Abstract:
1. An insert for a table saw, comprising: (a) a planar member that is adapted to fit into an elongated recess provided in a top surface of said table saw; (b) an enlarged opening that is provided through said planar member and which is adapted to allow a portion of a table saw blade to extend from said table saw to a position that is above said top surface; (c) a pair of parallel, spaced-apart rails that extend along a longitudinal length of the enlarged opening from a distal end to a front of said planar member; (d) wherein a cross-section of said enlarged opening that also passes through said pair of parallel spaced-apart rails includes a T-shape, and (e) locking means adapted for securing said insert in said elongated recess, wherein said locking means includes at least one cam that is adapted to pivot about an axis that is perpendicular to said planar member, and wherein when said at least one cam is pivoted about said axis, said cam is adapted to bear against a portion of said elongated recess sufficient to place said insert under tension, and wherein said cam is adapted to pivot about said axis when said insert is disposed fully in said elongated recess; and (f) including means adapted for preventing two halves of a board that is being cut from being urged toward each other an amount sufficient to pinch said saw blade, and wherein said means adapted for preventing two halves of a board includes means for disposing a splitter post behind said blade and in line with a center of a plane of said blade sufficient to allow said splitter post to enter into a kerf of a cut produced by said blade in said board, and including a sliding member that is disposed in a sliding member recess that is provided in said insert and wherein a top surface of said sliding member is not disposed above an upper surface of said insert and wherein said sliding member is adapted to be urged from side to side in a direction that is perpendicular with respect to said plane of said blade and including means for securing said sliding member in a desired location in said recess and wherein said splitter post is attached to said sliding member.
