ABSTRACT:
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.
Also disclosed is supporting means for checker tiles providing for low friction and preferential sliding of horizontal contacting surfaces to permit lateral relative movement between the lowermost course of tiles and supporting means that avoids damage to tiles on dimensional changes of the tiles or supporting means due to temperature changes in operation of the stove.
