Improvements in Apparatus for the Automatic Delivery of Com-
minuted, Powdery, or Granular Materials from Receptacles
Containing the Same.
We, ALBERT WEISS, Engineer, of 180, Limmatstrasse, Zürich, and LOUIS
GIROUD, Engineer, of Bahnhofstrasse, Neue Postgebäude, Olten; both in Switzerland,
do hereby declare the nature of this invention to be as follows:
This invention relates to an apparatus for the automatic delivery of com-
minuted,. powdery, or granular material, such as coal, grain or the like from
receptacles in which the materials are piled up to the desired height.
Beneath the outlet-opening of the said receptacle there is provided, according
to our invention, at a definite distance away, a table which is somewhat larger
than this outlet-opening. On this table rests the material issuing from the
outlet-opening, which material with its peculiar angle of slope spreads itself to
near the edges of the table. If a jolting motion be imparted to the table, the
material runs down at the sides of the table. This automatic delivery of the
material lasts as long as the table is shaken. The quantity of material to be
delivered from the receptacle in any given time can be varied by altering the
shaking motion of the table or by altering the distance of the table away from
the outlet-opening of the receptacle.
In carrying our said invention into practice, we preferably arrange the parts
as follows:
Beneath the outlet-funnel or opening of the receptacle filled up to the desired
height, is arranged a horizontal table which is carried by a frame suspended on
springs. The said table corresponds in form to, but is somewhat larger than the
outlet-opening of the funnel, so that the material with its peculiar angle of slope
issuing from the opening, extends nearly to the edge of the said table.
The shaking motion of the table is effected, for example, by a conveying
channel or chute which is mounted beneath the said table on spring supports and
receives a reciprocating motion in a known manner in order to move onward the
material delivered from the shaking table. On this conveying channel or chute
is mounted a movable, rotary tappet or projection which acts on an arm or pro-
jection on a lever pivotally connected to the frame of the said table. If the
conveying channel or chute is moved to the right, the table is also moved in
this direction, in order that, in the return motion of the conveying channel or
chute, it may be brought back to its original position by its springs. Over the
conveying chute or channel are mounted guide-walls which serve to conduct
the material falling down from the table, safely to the conveying channel or
chute.
In order to enable the table to be brought to rest, whilst allowing the con-
veying channel or chute to continue its shaking motion, the arm or projection on
the pivoted lever can be moved so that it is brought out of reach of the tappet
or projection on the conveying channel or chute. The movement of the said

page_text: arm or projection can, however, only take place if the conveying channel or
chute be also at rest, so that the motion of the conveying channel or chute must
be interrupted for this purpose.
To permit this throwing out of gear of the table to be also effected whilst the
conveying channel or chute continues its shaking motion, the following arrange-
ment can be employed, viz. An eccentric provided with a handle is arranged
in front of the said pivoted lever. By turning the said eccentric through an
angle of 180 degrees, in one direction or the other, the said pivoted lever can
be released or can be turned to one side to such a distance that the tappet or
projection on the conveying channel or chute can no longer act on it. The table
is then at rest and no material is delivered from the receptacle.
In order to be able to regulate the quantity of material to be
delivered from the receptacle, a short length of tube can be mounted in the outlet-
opening of the funnel, which tube can be raised or lowered by means of a suit-
able device in order to adjust the lower opening of the tube to a suitable distance
away from the table and thus alter the cross-section of the free passage between
the outlet-opening and the said table. This effect can obviously be also attained
by correspondingly raising or lowering the said table by means of suitable
devices.

Improvements in Apparatus for the Automatic Delivery of Com-
minuted, Powdery, or Granular Materials from Receptacles
Containing the Same.
We, ALBERT WEISS, Engineer, of 180, Limmatstrasse, Zürich, and Louis
GIROUD, Engineer, of Bahnhofstrasse, Neue Postgebäude, Olten, both in Switzerland,
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 : –
1
This invention relates to apparatus for the automatic delivery of com-
minuted, powdery, or granular material, such as coal, grain or the like from
receptacles in which the materials are piled up to the desired height.
Beneath the outlet-opening of the said receptacle there is provided, according
to our invention, at a definite distance away, a table which is somewhat larger
than this outlet-opening. On this table rests the material issuing from the
outlet-opening, which material with its peculiar angle of slope spreads itself to
near the edges of the table. If a jolting motion be imparted to the table, the
material runs down at the sides of the table. This automatic delivery of the
material lasts as long as the table is shaken. The quantity of material to be
delivered from the receptacle in any given time can be varied by altering the
shaking motion of the table or by altering the distance of the table away from
the outlet-opening of the receptacle.
In the accompanying drawing, Figure 1 is an arrangement of this kind, shown
in vertical section.
Figures 2, 3 and 4 show details of different actuating devices in different
positions.
Beneath the outlet-funnel or opening of the receptacle filled up to the desired

page_text: height, is arranged a horizontal table which is carried by a frame e suspended
on springs d. The said table corresponds in form to, but is somewhat larger
than, the outlet-opening of the funnel a, so that the material with its peculiar
angle of slope issuing from the opening, as shown in Figure 1, extends nearly
to the edge of the said table b.
The shaking motion of the table bis effected, for example, by a conveying
channel or chute k which is mounted beneath the said table on spring supports
and receives a reciprocating motion in a known manner in order to move onward
the material delivered from the table . On this conveying channel or chute is
mounted an adjustable tappet or projection which acts on an arm or projection h
on a levere pivoted upon the bolt or stud f. This lever is pivotally connected
or linked at to the frame of the table b. If in the position of the parts shown
in Figure 1, the conveying channel or chute & is moved to the right, the table b
is also moved in this direction and, in the return motion of the conveying
channel or chute, the said table is brought back to its original position by its
springs d. Over the conveying chute or channel are mounted guide-walls m
which serve to conduct the material falling down from the table b, safely to the
conveying channel or chute.
In order to enable the table b to be brought to rest, whilst allowing. the con-
veying channel or chute to continue its shaking motion, the arm or projection /
on the pivoted levere can be moved so that it is brought out of reach of the
tappet or projection on the conveying channel or chute, as shown in Figure 2.
The movement of the said arm or projection can, however, only be effected
when the conveying channel or chute is also at rest, so that the motion of the
conveying channel or chute must be interrupted for this purpose.
:
To permit this throwing out of gear of the table whilst the conveying channel
or chute continues its shaking motion, the following arrangement, shown in
Figures 3 and 4, can be employed, viz. An eccentric 1' provided with a handle
is arranged in front of the said pivoted lever e. In the position shown in
Figure 3, the arm or projection on the lever e is in its operative position in
which the tappet or projection of the conveying channel or chute can act on it.
If, on the contrary, the said eccentric 1' is turned through an angle of 180 degrees,
in one direction or the other, the said pivoted lever takes up the position shown
in Figure 4. The lever e is thus turned to one side to such a distance that the
tappet or projection on the conveying channel or chute can no longer act on
The table is then at rest and no material is delivered from the receptacle.
In order to be able to regulate the quantity of material to be delivered from
the receptacle, a short length of tube can be mounted in the outlet-opening of
the funnel, which tube can be raised or lowered by means of a suitable device
in order to adjust the lower opening of the tube to a suitable distance away from
the table and thus alter the cross-section of the free passage between the outlet-
opening and the said table b. This effect can obviously be also attained by
correspondingly raising or lowering the said table by means of suitable devices.
it.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. An arrangement for the delivery of comminuted, powdery or granular
material from receptacles, in which arrangement a movable table is arranged
horizontally beneath the outlet opening of the receptacle, which table corre
sponds in form to the outlet opening but is of larger dimensions than the latter
and lies at such a distance beneath the outlet-aperture that the material being
delivered rests on the table at its peculiar angle of slope, and,
in the position of rest thereof, the lower edge of the slope extends close
up to the edges of the table, so that the material, in the reciprocating motion
of the table, runs off at the said edges.
2. In an arrangement such as is hereinbefore described, producing the shaking
motion of the table by the impact of a tappet or projection attached to any

page_text: convenient moving part of the machine, against an arm or projection connected
to the movable table which latter is returned to its initial position by springs,
the said arm or projection being capable of adjustment, at will, to such a
position that the tappet or projection can no longer engage therewith.
3. An arrangement of the kind claimed in the preceding claiming clause, in
which the lever bearing the said arm or projection can be displaced by a cam or
eccentric in such a manner that the said arm or projection is brought out of
range of the tappet or projection acting thereon, substantially as described with
reference to Figures 3 and 4 of the accompanying drawing.
4. An arrangement for the delivery of comminuted, powdery or granular
material such as is herein before described, wherein the outlet aperture of the
receptacle is provided with a vertically adjustable tube which can be moved
towards or away from the table in order to enable the distance between the table
and the outlet opening and therefore the cross-sectional area of the free outlet to
be varied, substantially as described.
5. An arrangement such as is hereinbefore described, in which the table can be
moved towards and away from the outlet opening of the receptacle, in order to
enable the cross-sectional area of the free outlet between the table and the said
outlet-opening to be varied.
