ABSTRACT:
A tuckstone assembly (14) for an industrial type furnace (10) fills a space between a wall of the furnace and a supporting member (19) that supports the furnace superstructure. The tuckstone assembly (14) has a support block (26) having a sloped upper surface (27) and a nose block (37) having a mating sloped lower surface (38). The longitudinal profile of the tuckstone is reduced for insertion in the space of the furnace wall by sliding the nose block forwardly, and the enlarged nose portion (42) is made to cover the support plate (19) by sliding the nose block (37) back to where the ends of the support block and the nose block substantially coincide.
