Improvements in Machinery for Sifting, Mixing, and Transporting
Goods of Grainy and Mealy Character.
I EDUARD RULAND-KLEIN of Kalk near Cologne Mechanical Engineer do
hereby declare the nature of this invention to be as follows:-
:-
For separating coals and ores and chemical materials and the like operations it
has been found desirable to have a machine which will be able to do the work of
sifting, mixing and transporting at one and the same time for all three operations
or for any two of them or also each one alone.
The machine invented by me and shown in the accompanying drawings serves
the purpose set forth, and it is also provided with an apparatus, by means of which
it is possible to regulate the efficiency during the working according to the nature
of the material being treated.
The surface upon which the material is treated is, according to the work to be
done, either perforated like a sieve, undulate or in steps, or it is made quite even.
It may be sivelike for the whole length changing only the size of the meshes or
perforations from par to part; part of it may be undulate and part of perforated,
changing in the size of the holes and part of it may be even and solid, that is
without perforations. The frame carrying the working surface therefore may be
constructed as an uniform piece or it may be made in parts connected to each
other by links according to the different parts of which the surface is composed.
The frame is suspended so that it can receive a rocking or swinging movement
making a peculiar way. This movement is caused by au excentric E Fig. 1. The
strap of the excentric is suspended at a point P by means of a rod P A. and at an
other point P' it is fixed to the frame R of the working surface, forcing the
latter to move in a peculiar manner of a curve. Figure 3 shows a diagramm of
such curves.
These curves are larger or smaller, depending of the length of the
excentricity of E; in rising they approach either the vertical direction or they are
more horizontal according to the position of the suspending point A nearer to the
left ende or to the right end K respectively of a scale e¹, d', c², b¹ a, b, c, d, e, f, g,
h, i k.
Accordingly the point P' describes the curves indicated in the direction of the
arrows S, S when the excentric is turned round and consequently also the frame
attached to it, the speed varying in such a ratio that the movement downwards
will be about 2 times as quick as the movement upwards. This is of importance
for the manner of working of my apparatus as will be understood from the
following.
The material brought upon the working surfaces during the first half revolution
of the excentric is thrown upwards in the direction of the arrow S Fig. 3, when
arrived at the highest point the second half of the revolution of the excentric
causes so rapid a downstroke of the frame that the material looses its support and
it therefore continues its way by its own vis viva and falls down at an other point of
the surface, to be ready for a repeated play of same sort.
Each revolution of the excentric therefore auses the advance of the material to
a certain degree according to the shape of the curve.
When it is desired to move the material only forwards such a curve is chosen
that causes the largest advance of the material possible but when sifting and

page_text: mixing is to be done at the same time a curve giving a smaller transporting action
will be chosen. At the same time the frame can be suspended so as to give the
surface a more or less inclined position."
Figures 1, 1 and 2 show a longitudinal and a cross section and a top view of the
apparatus, which also shows working surfaces of different form, i.e. a plain
surface B for transporting the material fed thereon at C, D, a part F made in steps
for mixing and stirring up the material and a part G with perforations like a
sieve for separating the material according to four or three classes respectively.
When the apparatus is closed up in a casing H which is heated either
completely or only at one point 1, or if a current of hot air is blown trough the
material can be heated and dried at the same time. This may be of advantage in
chemical works.
Suspending bars which are supported on small brackets l, m, n serve for
supporting the long frame, they carry the frame which is held on cross bars q, r, s
and coupling rods L transmit the movement.
Figure 4 shows the apparatus as a swinging riddle where the working surface
begins with the smallest perforations or smallest meshes G and ending with those
of largest size of holes at G*.
To each of these partial surface the curved movement corresponding best with
the size of the material upon them, can be given by arranging the brackets l, m, no
adjustable and independently of each other.
As will be understood from Figure 3 the throwing movement can thus be
changed.
The sieves may also be arranged side by side or above one another in a common
frame. The position of the driving shaft K is of no importance for the working;
this will be understood from a glance at Figure 5 showing the apparatus designed
for mixing mainly, whereas Figure 6 shows the same principally arranged for
transporting materials; the surface F of the mixing apparatus instead of being
made uniform troughout may be constructed in groups of different character when
the material to be treated recommends such an arrangement.
The machine may be erected in a horizontal or more or less inclined position,
doors A Figure 6 arranged in the working surface B allow the outlet of material
at those points.
The apparatus described may be used for a variety of purposes because its
construction permits to move it so as will correspond to size or weight of the
material being treated thereon whether this is to be screened and separated or
whether it is mixed or only carried forwards.

Improvements in Machinery for Sifting, Mixing; and Transporting
Goods of Grainy and Mealy Character.
I, EDUARD RULAND KLEIN of Kalk near Cologne Mechanical Engineer
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 :-
For separating ores and coals and chemical materials and the like operations it
has been found desirable to have a machine which will be able to do the work of
sifting, mixing and transporting at one and the same time for all three operations
or for any two of them or also each one alone.
The machine invented by me and shown in the drawing filed with the Provisional

page_text: serves the purpose set forth, and it is also provided with an apparatus, by means of
which it is possible to regulate the efficiency during the working according to the
nature of the material being treated.
The surface upon which the material is treated, is according to the work to be
done, either perforated like a sieve, undulate or in steps, or it is made quite even.
It may be sievelike for the whole length, changing only the size of the meshes or
perforations from part to part; part of it may be undulate and part of it perforated,
changing in the size of the holes and part of it may be even and solid, that is,
without perforations. The frame carrying the working surface therefore may be
constructed as an uniform piece or it may be made in parts connected to each
other by links according to the different parts of which the surface is composed.
The frame is suspended so that it can receive a rocking or swinging movement
making a peculiar way. This movement is caused by an excentric E Fig. 1. The
strap of the excentric is suspended at a point P by means of a rod PA and at
an other point P¹ it is fixed to the frame R of the working surface, thus foreing
the latter to move in a peculiar sort of a curve.
Figure 3 shows a diagramm of such curves. They are larger or smaller depending
of the length of the excentricity of E; in rising they approach cither the vertical
direction or they are more horizontal, according to the position of the suspending
point A nearer to the left end e¹ or to the right end respectively of a
scale e¹ d¹ c¹ b' abcdefghi k.
Accordingly the point P¹ describes the curves indicated in the direction of the
arrows S, S when the excentric is turned round and consequently also the frame
attached to it, the speed varying in such a ratio. that the movement down-
wards will be about 2½ times as quick as the movement upwards. This is of
importance for the manner of working of my machine as will be understood from
the following.
The material brought upon the working surface during the first half revolution
of the excentric is thrown upwards in the direction of the arrow S, Fig. 3; when
arrived at the highest point, the second half of the revolution of the excentric
causes so rapid a downstroke of the frame that the material looses its support
and it therefore continues its way by its own vis viva and falls down at an other
point of the surface, to be ready for a repeated play of same sort.
Each revolution of the excentric therefore causes the advance of the material 'to
a certain degree according to the shape of the curve.
When it is desired to move the material only forwards such a curve is chosen
that causes the largest advance of the material possible, but when sifting and mixing
is to be done at the same time a curve giving a smaller transporting action will be
chosen.
At the same time the frame can be suspended so as to give the surface a more or
less inclined position.
Figures 1, 1 and 2 show a longitudinal and a cross section and a top view of
the apparatus which also shows working surfaces of different form, namely a plain
surface B for transporting the material fed thereon at CD; a part F made in
steps for mixing and stirring up the material and a part G with perforations
like a sieve for separating the material according to four or three classes
respectively.
When the apparatus is closed up in a casing H, which is heated either completely
or only at one point I, or when a current of hot air is blown through, the material
can be heated and dried at the same time. This may be of advantage in chemical
works.
Suspending bars, which are supported on small brackets l, m, n serve for supporting
the long frame; they carry the frame which is held on cross bars 4, r, s and
coupling rods L transmit the movement.
Figure 4 shows the apparatus as a swinging riddle, where the working-surface
begins with the smallest perforations or smallest meshes G and ending with those
of largest size of holes at G 2.

page_text: •
To each of these partial surfaces the curved movement, corresponding best to the
size of the material upon them, can be given by arranging the brackets l, m, n, o,
adjustable and independently of each other.
As will be understood from Figure 3 the throwing movement can thus be
changed.
The sieves may also be arranged side by side or above one another in a common
frame. The position of the driving shaft k is of no importance for the working;
this will be understood from a glance at Figure 5 showing the apparatus designed
for mixing mainly, whereas Figure 6 shows the same principally arranged for
transporting materials. The surface F of the mixing apparatus instead of being
made uniform throughout may be constructed in groups of different character when
the material to be treated recommends such an arrangement.
The machine may be erected in a horizontal or more or less inclined position.
Doors (Fig. 6) arranged in the working surface B allow the outlet of material
at those points.
The apparatus described may be used for a variety of purposes, because its
construction permits to move it so as will correspond to size or weight of the material
being treated-thereon, whether this is to be screened and separated, or whether it is
to be mixed or only carried forwards.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :
1. In a machine for sifting, mixing and transporting goods a frame R carrying a
surface that may be flat, ondulate or perforated for its whole length or of a
compound character, in combination with an excentric E the strap of which is
linked at a point P to a suspension rod P. A, this rod having its fulcrum at an
adjustable point A, whilst a rod P P¹ connects said strap to the frame R.
2. In a machine for sifting, mixing and conveying materials which consists of a
frame R, an excentric E the strap of which is linked at a point P to a rod PA,
the fulcrum point A of said rod being adjustable whilst its other point B is
connected to a frame R by a bar P P, the combination of said excentric with
connecting rods L transporting the movement of the excentric to suspending
bars l, m, n supported by fixed brackets l, m, n and carrying cross bars q, r, son
which rest the various sections B, F, G of the frame R by studs q¹, r, s¹. The
whole as described and illustrated and for the purpose set forth.
