Improvements in Apparatus for Conveying Granular and
other Materials.
I, EUGEN KREISS, of 50 Schauenburger Strasse, Hamburg, in the Empire of
Germany, Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for conveying granular and other materials.
The apparatus hitherto employed for conveying pulverulent and granular
materials, such as the creeper, the helix, the band, the channel which is open at the
top, and the like present the defect of necessitating a considerable amount of driving
power in comparison with their effectiveness by reason of the friction produced in
the necessary bearings and also the friction between the material and the conveying
surfaces proper.
According to the aforesaid invention these defects are obviated by the use of a
closed channel wherein the material is thrown either at an acute angle to the
direction in which it is to be conveyed against two opposite walls or in a straight
direction against special surfaces provided obliquely to the axis of the channel,
whereupon it rebounds approximately at the same angle, so that the material makes
a zig-zag movement, which ensures the most efficient transport with the smallest
amount of driving power. The projection of the material obliquely against a
counter surface is obtained by imparting to the closed channel a reciprocating
movement obliquely to the longitudinal axis of the channel through the medium of
a crank or eccentric. A similar result is achieved by a reciprocating movement
of the channel in the direction of its longitudinal axis or transversely to the same,
in case the walls of this channel are arranged at certain intervals at a proper
inclination.
In case the aforesaid channel is arranged vertically oblique counter-surfaces are
provided in its interior in such a manner that when a rectilineal upward and down-
ward movement is imparted to the channel the material is conveyed upwards to the
outlet. The inlet is stationary and connected with the channel by a flexible hose or
pipe of cloth or canvass in order that the material shall not be thrown out again by
reason of the counter pressure produced.
By means of a channel arranged at an inclination and having a plane interior
surface the material can be conveyed obliquely upwards. To accomplish this object
the channel is suspended or supported by springs placed obliquely to its longitudinal
axis and receives through the medium of a crank or eccentric a reciprocating
upward and downward movement in an oblique direction to that in which the
material is to be transported.
By imparting to a channel arranged horizontally and provided with a plane inner
surface a movement obliquely to its longitudinal axis the material can be conveye]
in the horizontal direction. In this case the channel is suspended by springs
arranged obliquely to its longitudinal axis.
If material is to be transported horizontally by a horizontal channel receiving a
rectilineal reciprocating movement in the direction of its axis or transversely to the
latter it is only necessary to arrange the corresponding opposite sides of the channel
at certain intervals obliquely so as to diverge in the direction in which the
transport is to be effected. A channel constructed in this manner can also be used
for conveying material vertically upwards in case the inlet and outlet are suitably
arranged.
A further advantage of the above-described mode of conveyance consists in the
material entirely filling up the channel during the operation and forming a complete

page_text: column during its transport so that explosions of dust cannot be communicated and
the liability to cause fire is rendered much smaller.
There is also an advantage in the fact that the whole of the material can be
discharged from the channel. This is for instance not the case with the creeper and
the helix, for upon the bottom of their trough always remains a layer of a certain
thickness which gives rise to various inconveniences.
Moreover it will be evident that an increase in the number of revolutions will
result in a greater efficiency of the channel. Accordingly it is of importance that
the inconveniences due to the increased number of revolutions, such as shocks, shall
be obviated. This is accomplished in the most effectual manner by making the
channel as light as practicable, using light flexible cloth for the cover and bottom,
and wood or thin sheet metal only for the lateral walls. Shocks can moreover be
obviated by fixing upon the shaft of the eccentric a counterweight arranged at an
angle of 180 degrees to the latter as in driving wheels of locomotive engines, or a
second eccentric placed at an angle of 180 degrees to the driving eccentric and
adapted to move a weight equal to that of the channel in the opposite direction so
that the channel and weight will balance each other. For the same purpose two
channels can be coupled with each other. Furthermore, the weight of the channel
Can be balanced by a counterweight through the medium of levers or by spring-
power.

Improvements in Apparatus for Conveying Granular and
other Materials.
I, EUGEN KREISS, of 50, Schauenburger Strasse, 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 :—
This invention relates to apparatus for conveying granular and other materials.
The apparatus hitherto employed for conveying pulverulent and granular
materials, such as the creeper, the helix, the band, the channel which is open at the
top and the like, present the defect of necessitating a considerable amount of
driving power in comparison with their effectiveness by reason of the friction
produced in the bearings and also the friction between the material and the con-
veying surfaces proper.
According to the aforesaid invention these defects are obviated by the use of a
closed channel wherein the material is thrown either at an acute angle to the
direction in which it is to be conveyed against two opposite walls or in a straight
direction against special surfaces arranged obliquely to the axis of channel where-
upon it rebounds approximately at the same angle, so that the material makes a
zig-zag movement, which ensures the most efficient transport with the smallest amount
of driving power.
The projection of the material obliquely against a counter surface is obtained by
imparting to the closed channel a reciprocating movement obliquely to the longi-
tudinal axis of the channel through the medium of a crank or eccentric. A similar
result is achieved by a reciprocating movement of the channel in the direction of its
longitudinal axis or transversely to the same in case the walls of this channel are
arranged at certain intervals at a proper inclination.
In the accompanying drawing I have shown how my invention may be con-
veniently and advantageously carried into practice.
Figure 1 represents a section of my improved apparatus arranged vertically.
Figure 2 is a section of the same arranged at an incline and

page_text: Figure 3 is a section showing the apparatus arranged horizontally.
In the form shown in Figure 1 a is the channel or casing provided in its interior
with obliquely arranged counter surfaces to these surfaces are secured to the
channel or casing in such a manner that when a rectilineal upward and downward
movement is imparted to the apparatus as indicated by the arrows the material is
conveyed upwards to the outlet . The inlet c is stationary and connected with
the channel or casing a by a flexible hose or pipe of cloth or canvas in order that
the material shall not be thrown out again by reason of the counter pressure
produced.
Figure 2 shows a modification in which the channel is arranged at an inclination
and the interior surface of which is plane instead of being provided with projections
or oblique surfaces. In this modification the material is conveyed obliquely
upwards. To accomplish this object the channel is suspended or supported by
springs placed obliquely to its longitudinal axis and receives through the
medium of a crank or eccentric a reciprocating upward and downward movement in
an oblique direction to that in which the material is to be transported.
In the modification shown in Figure 3 the channel or casing is arranged
horizontally and is provided with a plane inner surface, the said channel is moved
obliquely to its longitudinal axis so that the material is conveyed in the horizontal
direction, the said channel or casing being for this purpose suspended by springs e e
arranged obliquely to its longitudinal axis.
If material is to be transported horizontally by a horizontal channel receiving a
rectilineal reciprocating movement in the direction of its axis or transversely to the
latter it is only necessary to arrange the corresponding opposite sides of the channel
at certain intervals obliquely so as to diverge in the direction in which the transport
is to be effected. A channel constructed in this manner can also be used for
conveying material vertically upwards in case the inlet and outlet are suitably
arranged.
A further advantage of the above described mode of conveyance consists in the
material entirely filling the channel during the operation and forming a complete
column during its transport so that explosions of dust cannot be communicated and
the liability to cause fire is rendered much smaller.
There is also an advantage in the fact that the whole of the material can be
discharged from the channel. This not the case for instance with the creeper and
the helix as upon the bottom of the trough of such apparatus there always remains
a layer of material of a certain thickness which gives rise to various inconveniences.
Moreover in the present apparatus it will be evident that an increase in the
number of revolutions will result in a greater efficiency of the channel. Accordingly
it is of importance that the inconveniences due to the increased number of
revolutions, such as shocks shall be obviated. This is accomplished in the most
effectual manner by making the channel as light as practicable using light flexible
cloth for the cover or bottom and wood or thin sheet metal only for the lateral
walls. Shocks can moreover be obviated by fixing upon the shaft of the eccentric
a counterweight arranged at an angle of 180 degrees to the latter as in driving-
wheels of locomotive engines, or a second eccentric placed at an angle of 180 degrees
to the driving-eccentric and adapted to move a weight equal to that of the channel
in the opposite direction so that the channel and weight will balance each other.
For the same purpose two channels can be coupled with each other. Furthermore,
the weight of the channel can be balanced by a counterweight through the medium
of levers or by spring-power.
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
claim is:
First. A closed channel, for conveying pulverulent or granular materials, which,
when arranged horizontally or obliquely has projecting surfaces extending in the
same direction as the transport, and is suspended by springs placed obliquely thereto,

page_text: and is supported by them, and receives a reciprocating upward and downward move-
ment obliquely to the direction of the transport, substantially as described.
Second. A closed channel, for conveying pulverulent or granular materials, which,
when arranged vertically is provided interiorly with surfaces placed obliquely to
the direction of the transport and receives a reciprocating movement in the same
direction or when arranged horizontally a movement transversely to the direction of
the transport substantially as described.
