Abstract

Table saw accessories are shown that are easily mounted on a saw in use or a new saw for the purpose of reducing loads generated on the table saw blade during a sawing operation. Included are a spreading clip that can be pressed onto the leading edge portion of an existing kerf splitter to provide a quick and easy way to change the width of the kerf splitter; and an anti-friction add-on that is easily attached to an existing saw fence.

Claims

1. A table saw comprising:

a table;

a saw blade mounted on said table for producing a saw cut in a work piece;

a saw fence mounted on said table adjacent said saw blade, said saw fence having a work piece guiding surface;

means for reducing a total surface area of said work piece guiding surface, with said means for reducing the total surface area being provided with means for being demountably fastened to said saw fence;

a kerf mounted on said saw table and splitter having a leading edge for entering the saw cut in the work piece behind said saw blade; and

a spreading clip mounted on said kerf splitter leading edge, wherein said spreading clip has a thickness corresponding to a thickness of said saw blade.

2. The table saw of claim 1 wherein said means for reducing the total surface area includes:

a spacer plate having means for being demountably fastened to said work piece guiding surface;

vertical spacer bars connected to said spacer plate; and

horizontal guide rods connected to said vertical spacer bars, with said guide rods forming a second work piece guiding surface.
