PROVISIONAL SPECIFICATION.
A New Burner, Blowpipe, or Bunsen Lamp, namely, an Appliance
for Burning a Mixture of Air and Gas or Inflammable Vapours
for the Production of Intense Incandescence of Mineral
Substances Employed for Incandescent Gas Lamps, known by the
name of "Auer Lamps," or "Von Welsbach," or other analogous
Lamps.
I, JOSEPH DE BROUWER, Manager of The Bruges Gas Works, at Bruges,
Belgium, do hereby declare the nature of this invention to be as follows:-
The object of this invention is a gas burner in which the air is brought to it
under pressure (by forcing) and draws the gas or inflammable vapours along with
it, this being the reverse of burners at present in use in which the gas only is
under pressure, the gas having to draw the necessary air along with it for the
mixture.
By forcing the air, I produce the following effects :
1. A more complete admixture of the air with the gas or the inflammable
vapours.
2. A more intense current or flow, thus bringing a larger amount of gas and
air to an Auer lamp than with the systems at present employed.
3. As results of this double effect; a, a flame of higher temperature is
produced, b, a greater quantity of useful heat; c, a blowpipe or Bunsen burner in
which back flashing of the flame (that is to say, the gas taking fire in contact with
the air at its exit from the supply pipe) is prevented.
When applied to an Auer or other similar lamp, the effect. produced by my
burner is to raise the mineral substances to be rendered incandescent to a very high
temperature, also a larger amount or surface of these substances to a like tempera-
ture, resulting in considerably more light than would be produced from a lamp of
the same kind fitted with oue of the burners at present employed.
A second effect is to dispense with the use of mica or glass chimneys which are
indispensable for the ordinary incandescent gas lamps.
The apparatus is shown in the annexed drawing. It consists of a cylindrical
tube a swelled out or enlarged at its base and closed by a diaphragm e provided
with holes d, d, the air pipe b passes through the middle of the diaphragm, the
gas supply pipe c passes through the cylinder a a little above the end of the
air pipe.
The supply of air and of gas is controlled by taps or regulators in the usual
way.
The Auer lamp or the substances for producing the incandescent light are fitted
to the upper part of the cylinder a by the customary means.
The patent does not cover any special details of the drawing, nor of the
description as regards the shape of the cylinder a, nor the exact position of the air
and gas tubes and c, nor the provision of holes d, d.
Dated this 1st day of November 1895.

(
I, JOSEPH DE BROUWER, Manager of The Bruges Gas Works, at Bruges,
Belgium, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement :-
The object of this invention is a gas burner in which the air is brought to it under
pressure (by forcing) and draws the gas or inflammable vapours along with it, this
being the reverse of burners at present in use in which the gas only is under
pressure, the gas having to draw the necessary air along with it for the mixture.
By forcing the air, I produce the following effects :-
1. A more complete admixture of the air with the gas or the inflammable
vapours.
2. A more intense current or flow, thus bringing a larger amount of gas and air
to an Auer lamp than with the systems at present employed.
3. As results of this double effect; a, a flame of higher temperature is produced.
b, a greater quantity of useful heat; c, a blowpipe or Bunsen burner in which back
flashing of the flame (that is to say, the gas taking fire in contact with the air at
its exit from the supply pipe) is prevented.
When applied to an Auer or other similar lamp, the effect produced by my
burner is to raise the mineral substances to be rendered incandescent to a very
high temperature, also a larger amount or surface of these substances to a like
temperature, resulting in considerably more light than would be produced from a
lamp of the same kind fitted with one of the burners at present employed.
A second effect is to dispense with the use of mica or glass chimneys, which are
indispensable for the ordinary incandescent gas lamps.
The apparatus is shown in the annexed drawing. It consists of a cylindrical
tube a swelled out or enlarged at its base and closed by a diaphragm e provided
with holes d, d, the air pipe b passes through the middle of the diaphragm, the
gas supply pipe c passes through the cylinder a a little above the end of the
air pipe.
The supply of air and of gas is controlled by taps or regulators in the usual
way.
The Auer lamp or the substances for producing the incandescent light are fitted
'to the upper part of the cylinder a by the customary means.
:
The patent does not cover any special details of the drawing, nor of the
description as regards the shape of the cylinder a, nor the exact position of the
air and gas tubes b and c, nor the provision of holes d, d.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The employment in connection with lamps for lighting by incandescence of
mineral substances, of a blowpipe or Bunsen burner in which the gaseous mixture
and the flame are produced by forcing the air into an apparatus such as that shown
in the drawing.

page_text: 2. In combination with an atmospheric or Bunsen burner, a perforated
diaphragm e, an air nozzle b therethrough, and a gas nipple cat right angles from
an enlarged diameter base of tube a, substantially as represented in the drawing
for the purpose described.
