Abstract: A safety device for use on powered woodworking tools such as table saws, radial arm saws, and jointer-planers, to push a workpiece through an area of engagement with a rotating blade of such a tool. The safety device includes a guide bar mounted on the power tool in a position where it does not interfere with normal use of the tool, and a workpiece-engaging plate of the safety device is movable along the guide bar by use of a handle located spaced apart from the blade so that the operator of the tool does not have to bring his hands close to the blade while the workpiece-engaging plate moves along a rip fence or guide wall of the tool to advance a workpiece. The workpiece-engaging plate is mounted adjustably on a slide body which can be pivoted about the guide bar as well as being slid along it.
