Improvements in Refuse Consuming Furnaces, and in Means for
Utilizing the Heat therefrom.
I, THOMAS RICHARD BERKLEY, of 83, Collingwood Street, Bethnal Green, Three
Colt Lane, in the City of London, Furnace Man, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in furnaces for consuming the refuse
of towns and the like and consists in the general arrangement of such furnaces
in combination with a boiler for raising steam.
According to my invention the boiler which is of the Cornish type runs longi-
tudinally through the said furnace its lower half being built into the brickwork
of the upper part of the same.
There are preferably four combustion chambers or fire places two on each side
of the boiler provided with hinged doors fastened to the centre bearing bars and
each fitted with inclined fire bars and a hearth behind upon which is fed the refuse
from a charging hole above formed in the top of the brickwork constituting a
charging platform upon each side of the boiler, the said refuse being carried up
to the same by means of machines constructed of girder work or otherwise.
The ash pits are formed with inclined sides and are fitted with blast pipes for
creating a draught regulated by means of valves operated by levers and handles.
The combustion chambers are provided with dampers operated from the charg-
ing platform for connecting or disconnecting the same together and the products
pass therefrom into a main flue running underneath the boiler from whence they
flow to the escape flue or chimney a special swinging damper being provided for
regulating such outflow.
I may also provide an extra small boiler or furnace or both at one or both ends
of the main furnace for the purpose of getting up steam quickly when the main
furnace has been damped down.

page_text: of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to improvements in furnaces for consuming the refuse
of towns and the like and consists in the general arrangement of such furnaces
in combination with a boiler for raising steam.
According to my invention the boiler which is of the Cornish type runs longi-
tudinally through the said furnace its lower half being built into the brickwork
of the same.
There are preferably four combustion chambers or fire places two on each side of
the boiler provided with hinged doors fastened to the centre bearing bars each of the
said chambers being provided with inclined fire bars and a hearth or plate at
the back upon which is fed the refuse from a charging hole above formed in the
top of the brickwork which top constitutes a charging platform upon each side
of the boiler the refuse being carried up to platform by means of an incline or
inclines constructed of girder-work or otherwise.
The ash-pits are formed with inclined sides and are fitted with blast pipes for.
creating a draught underneath the grates and which are regulated by means of
valves operated by levers and handles from the front of the grates.
The combustion chambers are provided with dampers operated from the charg-
ing platform for connecting or disconnecting the same and the products
pass therefrom into a main flue running underneath the boiler from whence they
How to the escape flue or chimney a special swinging damper being provided for
regulating such outflow..
An extra small boiler and furnace may also be provided at one or both ends of
the main furnace for getting up steam quickly when the latter has been damped
down.
Referring to the accompanying drawings Fig. 1 is a side elevation of my im-
proved furnace Fig. 2 is a half cross section through one of the furnaces and
combustion chambers Fig. 3 is a longitudinal section through the said furnaces
on one side of the boiler and Fig. 4 is a perspective view to a small scale showing
the charging platform and inclined approach. a is the brickwork or body of
the furnace into the upper part of which is built the boiler b.
c, c are the
furnaces two on each side of the boiler each fitted with hinged doors d fastene<l
to the central bearing bars e by sliding catches. f are the inclined fire bars behind
which is the inclined plate or hearth g upon which is fed the refuse through the
charging hole formed in the top brickwork or charging platform i and k. Fig. 4
is the inclined way or approach for carrying the refuse up to the said platform.
The ash-pits are each fitted with blast pipes or nozzles m on each side thereof
which are regulated by valves n in connection with the boiler and operated by the
handles outside the furnace for creating a draught in the latter.
The chambers c are each provided with an opening o fitted with a damper o³
operated by chains from outside for connecting or disconnecting the same
and also with an end opening p fitted with a damper operated by a chain p
for regulating the passage of the products of combustion therefrom to the combus-
tion chamber and to the main flue q running underneath the boiler. The main
flue
is continued underneath the ground where it is formed with a dip provided
with an inclined iron ladder and with a swinging door or damper working on a
roller and operated from a chamber above by means of a handle on its pivotal
axis for shutting off the furnaces gases or partly so from the chimney at the end
T
of the main flue.
The flue is also provided with a manhole for cleaning purposes.
The furnace is also provided with the extra small boiler built into the end of
the same and provided with the combustion chamber tash pits and necessary
flues leading to the chimney for getting up steam quickly when the main furnaces
have been damped down. The charging platform is made of the required size
and fitted with the necessary charging holes and dampers and is supported by the

page_text: columns or otherwise so as to give free access to the furnaces for working
the same.
In order to shut off any one of the furnaces from the others or to connect them
for burning their gases I provide a parting damper s which can be lowered from
the platform by hand into the combustion chambers and should any furnace be
required to be shut off for repairs an independent damper or plate is lowered
so as to rest upon the projections in the combustion chamber the damper o being
also closed.
Fig. 4 is a ridge against which the vehicles back for shooting the refuse on
to the platform i and w is the opening in the platform for the boiler b.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
(1). The improved refuse consuming furnace fitted with a steam boiler and
formed with a charging platform and combustion chambers and furnaces fitted
with blast pipes and flues provided with regulating dampers a small boiler being
built-into one or both ends of the main furnace for getting up steam quickly in
the main boiler substantially as described and for the purposes specified.
(2). In refuse consuming furnaces the combination with the main furnace a
of a boiler b furnace or fire chambers e provided with doors d fitted to bars e inclined
firebars and hearths 9 charging holes h formed in a platform i having an in-
clined approach k ash pits / blast pipes m valves n operated by handles n¹ open-
ings o fitted with dampers o¹ operated by chains o and openings p fitted with
dampers p operated by chains 23 a main flue g fitted with a swing damper combus-
tion chambers r dampers r parting dampers s small boiler t provided with combustion
chambers and ash pits platform supports u ridge and opening to substan-
tially as described and for the purposes specified.
