with the oil vapor from the wick. The re-
suit of this mixing of the air and oil vapor
by this means is the production of a very
brilliant flame of great illuminating power
5 with no increase in oil consumption, on ac-
count of the very complete combustion. of
the oil vapor.
As will be noticed from Fig. 2 of the
drawings, the casing has its upper side edges
10 of arcuate shape and curving downwardly
toward each end of the casing from the
longitudinal center thereof. This results in
the ends of the casing being somewhat lower
than the center of the casing so that the
15 lamp flame, in its endeavor to extract the.
maximum amount of oxygen from the air,
will tend to spread downward from each end
of the wick tube, thus producing a very
broad rounded flame having a relatively
20 large surface and capable of producing a
large amount of illumination.
A flame cap 10 is hingedly secured to the
burner base as at 18. This cap is provided
with the usual transversely extending slot
25 19 for the flame and acts to insure a steady
and clear flame and to supply air to the
flame above the top of the wick, in the usual
manner. In normal position this cap is se-
cured over the wick tube 3 and casing 8
30 by means of a spring hook or finger 20
which engages through a slot 21 formed in.
the burner base.
I am aware that it has been proposed to
produce lamp burners having an air duct
35 or casing mounted about the wick tube for
supplying air to the flame but, so far as I
am aware, it has never been proposed to
produce a casing which is detachably mount-
ed about the wick tube and is provided with
40 means engaging with the tube for holding
the casing in operative position, this casing
being so constructed and shaped as to pro-
duce a very broad flame of maximum illumi-'
nating capacity.
45 What I claim is:
1. In a lamp burner, the combination of
a wick tube provided at the center of one
side with a vertically extending seam, and. a casing mounted about the tube in spaced
relation and concentric therewith provided, 50
at the center of the lower edge of each side,
with an integral inwardly turned tab hav-
ing a recess adapted to snugly receive the
seam of the wick tube, the upper edge of
each side of said casing being of arcuate 55
shape and curving downwardly from the
longitudinal center of the casing toward the
end of the casing.
2. In a lamp burner, the combination of a
wick tube provided at the center of one side 0
with 'a vertically extending seam, and a cas-
ing mounted about the tube in spaced rela-
tion and concentric therewith provided, at
the center of the lower edge. of each side
wall, with an integral inwardly extending 65
tab having a recess in its inner end adapted,
to snugly engage about the seam of the wick
tube, the casing being further provided w:th
a plurality of spaced apertures in each side
and having the upper edge of each side wall 70
of arcuate shape and curved downwardly
from the longitudinal center of the casing
toward each end of the casing
3. An attachment for lamp burners com-
prising a casing adapted.to be mounted in 75
concentric space relation to a w ick tube hays
ing at the center of the lower edge of each
s'de wall an inwardly extending tab pro-
vided with a recess in its inner end adapted
to snugly receive the seam of a ivick tube, 80
the under faces of said tabs being flush with
the lower edge of the casing whereby the
lower end of 'said casing will rest directly
on the gallery of a lamp burner when in
operative position, said casing having 'the 55
upper edge of each side wall of arcuate
shape and curved downwardly from the
longitudinal center toward each end of the
casing.
In testimony whereof I affix my signature 90
in presence of two witnesses.
