Title (EN) CHISEL
(FR) BURIN
Abstract:
(EN) A chisel for removing material (5) from a crack defined between two adjacent bricks, comprising a body (1) supporting an elongate tip (2) and defining shoulders (4) extending transversely of the tip. The width of the tip is less than the width of cracks from which it is desired to remove material, and the width of the shoulders is greater than the width of the cracks such that the shoulders limit the depth of insertion of the tip into the cracks. The shoulders may be fixed surfaces, which may be covered with or fabricated from materials which will not mark bricks across which they slide, or alternatively the shoulders may be defined by rollers (22).
(FR) Burin permettant de retirer de la matière provenant d'une fissure se trouvant entre deux briques adjacentes, comprenant un corps (1) supportant une extrémité allongée (2) et définissant des épaulements s'étendant transversalement par rapport à l'extrémité. La largeur de l'extrémité est inférieure à celle des fissures d'où l'on veut retirer de la matière, la largeur des épaulements étant supérieure à celle des fissures, de sorte que les épaulements limitent la profondeur d'introduction de l'extrémité dans les fissures. Les épaulements peuvent être des surfaces fixes qui peuvent être revêtues de ou réalisées dans des matières ne marquant pas les briques sur lesquelles elles glissent, ou en variante les épaulements peuvent être définis par des rouleaux (22).
