(Cl. ‘l2-401) This invention relates to improvements in the such wall, the section being taken on approxi construction of furnace walls of the type wherein' mately line 2-2 of Fig.> 1; Fig. 3 is a side elevational view of a slab-re the furnace chamber wall is formed of refractory taining member employed in the wall construc blocks or tiles which are supported on an external 5 metallic framework. One of the objects vof the present invention is the provision df an improved construction for supporting the wall in sections upon the metallic framework in such fashion that the refractory 10 blocks and tiles which make up the sectionsare retained in proper position and may be assembled tion; of Fig. 1; - . Fig. 5 is a detail showing a section at line 5-5 of Fig. l; and heat through the wall. ` A particular object is the provision of a con struction wherein the refractory wall may be effectively insulated for the purpose of avoiding 2-0 loss of heat, and which is particularly adapted to y ' - . Fig. 6 is a face view ‘of a refractory block tile employed in the construction. ` ' - An understanding of the invention will be most quickly had from a detailed explanation of the construction here illustrated, which will now be )inV the wall structure, and removed therefrom " for purpose of replacement, with facility. Another object is the provision of a construc 15 tion which will be effective to minimize loss of ' Fig. 4 is la detail-showing a section at line 4_4 described. _ _ ' . 15v The principal load-carrying members of the wall structure are columns I0, which are struc tural v steel members preferably of I-eross-sec tional form. These are arranged in upright posi tion at intervals along and exterior of the furnace 20 , facilitate the assembly of the construction and , chamber and have suitable foundation support at their lower ends. To the inner ñanges Illa of ' also the removal and replacement of the insula tion and the wall refractories for purposes of in spection or repair. . VYet another object is the provision of an im proved construction wherein-an external sheath ing o'f plate or sheet sections is carried on the metallic framework in such fashion as to consti tute an effective external covering or ñnish 30 sheathing which may be assembled with facility and dismounted sectionally to afford access to the insulation and the wall refractories and the mem bers whereby they are supported on the metallic supporting members. , 35 ' ’ ' Other and further objects of the invention will - be pointedl out or indicated hereinafter or will be apparent to one skilled in the art upon an under standing of the invention or its employment -in use. „ 40 - For purpose of aiding in an explanation of the the column members I0 are secured transverse frame members il, which extend horizontally from one column member to another. These 25 transverse frame members are made of a suitable heat resistant material. such as cast iron, and are provided with top and bottom flanges extending both inwardly and outwardly, and also with4 an upwardly extending bracket-retaining flange I Ia. They are mountedf-on the ilanges Illa of the col umn members bymeans of bolts I2 which pass through said iianges, and they are provided with bolt holes IIb at intervals along their length. Each adjacent pair of column menibers thus sup ports a plurality of transverse frame members I I one above another at the side toward the furnaceY chamber. On each of the transverse frame members I I is mounted a series of brackets or'hangers Il, which are made of a suitable strong heat resistant ma-`forming a part of this specification. and herein ` terial such as cast iron. Each hanger comprises after describe, one form of structure in which the a plate-like body Portion having a hook I5 adapt ed to engagethe outer side of the flange IIa and invention may be embodied.- _It is to be under 45 stood, however, that this is presented merely for rest on top of the horizontal supporting member 45 II. The body portion also has a foot I6 adapted purpose of illustration and hence is not to be construed in any fashion calculated to limit the to abut the inwardly extending iiange at the lower edge of the frame member lI.

'I'he ~body member 50 In said drawing 50 extends for a distance inwardly from the trans Fig. 1 is an exterior elevational view of a por tion of a -furnace' wall, some of the parts being verse frame member and is formed with a -down shown in section and some of the parts being wardly extended arm I1 and a narrow laterally .. invention I show in the'accompanying drawing _ broken away to show interior parts; Fig. 2 is a sectional view through a portion of projecting shelf Il at each side. At its inner . margin the body portion and leg I‘l are provided 55 i 2 2,110,419 with laterally extending lugs I9, 2li, 2|, and 22projecting from each side. The lugs |9 and 2| are in alignment with one another longitudinally of the body portion, while the lugs 20 and 22 are likewise in alignment with each other but offset inwardly of the body portion from the- aligned lugs I9 and 2|. These brackets, supported on the transverse frame members || as above de ber, I provide slabs 39 and 3| of insulating maie Irial. These slabs are of size convenient for handling, the slabs 30 preferably being of a height corresponding to the vertical spacing of the brackets i4 and of a width corresponding to the 6 horizontal spacing of said brackets, and the tiles 3| preferably being of a height corresponding to the height of the body portion of the brackets V Y scribed, are arranged with those on one frame and of a width corresponding to the horizontal 10 member in verticalalignment with those on the ' spacing of the brackets.~ 'I'he slabs are placed 10 subjacent or superjacent frame member. against the outer ends of the wall refractories, the The refractory wall is- built up of refractory tiles which, for the most part, may be of the form shown in Fig. 6, with series of projections 15 24 and seats 25 on portions oi' their top, bottom and side faces. Adjacent their outer ends these tiles, which are designated by the numeral 23 in Fig.’2, are provided with lateral grooves 26 and 26a, the width of said grooves being but slightly 20 in excess of the overall distance between the _re slabs 39 resting at their lower ends on top of the brackets and the slabs 3| being disposed between the brackets and resting on top of the slabs 3l. vThe slabs are retained in place against the wall 15 refractories by holders 32.' These are rigid plate like members and may be made of cast iron. They are somewhat longer than the slabsJl, and on their backs or outer sides have wedge-shaped projections 32a. 'I'hese slab holders are inserted 20 downwardly between the transverse frame mem mote vertical sides of the bracket lugs 2li and 2|.

Accordingly, the holding member may be 25 tion. The horizontally associated brackets I4 are spaced at intervals corresponding to the width of ` two of the tiles 23 and eachhorizontal row of brackets supports a wall section independently At the'bottom of each section is a row of base tiles 21, each of which is of sumcient width to span the distance between two of the brackets, its sides resting on the shelves I8 thereof. The tiles 21 are grooved at 30 of the section below it. 35 their sides, said grooves accommodating the lugs 20 and Ylowermost lugs 2| of the brackets. The lug 20 contacts one vside of the tile groove and the lug 2| the opposite side, and thereby the tile 2| is retained against tilting, its inner end por 40 tion projecting for a substantial distance inward ly from the brackets. - 'I'he lowermost course of tiles 23 is laid on the tiles 21, said tiles being arranged in pairs between the adjacent brackets, the groove 26 of one tile-of the pair being en 45 gaged with the lug 22 and the intermediate lug driven down to such an extent as may be neces» sary to hold the slabs against the outer ends 'of the wall refractories. ' ` To provide an outside finish sheathing or cas ing and an insulating dead air space, I employ a plurality of sheet or plate sections 3l. These are somewhat wider than the distance between the flanges Ilia of juxtaposed column members, and somewhat shorter than the vertical distance between the bolts i2. For mounting them in place, I place‘bolts 35 in the bolt holes IIb oi' the transverse frame members, securing them in place by nuts 36. The sheet sections 3l are in- y serted between the`adjacent column members until their lateral marginal portions come to rest 40 upon the ñanges Illa, their lower margins being` supported on the bolts 3l. Batten strips 31 which are punched to receive the bolts 3l are then threaded -thereon in overlapping relationship to the marginal portions of the adjacent sheet sec tions 34. Batten clamps 33 are provided, each being shaped to accommodate the end, portion 2| of one of the brackets, and the groove 26a of the other tile of the pair being likewise Ven gaged with those lugs of the adjacent bracket. 'I'he tiles 2| extendinwardly for- a substantial distance beyond the inner ends of the base tiles 21, and they are retained against tilting by en oi' `a batten strip 31 and to fit against the nange Ita and web Ilib of the column member and also being-apertured .to accommodate a bolt i2. Angu lar sheet clamps 39 are provided, same being gagement of the lugs 22 and 2| with opposite shaped in conformity with the angular relation sides of the tile grooves. The section is then " ship of the ñange and web of the column member, ' built on upwardly with additional courses -of tiles- and being apertured for accommodation of the 23 arranged as described in the above mentioned bolt 40. One or more of the sheet clamps 3l are copending application, some ofthe tiles in the disposed at each lateral margin of a sheet section, upper courses of the section being engaged with ‘ 3l, the web of the columnmember being punched the lugs I9 of the superjacent brackets, and the projections and seats of thetiles in one course be ing intermeshed with those of the tilesl in’sub-4 jacent and superjacent courses. At the top of the section short tiles 23 ?ll the space between the inner ends of the base tiles 21 and the inner ends of the .tiles 23', and îlayers of refractory joint packing material 19 are interposed ‘between the uppermost tiles in 'one section and the lowermost tiles of the superjacent section to seal the joint and allow for vertical expansion. By virtue of the „to accommodate the bolt 4|). ` It will be appreciated that _the flanges of struc tural steel members, such as I-beams, are,‘customarilythinner at their margins than at the web, 'and consequently that their inner surfaces "are not at right angles to the web.
