Improvements in Gas Burners or Lamps.
We, FRANZ MANOSCHEK, and RUDOLF MANOSCHEK, both of the firm Franz
Manoschek of VI Wallgasse No. 27, Vienna, Austria, Manufacturers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to gas burners or lamps of the kind in which the air
supply to the flame is heated in the first instance by the heat of the products of
combustion.
According to the present invention we provide such burners or lamps with one
or more chambers forming an air reservoir into which the outer air passes on its
way to the flame and in which it is heated by the products of combustion before
passing against both sides of the flame.
For this purpose there is formed above the burner a chamber or chambers of
comparatively large capacity, from which pass firstly branch tubes in an upward
sloping direction connected at their outer ends to a casing surrounding the
chamber so that the outer air enters such branch tubes from the outer surface of
the casing; secondly, the chamber has other branch tubes sloping in a downward
direction and having their ends also connected to the casing, so that the air that had
previously entered the casing through the upper branches and become heated therein,
issues through the lower branches to the flame of the burner.
According to one arrangement, there is also a central downward directed opening
to the air reservoir, through which a portion of the air descends so as to come in
contact with the inner surface of the flame, while that issuing from the lateral openings
comes in contact with the outer surface of the flame.
According to another arrangement, the central opening of the air reservoir is
dispensed with, and, the burner being made of ring shape, the air passing down from
the lateral openings is made to pass partly against the outer surface of the flame and
partly through the central space of the annular burner to the inner surface of the
Hame.
The products of combustion pass up from the flame through the space between the
central air reservoir and the outer casing, where it imparts its heat partly to the outer
surface of the air reservoir and partly to the branch tubes crossing the said space,
through which the air passes into and out of the reservoir, thereby heating the air as
it passes through.
In the above described arrangement with ring shaped burner, the above described
space may have a central downward directed opening which is surrounded by the ring
shaped burner, so that the flame from the latter is directed inwards towards such
opening. In the other arrangement, the opening of the said space surrounds the
before mentioned central passage from the air reservoir.
The upper end of the outer casing carries a chimney flue, and its upper part is
surrounded by a hood having openings through which the air enters the inlet branch
tubes to the reservoir.

Improvements in Gas Burners or Lamps.
We, FRANZ MANOSCHEK and RUDOLF MANOSCHEK, both of the firm Franz
Manoschek, of VI Wallgasse No. 27 Vienna Austria Manufacturers, 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:-
This Invention relates to gas burners or lamps of the kind in which the air
supply to the flame is heated in the first instance by the heat of the products of
combustion.
According to the present invention we provide such burners or lamps with one or
more chambers forming an air reservoir into which the outer air passes on its way to
the flame, and in which it is heated by the products of combustion, before passing
against both sides of the flame.
For this purpose there is formed above the burner a chamber or chambers of
comparatively large capacity, from which pass firstly branch tubes in an upward
sloping direction connected at their outer ends to a casing surrounding the chamber
so that the outer air enters such branch tubes from the outer surface of the casing:
secondly, the chamber has other branch tubes sloping in a downward direction, and
having their ends also connected to the casing, so that the air that had previously
entered the casing through the upper branches and become heated therein, issues
through the lower branches to the flame of the burner.
The accompanying drawing shews various arrangements of our above described
invention.
Figure 1 shews a vertical section of a lamp with outward burning flame supplied
from above. Figure 1ª shews a sectional plan.
Figure 2 shews a vertical section of a lamp with inward burning flame, Figures 3
and 4 shew modification in which the gas supply is from below. In all figures the
same letters of reference indicate the same parts.
The drawings shew, by way of example constructions in which only one air chamber
is employed, but as before stated, there may be two or more of these.
Under the outer hood of the lamp openings a a are formed in the casing m, through
which the outer air is admitted.
The openings are connected by tubes or passages e to the air chamber d into which
consequently the outer air passes.
From this chamber the air passes through other tubes f and over the reflector c to
the outside of the flame, and as shewn at Figures 1 and 3; also through a central
tube g to the inside of the flame. The direction of the air currents is shewn in all
cases by arrows.
In the arrangement shewn at Figures 2 and 4, the air passes in the same manner
as at Figures 1 and 3, but the air supply issuing from d through the tubes ff,
passes both to the inner and outer surfaces of the flame, there being no central
supply tube.
The hot combustion gases passing away from the flame are caused to come
intimately in contact with the outer surfaces of the air chamber.d, and of the tubes e fig
and thus impart the greater portion of their heat to the air supply passing through
these, before escaping through the chimney b. By the employment of one or more
central air chambers according to the present invention, a comparatively large body of
air is maintained for some time in contact with the surfaces heated by the gases, and
the air can thus attain a higher degree of heat, than when merely flowing rapidly
through a series of passages as in the arrangements heretofore employed, resulting in
a higher degree of luminosity for the flame."
In the arrangements shewn at Figures 1 and 3, the air tube g is provided with a
head which directs the air against the flame, at Figure 2 the tube through which
the combustion gases escape is also provided with a head for giving the necessary

page_text: form to the inward burning flame, and at Figure 4 where there is no central tube a
shield is provided for the same purpose. The burner i may either be of the rosette
shape as at Figures 1 and 3, or of annular shape as at Figures 2 and 4.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The use in combination with gas lamps having a heated air supply, of one or more
chambers d, situated centrally in the lamp, which communicate with the outer air by
branch tubes e. e, and with the burner by tubes f, and g, in which chamber or chambers
and tubes the air supply becomes heated by the combustion gases from the burner,
on its way to the latter, substantially as herein described.
2. The modified arrangement of the air chamber referred to in the preceding claim
wherein the central air tube g is dispensed with and the air supply from the tubes f is
made to pass in contact with both the inner and the outer surfaces of the flame,
substantially as described with reference to Figures 2 and 4 of the drawings.
