Improvements in the Means and Apparatus for Conveying Hot Coke
Direct from the Retorts of Gas Houses and other Plant and Deposit-
ing the same in the Stores.
I, MAURICE GRAHAM, of Black Bull Street, Leeds, in the County of Yorkshire,
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:-
The invention relates to improvements in the means of conveying hot coke
direct from the retorts of gas houses and other plant and depositing the same
in the stores.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawings thereof reference being had to letters
and figures marked thereon.
Fig. 1, is the longitudinal section through the drawing stage of a retort house,
and through the water trench i in which the conveyor marked a is placed. On
the outside of the building, the lattice braced casing b shews the method of
elevating the coke up to its storage, delivering from the coke conveyor on to
an ordinary storage conveyor c, this drawing is shown cut in two.
Fig. 2, a cross section through a retort house, shewing one of these conveyors
placed at either side of the drawing stages.
Figs. 3, and 34, is the plan of Fig. 1.
Fig. 4, cross section through the trench and conveyor drawn to an enlarged
scale.
Fig. 5, is the trailing end s arrangement.
Fig. 6, the driving end t of the conveyor.
Fig. 7, is an alternate arrangement in transverse section through the trench i
and conveyor in which I construct a splayed shaped castings 7 which are longi-
tudinally fixed on each side and adjoining the top of the trench by means of
long bolts with washers and nuts. The object of the aforesaid castings are
to form the hopper to guide the material in the trays g.
Fig. 8, is a plan of the splash plate or shield n.
Fig. 9, is an end elevation of the splash plate mounted with wheels to run
on rails 2 attached to a drop bracket 3 bolted to the transverse girder 4.
Fig. 10, is a side elevation of Fig. 9.
The improvement consists in the running of the conveyor in a trench i of
water, the trench i being provided with longitudinal hinged door plates d.
The conveyor a consists of two endless pivoted bands of steel link work e, with
suitable attachment links f, to which is attached the pressed steel trays g. In
every alternate link will be placed a roller h, supported on axle j, which is bent
to support and strengthen the tray.
On and obout every tenth plate will be rivetted a strong angle iron m for
cleaning out the coke smudge from the bottom of the pit, and conveying it
through the sluice valve into the sump 7. The top tray and rollers will be
supported from the sides of the pit by means of tee irons, and on the return
side it will be supported on similar rails secured to the foundation.

page_text: The scetion of the trench i will be of the form shewn on Fig. 4, or in Fig. 7,
the sides and bottom being formed out of cement slag, with channel iron guard
plates over the wheels secured thereto, the top being built over into the forni
of a hopper. The door plates, when open, will be as represented in Fig. 2.
There will also be provided a special improved form of splash plate or shield n,
this splash plate will be mounted on rollers, and will be capable of running
from end to end of the bed, and will be of such proportions as to guide the
coke into the conveyor from, one bed.
The splash plate or shield n is constructed of sheet iron plate on three sides
with an angle iron frame 5. On each of the three sides I mount wheels 6 loosely
mounted on brackets 7. Rivetted to the base of the drop brackets 3 on each
side are the rails 2 on which the wheels 6 move with the splash plate or shield.
To each traneverse girder 4 opposite every backstay 1 is fixed a bracket 3.
The object of the sump is that the coke sludge will be conveyed by means of
angle irons m into this sump, which may be, when desired, shut off from the
main trench by means of the shuice valve k, allowed to settle and drain, and
after being cleaned out may be opened for further use.
The conveyor a rises at its end b, and delivers the coke on to the distributing
conveyor c. The rising part b is a trough of the lattice braced type, and by
thus raising the end of the conveyor out of the water, it has the advantage of
delivering the coke direct on to the conveyor c, without the intermediate use
of an elevator.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:
1. In an apparatus for conveying hot coke direct from the retorts of gas
houses and other plant and depositing the same in the stores, the combination
and arrangement of the longitudinal water trenches i hoppers g sump 1 sluice
valve k doors d and the conveyor a lattice braced casing b storage conveyor_c
splash plate n with the trailing end s and driving end t, substantially as herein
described and according to the accompanying drawings.
2. In an apparatus for conveying hot coke direct from the retorts of gas
houses and other plant and depositing the same in the stores, the combination
and arrangement of the trays g endless bands e attachment links f rollers h
axles angle irons m rails o trailing end s, and driving end t, substantially as
herein described and according to the accompanying drawings.
3. In an apparatus for conveying hot coke direct from the retorts of gas
houses and other plant and depositing the same in the stores, the combination
and arrangement of the water trench hoppers g bolts r and hinged doors d,
substantially as herein described and according to Fig. 7, of the accompanying
drawings.
4. In an apparatus for conveying hot coke direct from the retorts of gas
houses and other plant and depositing the same in the stores, the combination
and arrangement of the various parts substantially as fully described in the
above specification and illustrated on the accompanying drawings.
5. In a splash plate or shield, the combination and arrangement of the three
sides and the angle iron frame 5 brackets 7 wheels 6 rails 2 and drop brackets 3
bolted to the transverse girders, substantially as herein described and according
to the accompanying drawings.
