GAS-BURNERS."
"IMPROVEMENTS I
The object of this Invention is to construct a combination of gas burners which
shall give a greater luminosity than when such burners are used separately. In
carrying out my Invention I construct the lower portion of the burner in two
parts, one being an enlarged chamber (hereinafter called the container,) for
containing a supply of gas, which becoming heated therein by conduction is
rarified and expanded, and is so better prepared for burning, whilst such container
also forms a support and feeder for a pair of burners, each supplied therefrom by a
separate passage, and the flames of which burners in issuing from their respective
orifices, combine together, and so give out a broad flat flame of great luminosity and
perfect combustion. The other part of this improved burner consists of the lower,
portion of the ordinary Bronner tip, and which I employ to check the supply of gas
entering the burner,
Another modification of this Invention consists of the Bronner tip above-
mentioned in combination with a pair of burners, each supplied with gas by a
separate passage, as above described.

GAS BURNERS."
"IMPROVEMENTS IN
The object of this Invention is to construct a combination of gas burners which
shall give a greater luminosity than when such burners are used separately. In
carrying out my Invention I construct the lower portion of the burner in two parts,
one being an enlarged chamber (hereinafter called the container,) for containing a
supply of gas, which becoming heated therein by conduction is rarified and
expanded, and is so better prepared for burning, whilst such container also forms a
support and feeder for, by preference, a pair of burners, the flames of which, in
issuing from their respective orifices, combine together and so give out a broad flat
flame of great luminosity and perfect combustion. The other part of this improved
burner consists of the lower portion of the ordinary Bronner tip, and which I
employ to check the supply of gas entering the burner. Another modification of
this Invention consists of the Bronuer tip above mentioned in combination with a
pair of burners, each supplied with gas by a separate passage, as above described.
And in order that this my said Invention may be the more readily understood
and carried into practical effect, I have hereunto annexed a Drawing illustrative of
my improvements, and will now proceed to describe the same, reference being
had to the figures and letters of reference marked thereon. Figure 1 is a side
sectional view, Figure 2 a front view, and Figure 3 a plan of a gas burner
constructed in accordance with my Invention, and Figure 4 is a perspective view of
the same burner, shewing the flames issuing from their respective orifices to form
one combined flame of great luminosity. Figure 5 is a front view, and Figure 6 a
sectional view, and Figure 7 a plan of an Argand gas burner, having my improve-
ments applied. In Figures 1 to 4 A is the enlarged chamber or container formed, by
preference, of metal, and the lower extremity of which terminates in a pair of
screws, the upper one to receive the globe gallery, and the lower one to, screw into
the gas fitting. B, B, are a pair of shallow gas burners which screw into or are
otherwise connected to the top of the container A, in order that the heat may be
most effectually conducted or reflected to the chamber A, and thus by beating the
gas passing through such chamber to improve the luminosity of the combined
flames. It will he observed that the two flames combine together to form one
single flat flame, and the effect of this combination, added to the effect of heating
the gas before it issues, together with the increased consumption of oxygen, is to
produce a brilliant flame of great luminosity and of perfect combustion. In some
cases I employ a single burner in combination with my improved container to
produce an approximated similar result. The Argand-burner illustrated in Figures
5 and 6 and 7 is upon the same principle as the foregoing, being a combination of a
single ordinary Argand burner and my improved chamber or container. Instead of
having the container or heating chamber near to the gas burner, and to be heated
by conduction as aforesaid, it will be obvious that the same may be at any distance
therefrom, say, anywhere between the gas-meter and the gas fittings, and in this
case such chamber would be heated either by a separate gas jet or jets, or steam o
hot water may be caused to circulate round the outside of the container for the
purpose of heating the gas passing through. Having thus particularly described
the nature of this my said Invention, together with the best methods with which
I am acquainted for carrying the same into practical effect, I wish it to be distinctly
understood that I make no claim to the use of a pair of burners to form a combined
flame, nor do I confine myself to the precise details, relative proportions, o

page_text: dimensions hereinbefore described and illustrated on the accompanying Drawing, as
the same may be considerably varied without departing from the Invention, but
what I claim is,―
1st. The improved method of increasing the luminosity of gas jets, substantially
as herein before described.
2nd. The use and application of an enlarged chamber or container for heating the
gas prior to its issuing from the gas burner, substantially as and for the purpose
hereinbefore described and illustrated on the accompanying Drawing.
3rd. Combining one or two gas burners with my improved chamber or container,
substantially as and for the purpose hereinbefore described and illustrated on the
accompanying Drawing.
In witness whereof, I, the said Thomas Heron, have hereunto set my hand and
Beal, this Twenty eighth day of April, in the year of our Lord 1880.
