Improvements in or relating to Incandescent Lamps.
I, BELA FRIED of Budapest in the Empire of Austria, Manufacturer, do
hereby declare the nature of this invention and the manner in which the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
The present invention has for object the adaptation of the intense, white but
agreeable light burned by the Auer lamps (which, however, can only be used in
connection with gas lamps) to household purposes or in places where there are no
gas mains, its main feature consisting in the generation of gas in a cistern, in just
sufficient quantity for the intensity of the light required, and which gas generation
is continued during the whole time the lamp is burning.
I will describe my invention with reference to the accompanying drawings in
which:
Figure 1 is a view of the lamp.
Figure 2 is a sectional elevation and
Figure 3 shows the star-shaped tubing and indicator.
In the inside of the lamp is a cistern a in which a star-shaped tube b is placed,
the under end of said tube being open, while the ends of its other branches or arms
are closed hermetically. In the space underneath the cistern, a spirit lamp c is
placed, the flame being regulated in such way by the adjuster d projecting outside
the casing of the lamp, that, when the indicator points upwards, the flame is at
full, whereas, when said indicator points downwards, the intensity of the flame is
only very slight.
By means of an aperture which also serves as safety valve, spirits, ligroine,
benzine or other liquids, are poured into the cistern a and there heated, thus
generating the combustible gases required.
The spirit burner is ignited and kept burning with full flame for a few minutes
before the lamp is required for use for the purpose of generating the necessary
quantity of gas. The generation of the combustible gas is very much accelerated
by the branches of the star-shaped tube in the cistern, since the heating surface is
by this means considerably increased. The developed gas passes out through the
aperture e of the lamp, and changes the Auer gauze or tissue into an incandescent
state, a very fine and agreeable light being thereby obtained.
There is absolutely no danger connected with the lamp, since the gas is burned
as it is developed, it being merely necessary to reduce the intensity of the flame of
the spirit lamp by means of the adjuster d in case the generation of gas be stronger
than is required.
The lamp can be ignited automatically by means of a burner ƒ fastened on a
telescopic tube or stand g and which can be set at any height desired.
Having now particularly described and ascertained the nature of my said inven-
tion and the manner in which the same is to be performed, I declare that what I
claim is:
A lamp in which the Auer gauze or tissue is heated into an incandescent state
by combustible gases generated in a cistern a by same being filled with spirits, ligroine,
and

substantially as described and shown in the accompanying drawing.
Dated this 22nd day of December 1892.
