ABSTRACT:
A hearth grate comprises a succession of transverse bars which are alternately fixed and movable with a reciprocating movement, said bars being formed by disposing in side-by-side relationship at vertical lateral faces elements which are generally rectangular, with a projection portion at the junction of a frontal face and a dorsal face and in the dorsal face blowing orifices opening in said projection portion.
The elements are held by the insertion into openings provided in the frontal faces of limbs of a fastener. The fastener comprises a transverse portion which is disposed in set-back relationship with respect to the frontal faces. Plate portions are welded over the openings to retain the fastener.
