Claims5
A cutting guide for producing custom mats comprising:
- an elongated base having a straight longitudinal side edge for registering with one outside edge of a mat to be cut;
- elongated scale means pivotally secured to said base and projecting normal to said straight longitudinal edge for guiding a knife device moved along said scale means in a direction perpendicular to said straight longitudinal edge of said base, and for indicating the length dimension of a cut made in said mat, and the location thereof in relation to said straight longitudinal edge and said one registering outside edge of said mat;
- first adjustable stop means carried on said elongated scale means, and adjustably positioned along the length of said elongated scale means to selectively limit the distance a knife device can be moved along said scale member in a direction perpendicular to said straight longitudinal edge of said base;
- second adjustable stop means secured to said base at a location along said longitudinal side edge and selectively positionable at varying distances from said scale means for locating a second outside edge of a mat extending perpendicular to said first-mentioned outside edge;
- and
- second scale means secured to said base and having graduations thereon visually correlatable with the position of said second adjustable stop means to indicate the dimension of the border of a mat formed by moving a knife device along said first-mentioned scale means in a direction perpendicular to said straight longitudinal edge of said base.
