Pliers for punching cards or tickets

Abstract

A pair of pliers is provided for perforating small cards, which pliers have two double-arm levers which can be pivoted about a geometrical transverse axis and whose end zones, which serve for perforating, each have a plane, which planes are parallel to the transverse axis and which, in the closed state of the pliers, are approximately parallel to each other. Vertically positioned in one plane is at least one punching pin, to which there corresponds in the opposite end zone a punched hole which is vertical to the plane of the latter. There are provided two positioning pins in one end zone vertically to the plane thereof, which pins are, measured in one of the two main planes, at a specific center distance from the transverse axis. In one end zone, there is provided a first coding box and in the other end zone, there is provided a second coding box, which boxes contain the punching pin and the punch hole respectively, the coding box being sufficiently smaller in dimension, with respect to symbol identification, in the direction that is parallel to the positioning pins than the positioning pin.
