Improved Regenerative Gas Burner.
I, JACOB HAEUSSLER, Manufacturer of 99 Chaussee Strasse, Berlin, Germany
do hereby declare the nature of my invention and in what manner the same is
performed to be particularly described and ascertained in and by the following
statement :-
It is well known that the illuminating power of a lamp will be considerably
increased by previously heating the air fed to the burner, and the object of the
present invention is to provide means for easily and effectually heating the air fed
to the burner.
In carrying my invention into practice I advantageously conduct the air to the
burner from above and below the same, and for this purpose I arrange below the
said burner a hollow conoidal chamber from the apex of which the said burner
extends upwardly said chamber being provided with perforations around the
burner through which the air passes, and above the burner, concentric to the
same I arrange a second air chamber advantageously of a partially spherical
form, having perforations at its lower part around the burner and communicating
with the outer air. This upper chamber will be heated by the flame of the lamp
when burning and the air passing to the burner through the same will be
consequently heated to a very high degree, causing the lamp to burn with an
intense white flame.
As shown in the accompanying drawing, gas is conducted to the burner a
through the pipe b leading from underneath the base plate of the lamp. Around
the said burner and concentric with the same is a chamber d conoidal in form and
having perforations at the upper part thereof, said chamber communicating with
the outer air through the perforations in the base plate r. The burner a is
provided with horizontal circularly arranged perforations 9 so that the gas will
issue from the same horizontally and burn in the form of a circular flame having
its outward edges curling upwardly.
Above the burner a and also concentric thereto is the upper heating chamber c
which may be centred on the burner by a pin s of the same and is provided at its
upper end with air inlet passages h having their outer ends fixed in a ring m
forming the upper closure to the glass globe n of the lamp. This chamber c is
advantageously partially spherical in form and its lower part is provided with
perforations e which admit the air to the flame. The upper part of the ring m is
adapted to carry the chimney k of the lamp.
The operation of the device is obvious: The flame which continually plays
around the upper chamber c will heat the same to a very high degree and conse-
quently the air passing through the chamber will be heated to a proportionately
high degree before arriving at the flame and thus the latter caused to burn more
intensely and with a perfectly white colour.
In order to prevent outer air currents and draught from influencing the burner
a saucer or plate o is provided underneath the base plate r on which an exterior
lamp globe n may be arranged.
Of particular importance in the present invention is the arrangement of the air
inlet holes in the air chambers c and d whereby the air is distributed equally over
the whole surface of the flame and much more thoroughly and equally heated than
hitherto.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is performed I declare that what I claim is :-
1. The combination with a burner a of a lower air chamber d encircling the
burner and concentric therewith and having perforations at its upper part around
the said burner, and an upper chamber c having its lower part hemispherical in
form and provided with perforations e, said chamber being also arranged concentric
to the burner and communicating at its upper part with the outer air, a base
plate having perforations / and closing the lower end of the lower air chamber
and a globe n enclosing the burner and both chambers, and suitable chimney k
above the upper chamber substantially as described.
2. The combination of a burner a having gas inlet pipe b a lower conoidal chamber
concentric with and enclosing the lower part of the same, perforations around the
burner in the upper part of the chamber da base plater having perforations to
support said chamber, an upper chamber having lower hemispherical part and
concentric with the said burner, upper air inlet pipes to the said chamber and
lower air outlet perforations e around the burner to the same, a ring m to carry the
said chamber and air inlet pipes, a chimney k on the said ring and a globe n
extending from the base plate to the said ring m and enclosing the burner and both
chambers substantially as described.
3. The combination of a burner a having gas inlet pipe band circularly
arranged gas outlet perforations 9 arranged horizontally around the said burner
head, a lower conoidally formed air chamber concentric with and enclosing the
lower part of said burner, perforations, in the upper part of said chamber around
the burner, a base plate r having perforations to support said chamber, an upper
chamber having lower rounded part and arranged concentric with the said
burner, upper air inlet pipes h to the said chamber and lower air outlet perfora-
tions to the same a ring m to carry the said chamber and air inlet pipes a chimney k
on the said ring and globe n extending from the base plate to the said ring m and
enclosing the burner and both chambers substantially as described.
4. The combination of a burner a having gas inlet pipe b, a lower conoidally
formed chamber d concentric with and enclosing the lower part of the said burner,
perforations in the upper part of the said chamber around the burner, a base
plater having perforations / to support said chamber, an upper chamber c having
lower rounded part and concentric with the said burner a pin s on the said burner
to centre the said upper chamber, upper air inlet pipes to the said chamber and
lower air outlet perforations e around the burner, a ring m to carry said burner
and the inlet pipes thereto, a chimney k on said ring, a globe n extending from
the said ring m to the base plate and enclosing both chambers and the burner, and
a plate or saucer o under said burner for the purpose substantially as described and
shown.
