OR APPLICABLE TO HEATING STOVES OR FIRE PLACES FOR HEATING AND
VENTILATING PURPOSES." A communication from abroad by Henri Piron, of
Hodimont-Verviers, in the Kingdom of Belgium.
Sealed the 20th June 1879, in pursuance of an Order of the Lord Chancellor, and
dated the 12th December 1878.

Office of the Commissioners of Patents on the 12th December 1878.

"IMPROVEMENTS IN OR APPLICABLE TO HEATING STOVES OR FIRE
PLACES FOR HEATING AND VENTILATING PURPOSES." A communication from abroad
by Henri Piron, of Hodimont-Verviers, in the Kingdom of Belgium.
This Invention is based on the law of the gravity of air, and by its means is
ensured a regular and uniform temperature, varying between 17° and 21° centi-
grade, which is the best for health.
The object of the Invention is to provide for continuous ventilation and diffusion
in apartments, and halls, of pure air, charged with or of sufficient humidity, which
is most important; and further, and which is very desirable in crowded districts,
especially of discharging into the atmosphere only air that has been deprived of all
kinds of impurities, and which has been entirely carbonized before being discharged
from the chimney; and further by this system all soot and chimney fires are pre-
vented.
These heating stoves are constructed with a fire grate enclosed by two concentric
metal envelopes, casings, or shells, the outer serving as a hood or cover for the
interior casing, there being between the two an empty space, the outer casing being
plain, and the interior one fluted or corrugated. The open space between the two
casings is divided into a certain number of compartments communicating with each
Price 6d1

page_text: other by means of tubes, having airways or orifices communicating with the apart-
ment or hall so as to draw in the vitiated air, and purify it by passing it through
the fire, where by carbonization all organic and impure matters will be removed.
Furthermore the air will become mixed with the burning gases in the stove, and so
the last particles of carbon remaining, and which would otherwise be carried away
as smoke, will be consumed.
The same principles apply and give the same results in stoves and fireplaces for
private dwellings, which are constructed as follows:-These stoves are constructed
of a fluted pot like chamber of cast iron or other suitable material, within which is
the fire, and this chainber is enclosed or encased by a shell or cover of sheet metal,
which will be closed at its upper end by a metal cover or lid, which construction
allows of the carbonization of the vitiated air, and greatly increases the heating
surface, whereby economy of fuel will be effected.
By these special arrangements is established a natural ventilation, which purifies
the air, and by passing the air so drawn in through liquid there is imparted to it
that moisture which is necessary to render it fit for breathing purposes.

page_text: The following is a description of a large stove for heating purposes constructed
according to this Invention, and represented in Figs. 1 to 4. :-
A is the combustion chamber, composed of a channelled pot of metal, which may
be of cylindrical, conical, oval, or square shape, the corrugations whereof may be
horizontal, vertical, or spirally arranged. a is the entrance way of the air, which
passing over the strongly heated corrugations is burned and deprived of any noxious
matter which may have been held in suspension.
C is a metal hood, retort, or chimney, whereof the special form represented in the
Drawings, Fig. 2, ensures a regular combustion and greatly increased heating sur-
face, and consequent saving of combustibles. B is conduit in connection with the
exterior air, which passes between the cover f and the cover of the combustible
chamber, thus heating the air for diffusion within the rooms by the opening e,
after having been saturated with moisture in the reservoir R, which it is intended
shall be kept full of water; F is the door of the combustion chamber; G is the
ashpan, which should be kept about half full of water, in order that the falling
cinders may not produce a second fire, and that the evaporation of the water may
aid the combustion, and prevent the fire bars from burning; g is the poker
opening.
Having now described the nature and particulars of the said Invention in such
wise that the same may be carried into practical effect, I claim,-
First. The utilizing of heating stoves, hot air stoves, and domestic fire places, for
the double purpose of heating and of ventilation by giving them a simple form, and
securing great economy of combustion, as herein set forth, and shown by the
Drawings.
.
Second. The corrugating or channelling of the combustion chambers of hot air
stoves, heating stoves, and ordinary fire places, as herein before described, and
Third. The special hood, retort, or chimney C, as shown in Fig. 2 of the Drawings,
and for the purpose set forth.
In witness whereof, I, the said Walter Alfred Barlow, have hereunto set my
hand and seal, this Nineteenth day of June, in the year of our Lord One
thousand eight hundred and seventy-nine.
