Improvements in Extinguishing Apparatus for Petroleum Burners.
IT
I MAX KRAY, Lamp Manufacturer of 7 Boeckstrasse, 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 petroleum burners
has for its object to provide an apparatus which is to a certain extent double acting
and certain in action. The extinction of the flame takes place first by the screwing
down of the wick into the wick tube and furthermore by preventing access of air
by means of an extinguishing sleeve which slides on the outer burner tube and for
the purpose of extinction can be raised up to or above the outer edge of the
deflector. The movement of the wick and the extinguishing sleeve takes place
simultaneously by means of the wick raiser in such manner that if the wick is
turned up the extinguishing sleeve is lowered and on the contrary if the wick is
turned down the extinguishing sleeve is raised.
On the accompanying drawing a petroleum lamp is shown fitted with this
extinguishing apparatus.
Fig. 1 is a vertical section through the lamp.
Fig. 2 is a side view of the burner and of the extinguisher gear with the wick
sleeve raised and with extinguisher sleeve lowered.
Fig. 3 is a side view of the burner and the extinguisher gear but with lowered
wick tube and raised extinguisher sleeve.
Fig. 4 is a horizontal section through the line x-x of Fig. 2.
The wick a is inserted in the usual manner between the burner tubes b and c by
means of a sleeve d which engages in the wick by means of spikes e. To the
lower end of the wick guide sleeve d is fastened by means of a short cross piece,
the lower end of the toothed gear rod finto which engages the small gear wheel g
on the wick raiser h. On the other side the gear wheel also engages in a second
toothed rod i which is fastened at its top end to the extinguisher sleeve k. The
latter slides on the outer burner tube c and a parallel motion is imparted thereto by
a rod a sliding in a guide tube on the gear case. The toothed rods fand i in the
gear case are also constrained to give a parallel motion.
Above the burner is arranged the disc or flame spreader o.
If the wick raiser is turned to the right the toothed rod fis elevated and
the toothed rod i is lowered. Consequently the wick a projects above the burner
tubes b and c whilst the extinguisher sleeve k falls until it is below the upper edges
of these burner tubes. In this position the lamp can be lit for use and the flame
regulated as required by means of the finger disc h¹.
If the wick raiser h is turned to the left the toothed rod f falls whilst the toothed
rod i rises. Consequently the wick retreats between the burner tubes b and c
whilst the extinguisher sleeve k is pushed up to the lower surface of the flame
spreader o or upwards above its outer edge (Fig. 3). In this position the flame is
at once extinguished entirely without smell.
Hitherto in order to produce the double action above mentioned it has been
necessary first to screw down the wick by means of the wick spindle and then
raise the extinguishing sleeve by means of a second spindle. In this invention this
double action takes place in one operation of the wick spindle. A special spindle
or lever for the extinguisher sleeve not being necessary the construction of the
lamp is greatly simplified.

page_text: For hanging lamps a chain can be attached to the finger disc of the wick
spindle by means of which the regulation and extinction of the flame can be effected
from underneath.
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 I
claim is :
1. A double acting extinguishing apparatus for petroleum burners in which the
wick guide sleeve and an extinguisher sleeve, sliding on the burner tube.up to or
over the flame spreader, are connected with the wick spindle in such manner that
by rotation of the wick spindle in one or the other direction simultaneous lowering
of the wick and raising of the extinguisher sleeve, or vice versa raising of the wick
and lowering of the extinguisher sleeve, are effected.
