Abstract

206,941. Feldman, E. B. Aug. 22, 1922. Fastening sheets together by punching. - A hand-tool for fastening sheets of paper together by means of punched tongues which are drawn through a cut slit comprises jaws 1, 2, with integral legs 4, 5, pivoted on a pin 3, the jaws 1 having extended cheeks enclosing the punching- mechanism, and a cut-out portion into which a matrix 27 is fastened by a screw 28. A rocking frame, pivoted on a pin 7 to the jaw 1, is actuated on closing the legs, against the pressure of a spring 24, by an attached roller 23. The frame carries the tongue knives 12, a slit knife 22, and a rammer 13 pivoted on a pin 14. When the legs are pressed together the frame is rocked and the tongue and slit cut, the heel 19 of the rammer strikes a pin 26, fixed to the jaw 1, causing a lug 20 to force the cut tongue into an opening 22 in the knife 22. The rammer is held in its rotated position by a spring 15 until the lug strikes the matrix 27 during the restoring movement.
