut, so that the
knife cannot dig into the piece of meat, and cannot become set fast on the cut
surface of the same.
The same good working can be attained according to the present invention
with a flat knife by arranging the said knife so that its axis of rotation is inclined
obliquely to the plane of section of the meat, sausage on the like The knife
then works likewise with the bevelled part only against the piece of meat whilst
the remaining surface of the knife is held away from the piece of meat
In the accompanying drawings, this improved aliangement of the knife is
shown in a machine for cutting sausages and the like pieces of meat, such as
was described in my aforesaid Patents Nos. 55679 and 2585798.
Figure 1 is a side view partly in vertical section,
Figure 2 a plan view partly in horizontal section and
Figure 3 a rear view of the slicing machine.
B is a table for supporting the meat, sausage, or the like to be cut, the ribbed
edge B of wluch table forms the plane of section of the meat. The axis c¹ of
a flat knife C is mounted obliquely to this plane of section, so that only the
bevelled part cl of the knife comes in contact with and acts on the piece of meat,
and all the other parts of the knife do not come in contact with the same This
ax18 C is mounted obliquely in a swinging or Oscillating arm A¹ whilst the
arm itself is moved to and fro in a plane at right angles to the longitudinal axıs
of the table, so that the edge of the said knife shall move closely along the
edge B of the table B. The inclination of the knife to the plane of section of
the piece of meat preferably amounts to 1 in 10.
The arrangement of the oscillating arm A¹ on tunnions Z on the machine
frame R³ and that of the operating mechanism for the rotary knife does not
essentially differ from that described and shown in my aforesaid former patent.
The axis of the knife has here also a conical bearing and the sprocket
wheel T is driven by a sprocket wheel T by means of a chain L. The axis c¹
may be adjusted by means of a sciewed pin 3. The sprocket wheel T is loosely
mounted on an axles and carries a ratchet 3 A pawl carries the sprocket
wheel with it when the arm A¹ 18 pressed down by means of the handle E, that
is to say when cutting and then sets the knife in rapid rotation, the spur wheel
on the shaft s being carried along a toothed segment 7. On lifting the arm A¹

page_text: however the knife is not operated Instead of the pawl arrangement, any other
suitable known arrangement may be adopted by means of which the rotary
knife may be operated In the oblique anangement of the knife axis, the
sprocket wheels must be so arranged that at the side on which the chain 18
stretched, the periphery of the wheel Ti lies in the plane of the sprocket wheel T.
On the other, e, the slack side of the chain, the periphery lies behind the said
plane. A stretching roller which is arranged on the slack side serves at the
same time as a guide roller This arrangement of the knife admits of an oblique
position of the table to the plane of section of the piece of meat.
If, as shown in my Patent No. 5567 the table be movably arranged, the knife
axis and therewith the knife may be mounted obliquely in the rigid frame
of the machine.
It is obvious that in both arrangements a setting fast of the knife in the
piece of meat cannot take place, since the surface of the knife facing the
meat does not come in contact with it. In consequence of the inclined or oblique
position of the knife, the cut off discs or slices of meat or sausage or other sub-
stance are not cut flat but slightly bent, but owing to the softness of the material
this 18 not of any moment. On the other hand the arrangement has the advantage
that the knife by reason of its flat form can be more easily and more cheaply
made than the spherical or conical knives before refered to.
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 improvement in machines for cutting or slicing sausages and like meat
goods and other substances, of the kind having a revoluble cucular knife, which
consiste in giving the knife a flat form and mounting it obliquely to the plane
of section of the substance being cut or to the edge of the table substantially as
herein before set forth
2 The improved cutting or slicing machine constructed and operating as a
whole substantially as herein before described and illustrated
