My invention relates to improvements in lamp
burners of the type adapted for use in hand lan
terns, and other lamps, and the same has for
its object to provide a simple, efficient and re
liable burners capable of producing a large bright
?ame which will burn without smoking or ?ick
Further, said invention has for its object to
provide a burner in which the ?ame spreader
10 is capable of producing a larger ?ame of greater
lighting power or luminosity for a given size of
wick than would be possible‘ to obtain in the
absence of such ?ame spreader.
Further, said invention has for its object to
“ provide a device of the character speci?ed in
which the ?ame spreader is constructed to main
tain a predetermined height of the ?ame and to
minimize the tendency of the ?ame to be drawn
upwardly or “creep” as the lamp heats up, and
which will permit of the lantern being used for
heavy signaling without causing ?ickering or
Further, said invention has for its object to
provide a device of the character speci?ed in
which the ?ame spreader is constructed to cause
the air for supporting combustion to be directed
towards the ?ame in directions extending more
or less transversely thereof and to minimize the
force and effects of ascending air currents upon
the ?ame.
Further, said invention has for its object to
provide a device of the character speci?ed in
which the primary air introduced for supporting
combustion is combined with a series of jets of
C: 91 supplementary air directed inwardly and down
wardly into the ?ame.
Further, said invention has for its object to
provide a device of the character speci?ed in
which a combined ?ame spreader and baffle serve
to reinforce each other to form a strong, rigid
Other objects will in part be obvious and in
part be pointed out hereinafter.
To the attainment of the aforesaid objects
45 and ends my invention consists in the novel fea
tures of construction, and in the combination,
connection, and arrangement of parts herein
after more fully described and. then pointed out
in the claims.
In the accompanying drawing:
Figure 1 is a side view of one form of burner
constructed according to and embodying my said
Fig. 2 is an end view thereof;
Fig. 3 is a plan thereof;
Fig. 4 is a vertical section taken on the line
4—4 of Fig. 1;
Fig. 5 is a horizontal section on the line 5-5
of Fig. 2;
Fig. 6 is a detail perspective view of the ba?ie
member detached from the burner, and
Fig. 7 is a face view of the blank from which
the ba?le member shown at Fig. 6 is formed.
In said drawing, the base portion In of the
burner is provided with a lower reduced part II 10
having vertically and circumferentially extend
ing grooves I2 and 13 therein serving as means
for locking the device into the oil font of the
lamp. The base portion 10 at its upper end,
has a horizontal ?ange l4 and a central dome 15
shaped portion iii. A flat wick tube I6 is dis
posed centrally within the base portion lll and
dome-portion l5, and has its lower end project
ing slightly below the bottom of said base por
tion. The upper end of the tube 16 projects
above the dome portion i5. The tube i6 is pref
erably constructed from a piece of sheet metal
having the vertical edges thereof interlocked as
shown at IT.
The base portion In below. the ?ange I4 is
provided with aligned holes l8 serving as bear
ings for the wick raising shaft 19 having star
wheels 20 extending into the Wick tube IS‘.
The ?ame spreader 2! is preferably formed
from a piece of sheet metal and includes the .
standards 22 for supporting the spreader 2! upon
the ?ange M. The lower ends of the standards
are provided with prongs 23 extending through
slots 24 in the ?ange l4 and bent over whereby
the ?ame spreader 2| is secured in place upon K.
the ?ange. The upper part of the ?ame spread
er 2i comprises the ?at side portions 25 and 26
formed integrally with the upper ends of the
standards 22; the side portion 25 being integrally
connected at both ends with the standards 22,
and the portion 26 being integrally connected to
one standard at one end and having a free end
portion 21 directed inwardly and overlapping ‘the
other standard at the inner side thereof. The
side portions 25 and 26 are formed to‘ extend
upwardly and inwardly at opposite sides of the
broad sides of the tube It and are perforated
as shown at 28, to provide upon each portion
25 and 26 a multiplicity of jet openings through
which air passes to be discharged in relatively 50
small jets directed inwardly and downwardly to
wards the upper end 29 of the wick tube IS. The
upper portions 30 of the standards 22 provide
imperforate vertical end walls disposed trans
versely of the portions 25 and 26 at the ends 55
thereof and forming therewith an enclosure 3|
which is of progressively increasing rectangular
cross-sectional area towards the base thereof.
The upper edges 32 of the portions 25 and 26
are convex with the result that the mouth 33
of the enclosure 3| is of progressively increasing
width from the center to the ends thereof. The
mouth 33 is relatively enlarged in area compared
to the area of the mouth 29 of the wick tube1|6
and is disposed symmetrically with reference to
and in elevated relation to said mouth 29. _
The enclosure 3| is reinforced by a baffle mem
ber 34 formed from a piece of sheet metal stamped
out and bent to provide a horizontal or trans
verse imperforate partition or baille plate 35 sur
rounding the wick tube |6 at points slightly below
the mouth thereof, a suitable opening 36 being
provided in said ball‘le portion 35 and conforming
in shape to and ?tting the tube l6. Theportion
35 substantially ?ts the enclosure 3| slightly above
the lower edges of the. plate portions 25 and 26.‘
The ba?le 35 has up-turned ?ange ‘portions 31
and 38 at the ends‘ thereof engaging the end
The structure embodying my invention allows
the'use of a poorer grade of kerosene without
causing smoking, and permits of the use of signal
lanterns for heavy signaling, involving jarring and
sudden movement. and stoppage of movement of
the lantern without causing ?ickering or ex
tinguishing of the ?ame.
In the operation of the lamp the ?ame spreader
2| including the bail‘le 34 serves as an automatic
control for maintaining the ?ame at the desired
height and preventing the drawing up or ?icker
ing of the ?ame liable to occur when strong up
draft currents develop as the lamp heats up.
obviate updraft currents by the construction em
bodying the present invention.
' The ba?lermember 34 also serves to reinforce
the enclosure 3| internally, and to anchor the
same to the wick tube l6 at the upper end thereof,
thereby forming a strong, rigid and durable

The corner
portions'of the ba?le plate 35 are up-turned, as
indicated at 40, about longitudinally extending
lines of bends 4| substantially in vertical align
ment with the upper edges 32 of the portions 25
and'26, and provide four openings 42 through the
baffle plate substantially at the four corners of
the enclosure 3| for the passage of air to the
The air ~ currents passing vertically
through the openings 42 at each side are directed
inwardly towards each. other by the baffle por
tions 46 and are discharged through the outlet
openings 43 formed by the baille portions 40 and
walls 25 and 26, the latter serving to deflect the
incoming currents of primary air downwardly
towards the ?ame as the jets of supplementary
air induced through the openings 28 arecaused
to unite and combine therewith. The opposite
longitudinal edges of the baffle 35 are also pref
erably recessed at 44 to provide central openings
45 at the inner sides of the de?ecting plates 25 and
26 for the introduction of additional air which
is also de?ected inwardly and downwardly by the
plates 25and 26 and subjected to the air jets.
In my invention the ?ame is insulated against
vertically ascending air currents by the imper
forate barrier 35, all of the vertical openings 42
and 44 thereof .being outside of the downward
vertical projection of the edges. of the mouth 33
of the enclosure 3|. The air currents are de
?ected inwardly and downwardly towards the
?ame at the ?at sides thereof by the de?ectors
25 and 26, while being acted upon by the air
jets through the openings 28. The inwardly de
?ected air currents are concentrated by the ver
ticalfba?‘le portions 46 upon the ?ame vertically
below the reduced central portion of the ?aring
mouth 33 to improve combustion and produce a
bright, steady and intense ?ame.
