MEKLER MEANS PREVENTING PASSAGE OF GAS THROUGH REFRACTO RY WALLS Filed July 23, 1930 Fatented Aug. 28, 1934 MEANS PREVENTING PASSAGE F GAS THBOUGH REFRACTORY WALLS Lev A. fielder, Chicago, 111., assignor to Universal Oil Products Company, Chicago, 111., a corporation of South Dakota Application July 23, 193., Serial No. 470,203 6 Claim. (UL 72-101) This invention relates to a means and method of" preventing the passage of gas into or out of a furnace or the like through the refractory lining thereof, and refers specifically to a method of so forming and so disposing the blocks, comprising the lining; with respect to each other as to leave spaces at a portion of the joining surfaces of adjacent blocks which may be filled with a sealing or The utility, objects and advantages of my invention will be apparent from the accompanying drawing and the following detailed description.

In the drawing, Figure 1 is a fragmentary elevational view of a portion of a furnace roof or ceiling wherein my invention is utilized;

Figure 3 is a sectional elevational view of a suspended block for furnace wall constructions embodying nrv invention;

Figure 4 is a front elevational view of the wall shown in Fig. 3;

Figure 5 is a sectional .view taken on the line 55 of Fig. 3; and

Figure 6 is a detail perspective of a refractory block which may be utilized in the construction of a furnace wall.

Referring in detail to the drawing, 1 indicates a furnace roof or ceiling which may be constructed of concrete or the like. One flange of each of a plurality of beams 2 may be imbedded in the roof 1. The beams 2 may take the form of l-beams, channel irons, or any other desirable beam section. In the construction of furnace roofs or ceilings the supporting roof is usually insulated from the secondary or insulating re- I iractory roof, said insulation being accomplished by spacing the refractory roof from the supportingroof. Bythismeansanairspace3maybe provided between the supporting roof 1 and the refractories.

It is common practice in the furnace art to suspend the refractory blocks or tile from the supporting roof 1 usually'by attaching each row of blocks to the projecting end of an I-beam.

In my invention, I may suspend a plurality of blocks 4 from the supporting ceiling 1 by providing apertures 5 in the upper portion of the block 4, into which the lower flange of the downwardly projecting beam 2 is adapted to be positioned. It is to be understood of course, that my invention'is not specifically directed to any pmticular means of suspending the refractory root from a supporting roof, since the inventive concept contemplates any of the usual or conventional means of suspension.

As a feature of my invention, I may provide a refractory block 4 having one portion thereof 6 offset, both longitudinally and transversely, to form staggered longitudinal shoulders '7 and 8 and staggered'transverse shoulders 9 and 10. By the provision of a block of this shape the transverse joints between adjacent blocks are broken, as shownbest at 11 in Fig. 1. The provision of a broken joint of this type in itself tends to prevent the passage of furnace gases from the combustion chamber of the furnace to the air space 3, and in addition, likewise prevents the passage of air from the space 3 to the combustion chamber. To further impede the progress of gases passing from the combustion chamber to the air space 3, or vice versa, I may provide a packing 12 of asuitable material such as asbestos base cements, infusorial earth, or the like, in the transverse apertures formed between the upper longitudinal shoulder 7 of one block, the lower longitudinal shoulder 8 of an adjacent block, and the sides which form the joint 11.

In addition to breaking the transverse joints formed between the ends of adjacent blocks 4, the longitudinal joints may also be broken as shown best at 13 in Fig. 2, and by the provision of the staggered shoulders Q and 10 longitudinal apertures are provided which may be filled with a sealing material- 14 similar to the material 12. In this manner the four joining edges of each of the blocks are provided with a seal 12 and 14 which prevents any possibility of gases passing through the junctures of adjacent blocks.

- The feature of my invention of sealing junctures of adjacent blocks may also be applied to a suspended wall construction. By referring particularly to Figs. 3, 4, 5 and 6, 15 indicates a 811i?- porting wall constructed of a material similar to roof 1. Brackets 16 may be fastened to said wallhymeansofbolts 17 ortheliketheshanhs of which are adapted to be imbedded in said wall. Oneendoi'thebracketsifirnayterminateina hook-like member 18 which may be adapted to support the refractory block 19; said block being provided with a projection 20 adapted to engage the member 18.

One portion of the block 19 may overlap the remaining portion thereof providing longitudinal shoulders 21 and 22 at each end of said block.

In addition, the overl pped portion of the block 19 may be'oifset with respect to the portion of the block, forming transversely extending shudders 28 and 24, said shoulders being staggered with respect to each other. To join adjacent horizontal rows of blocks 19, auxiliary insert blocks 25 may be positioned between said adjacent rows as shown best in Fig. 4. One portion of the blocks 25 may be offset with respect to the remaining portion thereof forming shou1-; ders 26 and 27. j

In laying the blocks 19 and 25 to form a suspended refractory wall, transverse apertures are provided between shoulder 26 of the block 25 and shoulder 22 of the block 19 and also between shoulder 27 of the block 25 and shoulder 21 of the block 19. These apertures may be filled with a packing material 28 similar to that used in the suspended ceiling at 12 and 14. It can readily be seen that the junctures between blocks 25 and blocks 19 are broken and said broken joint is sealed by the packing material 28. In addition to sealing the junctures between blocks 19 and blocks 25, the longitudinal juncture between adjacent blocks 19 may also be sealed, said sealing material being disposed in apertures formed by the transversely extending shoulders 23 and 24 of adjacent blocks 19. This construction is shown particularly at 29 in Fig. 5.

It is to be understood that my invention broadly contemplates the joining ofadjacent refractory blocks, said surfaces of juncture being sealed by a suitable sealing material to prevent the passage of gases through said junctures. -It is also to be understood my invention is susceptible of being carried out by using a plastic material or by using blocks which may be inserted in the apertures formed by the overlapping portions of the various refractory blocks. My invention may be used in steam generating furnaces, cracking stills, 'ovens, kilns, or in general, in any installation wherein it is desirable to insulate a combustion or a heating chamber.

I claim as my invention:

1. A refractory lining for furnaces or the like which comprises, a plurality of refractory blocks having portions thereof offset with respect to remaining portions, forming shoulders on each of said blocks, a shoulder of one of said blocks being shoulders on each of said blocks, one of said shoulders being staggered with respect to another of said shoulders to form apertures between the shoulders of adjacent blocks, and a packing material inserted in said apertures.

3. A refractory block for a furnace wall construction having a portion thereof offset with respect to the remaining portion, forming shoulders on said block, one of said shoulders being staggered with respect to another of said shoulders to form apertures between the shoulders of adjacent blocks when laid to form a wall and a packing material inserted in said apertures.

-'4. A suspended refractory wall construction which comprises, a plurality of rows of refractory blocks each of which has an overlapping portion, said overlapping portion being offset with respect to the remaining portion, a row of auxiliary blocks interposed between each of said former rows of blocks, said auxiliary blocks having portions overlapping remaining portions thereof, an overlapping portion of one block being spaced from an overlapping portion of an adjacent block to form apertures, and packing material disposed in said apertures formed between the overlapping portions of the primary row of blocks and the auxiliary row of blocks.

5. A suspended refractory wall construction which comprises, a plurality of rows of refractory blocks each of which has an overlapping portion, said overlapping portion being offset with respect to the remaining portion, a row of auxiliary blocks interposed between each of said former rows of blocks, said auxiliary blocks having portions overlapping remaining portions thereof, an overlapping portion of one block being spaced from an overlapping portion of an adjacent block to form apertures, and packing material disposed in said apertures formed between the overlapping portions of the primary row of blocks and the auxiliary row of blocks and between the offset portions of adjacent blocks of the primary rows.

6. A refractory wall construction comprising a plurality of refractory blocks positioned adjacent each other, each of said blocks having portions projecting toward adjacent blocks forming shoulders on said blocks, the shoulders of adjacent blocks being spaced from each other to form apertures therebetween and packing material inserted in said apertures.
