Abstract
A saw workpiece pushing device is operably attachable to a table saw and is utilized to facilitate the cutting of styrofoam or other similar material. The device includes an elongated pushing member which is attachable to the saw's miter gauge and which includes an U-shaped frame defining an opening through which the saw blade may pass without interference with the pushing member. Additionally, a side guide member is attachable to the saw's fence so as to permit an outward expansion of the styrofoam once the same has been cut. The side guide member is fixedly securable to the fence through the use of a C-clamp positionable between the fence and a slot cut in the guide member, while the pushing member may be fixedly secured by conventional means to the miter gauge. A safety extension is provided on one side of the U-shaped frame which operates to push the cut styrofoam off the table without the necessity of an operator using his hand near the saw blade to remove the styrofoam.
