fixed at any desired distance therefrom and a connection made between it and the
tank above the water level by means of suitable pipes. The "blower" after
drawing the gases and other products of combustion from the flue or chimney into
the tank and water therein also withdraws them (after they have been separated
from the carbon and dust) from the tank and allows them to pass into the chimney
(above the damper) or into the air through a separate chimney in an innocuous
state, or it may be employed for returning the gases through suitable tubes to the
furnace and delivering them therein either above or below the fire.
The above described apparatus may be applied to flues or chimneys of boilers,
furnaces, kilns, destructors and the like.

Improvements in or relating to Means or Apparatus for Treating
Gases, Smoke, and other Products of Combustion so as to render
them Innocuous.
T, RICHARD WAINWRIGHT, of 145 Kirkstall Road Leeds in the County of
York Machine Broker and Oil and Tallow Refiner 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 improvements in means or apparatus for treating gases,
smoke, and other products of combustion, so as to render them innoxious. Its
object is to produce simple and ready means for preventing the gases, soot, dust,

page_text: and other particles that arise from the combustion of coal, coke, turf, wood, and
other combustibles escaping into the air in a noxious state.
In the drawings hereunto annexed I have shown at Fig. 1 (which is in section)
the invention applied to the chimney of a Cornish boiler, but I distinctly wish it to
be understood that its application is not limited thereto, but may be used for other
purposes, such as for instance, purifying or removing the sulphur from ordinary
carburetted hydrogen, as well as applied to the chimneys or flues of furnaces, kilns,
destructors, and the like.
A is the furnace, and B the flue of a Cornish boiler C, of ordinary construction
which is mounted upon brick work, so that the smoke and other products of com-
bustion after leaving the flue B, are conducted in the ordinary way by a fluc c along
the sides of the boiler into a flue D, and then returned to the chimney E.
suitable height in the chimney, a damper F is provided for preventing the smoke
and other gases escaping up the chimney into the atmosphere.
At a
The end of a pipe or tube G is passed into the chimney at any convenient
point, below the damper F and after passing, when required, through an inter-
mediary cistern H, (hereafter termed the cooler) the opposite end of the pipe G
is passed within the tank I, (hereafter termed the purifier) until the end is
submerged (within a few inches of the bottom of the purifier) in the water that
partially fills the purifier.
The greater the distance of the purifier I is from the chimney E the better will
be the action of the water on the sinoke, and other products of combustion, as they
will then enter the purifier in a cooler state.
In order to cool the smoke and other gases, as much as possible, in some cases
and when preferred the pipe G may be made to pass through the cooler H, which
is kept filled with water by means of a perforated water pipe El¹ (connected with
a suitable supply) fixed near the bottom of the cooler and below the pipe G so as
to play upon the latter for cooling the gases. The water after coming in contact,
with the pipe, will become heated, and may be drawn or pass out of the cooler
at H
In order to draw the smoke and other products of combustion out of the chimney
into the purifier, a fan or blower J (such as is known as a Root's blower) is
mounted upon the top of the purifier as shown, or at any suitable distance there-
from, and a connection made between it and the purifier by pipes. The "blower" J,
may be driven from any suitable source of power, and it is employed for the double
purpose of first forming a vacuum within the purifier, whereby the smoke and other
products of combustion are drawn from the chimney through the pipe G, and water
for purifying purposes; and secondly for withdrawing the purified gases from
the purifier and ejecting them in an innoxious state either into the atmosphere
through pipe K, or returning them to the chimney E through pipe K' shown
in dotted lines
or to the furnace A through pipe K" shown in dotted lines

By passing the smoke and other products of combustion through the water they
are separated from the carbon and dust which may be allowed to settle at the
bottom of the purifier and then be removed therefrom by manhole I. I is a
manhole for cleaning purposes.
By forming a vacuum within the purifier as described the gases, smoke, and
other products of combustion, are drawn into the water, and agitated therein
without any further mechanical means.
Suitable tap or taps may be employed for the removal of the water which may
afterwards be treated for the recovery of any chemical matter with which it may
be charged.
I desire it to be understood that I am aware that it has been proposed to treat
smoke by washing and absorbing the gases and other solid matter in a cylinder in
which they are kept in a violently agitated state by mechanical means, but to such
apparatus I lay no claim.

page_text: 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 the treatment of gases, smoke, and other products of combustion so as to
render them innoxious, the method of drawing them from the chimney or flue
through a pipe or tube into a purifier (partially filled with water) and out into
the atmosphere, or returned to the chimney in a purified state by means of a
vacuum formed in said purifier by a blower or fan substantially as herein set forth
and illustrated.
2. In apparatus for the treatment of gases, smoke, and other products of com-
bustion, the combination of the chimney E, and damper F with a pipe G, tank 1,
partially filled with water, blower J, and pipe K, or K, or K², substantially as and
for the purposes set forth.
3. In apparatus for the treatment of gases, smoke, and other products of com-
bustion, the combination of a blower J with a purifier I partially filled with water
and a conducting pipe G substantially as and for the purposes set forth.
