PROVISIONAL SPECIFICATION.
An Improved Vaporizing Burner for Oil.
We, JOHN BARANY of 14 Friedrichstrasse and JOSEPH MÜCKE of 12-
Holzmarketstrasse, both of Berlin, in the Empire of Germany, Manufacturers,.
do hereby declare the nature of this invention to be as follows:-
Our present invention consists of a burner for gasifying oils and for consuming
the gas thus produced, the said gas either being burnt as illuminating gas or used
in a Bunsen or other burner to produce an incandescent light.
It is well known that some parts of oil gasify at about 70° C., whilst other
constituent parts of the same oil will not gasify under 150° C. This fact renders.
it necessary to gasify oil at a temperature of at least 150° C. if it is required to.
gasify all the oil, which is desirable.
According to the present invention the oil to be gasified is conducted into an
inverted bell having its mouth sealed by suitable metal, such metal being confined
in a chamber communicating with the burner. If heat is now applied to the
chamber the metal will be melted, and the heat which causes the metal to melt will
gasify the oil in the bell above the metal. This gas will depress the molten metal
inside the bell, escape into the chamber in which the metal is confined and pass to
the burner. On turning off the oil supply the molten metal will again seal the bell
and harden, when the heat is removed, thus sealing the mouth of the bell and
preventing the escape of vapours.
By choosing a metal mass which will not melt under a temperature sufficient to
completely gasify all the oil, a very regular and sufficient supply of oil gas to the.
burner will be obtained.

An Improved Vaporizing Burner for Oil.
We, JOHN BARANY of 14 Friedrichstrasse and JOSEPH MÜCKE of 12-
Holzmarktstrasse, both of Berlin, in the Empire of Germany, Manufacturers,
do hereby declare the nature of our 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 constituent parts of fluid fuels do not all gasify at the
same temperature and this fact renders it difficult to attain complete gasification in
connection with oil gas burners, which is necessary in order to cause the mantle of
Thus for instance ordinary
an incandescent gas burner to glow evenly all over.
paraffin contains constituents which gasify below 100° C., whilst other of its.
constituents will not gasify until the temperature has reached 150° C. One of
the objects of the present invention is to keep the temperature at such point that
all the constituent parts of the liquid fuel shall be gasified and only dry gas be
consumed by the flame.

page_text: And in order to render the present Specification, more easily intelligible reference
is had to the accompanying drawing in which similar letters of reference denote
similar parts throughout the several views:
Fig. 1 being a vertical section through the complete burner,
Fig. 2 a cross section on line A-B of Figure i and
Fig. 3 a similar section on line C-D of Figure 1.
The main feature of the apparatus comprises the fusible metal mass a in the
chamber b which encircles the end of the pipe c through which the supply of fluid
is taken, said pipe end extending into the chamber b a short distance. Over the
end of the pipe c is arranged in the chamber b a bell e, the open end of which
extends down into the fusible mass. Below the chamber a is arranged a chamber i
having vertical wicks extending into it from above said wicks being arranged
underneath the chamber b. The fluid fuel is fed to the chamber i by means of
pipe which leads through the pipe c. In the passage leading from the chamber b
to the burner a valve fis arranged, the stem of which is tightly attached to a
membrane gas is usual in valves of this kind, so as to prevent the escape of gas.
By means of the valve f the gas feed to the burner may be regulated in the well
known manner.
The device operates in the following manner :-
The chamber i is arranged a little distance from the tube c in order to prevent
heating the former. The jets i¹ are ignited, whereby the metal in the chamber bis
melted, allowing the bell free play. The fuel under pressure enters the bell e and
is there gasified and forced through the fusible metal a to the burner, as soon as
the valve is opened. On closing the valve f and extinguishing the jets i¹ a part
of the molten metal will pass back under the bell e and will there slowly harden,
forming a safe closure to prevent the escape of any gas which may remain in the
pipe c.
Having now particularly described and ascertained the nature of our inven-
tion and the manner in which the same is performed, we declare that what we
claim is :-
1. A process for gaining dry gas for illuminating, heating and other purposes,
which consists in forcing the liquid fuel supplied from a reservoir through an
interposed molten metal mass, substantially as described.
2. A gas burner having a feed pipe c extending into a chamber b containing a
fusible metal mass and a bell arranged over the end of the said feed pipe in Baid
chamber substantially as described and for the purpose specified.
