Improvements in and relating to Gas Burners for Heating Purposes.
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
Fontaines-sur-Saône, Rhône, in the Republic of France) to be as follows:-
The invention relates to a new or improved gas heating-apparatus enabling low
pressure gas to be burnt with admission of air and particularly applicable to
carburetted air.
When it is desired to burn low pressure gases in known gas heating-apparatus,
based on the principle of Bunsen burners, the supply of air is no longer produced
under sufficient conditions, the flame remains illuminating, and further there
flows only a supply of gas which is too weak to feed the burners normally.
The invention has for its object an arrangement of gas heating-apparatus
designed especially to burn these low pressure gases.
The invention is illustrated in the accompanying drawings in which Fig. 1 is a
vertical section, and Fig. 2 a plan partly in section.
In the new style of gas heating-apparatus a part of the arrangement adopted
in the Bunsen burner is utilized, namely, the flow of the gas through a conical
ajutage A, Fig. 2, into a larger tube B, formed with openings D, which can by
means of a movable sleeve E be more or less closed, but besides the diameter of
the ajutage A being greater than in gas heating-apparatus burning gas at
ordinary high pressure, the flow of air through the openings D is no longer due
to the pressure of the gas, as this latter is almost of no account, but rather to the
combustion of the gas itself by means of special burners.
These burners, which may be varied in number according to the effect to be
obtained, are attached to a main conduit H serving to receive the gas, they are
formed of tubes F of wire gauze having very fine openings or meshes, arranged
parallel with each other and are fixed by one of their ends around the tubes B
having the air supply apertures and are closed at their other ends by a hollow
stopper G.
In these conditions the gas burns above the wire gauze tubes and its combus-
tion determines a supply of air on the one hand through the holes of the wire
gauze and, on the other hand, through the openings 1 exterior of the gas heating-
apparatus. This latter supply of air not being produced by the jet of gas leaving
the ajutage, but rather aiding the outflow of the said gas. The mixture of gas
and air is regularly effected and burns with a very hot blueish flame.
As metallic gauze ultimately oxidizes, a simple construction has been adopted
enabling the worn out gauzes to be readily removed and to be replaced by new
ones without being obliged to take the gas heating-apparatus to pieces.
For this purpose the wire gauze tubes F are held at one end on the tubes B by
movable sleeves I, which cover them, whilst their other ends enter short tubes J

their interior. The middle burner Fig. 2 shows this mode of dismounting..
It will be understood that in applying the same principle, the gas heating-
apparatus may be made of various forms and dimensions.

Improvements in and relating to Gas Burners for Heating Purposes.
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
Fontaines-sur-Saône, 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 invention relates to a new or improved gas heating-apparatus enabling low
pressure gas to be burnt with admission of air and particularly applicable to
carburetted air.
When it is desired to burn low pressure gases in known gas heating-apparatus,
based on the principle of Bunsen burners, the suction of air is no longer sufficient
the flame remains illuminating, and further there flows only a supply of gas
which is too small to feed the burners normally.
The invention has for its object an arrangement of gas heating-apparatus
designed especially to burn these low pressure gases.
The invention is illustrated in the drawings accompanying my Provisional Speci-
fication in which Fig. 1 is a vertical section, and Fig. 2 a plan partly in section.
In the new style of gas-heating-apparatus a part of the arrangement adopted
in the Bunsen burner is utilized, namely, the flow of the gas through a conical
ajutage A, Fig. 2, into a larger tube B, formed with openings D, which can, by
means of a movable sleeve E, be more or less closed, but besides the diameter of
the ajutage A being greater than in gas heating-apparatus burning gas at
ordinary high pressure, the flow of air through the openings D is no longer due
to the pressure of the gas, as this latter is almost of no account, but it is rather
due to the combustion of the gas itself by means of special burners.
These burners, which may be varied in number according to the effect to be
obtained, are attached to a main conduit H serving to receive the gas from the main
they are formed of tubes F of wire gauze having very fine openings or meshes,
arranged parallel with each other and are fixed by one of their ends around the
tubes B having the air supply apertures and are closed at their other ends by a
hollow stopper G.
In these conditions the gas burns above the wire gauze tubes and its combus-
tion determines a supply of air partly through the holes of the wire gauze
and partly through the openings D exterior of the gas heating-
apparatus. This latter supply of air not being produced by the jet of gas leaving
the ajutage, but rather aiding the outflow of the said gas. The mixture of gas
and air is regularly effected and burns with a very hot blueish flame.
As metallic gauze ultimately oxidizes, a simple construction has been adopted
enabling the worn out gauzes to be readily removed and to be replaced by new
ones without being obliged to take the gas heating-apparatus to pieces. .

page_text: For this purpose the wire gauze tubes are held at one end on the tubes B by
movable sleeves I, which cover them whilst their other ends enter short tubes J
in the interior of which they can be fixed by the hollow stoppers G, entering
their interior. The middle burner Fig. 2 shows this mode of dismounting.
It will be understood that in applying the same principle, the gas heating-
apparatus may be made of various forms and dimensions.
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 gas heating-apparatus consuming low pressure gases characterised by
the supply of air being obtained by means of the combustion of the gas burning
on the surface of one or several wire gauze tubes of suitable form arranged hori
zontally or vertically the said supply of air being obtained partly through the
wire gauze and partly through exterior openings arranged around the jets
supplying the gas to the burners, substantially as herein set forth.
2. The combination with gas burners for heating purposes as above claimed
of a movable sleeve to regulate the size of the openings in the tube B and the
means employed to fix the wire gauze tube in position with facility for renewal
thereof, substantially as herein set forth.
