PROVISIONAL SPECIFICATION.
Smoke and Noxious Gas Consuming Apparatus.
ALFRED WILLIAM DOLMAN Château St. Jacques d'Arricau par Lembeye,
France do hereby declare the nature of this invention to be as follows :-
:―
The smoke and noxious gas are led, by tubes of zinc, or other materials, into
water. The main tube has an air opening, to secure a draft, for the fire, & the
smoke and gas escaping by it, is captured by a second tube which discharges itself
into a water tank. Where the second tube rests on the first, an opening is made,
in the second tube to allow air to enter. And this opening is made, by a portion
of the second tube, revolving by the action of a rod, cowl headed, to face the wind.
A third tube may be placed, bell shaped, to hang over the air hole & the opening
in the second tube, & lead its contents either into the second tube, or into water.
Blowers, funnel shaped, are placed when required, to increase the draft & their
tapering ends must be laid a few inches inside the tubes.

COMPLETE SPECIFICATION.
Smoke and Noxious Gas Consuming Apparatus.
I ALFRED WILLIAM DOLMAN, Roman Catholic Priest, Château St. Jacques
d'Arricau, par Lembeye, Basses Pyrenées, France, 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 apparatus having as object to consume the smoke and
noxious gases arising from fireplaces, furnaces and the like, and in accordance
therewith such smoke or gas is conducted from the grate into a bath of water
provided where the same is destroyed.
And in order that this my invention may be fully understood and readily carried
into effect, I will proceed to describe the same with reference to the accompanying
drawing, which represents in sectional elevation my smoke and noxious gas
consuming apparatus applied to a chimney or flue.
Hermetically sealed within the chimney a and at a suitable height to secure
sufficient draught, I have a bell shaped or conical hood or chamber from which
hood or chamber 6 I have a tube c leading therefrom into the bath or tank d
provided and terminating below the level of water contained in the tank. The
smoke then must pass from the fire or furnace in the direction indicated by arrows
in the drawing into the hood or chamber 6 from whence it traverses the tube c and
passes into the water contained in tank & where it is destroyed. To assist the up
draught I may form an opening or aperture e in the tube c and any smoke or gas
escaping therefrom is again carried into the chimney a and passes upwards into the
chamber 6 and from thence through tube c into tank d, all as indicated by arrows.
In some instances it may be necessary in order to assist draught to employ or
make use of a tube f (shewn in dotted lines) placed vertically within the chimney a.
The length of this tube will vary in accordance with the force of the draught in
the chimney and it is necessary that the grate or furnace should be hermetically
sealed so that any smoke or gas may be prevented escaping therefrom into the
chamber, room or other place in which said grate or furnace is situated.
D

page_text: In the case of a stack of chimneys or where two or more flues discharge their
smoke side by side, these flues may be caused to emit their smoke into a common
receptacle from which by one common tube the smoke or gas may be led into
the bath.
The process and apparatus as above described may be applied to any chimney or
funnel whether on shore or at sea.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim, is:
The smoke and noxious gas consuming apparatus constructed and arranged in
such manner that the said smoke and noxious gases are conducted from the fire or
furnace through a tube or tubes into a tank or bath of water where the same are
destroyed, substantially as herein before described and shewn in the accompanying
drawing.
