Abstract
Abstract A cutting guide and board assembly preferably includes a rectangular board with side plates fastened along each shorter side and an elongated flexible guide element extending over the board''s upper surface parallel to the longer sides of the board. The guide element is positioned about centrally of the board and each of its ends are fastened to a side plate so that the guide element bridges the plates leaving a space between the upper surface of the board and the bottom of the element. The upper board surface has two grooves, one beveled at about 45 degrees and the other with straight sides extending normal to the board. The guide element has a vertical surface and an angled edge along its opposite longitudinal sides in alignment with the straight and beveled grooves respectively so that a mat can be held down and cut using the guide element to correctly position a knife blade.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
239 words
A cutting guide and board assembly comprising a grooved board and a straight guide element, said element being secured to opposite sides of said board and extending across the upper surface of smae, said board having a vertical groove and a beveled groove in the upper surface of said board, said grooves extending parallel to one another in spaced apart relationship, said guide element being an elongated angled flexible bar of single-piece construction having a beveled edge and a straight edge on the opposite longitudinal sides of said bar and in registered alignment with said beveled groove and said vertical groove respectively, said straight edge being an upwardly bent portion having an upright vertical surface that extends normal to the upper surface of said board, said beveled edge including an angular projection that comprises an upwardly bent angled portion followed by a downwardly bent angled portion that extends upwardly with respect to said board, said downwardly bent angled portion providing an angled side that affords a guide for a cutting member, squaring means at each of said opposite sides of the board and said guide bar being secured to the opposite, sides to bridge said upper surface leaving a space between said surface and the bottom of said bar, whereby sheet and board material can be inserted in said space below said bar and manually cut using said grooves and the edges of said longitudinal sides as cooperating guides.
Claim 2
Dependent Claim
239 words
A cutting guide and board assembly comprising a grooved board and a straight guide element, said element being secured to opposite sides of said board and extending across the upper surface of smae, said board having a vertical groove and a beveled groove in the upper surface of said board, said grooves extending parallel to one another in spaced apart relationship, said guide element being an elongated angled flexible bar of single-piece construction having a beveled edge and a straight edge on the opposite longitudinal sides of said bar and in registered alignment with said beveled groove and said vertical groove respectively, said straight edge being an upwardly bent portion having an upright vertical surface that extends normal to the upper surface of said board, said beveled edge including an angular projection that comprises an upwardly bent angled portion followed by a downwardly bent angled portion that extends upwardly with respect to said board, said downwardly bent angled portion providing an angled side that affords a guide for a cutting member, squaring means at each of said opposite sides of the board and said guide bar being secured to the opposite, sides to bridge said upper surface leaving a space between said surface and the bottom of said bar, whereby sheet and board material can be inserted in said space below said bar and manually cut using said grooves and the edges of said longitudinal sides as cooperating guides.
Claim 3
Dependent Claim
30 words
The assembly of claim 1, wherein said beveled edge and said beveled groove have aligned sides that are angled about 45* with respect to said upper surface of the board.
Claim 4
Dependent Claim
17 words
The assembly of claim 1, wherein said beveled edge and said verticAl surface each have measuring indicia.
Claim 5
Dependent Claim
40 words
The assembly of claim 1, wherein the upper surface of said board has aligned stripes that are spaced apart from one another, said stripes being parallel to said grooves to afford scales across the entire upper surface of said board.
Claim 6
Dependent Claim
43 words
The assembly of claim 1, wherein said board is rectangular when viewed in plan, the shorter sides of said board having scaled squaring means extending adjacent the peripheries of said sides, the ends of said guide bar being secured to said squaring means.
Claim 7
Dependent Claim
37 words
The assembly of claim 5, wherein said squaring means includes a flat plate member with measuring indicia that extends along the edges of each said shorter side to afford an abutting surface for the material being worked.
Claim 8
Dependent Claim
26 words
The assembly of claim 6, wherein said guide bar is flexible whereby the material being worked is held by said bar when the latter is depressed.
