The sides 2n of the bar section. Vgrate bar sections are disposed the same distance Referring to the drawing throughout Whieii apart as are the sides l2 of the grate bar frame,

The ends are provided with semi-anthe sections fit into the V-shaped depressions I'l nular recesses l5 cut in from their bottom edges. of the frame sides I2. Said projections, being These recesses t onto the shoulders I0 of the more obtuse than saiddepressions, the flat end head supports il leaving sufcient space for longiportions 26 of the sections rest on the` flat surfaces 55 I9 of the frame projections I8. This arrangement leaves spaces 21 between said depressions and projections for the entry of air, and the upper edges of the frame sides are beveled to facilitate the entry of air through these spaces. An end bar 2| of the end grate sections is cut away at 28 to also permit the entry of air as shown in Fig. 5. Said end bar may merge into the next bar 2|, as shownat 29, for the purpose of making a rectangular end on the outside of the end grate sections so that they will t snugly against the end flange 9 of the head support 6 as shown in Fig. 1.
It will now be apparent that I have provideda grate bar that is durable, which may be readily assembled and taken apart, which allows for ample circulation of air, and which -is amplyreenforced against warping. I-Iaving thus described my invention, it being understood that minor changes may be resorted to in its construc- `tion Without departing from the scope and' spirit of the invention, what I claim and'desire to 'secure by Letters Patent of the UnitedStates 1. A grate bar comprising head supports,` a grate bar frame supported by the head supports, the upper edges of the frame having V-shaped depressions therein, a plurality of grate bar sections supported by the frame, said sections having depending V-shaped projections that fit into the depressions of the frame, and said projections being more obtuse than the depressions whereby spaces are left between the projections and depressions.
2. A grate bar section comprising sides with depending V-shaped projections, a plurality of parallel bars disposed in diagonal relation with respect to the sides, the central bar extended to the bottom of the depending V-shaped projections to form a partition, and a bar on each side of the partition extended below the depending V-shaped projections to form depending fins.
3. A grate bar comprising head supports, a grate bar frame supported by the head supports and consisting of rectangular sides and ends, the top edges of the sides having V-shaped depressions with short lat portions therebetween, the opposing depressions of the respective sides being oiiset from each other longitudinally of the frame, and a plurality of grate bar sections comprising diagonal bars and depending sides having truncated V-'shaped projections adapted to be mounted on said frame with said depending sides tting in said depressions and leaving air cireulating spaces between the bottom of said depressions and the truncated ends of said depending sides.
