An Improved Circular Petroleum Burner with Detachable Wick
Carrier.
I, OTTO WOLLENBERG, Metal Goods Manufacturer, of 11 Luckauerstrasse,
Berlin, in the Empire of. Germany, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in such petroleum circular burners as
are made with the wick carrier cylinders detachable from the burner so as to
permit a more easy and convenient. insertion of the wick. In order to prevent
an automatic fall downwards, the wick tube is connected to the burner by a
spring arrangement releasing outwards. This apparatus can be constructed
in two ways.
In one way the toothed rod of the wick raising apparatus is
fixed to the wick carrier cylinder and the latter is detachably connected by.
means of clip springs to the lower ends of the inner wick carrier tube, in this
case the wick carrier together with the toothed rod can be withdrawn from the
burner after releasing the clip spring. In the other way the toothed rod is firmly
attached, though adjustably, to the burner, and the wick carrier is detachably
connected to the toothed rod. In this case, only the wick carrier can be detached
from the burner.
In the first named arrangement the lower end of the toothed rod and the bottom
plate of the wick carrier are firmly attached. The carrier is open on one side
throughout its entire length and is provided at the top with 'two indentations.
The lower end of the inner wick tube has a part cut away through which project
the ends of a flat spring. which is attached to it. The toothed rod is actuated by a
pinion and slides up and down in a guide cylinder. The wick carrier engages by
means of cogs or spikes in the wick and is prevented from falling out of the
burner, at its lowest position, by the engagement of the beforementioned spring
ends and indentations.
In the second arrangement the toothed rod, not detachable from the burner,
carries at the lower end a small disc with extending lower part and projecting
edge, whilst the wick carrier cylinder is provided at the lower part with an inner
edge and a band spring engaging over its vertical slot. A bent up tongue of the
cylinder rim serves as a stop when releasing the said spring. At the upper part
the said cylinder loosely surrounds the inner wick tube.

An Improved Circular Petroleum Burner with Detachable Wick
Carrier.
I OTTO WOLLENBERG, Metal Goods Manufacturer, of 11 Luckauerstrasse,.
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 following statement :-
This invention relates to improvements in such petroleum circular burners as are
made with the wick carrier cylinder detachable from the burner so as to permit a
more easy and convenient insertion of the wick. In order to prevent an automatic
fall downwards, the wick tube is connected to the burner by a spring arrangement
releasing outwards. This apparatus can be constructed in two ways.
In one way
the toothed rod of the wick raising apparatus is fixed to the wick carrier cylinder
and the latter is detachably connected by means of clip springs to the lower ends
of the inner wick carrier tube in this case the wick carrier, together with the
toothed rod, can be withdrawn from the burner after releasing the clip spring. In
the other way, the toothed rod is firmly attached, though adjustably to the burner
and the wick carrier is detachably connected to the toothed rod.
In this case,
only the wick carrier can be detached from the burner.
In the accompanying sheet of illustrative drawings, Figs. 1-3 refer to the first,
and Figs. 4-6 to the second of these methods of construction. Figs. 1 and 2 are
vertical sections through the complete burner and also horizontal section on the
line of Fig. 2, Fig. 1 showing the wick burner quite down, and Fig. 2 as
turned up to the height for burning. In Fig. 3 the wick carrier together with the
attached toothed rod is shown in detail. Fig. 4 shows vertical and horizontal
sections through the lower part of a burner constructed according to the second
method of construction, and Figs. 5 and 6 show the lower part of the burner
separated from the wick carrier in elevation and plan.
In the arrangement illustrated in Figs. 1-3 the lower end of the toothed rod a
and the bottom plate of the wick carrier bare firmly attached. The carrier bis
open on one side throughout its entire length and is provided at the top with two
indentations c. The lower end of the inner wick tube d has a part e cut away
through which project the ends ff, of a flat spring f which is attached to it at d².
The toothed rod a is actuated by a pinion g and slides up and down in the guide
sleeve. The wick carrier bengages by means of teeth or projections i in the
wick and is prevented from falling out of the burner at its lowest position
(Fig. 1) by the engagement of the beforementioned spring ends f, f¹ and
indentations c.
If a new wick is to be inserted or an old wick is to be raised after the top
portion has burnt away the said toothed rod wick and wick carrier are turned
right down, the said spring ends f, f¹ are then pressed together until the indented
parts c, c are released when the parts a bk can be drawn off downwards. By this
operation the wick carrier is left quite free so that the wick can now be pushed in
upwards from below with greater facility. The wick carrier bis then pushed up
over the inner tube d until the spring ends f¹¹ snap into the indentations c c.
By turning the wick spindle the toothed rod a wick carrier b and wick k can now
- be raised the spring ends ff being caused to slide along the edges 61 61 of the
opening of the wick carrier o into the compressed position Fig. 2.

In the second arrangement illustrated in Figs. 4-6 the toothed rod a not
detachable from the burner carries at the lower end a small disc m with extending
lower part m and projecting edge m² whilst the wick carrier cylinder b is provided
at the lower part with an inner edge n and a band spring f engaging over its
vertical slot. A bent up tongue n¹ of the cylinder rim n serves as a stop when

page_text: releasing the said spring f. At the upper part the said cylinder
surrounds the inner wick tube d.
loosely
If a new wick is to be drawn in or an old wick is to be raised then the parts ab k
are as before first turned quite down and the spring of slightly raised with the
finger so as to bring it in front of the lip n¹. The cylinder 6 can now be drawn
down and the wick k be pushed in between the tubes thereby exposed. The
cylinder b is then pushed up from below over the wick tube d until the edge m³ of
the disc m snaps between the spring f and the cylinder rim n. On turning the
wick raising pinion g the toothed rod a and wick cylinder bare raised upwards, the
wick & becoming engaged by the spikes i of the cylinder band moved therewith.
The method of connection described is marked in both cases by the advantages
of great simplicity, easy and convenient handling and reliable action as compared
with similar arrangements.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what
claim is:
In circular petroleum burners, the wick carrier cylinders of which, for the
purpose of easily inserting the wick can be detached from the burner :-
1. The detachable connection of the wick carrier cylinder 6 with the lower end
of the inner wick tube d by means of a spring ƒ and indentations c in the cylinder
whereby the toothed rod a of the wick motion g is firmly attached to the cylinder b
and can be detached therewith.
2. The detachable connection of the wick carrier cylinder with the lower end of
the toothed rod a by means of a spring f on the cylinder 6 and a projecting rim m²
on the toothed rod a whereby the latter cannot be removed therewith from the
burner.
