"IMPROVEMENTS IN CARBURETTING APPARATUS FOR THE MANUFACTURE OR
TREATMENT OF GAS FOR LIGHTING AND HEATING PURPOSES." (A. communication
from abroad by Victor Charles Devobz, of Paris, France.)
The Invention relates to a novel kind of carburetting apparatus for the manu-
facture of gas, applicable either for lighting or heating purposes, from atmospheric
air or coal gas, and the vapours or more volatile portions of mineral oils.
According to one part of the Invention, atmospheric air is forced under pressure
into a receiver provided with a manometer, and passes thence into the carburettor
by a pipe terminating in a rose perforated with very small holes, for the purpose of
dividing the air into fine jets, so that it may easily become mixed with the vapours
that are disengaged from the mineral oil contained in the lower part of the
carburettor.
The carburettor is composed of a series of circular superposed cast iron parts
connected together by flanges and bolts. Between each pair of these parts there
are fixed diaphragms of metallic gauze for the purpose of producing a complete
and intimate mixture of the ascending current of air with the combustible
vapour.
The upper part of the carburettor forms a chamber, to which are connected pipes
to convey the gas to the different points where it is to be consumed.
To the lower part of the carburettor is attached a mineral oil feed pipe connected
to a funnel, a gauge glass and a cleaning out pipe, for the withdrawal of the heavy
oils that remain in the apparatus after the more volatile parts have been absorbed
by the air flowing through the apparatus.
The carburettor is surmounted by a small testing apparatus, constructed in a
similar manner to that described above, of cast iron parts connected together by
means of flanges and bolts, and provided with metallic gauze diaphragms. This

of a cock.
This testing apparatus carries at its upper part a small burner, by means of which
a trial may at any time be made of the nature and quality of the gas produced.
The metallic gauze diaphragms prevent the flame from being carried into the
apparatus, and obviate all risk of explosion.
Furthermore, the carburettor apparatus is applicable for enriching ordinary
lighting gas made from coal, and for this purpose has a pipe terminating in a small
rose to convey into it the gas which it is desired to treat.
When the gas produced as above described is used for heating furnaces, the
ordinary fire grate is replaced by a hollow iron worm, perforated at the top
with holes, and fixed on a cast iron plate, which closes the ash pit of the furnace.
For use in domestic fire places, a similar arrangement may be employed, or any
suitable appliance may be substituted for it.
