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. with a new and perfec connecting rod system tiated and allowing better yields and perfor mances than the devices known so far.

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. It saves time and labor and perform work inaccessible to machines fitted with conventional devices, in particular thanks to the possibility of using the jaws separately.

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. The figures in drawing sheets 1 and 3 show the different parts of the new system, as well as their position when the jaws are closed or or green.
