FURNACE WALL.

Application sled August 3, 1925. serial No. 47,313.

'To r//Z lello/)1. z'l'nulg/ concern:

lie it known that l. .\lu'ii\il:i. Llr'ixii, a vcitizen ot' the United States, residing at tit. iaul, in the county ot Ramsey and State s of Minnesota, have invented certain new and useful improvements in Furnace vValls; and l do hereby declare the following to be a full, clair, and exact description ot the invention. such as will enable others` skilled te in the art to which it appertaius to make and use the same.

My present invention relates particularly to walls 'for furnaces and to that type ot furnace wall that comprises what may be 35 designated as a permanent wall aud a replaceable. wall, the two walls being' connected by blocks or elements that extend from the one wall into the other and are. so arranged that partial replacements ot' the inner wall may be, made without disturbing` undamaged portions thereot. Generally stated, the invention consists ol the novel devices, combinations ot devices and arrangement of parts hereinafter described and delined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several 4views.

Referring to the drawings: y

Fig. l is a fragmentary perspective showing a wall structure designed in accordance with my invention, some parts thereotl being removed;

Fig. f3 is a plan view of the wall shown in Fig. 1;

`Fig. 3 is a section taken approximately on the line Er-2i otl Fig'. 2, some parts being' removed and some parts heini; broken away;

Figs. si, 5 and (i are perspectives showingthe several specially constructed blocks used in the wall illustrated in Figs. 1, 2, and 3;

Figs. 7 and 8 are fragmentary plan views illustratimgT slightly moditied forms ot' the wall illustrated in Figs. 1, 2 and S;

Fig. 9 is a vertical section taken approximately on the line 9 9 ot Fig. S, some parts being removed and some parts being broken awa g Fie. 10 is a fragmentary perspective showing tlie type of structure illustrated in Figs. 1, 2 and 3 incorporated in a central or partition wall of the furnace, some parts being;` removed;

Fig'. 11 is al plan View of the wall shown in Fig. 10 5- sie Figs. 12 and 133 are perspectives showing in detail the specially constructed blocks used in the wall shown in Figs. 1t) and 11; and i Fig. 11 is a view corresponding to Fig.

11, but lillustrating,- a slightly modilied arrangement.

'.l`he pern'ianent wall, which in the wall structure illustrated in Figs. l, 2 and 3 is the outer wall, may be made up entirely ot lire brick or in part of tire brick and in part oil common brick, and it includes horizontal belts 15 ot' such bricks laid in the usual or any suitable way; and between theseA belts, said permanent wall includes specially constructed blocks 16 advisably made of tire clay. These blocks 1G are substantially L- shaped. butare formed on oblique lilies so that when they are laid together shown in Fie: 2, they extend obliqnely across the joints ot' the bricks ofthe belts 15 and leave oblique recesess that. are open at. the inner tace ot the permanent wall. This oblique arrangement, as will presently appear, is B0 highly important.. Moreover, it is important that the blocks '16 ot' the adjacent, vertically spaced courses are reversed so that they extend reversely oblique, that is, the one at an acute angle to the wall faced toward the lett and the, other at an acute angle toward the right.

The replaceable or inner wall is made up ot' horiz/,ontal belts 1T of tire brick, preferably laid as headers. and interposed horizontal layers ot specially constructed tire bricks or blocks 1S and 19. Thehloeks 18 and 19 are in the t'orm ot oblique parallelograms.that is, they liave parallel sides but the ends thereotl are oliliq'uely formed. The relatively long bricks or blocks 18, are adapted to be inserted into the oblique recesses formed between the oblique portions of the blocks 1G ot the outer wall, and when thus inserted. they project into the replaceable wall between the tire brick belts 17. As shown, said blocks 1S are ot' such length that they extend to the inner tace of the replaceable wall. The blocks or bricks 19 extendonly through the replaceable wall and till the 105 Spaces between the relatively long' blocks 18. r1`he blocks 18 ot the one row are extended obliquely in one direction and the blocks of the adjacent. verticali y spaced rows are oblique in the other direction. blocks and the bricks of the belts 17 will become, tusedtogether more or less under These lo the action of the intense heat from the furnace, and iyhen thus fused, will be very securely united so that the reversely oblique blocks 18 produce a sortof dove-tailed bond betvfeen the permanent andreplaceable Walls. The long blocks 18 are extended such distance into the recesses of the outer or permanent Wall that they Will support the brick `belts 17 and permit replacements of portions thereof Without disturbing overlying or adiacent belts. This fact is clearly illustrated in Fig. 1.

`When the blocks and bricks of the replaceable or inner Wall have been burned away to serious extent and require replacement.; the shortened blocks 18 may be removedl and new blocks substituted therefor; and to facilitate this removal, said blocks 18 are preferably provided with indentations 18 that are adapted to be engaged by a hammer a, as shown in Fig. 3. In Fig. 3, the dotted lines o indicate the portions of the blocks and bricks that have been burned away back to the broken lines c.

En the Wall described, the block elements 16 and 18 are the largest and heaviest in the Wall and even these are of such compara,- tively light weight that a mason can easily lift and place the same with one hand. iac-.oreoven these blocks and all of the blocks and bricks of the Wall are orn very simple construction and may be cheaply made and `will not be easily broken in handling. Hence, the block-forming elements may be manufactured at low cost and the Wall may built therefrom at a minimum of eX- pense. Moreover, the wall thus constructed may be of very high eiiciency, both as to durability and facility for repair.

The Wall illustrated in Fig. 7 is like that illustrated in Figs. 1, 2 and 3, except that the Lshaped blocks 16a are formed with longer outer Wings, so that the blocks 18 are placed in pairs Within the recesses formed in the permanent Wall by the said blocks 1th'.

The Wall illustrated in Figs. 8 and 9 is like that illustrated in Figs. 1, 2 and 3 except that the permanent Wall, instead of being made of tivo horizontal courses of bricks, is made of three horizontal courses 15, and the l--shaped blocks 161 are formed `with Wider outer Wings than the blocks 16, so that theblocks 19 may be used between the blocks 1S.

As already noted, Figs. lOto 14, inclusive,V

illustrate the invention incorporated in a central or partition Wall of a furnace and, hence, comprises a permanent central Wall and replaceable Walls on each side thereof. this Wall structure, as illustrated in Figs. 10 to 13, inclusive, the permanent or central well is made up of horizontal belts of brick 20, preferably ot the fire brick. and oblique laterally spaced blocks 21 also of lire clay or form are also oblique parallelograins. These blocks 28, when inserted into the recesses formed in the central Wall between the spacing blocks 21, meet at the central portion of the' center Wall with their outer oblique ends flush with the exposed surfaces of the respective replaceable Walls. T he said -blocks 23, when applied as described and shown in the drawings; will support the brick belts 22 so that they may be replaced in Whole or in art Without disturbing overlying or under ying belts. To facilitate removal of the blocks 23 that have been burned away, they are shown as provided with indentations 23. To fill the spaces in the rcplaccable walls left between the blocks 23, shorter blocks 2 are provided; and these blocks 21 in form are also oblique parallelograms and they should be made ot tire clay or tile.

The Wall shown in Fig. 14 is like that illustrated in Figs. 10 and 13, except that the long blocks 28 are located in pairs and the spacing blocks 21 are spaced farther apart, so as to receive the said pairs of blocks between them. Obviously, this center or partition ivall structure has all the advantages enumerated or which are found iu the outside Wall structure illustrated in Figs. 1, 2 and 3.

The scheme above disclosed is capable of modification Within the broad scope of the invention. The blocks or bricks in the form of oblique parallelograms are desirable because they give a smooth surface to the inner face of the replaceable Wall, but rectangular bricks or blocks having square corneis out obliquclvxy exposed to the Wall may be used with this slight disadvantage, however, that it' they extended to the inner surface ot the wall` they would produce a somewhat i1'- regular surface. Rectangular blocks or bricks such as just noted may be found for sale on the market carried in stock by most brick manufacturing concerns.

It is further important to note that the blocks 18, 19, 21, 23 and 24 are alike at both ends and hence are reversible end for end so if one end happens to be slightly broken or notched in shipment or handling. the had end can be placed inward and the better or more perfect end outward. lilforcover, the blocks are of suoli form that they are not likely to be broken in shipment.
