Mechanism for Disintegrating and Mixing Powder-like Materials.
I, HERMANN DIETZ of Gustav Adolphstrasse, Leipsig 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 :-
Many powder like materials for instance flour cement colour stuffs or coal dust
easily ball together in receptacles where they are placed and often block the outlet
openings. It will therefore be convenient to arrange the outlet opening so that
larger or smaller lumps are let through and can be loosened in their passage. In
the present machine this is obtained by the arrangement whereby the outlet
openings can be enlarged or diminished during the working by means of a
slide and whereby also the unequal material is poured out on a shaking plate
which moves with an adjustable stroke against the circumference of a brush
roller.
In the annexed drawing Fig. 1 is a vertical section Fig. 2 an elevation Fig. 3 is
a plan view, of a hopper with mechanism of this principle Fig. 4 illustrates a
modified construction Fig. 5 is a detail view.
The outlet of the funnel T is formed on one side by the slide S, Fig. 1, which
can be moved by means of several toothed segments Z. or the like fixed upon the
cominon shaft W3 in Fig. 2 and on the other side by the surface of the shaking
plate R, which is guided by the shaking arm A against the brush roller B. The
shaking plate R is hinged on the funnel T at y and is curved at its free end so
that it surrounds a part of the circumference of the roller brush B, so that all the
material, which leaves the funnel through the outlet opening, must pass for a
considerable distance between the roller brush B and the shaking plate R. In this
way still remaining lumps are loosened by means of the quickly working brush and
mixed with the other material.
The shaking plate R receives its movement from the shaft W' Figs. 2 and 3, by
means of the shaking arm A engaging lugs X on the shaking plate. The move-
ment of the shaking gear and thus also of the shaking plate is made variable by
the arrangement, whereby the lever arm, Fig. 3, of the shaft W' on which operates
the draw rod P is arranged for a variable leverage. By this variability of the
movement of the shaking plate it is made possible to avoid any obstruction during
the working.
The construction shown in Fig. 4 with double outlet opening serves for mixing
powder like or granular materials of different size of grain or of different specific
weight or of otherwise different condition and for the mixing of clotted and of
unclotted material. For these purposes the machine comprises divided funnels T'
and T2, which pour into a common receptacle. The position of the slide is arranged
for each of the two funnels according to its material and to the quantities which are
to be mixed from each of the two materials. Each of the two materials is thus
wiped away from the shaking plates in the proportion of the desired mixture of
quantities by means of the brush rollers S1 and S2 and both currents of the
materials, Fig. 4 are thrown to cross one another so that they fall well mixed into
the conveyor E.
By brush roller I do not mean only a cylindrical brush which is provided on its
whole surface densely with bundles of bristles, fibres wires etc., but also cylindrical

page_text: brushes, the bristle bundles of which are at certain distances from one another as
in the upper part of Fig. 5 or cylindrical drums, which are provided on their
surface with small plates or straps of leather, india-rubber, metal or the like, as in
the lower part of Fig. 5.
For the purpose of loosening and good distribution of the materials, the
shaking plate may be ribbed or roughened so far as it surrounds the brush,
or ribbed or roughened surfaces are arranged on the shaking plate at this place.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) Improved mixing machine for powder like materials in which the outlet.
opening pours upon a shaking plate R, which surrounds partly with its free end a
roller brush B.
(2.) Improved mixing machine for powder like materials in which the shaking
plate R is moved against the circumference of the brush roller by the shaking
arms A which are fixed on the common shaft W¹ and receive from the outside an
adjustable movement.
(3.) The construction of the mixing machine as in Claim 1 with double delivery
funnels (T and T2 Fig. 4) and two mixing devices, which empty two materials to
be mixed together in a crossing direction into a common receiver for the purpose of
mixing in any proportion of quantity two powder like materials which are different
from one another in the size of their grains or in their specific weight or
otherwise.
(4.) The construction of the mixing machine as in Claim 1 in which the free
end of the shaking plate R is ribbed or roughened or is provided with ribbed or
roughened covering.
