I WILLIAM SCOBLE, Foreman of Gas Works, Bow Common Lane, Mile
End, do hereby déclare the nature of the said Invention for. "ARRANGING
THE RETORTS, FURNACES, FLUES, COMMUNICATIONS, AND CONNECTIONS, FOR. THE MORE
ECONOMICAL MANUFACTURE OF GAS, AND BY WHICH ARRANGEMENT THE GENERATIVE
HEAT MAY BE OBTAINED FROM EITHER COAL; COKE, TAR; OR- OTHER SIMILAR COM-
BUSTIBLE SUBSTANCES," to be as follows:-

.
As in the accompanying Drawing, in this we have shown. a pair of upper
and lower through benches for a more particular purpose of. showing the
advantages of the manufacture of gas for large towns, increasing colonies,
but which same principle may be applied to small towns, and even to private
mantifactories with advantage.
-
It consists of this, referring to Drawings and letters as follows: Let us
suppose the retorts, (as for a large establishment.) to be arranged in pairs of
upper. and lower through benches, which may be extended as may be required.
The peculiarity of my Invention is this:-
-
First, we remove the underneath furnaces entirely, which leaves room for

page_text: the introduction of more retorts; and place the furnace on the top of the
benches, and conduct the draft downwards to the underneath flues, which
communicate with the main shaft. The benches may be built single or double
and in continuous lengths, as may be required; they are run up with piers,
arches turned, faces built, forming hot-air furnace chambers or cellars, through
which the heat may circulate in any way we may require by placing fines and
dampers in such places as may be found most advantageous.
A. A. represents the brickwork for a pair of double through benches; B, B,
shew the position in which the retorts may be placed (and are shown so for
illustration). they may be of any shape and any length. I have shown ten
retorts in the upper chamber, which is floored over, and I have shewn six
retorts in the lower, and I build a counterpart the other side, which I call a
pair of double through benches.
My Invention is this, I place the retorts C and C in the position usually
occupied by the furnaces, and place the furnaces on the top of each pair of
double through benches, and conduct the draft downwards to the underneath
flue, which communicates with main shaft in the following manner, or assimi-
lating to it, as circumstances or position will allow..
For an example, we show thus, D. D, are a pair of furnaces, which may be
built in the form most suitable for the combustible substance used to generate
the premitive heat, and which is herein claimed as one and the same thing
as my arrangement of retoris, furnaces, flues, &c., and which is more fully
explained hereunder,
First, the furnaces D and D are placed on the top and between each pair
of double benches, and must be proportioned according to the length and
number of retorts used.
. These furnaces are built in pairs where double retorts or retort of extreme
length, say from 18 to 30 feet, are used, and the heat is drawn into a longitu-
dinal flue, marked E, E, running along the centre of each bench, and then
brought down through the openings marked F, F, F, as may be shown in
this my illustration. The flues F, F, F, lead into the upper retort chamber G,
where I allow the heat to accumulate, and then draw it off through the
passages H, H, H, which are arranged so as most effectively to draw off
retain, distribute, and circulate the heat, and bring the same into lower
chamber, where it remains until it is found advantageous. to allow it to
descend into the flue leading to main shaft.
I claim as my novelty and Invention, this my method of placing the furnaces
above the retorts, and the drawing the heat downwards and accumulating and

page_text: retaining the same in the different retort chambers that may be required,
and also by which arrangement any combustible substance may be used to
obtain the premitive heat.
The advantages obtained by this my method are the more equitable
distribution of the heat, whereby the cracking of the retorts is prevented,
gas of a superior quality is generated, an equivalent of coke, tar, &c., is
obtained, and with a considerably less consumption of fuel than by the ordinary
