  • Patent number: 9707694
    Abstract: A push block for a woodworking tool includes a heel member at an end of the push block and the heel member is passively actuatable to an extended position to engage a trailing end surface of a work piece to advance the work piece by a working element. The push block also includes a wall member along a first side of the push block to serve as a barrier between a cutting element and an operator's hand. In addition, the push block includes a handle that is disposed obliquely relative to first and second sides and a longitudinal axis of the push block.

  • Publication number: 20150290832
    Abstract: A heel member for a push block used with a woodworking apparatus comprises a side surface that is disposed substantially perpendicular to a bottom surface of the push block and is spaced apart from and end of the push block. A heel position adjustment mechanism is operatively connected to the heel member to adjust the heel member and a bottom edge of the heel member to multiple selected positions relative to a bottom surface of the push block. The heel member may have an inclined surface abutting an incline surface at the end of the push block and female and male guides along both inclined surfaces in mating relationship.

  • Patent number: 9003671
    Abstract: A tapering jig for a woodworking apparatus that includes a top and bottom plate that pivot relative to one another to set a cutting angle of a work piece. The jig further includes at least one scale of one or more markings that represent a cutting angle and/or a “rise and run” measurement. In addition, a dial is positioned relative to the at least one scale to identify and set the cutting angle and/or “rise/run” measurement. The dial includes a plurality of pointers and a plurality of pins and each pin is associated with a respective pointer. Consecutive pins are offset incrementally from the respective pointers so that each pointer can be inserted in the same recess adjacent to the scale to incrementally adjust the cut angle and/or “rise/run” measurement.

  • Patent number: 7997313
    Abstract: A guide bar assembly (10) for use in a T-slot (20) of a woodworking table (22). The assembly includes a top member (12) slidably disposed on a bottom member (14). The top and bottom members include cooperating pairs of wedge shapes (24) that cause a change in width (W) of the assembly in response to relative longitudinal (L) movement between the top and bottom members. Contacting angled side surfaces (30, 32) of the male and female wedge members (26, 28) provide area contact between the top and bottom members that functions to maintain the top and bottom members parallel during tightening of the fasteners (34) used to lock the assembly at a desired width.

  • Patent number: 7040206
    Abstract: An adjustable pushing apparatus (50) for safely moving a work piece (22) past a cutting tool (16). The apparatus includes a body (52), a first leg (56), a second leg (58) and a moveable center leg (60) defining a leg side surface (74) and two adjustable-width tunnels (62, 64) through which a cutting tool may pass. A handle (54) is moveable along a top surface (82) of the body to provide a balance of forces on both the inside cut portion (24) and the outside cut portion (26) of the work piece. Non-slip work piece-contacting surfaces (76) provide positive engagement with the work piece. A spacer (84) may be attached to either leg at a plurality of vertical heights to balance the apparatus when the work piece is too narrow to make contact with a work piece-contacting surface on both side of the cut line (C). A dust shield (120) attaches to the handle keyways at two alternative locations. A tapering device (144) attaches to the apparatus for making taper cuts.
