PROVISIONAL SPECIFICATION.
Improvements in the Process of Producing Carburetted Air and in
Apparatus therefor.
I, HENRI REY, Administrateur Délégué de la Société Anonyme du Nouveau Gaz,
of Rue des Halles 19, Brussels, Belgium, do hereby declare the nature of this
invention to be as follows:-
The object of the present invention is to produce an illuminating and heating
gas at an elevated pressure by forcing air through a perforated plate which plunges
into a bath of mineral oil maintained at a convenient level by means of an oil
holder provided with a "Mariotte's pipe." By spraying through the oil bath,
the latter is converted into a fine dust and passes through a perforated cylinder,
bell or box, where it is divided again into a great number of currents, which are
deflected from a surrounding envelope so as to obtain a perfect atomization of the
mixture.
In order to maintain a convenient temperature in the apparatus, the oil bath is
heated by a coil placed below the perforated plate and through which is made to
circulate hot water or steam produced in a small boiler heated by a gas flame or by
a lamp.
In order to prevent condensation in the distribution pipe, a small regenerating
vessel containing quicklime is inserted in said pipe and is so arranged that the
carburetted air is obliged to circulate over or through the same whereby the air
is dehydrated by the quicklime under production of heat which regenerates the
condensed oil.
This property of the quicklime may be utilised during the process of car-
buretting the air by replacing the heating coil by a greater number of horizontal
plates supporting quicklime and having openings for the circulation of the air.
Oil is poured upon the quicklime by means of a regulating cock.
The carburetter may also be composed of two closed receptacles; one containing
the first indicated arrangement with a perforated plate and a heating coil for trans-
forming the oil into dust, and the other containing a series of horizontal plates
supporting quicklime where the dehydration of the air is effected and where the
gas is purified and reheated.
Instead of quicklime and similar substance as dry potassa or baryta may
be used.
The invention is completed by an air compressor consisting substantially of an
air pump the piston and the slide valve of which are actuated by excentrics and
by a transmission pulley. The continuity of the air current is obtained by means
of an air vessel provided with an elastic diaphragm. Also a safety valve provided
and so arranged that air will escape from it as soon as the pressure in the apparatus
increases above the normal pressure required. Consequently the air forced
through the carburetter will at any time correspond with the gas consumption
which may be variable.

I, Henri Rey, Administrateur Délégué de la Société Anonyme du Nouveau Gaz,
of Rue des Halles 19; Brussels, 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 object of the present invention is to produce carburetted air at an elevated
pressure as required for intensive incandescent gas lighting and heating purposes,
in such a manner that the air will lose but little of its initial pressure by friction
and that the heat of a simple gas burner will suffice to prevent the oil from
freezing even when producing great quantities of gas.
I attain these objects by forcing air through a single perforated plate which
plunges into a bath of mineral oil and which is heated by a coil in order to prevent
it from being obstructed by ice particles.
By spraying through the oil bath the oil is converted into a fine dust which
- passes through a perforated cylinder, bell or box, where it is divided again into a
great number of currents and deflected from a surrounding envelope acting as a
surface heater.
The apparatus is completed by an air compressor consisting of an air pump in
which the continuity of the air current is obtained by means of an air vessel
provided with an elastic diaphragm and with a safety valve so arranged that air
will escape from it into the atmosphere as soon as the pressure in the carburetter
. increases above the pressure required. Consequently the air forced through
the carburetter will at any time correspond with the gas consumption, which may
be variable.
In order to enable my invention to be fully understood I will now proceed to
describe the same with reference to the accompanying drawing in which :-
Figure 1 represents a vertical section of the improved apparatus and Figure 2
a plan view of the same.
A is the carburetter, B the air pipe, C the perforated plate, D the heating coil
through which circulates water heated in a small boiler E by means of a gas
burner or lamp F. G is a funnel for filling the oil holder H which maintains
automatically a convenient level in the carburetter by means of a Mariott's pipe I.
K is a pipe connection leading the pulverised mixture of oil and air into the
bell L which is provided with perforations M and surrounded by the envelope N
acting as a surface heater. () is the gaspipe and P a condensing vessel which
contains, upon grates, layers of quicklime for the purpose of absorbing the
condensed water contained in the air and of producing heat. Several of these
.vessels may be inserted in the gaspipe at convenient points.
Qis the piston of the air pump which is actuated by the eccentric R mounted
upon the axis S upon which is also mounted a second eccentric T operating the
distributing slide U. V is a transmission pulley, W is the air vessel provided
with an elastic diaphragm X of india rubber and with a safety valve Z.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:
1. In an air carburetter, the combination of a perforated plate C plunging
into an oil bath and having a heating coil D placed directly upon it, with a
perforated cylinder L surrounded by a deflecting envelope N, substantially as
shown and for the purpose specified.

page_text: 2. In an air carburetter having a perforated plate C heated by a coil D and a
perforated cylinder L surrounded by a deflecting envelope N, the air vessel W
provided with an india rubber diaphragm X, a safety valve Z and an air tube B
communicating with the carburetter A below the perforated plate C, substantially
as set forth.
3. In an air carburetter as claimed, the condensing vessel P, containing upon
grates a certain quantity of quicklime and being inserted in the gaspipe O at
convenient points, as and for the purpose described.
