Improvements in Coke-extinguishing or Quenching and Loading
Apparatus.
I, FRANCIS JOSEPH COLLIN of Dortmund in the German Empire, 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 :-
If incandescent coke is suddenly immersed in water, and soon after taken out
of it, the result is a beautifully brilliant silver-like material, owing to the fact
that the interior of the lumps of coke continues hot, so that the water entering
them is immediately evaporated again. In the hitherto usual process of con-
veying the coke to the point of discharge or delivery and then extinguishing it
by means of water-jets, the doors and side walls of the coke-furnaces are
unavoidably damaged sooner or later; and that process also has the drawback of
allowing the coke to burn away to a large extent before the extinguishing
operation can commence, which results in materially reducing the output.
To obtain the advantage of an immediate, nay sudden, cooling and at the
same time avoid the inconveniences attending the old extinguishing method, the
coke is in the manner more fully described further on received by a travelling
band or apron, which carries it, through water, to the point of discharge or
delivery.
The apparatus in the form shown in the accompanying drawing contains a
water reservoir A into which the coke gradually drops, and from which, after
being extinguished, it is conveyed further on by the endless chain band B.
This band is driven by a pitch-wheel the speed of which may be regulated by
means of step pulleys so that the rate of the extinction of the coke may be
regulated to suit requirements. From the carrier band the coke falls upon a
shaking or rocking sieve S operated by suitable machinery whereby it is sifted
and sorted, the fine coke and cinders falling into a hopper T, while the bigger
lumps slide down into a waggon or truck arranged to receive them.
For separating the finer lumps such as "coke-breeze" from the dust or cinders
a further inclined sieve may be arranged at the bottom of the hopper T under-
neath the main vibrating sieve S, so that the dust falls through, and into the waggon
below, and the small lumps are discharged on the side.
The lower end of the sieve S may be turned up out of the way and lowered over
the truck to discharge its contents.
The whole of the apparatus is arranged to travel along a quay or raised platform
and may be fitted for operation by either hand or steam.
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. A combined coke extinguishing and delivering apparatus in which the
incandescent coke as it issues from the furnace is collected conducted through water
and by means of an endless band or carrier conveyed to the truck or waggon.
the sorting into sizes and the separation of the coke-dust being performed as the
coke travels to the delivery end substantially as described.
2. In coke quenching and loading apparatus the employment as part of the
apparatus of a water tank into which the incandescent coke is discharged substan-
tially as described and illustrated in the accompanying drawing.
3. In coke quenching and loading apparatus the combination with a tank such

tially as described and illustrated in the accompanying drawing,
4. In coke quenching and loading apparatus the combination in the same
travelling apparatus of a coke quenching tank a conveyor and sifting apparatus
substantially as described and illustrated in the accompanying drawing.
