COMPLETE SPECIFICATION.
Improvements in Apparatus for Burning Heavy Mineral and
other Oils.
I, LASSLO CHANDOR of No. 60 Gorochowo in the City of St. Petersburg in the
Empire of Russia, Gentleman, do hereby declare the nature of my said invention
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 improvements in apparatus for burning heavy mineral and
other oils as shown and described in the letters patent No. 10234 granted to me on
the 23rd August 1885, and concerns special appliances to ensure an even and steady
flow of air to the two flames which burn independently of each other.
Figure 1 is a vertical section of the improved Candlestick.
Figure 2 is a horizontal section on the lines A-B in Figure 1.
Figure 3 is a view of the candlestick with somewhat modified glass fittings.
In order to obtain a steady flow of air to the upper flame b, which is fed by the
combustion of the lower flame a and to previously properly warm the said air, a similar
arrangement described in claim 3 of Patent No. 10234 is used, with this difference,
that instead of the tightly fitting mantle over the perforated metal cylinder with an
inner gauze lining, a metallic ground or milk glass or porcelain cylinder c is used
which however is not provided with air holes at the top, but is inserted in a circular
cap or rim d, which is provided with air holes e. The air passing through these holes
is warmed by coming in contact with the hot perforated metallic cylinder and also by
the porcelain or other tube c and subsequently reaches the flame in heated condition
and causes it to give a white bright light.
The supply of air to the lower flame a is conducted in the following manner :-The
wick tube is concentrically surrounded by the tube g, which said tube is soldered to
the burner, and the space between the tubes ƒ and g brought into communication with
the atmospheric air by means of the opening or openings h in the burner. A further
improvement in the candlestick consists in the application of a small tube i which is
soldered into the burner and reaches down into the reservoir and serves to lead any

page_text: gases which might accumulate above the hydro carbon or other oil to the lower
flame
for the purpose of combustion and also to prevent the formation (by atmo
spherical mixture) of any explosive compound.
a,
To ensure a steady combustion of the flame the candlestick is provided with a glass
chimney, the end of which is either fitted into the chimney gallery k on the porcelain
tube c, Figure 1, or on the burner, Figure 3.
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.
1. In the so called Tischolin candlestick for the combustion of hydro carbon or
other oils as protected by Patent No. 10234, the substitution of a metallic porcelain
or glass cylinder c fitting into a circular cap or rim d provided with air holes for
the tightly fitting mantel with air holes at the upper end, as described in claim 3,
Patent No. 10234, substantially as described in the foregoing specification and shown
in the accompanying drawings.
2. In the so called Tischolin candlestick for the combustion of hydro carbon or
other oils, the application and employment of the tube g concentrically surrounding
the wick tube, to supply air to the flame a by means of the opening or openings h
and the space between the tubes fand 9, substantially as described in the foregoing
specification and shown in the accompanying drawings.
3. In the Tischolin candlestick for the combustion of hydro carbon or other oils,
the application and employment of the small tube i for leading off any gases which
might accumulate in the reservoir from the said reservoir to the lower flame,
substantially as described in the foregoing specification and shown in the accom-
panying drawings.
