CASING.

Application filed April 13, 1927. Serial No. 183,434.

My present invention relates to casings which are particularly useful in conjunction` with heat insulating material for enclosing furnaces, boilers and the like, to prevent the passage of heat from such structures, although it will be understood that my 1nvention is not limited to this use.

My invention will best be understood by reference to the following description and the annexed drawings, in which I have illustrated one embodiment of my invention, and in which Fig. 1 is a fragmentary front view of a casing embodyingmy invention; Fig. 2 is a sectional view taken along the plane of the line 2 2 of Fig. 1; Fig. 3 is a fragmentary front View simlar to Fig. 1 and illustrating a small portionof Fig. 1 on an enlarged scale; Fig. t is a section taken along the plane of the line 4--4 of Fig. 3,v and Fig. 5 is a section taken along the plane of the line 5 5 of Fig. 3. I

Like referencev characters indicate like parts throughout the drawings. Y

For heat-insulating casings, in which, as indicated, my invention' is particularly useful, there is commonly provided a layer of heat-insulating material which is ordinarilyV covered on the exterior by a sheet metal covering. These coverings are made up of metallic plates, yand ordinarily the casing is further provided with stiffening members eX- tending along the sheet metal covering to hold Vthe parts in position, the ends of these stifening members being ordinarily connected to the framing of the furnace or other structure to which the casing is applied. The casing covering and the stit'ening members, as heretofore usually constructed, have been arranged so that there are large metallic paths for heat flow through the layer of heatinsulating material, thus nullifying to a large degree the effect of heat insulation. By my present invention, I provide a simple means for holding the parts of the casing in position which at the same time minimizes or entirely avoids any such metallic paths through the heat-.insulating layer.

In the illustrated embodiment of my infv vention, a refractory wall 10 is covered with a layer of heat-insulating material.indicated generally at 11, and here shown as comprising two

separate layers

111 and 112, andthe heat-insulating layer is covered by a Wall or easing comprising panel plates 12 which are unfianged, and of substantially uniform thickness throughout, and are preferably rectangular in form, so that they can readily be cut fromsheet metal into panels of desired dimensions; f he panels are preferably spaced suiiiciently to permit the passage of bolts through the joints therebetween as will be hereinafter more specifically described.

Gn the inner side of the panels 12 are located members extending in different directions, indicated generally at 13 (Fig. 3), which, when the wall or casing is vertical, preferably extend horizontally and vertically. The channel irons 131, which extend in one direction and whichmay be thehorizent-al channels when the casing is vertically arranged, are preferably continuous,` While the vertical channel irons. 132 are discontinuous and are fitted between the channel irons 131 and preferably secured thereto as by welding, as illustrated at 14 (see Figs. 3.and i) .l The channel irons 13 overlap the joints formed between the ypanels 12,A and the open sides thereof preferably extend zaway from thepanel plates as illustrated in Figs. 4 and 5, the channels preferably being filled with a hardened plastic materia-l as indicated atfl.

The ends of the channels 13 are preferably secured suitably (in a manner .not illustrated) `to ythe framework at the sides of the furnace or other structure, so that the chanv nels 13 constitute a rigid frame .which is selfhowever, are preferably deeper than those on the inside, and the vertical channels may beef greater. depth than the horizontal chan'. nels as best shown in Figs. 4 and 5. The one set of the outer chanenls, as 161, may also be continuous while the other set of channels 1,62 are discontinuous. The'outer continuous channels 161 extend at an angle yto the inner continuous'channels 131. The discontinuous outer channels 162 tit closely in between the continuous channels', but itis usually unnecessary that they-should be secured ing interposed between the edges ot the pane `jilates 12 and the channel irons 13 as best shown-in liigs. i and 5.

In the embodiment of my invention illustrated, Where the Wall or casing is used in conjunction with a body or layer ci heal' insulating material, sneh body is preterably made up oi tno layers, the one compris ing blocl-:s 111 vwhich may be termed of ma terial commonly known as iire backing, and which `are preferably oit the same depth as the channel irons 13, so that the edges of the channel irons and the inner tace ol the blocks 111 lie in the same or substantially the sameplane. The body of heat-insulating-g,` material 11 also comprises an inner layer 112 which may be formed ci ,iloclrs oi fire backing which are .Fitted together, and the joints of which may 'overlap'withthejoints between the blocks 111.

lt Will be evident that my invention pros vides a Wall or a casing comprising a pir.- rality ot separate panel plates which are et substantially uniform thickness and which may readily be formed and assembled in posi# tion and that these `plates are held in position by a simple yet rugged structure, and Without the necessity ot providing holes in the panel plates for bolts, thereby correspondingly simplifying` the construction. The construction also provides for the replacement of an individual panel, Without disturbingthe position of those adjacent.

It will also be evident that no metallic paths are provided through the layer oit heat-insulating material, in conjunction with which l have illustrated my invention, which makes myinvention particularly usetultor this purpose.

It will be understood that the arrangement which I have described merely illustrative and that the embodiment oil my invention may be modiiied.` It will also be understood that the Wall or casing` comprising the panel plates 12 and the structure by Which these plates are secured in position may be used independently of the heat-insulating layer.
