I, BENJAMIN FELIX ELDERTON of No 111 Albion Road, Stoke Newington, in
the County of Middlesex Engineer, do hereby declare the nature of my Invention
for IMPROVEMENTS IN THE TREATMENT OF COAL GAS, AND APPARATUS FOR
INCREASING ITS BRILLIANCY FOR ILLUMINATING PURPOSES to be as follows:-
My Invention relates to the treatment of ordinary Coal Gas for illuminating
purposes, by rarifying it by means of heat and enriching it by admixture of other
combustible gases obtained by fusion of solidified napthaline or petroleum wax.
The manner in which I perform my invention is as follows:-I attach to the arm
of an ordinary gas-bracket or gasalier, at a convenient point, a retort or cylinder,
through which I pass a coil of pipe to convey the gas to the point of combustion,
in manner shewn in the annexed drawing.
The flame being in close proximity to the pipe which supports the chimney-glass,
heats the Coal Gas in its passage, and by rarification procures more complete
combustion and illuminating power. For the purpose of further increasing its
brilliancy, I introduce solidified napthaline or petroleum wax into the retort or
cylinder, through an opening adjusted by a screw plug. The superheated or rarified
Coal Gas passing through the thread of pipe in the retort or cylinder, fuzes and
vaporises the solidified napthaline or petroleum wax, which vapor mixes with the
Coal Gas and creates intense brilliancy at the point of combustion.
My invention is readily applicable to flat flame burners by simply lowering the
circular pipe which in the annexed drawing is shown as supporting the chimney-
ginsя.
I adapt my invention to clusters of lights by conveniently adjusting as many
arms as may be desired to one central retort or cylinder of the nature before
described.

to the burner G, where it will be consumed. Directly the burner G is lighted, the
gas contained in the pipe D, which surrounds the chimney-glass E, becomes greatly
heated and rarified, and still retaining its heat, passes downwards through the coil
of pipe D, which it heats, thereby causing the petroleum wax B in the retort to
melt and let off a rich gas, which mixes with the rarified gas and then passes
through the short piece of pipe F to the burner G, where it will be consumed.
Having thus described the nature of my invention and in what manner the
same is to be performed, I claim the apparatus and method substantially herein
described for heating and rarifying Coal Gas before combustion, combined with the
fuzing of solidified napthaline or petroleum wax by means of such heated gas.

I BENJAMIN FELIX ELDERTON of 111, Albion Road, Stoke Newington, in the
County of Middlesex Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN THE TREATMENT OF COAL GAS AND APPARATUS FOR INCREASING
ITS BRILLIANCY FOR ILLUMINATING PURPOSES and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
The object of this Invention is the improved treatment of ordinary Coal Gas for
illuminating purposes by rarifying it by means of heat and enriching it by admixture
of other combustible gases obtained by vaporization of solidified napthaline or
petroleum wax or other hydro-carbons.
The manner in which I perform my invention is as follows:-
I attach to the arm of an ordinary gas bracket or gasalier at a convenient point
a retort or cylinder through which I pass a coil of pipe [or other convenient form]
to convey the gas to the point of combustion in inanner shewn in the annexed
drawing [Fig 1]-as applied to an Argand burner-The flame being in close
proximity to the pipe which supports the chimney glass heats the coal gas in its
passage, and by rarification procures more complete combustion-For the purpose
of increasing its brilliancy, I introduce solidified napthaline or petroleum wax, or
other hydrocarbons, into the retort or cylinder through an opening adjusted by a
screw plug. The superheated or rarified coal gas passing through the coil of pipe
in the retort or cylinder vaporizes the solidified napthaline or petroleum wax or
other bydrocarbons which vapor mixes with the coal gas and creates intense
brilliancy at the point of combustion.
The application of my invention to flat flame burners is shewn in the annexed
drawing Fig 2-For this purpose the pipe (which in the case of an Argand burner
is used as a support for the chimney glass) is placed, so as to surround the flame,
close to the point of combustion, and for the purpose of obtaining greater heat such
pipe is bent into the form of a double are between which the flame spreads in a
line parallel to the sides of the are the points of which are connected with the
retort or cylinder as shewn in the drawing.
I adapt my invention to clusters of lights or gasaliers by conveniently adjusting
as many arms as may be desired to ono central retort or cylinder, or by fixing to
each arm a small retort or cylinder of the nature before described.
DESCRIPTION OF DRAWINGS.
Fig: 1, is a drawing shewing the application of this invention to Argand burners.
The oval A is the retort or cylinder filled with solidified napthaline or petroleum
wax or other hydrocarbons B, introduced at screw plug C.-D, is the coal gas
supply pipe which passes up through the retort A, and then is bent upwards so as
and then down into the retort. A through

page_text: almost to the bottom. It is then bent upwards to the point D D, where the conl
gas enters the body of the retort A, and then passes through the short piece of
pipe F, to the burner G, where it will be consumed.
Directly the gas is lighted at the burner G, that contained in the pipo D, which
surrounds the chimney glass E, becomes greatly heated and rarified and still
retaining its heat passes through the coil of pipe D, which it heats, thereby causing
the solidified napthaline or petroleum wax or other hydrocarbons B, in the retort
to let off a rich gas which mixes with the rarified coal gas and then passes through
the short piece of pipe F, to the burner G, where it will be consumed.

burners; H, is the pipe in the form of a double arc surrounding the flame.

Fig 4-Is a cross section of the same.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, and being aware
that patents have been granted on prior applications for the enrichment of gas by
the admixture of hydro-carbon vapour, and inter alia by the apparatus & method
described in the Specification of James Livesey N° 1331 of the year 1881 I hereby
doclaro that I make no general claim to the enriching of coal gas by admixture
of vaporized solidified napthaline or petroleum wax or other hydrocarbons nor do
I claim the fusing and vapourizing of solidified naphtaline or petroleum wax or
other hydrocarbons in the retort or cylinder herein before described, by means of
heat conveyed to such hydro-carbons by metallic conduction, but what I claim is
The Apparatus and method substantially herein described for heating and
rarifying coal gas before combustion, and vaporizing such hydrocarbons by means
of circulating pipes filled with heated gas contained in such circulating pipes.

of increasing its brilliancy, I introduce solidified napthaline or petroleum wax, or
other hydrocarbons, into the retort or cylinder through an opening adjusted by a
scrow plug. The superheated or rarified coal gas passing through the coil of pipo
in the retort or cylinder vaporizes the solidified napthaline or petroleum wax or
other hydrocarbons which vapor mixes with the coal gas and creates intense
brilliancy at the point of combustion.
