FURNACE WALL Fld June 4, 1928 L INVENTOR. 3-3 3 L e@ f7. 560// ATTORNEY Patented Aug. 19, 1930 PATENT oFFlcE LEE .'MI. BEALL, OF TULSA, OKLAHOMA FURNACE WALL Applicationmled .Tune 4, 1928. Serial No. 282,536.
My invention relates to furnace wall construction and more particularly to a sectionally const-ructed furnace wall including supports for spacing'and supporting each section individually from an outer wall.
' The principal object of the present invention is to permit removal of any one of the inner wall sections so that repairs or re- 1 placement 'of parts in a section may be made without removing adjacent sections of the wall.
A further object of my invention is to provide for cooling the inner furnacewall by t-he circulation of air through the space between the walls, and for equalizing the temperature of the air passing to a burner by interrupting its flow around the support brackets interposed between the walls.
Another object of the invention is to provide novel means for sealing the joints between upper and lower ends of adjoining wall sections and to permit vcontraction and expansion of the inner wall.
In accomplishing these and other objects of my invention I have provided improvedw v details of structure, the preferred forms of which are illustrated in the accompanying drawings, wherein:
Fig. 1 is a perspective view of a fpart of a furnace Wall from the inside thereo showing parts broken away for better illustra-I tion of the wall supporting means.
Fig. 2 is a side elevation of part of a wall illustrating the method of supporting a wall spaced relation with-the outer support wall.
Fig. 3 is a section on the line 3 3, Fig. 2, illustrating the assembled relation ofthe cap blocks and base blocks of ad'oining wall sections and the mounting of a ase block on its support bracket.
Fig. 4 is a sectional` plan view of the cap blocks on the line 4 4, Fig. 2, showing the blocks in locked engagement with thesupport bracket.
Referring in detail to the drawings:
l designates a double furnace wall including an outer wall 2 and a -spaced inner wall 3, the inner wall forming an enclosure for burners, boilers or the like, the outer wall defining an air space 4 between the walls so that air passing to the burner circulates through the space and tends to cool the inner wall.
The outer wall 2` constructed of ordinary brick 5 is reinforced on its inner side by a steel framework 6 including vertical buck stays 7 equally spaced about the wall, and horizontally disposed H beams 8 secured to the buck stays and vertically spaced thereon for receiving support brackets 9 supporting the inner wall 3 hereafter described.
Each support bracket 9 includes an upper horizontal rail portion 10 having at one end a rectangular-shaped plate 11 horizontally and centrally disposed with relation to the rail, the rail extending'rearwardly from the plate and terminating in an upwardly protruding hook 12 engageable with the outer and lower flange 13 of the H beam 8.
Formed at right angles and extending downwardly from the rail portion 10 is a web plate 14 cut away at its sides and bottom end, thus forming a head portion 15 and angularly disposed legs 16 and 17. y.
The head 15 is provided at its outer end with a plate 18 depending vertically and centrally with relation to the plate 11 from a point adjacent theinner edge of the plate 11 and extending transversely with relation to the web 14.
Provided at the bottom of the leg 16 .is a foot portion 419 resting on the web of the beam 8, with the outer edge ofthe foot engaged with the iiange 20 of the beam so that the Weight of a wall section 21 resting on the late 11 causes the foot to fulcrum in the eam and the hook 12 to engage with the flan e 13 of the next higher support beam 8.`
Tie leg 17 spaced outwardly from the leg 16 is provided at its lower end with a vertically extending foot portion 22 positioned at a substantially central position below the plate 11 and adapted for engagement with parts of the inner wall 3, presently described.
The wall 3 is composed of a plurality of the sections 21 (Fig. 2), each section being supported by one of the brackets 9 and consisting of a base block 23, standard lire brick 24, cap blocks 25 and a sealing element preferably asbestos rope 26, which is applied between adjoining sections for providing an air-tight and flexible joint, and permitting explnsion and contraction of the assembled Wa The base'blocks 23 are provided with an undercut bottom 27 to permit clearance for the support plate 11 with the underlying cap blocks 25 and the shoulder 28 formed by the undercut serves as a stop for engaging with the outer edge of the plate 11 and aligning the blccks in the wall.
Grooves 29 are also provided in the outer bottom portion 30 of the base blocks for alignment with like grooves 31 in the upper surface of the cap blocks so that the asbestos rope 26 may be applied in the grooves for spacmg the blocks and serving as resilient sealing means to permit contraction and exp ansion of the wall between adjoining sections. v
Assuming a wall section to be constructed at an intermediate position in the wall as shown in Figs. 1, 2 and 3, a bracket 9 is placed in position on the beams 8 and in proper spaced relation with the bracket of a previously assembled section. A base block 23 1s placed on the plate 11 of the bracket 9 and shifted laterally for abutment with the base block of the adjoining section. The notch 32 on the abutting side of the block engages wlth the foot' portion 22 of the next hlgher bracket, a part of which engages with the notch 32 of the adjoining abutted block. When the block 23 is in abutment with the ad]o1n1ng block, its side edges are equally spaced from the side edges of the plate 11 and the shoulder 28 of the block is in abutr ment with the end edge of said plate, as shown 1n Fig. 2.
Next inthe order of assembly the lire bricks 24 are laid on the base block in alternate f form and the cap blocks 25 are placed on the lire bricks for capping the section.
The cap blocks 25 are provided with vertical. grooves 33 in their side walls at a point ad] ac ent their inner ends, and in assembly on a section, the blocks are shifted into abutment from opposlte sides of the bracket 9 so that the grooves engage over the side edges of the plate 18. A spacer brick 34 is placed between the paired cap blocks of adjoining sections, so that upon removal of the spacer brick, the cap blocks may be shifted laterally from locked engagement with the plate 18,
thus` permitting dismantling of the section for repair or replacement of its parts.
What I claim and desire to secure by Letters Patent is:
1. In furnace wall construction, an outer wall, an inner Wall, horizontal vertically spaced supports on the outer wall, superimposed brackets mounted on lower supports and anchored to upper supports and carrying the inner wall in spaced relation to the outer wall, and means for locking the inner` wall to the supports.
2. In a furnace wall construction, an outer wall, a framework re-enforcing the wall, an inner wall comprising superimposed sections, brackets hooked to the framework of the outer wall, seats on the brackets engaging under the wall sections, and a foot on each bracket for engaging the top of the next lower section.

4. In a furnace wall construction, an outer wall, a framework re-enforcing the wall, an inner Wall comprising superimposed sections, each section having overhanging ledges provided with sockets on their upper faces and recesses on their under faces, and brackets mounted on the framework having seats for engaging in said recesses and feet for engaging in said sockets to support and space the inner wall from the outer wall.
5.
