Fig. 1; Fig. 4 is an elevational view of one plate of the burner shown in Fig. 1; Fig. 5 is a transverse sectional view through the longitudinal strut of the burner; and Fig. 6 is a partial plan view of the strut of the burner. , 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. 1 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 i A strut I6 is provided which is arranged at its inner end for securement to the support 8 as shown in Fig. 1. desired spacing of the plates 22.

A screw l6 passing through the side parts and strut has a nut l8 thereon to draw and hold the parts together. 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. The sides of the notches 24 in the plates 22 are preferably arranged in} downwardly diverging re lation, as shown in Fig. 4, as are the bottoms of rials but aluminum has ‘been found to be desir- ' able for the practice of the invention, 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, 2,409,421 3 4 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 of said plates arranged in downwardly diverg urged inwardly towards one another so that said - ing relation whereby said strut functions with a‘ 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 wardly towards one another to ?rmly clamp the tube member in the openings thereof. plates. 2.
