Abstract (en)
[origin: US4776287A] 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.
Abstract (fr)
La grille de foyer comporte une succession de barreaux transversaux, alternativement fixes et mobiles en va-et-vient, ces barreaux étant formés par accolement suivant des faces latérales (109, 119) verticales, d'éléments tels que (10) et (11), généralement rectangulaires, avec au raccordement d'une face frontale (101) et d'une face dorsale (102), et sur cette dernière une saillie dans laquelle débouchent des orifices de soufflage (103d). Les éléments (10, 11) sont maintenus par insertion, dans des logements (104, 114) pratiqués dans les faces frontales (101, 111), de branches (20, 21) d'une agrafe (2). Cette agrafe comporte une traverse (22) qui vient en retrait des faces frontales (101, 111). Des plaquettes (30, 31) viennent se souder sur les logements (104, 114) pour retenir l'agrafe (2).
