PROVISIONAL SPECIFICATION.
An Apparatus for Preventing the Escape of Smoke or Noxious
Fumes from Chimneys.
I JOSEPH TERTIUS WOOD of Butts Chambers Civil and Mining Engineer
Rochdale in the County of Lancaster do hereby declare the nature of this inven-
tion to be as follows:-
My invention relates to an apparatus applicable to furnace flues for preventing
the escape of smoke and noxious fumes into the atmosphere, which may arise
during the combustion of coal, coke, or other fuel. My invention has for its object
to divest the smoke of its soluble gases or noxious waste products by means of
precipitation.
According to my arrangement. I provide and adapt any convenient part of the
flue of an ordinary mill boiler-preferably the part terminating at or near to the
entrance of the chimney shaft-as a spray chamber the same being composed of
specially prepared material such as glazed fire brick, concrete, or other suitable
material such chamber being composed in segments, or in whole, and being
preferably of greater sectional area than the flue or flues. The walls of the said
chamber may be solid in thickness or may be provided with cavities, in either case
of construction sprinklers are provided in connection with the sides or walls of the
chamber, from which, water, steam, or any suitable liquid which may be found
convenient to combine with the component gases of the smoke, may issue under
pressure, and supplied from a convenient source of supply. The spray is so
arranged as to traverse the whole area of the chamber and to thoroughly saturate
or wash the smoke issuing to the chimney, and may be regulated in quantity or
force to suit the rate of travel of the smoke to the chimney, which will vary
according to the draught, and to be capable of dealing with a volume of smoke
more or less dense, and to precipitate the same in a convenient form on the floor of
the spray chamber, which floor is arranged to incline and to have a falling gradient
for a convenient distance in the direction of the chimney the lower part of the
incline terminating with a drain provided with a syphon or bent orifice in which is
contained a column or body of water capable of resisting a maximum pressure
which may be exerted by the draught of the chimney, thus a back draught in the
flue may be obviated, at the same time the condensed gases precipitated on the floor
of the spray chamber may be allowed to escape out through the drain to any
convenient place as may be desired.

COMPLETE SPECIFICATION.
An Apparatus for Preventing the Escape of Smoke or Noxious
Fumes from Chimneys.
I JOSEPH TERTIUS WOOD of Butts Chambers Civil and Mining Engineer
Rochdale in the County of Lancaster 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 :-
This invention relates to an apparatus applicable to and adapted for use in
connection with furnice flues by which means and by the method or process adopted
and carried out by this arrangement the escape of smoke or noxious gases or

page_text: fumes may be prevented from passing out of the chimney or exit flue into the
atmosphere.
The principle of this invention consists in the precipitation of the noxious fumes
or gases by means of a solvent such as water or other suitable liquid media which
solving media may be applied so as to treat or deal with the smoke and to intercept
the same between the furnace flue and the exit flue or chimney.
In order that a clear understanding of my invention may be had I have in order
to facilitate the explanation thereof annexed hereto a sheet of drawings showing a
longitudinal sectional elevation thereof.
In accordance with my construction I provide at any convenient part of the
flue a so as to intercept the said flue and the chimney ba chamber c which I term
"spray chamber" the spray chamber being constructed or faced with non-absorbent
or non-porous material such as glazed brick, cement &c., being so constructed in
order to resist moisture thus avoiding what is known as a "damp, or green flue" as
would be the case where water is used and were non-absorbent materials not used.
The said chamber I preferably construct of greater area than the flue the bottom
or floor of which is inclined at the lower side of which I provide a sump d com-
municating with an exit drain intercepted by a syphon f. Within the chamber
is arranged any convenient number or series of spray tubes or sprinklers g made of
suitable material, which sprinklers are connected with a water or other source of
supply under pressure, steam &c. being so arranged with relation to the chamber
as to thoroughly search or drench the smoke passing through the whole area of the
chamber thus the smoke issuing from the flue through or into the chamber to
the chimney may be thoroughly saturated or impregnated with moisture and the
sulphurous or soluble gases may be precipitated on to the floor of the chamber in a
liquid form and flow to the sump thence through a column of water provided in the
syphon out to the exit drain.
The syphon being provided with a column of water capable of resisting and in
order to resist the maximum force which may be exerted by the air current in the
chimney thus a back current in the flue may be obviated at the same time the
condensed or soluble gases may be allowed to pass out to the exit drain.
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 an apparatus for the prevention of the escape of smoke or noxious gases
from chimneys, the method of treating or intercepting the smoke, divesting the
same of its soluble or noxious gases by means of precipit ion and thus preventing
their escape into the atmosphere being effected by mea of the interposition of
a chamber between the flue and the chimney into wh a water or other media
may be injected or passed in the form of spray or firely divided particles and
the soluble by-products or gas passed into an exit dain during the passage of
smoke from the flue into the spray chamber for the purj oses herein described.
2. The non-absorbent or non-porous chamber e for the purposes herein described.
3. The introduction or application of a finely divid d spray of water or other
media intercepting the smoke as indicated herein.
4. The combination of the syphon charged wither with the sump d of the
spray chamber substantially as and for the purposes hinly set forth.
5. The combination of the chamber c sprinklers : syphon substantially as
and for the purposes herein fully set forth.
