PROVISIONAL SPECIFICATION.
Improvements in Means Employed in the Manufacture of Hard
Coke, the Distilling of Shale, the Roasting of Ores, or other
Operations wherein Carbonaceous Matter is Subjected to the
Action of Heat.
I LAURENCE HILL ARMOUR of 16 West Street Gateshead-on-Tyne in the
County of Durham Civil Engineer do hereby declare the nature of my said
invention to be as follows:—
My invention relates to means employed in the manufacture of hard coke the
distilling of shale the roasting of ores or other operations wherein carbonaceous
matter is subjected to the action of heat and relates more especially to ovens such
as are described in the Specification of Letters Patent No. 1947 and 5032
of 1882.
According to my invention I supply water or liquid under the charge for instance
under the floor of the aforesaid ovens such water or liquid supply being preferably
led by pipes or conduits which are so laid as to retain a water or liquid seal to
prevent indraught of air. The quantity of water or liquid so supplied may be
regulated by taps or equivalent appliances outside of the oven. By this means the
floor of the oven or place where the gases are led off is kept comparatively cool
and moist and the gases drawn down from the charge are not exposed to the intense
heat to which they would otherwise be exposed and the risk of burning the gases
by air being drawn in through cracks in the structure caused by intense heat is
obviated whilst the gases are drawn off at a temperature lower than would other-
wise be practicable.

COMPLETE SPECIFICATION.
Improvements in Means Employed in the Manufacture of Hard
Coke, the Distilling of Shale, the Roasting of Ores, or other
Operations wherein Carbonaceous Matter is Subjected to the
Action of Heat.
I LAURENCE HILL ARMOUR of 16 West Street Gateshead-on-Tyne in the
County of Durham Civil Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :-
My invention relates to means employed in the manufacture of hard coke the
distilling of shale the roasting of ores or other operations wherein carbonaceous
matter is subjected to the action of heat and products from the charge or heap are
conducted downwards through the charge or heap and relates more especially to
ovens such as are described in the Specification of Letters Patent No. 1947 and
5032 of 1882 and my invention has for its object to provide improved means whereby
the hollow under the floor of the oven or place beneath the charge or heap where
the gases are led off is kept comparatively moist and of the proper temperature for
obtaining the most beneficial results.
According to my invention I supply water or liquid under the charge or heap
(for instance under the floor of the aforsaid ovens) in regulated quantity readily
under control such water or liquid supply being led by pipes or conduits which are
. ለግ

page_text: preferably so laid or made as to retain a water or liquid seal to prevent indraught
of air with the water or liquid. The quantity of water or liquid so supplied may
be regulated by taps or equivalent appliances outside of the floor on which the
charge or heap rests.
I will describe with reference in the accompanying drawings my invention as
applied to an oven of the kind hereinbefore mentioned from which its analogous
applications will also be understood.
Figure 1. of the accompanying drawing represents in vertical section and
Figure 2 in sectional plan an oven provided with means for supplying water or
other liquid in regulated and readily controllable quantity according to my
invention; have shewn two inlets for the water or other liquid delivering into the
space beneath the perforated floor of the oven at two different points one (that
marked By near the outlet pipe for the products and another marked D at some
distance therefrom but I may use but one pipe or several pipes delivering in various
parts under the floor but I prefer at least one pipe to deliver as near to the outlet
for the withdrawal or escape of the gaseous products from the carbonaceous matter
under treatment as is practicable. The pipes Band D are provided with cocks as
at b and ₫ by which the amount of liquid admitted may be readily controlled and
regulated. The quantity admitted should be such that it is all vapourised within
the hollow under the carbonaceous matter under treatment. This may be ascertained
by any convenient means such as for instance by inspection by a plug hole in the
pipe C. The pipes should be so disposed or formed that there is in them a liquid
seal to prevent indraught of air with the liquid and I prefer to arrange the pipes
for instance as shewn at e so that the liquid can be seen as it passes to the hollow
under the carbonaceous matter under treatment constituting in effect a sight feed.
The liquid seal in this case will, of course he between this sight feed and the
inlet for the liquid to the hollow under the carbonaceous material under
treatment.
I prefer to make the pipes where they enter the floor under the carbonaceous
material with a dip inwards and downwards so as to facilitate the carrying out of
the pipes of any dirt or obstruction that may get into them. I may feed in the
liquid continuously or intermittently through the inlet pipes as desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
In ovens or carbonising floors in which products are or may be drawn downwards
through or withdrawn beneath the charge or heap the provision of means as described
whereby a regulated controllable quantity of water or liquid can be fed in beneath
the charge or heap substantially as hereinbefore explained.
