Improvements in Oil Lamps.
I, JOEL SANDER, of 20, Admiralitätstrasse, Hamburg, Germany, Constructor,
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 an arrangement which is particularly suitable for
petroleum lamps and which has for object to prevent, in a most simple manner,
all danger of explosion or fire in case of the lamp falling or tipping over.
A petroleum lamp provided with this arrangement is illustrated in section in
the accompanying drawing; it comprises the lamp proper a, an oil holder b, a
float vessel e and a cover d. The oil vessel b is so constructed that it will float with
the greatest possible stability in a liquid, whilst it is also adapted when outside of
the float vessel to stand firmly upright on any straight surface.
The neck b of the oil vessel is fixed in the usual manner in a ring f serving for
the reception of the burner and its accessories. For greater convenience in
handling the float vessel c is made in the form of a goblet-like vessel, the hollow
foot of which serves to still further increase the capacity of the vessel. The
cover d is either loosely mounted on the vessel c being secured from falling by
means of its edge d, or it may be fixed in any suitable manner.
The float vessel c is usually filled with clean water in which the oil holder b
floats. Too great a depth of immersion (which might take place when the upward
buoyancy was too small by reason of the oil holder being freshly filled) is pre-
vented by the edge fl of the ring f which is mounted on the edge of the aperture
of the cover, which then holds the lamp suspended.
The oil holder b float vessel c and cover id are preferably made of white glass
so that, in combination with the clean water an increased illuminating effect is
produced in a downward direction and the formation of shadows is prevented.
The said parts may of course be made of any other transparent or non-trans-
parent material, whilst also instead of the float vessel being filled with water it
may be filled with any other suitable liquid adapted to extinguish flame. The
d may sometimes be dispensed with.
cover
If the burning lamp should fall or be tipped over, the water flows out of the
float vessel, and extinguishes the flame at once, so that all fire or explosion is
nipped in the bud.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A non-explosive lamp comprising an open float vessel c (which may or may not
be provided with a cover d) in which the oil holder 6 floats, the arrangement being
such that the water or other suitable liquid in the float vessel will flow out and
extinguish the flame in the case of the lamp falling or being tipped over, substan-
tially as described.
2. In a lamp such as specified in Claim 1, an edge or border support f¹ which,

page_text: in combination with a cover d prevents the too great immersion of the oil holder b,
substantially as described.
3. My improved lamp constructed and operating as shewn in and described with
reference to the drawing.
Dated this 9th day of September 1898.
