I LEO KUMBERG of Kammshrostrow Prospect, Hans 1/7 in the City of St. Peters-
burg in the Russian Empire, Merchant, do hereby declare the nature of my
Invention for "IMPROVEMENTS IN LAMPS FOR BURNING HYDRO CARBONS
and in
what manner.
the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to an improved system of pneumatic hydro carbon illumi-
nating or lighting in which petroleum or bydro carbon or oils of heavy specific
gravity can be employed as illuminating material in lamps without cylinder or
chimney, without smoke or soot formation and with gas like flame. Hitherto in
constructions of this kind mechanical power was requisite in order to produce the
necessary draught for instance in the one case a clock like mechanism, for driving
a ventilator, in another case an air blower driven by steam power. In employing
my construction the requisite current of air is generated by a lamp or other source
of warmth arranged in a receptacle so that suction is exercised on the air and so
that any desired number of lamps connected with the said receptacle by pipes or
tubes can be fed consequently neither steam engine or clock work is necessary.
This system of lighting can be employed anywhere without being limited in the
application to the presence of steam power.
My illuminating system is further free from the stoppages and disturbances often
caused by the clockwork or other mechanism.
The current of air generated according to my invention is preferably equable
which can be attained by no other system so that the flame of the lamp will burn
steadily without flaring and without requiring special regulating valves.
The costs of fitting up this kind of lighting are very small in comparison with
other systems and the parts used are so simple that repairs are almost entirely
avoided.
Figure 1 is a part elevation of my improved illuminating or lighting system.
Figure 2 is a top view,
Figure 3 a section through one of the lamps in natural size,
Figure 4 is a vertical section of the ventilator.
The pipes or tubes a b c leading to the three stories of a house, factory or other
building, are connected at their lower ends to the ventilator A which rests on the
feet ee
The pipe or tube c leads to the first floor, b to the second and a to the

page_text: In order to attain a like current a pressure of air in all three stories, the pipes
or tubes are of different diameter so that o is larger than 6 and 6 larger than a.
In order to produce a continuously equable pressure or current of air an ordinary
lamp or or other suitable smokeless heating apparatus is placed in the ventilator
which rarefies the air in the same, causes the atmospheric air to enter the said
ventilator at g h and to flow in the direction represented by the arrows into the
pipes or tubes a b c.
The air ascends in the said pipes or tubes abc in such manner that a current of
air is supplied equably to the different stories by means of the pipes or tubes fff
to which the lamps are attached.
The air supplied to the pipes or tubes f flows through the opening n into the
spaces between the hydro-carbon reservoir p and the outer casing o which are
made in the form of two concentrical spheres or in other appropriate form of which
as aforesaid p forms the reservoir, o the outer casing and passes up through g
around the wick when the consumption of the hydro-carbon ensues the layer of air
surrounding the flame preventing all flaring of the same.
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:-
A hydro carbon illuminating or lighting system characterised by:-The combina-
tion of the ventilator A and a lamp or other warmth producing apparatus in the
interior of the said ventilator with the pipes or tubes a b c and f and the air
spaces between the walls op so that atmospheric air is drawn in by the said
ventilator and fed to and around the flame of the lamp by passing through the
aforesaid pipes a b c f, outlet n, air space s and outlet q substantially as described
and shown.
