PROVISIONAL SPECIFICATION.
Improvements in Atmospheric Gas Burners.
I HENRY Cox Junior of 123 Pall Mall London in the County of Middlesex Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
This improvement has for its object the further proper blending and expansion
of gas with common air after passing from my improved atmospheric gas regu-
lating tap.
.
I carry my invention into effect by means of a pipe or tube of a suitable length
and diameter which acts as an amalgamator to this pipe or tube, another pipe or
tube is attached of a suitable length and of a suitable increased diameter for the
purposes of expansion of the gas and common air before passing for ignition at
the burner or burners,
When the flame has been burning for a short time the expansion chamber
becomes heated and the common air and gas in passing through the expansion
chamber is thereby heated and expanded on the passage to the burner or burners
before ignition.

COMPLETE SPECIFICATION.
Improvements in Atmospheric Gas Burners.
I HENRY Cox Junior of 123 Pall Mall in the County of Middlesex Gas Engineer
do hereby declare the nature of my Invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:
My Invention has for its object to provide in. connection with atmospheric gas
burners means for ensuring proper blending and expansion of the mixture of gas
and air before it reaches the burner.
I will describe my Invention with reference to the accompanying Drawings
which shew its application to air and gas inlets arranged to be simultaneously
proportionately adjusted as, and for the purpose described in the Specification of
Letters Patent No. 1634 granted to me as of the 3rd day of February 1888-
Figure 1 is an elevation Figure 2 a vertical section and Figure 3 a transverse
section on the line 1. 2. Figure 1.
A and B are the outer and inner casings perforated at a and b, G the gas
supply pipe, D the gas plug or tap and H the gas inlet pipe leading gas into the
chamber C to mix with the air-E are arms connecting the gas tap with the
casing B. These parts are or may be the same as those described in the Specifi-
cation of my aforesaid Patent-but I provide between the air and gas inlets and
burner first a contraction and then an enlargement or chamber of greater capacity
in which the mixture of gas and air expands before it passes to the burner and
as the mixture becomes comparatively quiescent in this chamber it passes steadily
and quietly to the burner and is more thoroughly burned and the flame is steadier
than would otherwise be the case.
The said enlargement or chamber is shewn in the drawing as being constituted
by a tube L of larger diameter secured at one end to the contracted passage or
tube K leading from the chamber C which passage or tube K acts as an amalga-
mator for the gas and air before the mixture passes into the enlargement Lin
which after it has expanded and become quiescent it passes to the burner M in a
steady manner best suited to secure proper consumption of the gas.

page_text: After the flame has been burning for a short time the expansion chamber L
becomes heated and the mixture of gas and air in passing through the said chamber
is heated as well as expanded.
I do not limit myself to the precise forms of, the several, parts as shewn in the
Drawing.

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.
First In connection with atmospheric gas burners an enlargement or expansion
chamber I between the burner and the gas and air supply substantially as and
for the purpose hereinbefore described.
Second In connection with atmospheric gas burners the combination of a con-
tracted tube or passage K and an enlargement or expansion chamber L between
the burner and the gas and air inlets substantially as and for the purposes herein-
before described.
Third The combination with an atmospheric gas burner of a valve or tap
arranged to give simultaneous adjustment in due proportion of the gas and air
inlets and an enlargement or expansion chamber between the said gas and air
inlets and the burner substantially as herein before described.
Fourth The combination with an atmospheric gas burner of a valve or tap
arranged to give simultaneous adjustment in due proportion of the gas and air
inlets, a contracted passage or tube and an enlargement or expansion chamber
between the said gas and air inlets and the burner substantially as hereinbefore
described.
Fifth The arrangement and combination of parts as a whole constituting an
atmospheric gas burner substantially as herein before described and..shewn in the
accompanying Drawings.
