Device for Cutting Onions to Pieces, and for Preventing the Sharp
Exhalations of the same from Affecting the Eyes.
I, FRANZ PRETZEL, of 32, Grosse Hamburger Strasse, of Berlin, in the
Kingdom of Prussia, German Empire, Manufacturer do hereby declare the nature
of this invention to be as follows:-
This invention relates to a device for cutting onions to pieces, and the object of
my invention is to effect that cutting in such a manner, that the eyes of the
respective person are prevented from being affected by the sharp exhalations of the
onion, whilst the latter is cut.
I attain this object by the device shown in the accompanying drawing, in
which similar letters denote similar parts throughout the different views, and in
which:
Fig. 1 shows an outer view of the device,
Fig. 2 a vertical section through the same, and
Fig. 3 a horizontal section, taken on the line 4-5 of Fig. 2.
The device consists of a casing a, which is open at its bottom, and closed at its
top, and which contains a cross-like knife b, that is held by, and fixed to, a rod c.
This rod may be moved upwards and downwards, as well as turned, and is guided
by a short tube a' secured to the fixed cover a¹ of casing a.
The onion to be cut to pieces is placed on a wooden board, and is covered then
by casing a, whereafter the cross-knife is moved onto and into the onion as many
times as requisite for cutting the same to the required smallness of pieces. The
exhalations arising during this time are perfectly kept back within the casing, so
that they cannot affect the eyes.
Dated this 26th day of February 1894.

Device for Cutting Onions to Pieces, and for Preventing the Sharp
Exhalations of the same from Affecting the Eyes.
I, FRANZ PRETZEL, of 32 Grosse Hamburger Strasse, of Berlin, Kingdom of
Prussia, German Empire, 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 :-
This invention relates to a device for cutting onions to pieces, and the object of
my invention is to effect that cutting in such a manner, that the eyes of the
respective person are prevented from being affected by the sharp exhalations of
the onion, whilst the latter is cut.
I attain this object by the device shown in the drawing sent in with Provisional
Application, in which similar letters denote similar parts throughout the different
views, and in which:

page_text: Fig. 2 a vertical section through the same, and
Fig. 3 a horizontal section, taken on the line 4-5 of Fig. 2.
The device consists of a casing a, which is open at its bottom, and closed at its
top, and which contains a cross-like knife that is held by, and fixed to, a rod c.
This rod may be moved upwards and downwards, as well as turned, and is guided
by a short tube a secured to the fixed cover a' of casing a.
The onion to be cut to pieces is placed on a wooden board, and is covered then
by casing a, whereafter the cross-knife is moved onto and into the onion as many
times as requisite for cutting the same to the required smallness of pieces. The
exhalations arising during this time are perfectly kept back within the casing, so
that they cannot affect the eyes.
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. As a device for cutting onions to pieces, and for hindering the sharp
exhalations of the same from affecting the eyes, the combination with a casing
adapted to be put over the onion to be cut, of a knife arranged within said casing,
and adapted to be driven into the onion from the outside of the casing, substantially
as described.
2. As a device for cutting onions to pieces, and for hindering the sharp
exhalations of the same from affecting the eyes, the combination with a casing
adapted to be put over the onion to be cut, of a knife arranged within said casing
at a rod extending upwards through the cover of said casing, and being adapted to
be operated by said rod, substantially as described.
3. As a device for cutting onions to pieces, and for hindering the sharp
exhalations of the same from affecting the eyes, the combination with a casing
adapted to be put over the onion to be cut, of a cross-like knife secured within said
casing to a moveable rod extending upwards through the cover of said casing, and
being adapted to be lowered and raised, as well as turned by said rod, substantially
as described.
