Abstract
Abstract A cutting guide for urging work material against the rip fence of a circular saw, joiner, shaper, or the like, includes a mounting block which is clamped to the work table with the mounting block provided with two spring steel bands arranged in loops and mounted in overlapping relation to each other on the mounting block. The spring bands are angled to provide a lead-in in the direction of work feed.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
113 words
A cutting guide for urging work material against a cutting fence comprising a mounting block having a side, a pair of spring bands, means for mounting the ends of said spring bands together and independently on said mounting block at a point remote from said loop ends to form closed loops and to provide a loop deflection axis to afford both deflection of the axes of said loops and compression of said loops upon pressure from a work piece with said loops being mounted in overlapping relationship to provide lateral biasing forces at spaced points on a work piece with less pressure being required to cause deflection of said loops than compression thereof.
Claim 2
Dependent Claim
113 words

Claim 3
Dependent Claim
37 words
A cutting guide in accordance with claim 1 wherein said mounting means for said bands comprises apertures in ends of said bands and fasteners extending through said apertures to secure said bands to said mounting block side.
Claim 4
Dependent Claim
21 words
The device of claim 1 including a chip shield and means for adjustably mounting said chip shield on said mounting block.
Claim 5
Dependent Claim
22 words
The device of claim 1 wherein the longitudinal axes of the loops is at an angle relative to the cutting feed path.
