Abstract
Abstract The mat cutting apparatus includes a cutter for making a bevel cut and an adjustable edge guide having a vertical straight edge surface with which a vertical flat surface on the cutter is slidably engaged as the cutter is pushed along the edge guide to make a straight, beveled cut parallel to one edge of the mat. When used to cut an opening in a mat for mounting pictures or the like, the outline of the picture is traced on the back of the mat parallel to the edges thereof and then the mat is secured face down on the edge guide with the straight edge surface positioned adjacent and parallel to one traced line. The cut is made from the back surface of the mat such that the cut through the front mat surface registers with the traced line on the back mat surface. The mat is turned, the edge guide repositoined and the cutting process repeated until the mat opening is cut out completely. No measurements need be made when using this cutting procedure; however the edge guide also includes indicia by which the border about the mat opening can be sized.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
Apparatus for cutting a flat article having a rectilinear edge comprising: cutter means for making a cut in the article; platform means for supporting the article, said platform means including rectilinear shoulder means upstanding therefrom for engaging and positioning the rectilinear edge of the article; cutter guide means for guiding said cutter means along a rectilinear path; and cutter guide positioning means extending in overlying relation with the article from the rectilinear edge thereof for selectively positioning said cutter guide means to guide said cutter means along a rectilinear path spaced from and substantially parallel to the rectilinear edge, when the article is supported and positioned by said platform means; said cutter guide positioning means including connecting means for adjustably connecting said cutter guide means with said platform means adjacent said shoulder means, to vary the distance between said rectilinear path and the rectilinear edge of the article in preselected increments, said connecting means comprising means forming a plurality of positioning holes and peg means upstanding from said platform means adjacent said shoulder means for engaging selected ones of said holes.
Claim 2
Dependent Claim
181 words
Apparatus for cutting a flat article having a rectilinear edge comprising: cutter means for making a cut in the article; platform means for supporting the article, said platform means including rectilinear shoulder means upstanding therefrom for engaging and positioning the rectilinear edge of the article; cutter guide means for guiding said cutter means along a rectilinear path; and cutter guide positioning means extending in overlying relation with the article from the rectilinear edge thereof for selectively positioning said cutter guide means to guide said cutter means along a rectilinear path spaced from and substantially parallel to the rectilinear edge, when the article is supported and positioned by said platform means; said cutter guide positioning means including connecting means for adjustably connecting said cutter guide means with said platform means adjacent said shoulder means, to vary the distance between said rectilinear path and the rectilinear edge of the article in preselected increments, said connecting means comprising means forming a plurality of positioning holes and peg means upstanding from said platform means adjacent said shoulder means for engaging selected ones of said holes.
Claim 3
Dependent Claim
43 words
The apparatus of claim 1, wherein the holes are arranged in two series, each including holes alternately displaced on each side of a line extending perpendicular to said shoulder means in order to lessen the possibility of improperly positioning said cutter guide means.
Claim 4
Dependent Claim
22 words
The apparatus of claim 1, wherein said connecting means includes two spaced apart parallel arms, each including at least one positioning hole.
Claim 5
Dependent Claim
202 words
Apparatus for cutting a flat article having a rectlilinear edge comprising: cutter means for making a cut in the article; platform means for supporting the article, said platform means including rectilinear shoulder means upstanding therefrom for engaging and positioning the rectilinear edge of the article; cutter guide means for guiding said cutter means along a rectilinear path; and cutter guide positioning means extending in overlying relation with the article from the rectilinear edge thereof for selectively positioning said cutter guide means to guide said cutter means along a rectilinear path spaced from and substantially parallel to the rectilinear edge, when the article is supported and positioned by said platform means, said cutter guide positioning means including connecting means for adjustably connecting said cutter guide means with said platform means at a plurality of spaced locations along the length thereof adjacent said shoulder means to selectively vary the distance between said rectilinear path and the rectilinear edge of the article while insuring parallelism therebetween, said connecting means comprising means forming a plurality of positioning holes and peg means at each of said spaced locations, said peg means upstanding from said platform means adjacent said shoulder means for engaging selected ones of said holes.
Claim 6
Dependent Claim
202 words
Apparatus for cutting a flat article having a rectlilinear edge comprising: cutter means for making a cut in the article; platform means for supporting the article, said platform means including rectilinear shoulder means upstanding therefrom for engaging and positioning the rectilinear edge of the article; cutter guide means for guiding said cutter means along a rectilinear path; and cutter guide positioning means extending in overlying relation with the article from the rectilinear edge thereof for selectively positioning said cutter guide means to guide said cutter means along a rectilinear path spaced from and substantially parallel to the rectilinear edge, when the article is supported and positioned by said platform means, said cutter guide positioning means including connecting means for adjustably connecting said cutter guide means with said platform means at a plurality of spaced locations along the length thereof adjacent said shoulder means to selectively vary the distance between said rectilinear path and the rectilinear edge of the article while insuring parallelism therebetween, said connecting means comprising means forming a plurality of positioning holes and peg means at each of said spaced locations, said peg means upstanding from said platform means adjacent said shoulder means for engaging selected ones of said holes.
