1, LAURENCE HILL ARMOUR of 16 West Street Gateshead-on-Tyne in the
County of Durham, Civil Engineer, do hereby declare the nature of this invention
to be as follows :—
My invention relates to ovens furnaces retorts or other structures used in the
making of coke or charcoal or for distilling or roasting carbonaceous matter or
otherwise subjecting carbonaceous matter to the action of heat so that gases are
given off, for instance ovens or the like such as are described for example in the
Specifications of applications for Patents No. 14052 and No. 157991.
The object of my invention is to effect the withdrawal of the said gases without
the mechanical exhausting devices or engine power hitherto employed to work
them. According to my invention I put the pipes or passages by which the said
gases are taken off from the oven, retort, or the like into connection or communi-
cation with the chimney used in connection with the oven retort or the like. or with
any other chimney which may be in proximity to the oven retort or the like and
thus the draught of the chimney is utilized to draw the gases to and through
condensers or to and through other appliances or places in or at which the said
gases are to be treated or utilized.

COMPLETE SPECIFICATION.
Improvements connected with Ovens, Furnaces, Retorts, or other
Structures used in the Making of Coke or Charcoal, or for
Distilling or Roasting Carbonaceous Matter or otherwise Sub-
jecting Carbonaceous Matter 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 invention
and in what manner the same is to he performed to be particularly described and
ascertained in and by the following statement :-
My invention relates to ovens, furnaces retorts, or other structures, used in the
making of coke, or charcoal, or for distilling, or roasting, carbonaceous matter, or
otherwise subjecting carbonaceous matter to the action of heat, so that gases, or
volatile products, are given off (for instance ovens, or the like, such as are described
for example in the Specification of Letters Patent No. 14052 of 1890, and No. 1579
of 1891,) and where it is not required to store permanent gas withdrawn from the
carbonaceous matter under treatment.
The object of my invention is to effect the withdrawal of the gases, or volatile
products, without the mechanical exhausting devices, or engine power, hitherto
employed to work them. According to my invention I put the pipes, or passages,
by which the said gases, or volatile products, are taken off from the oven, retort,
calcining floor, or the like, into connection, or communication, with the chimney, if
one be used in connection with the ovens, retorts, or the like, and if it be suited to
the purpose, or with any other chimney in proximity to the oven, retort, calcining

page_text: floor, or the like, and thus the draught of the chimney is utilized to draw the gases,
or volatile products, to, and through, condensers, or to, and through, other appliances,
or places, in, or at, which the said gases, are to be condensed, treated, or utilized;
for instance, I may cause, by the said draught, the combustible gases, or volatile
products, to be drawn into a furnace, or combustion chamber, by connecting the pipes,
or passages, through which the gases, or volatile products, are withdrawn from the
oven, or the like, with the said furnace, or combustion chamber, which is, in turn, in
connection with the chimney. The uncondensed gases, or volatile products, being
consumed in the said furnace, or combustion chamber, are thereby utilized for
obtaining increased heating effect. Or in place of the uncondensed gases, or
volatile products, being passed into a furnace, or combustion chamber, to be burnt
directly, the pipes, or passages, which lead to the chimney as aforesaid may have
in them, or in connection with them, so that the chimney draught draws the gases,
or volatile products, thereinto, a condenser, or condensers, in which condensation of
the gases, or volatile products, is effected, or a chamber, or chambers, in which the
said gases, or volatile products, are otherwise treated, such as by being subjected
to the action of other gases, or of liquids placed in the said chamber, or drawn, or
sprayed, thereinto from any suitable place to meet the gases, or volatile products,
drawn from the oven, or the like, before they pass into the said furnace, or the like,
or to the said chimney, as aforesaid.
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
In ovens, furnaces, retorts, or other structures, used in the making of coke, or
charcoal, or for distilling, or roasting, carbonaceous matter, or otherwise subjecting
carbonaceous matter to the action of heat, the connection of the passage, or passages,
by which gases, or volatile products, are drawn from the said ovens, or the like,
with a chimney, so that the said gases, or volatile products, are drawn by the
draught of the chimney into the place where they are condensed, consumed, or
otherwise treated, substantially as hereinbefore described.
Dated this 1st day of March 1892.
