PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Feeding Gas Retorts.
I, CHARLES DENTON ABEL, of Birkbeck Bank Chambers, Southampton Buildings,
Chancery Lane, in the County of London, Consulting Engineer and Chartered
Patent Agent, do hereby declare the nature of this invention (as communicated
to me from abroad by the Société Anonyme Continentale Pour la Fabrication des
Compteurs a Gaz ct Auties Appareils, of 9, Rue l'étrelle, Paris, France,) to be
as follows
-
This invention relates to apparatus for feeding gas retorts with coal
For this purpose the coal is raised by an elevator and delivered on to a conveyor
which leads it along a horizontal trough situated above the range of retorts and
provided with openings over each vertical line of retorts, these openings having
slides to close them. On rails under the trough runs a funnel truck having a
slide to close its bottom opening and carrying by chain and pulleys the scoop for
feeding the retort When a retort requires to be fed, the funnel truck is run to
a position over the mouth of the retort and is filled through the opening in the
conveyor trough The scoop, being then adjusted to the height of the retort, is
charged by opening the bottom of the funnel, and the charge is carried by the
scoop into the retort and deposited therein.
If the conveyor takes more coal along than is required, the surplus is delivered
at the end of the tough and taken back to the elevator. The surplus may be
rendered very small by adjusting the speed of the conveyor to the demands of
the retorts The chain of the conveyor may be arranged to return along the floor
under the retorts so as to receive and convey the coke raked from the retorts.
Instead of arranging the funnel truck to run on rails under the conveyor trough,
the funnel may be mounted on a wheeled frame running on rails on the floor.

I, CHARLES DENTON ABEL, of Birkbeck Bank Chambers, Southampton Buildings,

to me from abroad by the Societe Anonyme Continentale Pour la Fabrication des
[Price 8d 1

page_text: Compteurs a Gaz et Autres Appareils, of 9, Rue Pétrelle, Paris, France) and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement.-
This invention relates to apparatus for feeding gas retorts with coal.
For this purpose the coal is raised by an elevator and delivered on to a conveyor
which leads it along a horizontal tough tuated above the range of retorts and
provided with openings over each vertical line of retorts, these openings having
slides to close them. On rails under the trough runs a funnel truck having a
slide to close its bottom opening and carrying by chain and pulleys the scoop for
feeding the retort When a retort requires to be fed, the funnel truck 18 1 un to
a position over the mouth of the retort and 18 filled through the opening in the
conveyor trough The scoop being then adjusted to the height of the retort, 18
charged by opening the bottom of the funnel, and the charge is carried by the
scoop into the retort and deposited therein.
If the conveyor takes more coal along than is required, the surplus is delivered
at the end of the trough and taken back to the elevator. The surplus may be
rendered very small by adjusting the speed of the conveyor to the demands of
the retorts The chain of the conveyor may be arranged to return along the floor
under the retorts so as to receive and convey the coke raked from the retorts.
Instead of arranging the funnel truck to run on 1ails under the conveyor trough
the funnel may be mounted on a wheeled frame running on rails on the floor.
The said apparatus is shewn on the accompanying drawings in which Figure 1
shews a front view and Figure 2 a cross section thereof A A¹ is an endless travel-
ling conveyor of any suitable known construction, which receives the coal at the
one end B from a chain bucket elevator C C and which works in a fixed casing a
provided at distances apart corresponding to that of the retorts, with trapdoors D.
A hopper E of a capacity corresponding to the quantity for one or more charges
can be run along angle iron rails in the casing a underneath the conveyor; the
discharge opening of this hopper can be closed by a pivoted flap b. A charging
scoop C is guided and supported by a roller g on a suspending chain R, as will be
presently explained while situated under the discharge opening of the hopper E, as
shewn at Figure 2. The hopper serves the double purpose of conducting the coal
from the trap doors D into the charging scoops G and also for gauging each charge
for the scoop so that only the exact required quantity is introduced, the discharge
into the scoop taking place as this is gradually pushed forward into the retort.
The conveyor receives a continuous motion, while the trap doors D are opened
intermittently as may be required When the charging hopper has been filled and
the particular trap door D closed, the coal continues to be carried forward by the
conveyor to the end A', and is there discharged into a shoot H which conducts it
into a receptacle on wheels at F by which it is again run back to the elevator.
The speed of the latter is so regulated as to reduce the quantity of this excess
of coal supply to a minimum.
The scoop 18 suspended from the hopper E by means of the chain R of a differ-
ential pulley by which it can be raised and lowered so as to be brought to the level
of whichever retort requires to be charged
The chain has a loop through which the scoop can be slid and it is provided
with a roller 9 on which the scoop rests for facilitating such motion.
The above described feeding apparatus can also be so arranged as to serve at the
same time for receiving and conveying away the spent coke discharged from the
retorts, as shown in the elevation at Figure 3. For this purpose the returning 5
part of the chain conveyor A A¹ is arranged to pass downwards at the point A¹
to the level of the floor, so as to receive the coke discharged from the retorts: the
convevor is in this case extended sufficiently beyond the retort house at the feeding
end to allow of the coke being discharged from the lower part thereof while passing
up the shoot z, before receiving a fresh charge of coal from the elevator CC¹.
Instead of supporting the moveable hopper E and scoop G on rollers running
in the casing of the conveyor as described these parts may be mounted on a travel-
5

page_text: ling frame K running on rails M on the floor of the retort house as shewn in front
view at Figure 4, side view at Figure 5, and plan at Figure 6.
The frame K 18 brought successively under each of the trap doors D of the casing
of the conveyor A for charging these retorts which lie in the same vertical line
with the trap door
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:-
1 Apparatus for feeding gas retorts consisting of the combination of a conveyor
which carries the coal along in front of the retorts with a moveable hopper arranged
to receive a definite charge of coal from the conveyor, and to discharge such coal
directly into a charging scoop below as this is slid forward into the retort, sub-
stantially as described
2 In apparatus for feeding gas retorts such as is referred to in the first claim,
suspending the charging scoop from the hopper by means of differential pulley
gear arranged to guide the scoop correctly under the discharge opening of the
hopper and to bring it to the desired level for charging the different retorts,
substantially as described.
3 In apparatus for feeding gas retorts such as is referred to in the first claim,
ananging the returning part of the conveyor to serve also for receiving and con-
veying away the coke discharged from the retorts, substantially as herein described
with reference to Figure 3 of the drawings
