COMPLETE SPECIFICATION (AMENDED).
Improvements in the Construction of Gas Burners.
I, CHARLES EARDLEY BILLING, of 100, Abbey Road, West Hampstead, Gas
Engineer, 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:
This invention relates to a construction of gas burner which allows a powerful
light to be obtained without the use of incandescent mantles and with less expendi-
ture of gas than is generally the case.
In connection with my improved burner I employ a double chimney of glass,
mica or the like. The outer chimney is preferably lower than the inner and
allows a current of heated air to pass down the annular chamber between the two
chimneys to the burner. The support for the outer chimney is closed by a tale
or other suitable disc preventing the air passing through so that all the heated

air flowing between the two chimneys passes through the burner.
part of the chamber so formed I propose to place a metal case or chamber formed
in the burner, the gas being caused to pass through this chamber before it reaches
the aperture. The heated air striking upon this metal chamber causes the gas
passing through it to become heated before it is ignited and by this means a much
brighter flame is produced. The chamber is provided with suitable material
through which the gas can pass, two layers being preferably employed the lower
one consisting of charcoal and the upper of asbestos. These are separated and
enclosed by small discs of wire gauze or by perforated plates.
In order that the invention may be more clearly understood, reference is had to
the accompanying drawing, which shows my improved burner in section. A
and A¹ are respectively the inner and outer chimneys carried in the sockets B
and B¹.
The chimney A' is shorter than A and is of sufficient diameter to leave the
annular chamber a between them. The support or socket B' has its openings closed
by the disc b of talc, glass or the like so that no air can penetrate through this
part. The burner is provided with a metal chamber C placed below the inner
chimney and within the lower end of the outer one so that the heated air passing
through the annular passage a will strike 'directly upon the heating chamber.
This chamber as shown is made in two parts screwed together by means of small
flanges. The lower part of the chamber is provided with the layer D of charcoal
to pass
and above this is the layer D' of asbestos. Both these layers allow the
through and the asbestos prevents any particles of carbon being carried by the
gas. These layers are supported and separated by the discs E of wire gauze cr
perforated plate.
gas
With a burner constructed in this matter not only is heated air supplied to the

before it is ignited so that the greatest possible efficiency. is ensured and the
incandescence of the gas raised to the highest possible degree.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) In an improved burner, the combination with two chimneys forming an
annular chamber through which heated air can be drawn, of a chamber formed in
the burner at its lower end and within the outer chimney, and layers of charcoal
and asbestos or like material in the said chamber through which the gas must
pass before ignition, the chamber being heated by the air passing to the burner
substantially as and for the purposes specified.
(2) The improved gas burner having two chimneys between which heated air
can be drawn to the burner formed with a metal chamber at its lower side situated
in the lower end of the outer chimney, discs of wire gauze or perforated plates
within the said chamber, a lower layer of charcoal and upper layer of asbestos
between the said discs, heating the gas before it is ignited, substantially as
described and shown and for the purposes specified.
Dated this 20th day of December 1897.
