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.
Claims13
A safety device for use in advancing a workpiece into cutting engagement with a blade of a power tool including a table having a top surface and a workpiece guide including a workpiece-guiding surface extending above said top surface, the safety device comprising:
- (a) a guide bar;
- (b) a slide body slidably mounted on said guide bar, said slide body being rotatable about an axis parallel with said guide bar, between a workpiece-advancing position and a retraction position, said slide body including a mating surface extending parallel with said guide bar;
- (c) a workpiece-engaging member fastened to said slide body in contact with said mating surface;
- and
- (d) a pair of mounting devices engaging said guide bar and supporting said guide bar in a predetermined position.
In combination with a power tool including a table having a top surface and a workpiece guide extending above said top surface, said workpiece guide including a workpiece-guiding surface, a safety device for use in advancing a workpiece into cutting engagement with a blade of said power tool, the safety device comprising:
- (a) a guide bar having a longitudinal axis;
- (b) a slide body mounted on said guide bar and slidable therealong, said slide body being rotatable through an angle about said longitudinal axis of said guide bar, between a workpiece-advancing position and a retraction position, said slide body including a mating surface extending parallel with said guide bar;
- (c) a workpiece-engaging member fastened to said slide body in contact with said mating surface;
- and
- (d) a pair of mounting devices engaging said guide bar and supporting said guide bar in a predetermined position with respect to said workpiece guide.
