page_text: When the coal in the retorts is carbonized the valve n on the gas pipe m is
closed. The airtight mouthpiece is then removed from the door and the coke
withdrawn. Another charge of coal is then introduced either through the
aperture at the top of the retort or through the door & and the airtight mouthpiece
and the covering of the aperture (k and 1) replaced and the roasting or carbonising
of the charge goes on.
The regulator n on the gas pipe m is now opened and the liberated gases and
bye products from the heated charge of coal in the retorts actuated by a partial
vacuum or by the pressure of the gas or by both in the retorts pass out of the
retorts or closed ovens by the pipe m through a water sealed joint and are then
dealt with in any convenient manner common to the usual practice with such like
products.
The arrows shew the course of heated gases from the coke ovens.
Figure 6 is a horizontal section through the second arrangement of ovens and
retorts.
Figure 7 is a sectional elevation on line ABCD of Figure 6.
Figure 8 is a front view (one half in section) of the coke ovens.
Figure 9 is a sectional elevation on line G H.
In these figures a a a &c. are the coke ovens in which coal is carbonized and its
volatile constituents mixed with a judicious quantity of air which takes the form
of gas and becomes incandescent, this gas is allowed to escape through. suitable
apertures bbb &c. governed by regulators into a flue or chamber ccc &c. thence
through apertures d d d &c. governed by regulators it is made to pass into. the
retort chambers E E E &c. (in which ordinary gas retorts 9 9 9 &c. are fixed in
the usual way and around which it plays) and thence by means of passages hh.h. &c.
(where it can again be regulated and governed by regulators) into the main
flue iii &c. and passing thence be further utilized for other objects on its way to
the chimney.

In the drawings retorts are shewn in four only of the chambers.
Assuming the work to be in operation shortly the process is this:-When the
coal in any of the coke ovens à a a is sufficiently carbonized the damper in the
aperture 6 may be closed and the coke withdrawn and another charge of coal
introduced the door jis then walled up or closed and the coal will in all probability
take fire from the heat of the previous charge or from that of the neighbouring
ovens (if not it will have to be assisted in the usual way by fire) on this taking
place the damper 6 (if closed) is opened to allow the gas to escape and a suitable
quantity of air is admitted into the ovens from the outside through suitable holes
'so as to consume the gases arising from the heated coal and to facilitate.its-carboni-
zation these gases becoming incandescent and actuated by a partial vacuum. pass
from the oven through the apertures bbb &c. and is coursed by means of regulator
dampers through the retort chambers E in which are set the retorts.
When the coal in the retort is carbonized the airtight mouthpiece K is removed
and the coke withdrawn and another charge of coal is then introduced and the
airtight covering replaced and the roasting or carbonizing goes on the gas.and bye
products passing up the pipes m through a water sealed joint and dealt with in the
common manner.
The arrows shew the course of the heated gases.
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. The combination of a series of coke ovens and a series of retorts approximately
at the same level and with a receiving flue or chamber between them and flues
fitted with dampers by which heated gases from the receiving flue-or-chamber can
be led around the exterior of the retorta and to an exit- flue, substantially as
