An Improved Method of and Apparatus for Separating Liquids from
Solid Materials.
I, CHRISTIAN EUGEN KREISS, of 34, Papenstrasse, Hamburg, in the Empire of
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:
-
The characteristic feature of this improved process of draining is, that, by
means of an oscillatory conveying gutter or channel (shaking gutter), the
material to be drained is carried along in an inclined upward direction, while the
water flows off rearwardly.
The draining apparatus itself consists of a gutter or channel arranged in an
inclined position, for instance supported by or suspended from connecting rods.
and provided with a double bottom, the upper one of which being perforated and
the lower one closed; the said draining apparatus being moved to and fro by
means of suitable gearing.
The material charged with water and intended to be drained is supplied at
the lower end of the channel or gutter, where it is placed on the upper hase, said
upper base being perforated, open worked or provided with a sieve-fabric, is
then conveyed upwards by a corresponding movement of the gearing and leaves
the other end of the gutter or channel in a condition free from water, whilst the
water flows back and through the perforated surface and is returned to the inlet
along the closed base in order to be either removed by means of another conduit
Thus
or to be again supplied to the in-flow or feed end in any suitable manner.
in the latter case the water used, partakes of a circulating motion, a fact which.
apart from the saving of water, offers the advantage, that no loss of disintegrated
material. which would be otherwise carried away, is caused.
The solid material is caused to ascend the inclined draining trough by arranging
the supporting rods or the like at an oblique angle to the bottom of the trough
and by giving to the said trough, in consequence of this arrangement, a recipro-
cating motion not parallel to its longitudinal axis but somewhat oblique to the
latter, so that the trough receives an oblique up-and-down or slightly inclined
reciprocating swinging motion whereby the material is thrown upward and for-
ward and is caused to creep or bound along in the said trough. From the above
it follows that the friction between the material and trough-bottom is greater
during the forward and upward stroke than during the backward and downward
stroke of the trough. since the latter stroke takes place whilst the material is
being thrown upward and is practically not in contact with the trough bottom
and is consequently more or less prevented by this fact as well as by the vis
inertiae of the material from partaking of the backward motion of the draining
trough. As soon as the material comes again in contact with the trough bottom
another forward and upward impulse is given to the said trough and also to the
material contained therein in order to cause the said material to advance anew
by bounds or leaps.
The oscillating mechanism such as connecting rods may be either arranged to
move on hinges, or so as to yield under spring action or may be substituted by
roller hearings. guide rails, or, in case of the apparatus being suspended, by
chains ropes and the like.
Instead of the upward movement of the material being effected by the oblique
position of the connecting rods, the same may also be effected by forming the
unner or perforated base sten-shaped.

the same may on the contrary, be partly closed; moreover the lower base may
be so constructed, as to only extend over a portion of the whole channel or gutter
and may even be entirely omitted, in which case the water would flow down
directly. Under certain conditions it may, in the case of treating material of
a somewhat coarse nature, he sufficient, to only provide the gutter or channel
with one upwardly inclined closed base, upon which the material is carried along
upwards, while the water flows off in backward direction.

An Improved Method of and Apparatus for Separating Liquids from
Solid Materials.
I, CHRISTIAN EUGEN KREISS, of 34, Papenstrasse, Hamburg, in the Empire of
Germany. 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:―
The characteristic feature of the improved process of draining is, that by
means of an oscillatory conveying, gutter or channel (shaking gutter). the
granular. pulverulent or like material to be drained is carried along in an inclined
upward direction, while the water flows off rearwardly.
The draining apparatus itself, illustrated in the accompanying drawing in longi-
tudinal vertical section consists of a gutter or channel b arranged in an inclined
position, for instance supported by (or suspended from) spring or other connecting
rods d, and provided with a double bottom, the upper one c¹ of which being
perforated and the lower one 2 closed: the said draining apparatus being moved
to and fro by means of a suitable driving gearing for instance by means of an
eccentric cam.a¹ and a connecting rod a.
The solid material placed, unon the inclined draining trough is caused to
ascend the latter by arranging the supporting rods or the like at an oblique angle
to the bottom of the trough and by giving to said trough, in consequence of this
arrangement, a reciprocating motion not parallel to its longitudinal axis but
somewhat oblique to the latter, so that the trough receives an oblique up-and-
down or slightly inclined reciprocating swinging motion whereby the material
is thrown upward and forward and is caused to creep or bound along in the said
trough. From the above it follows that the friction between the material and
trough-bottom is greater during the forward and upward stroke than during the
backward and downward stroke respectively of the trough, since the latter stroke
takes place whilst The material being thrown upward is practically not in contact
with the trough bottom and is consequently more or less prevented by this fact
as well as by the nis inertiae of the material from partaking of the backward
motion of the draining trough. As soon as the material comes again in contact
with the trough bottom another forward and upward impulse is given to the said
trough, and also to the material contained therein in order to cause the said
material to advance anew by bounds or leaps.
The material charged with water, and intended to be drained, is supplied at
the lower end of the channel or gutter, where, it is placed on the upper base c¹,
said upper base being perforated, or provided with a sieve fabric, is then con-
reyed upwards by the swinging or reciprocating motion of the gutter, and leaves
the other end of the gutter or channel in a condition free from water, whilst the
water flows back and through the perforated surface c¹ and is returned to the

of another conduit e or to be again supplied to the inflow or feed end in any
suitable manner. Thus in the latter case the water used partakes of a circulating
motion, a fact which, apart from the saving of water, offers the advantage, that
no loss of disintegrated material, which would be otherwise carried or washed
away, takes place."
The apparatus which I have described may be used for draining purposes proper
i.e. for separating water or moisture from the material fed along in the inclined
draining trough, or it may be used for washing purposes or it may be used
even for lixiviating purposes, the same water being then employed over and over
again. The apparatus may therefore be used for all purposes or processes in
which a separation of the water or liquid mixed up or contained in the material
to be operated, is intended or desired; this separation by means of an inclined
shaking gutter, as well as the improved gutter itself, forms the main feature of
the present invention.
The oscillating mechanism such as the connecting or supporting rods d may
be either arranged to yield under their spring action, as shown in the drawing,
or so as to move on hinges, or they may be substituted by roller bearings, guide
rails, or, in case of the apparatus being suspended, by chains, ropes and the
like.
Instead of the upward movement of the material being effected by the oblique
position of the rods d the same may also be effected by forming the upper or
perforated base step-shaped.
It is not necessary that the upper base c¹ be perforated throughout its length,
the same may on the contrary, be partly closed; moreover the lower base may
be so constructed, as to only extend over a portion of the whole channel or gutter
and may even be entirely omitted, in which case the water would flow down
directly. Under certain conditions it may, in the case of treating material of
a somewhat coarse nature, be sufficient, to only provide the gutter or channel
with an upwardly inclined closed base, upon which the material is carried along
upwards, while the water flows off in backward or downward direction.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is: -
1. The improved method of separating moisture from granular, pulverulent
or like material which consists in conveying obliquely upwards the material to
be freed from moisture by means of a swinging channel or gutter (shaking trough),
whilst the water or moisture thereby separated flows or drops back, substantially
as and for the purpose set forth.
2. In an apparatus for separating moisture from materials the combination of
a channel or gutter (shaking trough) having a perforated bottom, said channel
being arranged in an inclined position and supported or suspended by rods,
springs or the like, of a separate collecting gutter beneath the perforated bottom,
and of a suitable driving device adapted to impart to the said trough a reciprocating
swinging motion, substantially as and for the purpose described.
