Improvements in Burners.
I, OSCAR BRÜNLER, of Eilenburg, Saxony, Germany, Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement —
My invention has reference to a burner, which will maintain its function even in
compartments, which contain no atmospherical air. Over similar arrangements my
improved burner has the great advantage, that, if gas is employed as fuel, the air
need not be pressed in, the burner sucking in the air necessary for perfect
combustion.
In order to make my invention more easily understood, I have illustrated it on the
accompanying drawing, which shows a sectional elevation of my improved burner.
a is the feed pipe for the liquid, gaseous or pulverized fuel. 6 is the air introduction
pipe.
The fuel feed pipe a runs out into a nozzle d, the opening of which can be closed
more or less according to the amount of fuel to pass out of it, by the cylindrical
rod m being raised or lowered within the said pipe a and nozzle d. The nozzle a is
surrounded by a hollow, somewhat coneshaped casing or mantle c and this latter
again is surrounded by the mantle n. Between the nozzle and the mantle cand
between this latter and the outer mantle n annular spaces and g respectively are
formed, through which the air entering through pipe b can freely pass. The casing
or mantle c runs out into a bulb-shaped casing k, being provided with a number of
elongated slots f. The annular space i formed between this casing and the outer
wall p of the apparatus stands in connection with the annular space g. At the con-
stricted portion of the mantle c a short piece of pipe h is provided, giving access
from without to the interior of the igniting chamber e. For starting ignition the
flame of a soldering lamp or a gas blast is introduced through the pipe h into the
chamber e with the effect of heating the burner and setting up ignition. After
the burner is heated to the desired degree, the lamp or gas flame is removed and the
pipe h is to be plugged up. The burner will now steadily keep up ignition on its
own accord. If liquid or pulverized fuel is made use of, pressure air must be intro-
duced through pipe b. Part of the air entering through pipe b may take its course
through the annular space g in order to attain the highest temperature in the annular
space i and not within the chamber e. A column of flame will be projected out of
the opening into the compartment not containing or having at least no direct
communication with the atmosphere.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is
The general arrangement, construction and combination of the various parts for

the igniting chamber, igniting the mixture therein and projecting a column of flame
out of a slotted bulb-shaped casing, substantially as described and shown by the
accompanying drawing.
