Abstract

Abstract A guide formed with a guide face elongated parallel to a line of proposed cut, and provided with a squaring member projecting from said guide transversely to said face to engage a surface of a workpiece. A saw cut indicator projecting transversely to said guide face in the direction opposite from said squaring member, and terminating in a saw cut indicating edge predeterminedly spaced from and parallel to said guide face, said saw cut indicator being made of a material of some permanence, but readily cut by a saw blade, so that on an initial cut using a specific electric saw, the blade will permanently establish the saw cut indicator edge for that particular saw. Screws threadedly received in said squaring member and adjustable to establish angular divergency between said squaring member and the surface of a workpiece engaged thereby and consequently a corresponding divergency of a saw cut.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 132 words
A guide assembly for a held-held electric saw, including, a saw guide to surmount a workpiece to be cut, a rectilinear guide face elongated on said guide, a squaring element projecting in one direction from said guide transversely to said guide face to engage the surface of a workpiece and position said guide face for a desired cut, said squaring element including a first flange engageable with a surface of a workpiece, a second flange parallel to and spaced from said first flange, one or more screws threadedly received in said second flange for rotatable adjustment therein and having terminal engagement with the surface of a workpiece to establish angular divergency between said first flange and such surface of a workpiece, and said first flange being adapted to afford said terminal engagement.
