PROVISIONAL SPECIFICATION.
Improvements in Gas Burners.
I, JOSEF HELLMANN, of Vienna, 1II Apostelgasse, 34, in the Empire of Austria,
Gentleman, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in gas burners and is more especially appli-
cable to burners adapted for heating purposes, but it may be applied to the lighting
burners of incandescent gas lamps. The object of the invention is to increase the
production of heat and at the same time diminish the consumption of gas.
From
According to my invention the gas and air are supplied through two concentric
tubes from which they flow into radial directions into an annular chamber.
this chamber the mixture ascends vertically through suitable channels in the burner
and is burned upon the top thereof producing an annular flame.
In carrying my invention into effect I provide a suitable gas supply tube around
which 1 arrange an air supply tube. Provision is made for the delivery of the air up
through the body of the burner in an annular form within the gas flame.
1 provide a circular perforated diaphragm upon the top of the burner for the
purpose of preventing the flame being drawn thereinto.
A suitable device is provided for supporting the incandescent body.
The air supply above described may be dispensed with, but then the closure of the
flame upon itself is prevented by forming a central cavity in the burner top, or a
metal disc may be used instead of the cavity.
The burner above described is applicable to and under any circumstance where an
efficient and economica! burner irrespective of the material of which it is made, is
required for lighting or heating purposes.
Dated this 15th day of November 1888.

COMPLETE SPECIFICATION.
Improvements in Gas Burners.
I, JOSEF HELLMANN, of Vienna, Apostelgasse No. 34, in the Empire of Austria,
Gentleman, 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 present invention refers to improvements in round gas burners, more par-
ticularly to those intended for heating purposes; but it may also be employed in
incandescent gas lamps for lighting purposes.
The object of the invention is to increase the heating power, and to reduce the
consumption of gas.
In the accompanying drawings,
Fig. 1 is a vertical section through an improved burner.
Fig. 2 is a horizontal section of Fig. 1, on the line through the two concentric
air and gas tubes.
Fig. 3 is a similar section on the line y―y.
Fig. 4 represents a modification of a smaller burner with a free discharge opening
for the gas, as the tube is open at its top.
Fig. 5 represents another modification, similar to Fig. 4, but with a fan-like or
radiated discharge of the gas.
Referring to Fig. 1. a notable feature of my invention consists in the extension of
the tube a (supplying a mixture of gas and air) over the top of the round-burner, in
Price 6d.
