Abstract
Abstract A sheet material cutting device which includes a cutting board and a guide extending over the top of the board. A cutting block is mounted for sliding movement along the guide. The cutting block may include a base and a cutting blade normally biased away from the board, but adapted to be pivoted toward the board into engagement with a sheet positioned thereon. Where bevel cuts are desired, the cutting blade is at a non-perpendicular angle to the cutting board and the cutting blade is pivoted into angular engagement with the sheet. A scale is mounted for movement with the cutting block. The scale has a reference marking at the point where the cutting blade engages a sheet and extends from the reference point in at least one direction. The scale may be utilized to easily and accurately determine points at which the beginning and end of a cut occur.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
152 words
A cutting block for a sheet material cutting device, said device having a cutting board and a guide extending over the top of the board comprising: a base mounted for sliding movement along said guide; a cutting means pivotally supported on said base, said cutting means being normally biased away from said board, but being adapted for pivoting toward the board to engage a sheet positioned thereon; and a scale mounted for movement with said base, said scale having a reference marking at the point where said cutting means engages a sheet when pivoted and extending from said reference marking in at least one direction, said scale being graduated in units of linear measurement starting at said reference marking and being adapted to be directly indexed on an edge of said sheet material, whereby the points at which the beginning and end of a cut occur may be easily and accurately observed.
Claim 2
Dependent Claim
152 words
A cutting block for a sheet material cutting device, said device having a cutting board and a guide extending over the top of the board comprising: a base mounted for sliding movement along said guide; a cutting means pivotally supported on said base, said cutting means being normally biased away from said board, but being adapted for pivoting toward the board to engage a sheet positioned thereon; and a scale mounted for movement with said base, said scale having a reference marking at the point where said cutting means engages a sheet when pivoted and extending from said reference marking in at least one direction, said scale being graduated in units of linear measurement starting at said reference marking and being adapted to be directly indexed on an edge of said sheet material, whereby the points at which the beginning and end of a cut occur may be easily and accurately observed.
Claim 3
Dependent Claim
46 words
A cutting block of the type described in claim 1 wherein said cutting means includes a blade holder having a blade supporting face, means for clamping a cutting blade to said face, and a part to which pressure may be applied to pivot said cutting means.
Claim 4
Dependent Claim
51 words
A cutting block of the type described in claim 2 wherein said part to which pressure may be applied is positioned so that pressure applied to said part after the cutting means has engaged a sheet is operative to move the block along the guide in the direction of the pressure.
Claim 5
Dependent Claim
33 words
A cutTing block of the type described in claim 2 wherein said blade supporting face is at a non-perpendicular angle to said board whereby said cutting means makes bevel cuts in a sheet.
Claim 6
Dependent Claim
44 words
A cutting block of the type described in claim 4 wherein the pivoting of said cutting means causes it to engage a sheet at an angle; and wherein the angle at which said cutting means engages a sheet is equal to said non-perpendicular angle.
Claim 7
Dependent Claim
16 words
A cutting block of the type described in claim 5 wherein said non-perpendicular angle is 60*.
Claim 8
Dependent Claim
52 words
A cutting block of the type described in claim 2 wherein said scale is positioned parallel to said blade supporting face and is spaced therefrom by a distance slightly greater than the thickness of a cutting blade, whereby a blade positioned between the face and the scale is held against lateral movement.
Claim 9
Dependent Claim
32 words
A cutting block of the type described in claim 1 wherein said cutting means is supported at a non-perpendicular angle to said board whereby bevel cuts may be made in a sheet.
Claim 10
Dependent Claim
21 words
A cutting block of the type described in claim 1 wherein said scale extends in both directions from said reference marking.
Claim 11
Dependent Claim
42 words
A cutting block of the type described in claim 9 wherein there are a pair of said reference markings, one for each direction in which said scale extends, said reference markings being slightly separated to compensate for the width of the blade.
Claim 12
Dependent Claim
35 words
A cutting block of the type described in claim 1 including at least one scallop in said scale in the area of said reference marking to provide maximum visibility of the blade in that area.
