Improvements in the Method. of and Apparatus for Charging :Air
with Combustible Matter and Applying it for Illuminating.
I,' LOUIS DENAYROUZE, 'of '70 Boulevard Victor Hugo, Neuilly, (Seine)
France, Engineer, do hereby declare the dature of this invention to be as
follows:-
My invention relates to-means of .charging..air with combustible matter, such as
the vapour of liquid or solid hydrocarbons, or with pulverulent..matter such
as charcoal powder, lycopodium and the like, and applying the air so charged for
illuminating.
My chief object is to effect the charging of the air at the lamp itself, to
which air under pressure is supplied, the mains and service pipes now used for: gas
being available for that. purpose. The air supplied should have a pressure
higher than that. at which gas is usually supplied, it may be equivalent to 30 to
40 inches of water column. The construction and arrangement of the lamp, where
the charging of the air takes place, vary according to the nature of the combustible
matter employed. When this is a more or less volatile hydrocarbon liquid,
I adopt the following arrangement. The air:under pressure is supplied by the
ordinary-service-pipe to a.chamber in the lower part of the lamp, and issues in a
jet across the mouth of a small pipe which dips into the liquid below; thus causing
a finely subdivided spray of the liquid to flow with the air current against the vanes
of a fan or flyer which revolves in a casing communicating with the burner and
serves to mix the air and hydrocarbon thoroughly and uniformly. The fan-may
be driven merely by the impact of the current on its blades, or it may be caused to
rotate by an electric or other:motor.
When the hydrocarbon is in the form of a solid such as naphthalive, it is
contained in. a vessel some distance above the flame, by the heat of which it
is kept in a state of fusion while the air blows over its surface taking up vapour
from it.
The air is generally too-much enriched in this manner, and therefore I so arrange
the mixing fan as to draw in additional air and. mix it with the enriched air-before
it passes to the burner. For starting the operation of this apparatus, the vessel
containing the hydrocarbon has first to be heated.
When the combustible matter is in the form of a fine powder, I mount at the
bottom of the vessel.containing it, a small feed roller, which may be of wood, and
which is caused.to-revolve-slowly by gearing.connecting it to the rapidly revolving
mixing fan...As. this roller revolves, it carries on its surface a coating of the
combustible powder,-and-the jet of air, being directed on this, blows it foff into the
fan chamber, where the air (and powder. are thoroughly mixed, and whence they
proceed to the burner. In this case a small electric motor is preferably employed
to work the fan and feed roller.

I, LOUIS DENAYROUZE, of 70 Boulevard Victor Hugo, Neuilly, (Seine)
France, Engineer, 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 :-
My invention relates to means of charging air with combustible matter, such as
the vapour of liquid or solid hydrocarbons, or with pulverulent matter such
as charcoal powder, lycopodium and the like, and applying the air so charged for
illuminating.
My chief object is to effect the charging of the air at the lamp itself, to which
air under pressure is supplied, the mains and service pipes now used for gas being
available for that purpose. The air supplied should have a pressure higher than
that at which gas is usually supplied, it may be equivalent to 30 to 40 inches of
water column. The construction and arrangement of the lamp, where the charging
of the air takes place, vary according to the nature of the combustible matter
employed. When this is a more or less volatile hydrocarbon liquid, I adopt the
arrangement shewn in Fig. 1 of the accompanying drawings, in elevation partly
sectional. The air under pressure is supplied by the ordinary service pipe F to a
casing A in the lower part of the lamp, and issues in a jet across the mouth of a
small pipe E which dips into the liquid in a receptacle D below, thus causing
a finely subdivided spray of the liquid to flow with the air current against the
vanes of a fan or flyer which revolves in the casing A which communicates
with the burner tube H; and this fan serves to mix the air and hydrocarbo
thoroughly and uniformly. The fan may be driven merely by the impact of
the air current on its blades, or it may be caused to rotate by an electric or other
motor.
When the hydrocarbon is in the form of a solid such as napthaline the apparatus
may be arranged as shewn in Fig. 2. The napthaline is contained in a vessel J
some distance above the flame, by the heat of which it is kept in a state of fusion
while the air entering the vessel by a conical inlet K blows over its surface taking
up vapour from it. The air is generally too much enriched in this manner, and
therefore so arrange the mixing fan as to draw in additional air at a central
orifice L and mix it with the enriched air before it passes to the burner. For
starting the operation of this apparatus, the vessel J containing the hydrocarbon
has first to be heated.
When the combustible matter is in the form of a fine powder I arrange the
apparatus as shewn in Fig. 3. I mount at the bottom of the vessel T containing
the powder a small feed roller S which may be of wood and which is caused to
revolve slowly by worm or other suitable gear connecting it to the rapidly revolving
mixing fan O. As this roller S revolves, it carries on its surface a coating of the
combustible powder, and the jet of air, being directed on this from the pipe 6 blows
it off into the fan chamber, where the air and powder are thoroughly mixed, and
whence they proceed to the burner tube H. In this case a small electric motor P
is preferably employed to work the fan and the feed roller.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The herein described method of charging air with combustible matter and
applving it for illumination by sending air undas suitable seadorata.
DROCCIO hv

page_text: the ordinary gas service pipes, in the immediate neighbourhood of each burner
mixing it with combustible vapour or dust, and transmitting the mixture direct to
the burner.
2. For operating as above set forth with volatile liquid hydrocarbon, apparatus
constructed and operating substantially as described with reference to Fig. 1.
3. For operating as set forth with solid hydrocarbon, apparatus substantially as.
described with reference to Fig. 2.
4. For operating as set forth with combustible dust, apparatus substantially as
described with reference to Fig. 3.
