Abstract:
1. A coping apparatus facilitating a left or right, straight, or coped cut through a molding with adjustability for a wall-to-ceiling angle, a wall-to-floor angle, a wall-to-wall angle, and/or a backcut angle comprising: (a) a rotatable holder assembly including a circular-shaped table disposed within a circular-shaped opening along a vertical element of an L-shaped base element, wherein said circular-shaped table and said vertical element are in a coplanar arrangement, said circular-shaped table rotatable within and restrained from axial movement in said circular-shaped opening, said circular-shaped table including at least one opening there through and a two-axis positioning system with a carriage movable along a direction parallel to said circular-shaped table on a guide attached to said circular-shaped table a movable member of said two-axis positioning system passing through said carriage and further passing through said at least one opening in a direction substantially perpendicular to said circular-shaped table, said circular-shaped table lockable to said vertical element so as to allow for adjustment to said left or right, straight, or coped cut and said wall-to-wall angle via adjustment of said guide with respect to a horizontal wall of a rotatable platform on which said molding is supportable; (b) a rotatable cutter assembly located on a pivot at one end of said movable member, said rotatable cutter assembly rotatable about a pivot axis parallel to said movable member and lockable with respect to said rotatable holder assembly, said at least one stylus attached to and extending from said rotatable cutter assembly, said rotatable cutter assembly capable of holding a cutting device substantially parallel to said rotatable holder assembly adjacent to said at least one stylus so that a cut is substantially perpendicular or at said backcut angle to said horizontal wall, said rotatable cutter assembly being linearly movable along a direction perpendicular to said rotatable holder assembly as permitted by said two-axis positioning system and moveable parallel to said rotatable holder assembly as permitted by an angular orientation of said guide, said rotatable cutter assembly movable so that said at least one stylus traces a profile of said molding and said cutting device cuts said molding along a straight line or a complement of said profile; and (c) said rotatable platform including a horizontal wall and a vertical wall in a perpendicular arrangement, said molding positionable on said horizontal wall next to said vertical wall and securable thereto, said horizontal wall perpendicular to said rotatable holder assembly and said vertical wall substantially parallel to said rotatable holder assembly, said rotatable cutter assembly sufficiently moveable so as to completely cut said molding disposed along said horizontal wall and said vertical wall, said horizontal wall swivels about a pivot pin along a horizontal element of said L-shaped base element for adjustment to said wall-to-floor angle and said wall-to-ceiling angle cut by said cutting device, said rotatable platform lockable to said base element, said rotatable platform including a table clamp adjustably attached to said horizontal wall and at least one stationary pin extending therefrom, said table clamp presses said molding onto said stationary pin to prevent movement of said molding as it is cut, said horizontal element of said L-shaped base element attached to and supporting said rotatable holder assembly and said rotatable platform.
