Apparatus for Loading Coal and other Friable Materials.
I, HEINRICH KÜPPER, of No. 2 Grabenstrasse, Herne in Westphalia,
Germany, Engineer, do hereby declare the nature of this invention to be as
follows:
My invention relates to an improved construction of apparatus for loading coal
and other friable material into trucks &c. after coming from the depositing and
washing apparatus. This has heretofore been effected by causing the coal coming
From the depositing apparatus, and after discharging the water therefrom, to pass
down over a sieve surface or along one or more shoots into a collecting chamber
from which it is led into the trucks; or it is led directly from the depositing
machine to a transporting channel with appliance for discharging the water, which
conveys it to the collecting chamber for the trucks.
In both cases, owing to the considerable distances through which the coal has to
fall, a breaking up thereof takes place which reduces the value thereof, and
prevents it from satisfying the requirements of the present day as to uniformity in
size of the pieces.
According to the present invention the upward flow or buoyant action of a liquid
is employed to partly counteract the action of gravity upon the coal or other
breakable material, so as to retard the accumulation thereof in the collecting
chamber, and to effect a more careful charging into the trucks.
The materials, such as coal nubbles or nuts, are for this purpose delivered from
the depositing machine, together with the washing water, through shoots into
vertical chambers filled with water, that taper towards the bottom. In these
chambers the coal sinks slowly owing to the buoyant action of the liquid, whereby
the pieces become deposited closely upon each other. During the time that the
coal being charged into these chambers, the displaced liquid flows off over the
upper edges of the chambers into side channels, the chambers being open at top,
and it is partly used for filling a second chamber, while the remainder is led into
the supply tanks for the pumps of the washing apparatus.
The before mentioned shoots are preferably formed branched at the end, so as
to deliver alternately into two of the vertical chambers, suitable valves or flaps
being provided for directing the coal into the one or the other of these, and for
cutting the supply off from both. When the one chamber of a pair is filled with
coal as above described the supply is directed into the other one. In order to
discharge all the remaining water from a chamber when it is filled with coal, the
lower end thereof is constructed with perforated walls through which the liquid
flows off into a surrounding box or trough, from which it is conducted through a
pipe into a channel which leads it to the before mentioned supply tank for the
pumps, the pipe being closed by a valve while the chamber is being filled with
coal. The coal, after the discharge of the water, is conveyed through shoots into
the trucks situated below the lower end of the chamber, which is provided with a
discharge opening closed by a valve or slide.

Apparatus for Loading Coal and other Friable Materials.
I, HEINRICH KÜPPER, of No. 2 Grabenstrasse, Herne in Westphalia, 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:-
My invention relates to an improved construction of apparatus for loading coal
and other friable material into trucks &c. after coming from the depositing and
washing apparatus. This has heretofore been effected by causing the coal coming
from the depositing apparatus or jigger and after discharging the water therefrom,
to pass down over a sieve surface or along one or more shoots into a collecting
chamber from which it is led into the trucks; or it is led directly from the
depositing machine or jigger to a transporting channel with appliance for dis-
charging the water, which conveys it to the collecting chamber for the trucks. In
both cases, owing to the considerable distances through which the coal has to fall,
a breaking up thereof takes place which reduces the value thereof, and prevents it
from satisfying the requirements of the present day as to uniformity in size of the
pieces.
•
According to the present invention the upward flow or buoyant action of a liquid
is employed to partly counteract the action of gravity upon the coal or other
breakable material, so as to retard the accumulation thereof in the collecting
chamber, and to effect a more careful charging into the trucks.
I will describe the improved construction of apparatus for this purpose with
reference to the accompanying drawing in which
Fig. 1 shews a vertical section of the apparatus, Fig. 2 a part plan, and Fig. 3 a
part cross section.
The materials, such as coal nubbles or nuts, are, for the above purpose, delivered
from the depositing machine or jigger a together with the washing water, through
shoots b c d into vertical chambers ef filled with water, that taper towards the
bottom.
In these chambers the coal sinks slowly, owing to the buoyant action of the
liquid, whereby the pieces become deposited closely upon each other.
During the time that the coal is being charged into these chambers, the displaced
liquid flows off over the upper edges of the chambers into side channels, the
chambers being open at top, and it is partly used for filling a second chamber,
while the remainder is led into the sump or supply tanks for the pumps of the
washing apparatus.
The before mentioned shoot b is preferably formed branched at the end as shewn
at Fig. 2 so as to deliver alternately into two of the vertical chambers, suitable
valves or flaps such as g being provided for directing the coal into the one or
the other of the shoots c and d and, if necessary, for cutting the supply off
from both. When the one chamber of a pair is filled with coal as above
described, the supply is directed into the other one, the valve of the latter being
opened while that of the former is closed. In order to discharge all the remaining
water from a chamber when it is filled with coal, the lower end thereof is con-
structed with perforated walls ik through which the liquid flows off into a
surrounding box or trough 1 m from which it is conducted through a pipe n
into a channel which leads it to the before mentioned supply tank or sump
for the pumps, the pipe n being closed by a valve o while the chamber is being
filled with coal. The coal, after the discharge of the water, is conveyed through
shoots st into the trucks situated below the lower end of the chamber, which
is provided with a discharge opening closed by a valve or slide gr.

page_text: 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 :-
In apparatus for loading coal and other friable materials, the use of filling
chambers ef that are filled with water for retarding the descent of the coal or
other material therein, such water being partly discharged by overflow into a
channel at top and partly through a perforated lower part ik of the chamber,
substantially as described.
