R. W. JONES REFRACTORY WALL May 4, 1965 3 Sheets-Sheet 5 Filed Jan. l2, 1959 INVENTOR, /erzf .7277651 L UnitedA States Patent O 3,181,273 REFRACTURY WALL Robert W. Jones, Birmingham, Mich., .assigner to yEhe Bigelow-Liptak Corporation, Detroit, Mich., a corporation'of Michigan Fiied 1an. 12, 1959, Ser. No. 736,340 3 Ciairns. (Ci. 59u41@ My invention relates to refractory walls and, in particular, to refractory Walls made up of a great number of individual refractory elements that are supported upon a metal framework.

It is an object of my invention to provide a refractory wall construction which may be readily made of various thicknesses.

It is also'an object of my invention to provide a refractory wall which is somewhat less expensive than conventional walls now known in thefield.

My invention employs a construction in which there are three different refractory elements. One of these, a holding tile, is supported by a metal casting on the metal framework. Pairs of holding tile support a beam tile; and the combination of holding and beam tiles eX- tend in horizontal rows which are verticaily spaced from eachother. in between these horizon-tal rows are rows of service tile which are supported by the holding and beam tile, all ofv which are supported by the metal castings which hold the holding tile in place.

The invention will be described in more detail in connection with a description of the accompanying drawings in which:

FGURE 1 is a perspective view, broken away, looking at the tire face of a refractory Wall constructed in accordance with my invention;

FGURE 2 is a vertical cross section through a part of the wall of FIGURE 1;

FIGURE 3 is a horizontal view partly in section of the wallof FGURES 1 and 2;

FIGURE 4 is a perspective view of the holding tile;

FIGURES is a perspective View 'of the beam tile;

FIGURE 6 is a perspective View of the service tile; and

FIGURE 7 is a perspective View of a slightly modified form of Awall employing the invention and one which is particularly well suited for very thinwalls, such as 2" suspended walls.

The wall 1 has a re faceprovided by three diiferent types of refractory tile, viz., holding tile 3, beam tile 5, and service tile 7. All of the tile are carried by metal castings 9 upon which the holding tile 3 are mounted. r'he castings 9 are bolted to a steel piate or shell 11 which acts as a sink to drain heat from the `C-shaped castings 9. The tile and 7 are of the same thickness, as can be seen in FGURES 2 and 3, and spread over their outside faces is a thin layer of plastic insulation 13 of a known composition acceptable in the field. Between the layer 13 and the shell 11 is block insulation 15. A vapor seal 1e may be interposed between the shell 11 and the layer 13.

Each holding tile 3 comprises a front or inside face 17 which forms a part of the re face of wall 1. The top side `of the tile 3 has adjacent the face 17 a groove 19 to receive a tongue projecting from the bottom of tile '7. A similar groove 21 is formed on the bottom side 'of the tile 3 to receive a tongue projecting from the top of tile 7. The top of the back portion of the tile 3 is reduced in height, as seen in FiGURE 2, and opening out of the top is a groove 23 having a rear `side which is parallel to the face 17 and a front side which is tapered so as to facilitate the insertion of the tile 3 in a hanger casting 9. The bottom of the tile 3 adjacent the outer or back portion has a groove 25 to receive the projections 27 on the hanger 9, the top projections 29 on the hanger 9 fitting in the top groove 23 as can be seen in FIGURE 2.

The beam tile 5 are supported between pairs of holding tile 3 and t into recesses formed in the sides of the holding tile 3. These recesses comprise a section 31 that extends from the top to the bottom of the tile 3 and a section 33 which extends from the top of the tile 3 to a fiat upwardly facing shoulder 35, the recess portion 31 thus being narrow along the bottom half of the tile 3 asindicated at the section 37. The ends of the beam tile 5 are shaped to fit into the recesses 31 and 33 in the ends of the hoiding tile 3. Thus the back half of each tile 5 is longer than the front face to provide a vertical section 31a ruiming the full height of the tile S and a section 33a running a part of the height and which has a bottom face 35a to seat on the shoulder 35. The end of the tile S aiso has a narrow lower section 37a that fits in the section 37 in the end of the tile 3. The beam tile 5 has grooves 39 and 41 formed in the top and bottom, respect tively, which line up with the grooves 19 and 21 in the holding tiie 3 to form grooves running'the length of the tile rows that receive tongues projecting from the top and bottom of the service tile 7.

The service tile 7 are arranged so that their length eX- tends vertically, and the top and bottom ends have tongues i3 and d5, respectively, which project into the grooves 19 and 39 and 21 and 41 already mentioned. On one vertical side the tile 7 has a groove '47, and on the opposite vertical side it has a tongue 49 which will iitinto the groove 47 on the adjacent service tile.

As seen in FIG. 2 `substantial clearance is provided in the tongue and groove joints between the tile 3, S, and '7, and these are lled with fairly thick layers of lire clay mortar in which the tile is set. Upon heating, the fire clay shrinks and'becomes hardened and furnishes substantial space for expansion of the' tile.

ltwill'be noted that theV hanger castings 9, by virtue of the spaced pairs of fingers 27 and 29, have a minimum area of contact with the holding tile S and thus a mini mum contact with the hot surfaces of the wall 1. On'

theother hand, a very substantialarea 51 on the back of the casting 9 is in engagement with thesteel plate 11. Therefore, there is asmall area for heat to enter the casting 9 and a large area 51 for it to be drained from the casting 9 into the plate 11, thus tending to keep the castings 9 at a relatively low temperature. The engagement of the projections 27 and 29 in the grooves 25 and 23, respectively maintains the tile 3 in a horizontal position despite the load of the other tile 5 and 7 and the load lof the mortar and the plastic insulation 13.

FiGURES 7 to 10 show a modified form of wall 101 in which the tongue and groove type joints between the tile are modified to permit the tile to bel made of less thickness than in the previous design. In the wall 101 the holding tiie 103 carry beam tile 105 and the combination of tile 103 and 105 carry rows of service tile 107. The holding tile 103 are mounted on alloy casting hangers 9 which are identical to those previously described, but in this case are bolted to horizontal channels 109. The fire face of the service tile 107 are shorter than the outer faces so that there are tongues 111 projecting from the top and bottom ends 'of the service tile at the outer faces. These tongues 111 t in grooves 113 in the top and bottom faces of the holding tile 103, these grooves correspending to the grooves 19 and 21 in the tile 3. The beam tile have higher fire faces than they do outside faces, thus providing grooves or cutout corners 115 to receive the projecting tongues 111 on the service tile 107. Projecting from opposite ends of the beam tile 105 and Patented May li, 1965l 'D e.) in vertical alignment with the cutout corners 115 are tongue portions of an L-shape, each comprising a wide portion 117 and a narrow portion 119. These are received in recesses 117e and 119e which are complemental to the tongues 117 and 119 and formed by an inverted T cross section in the holding tile. There is a shoulder 121 in the tile 103 between the recesses 117:1 and 11% which faces upwardly and resting on it for support is the downwardly facing shoulder 123 between the projections 117 and 119 to thereby transfer load from they beam and service tile into the holding tile.

It will be apparent that the above constructions may be modified without departing from the spirit and scope of the invention.
