Patent ID: 6932608

Claim:
A model and die system, comprising: a working base having a flat upper surface; a first row of bores formed in said flat upper surface in closely spaced relation to a preselected edge of said working base; a second row of bores formed in said working base in parallel relation to said first row of bores, said first row of bores being spaced between said second row of bores and said preselected edge of said working base; at least one cast tooth adapted to releasably engage said working base; said at least one cast tooth having a first pin and a second pin depending therefrom; said first pin disposed within a preselected bore of said first row of bores and said second pin disposed within a preselected bore of said second row of bores; said at least one cast tooth positioned so that a leading surface of said at least one cast tooth is substantially flush with said preselected edge of said working base; an opposing top member having a flat lower surface; a plurality of mounting posts depending from said opposing top member; a cast tooth being mounted on each mounting post of said plurality of mounting posts; a plurality of sets of apertures formed in said flat lower surface, said plurality of sets of apertures being positioned in a single row of sets of apertures; each set of apertures including a plurality of apertures arranged in circumferentially spaced apart relation to one another; each of said mounting posts being fluted; a fluted mounting post associated with each set of apertures; each fluted mounting post being centered with respect to its associated set of apertures; each fluted mounting post depending from said flat lower surface of said opposing top member; each fluted post having four semicircular flutes, each of which is in registration with an associated aperture of said sets of apertures; each flute having a depth substantially equal to the radius of its associated aperture so that no part of the mounting post occludes any of its four associated apertures; interconnecting means for interconnecting said working base and said opposing top member; whereby a bite between said at least one cast tooth mounted to said working base and said at least one cast tooth mounted to said opposing top member is checked by bringing said opposing top member toward said working base until said cast teeth abut one another, said interconnecting means serving to maintain alignment between said working base and said opposing top member as said opposing top member is brought into registration with said working base.
