MYLIUS and THOMAS PROBIN VON MYLIUS, both of Adam
Street, Burnley, Bourke, Victoria, Australia, Manufacturers.
Improvements in smoke-consuming furnaces.

Extract from Specification.—With our invention the un-
burned gases, fresh from the coal, instead of striking against
comparatively cold surfaces such as the walls of the furnace,
the combustion-chamber, or the tubes, and then being li-
berated into the chimney, impinge against the hot surface
of a refractory material or firebrick. This is presented by
a refractory diaphragm and also by a refractory mixture-
chamber. In addition to which steam (wet or superheated)
and an auxiliary heated current of air is supplied to the gases
in the mixture-chamber, which chamber provides the con-
servation of temperature which is essential to smokeless
combustion, and effectively mixes the unburned gases from
the fire, the air, and the steam.
[NOTE.—The above extract from the specification is inserted in place
of the claims.]

No. 20679.—6th February, 1906.—ANDREW JACK, of
Palmerston North, New Zealand, Plumber. Improved means
for use in the generation of gas from hydrocarbon oils.

Claims.—(1.) In means for use in the generation of gas from
hydrocarbon oils, a carburetting-chamber into which air
is introduced under pressure, and heated if desired, and
into which a quantity of oil is fed, and a drum mounted
longitudinally within the chamber and provided with means
for rotating it, such drum being provided with a number of
small vanes or buckets extending in parallel lines along
its peripheral face and adapted to dip into and raise the
oil and spread it over the drum’s surface as the drum is ro-
tated, substantially as specified. (2.) In means for use
in the generation of gas from hydrocarbon oils, the com-
bination with means for storing air under pressure and for
heating it of a carburetter comprising a chamber with an
enclosed space beneath it into which space the heated air
is admitted, a rotating drum mounted longitudinally within
the chamber and provided with a number of small vanes
or buckets extending along its peripheral face, a pipe leading
from the space beneath the chamber and extending along
in front of the drum, such pipe being formed with perforations
in it throughout its length, and means whereby a constant
quantity of oil is automatically supplied to the chamber,
substantially as specified. (3.) In means for use in the gene-
ration of gas from hydrocarbon oils, a carburetting-chamber
approximately of the form shown in the drawings, an en-
closed space beneath such chamber into which heated air
under pressure is fed, a pipe leading from such space into the

chamber and extending along one side thereof, such pipe
being formed with perforations in it throughout its length,
a rotating drum mounted longitudinally within the chamber
and provided with vanes or buckets extending along its face,
and means whereby a constant level of oil is maintained
within the chamber, substantially as specified. (4.) The
general arrangement, construction, and combination of parts
in my improved means for use in the generation of gas from
hydrocarbon oils, as described and explained, as illustrated
in the drawings, and for the several purposes set forth.
