PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Charging or Discharging Rotatable
Drums, Retorts, and the like.
I, SOHANN CHRISTIAN FELLNER, of Bockenheim-Frankfurt-on-Main, in the
Empire of Germany, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to a device for filling and emptying drums which are
rotatably mounted upon their axes, such for example as are employed for retorts
for the production of ammonia and other products from nitrogeneous substances.
In carrying my invention into practice I provide a drum of cylindrical cross
section which is mounted upon wheels or discs and which may be caused to turn
upon rollers by suitable external driving gear.
The charging and discharging of the drum is effected by means of a screw or
conveyor which is arranged within the retort along the cylindrical wall of the
latter. This screw is continued in one direction to the outside of the retort proper
and passes into a casing, its axis traversing such casing in order to provide for the
operation of the screw in any appropriate manner as for example by means of a belt
and pulley.
The casing is provided with a short flanged tube or branch pipe, radial to the
retort and directed outwards, which tube is in a position for charging or discharging
when the retort has been rotated in such a manner that the screw occupies either
its highest or lowest position, respectively. Then according as the screw is rotated
in such a manner that it is operative in an inward or in an outward direction, the
retort is either filled from a funnel through a pipe and a joint or union or emptied
with the exclusion of the air through a discharge pipe and a union into a movable
receiver which may be run into position on suitable rails.

I, SOHANN CHRISTIAN FELLNER, of Bockenheim-Frankfurt-on-Main, in the
Empire of Germany, 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:―

page_text: This invention relates to a device for filling and emptying drums which are
rotatably mounted upon their axes, such for example as are employed for retorts
for the production of ammonia and other products from nitrogenous substances.
In the accompanying drawing I have shown in side elevation partly in section,
how my said invention may be conveniently and advantageously carried into
practice.
A is a drum cylindrical in cross section which is mounted upon wheels or
discs 7, 7 and which may be caused to turn upon rollers 8, 8 by suitable external
driving gear.
The charging and discharging of the drum is effected by means of a screw or
conveyor 10, which is arranged within the retort along the cylindrical wall of the
latter. This screw is continued in one direction to the outside of the retort proper
and passes into a casing 11, its axis traversing such casing in order to provide for
the operation of the screw from outside in any appropriate manner as for example
by means of a belt and pulley. The casing 11 is provided with a short flanged tube
or branch pipe 12 radial to the retort and directed outwards, which tube is in a
position for charging or discharging when the retort has been rotated in such a
manner that the screw occupies either its highest or lowest position respectively.
Then according as the screw is rotated in such a manner that it is operative in an
inward or in an outward direction, the retort is either filled from a funnel E
through a pipe e and a joint or union e°, or emptied with the exclusion of the air
through a discharge pipe f and a union fo into a movable receiver F which may be
run into position on suitable rails.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is: :-
A rotatable drum provided with a screw or conveyor resting against the inner
wall of the drum for its entire length, and communicating with the exterior through
an addition, which addition when passing vertically upwards above the axis of the
retort enables charging, and when passing vertically below its axis, discharging to
take place, with exclusion of air.
