PROVISIONAL SPECIFICATION.
Improvements in Gas Burners and Apparatus for Naphthalising Gas.
1. THOMAS TRAVERS, of The Cork Gas Co., Cork, Gas Engineer, do hereby
declare the nature of this invention to be as follows :-
This invention has for its object improvements in gas burners and apparatus for
naphthalising gas.
It is well known that when coal gas is passed over naphthaline at a suitable
temperature it takes up vapour from the naphthaline and when burnt after being
so impregnated it gives a much better light than is obtained when the gas is used
in its original state.
con-
The apparatus heretofore commonly employed when using naphthalised gas is
however open to the objection that the gas is not properly enriched for a
siderable time after lighting and also a very considerable gas pressure is requisite
to the proper working of the apparatus.
To overcome these difficulties I resort to the following construction - provide
over the burner a concave reflector and this forms the bottom of the naphthaline
receiver. The receiver is annular in form and a chimney or passage for the products
of combustion passes up through the centre of the naphthaline receiver. The gas
pipe descends centrally through this chimney or passage and it serves to support
the receiver which is connected with it by two tubes passing radially from the pipe
to the sides or walls of the chimney or passage which is perforated where it is met
by the tubes. One of these tubes serves to admit the gas to the naphthaline
receiver at the top and the other serves to allow the gas when naphthalised to pass
back into the pipe and thus to descend to the burner. There is a partition in the
pipe between the radial tubes so that the gas is compelled to traverse the naphtha-
line receiver in order to reach the lower part of the pipe and by it to descend to the
burner. The pipe terminates in a small bulb about ten inches below the reflector
and into this bulb the gas nipples usually three in number are set, somewhat
obliquely so that when the gas is ignited at the nipples the gas flames heat the pipe
which they surround but without playing directly upon it.

COMPLETE SPECIFICATION.
Improvements in Gas Burners and Apparatus for Naphthalising Gas.
I, THOMAS TRAVERS, of The Cork Gas Co., Cork, 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 has for its object improvements in gas burners and apparatus for
naphthalising gas.
It is well known that when coal gas is passed over naphthaline at a suitable
temperature it takes up vapour from the naphthaline and when burnt after being so
impregnated it gives a much better light than is obtained when the gas is used in
its original state.
The apparatus heretofore commonly employed when using naphthalised gas is
however open to the objection that the gas is not properly enriched for a co-
siderable time after lighting and also a very considerable gas pressure is requisite
to the proper working of the apparatus.

page_text: To overcome these difficulties I resort to the following construction :-I provide
over the burner a concave reflector and this forms the bottom of the naphthaline
receiver. The receiver is annular in form and a chimney or passage for the
products of combustion passes up through the centre of the naphthaline receiver.
The gas pipe descends centrally through this chimney or passage and it serves to
support the receiver which is connected with it by two tubes passing radially from
the pipe to the sides or walls of the chimney or passage which is perforated where
it is met by the tubes. One of these tubes serves to admit the gas to the naphtha-
line receiver at the top and the other serves to allow the gas when naphthalised to
pass back into the pipe and thus to descend to the burner. There is a partition in
the pipe between the radial tubes so that the gas is compelled to traverse the
naphthaline receiver in order to reach the lower part of the pipe and by it to
descend to the burner. The pipe terminates in a small bulb about ten inches below
the reflector and into this bulb the gas nipples usually three in number are set,
somewhat obliquely so that when the gas is ignited at the nipples the gas flames
heat the pipe which they surround but without playing directly upon it.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hercunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation of a gas burner and apparatus in accordance with my
invention.
Figure 2 is a vertical section of the same.
a is the gas pipe, it passes down centrally within a chimney to which it is
attached by the radial pipes cl 2. Around the chimney is the naphthaline receiver
and d is the reflector which forms the bottom of the receiver. The top of the
naphthaline receiver e is conveniently conical as shown and is provided with a filling
plug e. The pipe & admits gas into the receiver and the pipe c² allows it to escape
again and pass to the burners. The pipes c¹ e² also serve to support and to carry
the naphthaline receiver. f is a bulb on the lower end of the gas pipe and yg are
gas nipples screwed into this bulb.
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 1
claim is :-
1. The combination of parts consisting of the gas pipe and the chimney
surrounding the gas pipe the receiver around the chimney and the reflector forming
the bottom of the receiver; the radial pipes connecting the gas pipe with the
receiver and serving both to support it and to convey the gas into and from it and
the gas nipples around the gas pipe at its lower end.
2. Gas burners with apparatus for naphthalising gas substantially as described.
