Improvements in Incandescence Vapour Lamps.
I, CHARLES CLIFFORD BRUCKNER, of 72, Morningside Avenue, New York City,
New York, United States of America, Manufacturer, do hereby declare the nature
of this invention and in what manner the-same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to an incandescence oil lamp so constructed that it has
an initial vaporizer which can be sufficiently heated by the flame of a match
to generate vapour for lighting the burner jet, as I shall describe referring to
the accompanying drawings.
Fig. 1 is a vertical central section of a lamp according to this invention and
Fig. 2 is a sectional detail of the jet fitting.
A is the communication from the oil reservoir which is hermetically closed
but provided with means (not shown) for applying pressure to the contained oil:
B is the Bunsen burner, 2 the chimney holder, 3 the chimney 4 the incandescent
mantle, and 5 is a screw plug for regulating the supply of oil. 6 is a tube
leading up from 5 to a tube coupling 7; 8 is a partly spherical casing beneath
the burner within which is arranged the U shaped mixing chamber 9, one limb
of which leads to the burner, the other limb, having air inlets 10, and a
coupling 11 to the vapour tube 16. The lower and enlarged part of the coupling
has a gauze or perforated diaphragm 12, and jet fitting 13, which is non metallic
being preferably quartz or crystal, the opening through which, has a surface so
smooth and hard that deposits of free carbon do not adhere to it as is the case
with softer and more porous substances such as metal. The main vaporizer is
an annular tube concentric with the burner and in the plane of its vapour
openings with it is connected the vapour tube 16 and the oil tube 15 leading
to the coupling 7. The tube 16 is preferably formed into a coil as shown, to
which a match flame can be readily applied. This tube should have a bore not
exceeding inch so as to give passage to a mere filament of oil, and its wall
should be not less than inch in thickness so as to retain for some time the
heat applied to it. This flame heats the tube sufficiently to vaporize the first
flow of oil, the vapour passing to the burner to be ignited, the heat retained in
the coil being sufficient to continue the vaporizing action until the flame of the
burner heats the tube C sufficiently to generate a continuous supply of vapour
for the burner.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim
is:-
1. In combination with an incandescence oil burner, an initial vaporizer con-
sisting of a filamentary tube preferably coiled, substantially as described.
2. In combination with an incandescence oil burner, a vaporizer consisting of
an annular tube concentric with the burner and in plane with its top openings
substantially as described.
3. In combination with an incandescence oil burner a mixing chamber beneath

page_text: the burner a source of oil supply under pressure, a main vaporizer at the top
of the burner and concentric with it connected with the source of oil supply, and an
initial vaporizer between the main vaporizer and the mixing chamber substantially
as described.
