ABSTRACT:
Lightweight, portable apparatus for cutting a wide range of materials available in sheet form, such as matboard, glass, light plastic, and leather. The invention lies in the unification of its cutting tool guide tract with the means of fixing in place the material to be cut. Four pegs are attached to the base of the apparatus for aligning the sheet to be cut. Equally important is the means by which it is automatically held in place during the cutting operation. Pieces of foam rubber or the like are inlaid in the base of the apparatus so that when the operator is pressing down on the cutting tool the resultant force normal to the supporting surface is sufficient to prevent lateral motion of the apparatus. Thus, no bulky and awkward clamping devices need to be used to affix the cutter to its supporting table. The apparatus also can be quickly converted into a T-square by attaching a cross-piece which mates with the base of the apparatus and in so doing defines a right angle with the combined guide track clamping plate.
