Abstract

26,027. Gessler, M. Nov. 13. Fastening sheets together by punching.-A paper-fastening punch has a U-shaped knife 20 with the bent portion wider than the parallel portion, another U-shaped knife 21 adapted to cut an opening in the paper adjacent to the tongue cut by the first knife and narrower than the enlarged free end of the tongue, and a hookshaped locking-finger 23 pivoted between the parallel sides of the knife 20 and having a projection adapted to be engaged by a cross-bar 25 on the stripper plate 19, to cause the finger to rotate against the action of the spring 24 to force the enlarged head of the tongue through the opening cut by the knife 21, as shown in Fig. 7. The knife 21 has its sides cut away above its cutting-edges to form hook-like side parts to assist in positioning the enlarged heads of the tongue if this is not completed by the locking-finger. In the modification shown in Fig. 10, the cross-bar 25 is omitted, and the locking - finger has a pin 28 to engage the stripper plate 19 at the sides of the opening.
