Abstract

comportant un système de bielles nouveau et perfec­ tionné et permettant de meilleurs rendements et perfor­ mances que les dispositifs connus jusqu'à présent.
Il permet de réaliser des économies de temps et de main-d'oeuvre et d'effectuer des travaux inaccessibles aux engins munis des dispositifs classiques, notamment grâce à la possibilité d'utiliser les mâchoires séparément.
Les figures des feuilles de dessin 1 et 3 indiquent les différentes pièces composant le nouveau système, ainsi que leur position lorsque les mâchoires sont fermées ou ou­ vertes.
