FREDERICK ROSENTIAL, of the Firm of F. Rosenthal and Company, of
No. 36, Mark Lane, in the City of London. "IMPROVEMENTS IN BURNERS FOR
LAMPS BURNING PARAFFINE, PETROLEUM, AND OTHER MINERAL OILS, AND HYDRO
CARBON FLUIDS." A communication from abroad by Max Berger, of Breslau,
Prussia.
This Invention relates to improvements in the burners to lamps burning
paraffine, petroleum, and other oils and liquid hydro carbons, and it consists
particularly in the use of a novel central air conduit with deflecting flange or disc,
whereby a very considerable quantity of cold air is conveyed to the interior of the
flame.
A current of air also passes to the interior of the flame between the wick 'tube
or holder and the aforesaid central air conduit.
The accompanying Sheet of Drawing shows a burner embodying the
improvements, the subject of this Invention."
Figure 1, being a sectional elevation of the burner with gallery and glass
complete.
Figure 2, elevation of burner.
Figure 3, section through central air conduit or supply pipe.
Figure 4, inverted plan of burner, and
Figure 5, section through sliding piece of central air pipe; A indicates the
wick-holder; B, central tube or air conduit; C, sliding piece with deflecting flange,
disc, or button; c, c', air holes communicating with tube B; D, disc or deflecting
flange; d, air hole in same; E, wick; F, air chamber through the perforations in
which air is supplied to the central tube B; G, opening through which air enters
between the wick tube E and pipe B from the perforated chamber H.
The arrows indicate air currents.
When this burner is lit, the disc D and the upper part of the tube B rapidly
become heated, and a strong suction or draught of air is established through the
chamber F direct to the interior of the flame, the effect of this isolated current
being not only a quick and perfect combustion of the parafline or other oil, but

page_text: also the production of an intense white light and the absence of all unpleasant
odour even when regulating the flame, which in this improved burner may be
regulated most minutely. Further, the cold air entering the box or chamber F
keeps the lower parts of the burner cool, as also the well ring and well in which
the developement of explosive gases is consequently diminished; the strong
current of cold air supplied by the special tube B has also this effect, that the pores
of the wick, less heated than in ordinary burners, are consequently less exposed to
carbonization, and long retain their power of suction or capillary attraction.
As an additional security against explosion, the bottom of the box or chamber F
may be supplied with apertures through which the gases from the well or reservoir
of oil may enter the said chamber and be conveyed by the cold stream of air from
without through the conduit B and by the disc or flange D into the flaine, so
that there can be no accumulation of gas in the well or reservoir.
