Improvements in Apparatus for Charging Retorts.
A communication from AUGUST KLÖNNE, Machine-builder, of Dortmund, and
FREDERICK BREDEL, of Milwaukee, United States of America, Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention to be as follows:-
The improvement in charging inclined retorts which forms the subject of the
present invention consists in a particular construction of charging machine. The
prominent and novel feature of this improvement consists in the arrangement of
movable discharging gates which enable materials of different degrees of fineness to
be charged. Heretofore great difficulty has been encountered in charging materials
of different angles of repose into an inclined retort such as naturally would be the
case if for instance lump or fine coal have to be charged alternately in inclined
retorts. Lump coal would naturally roll off more easily than coal in a pulverized
state the result would be that lump coal would be heaped up in the lower part of
the inclined retort towards the discharging mouthpiece while fine and moist matter
would naturally not roll down as easily and thereby heap up on the charging end.
This can be obviated by giving the different materials to be charged a different
moment of inertia, providing all the time the retorts are at an angle suitable for the
charging of the finest material under the highest moment of inertia to be obtained
by the foregoing charging apparatus.
If fine material is to be charged one of the gates is opened so as to give the fine.
material a free entrance and high velocity upon leaving the charging hopper and
shoot and when entering the retort.
If coarse or lump material is to be charged another gate is opened so as to cause
the material to change its direction and slide slowly down the lower part of charger
and shoot and enter the retort at a moderate speed. Similar results can also be
obtained with mixed material by partly opening both gates or opening either one
or both completely. If it should be found necessary to charge the retorts heavier
either in front or back or in other words towards the discharging or charging end
of the retorts on account of different heats of retorts this can be effected by suitably
varying the opening of the gates. The apparatus is supplied with the material to
be charged by suitable means and preferably from above. To prevent waste of
material in filling the charger or hopper a funnel is arranged in such a way that it
will not interfere with the charger when the upper retorts are charged. If the
lower retorts are to be charged the material can either drop from the funnel into
the charger or a telescoping arrangement can be made which will prevent the dust
from flying around. The charger can be raised or lowered by suitable hoisting
mechanism. A frame and automatic stops are provided to keep the charger and
shoot in their respective positions to the height of the charging mouthpiece or
opening. The shoot is movable upon a pivot so as to enable it to be adjusted and
admit of the charging apparatus being moved freely on rails in front of the
charging mouthpieces. The charging apparatus may be arranged to hold one or
more charging hoppers and one or more retorts can thus be charged at the same
time. The gates may be made each of one or more pieces.

A communication from AUGUST KLÖNNE, Machine-builder, of Dortmund, and
FREDERICK BREDEL, of Milwaukee, United States of America, Engineer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., 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 improvement in charging inclined retorts which forms the subject of the
present invention consists in a particular construction of charging machine, G, the
particular features of which are shown detailed in Figure 1 and Figure 2;
Figure 3 is a view of the frame supporting the charging machine. The prominent
and novel feature of this improvement consists in the arrangement of the movable
discharging gates H I, which enable materials of different degrees of fineness to be
charged. Heretofore great difficulty has been encountered in charging materials of
different angles of repose into an inclined retort, such as naturally would be the
case if for instance lump or fine coal have to be charged alternately in inclined
retorts. Lump coal would naturally roll off more easily than coal in a pulverised
state, the result would be that lump coal would be heaped up in the lower part of
the inclined retort towards the discharging mouth piece, while fine and moist matter
would naturally not roll down as easily and thereby heap up on the charging end.
This can be obviated by giving the different materials to be charged a different
moment of inertia, providing all the time the retorts are at an angle suitable for the
charging of the finest material under the highest moment of inertia to be obtained
by the foregoing charging apparatus.
If fine material is to be charged as shown in Figure 2 the gate H is opened by a
lever O thus giving this fine material a free entrance and high velocity upon leaving
the charging hopper L and shoot K and when entering the retort B.
If coarse or lump material is to be charged, gate I is opened by lever S as shown
in Figure thereby causing the material to change its direction and letting the
same slide slowly down the lower part of charger L and shoot K and enter the
retort B at a moderate speed. Similar results can also be obtained with mixed
material by partly opening both gates or opening either one or both completely.
If it should be found necessary to charge the retorts heavier or more fully either in
front or back or in other words towards the discharging or charging end of the
retorts on account of different heats of retorts, this can be effected by suitably
varying the opening of the gates H and I. The apparatus is supplied with the
material to be charged by suitable means and preferably from above. To prevent
waste of material in filling the charger or hopper L a funnel M is arranged in such
a way that it will not interfere with the charger L when the upper retorts are
charged. If the lower retorts are to be charged, the material can either drop from
the funnel M into the charger L, or a telescoping arrangement can be made which
will prevent the dust from flying around. The charger L can be raised or lowered
by suitable hoisting mechanism N. A frame X X X X and automatic stops U
engaging with projections are provided to keep the charger L and shoot K in
their respective positions to the height of the charging mouth piece or opening B2.
The shoot Kis movable upon a pivot T so as to enable it to be adjusted and admit
of the charging apparatus being moved freely on rails W W in front of the
charging mouth pieces B2. The charging apparatus G may be arranged to hold one
or more charging hoppers L and one or more retorts can thus be charged at the
same time. The gates H and I may be made each of one or more pieces. Guide
rollers V working against the frame X to keep the charger L in a vertical position,
are pivotted in the projections V.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion as communicated to me by my foreign correspondents, and in what manner the
same is to be performed, I declare that what I claim is :-
1. The combination of the charger provided with independently-movable gates,
a funnel, and a pivotted shoot a frame X clevating devices and catches U substan-
tially as and for the purpose specified.
2. The combination with the frame X and the stops U pivotted thereon of the
vertically-adjustable charger the projections thereon and the rollers journalled in
said projections substantially as shown and described.
