Abstract

La présente invention concerne des perfectionnements aux mitres de cheminées, c'est-à-dire le dispositif qui coiffe le conduit de fumée ou d'aération dépassant le toit. Les perfectionnements sont caractérisés par le combinaison : - d'un déflecteur montant extérieurement jusqu'au bord du conduit; - et d'un chapeau sensiblement plat, recouvrant le déflecteur et le conduit, de dimension pratiquement identique au déflecteur, ledit chapeau ayant une forme qui, en liaison avec ledit déflecteur, guide l'écoulement du vent suivant une veine qui se rétrécit et s'élargit successivement et, en tous cas, s'incurve, avec sa concavite vers le bas, au-dessus de l'ouverture du conduit
