EDWARD SERGEANT 5 Stephenson Terrace Preston in the County of Lancaster,
M.R.C.S. L.R.C.P. Lond. Lic. San. Sc. do hereby declare the nature of this invention
to be as follows:―
My furnace known as the incenerator has become extensively used for dealing with
refuse at infectious diseases hospitals and elsewhere and steam disinfectors have also
been extensively used for the disinfection of clothing.
The object of this invention is to utilize the products of combustion from a furnace
burning refuse to assist the process of disinfection by steam in a simple combined
apparatus.
My invention consists in the combination of the two, with certain detail additions
necessary to form a complete installation for refuse burning and steam disinfection.
The furnace may be constructed in accordance with my invention known as the
incenerator, or in other convenient form and the disinfector may be constructed in
accordance with any apparatus used for the production of disinfection by means
of steam.
To construct the combined refuse furnace and disinfector in accordance with this
invention, the flue passing out of the furnace is carried forward into a firebrick
chamber which is constructed to partly surround the steam disinfector, by this means
the heat contained in the products of combustion from the refuse is brought to bear
upon the outside shell of the steam disinfector, thus utilizing the heat by generating
steam and also forming a warm jacket to the disinfector.
When the refuse is not sufficient to produce all the steam and heat needed for
disinfection, ordinary fuel may be fed upon the fire grate.
If desirable a steam generator may be placed in the flue leading from the furnace
to the disinfector similar to those boilers employed in connection with refuse destructors,.
but this is no part of my invention, as steam has already been produced in this way.
The steam produced may also be used to sterilize excrementitious matter or sewage
from infectious hospitals.

Combined Apparatus for Burning Refuse and Disinfecting.
EDWARD SERGEANT, 5 Stephenson Terrace Preston M.R.C.S., L.R.C.P., L.S.Sc.,
do hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
My furnace known as the incinerator has become extensively used for dealing with

page_text: refuse at infectious diseases hospitals and elsewhere and steam disinfectors have also-
been extensively used for the disinfection of clothing.
The object of this invention is to utilise the products of combustion from a furnace-
burning refuse to assist the process of disinfection by steam in a simple combined
apparatus.
My invention consists of the combination of the two with certain detailed additions
necessary to form a complete installation for refuse burning and steam disinfection.
The furnace may be constructed in accordance with my invention known as the
incinerator or in other convenient form, and the disinfector may be constructed in
accordance with any apparatus used for the production of disinfection by means
of steam.
To construct the combined refuse furnace and disinfector in accordance with this
invention the flue passing out of the furnace is carried forward into a firebrick chamber
which is constructed to partly surround the steam disinfector by this means the heat
contained in the products of combustion from the refuse is brought to bear upon the
outside shell of the steam disinfector thus utilizing the heat by generating the steam
and also forming a warm jacket to the disinfector."
When the refuse is not sufficient to produce all the steam and heat needed for
disinfection ordinary fuel may be fed upon the firegrate.
If desirable a steam generator may be placed in the flue leading from the furnace to
the disinfector similar to those boilers employed in connection with refuse destructors
but this is no part of my invention as steam has already been produced in this way.
The steam produced may also be used to sterilise excrementitious matter or sewage
from infectious hospitals.
In order to more clearly explain my invention I illustrate it by the accompanying
drawings.
Fig. 1 is a sectional elevation of the combined refuse furnace and disinfector:
Fig. 2. is a plan of the combined apparatus:
Fig. 3. is an end view showing the arrangement of the fittings.
Like letters represent like parts in each figure.
a represents the furnace mouth for feeding the refuse furnace with ordinary fuel
and also for drawing on the refuse out of the cavity & upon the firebars c.
refuse is fed into the furnace through the hopper d and received on the cavity band
is acted upon by the products of combustion from the fire on the firebars c and is
also acted upon by the heat reverberated from the firebrick arch e. The products of
combustion then pass through a flue on to the disinfecting chamber f: this chamber
is surrounded by a jacket g forming a space between the two shells which is filled
with water up to the line A and this water being acted upon by the heat passing
round the flues į steam is thus generated and the top part marked è forms a steam
space the height of water is shown in the water-gauge . Afterwards the products
of combustion pass down the flue m which has a damper 'n to regulate the burning
of the refuse and the generation of steam: afterwards they reach the chimney o and
then pass away into the atmosphere. A door is provided for cleaning out the bottom
of the chimney at p and there is also a door q for cleaning out dust passing from the
refuse furnace before entering the flues passing round the disinfecting chamber. The
arrangements for feeding the boiler are similar to what are usually employed for
feeding steam boilers and a safety valve is provided at so that steam will blow
off when the required temperature for disinfection is obtained. There is also
provision for cleaning out the disinfector casing through mud holes and a blow off
valve.
The ends of the disinfecting chamber are fitted with doors marked so arranged
that the goods may be put in through the door at one end and discharged into
another room when disinfected through the opposite door.
From the above arrangement it will be seen that the heat produced from burning
refuse will generate steam in the lower part of the disinfecting chamber between the
inner and outer shells and the top part between the inner and outer shells forming
a steam space provides steam to be used inside the chamber for disinfecting purposes.

page_text: I thus get a combined arrangement which will be found useful and economical in
dealing with infectious materials. It will be seen that ordinary fuel may be used
for disinfecting goods when the supply of refuse may have run short.
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:
The combined arrangement of refuse furnace and disinfector substantially as
described and illustrated."
