Abstract
Abstract A saw guide for guiding a hand powered saw to make a straight cut at any predetermined angle, the device including a solid guide bar and a saw base pad, to slidably fit over the guide bar, comprised of a different material than the guide bar itself, with the material selected to reduce sliding friction between the guide bar and the base pad.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
A tool guide comprising in combination, a saw guide bar which is solid and rectangular in cross-section for extension across a work piece, said bar having a forward end and a rearward end, an anchor plate attached near said rearward end of said guide bar to allow pivotal movement of said guide bar with respect to said plate; clamping means on said plate to clamp said plate to a work piece, and to releaseably clamp said guide bar to predetermined fixed positions with respect to said anchor plate; and a tool base pad having a groove therein adapted to slidably fit over said guide bar for lengthwise sliding along said bar and which can be lifted upwardly and off of said bar, said base pad being constructed of a material different than said guide bar and selected to reduce sliding friction between said guide bar and said base pad, and pressure sensitive adhesive strip means on said pad to attach a powered hand tool thereto without altering the structural elements of such hand tool.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
19 words
The saw guide of claim 1 wherein said guide bar is an elongated solid bar of cold, rolled steel.
Claim 4
Dependent Claim
30 words
The saw guide of claim 1 wherein said base pad is a solid, polymeric hardened, thermosetting plastic material which reduces sliding friction between said base pad and said guide bar.

Claim 6
Dependent Claim
24 words
The saw guide of claim 1 wherein said anchor plate has a protractor index marked thereon to determine the angle of said guide bar.
