ABSTRACT:
A glass cutter of the type having a pillar post capable of limited angular movement about a vertical axis is disclosed. The pillar post is provided in a conventional head which is adapted to traverse a glass sheet in one and an opposite direction, and the glass cutter can score in both directions because the tool is designed to trail this vertical axis, and thereby provide a castering action in both directions. The tool is mounted in a small pendulum which is gravity biased to assume a ready position such that traversing movement of the head and pillar post in one direction, in conjunction with engagement between the tool and the edge of the glass sheet itself, moves or swings the pendulum to a first limit position such that the tool trails the said vertical axis achieving the above castering action. Traversing movement of the head and pillar post in the opposite direction swings the pendulum to a second limit position which is the mirror image of the first position achieving a castering action during return movement of the head.
