Improvements in Gas Burners.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from La Société Anonyme des Fontaines à Gaz, of Fon-
taines-sur-Saône, in the Department of Rhône. in the Republic of France),
to be as follows:-
The burner forming the subject of this invention is intended to utilize for
illuminating purposes, gases of very variable composition or obtained under feeble
pressure, such as those arising from the distillation of wood, essences of petroleum,
or special apparatuses such as the gas fountains patented by Bouchaud-Praceiq
The characteristic features of this new buiner are 1, a large section of the
channels which conduct the gas to the burner orifices, this section being in every
case much larger than the total surface of the orifices in order to occasion no loss
of pressure of such gases as already have a very feeble pressure
2, a very extended regulation of the air admission around the burner This
regulation may be made with precision from zero to the maximum quantity
required by the different compositions of gases to be burned
These conditions may be fulfilled by various arrangements, amoung which, those
which do not alter too much the appearance and dimensions of the ordinary burners
are preferred.
The accompanying diawing shows an example in which Fig. 1 18 a section
through the axis of the new burner, Fig 2 is an exterior view in elevation, Fig 3
is a plan view, Figures 4 and 5 are modifications of the arrangement
The burner A is annular, the gas 18 conducted to it by a forked tube CC pre-
ceded by a regulating cock F The maximum opening of this cock and the
section of the forked tube are much larger than the total section of the burner
orifices, so as to be able to buin the gas with the full pressure of the generator
or gas holder
The lower part of the burner 18 surrounded by a cylindrical sleeve B, closed at
its lower part, and on the circumference of which are openings 0, 0, for the
admission of air, which passes to the burner through the openings DD made in
the upper part of the sleeve and covered by the cone E reaching to the level of
the burner
By this arrangement the totality of air necessary for combustion passes through
the openings 0, 0, and it suffices to close partially or even entirely these openings,
to regulate combustion
This closing is obtained by means of a ferrule G, of sufficient width encircling
the sleeve B, and capable of sliding on it so as to cover more or less the openings.
In order to render the regulation easy and invariable, the sleeve carries on its
oircumference helicoidal grooves HH in which engage the extremities of as many
screws II fixed to the ferrule G It suffices therefore to turn this ferrule in one
or the other direction to obtain a partial or an entire closing of the openings O

same result The air admission openings may be formed, either on the cylindrical
surface as shown in Fig 4, 01 on the base of the burner as shown in Fig 5

cover them

Improvements in Gas Burners.
I, BENJAMIN JOSEPH BARNARD MILLS, of 23, Southampton Buildings, in the
County of London, Patent Agent, do hereby declare the nature of this invention
(a communication to me from La Société Anonyme des Fontaines à Uaz, of Fon-
taines-sur-Saône, in the Department of Rhône, in the Republic of France),
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement;--
The burner forming the subject of this invention is intended to utilize for
illuminating purposes, gases of very variable composition or obtained under feeble
pressure, such as those arising from the distillation of wood, essences of petroleum,
or special apparatuses such as the gas fountains patented by Bouchaud-Piaceıq.
The characteristic features of this new burner are, 1, a large section of the
channels which conduct the gas to the burner orifices, this section being in every
case much larger than the total surface of the orifices in order to occasion no loss
of pressure of such gases, as already have a very feeble pressure.
2, a very extended regulation of the air admission around the buiner This
regulation may be made with precision from zero to the maximum quantity
required by the different compositions of gases to be burned
These conditions may be fulfilled by various arrangements, among which those
which do not alter too much the appearance and dimensions of the ordinary burners
are preferred.
The drawing accompanying the Provisional Specification shows an example in
which
Fig. 1 is a section through the axis of the new burner, Fig 2 is an exterior
view in elevation; Fig 3 is a plan view; Figures 4 and 5 are modifications of the
arrangement.
The burner A is annular, the gas is conducted to it by a forked tube CC pre-
ceded by a regulating cock F. The maximum opening of this cook and the
section of the forked tube are much larger than the total section of the burner
orifices, so as to be able when required to burn the gas with the full pressure of
the generator or gas holder.
The lower part of the burner is surrounded by a cylindrical sleeve B, closed at
its lower part, and on the circumference of which are openings 0, 0, for the
admission of ail, which passes to the burner through the openings DD made in
the upper part of the sleeve and covered by the cone E reaching to the level of
the burner
By this arrangement, the whole of the air necessary for combustion passes
through the openings 0, 0, and in order to regulate combustion it suffices to
partially or even entirely close these openings
This closing is effected by means of a ferrule G, of sufficient width encircling
the sleeve B, and capable of sliding on it so as to cover more or less the openings.
In order to render the regulation easy and invariable, the sleeve carries on its

page_text: circumference helicoidal grooves HH in which engage the extremities of as many
sciews II fixed to the ferrule G. It will be sufficient therefore to turn this
ferrule in one or the other direction to obtain a partial or an entire closing of
the openings O.
Other arrangements it will be well understood may be adopted for obtaining the
same result. The air admission openings may be formed, either on the cylindrical
surface as shown in Fig 4, or on the base of the burner as shown in Fig. 5
and be closed by a ferrule L or disc M having similar openings and full parts to
cover them.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is;-
-
1 A burner for illumination by means of gases of low pressure and of variable
composition, having very large gas supply channels and provided with a collar
capable of regulating the supply of au, from nothing to a very extended limit
substantially as herein set foith.
2 In a gas burner for illumination by means of gases of low pressure and of
variable composition, the combination of a burner body having gas emission
orifices, very large gas supply channels, a regulating cock formed with a very
large opening, a cylindrical sleeve at the lower part of the burner, closed at its
lower end, air admission orifices around the circumference of said sleeve, openings
in the upper part of said sleeve for the passage of air to the burners, a cone
covering said openings and reaching to the level of the burner, a collar surround-
ing the sleeve and capable of sliding on it so as to regulate the air openings and
means for facilitating the regulation of said collar, substantially as herein set forth
Dated this 13th day of September 1899.
