along the lline XI-XI in Fig. 1 and looking in
cessfully accomplished by increasing the depth

is fa plan Y view of the burner base plate and
of the burning ports and by making them as
15' narrow as shop practice ’would permit.A However,
the deep narrow ports occasion considerablere
sistance to the flow of gas and it is thereforede
sirable to make the sides of the ports smooth and
free from rough projections. 'The narrow slotted
20 ports, however, prevent the flame from travel
ing back down through them, which sets up a
definite resistance to ñashback.
The additional depth of the burning ports by
increasing the area of metallic surface contacted
25 by the air-gas mixture during its flow from the
orifice to the burning edge, presented the possi
bility of heating the air gas mixture to such an
extent that excessive pressures would result with
in the burner box. I overcome this tendency by
30 cooling the burner head, this is done by bringing
the secondary air for combustion up between the
ports; this feature also furnishes a further ad
vantage in that it gives a desirable distribution
of such secondary air throughout the entire ñre.
To recapitulate; my improved gas burner in
35
cludes an increased area of cooling surface on the
Venturi ~`tube integral therewith.
VSimilar nu
merals» of ' reference designate the same pa'yrt
throughout the several figures of the drawing.
Referrlng'fto the drawing, Yat Ill are the base 20
casting walls, integral with an intermediate cast
T-pipe fitting II provided with a jet I2. A rec
tangular shaped upper portion I3 is also integral
with the side walls I0 and at the four corners
thereof may be seen corner elements I4 and a 25
raised triangular portion I 5. Upon the base seen
in Fig. 8 and just described, I next assemble the
element seen in Fig. 7 which has a base member
I6 as a plate supported by the four corner ele
ments I5. Integral with the member I6 is a 30
Venturi tube I'I extending a little below the base
I6 as at I'Iœ and upwardly the height desired as
seen in Figs. 9, 11, and 12. This Venturi tube
may be surrounded by the wall element I8 as
shown Figures 1, 2, and 11 in which case a slotted 35
projection I9 would occur at the upper part of
from a study of the drawing and as amplified
the end walls for purposes later explained. I
next assemble an inner box-like element 20, open
at its lower end and surrounding the Venturi tube
I'I as disclosed in Figs. 6, 9, 11, and 12. The lower 40
end of the element 20 is provided with a pair of
centrally disposed extensions 2| and a pair of
centrally disposed extensions 22, thus providing

proved secondary air distribution to the' fire.
These and other advantages will be apparent
Fig. 1 is an end view of a single burner; it being
understood my burner may be employed in mul
tiple units if so desired. Fig. 2 is a side elevation
of the burner shown in Fig. 1; a portion of the

admitted through the jet I2, tube I'I and passage

the element 20 and the outer side walls I8. It
will be noted that the upper end of the element
20 is closed by an inverted V-shaped roof portion 50
as seen at 21.
The assemblage shown in Figures 1 and '7 just
described is now ready to receive the burner ele

It will be noted in the several
