PROVISIONAL SPECIFICATION.
Improvements in Extinguishing Apparatus for Oil Burners.
1, OTTO WOLLENBERG, of 11 Luckauer Strasse, Berlin in the Empire of
Germany do hereby declare the nature of this invention to be as follows:-
This invention for improvements in extinguishing apparatus for oil burners consists
of an extinguishing sleeve adapted to slide on the outside of the burner tube and of an
operating sleeve mounted on the operating spindle of the wick raising and lowering
device and suitably connected to the extinguishing sleeve so that on actuating the
operating sleeve from outside the lamp the extinguishing sleeve is raised against
the spreader to extinguish the lamp. The mechanism connecting the operating
and extinguishing sleeves consists of a toothed sector on the operating sleeve, a
rack gearing in the sector and guided within the tube and of a cross arm connecting
the rack with the extinguishing sleeve and passing through an opening in the
burner tube. The sector and rack may be replaced by a slotted bracket and a rod
with pin engaging in the groove.

Improvements in Extinguishing Apparatus for Oil Burners.
I OTTO WOLLENBERG, 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 for improvements in extinguishing apparatus for oil burners
consists of an extinguishing sleeve adapted to slide on the outside of the burner
tube and of an operating sleeve mounted on the operating spindle of the wick
raising and lowering device and suitably connected to the extinguishing sleeve so that
on actuating the operating sleeve from outside the lamp the extinguishing sleeve is
raised against the spreader to extinguish the lamp. The mechanism connecting the
operating and extinguishing sleeves consists of a toothed sector on the operating
sleeve, a rack gearing in the sector and guided within the tube and of a cross arm
connecting the rack with the extinguishing sleeve and passing through an opening
in the burner tube. The sector and rack may be replaced by a slotted bracket and
a rod with pin engaging in the groove.
In the accompanying sheet of illustrative drawings:
Figs. 1 and 2 are vertical sections through a petroleum burner fitted with the
extinguishing apparatus showing the extinguishing sleeve in its two positions and
Fig. 3 is a part vertical section at right angles to Figs. 1 and 2 showing the
extinguisher mechanism in side elevation, and
Fig. 4 is an inverted plan of Fig. 2.
On the operating spindle a of the wick raising and lowering device is loosely

page_text: mounted, so that it can be independently rotated, the sleeve provided with the
operating lever c and with the toothed sector d engaging in the guided rack e
connected by the cross arm e¹ with the guide rod sliding on the inside of the
inner burner tube and connected by the cross piece with the extinguishing
sleeve which slides on the outer burner tube i. The crosspiece h¹ passes through
the slot k which is arranged in the usual manner through the two burner tubes g
and for the inlet of air to the interior of the burner. On one side of the
opening is formed the guide for the connecting piece ' since it slides up and
down thereon. Here also is fixed the slide keeping the rod f straight. The
spreader m is connected by a bayonet joint to the inner burner tube g or on a
central rod n so that it is not variable in height.
If the flame is to be extinguished the lever arm c is pressed out of the position
shown in Fig. 1 into the position of Fig. 2 which can be done directly by hand or
by means of a small chain o. The sleeve and the sector d is thereby rotated and
by means of the rack e, the sliding rod f and the extinguisher sleeve / are moved
upwards until the sleeve touches the spreader thereby cutting off the air and
extinguishing the flame. By raising the lever arm c the raised parts are again
brought to their original positions.
In place of the lever e a milled head b' can be fitted on the sleeve b the
same as a¹ is fitted on a. In Figs. 1 and 2 this modification is shown by dotted
lines.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :
Extinguishing apparatus for cil burners consisting of the hollow sleeve mounted
loosely over the wick raising spindle, of mechanism fitted within the inner burner
tube and connecting the extinguishing sleeve to the hollow sleeve so that by
actuating the hollow sleeve the extinguishing sleeve can be raised or lowered.
