Improvements in Means or Apparatus for Burning Illuminating Gas.
I THEODORE BIRNBAUM, of Wick Lane Rubber Works, Bow, in the County of
Middlesex, India Rubber Manufacturer do hereby declare the nature of this invention
to be as follows:-
This invention relates to means or apparatus for use in burning gas for illumination,
particularly adapted for factories and other places where explosive vapour or gases
may at times be present.
In carrying out my invention I employ a pipe of supply for the illuminating gas
to be burned and this pipe may, if desired, be made the means of support for the
entire apparatus, or this can be otherwise contrived. This pipe passes through, and is
securely packed to, a glass or other transparent globular, or semi-globular, shade at
the lower part, by preference, to avoid downcast of shadows.
Within this globe an inlet for air is provided for supply and admixture of air with
the gas to be burned. Within this globe and around the pipe is applied a tube of
transparent material as fine mica (glass being liable to fracture) and the pipe termi-
nates in a suitable burner, covered with a mantle which may be of the ordinary
character employed for incandescent gas illumination.
The upper open part of the globe is covered (except the portion occupied by the
tube, or chimney of mica, or other suitable transparent material) with fine wire
gauze or like fine reticulate openwork and the chimney which extends for some
distance above the enclosed globe, is fitted with an extension and closed top, or
cover of similar gauze or openwork material.
By these means atmospheric air to support combustion is supplied to the burner
through the interstices of the gauze over the globe and the products of combustion find
their exit through the cap to the chimney, but access of vapours or gases to the flame
directly is prevented and danger of ignition of any such floating vapours is
avoided.
The inflowing currents of air also serve to reduce the temperature of the globe,
by impeding radiation of heat from the chimney thereto and also to modify the
heat of the chimney itself, whilst at the same time warming the air supplied to
the burner.

Improvements in Means or Apparatus for Burning Illuminating Gas.
I THEODORE BIRNBAUM, of Wick Lane Rubber Works, Bow, in the County of
Middlesex, India Rubber Manufacturer do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to means or apparatus for use in burning gas for illumination,
particularly adapted for factories and other places where explosive vapour or gases

the accompanying drawings.
Figure 1 shows by a vertical sectional elevation an arrangement of apparatus
adapted for carrying out my invention.
if
a is a pipe of supply for the illuminating gas to be burned and this pipe may
desired, be made the means of support for the entire apparatus or this can be other-
wise contrived. This pipe passes with the interposition of suitable packing material
or closing contrivances, through a (by preference) glass or other transparent globular,
or semi-globular shade b at the lower part, the globular shade 6 being securely held by
the dished flange a' upon the supply pipe a.
The burner employed although here shewn as an ordinary incandescent gas
lighting burner may be of any suitable form and construction.
Within this globe I have shewn for the Bunsen burner an inlet, or inlets, c for air
such as for that type of burner needs to be provided for supply and admixture of
air with the gas to be burned. Within this globe and around the pipe is applied a
tube d of transparent material as fine mica (glass being liable to fracture) and the pipe
terminates in a suitable burner e covered with a mantle which may be of the
ordinary character employed for incandescent gas illumination.
The upper open part of the globe is closed by means of a metal or similarly
refractory cylinder resting on or supported by a cap, or support. The chimney may
be of mica or other suitable translucent or transparent material and the chimney cap
rests upon an annular piece or ring of perforate material sufficiently fine to prevent
ignition taking place through its interstices. For this purpose I prefer miner's
wire gauze.
At the upper end the chimney h which extends for some distance
above the enclosed globe, is fitted at its upper end or outlet with a hood i of like
material (say miner's wire gauze).
I sometimes provide a spreader k above the open end of the ordinary chimney d
to the better diffuse the heated air current.
Air to support combustion of the gas at the burner passes in at the openings
in the annular piece 9 and thence down through the closed bowl b to the openings c
and to the base of the chimney d.
Air also passes up between this chimney d and the cylinder h for the cooling
purpose stated.
The products of combustion and heated air pass up and away through the inter-
stices of the hood i whilst passage of flame is prevented and down draught avoided.
Although the drawings show what is commonly known as an incandescent gas
burner, an Argand or other suitable burner may be used.
For street lighting or in other places open to draughts I provide a hood / to
form a cover for the perforated zone 9 see Figure 2, which shows the lamp in
elevation, the hood 7 being partly in section.
By these means atmospheric air to support combustion is supplied to the burner
through the interstices of the gauze over the globe and the products of combustion
find their exit through the cap to the chimney, but access of vapours or gases to
the flame directly is prevented and danger of ignition of any such floating vapours
is avoided.
The inflowing currents of air serve to reduce the temperature of the globe, and
the continuously ascending current of air passing between the chimney and the
surrounding cylinder by impeding radiation of heat from the burner through the
chimney thereto keeps down the heat of the chimney itself and generally improves
the operation of the lamp.
The combustion supporting air current supplied to the burner by its passage
through the lantern becomes heated and better prepared adapted to its purpose.
my
Having now particularly described and ascertained the nature of said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The construction or arrangement and use of the improved means or apparatus

page_text: for burning illuminating gas so as to prevent explosion of surrounding inflammable.
gases or vapours, or finely divided powders, substantially as shewn and described.
2. In a lamp for burning illuminating gas the construction and use of parts.
adapted to prevent the radiation of heat from the flame by means of an interposed
current of cold air, substantially as set forth.
3. In a lamp for burning illuminating gas the construction or arrangement of
parts so as to obviate down draught, substantially as set forth.
4. The construction or arrangement of parts of a lamp for burning illuminating
gas and its use, whereby the explosion of surrounding inflammable gases, or vapours,.
or finely divided powders is avoided, the radiation of heat from the flame is prevented
and down draught is obviated, substantially as set forth.
5. As a lantern, or means, to enclose a gas burner for illuminating purposes, a
metallic cover, with an annular piece or ring of suitably fine openwork, as miner's
wire gauze in connection with a closed translucent bowl and an air current conduct-
ing cylinder and a metal wire gauze, or equivalent fine openwork hood or down
draught and flame excluding cover, substantially as and for the purpose set forth.
Dated the 8th day of September 1896.
