COMPLETE SPECIFICATION.
Charging Machine for Gas-retorts.
I FRANZ GREIN, Engineer of Cologne Ubierring No. 4 II fl. in the County
of Rhineland, 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 :-
The charging of gas-retorts has till now been done by hand with shovel or trough
or mecanically by machines. Most of such machines are however constructed
with a sort of trough which 1° requires a pretty complicated machinery for moving
backwards and forwards, lifting and lowering-especially as the trough in every
position must be kept in balance by counter-weight-2° contains the charge for
only one retort.
This new invention has also for its purpose to effect the charging mecanically
avoids however the application of a trough, thus needing no counter-weight
whatever. It consists of a particularly constructed tank terminating below into
a sideways opened funnel and of a transporter (either endless chain or band or
transport-spiral) placed under the tank. This tank holds the coals for several
retorts at the same time and the transporter conveys to each retort the required
quantity of coals.
The tank is strongly fixed to the transporter and the whole, placed in a movable
frame, can be lifted or lowered by means of crane or other lifting appliance so as
the different heights of the retorts require it. The frame can be so constructed as
to move on wheels on the ground or at the top of the furnace on rails or beams
and it can be carried by hand or machinery in every direction in order to bring
the charging machine before and into each retort and back again.
Fig. 1 shows the coal tank with transporter (here an endless band) in longitudinal
section, Fig. 2 in upper-view and Fig. 3 in cross-section or elevation.
Here the transporter is an endless band constructed of sheet-iron links, connected
by hinges and supported by rollers; these rollers are however not indispensable.
Of course the sheet-iron links can also be bent upwards on the sides, showing
thus an shaped section. Instead of the plates of sheet-metal such of cast-iron
or other metal or fire proof material can be employed. The plates or metal-sheets
can also be enammeled or covered with asbest or any other fire-proof material.
The transporter can also be formed by an endless band made of wire or asbest
net-work or be a transport-spiral.
Fig. 4 shows the apparatus in its movable frame, which runs below on wheels,
the transporter is to its whole length pushed into the retort, thus in action.
Fig. 5 is the half of the other view for a furnace with seven retorts.
Fig. 6 shows the apparatus in a frame running above on beams and entirely
withdrawn from the retort.
Here the bridge-boards of the transporter are supposed to be made of angular
iron whilst in the other figures they are supposed to be of sheet-plates. They can
of course also be made of iron or other material.
When loaded, the apparatus can feed as many retorts in the same hight as it
contains coals for. Therefore it is not necessary to lift and lower the apparatus so
frequently as all other similar machinery requires it, facilitating in this manner the
management and offering great advantages.
The apparatus can be used for every description of retorts.
If the retorts have also a mouth-piece at their back-end the transporter throws
out the coke at the same time when entering into the retort.

page_text: 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 I
claim is :
For gas and other retorts serving for the distillation of solid bodies an apparatus
for charging same consisting of a particularly constructed coal-tank, containing the
charge for one or more retorts, connected with a transporter, which by the funnel-
shaped opening at the bottom of the tank is charged with coal in its whole width
and up to a convenient height and by its movement deposits same uniformly at
first in the back part and then gradually throughout the whole length of the
retort, when withdrawn.
Dated this Fourteenth day of September 1892.
