I, CLEMENT MATHIEU, Administrateur délégue de la Société Anonyme du Gaz
Aéropétrolique, of 7, Rue Breughel, Brussels, in the Kingdom of Belgium, do
hereby declare the nature of this invention to be as follows:-
The present application refers to a system of carburetting apparatus for feeding
gas engines and for producing an illuminating and heating gas by recarburetting
the burned products.
In the first place, the invention consists in the combination of an air car-
buretter with a gazificator of great surface, heated by the burned gases of the
engine. The air is drawn in by the gas engine itself though filtering layers of
cotton moistened by a mineral oil with such a velocity as to reduce the oil to
a fine dust, the condensation of which is prevented by the gazificator, thereby
producing a rich and dry gas in which the proportion of oxygen is too small for
rendering the gas explosible without further addition of air.
In the second place, the invention consists in the recarburetting of the burned
products of gas engines. To this end, the products of combustion are led into
an expansion vessel where they can fully expand, so as to conserve only the
pressure and heat required for getting through the recarburetter and for main-
taining there a temperature corresponding with the external air.
As the quantity of the burned products and the ratio of consumption of the
recarburetted gases are variable, the process is completed by a regulator which
consists in the combination of recarburetter with a bell or gasometer, which by
means of a bar, chain or string actuates a three way valve, slide or cock in such
a manner that as soon as the gas raises the bell, the latter will gradually shut
off the passage leading the burned products to the expansion vessel and open at
the same time the passage for the escape of said products into the atmosphere.
The air-carburetter consists of a cylindrical envelope fixed upon the bottom of
a water tank and closed on top. The inner space of the envelope is divided by
a series of wire work grates for supporting filtering cotton layers which are
irrigated with petroleum or other mineral oil by means of a perforated coil which
At each aspira-
itself is connected with an oil reservoir placed at a higher level.
tion of the gas engine a certain quantity of air enters into the carburetting
apparatus at its lower part and by passing upwards pulverizes the oil and carries
it into the gasificator which is fixed to the gas sucking valve of the engine. The

page_text: gasificator consists of a long tube which is surrounded by the discharge tube
having an increased diameter. The apparatus is moreover provided with a funnel
and with a discharge cock.
The water tank of the carburetter is connected by pipes with the water jacket
of the gas engine so as to produce a circulation of the water through said tank
which acts as a refrigerator.
The recarburetter is of similar construction but connected with the expansion
vessel in which enter the burned products of the gas engine after having passed
through a three way valve commanded by a rod attached to the bell of the
recarburetter.
A retaining valve is provided between the recarburetter and the expansion
vessel, which latter may be placed under the tormer (the recarburetter).
The burned products after having passed through the recarburetter, are directed
into a pressure regulator and thence pass into the distribution pipe. A tube is
also provided for leading the recarburetted gas to the burner of the gas engine.
The carburetted gas produced with the burned products discharged from gas
engines is a light gas, but as it does not contain any oxygen, it is absolutely
inexplosible in itself and constitutes a very good heating and illuminating gas.

Process and Apparatus for Feeding Gas Engines with Carburetted Air
and for Producing an Illuminating and Heating Gas by Recar-
buretting the Burned Products.
İ, CLEMENT MATHIEU, Administrateur délégue de la Société Anonyme du Gaz
Aéropétrolique, of 7, Rue Breughel, Brussels, in the Kingdom of Belgium, 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:
The present application refers to a system of carburetting apparatus for feeding
gas engines and for producing an illuminating and heating gas by recarburetting
the burned products.
In the first place, the invention consists in the combination of an air car-
buretter with a gazificator of great surface, heated by the burned gases of the
engine. The air is drawn in by the gas engine itself though filtering layers of
cotton moistened by a mineral oil with such a velocity as to reduce the oil to
a fine dust, the condensation of which is prevented by the gazificator, thereby
producing a rich and dry gas in which the proportion of oxygen is too small for
rendering the gas explosible without further addition of air.
In the second place, the invention consists in the recarburetting of the burned
products of gas engines, whereby a gas is produced which serves in the first
place for feeding the incandescent tube of the gas engine, but which may also
be produced in sufficient quantities for illuminating purposes.
To this end the
products of combustion are led into an expansion vessel where they can fully
expand, so as to conserve only the pressure and heat required for getting through

page_text: the recarburetter and for maintaining there a temperature corresponding with
the external air.
I attain these objects by the apparatus illustrated in the accompanying draw-
ing, in which,
Fig. 1 is a vertical section, and,
Fig. 2 a plan view.
The air-carburetter consists of a cylindrical envelope A, fixed with its enlarged
portion upon the bottom of a water tank B and enclosed on top. The inner
space of the envelope is divided by a series of wire work grates for supporting
filtering cotton layers C which are irrigated with petroleum or other mineral oil
by means of a perforated coil D which itself is connected with an oil reservoir
placed at a higher level. At each aspiration of the gas engine a certain quantity
of air enters into the carburetting apparatus at its lower part through pipe E
and by passing upwards pulverizes the oil and carries it into the gasificator
tube which is fixed to the gas sucking valve of the engine and which is sur-
rounded by the discharge tube G having a suitably increased diameter.
The water tank of the carburetter is connected by pipes H H (Fig. 2) with the
water jacket of the gas engine so as to produce a circulation of the water through
said tank which acts as a refrigerator.
The recarburetter A¹ is of similar construction but connected with the expan-
sion vessel I in which enter the burned products of the gas engine.
As the quantity of the burned products and the ratio of consumption of the
recarburetted gases are variable, the process is completed by a regulator which
consists in the combination of recarburetter with a bell or gasometer K which
by means of a bar L chain or string actuates a key M of a three way valve N
in such a manner that as soon as the gas raises the bell to a certain height, the
key M, which is hollowed and partly filled with mercury will shut off the passage O
leading the burned products to the expansion vessel I and open at the same time
the passage P (Figs. 1 and 2) for the escape of said products into the atmosphere.
A retaining valve Q is provided between the recarburetter and the expansion
vessel I, which latter may be placed between the two carburetters.
The burned products after having passed through the recarburetter, are directed
into a pressure regulator R and thence pass into the distribution pipe S. A
tube T is also provided for leading the recarburetted gas to the burner of the
gas engine.
The carburetted gas produced with the burned products discharged from gas
engines is a light gas, but as it does not contain any oxygen, it is absolutely
inexplosible in itself and constitutes a very good heating and illuminating gas.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
1. The process of producing carburetted air for feeding gas engines by passing
the air, sucked in by the gas engine, through filtering material moistened by
a mineral oil and then through a long gazificator tube, which latter is heated
by the burned products of the gas engine and not submitted to any pressure.
2. The process of recarburetting the burned products of the gas engine, by
first leading them into an expansion vessel and then through a carburetter for
the purpose of producing an illuminating and heating gas specially for feeding
the burner of the gas engine.
3. The special means for working the process claimed at 1 and 2, consisting
of an air carburetter A, of a gasificator tube F connecting the carburetter with
the gas engine, of the discharge tube G surrounding the gazificator tube F and
entering into an expansion vessel T and thence into a second carburetter A',
all substantially as described and represented.
4. The mode of regulating the inlet of the burned products into the expansion
vessel T by means of a three way valve inserted in the discharge pipe G and actu-

page_text: ated by means of a rod L fixed to a bell K surrounding the carburetter, all sub-
stantially as shewn.
5. The arrangement of the air carburetter in a water tank which is connected
with the water jacket of the gas engine by means of the tubes H H¹.
