FURNCE WALL.

Application. led December 10, 1921. Serial No. 521,378.

To all 'whom it may concern.'

Be it known that I, MICHAEL LIPTAK, a citizen of the United States, residin at St. Paul, in the county of Ramsey and tate of Minnesota, have invented certain new and useful Improvements in Furnace Walls; and I do hereby declare the lfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

My present invention relates to the construction of furnace walls and is in the nature of a modification of or improvement on the construction disclosed and claimed in my co-pending application filed of even date herewith under Serial Number 521,377

In' the wall of my said co-pending application and in the present wall, the complete wall structure is made up of a permanent outer masony wall and a replaceable inner masonry wall, and said inner wall includes horizontally aligned shelfforming tiles, certain of which are partly imbedded in and anchored to the permanent outer wall.

The present invention is directed to certain novel features which will be fully described in connection with the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a fragmentary-perspective with some parts removed, showing a furnace wall designed in accordance with my present invention;

Fig. 2 is a fragmentary plan view of the wall shown in Fig. 1, some of the tiles o f the outer wall and shelf-forming tiles of the inner wall being removed;

Fig. 3 is a fragmentary elevation looking at the inner face of the complete wall structure;

Fig. 4f is a vertical section taken on the line 4--4 of Fig. 2;

Fig. 5 is a fragmentary elevation lookmg at the outer face of the complete wall;

Fig. 6 is a perspective of one of the main shelf-forming tiles;

Fig. 7 is a perspective of one of the sup'- plemental shelf-forming tiles;

Fig. 8 is a perspective of one of the tiles of the permanent outer wall structure;

Fig. 9 is a view corresponding to Fig. 2

but illustrating a slightly modified construction;

Fig. 10 is a vertical section taken on the line 10-10 of Fig. 9;

Fig. 11 is a perspective showing two adjacent tiles of the permanent outer wall, the same being slightly separated; and

'Fig 12 is a perspective showing one of the supplemental shelf-forming tiles of the structure illustrated in Figs. 9 andl 10.

The outer or permanent masonry wall is made up chiefly of ordinary bricks 10 laid in mortar in the customary way; but to provide for shelves to support the horizontal sections of the replaceable inner wall, said outer masonry wall, on certain horizontal lines, is provided with tile courses made up of approximately L-shaped tiles 12 that are laid alternately so that said L- shaped tiles are positioned back to back and end to end, thereby leaving in the tile layer rectangular seats or openings, into which the'main shelf-forming tiles are adapted to be inserted.

rI`he main shelf-forming tiles 11 constitute elements of the replaceable inner wall and they are, as above indicated, partly imbedded in and anchored to the permanent outer wall by insertion of their outer portions into the rectangular seats of the tire layers of said outer wall. Said tiles project to the inner surface of the inner wall to adapt the shelf-forming tiles 11 to support the supplemental shelf tiles 14, said tiles 11 at their parallel edges are rabbeted at 15 and thev edges of the supplemental tiles 14 are reversely rabbeted so that the latter will be supported by and horizontally iiush with the former.

The main body portion of the replaceable inner wall is made up of high temperature or tire brick 16 laid in superimposed horizontal courses on the shelf-forming tiles, filling the spaces between the vertically spaced horizontal shelves, as best `shown in Fig. 1.

From the above, it is evident that the complete furnace wall, including what is herein particularly designated as the permanent outer masonry wall and the replaceable inner fire wall, may be made up entirely of masonry work.

When any portion of the inner fire wall has been burned away to a point where it re- Vquires replacement, the defective lire bricks or tiles may be removed or replaced without disturbing or taking down the permanent outer wall. If only a few of the bricks 16 have been burned away, they may be removed and replaced without disturbing the Shelf tiles. However, usually also some of I the shelf tiles will be burned and require re-v placement, and this may be readily -done as follows: The replacement of any of the supplemental shelf-forming blocks 14 is a very simple matter since it does not extend into the permanent outer wall. If one of the partly imbedded main shelf-forming tiles 11 requires replacement, it may be easily pulled or knocked out of position', thereby making 'possible the replacement thereof by a new tile of the same character. The outer or permanent wall is not weakened or disturbed to any appreciable extent by the above o eration because, at intervals between tllie seats formed for the main shelf-forming tiles, said outer wall is left intact or vwith complete vertical supports.

The construction lllustrated in Figs. 9 to f 12, inclusive, is like that already described,

except that the outer wall tiles 12, at the under surface of their long abutting edges, are formed with rabbets 12a that afford a channel that leads to a centrally located channel 14El formed in the bottom of the adjacent supplemental shelf-forming tile 14. Ihese groove-forming rabbets 12a and channels 14a permit stilil metal bars 17 to-'be inserted through the permanent outer wall and v under the supplemental shelf-forming tiles 14, as shown in Figs. 9 and 10.

Obviously, the metal bars 17 thus applied supplemental shelf-forming tiles while making rev pairs. Said bars 17 may be removed from the wall underordinary conditions or they may be left in place. Y

It should be noted .that in 'the wall deforded for the outer ends scribed the tile courses of the permanent outer wall are made up of tiles, all of one kind, towit: of L-shaped tiles, laid in the alternated positions described, with their transverse long portions afforded complete wall-forming elements between the seats afof the mainshelfforming tiles 11. This construction is therefore not only very elective, but the tiles may be cheaplymade' and rapidly and accurately laid.

W'hat I claim is: l

1. A wall structure comprising a perma-` nent masonry outer wall and a replaceable masonry inner wall, said outer wall having vertically spaced horizontal tile layers made up of alternately reversed L-shaped tiles, and said inner wall including shelf-forming tiles partly imbedded in seats formed in said outer wall by said L-shaped tiles.

2. The structure defined in claim 1 in which su plemental shelf-forming tiles are supported) by said main shelf-forming tiles and extend only within the outer wall space.

3. The structure defined in claim 2 in which said shelf-forming tiles are provided with lapped rabbeted edges and are thereby made horizontally flush.

4. The structure defined in claim 1 in further combination with metal bars insertable through grooves in said wall structure, from the outer-side of the wall structure to positions underlying and supporting certain of the shelf-forming tiles.

5. The structure delined in claim 2 in which said L-shaped tiles at their long abutting edges are formed with rabbets and said supplemental tiles are formed with channels, and in further combination with metal bars insertable through said rabbets and channels to support said supplemental tiles from the outer wall structure.

In testimony whereof I ax my signature.

' MICHAEL LIP'IAK.
