PROVISIONAL SPECIFICATION.
Improvement in Apparatus for Ventilating and Destroying Noxious
Vapours of Drains and Sewers, also Hospitals and other Buildings.
I ALFRED YOUNG Manufacturing Chemist, The Hazelwoods, 137 Holmesdale Road,
South Norwood, in the County of Surrey, do hereby declare the nature of this
invention to be as follows:-
My invention consists of the improvement hereinafter described, viz.: Two
cylindrical cast metal receivers, or chambers, (bell shaped).
First chamber to be made with arched roof or top, with a three inch diameter
flange pipe through the centre of said chamber, standing about three inches high
from the outside of arched roof or crown of said chamber, this said pipe to be
included in the casting.
Second chamber to be made to set or fit to the first arch roof chamber, with a three
inch outside flange joint projecting all round, fastened with nut, and screw bolts,
packed with asbestos between.
Sizo of number one receiver or chamber to be about nine inches in diameter, six
inches high to crown of arch, bottom about four inches diameter, with a three inch
flange joint to be fastened with nut, and screw bolts, with asbestos packing between.
Internal fitting of number one receiver or chamber, is a fireplace with metal
frane having openings (similar to asbestos stoves) fitting close home to sides of said
chamber, resting on a ledge made in the casting, near the bottom part of chamber
in a flat position, with an air-tight fitting door to said fireplace, about four and half
inches long, by three inches high, to attend to gas lighting.
Internal fitting of number two receiver or chamber, is a three inch metal coil,
(similar to still coil) with a flange each end to connect.
Size of number two receiver or chamber to be the same as number one chamber,
excepting the top part which will be about three inches in diameter, with a flange
joint to connect and continue circuit of metal coil up the lamp post or column to
ventilator on top, bottom part of said chamber to have a hole sufficient size to admit
of flange pipe passing through from top or roof of arch of number one chamber.
MAKING UP COMPLETE.
Number one chamber is attached to street sewer, at the four inch flange joint, at
the bottom end, then connect gas, and burner inside asbestos fireplace, of number
one chamber, placing in bed of asbestos, thence fasten flange pipe of uietal coil to flange
pipe of number one chamber at the top, or roof of arch, also place number two
chamber upon the top of number one, and fix flange joints, likewise connect top
end of metal coil flange joint to flange joint of number two chamber, continuing the
metal coil up the lamp post or column to the ventilator at the top, thus completing
the circuit of sewer up draught; or current, being perfectly air tight, except what
comes out from the sewer.
The whole of this apparatus, or sewerage gas destructor is placed inside the base
of the lamp post or column under lock and key.
My said invention has for its object a method for specially ventilating the sewers,
and all such places, is so constructed that a most powerful up current is obtained,
while a most important feature is with this invention, there is no possibility of any
down-draught whatever.
It acts as a perfect destroyer of sewer gas by creating a partial vacuum (by
ntense heat) causing the foul air to rush from the sewer direct up into the bed of
[Price 8d.]

page_text: asbestos fire, thence through metal coil out through ventilator into the atmosphere
thoroughly purified.
Another object is the prevention of contamination of the atmosphere of all large
cities and towns, by the exhalations arising from sewer gas, also to ventilate and
purify the vitiated atmosphere of fever hospitals, &c.
The sewerage gas destructor can be advantageously applied to our present
existing ventilators and manholes as well as to street lamps, thereby consuming all
the poisonous gases which are now diffused into the atmosphere to the great
detriment of the health of the community at large.
The lamp post or column will be so constructed to carry a street lamp on the top,
as well as sewerage gas destructor at the base.
One other most important object in connection with this invention is having the
double chamber service, also the metal coil, one chamber with the asbestos fire,
the other with coil, which has an intense heat, of (400 degrees) so that any germs
of life traversing this inetal coil is instantly destroyed, thus serving, and providing
a double action of decomposition.

COMPLETE SPECIFICATION.
Improvement in Apparatus for Ventilating and Destroying Noxious
Vapours of Drains and Sewers, also Hospitals and other Buildings.
I ALFRED YOUNG, Manufacturing Chemist, The Hazelwoods 137 Holmesdale Road
South Norwood in the County of Surrey, 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 :—
The object of my invention is to extract consume or effectually treat noxious
gases or vapours from drains and sewers or the air during its passage through a
ventilator from the rooms of hospitals and other buildings.
For dealing with noxious gases or vapours from drains and sewers I provide
special apparatus to be fixed below the surface and for ventilating purposes I
provide similar apparatus to be fitted ontside the building to be ventilated and con-
nected with a funnel shaped ventilator protruding within the building through the
ceiling of the room to be vontilated.
In the accompanying drawings Figure 1 is a sectional elevation of the apparatus
for use with drains and sewers and Figure 2 is an elevation of the apparatus as
applied to ventilators for buildings the internal parts being shown in dotted lines.
The apparatus as shown in Figure 1 consists of a bell shaped receptacle divided
into two chambers A and B formed by bolting together the two parts of which the
receptacle is formed, the joint at the junction of the two parts being closed her-
metically preferably by means of an asbestos washer. Into the lower chamber A I
convey a gas pipe with burner C controlled by the stop cock D which may be fitted
in any accessible position not necessarily where the apparatus is fixed.
Within the lower chamber A I place a grid E which serves to support some
refractory material such as asbestos employed in conjunction with the gas fuel to
provide a glowing mass through which the noxious gases or vapours from the drain
or sewer are to pass. Sufficient heat however may be provided by means of gas
burners alone without the intervention of the asbestos.
The furnace thus provided causes an upward current from the drain or sewer the
velocity of which may be regulated by introducing a series of bends in the pipe F
which connects the furnace with the drain or sewer.
The upper chamber B is heated by the furnace created in the lower chamber A and
contains a serpentine pipe G which constitutes the only outlet from the lower
chamber A and may be conducted to any suitable point at which the discharge of the
products of combustion is to be permitted; the most convenient point would generally

page_text: be at the foot of the nearest street lamp post, the hollow column of which would
serve to convey and distribute the same in the surrounding atmosphere.
In the lower chamber A I provide an opening through which the asbestos may be
admitted and close the same hermetically by means of a cover in which I provide
a smaller aperture for examination and lighting purposes capable of being readily
opened and closed hermetically without disturbing the joint of the larger opening.
The operation of the apparatus is as follows:-
The furnace represented by the heated mass of asbestos in the lower chamber A
induces a current of noxious gases or vapours from the drain or sewer passing
through the serpentine pipe F thence through the grid E into the chamber A in
which its temperature is raised to a point at which any organic matter would be
decomposed. The products of combustion arising pass out by the serpentine pipe G
which traverses the upper chamber B several times in its course in order to increase
the time during which the noxious gases or vapours remain under the heating
treatment.
For ventilating purposes I employ similar apparatus as shown in Figure 2 con-
nected with a funnel shaped ventilator H and surmounted by a cowl J which in
conjunction with the serpentine pipe G avoids any down draught.
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 apparatus for treating noxious gases or vapours from drains and sewers the
combination of a furnace chamber A and a heating chamber B with serpentine
inlet and outlet pipes for regulating the passage of the current through the furnace
and the heating chamber and avoiding down draught substantially as described.
2. In apparatus for ventilating rooms of buildings the combination of a ventilator H,
furnace chamber A, a heating chamber B, a serpentine outlet pipe G and a cowl J
for purifying the air passing out from the building through the ventilator substantially
ns described.
Dated this 8th day of August 1890.
