Interlocking checker tile

摘要

Disclosed are checker tiles for regenerative heating stoves, each tile having the general shape of a parallelepiped, the preferred tile being square in plan, having apertures extending through the tiles and having complementary ribs and grooves extending on the ends of the tile between adjacent apertures to interlock the tiles with contiguous end-abutting tiles and prevent substantial lateral movement thereof when the tiles are arranged in stacked overlapping relation.
