Regenerative Hydro-carbon Lamp or Lantern with Special Outlet
for the Products of Combustion.
We, LASSLO CHANDOR of 60 Gorochowo, in the City of St. Petersburg, in the
Empire of Russia, Gentleman, and CARL HEINRICH NÖLTING of Dunster House, Mark
Lane, London, E.C. Merchant, do hereby declare the nature of our said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Our invention relates to a regenerative hydro-carbon lamp or lantern in which no
glass chimney is employed and in which the requisite air for feeding the flame is led
to the same from below in a highly heated state, whereas the products of combustion
are led off by a special tube which is so heated by the said products of combustion
passing through the same, that the aforementioned tube serves to heat the air fed to
the flaine.
.
By means of this device and in consequence of the brisk and regular leading off
of the products of combustion and in spite of no glass chimney being employed, a
perfectly steady, bright flame is produced which, consequent on the perfect
consumption of the hydro-carbon employed, is almost pure white.
All kinds of hydro-carbon can be employed in our regenerative lamp or lantern
which is admirably adapted for illuminating streets, parks, gardens, railway stations
and for other purposes.
Fig. 1 is a vertical section through the lamp or lantern, the skeleton frame of which
consists of appropriately bent tubes, which serve to conduct the heated air into the
lower part of the lantern from whence the said air is conducted to the flame.
Fig. 2 is a section of the lamp or lantern with the guide tubes for the products of
combustion and the heated air and the lamp and its mantle in elevation.
Fig. 3 is a horizontal section on the line A B.
Fig. 4 is a like section on the line CD, and Fig. 5 a like section on the line E F in
Fig. 1.
Fig. 6 is a part section and elevation of the burner and its connection with the
lamp reservoir and mantle on an enlarged scale..
The tubes d which are bent to correspond with the desired form of the lantern,
communicate at their upper ends with the tube e and at their lower ends with the
double hoitom a, which carries the lamp and its mantle c so that the heated air

page_text: passing through the said tubes d will flow into the space between the reservoir b and
the mantle c and through the perforations of the burner cap to the flame.
A tube, which is of funnel like shape at its lower extremity is movably inserted
in this tube e, and in this tube fa second tube h of like form but smaller in diameter
than the said tube f. The tube h is provided with wings g which are in contact with
the inner surface of the tube f, so that the tube I can be readily adjusted; the diameter
of the funnel like end to the same being so arranged that it corresponds with the
width of the flame, said tube / being open at its upper end and in communication with
the draught cap of the lantern.
The draught cap is arranged to fit over the tubular upper part of the lantern and
consists preferably of a square case or chimney of sheet metal around which a
casing m with wings is so arranged that the latter m can be readily adjusted on
the former l. A square box n inserted in the casing m serves to prevent downdraft
and for cooling the products of combustion.
By means of this draught cap I am able to regulate the draught to correspond with
the requirements of the flame.
с
The requisite atmospheric air for maintaining a bright flame enters the lantern
through the openings o just above the bottom of the lantern and through the
openings o Figure 2 in the glass of the same, passes as represented by the arrows
Figures 1 and 2 into the annular space formed between the tubes fand h where the
said air is warmed by coming in contact with the said tubes and co-mingling with the
heated air present and flows from thence through the tubes d into the hollow bottom
of the lantern and through the space between reservoir b and mantle c to the flame.
As shown in Figure 6 the air passing to the flame is compelled to pass through the
perforations
and through the customary sieve so that after having passed the
perforations in the distributing discs it reaches the flame correctly distributed.
The smokeless products of combustion which contain a large quantity of carbonic
acid pass in a most direct manner through the tube to the draught cap; the heat of
the said products being utilised as aforementioned for heating the air fed to
the flame.
Although we have only shown one form of lamp or lantern it will be evident to
those versed in this branch of industry that the various parts of the said lantern can
be modified in many ways without departing from the tenor of our invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
:-
1. A regenerative hydro-carbon lamp or lantern in which
combustion are led off direct through a special adjusted tube
purpose and arranged exactly above the flame, substantially as
foregoing specification and shown in the accompanying drawings.
