ABSTRACT:
A novel arrangement of pressure foot and drive therefor for providing a frictional clamping arrangement for holding a workpiece being cut by a router so as to prevent movement of the cutout portion of the workpiece in the last increment of the cut. The pinless pressure foot includes a ring-shaped friction member supported by a slide member adjacent one end of a spindle, circumscribing a cutting tool, for engaging the surface of the workpiece. A plurality of flexure members extend around the spindle, first ends of the flexure members being connected to the slide member. The drive is positioned adjacent the other end of the spindle and is movable axially relative thereto, the drive being connected to the other ends of the flexure members for moving the friction member into contact with the workpiece, the flexure members transmitting the axial force of the drive to the friction member to force the workpiece against a worktable for preventing movement thereof relative to the worktable during completion of the cut. The flexure members permit lateral movement of the friction member relative to the cutting tool during completion of the cut. A locking ring selectively prevents lateral movement of the friction member relative to the cutting tool.
