Referringto'the-drawings, there are therein shown'variousv embodiments of my invention,.but it will, ofcourse, be understood that p' modifications may be made therein without Aleparting from the spirit of my invention,

and particularly, while typicaluses ofthe special formsA ofblocks for the purpose of fabricatingwalls and floorsof furnaces yare shown' in the drawings, .it willbe understoodV "hat the invention-is not limited to thesespe- I l lcifio wall constructions, but that-numerous other arrangementslof the special blocks in of ordinary shape, and of a width substan tially equalto the Vlength of a bri'clrofordinary shape.

The front portions of the blocks are preferably Voff-set so as to form a projection 25 on one side of each block, and a corresponding recess-26 on the other side thereof. The top and bottom surfaces -of the blocksv are also preferablyprovided with grooves 27, extending the full width of the block and forinving a mortar pocket' to effect a better seal between the blocks of. successive courses than would ordinarily. be provided by a straight ioint.l Y Y InV buildingthe furnace wall lwith blocks of the form above described, the same are preferablylaid up inconjunction with bricks 28of ordinary shape, as shown in Figs. 1 to 4 of; the drawings.

The blocks 18 and 19 are laid inalternate i. courses, andfthe'ton'guev portions 22 of said blocks extend into the outer Vportion of the wall between courses A of Vthe bricks 28, i said bricks.l 28being turned incertain of the Y courses thereof in order to permit said tongue portions'22 of theblocks18fandY19fto extend 1 "into thev portion of the walluformed'of the bondedtherewit 1 v Y It' will,f.offcourse, be-:understood that theJ bricks-28 of .ordinary 'shape maybe laid in anypreferred manner, as `to their respective bricks of'ordinaryf shape, and tobe eeetivelythatV where heavier walls are required additionalgthickness.,mayfbe provided by a suitable arrangement of said bricks 28.

. When the wall is laid up as above set forth,

vtherejwill'be provided horizontal passage- .ways"29, each formed by thejuxt'aposition of V.the horizontal recesses'21in-the'blocks 18 and 19, and certain faces-'of the bricks 28.l Like.- wise, therewill be provided a series of vertical-passageways 23 and',V 24 extending b,e-
