. INTEIRLOCKING CHAIN WALL Filed May 21, 1958 6 Sheets-Sheet 6 INVENTOR. L e vi 5. Longenecker yam, 725.41% M HIS ATTORNE Y5 Unit This [invention relates to wall structures and particularly, to an improved refractory block or tile construction and assembly therefor. A more specific phase of the invention deals with an interlocking or chain type of hung wall that may be employed as a baffle or curtain wall, a door lintel or an end wall of a furnace construction.
Prior to my invention there have been two general types of hung curtain walls. In one, the wall is made up of symmetrical or substantially like-shaped full length I- beam tiles which interfit sidewise with each other by means of their upper and lower flanges. The disadvantage of this type is that there is no practical way of obtaining enough pressure from the ends of the tiles to keep them firmly meshed. In this connection, it may be noted that the tiles extend fully endwise of the width of the wall. As a result, there is a tendency for failure, particularly on larger jobs, by reason of the lack of means to keep them firmly meshed. This type of tile, however, has the advantage that it can be formed from itssides, since there is no undercutting involved.
In a second type of construction, as in the first type, the tile members are of the same construction and interfit sidewise of the wall, but have flanges that are under-cut so as to provide an interlocking relationship. This type of tile, however, must be made, as a result of the undercutting, by press-forming it from its ends, with the result that the tile or block is relatively weak and does not stand up well in service. The tile or block of both types of constructions are of an I-beam shape, except that the tile of the first-mentioned construction has substantially planar and parallel undersurfaces along its flanges.
My construction has been developed to incorporate the advantageous features of the prior art constructions without their disadvantageous features, in order to provide an improved interlocking wall whose tile or block members are of a relatively strong and long-life type. I have been able to meet the basic factors of strength and interlocking ability by employing a plurality of blocks in a novel type of system, arrangement or assembly. However, all of the blocks or tiles are of such a nature or shape that they can be made by sidepressing, as distinguished from end-pressing. In addition, the assembly is such that a third factor of permitting heat expansion without damage has also been taken care of.
It has thus been an object of my invention to develop a solution to the problem which has heretofore been presented in the construction, assembly and utilization of refractory tiles or blocks to provide an improved curtain, interlocking or chain type of arrangement; Another object has been to devise a new and improved tile or block assembly system or interfitting combination and to provide block or tile members suitable for cooperative utilization therein;
A further object of my invention has been to provide a refractory block or tile wall construction suitable for furnace utilizations under stress, strain, and expansion conditions that are inherent in such utilizations;
' A still, further object has been to provide a new and improved type of wall construction in which the interlocking members may be formed by a side-pressing operation and which members, when utilized, will stay in position and permit necessary expansion and contraction, and will provide a wall with a better and more trouble-free operating life;
' These and other objects will appear to those skilled in the art from the description and the claims.

FIGURE 17 represents a full length transverse tile of angle shape having a quarter of the section of the type of FIGURE 9 and half the section of the type of FIGURE 13 for finishing vertical ends of the wall.
As shown particularly in FIGURES 1, 2 and 3 of the drawings, I have provided a load-supporting or overhead I-beam member 21} as a means for supporting or suspending a refractory wall constructed in accordance with my invention. As illustrated, particularly in FIGURES 2 and 3, the beam 20 has a lower flange 20a that is connected at staggered positions along opposite sides of its web by longitudinally spaced-apart vertical rib portions 20b that are also connected to the top flange. Hangers, support members, halves, castings, or parts 21 and 21' are shown mounted in a staggered relationship with respect to the vertical rib portions 202;, and with respect to each other over opposite side edges of the bottom flange 20a, and on opposite sides of the web of the load member 20.
The hangers or support members 21 are shown provided with two pairs of clamping tongues, brackets, hooks or feet portions 210 that, at their upper end portions, are
integrally secured in a longitudinally spaced-apart upright relationship along a clamping channel portion 21a. The portion 21a fits over and extends along one of the side edges of the bottom flange portions 20a of the loadcarrying member. The hook or foot portions 21c, at their other ends, are integral with and constitute web portions for'a block-supporting flange 21d that extends transversely from opposite sides of the portions 210 and at right angles to or crosswise of the flanges 20a of the beam 20. As shown in FIGURE 3, shorter length hangers, support members or castings 21' are also provided and are of the same construction, except that they have'only a pair of hooks or feet portions 21c (see also FIGURES and 7), each of which has a block or tile supporting bottom flange portion 21d. Other portions of the hangers 21' that correspond to the full size hangers 21 are distinguished therefrom by prime suffixes.
As shown particularly in FIGURES 2, 3 and 5, the hangers or hanger parts 21 and 21' are in a horizontallystaggered relationship with respect to each other along the bottom flange a of the load member 20, and are securely clamped together by bolt and nut assemblies 22. This staggered relation causes them to serve as a lengthwise binder to hold the top courses of transverse wall tile in mesh. It may be noted that longitudinally-extending, interlocking cross key tile 26 accomplishes the bind: ing for the remainder or bottom portions of the hung wall, thus my interlocking type of hung chain wall will hold together without any heavy pressure from its ends.
As shown inFIGURES 1, 2, 3, 5, 6, 7, 8 and 9 of the drawings, I have provided what may be termed substantially full length I-beam shaped full length transverse tile or blocks 23 which hold together half-length tile extending in the same direction along the thickness. of. the wall construction; The full length tile 23 are carried in a top group or interlocking clusters with respect to each other adjacent to suspension fingers or brackets 21cand 21c, as shown in FIGURE 8 of the drawings, to interfit and cooperate with half length intermediate blocks or tiles. There is also a bottom group or cluster that interfit and cooperate with half length intermediate blocks or tiles. They also lie in vertical rows of blocks that are vertically spaced with respect to each other by half-length transverse filler blocks or tiles 25, of I-beam shape. Thus, the filler blocks which also help to carry the vertical load, cooperate with the transverse blocks 23 to. define vertical rows in the wall construction, endwise of its thickness. The transverse blocks 23 lie in vertical rows that are horizontally spaced by vertically-aligned rows of main load support, suspension tie, half-length, transverse blocks or tiles 24.
It should be noted that the half or short length filler blocks 25 lie in the same vertical rows as the transverse blocks 23, and that the latter do not lie in the same horizontal rows as cross key, longitudinal blocks or tiles 26 of rectangular shape. The interlocking relation of the key tiles 26 is primarily eifected with respect to the vertical, load-carrying, transverse blocks 24. Each block 24, as shown particularly in FIGURE 10, has shortened flange and web portions that are defined by a half depth, cut-out or inwardly-offset end portion 24a. The ofiset or cut-out end portion 24a is provided by a step portion 24b and a riser portion 240. This leaves substantially the other depthwise half of the block 24 with an endwise-projecting portion 24d.
On the other hand, as shown in FIGURE 12, the cross key or longitudinal blocks 26 are shown of rectangular shape, with opposed (upper and lower) narrow side walls, and opposed (vertical) Wider side walls. The cross key or longitudinal blocks may be of any suitable shape, but should have tongue and groove portions for interfitting with other blocks. or cut-out portions 26b provide top and bottom alternate, cross summit, tongue or shoulder portions 26:: and 266' that are separated thereby. It will be noted, as shown in FIGURES 1 and 2 that the cross key blocks 26 Cross groove, inwardly-oflset, slotted extend in horizontal rows that are spaced vertically with respect to each other, see the upper and lower rows A and B of FIGURES l and 2.
As to the key block row A, the short length or cut-out end portions 24a of a horizontally-aligned adjacent pair of half-length rtile 24 are positioned to cooperate with and abut against opposed vertical or wide side walls of the key tiles 26. The projecting or greater length end portion 24d of one tie tile 24 is positioned to project halfway into a slotted portion 26b of a key block 26 in endwise alignment and into abutment with a similar end of a horizontally-adjacent second tile or tietile 24; The oflset or cut-out web portions of both such adjacent tie tiles 24 are also positioned to project halfway into the same slotted or groove portion 26b of the same key block 26 to interlock therewith.
As to the same longitudinal key block of row A, it will be noted-that the lower flange portions of an upper transverse pair of-horizontally adjacent tie blocks 24 rest upon the upperflange portions of a vertically adjacent, next lower, transverse pair of horizontally adjacent tie blocks 24. The shorter length end portions of the-upper and lowerpairs of tie blocks 24 lie adjacent to each other and abut against the opposed wide sides of. the same key block 26. Thus, the extending end portions of the lower pair or" biocks 24 fit within a slotted portion 26b on an under, narrow side of the same key block 26,,in1 vertical alignment with the extending end portions of the upper pair of blocks 24 that project within a similar slotted portion 26b on the upper, narrow side of the same key block.
In FIGURE 1, the block row B illustrates how transverse pairs of filler blocks 25 are positioned in end-abut- 'ment' with opposite sides of the key blocks '26, but do not directly interlock therewith, as do the tie blocks 24. However, the filler blocks 25 center abutting vertical ends of pairs of the key blocks 26 (see FIGURE 1). Thekey blocks 26 ofrows A and B (see FIGURE 2) pass between and have their top and bottom narrow'sides in abutment with the flanges of the transverse full-length blocks 23. The interfitting of the transverse blocks 23 with the filler blocks 25, of these blocks with the tie blocks 24, and of finish blocks, such as 23', 23", 25, and 27, is efiected by their flange portions. Half length key blocks 26'' and full length key blocks 26 interlock with tie blocks 24 through the agency of the tongue and groove portions of the former and the ofiset end portions of the latter.
As shown in FIGURE 1, see row A, four tie blocks 24, see (1), (2), (3), and (4), form or define a doughnut type of interlock or assembly around one end of each key block 26. A similar type of assembly interlocks four more of, the tie blocks 24 with the other end of the same key block 26. It will be noted that a similar arrangement is employed in row B, but that the key blocks 26 of such row are staggered with respect to the key blocks 26 of row A to provide a continuous interlock from end to end of the wall.
In the various figures and, as shown particularly in FIGURES 9 to 17, inclusive, I have designated end or filler tile or block members by the same reference numerals (except 27 of FIGURE 16) as corresponding full section members, but by prime suffixes, and have designated quarter section membershby double prime suffixes. In this connection, the main block members are represented as 23, 24, 25 and 26. The half or quarter section members are employed for top, bottom, and end finishing of the wall, as shown particularly in FIGURE 1 of'the drawings. For example, the half horizontal sec. tion members 23' of FIGURE 13 provide bottom finish tile for the bottom group or cluster of full length members 23', and, the quarter section members 23" of FIG- URE l7provide top and bottom end finish tile for the full-length members 23 The half section. filler members 25' of FIGURE 15 provide vertical end finish tile-with half key members 26' of FIGURE 14.- The channelshaped members 27 of FIGURE 16 provide finish tile for the vertical ends of the wall and are vertical half sections of the transverse tile 23 that tie the half length tile members together. In this connection, the finish tile members 27 have their flanges interfitting with the flanges of outer rows of the tie tile members 24 (see FIGURE 1), and at the top and bottom of the wall, with full length members 23 of the top and bottom groups or clusters.
In accordance with my invention, the block or tile members are all shaped in such a manner that their flange or interlocking portions require no under-cutting or olfsetting, such as would necessitate making them by endpressing, as distinguished from side-pressing operations. Thus, all of my tile or block members have full strength for their curtain wall utilization. There are no weak tiles.
It will be noted that the wall is interlocked or keyed together by means of the longitudinal tiles 26 which are vertically staggered in horizontal rows A and B, in order to obtain the effect of a continuous binder. Each of the transverse tiles 24 is notched at one of its end corners to interfit with like-notched corners of adjacent transverse tiles 24 and to interlock with or into the longitudinal key tiles 26. The transverse tiles 25 serve to fill in space and help to carry the vertical load. The full length transverse tiles 23 hold the half-length tiles from splitting apart and bind the top and bottom portions of the hung wall.
It may be noted that the more completely the bearing flanges of the I-beam shaped tiles of my construction are held in mesh, the stronger and more durable is the hung wall. Any normal deflection of the supporting beam 20 will cause the tiles to loose up in the bottom rows at the center. However, no amount of pressure from the ends can prevent such loosing up, unless it should be great enough to carry the whole wall load, jack arch fashion, in which case the steel support is not needed.
In FIGURES 5 and 7, I have shown how a wall of my construction may be applied as a lintel for a door opening 32 of a heating furnace having a chamber 33, a refractory roof 3%) and a refractory floor 31.
