Referring now to the drawing in detail, the in
vention will be fully described.
A burner tube is represented by 6 which ex
tends from a support 8. The support 8 is hol
low and is adapted for connection to a gas sup
ply system and the tube is closed at its left hand
end. Gas is emitted from the tube 6 through
a series of ports 1 along its upper side which may
be of any size desired and relatively arranged to
suit various conditions.

and the grooves of the strut acting on the notches
of the plates as described not only insure intimate
contact of the parts but provides a strong vrigid
construction wherein the plates and strut coop
erate to reinforce the tube against warping and
sagging._ Also the plates function for the con
duction of heat from the tube while at the same
time a free ?ow of air is facilitated around the
tube.
It may be desired to provide a series of open
ings 30 through the bar, as shown, in Fig. 6.
This will reduce the weight of the strut and per
mit air to pass through the strut which may be
considered necessary in some cases.
The parts may be made from various mate

A strap i2 encircles the outer end of the tube 6
and has side parts M that lie on opposite sides of

parts and strut has a nut l8 thereon to draw and

A plurality of relatively thin plates 22 are pro
vided which are provided with openings 23 in
their upper edges and upwardly extending
notches 24 in their lower edges.
.‘ Grooves 26 are provided on opposite side faces
of the strut IE1. These are spaced apart accord
ing to the spacing of the plates 22 as desired.

lation, as shown in Fig. 4, as are the bottoms of

The invention may be embodied in other spe
ci?c forms without departing from the essential
characteristics thereof. Hence, the present em
bodiments are therefore to be considered in all
respects merely as being illustrative and not as
being restrictive, the scope of the invention being
indicated by the appended claims rather than
' by the foregoing description, and all modi?ca
tions and variations as fall within the meaning
and purview and range of equivalency of the ap
pended claims are therefore intended to be em
braced therein.
What is desired to claim and secure by Letters
Patent of the United States is:
1. A burner of the class described comprising
in combination, a support member and a tube
member extending therefrom closed at its outer
the grooves 26 in the strut, as shown in Fig. 5.
The openings 23 in the plates 20 are such as 55 end and provided with ports along its upper side,

a strut supported by said members parallel to said
tube and below said tube. grooves in opposite side
faces of said strut spaced apart in pairs, plates
having notches in lower edges the sides of which
vided with ports, a strut spaced below and par
allel to said tube member having vertically dis
posed grooves in opposite faces thereof arranged
in spaced pairs therealong, plates having notches
are received in said grooves and provided with 6 in their lower edges and openings in upper edges
openings in upper edges through which said tube
member extends, the sides of said notches of the
plates and the bottoms of said grooves being sim
ilarly diverging whereby a wedging action thereof
through which said tube member extends, por
tions of said plates at the sides of the notches
received in said grooves, the bottoms of said
grooves of the strut and the sides of the notches
causes the upper side portions of the plates to be

tube is firmly gripped in the openings of the
wedging action in the notches of the plates to
cause upper side portions thereof to move in
