Improvements in Apparatus for Cooling and Conveying Coke
Discharged from Gas Retorts into Suitable Receptacles or
Places.
I, GEORGE WALLER, of Phoenix Engineering Works, Park Street, Southwark,
in the County of London, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object the construction of apparatus for cooling and
conveying coke when discharged from gas retorts into suitable receptacles or places,
thereby reducing much of the labour incidental to such work as ordinarily
carried on.
In order to carry out the invention I make a trough, the top of which is placed
at or below the level of the retort house floor and extends the whole length of the
bench of retorts. If placed below the floor there are openings in the said floor
leading to shoots, the lower end of which terminate in or just above the trough. At
or near each end of the trough there is a drum round which an endless band
composed of metallic plates and supported at intervals on rollers is made to revolve,
motion being imparted to one of the said drums by steam or other suitable power.
The trough is supplied with water so that as the hot coke falls upon the endless band
it is cooled. Sweeps or brushes may be placed on the underside of the endless band
to remove breeze from the bottom of it. Instead of the endless band, an Archimedian
screw or spiral working within the trough may be used to propel or convey the
coke to one end of the trough, when it falls in a chamber adapted adapted to
receive it.
In the chamber just mentioned one part of an elevator is placed, the upper part
of it being at some distance above the retort bench and over a hopper attached
thereto. From the hopper descends a shoot which is capable of being adjusted
laterally by being pivotted to a support like the jib of a crane. Coke thrown into
the hopper will fall down the shoot into trucks or other receptacles placed to receive
it. In order that the coke may be conveyed beyond the trucks and placed at say
the exterior of the retort house the shoot is made in two principal portions hinged
together at appropriate parts of its length.
When the lower part is not in use the outer extremity of it is raised and the coke
falls into the trucks as described, but when used the attendant pulls a lever, when
the outer extremity of it is depressed, at the same time by means of a toothed
quadrant gearing into a rack attached to a slide, the orifice down which the coke
would have fallen to the trucks is closed. A reversal of the action raises the
extreme end of the shoot and opens the orifice just alluded to.
Instead of the coke being delivered at one end of the benches, the endless band
or or spiral may be made in two or more sections, so as to deliver at both ends, or
at any suitable intervening point.

1, GEORGE WALLER, of Phoenix Engineering Works, Park Street, Southwark,
in the County of London, Engineer, 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 has for its object the construction of apparatus for cooling and
conveying coke when discharged from gas retorts into suitable receptacles or
places, thereby reducing much of the labour incidental to such work as ordinarily
carried on.
For the purpose of making the invention easily understood drawings are attached
hereto of which the following is a description.
Fig. 1 is a front elevation of one end of a series of retort benches, and shows the
conveyor, elevator, and shoots.
Fig. 2 is a view of the elevator taken at right angles to that of Fig. 1, and shows
one arrangement of gas engine for giving motion to the machinery.
Fig. 3 drawn to a larger scale shows the conveying trough A, some parts of the
outer plates being removed in order to see the conveyor inside, and
Fig. 4 is a cross section of Fig. 3 and exhibits the trough and conveyor also.
In each of the views similar letters refer to the same parts.
In order to carry out the invention I make a trough A, the top of which is placed
at or below the level of the retort house floor B, and extends the whole length of
the bench of retorts. If placed below the floor there are openings in the said floor
leading to shoots C Fig. 2, the lower ends of which terminate in or just above
the trough. At or near each end of the trough there is a drum D round which an
endless band E conrposed of metallic plates and links, and supported at intervals on
rollers F which run on projections within the trough, and rollers G, is made to
revolve, motion being imparted to one of the said drums by steam or other suitable
power, a gas engine H being depicted in Fig. 2. The endless band and trough
constitute the conveyor proper, although the elevator and further shoots may be
said to be a continuation of it. The trough is supplied with water so that as the
hot coke falls into the shoot or shoots upon the endless band it is coiled. Sweeps,
brushes or scrapers I may be placed on the underside of the endless band to remove
breeze from the bottom of the trough. Instead of the endless band, an Archimedian
screw, or spiral, working within the trough may be used to propel or convey the
coke to one end of the trough, when it falls by a shoot R into a chamber J adapted
to receive it.
In the chamber just mentioned one part of an elevator K is placed, the upper part
of it being at some distance above the retort bench and over a hopper or shoot L
attached thereto. From the hopper descends a shoot M which is capable of being
adjusted laterally by being pivotted to a support N, like the jib of a crane. Coke-
thrown into the hopper will fall down-the-shoot-M-into trucks O, or other
_receptacles-placed-to-receive it. In order that the coke may be conveyed beyond
the trucks and placed at, say, the exterior of the retort house the shoot M is made
in two principal portions M and P hinged together at appropriate parts of its
length. When the lower part P is not in use the outer extremity of it is raised, as
shown in dotted lines, and the coke falls into the trucks O as described, but when
used, the attendant pulls a lever, when the outer extremity of it is depressed, at the
same time by means of a toothed quadrant Q gearing into a rack attached to a
slide, the orifice down which the coke would have fallen to the trucks is closed. A
reversal of the action raises the extreme end of the shoot and opens the orifice just
alluded to.
Instead of the coke being delivered at one end of the benches, the endless band or

page_text: spiral may be made in two or more sections, so as to deliver at both ends, or at any
suitable intervening point.
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,
1. The trough A and conveyor E with their accessories as herein described and
shown on the drawings.
2. The elevator K in combination with the shoot R, chamber J, hopper L and
shoot M as herein described and shown on the drawings.
3. The shoot M consisting of two parts M and P with the support N, and
quadrant Q. and slide arranged as herein described and shown on the drawings.
Dated this 3rd day of January 1891.
