PROVISIONAL SPECIFICATION.
Improvements in Mixing, Kneading, and similar Machines.
A communication from PETER KÜPPER, of Aix-la-Chapelle, German Empire.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent do hereby declare the nature of this invention to be as
follows:-
The stirring or mixing apparatus is especially intended for use in connection
with machines for kneading dough; it, however, may also be employed in conjunc-
tion with other similar machines in which various materials are submitted to
treatment of a kindred nature.
Owing to the arrangement of transversely or radially extending arms and
transversely or radially extending blades at about the centre of the wings, the
material is thoroughly worked in a circular direction, across the machine, while
the spiral bending of the outer limiting plates mounted on the arms and the
corresponding spiral shape of the blades cause the material to be thoroughly mixed
in a direction parallel to that of the axis of the machine, the material being in this
case moved in the direction paralled with the axis.
The material may be further stirred, kneaded and mixed in the lateral direction
(but still parallel to the axis of the machine) by further symmetrically bending the
ends of the outer plates at an angle to the planes of the radii, which principle may
be applied also to the central plate if required.
Dated this 9th day of March 1893.

COMPLETE SPECIFICATION.
Improvements in Mixing, Kneading, and similar Machines.
A communication from PETER KÜPPER, of Aix-la-Chapelle, in the German
Empire.
I, ALFRED JULIUS BOULT, of 323, High Holborn in the County of Middlesex,
Chartered Patent Agent, 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 :—
The stirring or mixing apparatus illustrated in the accompanying drawings is
especially intended for use in connection with machines for kneading dough; it,
however, may also be employed in conjunction with other similar machines in which
various materials are submitted to treatment of a kindred nature.
Owing to the arrangement of the arms A B C and blades D E F at about the
centre of the arms, the material is thoroughly worked in a circular direction, across
the machine, while the spiral bending of the outer limiting plates or stops a b and c
of the arms and the corresponding spiral shape of the blades def cause the
material to be thoroughly mixed in a direction parallel to that of the axis of
the machine, the material being in this case moved in a direction parallel with
the axis.
The material may be further stirred, kneaded and mixed in the lateral direction
(but still parallel to the axis of the machine) by further symmetrically bending the
ends of the outer plates or arms A B at an angle to. the planes of the radii, which
principle may be applied also to the central plate or arm c if required,

page_text: Having now particularly described and ascertained the nature of the said inven-
tion (as communicated to me by my foreign correspondent) and in what manner
the same is to be performed, I declare that what I claim is :—
A stirring or mixing apparatus characterized by
1. Three arms such as A B C arranged symmetrically on the shaft of the
machine, the outer limiting plates of which are spirally bent.
2. Three blades such as D E F of spiral shape arranged symmetrically on the
axis, one opposite the middle of each of the arms A B C substantially as described
and illustrated in the accompanying drawings.
Dated this 10th day of October 1893.
