acter 20 represents an outer annular casing of 35
a lantern base into which the oil receptacle 2!
rests. The casing 20 has air openings 20’ as is
usual in this'type of base. The receptacle 2| is
provided with a font cap 22 which has the wick
tube 2-3 surmounted by the burner 24. It will be 40
understood that the outer structure of the Iantern may be any of a number of types or the burn
er 24 may be applied to a lamp, cigarette light
er or other lighting or igniting device and when
used as a lantern the top dome may be any of 45
a number of types.
Mounted at the ‘top of the wick tube 23 is a
pan 25 which as shown in Figures 3 and 6 has a
central opening 26 through which the upper end
of the wick projects and the pan extends some 50
distance laterally and longitudinally from the
wick.
The dimensions of Figures 1 to 6 as well as the
other ?gures of the drawings are in correct pro
portion to those of actual structures employed 5:;

v45 rows in Figure ll, the plates or barriers 28 will
prevent the blowing out of the ?ame by a draft
entering between the skirts; whereas the current
of air over the end plate of the skirt will be direct
‘over the ?ame. By the form of the passage be
tween the skirt and plates 21 the air passes up

plates is such that the air passes smoothly along
them without the creation of excessive eddies.
To prevent the possibility of such eddies put

The ba?le shown in Figures 18 and 19 may be
obviously, if desired, applied to any of the forms 50
of burners disclosed as well as other burners now
in use.
tinguishment of the ?ame will be limited to that
wardly and upwardly gradually curved passage
part on one side of the ba?le and immediately
meeting the base of the ?ame at an acute angle,
a barrier to prevent ?ow of air to the base of said
?ame at each end, and means supplying air to the
ends of said ?ame at a higher elevation, said
latter means comprising guiding walls curving
inwardly and upwardly and meeting the ?ame at
an acute angle.
2. In a burner, a wick holder, a pan surround
ing said wick holder, metal side sheets secured
at their topv to the top of the pan and bent'con
vex to the pan and of gradually increasing curva
ture as the pan is approached and a skirt sup;
ported above said pan, said skirt being formed of
side and end sheets, said last mentioned side and
end sheets being of substantially the form and
curvature of said ?rst mentioned sheets.
3. The structure claimed in claim 2 wherein
when the draft has ceased, the part of the ?ame
which is still burning will relight the part that has
been extinguished. This ba?le as clearly shown
in these ?gures is a thin plate formed with sup
porting legs 36 suitably secured to the top of the
65 pan 25 midway of the length thereof. A similar
baffle can be supported from the skirt 29 of the
form of invention shown in Figures 1 to 6. In
the form of invention shown in Figures 18 and 19,
a single skirt 3'! is employed which is secured at
70 its top to the top of the pan. In order to func
tion satisfactorily, the lower edge of the ba?le 35
should be spaced from the bottom of the pan or
the wick at about the distance shown in Figures
l8 and [9, that is, less than 1% of an inch.

tional. sheets curving gradually inwardly and

10 at an elevation above said skirt.
5. In a burner, a holder for a wick elongated
in cross section,‘ a pan surrounding the top of
said wick holder, metal end sheets secured at
their top to the top of the pan, the sheets ex
15 tending down from the pan and the sheets be
ing bent convex toward the pan and a baffle plate
extending transversely of the flame area at an
intermediate point of the flamev length and at a
slight elevation above said pan.

6. In a burner, a wick holder, a pan surround
ing said wick holder, metal side sheets secured
at their top to the top of the pan and bent convex
to the pan and of gradually increasing curvature
as the pan is approached, and a skirt supported
25 above said pan, said skirt being formed of side
and end. sheets, said side sheets being of sub
stantially the form and curvature of said ?rst
mentioned sheets.
7. The structure claimed in claim 2 wherein a
barrier is interposed between the ends of the
pan and the skirt.
8. The structure claimed in claim 2 wherein
the barrier is interposed between the ends of
the pan and the skirt, and wherein additional
side sheets are provided located above said skirt
and having a form similar to the side sheets of
said skirt.

9. The structure claimed in claim 2 wherein 10
there is provided additional side sheets located
above and spaced from said skirt, said additional
sheets curving gradually inwardly and upwardly.
10. In a burner, a holder for a wick elongated
in cross section, a pan surrounding the top of the 15
wick holder, metal side sheets secured at their
top to the top of the pan, the sheets extending
down from the pan and the sheets being bent
convex toward the pan, other side sheets located
above said ?rst named sheets, said last named 20
sheets being bent downwardly and outwardly
convex toward the pan, and a baffle plate extend
