Abstract

335,826. Krogsgaard, O. M. Dec. 2, 1929. Jointing by stamping. - Overlapping metal plates are joined by punching a hole with a polygonal punch c bending back the lips so formed by a conical punch e and finally pressing them back against the plate by flat faces g, h. Applications described are for plates used in dentistry, and in the manufacture of toys. An adjustable screw may limit the closing movement of the jaws of the tool.
