Abstract
An anti-kickback device is disclosed where the device includes a plurality of flexible members, and at least a compliant contact surface in contact with a moving workpiece, where the flexible members provide a biasing force against the workpiece and also resist or prevent kickback of the workpiece as it engages a tool such as a shaper, saw blade, etc. The configuration of the flexible members assures an opposing force to resist kickback.
Claims16
An anti-kickback device for biasing a workpiece on a machine having a work surface that guides the workpiece relative to a tool, said anti-kickback device comprising:
- a support frame having at least one slot therein for adjustable attachment relative to the work surface;
- and
- a plurality of elongated flexible members having a first end operatively connected to the support frame, and a free moving second end opposite the first end, said second end being suitable for sliding contact with the workpiece, wherein at least a portion of the second end of each flexible member comprises a deformable material and the deformable material is conformable to a non-planar workpiece surface in order to assure contact between said second end and the workpiece surface;
- where the second end of each of the plurality of elongated flexible members remain in conformable contact with said workpiece and provide a biasing force against the surface of the workpiece.
An anti-kickback device for applying a biasing force on a workpiece, said anti-kickback device comprising:
- a plurality of elongated flexible members, each of said flexible members having a first end operatively connected to a support, and a second end in contact with the workpiece, where the elongated flexible members deflect along their length in response to contact with the workpiece, and at least a portion of the second end of each of the plurality of elongated flexible member includes a material that deforms to conform to a non-planar shape of the workpiece and thereby remains in conformable contact with at least one surface of the workpiece to apply a biasing force to the workpiece.
An anti-kickback device for applying a biasing force on a workpiece, said anti-kickback device comprising:
- a plurality of elongated flexible members, each of said flexible members having a first end operatively connected to a support, and a second end in contact with the workpiece, wherein at least a portion of the second end of each of the plurality of elongated flexible member includes a material that remains in conformable contact with at least one surface of the workpiece to apply a biasing force to the workpiece, wherein the second end of each flexible member includes a roller and each roller includes a deformable material on at least an outer surface thereof.
