PROVISIONAL SPECIFICATION.
Improved Means and Apparatus for Conveying Incandescent Coke
from Retorts in Gas Works, for Extinguishing same during its
Passage along the Apparatus, and for Screening the Coke, and
Piling up, Storing it, or Discharging it into Wagons or other
Receptacles.
I JOSEPH DE BROUWER, Manager of the Bruges Gas Works, at Bruges
Belgium do hereby declare the nature of this invention to be as follows:-
This invention relates to a gutter or track of metal or masonry laid on the
ground or under ground into which the coke falls after, its discharge from the
retorts.
In this track travel two endless chains connected to each other by iron bars,
said chains being drawn or carried along by toothed wheels or rollers.
A water spray pipe is arranged along or at the side of the track or gutter.
At a certain point of the apparatus situated outside the space necessary for
working the furnaces the track rises at an incline which may be varied according to
local requirements.
At a certain height the track has a sliding grid or grating.
The working of the apparatus is as follows.
The toothed driving wheels gear with the chains and cause them to travel
round drawing the coke with them by means of the transverse connecting bars.
The coke is drawn along and falls out at the end of the gutter track, except the
portion which is screened through the grid, as afterwards explained. At the same
time the water from the pipe in or at the side of the track partly extinguishes the
burning coke all along the gutter and in addition the water which is swept onward
by the coke drawn by the chain up to the point where the track begins to rise
forms an eddy and as it cannot rise up the incline with the coke it pours itself over
the coke entirely extinguishing it.
The excess of water beyond that used for the extinction of the coke remains in
the gutter for the next operation, or runs into a drain which conducts it away.
The workman in charge of the operation has under his control a sliding grid
working in the bottom of the gutter track at a suitable spot. This grid allows the
cinders and coke debris to fall through at the spot chosen for the purpose and by
drawing out the slide the bad quality coke which usually forms at the heads or
mouths of the retorts and comes first can be separated from the rest of the coke
behind it as it travels along.

COMPLETE SPECIFICATION.
Improved Means and Apparatus for Conveying Incandescent Coke
from Retorts in Gas Works, for Extinguishing same during its
Passage along the Apparatus, and for Screening the Coke, and
Piling up, Storing it, or Discharging it into Wagons or other
Receptacles.
: I, JOSEPH DE BROUWER, Manager of the Bruges Gas Works, at Bruges,
Belgium, 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 :-
This invention relates to improved means and apparatus for conveying incan-
descent coke from retorts in gas works for extinguishing same during its passage
along the apparatus and for screening the coke and piling up, storing it, or
discharging it into wagons or other receptacles.
The invention consists of a gutter shaped track arranged in proximity to the
mouth of a coke retort into which the coke can fall when drawn and then be slid
aloug and up the track, be cooled during its travel, and be screened, the screen or
grid being removable for the separation of the inferior body which usually forms
at the mouth and is first discharged.
My invention will be clearly understood by reference to the annexed drawings.
Figure 1, end elevation.
Figure 2, side elevation.
Figure 3, plan.
Figures 4 and 5 respectively are detail plan, and side views of the chain links
and cross bars.
A, is a gutter or track of metal or masonry laid on the ground or under ground,
into which the coke falls after its discharge from the retorts.
In this track travel two endless chains B, B, connected to each other by iron
bars C at intervals, said chains being drawn or carried along by toothed wheels or
rollers D, D.
-
A water spray pipe E is arranged along or at the side of the track or gutter.
At a certain point (say at F) of the apparatus situated outside the space
necessary for working the furnaces, the track rises at an incline which may be
varied according to local requirements.
At a certain height the track has a sliding grid or grating G.
The working of the apparatus is as follows:-
The toothed driving wheels H gear with the chains B and cause them to
travel round drawing the coke with them by means of the transverse connecting
bars C.
The coke is drawn along and falls out at the end of the gutter track, except the
portion which is screened through the grid, as afterwards explained.
At the same time, a supply of water from the pipe fitted in or along at the side
of the track, partly cools down the hot coke, and in addition the water which is
swept onwards by the coke drawn by the chain up to the point where the track
begins to rise forms an eddy, and as it cannot rise up the incline with the coke,
it pours itself backwardly over the coke entirely suppressing the remaining
heat.
The water left after that used for subduing the heat of the coke may remain in
the gutter for the next operation or be run into a drain I which conducts it
away.
The workman in charge has under his control a sliding grid working in the
bottom of the gutter track at a suitable spot. This grid allows the cinders and

page_text: coke debris to fall through at the spot chosen for the purpose, and by drawing
out the slide the bad quality coke which usually forms at the heads or mouths of
the retorts and comes first can be separated from the rest of the coke behind it as
it travels along.
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. Conveying hot coke as it leaves the retort by drawing it along the bottom
and against the sides of a gutter track by cross bars and double chain as described
and substantially as represented by the annexed drawings.
2. In a coke conveyor of the kind above set forth, raising the track gutter for
the drainage and discharge of the coke so raised, as described such as for heaping,
piling up or storing of the coke, or its discharge into wagons or into any other
receptacle.
3. In a coke conveyor of the kiud described, the employment of a removable
grid for screening the coke during its passage along the track and for the free
discharge of the inferior coked material as described.
