17,501. Du Boulay, J. Dec. 20. Scissors. -- In addition to the ordinary turning motion of the blades a sliding motion is imparted. The lever A has a curved slot C and a concentric curved edge D, while the lever B has a stud E engaging the slot C and two pins F in contact with the curved edge D. The lever A is thus constrained to slide as well as turn relatively to B.Cataloged By
