"Improvements in or relating to Incandescence Oil Burners."
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 322, High Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street Birmingham, in the County of Warwick, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
The present application relates to improvements in the construction of petroleum
lamps adapted for incandescence lighting of the type forming the subject of previous
applications for Letters Patent by me.
In the present application the same result as has been obtained by causing a weak
stream of air to pass over the inner edge of the wick, a strong current passing the
outer edge of the same, and a central current not contaminated with combustible
gases and caused to pass over the place where combustion takes place and to be
conducted to the flame sideways, if the therein described tubular piece inserted in
the upper part of the wick tube, which was designed to divide the central air current
into two separate streams, be entirely omitted and in place thereof a baffle or disc of
the usual kind be inserted above the wick tube. The said baffle bears on its
underside a perforated tube, the lower end of which is open and has a lip or edge
projecting over the wick; the central air current rising up the wick tube is hereby
caused to pass for the most part into the open lower end of the tube attached to the
baffle, because the same lies in direct continuation of its direction; only a com-
paratively very small portion of this central air current escapes sideways underneath
the projecting edge of the tube and between the same and the edge of the wick, and
developes combustible gases from the wick which are carried away by the outer
strong air current within the cap of the burner. The greater part of the central air
current which as already stated passes into the interior of the tube attached to the
baffle, passes out of the side perforations of the said tubular piece (which is entirely
closed above by means of the baffle), and is thereby conducted to the flame.

I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.L.M.E., of the Agency for Foreign
Patent Solicitors,-322,-High-Holborn, in the County of Middlesex, 6, Lord Street,
Liverpool, and 6, Bank Street, Manchester, both in the County of Lancaster, and
Lower Temple Street Birmingham, in the County of Warwick, Civil Engineer,
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.
The present application relates to improvements in the construction of petroleumn
lamps adapted for incandescence lighting of the type forming the subject of
previous applications for Letters Patent by me.
The
In the present application the same result as has been obtained by causing a
weak stream of air to pass over the inner edge of the wick, a strong current passing
the outer edge of the same, and a central current not contaminated with combustible
gases, and caused to pass over the place where combustion takes place and to be
conducted to the flame sideways is obtainable if the therein described tubular piece
inserted in the upper part of the wick tube, which was designed to divide the
central air current into two separate streams, be entirely omitted and in place
thereof a battle or disc of the usual kind be inserted above the wick tube.
said baffle bears on its underside a perforated tube, the lower end of which is
open and has a lip or edge projecting over the wick; the central air current rising
up the wick tube is thereby caused to pass for the most part into the open lower
'end of the tube attached to the baffle, because the same lies in direct continua-
tion of its direction: only a comparatively very small portion of this central air
current escapes sideways underneath the projecting edge of the tube and between
the same and the edge of the wick, and developes combustible gases from the wick
which are carried away by the outer strong air current within the cap of the burner.
The greater part of the central air current which as already stated passes into the
interior of the tube attached to the baffle, passes out of the side perforations of the
'said tubular piece (which is entirely closed above by means of the baffle) and is
thereby conducted to the flame.
Referring to the accompanying drawing in which the invention is illustrated in
section, the perforated tube A is supported at the proper height above the wick
tube D by means of the tubular or solid rod F. The said rod F is supported
centrally within he annular wick tube D by cross pieces H or the like and bears at
its upper end the baffle E of ordinary construction. The perforated tube A has at
its lower end a channel or recess in which is fitted the flat circular ring a serving
to divide the air currents in the manner already set forth, and prevent too great an
access of the main current of air to the root of the flame. The outer cone B is of
usual construction. Air may be supplied within the annular wick tube through the
triangular aperture K or otherwise. Means are provided for supporting the mantle
over the burner as usual in lamps of this class. The baffle E, perforated tube A and
support F are conveniently made removable so that in case of need the lamp may at
any time be converted to a white flame lamp by the removal of the said apparatus,
and the insertion of a baffle of ordinary construction such as is used for white
flame burners.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
In a blue flame burner for incandescence oil lighting :-
:-
1. An apparatus for dividing the air currents passing to the flame consisting

page_text: essentially of a central support, a solid baffle, a perforated tube of diameter approxi-
inately equal to the diameter of the wick tube, attached at its upper end to the solid
baffle, and having its lower end open, and an annular ring projecting from the lower
edge of the said perforated tube, substantially as described.
2. The improved burner constructed and operating substantially as described and
