We, ARTHUR CAUTIUS and CARL PATAKY, both of Berlin, in the Empire of
Germany, do hereby declare the nature of this invention to be as follows:-
Our invention relates to an improved burner for petroleum and other lamps.
The improved burner is provided with a hollow wick, and is distinguished especially
by its simplicity. The improved burner can be provided with a circular wick adapted
to burn either on the internal or the external surface, or it can be provided with a
wick to burn with a flat flame.
We will first describe simultaneously the two modifications wherein the flame is
adapted to burn upon the inner and outer sides of the wick respectively.
To the oil receptacle at its lower end is attached an upwardly projecting tube herein-
after termed the inner tube and at the upper end are formed screw threads into which
is screwed a second tube hereinafter termed the outer tube. Between these two tubes
is placed the round lamp wick, which can be held by springs or pointed hooks on the
first tube in order to secure it against unintentional displacement.
The upward movement of the wick is limited by a cap arranged upon the outer
tube according to the first modification.
In the second modification however, it is inserted into the inner tube. In the first
modification the inner tube is below the level of the top of the wick, so that between
the cap and the upper edge of the inner tube is formed a cylindrical burning surface
the breadth of which is determined by the distance. In the second modification an
external burning surface is provided owing to the outer tube being below the end of
the wick.
By this arrangement a considerably larger burning surface of the wick is produced
and consequently a much greater development of light than was possible in round-
burners of equal diameter as heretofore used.
In the inner tube of the burner constructed according to the first modification is
arranged a third tube fitting closely within the said inner tube. This third tube herein-
after termed the adjustable tube protrudes below the inner tube and is here provided
at its lower end with a flange. Near its upper end it carries, in a socket held by three
ribs, the stem of a deflector disc.

page_text: This displacement of the adjustable tube is effected by means of an inclined slot in
the outer tube and of a pin on the inner tube projecting into the said slot so that on
turning the adjustable tube by the lower flange an upward and downward motion of
the said tube takes place.
The adjustable tube can be raised sufficiently to cover the burning surface of the
wick.
According to the second modification the adjustable tube surrounds the outer tube.
This adjustable tube can likewise be displaced in the direction of its length by pins
fixed to the same being displaced in inclined slits. In the highest position of the
adjustable tube the burning surface of the wick is also here closed towards the outside.
The remaining arrangements of the burner do not essentially differ from other
burners.
It is to be understood that the construction hereinbefore described is susceptible of
numerous modifications.
The improved burner is distinguished from other burners by very great wick burning
surfaces, therefore by great light-giving capacity, while the diameter of the burner is
comparatively small; by the extraordinary simplicity of construction, no screws, racks,
toothed wheels or the like being employed for moving the wick; the regulation of the
light is effected by simply turning the adjustable tube and the extinction of the lamp
can be effected instantaneously; any danger of explosion, or a generation of bad
smelling gases and the like is obviated and the entire space occupied by the oil is
closed air and gas tight.
The burner tube may also be made flat instead of round. From the above
description however the construction of this burner having an internal burning surface
will be readily understood. The lower portion of the inner tube is cylindrical and is
attached to the oil receptacle but has a flat form at its upper end. The adjustable tube,
the outer tube and the cap are flat also.
This displacement of the adjustable tube can be effected in various manners. For
instance from the lower end of the inner tube can extend a rod having screw threads
fitting into a corresponding nut or socket. If the nut or socket, which is supported in
a suitable manner is caused to turn by means of a handle the slide is displaced and the
burning surface is increased diminished or altogether covered.
The Hat burner may have an external burning surface by slightly modifying the
construction in a manner easily understood from the foregoing description.

page_text: We, ARTHUR CAUTIUS, and CARL PATAKY, both of Berlin, in the Empire of
Germany 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 follow-
ing statement:-
Our invention relates to an improved burner for petroleum and other lamps.
The improved burner is provided with a hollow wick, and is distinguished especially
by its simplicity.
The accompanying drawings illustrate various forms of our invention.
The improved burner can be provided with a circular wick adapted to burn either
on the internal surface as shewn in figure 1 or on the external surface figure 2 or it
can be provided with a wick to burn with a flat flame figure 3.
Figure 1 and 2ª shew cross sections on the line x and y y and figure 1' the
position of the various parts of the burner when closed.
We will first describe simultaneously the two modifications wherein the flame is
adapted to burn upon the inner and outer sides of the wick respectively.
To the lower end of the oil receptacle, figures 1 and 2 is attached an upwardly
projecting tube 6 hereinafter termed the inner tube and at the upper end are formed
screw threads into which is screwed a second tube c hereinafter termed the outer tube.
Between these two tubes b and c is placed the round lamp wick d which can be held
by springs or pointed hooks e on the tube b in order to secure it against unintentional
displacement.
The upward movement of the wick d, is limited by a cap farranged upon the outer
tube c in the burner figure 1.
In the modification shewn in figure 2, however it is inserted into the inner tube b.
In figure 1 the inner tube b, is below the level of the top of the wick, d, so that between
the cap and the upper edge of the inner tube b is formed an internal cylindrical
burning surface g the breadth of which is determined by the distance between f and b.
In figure 2 an external burning surface g' is provided owing to the outer tube being
below the end of the wick d.
By this arrangement a considerably larger burning surface of the wick is produced
and consequently, a much greater development of light than was possible in round
burners of equal diameter heretofore used.

page_text: In the inner tube 6 of the burner constructed according to the first modification
shown a third tube is arranged fitting closely within the said inner tube. This third
tube protrudes below the inner tube b and is here provided at its lower end with a
flange ², near its upper end it carries, in a socket k held by three ribs the stem of
a deflector disc m.
The displacement of the adjustable tube h in b is effected by means of an inclined
slot in the outer tube band of a pin o on the inner tube projecting into the said
slot so that on turning the adjustable tube by the lower flange h³ an upward and
downward motion of the said tube 7 in b takes place. In figure 1, is shown in its
lowest position, leaving the space between the cap fand the upper edge of b, that is to
say the internal burning surface of the wick. The adjustable tube can be raised
sufficiently to cover the burning surface of the wick, and also cause the burner opening
to be closed air and gas tight.
This
According to the second modification shown in figure 2 the adjustable tube / is here
placed on the outside, and this tube therefore surrounds the outer tube c.
adjustable tube h¹ can likewise be displaced in the direction of its length by pins p p
fixed to the same being displaced in inclined slits in the lamp basket q. In the highest
position of the adjustable tube h¹ the burning surface of the wick is also here closed
towards the outside.
The remaining arrangements of the burner do not essentially differ from other
burners.
It is to be understood that the construction hereinbefore described is susceptible of
numerous modifications.
The improved burners shown in figures 1 and 2 are distinguished from other burners
by very large wick burning surfaces, and therefore by great light giving capacity,
while the diameter of the burner is comparatively small; by the extraordinary
simplicity of construction, no screws, racks, toothed wheels or the like being employed
for moving the wick; the regulation of the light is effected by simply turning the
adjustable tube h or h¹ and the extinction of the lamp can be effected instantaneously:
any danger of explosion, or generation of bad smelling gases and the like is obviated
and the entire space occupied by the oil is closed air and gas tight.
The burner tube may also be made flat instead of round. A modification of figure 1
for this purpose is represented in figure 3, whilst figure 3ª represents a plan view of
the burner opening.
From the above description the construction of this burner having an internal
burning surface will be readily understood. The lower portion 62 of the inner tube b
is cylindrical and is attached to the oil receptacle a but assumes a flat form at its
upper end. The adjustable tube 2 the outer tube and the cap f* are flat also.
The displacement of the adjustable tube 2 can be effected in various manners for
instance, from the lower end of the inner tube can extend a rod r having screw
threads fitting into corresponding nut or socket. If the nut or socket, which is
supported in a suitable manner is caused to turn by means of a handle t, the slide is
displaced and the burning surface g³ is increased, diminished or altogether covered:
The flat burner may have an external burning surface by slightly modifying the
construction in a manner easily understood from the foregoing description.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is ;
cap
First. A burner in which the wick d is enclosed between the inner tube b the outer
tube c and the cap f covering the upper surface of the wick, so that an internal wick
burning surface g is created by the inner tube b terminating below the
thus being
shorter than the outer tube, as described and shewn in figures 1, 1° and 15.
Second. A burner in which the wick is enclosed between the inner tube b and the
cap so that an external wick burning surface g¹ is created by the outer tube c
terminating below the cap, thus being shorter than the inner tube as described and
represented in figures 2 and 2",

page_text: Third. A burner having a flat wick and an internal wick burning surface g³, as
described with reference to figure 1; with the difference that the inner tube b× the outer
tube and the cap f' are not round but flat, as described and represented in
figures 3 and 3º.
Fourth. In the burner represented in figure 1 an inner tube h which can be caused
to slide in the tube b for the purpose of diminishing, increasing or entirely closing the
burning surface g, as described and shewn.
Fifth. In the burner represented in figure 2 an outer tube h¹ which can be slid upon
the outer tube c for the purpose of diminishing, increasing, or entirely closing the
burning surface g¹ as described and shewn.
Sixth. In the burner represented in figure 3 an inner flat tube
which can be slid
in the upper flat part of the inner tube 6 for the purpose of diminishing, increasing
or entirely closing the burning surface as described and represented.
