PROVISIONAL SPECIFICATION.
An Improved Knife for Slicing Sugar-beets, Sugar-canes,
and the like.
I, RUDOLPH BERGREEN of Roitzsch near Bitterfeld, German Empire, Manufacturer,
do hereby declare the nature of this invention to be as follows:-
My improved has for its object to slice sugar beets, sugar canes and the like in
such a manner that the slices become more uniform in size and thickness and prevent
specially sugar beets from loosing their juicy properties, when being cut up, also to
provide a knife with an edge longer lasting than the usual knife heretofore known
and used for the purpose.
According to my invention I provide the knife which is placed in the usual manner
on an iron plate and then inserted in the cutting box in the machine used for the
purpose of cutting such materials for manufacturing purposes, with a toothed or jagged
edge like a straight toothed saw or similarly shaped. Whereby I attain the advantages
previously mentioned.

COMPLETE SPECIFICATION.
An Improved Knife for Slicing Sugar-beets, Sugar-canes,
and the like.
I, RUDOLPH BERGREEN of Roitzsch near Bitterfeld, Germany, Gentleman 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 apparatus and contrivances for cutting in slices beet, turnip,
sugar cane and the like and is fully explained in the following Specification and the
drawing herewith. The letters of reference in the Specification referring to like
letters on the drawings. In Fig. 1, 2, and 3 the construction of knife or cutter
according to my invention is shewn and consists of a metal plate B, the edge of which
is cut out in zig-zag fashion, forming pointed cutters (Fig. 1) or square cutters p
(Fig. 2), by the former producing triangular by the latter square slices. Fig. 3 is a
section of Fig. 2 on the line o-0. The knife B can now be employed in various
manners either singly or in combination, and in Fig. 4 it is shewn held in a frame A
and in combination with a second plain knife. In this instance the knife B is
placed at an angle relatively to the bed o on which the beet etc. to be cut would
be placed, while in Fig. 6 the knife is placed horizontally with the plane side o
of the knife facing upward.
Fig. 5 is a ground plan view of Fig. 4, and Figs. 7 and 9 are sections of Fig. 5
on the lines M-M. and N-N. respectively, with a beet in course of being cut
shewing the action of the knives B and C, as do also Figs. 8 and 10.
Fig. 11 shews the combination of two knife frames A, and in which the knives
are placed with their cutting edges at a small distance from the cutting edge k of
bed G.
Fig. 12 is a broken ground plan of same, while Fig. 13 is a section of Fig. 11

In Fig. 14 & 15 is shewn a machine in which the principle above explained is
adopted, numerous knives B and C being fixed in a frame A, the knives C being
adjustable in clamps which can be tightened by means of nuts m.
attached to knife frame A, gives the latter a see-saw motion, being actuated in the
usual way from crank E and eccentric F, Fig. 14 representing the frame A in its
most distant position relatively to the eccentric F and Fig. 15 representing it in its
nearest position relatively to the said eccentric F. When sugar cane is required to
be sliced by means of this machine it is fed into same by means of an endless
belt J and passed through feed rollers M and L into the machine, a board H,
turnable on hinge i and pressed down either by means of a spring or weight or
better by a roller K adjustable in its bearing h, serving to force the cane against
the knives.
In Fig. 16 and 17 a similar machine is shewn but provided with a hopper N in
which the beet to be sliced is thrown, the letters of reference being the same as in
Figs. 11, 14, and 15.
It will be readily seen that in either machine the slices drop through the bottom
and are afterwards collected in any suitable manner.
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 I
claim is :-
1. A knife for producing slices of beet, sugar cane and the like, consisting
essentially of a solid metal plate, the edge of which is cut in zig-zag fashion, pro-
ducing points and p and indents s (Fig. 1 & 3) such knives being attached to cutting
frames of machines either singly or in combination with plain knives C, all sub-
stantially as described and shewn in the drawings.
