I JAMES LEWIS of 153 Brockley Road, Brockley, in the County' of Surrey,
Engineer do hereby declare the nature of my Invention for "IMPROVEMENTS IN
GAS BURNERS FOR CONSUMING A MIXTURE OF GAS AND AIR FOR ILLUMINATING
AND HEATING PURPOSES to be as follows:-
"
My present improvements in gas burners for consuming a mixture of gas and
air relate to that class of gas burners described in the Specification of Letters
Patent dated 8th January 1883 N° 105 in which induced currents of air were
introduced to the pipe or chamber below the platinum wire gauze burner to mix
with gas under pressure before reaching the burner.
According to my present improvements the induced currents of air are so
arranged as to effect the combustion of the gas in the burner at its normal or even
below its normal pressure from the supply pipes.
For this purpose I mount the platinum wire gauze burner upon a cone shaped
inlet passage over the gas supply pipe the bottom of the cone being open to the
atinosphere. This cone is surrounded by a chimney an annular space being left
between it and the bottom of the cone for the admission of air.
Around the bottom of the chimney and the inlet cone another shorter tube is or
may be mounted with a space between them for the admission of air which becomes
heated in its passage between it and the chimney to the burner. In large sized
burners this outer short tube may be dispensed with.
Below the inlet cone and around the gas supply pipe perforated plates are
arranged also for the admission of air to the inlet cone and burner. These plates
are so arranged that the perforations or openings can be closed or partially closed
to regulate the admission of air to the burner.
Above or around the upper end of the chimney previously referred to another
chimney of larger diameter is mounted with a space between the two for the
admission of a current of air which acts to increase the force of the other induced
currents of air to the burner.

Engineer, do hereby declare the nature of my Invention for "IMPROVEMENTS
IN GAS BURNERS FOR CONSUMING A MIXTURE OF GAS AND AIR. FOR ILLUMINATING
AND HEATING PURPOSES" and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:--
My present improvements in gas burners for consuming a mixture of gas and
air relate to that class of gas burners described in the Specification of Letters
Patent dated 8th January 1883 N° 105 in which induced currents of air were
introduced to the pipe or chamber below the. platinum wire gauze,burner to mix
with gas under pressure before reaching the burner.
According to my present improvements the induced currents of air are so
arranged as to effect the combustion of the gas in the burner at its normal or éven
below its normal pressure from the supply pipes.
For this purpose
I'mount the platinum wire gauze burner upon a cone shaped
inlet passage over the gas supply pipe the bottom of the cone being open to the
atmosphere. This cone is surrounded by a chimney an annular space being left
between it and the bottom of the cone for the admission of air..
Around the bottom of the chimney and the inlet cone another shorter tube is
or may be mounted with a space between them for the admission of air which
becomes heated in its passage between it and the chimney to the burner. In large
sized burners. this outer short tube may be dispensed with..
Below the inlet cone and around the gas supply pipe perforated plates are
arranged also for the admission of air to the inlet cone and burner. These plates
are so arranged that the perforations or openings can be closed or partially closed
to regulate the admission of air to, the burner.
Above or around the upper end of the chimney previously, referred to another
chimney of larger diameter is mounted with a space between the two for the
admission of a current of air which acts to increase the force of the other induced
eurrents of air to the burner.
And in order that my. Invention may be clearly understood and readily carried
into practice I will proceed to describe the. Drawings hereto annexed which show
two gas burners arranged to act in accordance with my Invention.

DESCRIPTION OF THE DRAWINGS.
Figure 1 is a vertical section of a gas burner suitably arranged in accordance
with my improvements for consuming a mixture of ordinary or other illuminating
gas and air.
a is the platinum wire gauze cap which is rendered incandescent by
the combustion of the mixture of gas and air. a is a connecting piece of steatite
or other suitable non-conducting material and a² is a cone-shaped chamber
(mounted upon the gas supply pipe b) in which the gas and air are mixed in their
passage to the burner a the bottom of the cone being open to the atmosphere.
The cone and burner a is surrounded by the chimney or tube c, another shorter
tube d, being supported around the lower part of the tube c, leaving an annular
space between the tubes c and d for the admission of air as indicated by the
arrows to the underside of the cone the air being heated in its passage down the
annular space d¹ to the burner.
e el are perforated plates which support the tubes c and d the perforations being
so arranged that the spaces between the perforations of one plate cover or partially

page_text: cover the perforations in the other plate and by giving a partial rotation to the
lower plate e¹ the passage of air through the perforations can be regulated or cut
off altogether and thus regulate the supply of air to the underside of the cone a*
when required for burners of large size. e is a disc of wire gauze or perforated
metal. is another tube of larger diameter than the upper end of the tube cover
which it is mounted or suspended an annular space being left between the two for
the admission of air so as to increase the draft of air to the burner a which can be
regulated by raising or lowering the tube f.
Figure 2 shows a vertical section of a similar burner corresponding parts being
marked with similar letters of reference the tube d in this arrangement being
dispensed with.
The globe and chimney c (which may be an ordinary lamp or transparent
chamber of any suitable shape) in this arrangement is supported on the ring or
other support b' to which the cone a² is fixed, an air tight joint being made with
india rubber or other suitable material between the ring or support b¹ and globe
(or lamp chamber) c where the latter is supported when the burners are of
comparatively large size. is a tube (or perforated screen) of wire gauze for the
admission of air to the cone a² and burner and e e¹ are perforated plates (such as
previously described) for regulating the admission of air to the burner as inay be
required when the burners are of large size.
From the previous description of the two arrangements of burners for consuming
a mixture of gas and atmospheric air in accordance with my Invention it will be
evident to any one acquainted with the arrangement and construction of gas burners
that gas burners of this improved character may be considerably varied in their
arrangement and combination of parts without departing from the main object of
my Invention which is the so arranging the strength of the relative currents of air
and gas to supply the burner as to render the platinum wire gauze incandescent for
producing light and heat.
Having thus described the nature of my Invention and the manner of performing
or carrying the same into practice I would remark that I make no claim to any of
the parts separately which are well known and in common use.
But what I claim is-
1
First. The improved arrangement and construction of gas burners for consuming
a mixture of gas and atmospheric air by means of induced currents of air of
sufficient volume and strength produced by means of a combination of chimneys or
tubes to cause a platinum wire gauze or perforated cap such as a to become
incandescent for producing light and heat substantially in the manner and for
the 'purpose herein before fully described and represented in the Drawings hereto
annexed.
Second. I claim the improved arrangement and combination of parts constituting
the improved gas burners for burning a mixture of gas and air combined such
burners being arranged to act substantially in the manner and for the purpose
herein before fully described and represented in the Drawings hereto annexed.
