OVEN-WALL CONSTRUCTION.

Application tiled July 1.6, 1923. Serial-No. 651,997.

to provide a wall or partition which is light in weight but which will, nevertheless, be eflicient in the matter of insulating against heat and cold the spaces enclosed or separated thereby.v A further object of the invention is to provide a wall or panel construction which is durable and in which the exterior surface may be of metal, withl interposed braces or'stanchions to which the exterior wall sections may be conveniently secured and without the necessity -for employing a m'etal-to-metal contact between such external surfaces. My invention is particularly adapted lfor Athe construction of ovens, such as core, enameling and heattreating ovens. A

I accomplish` the foregoing object and more limited objects which will appear hereinafter, in and through the construction and arrangement of parts shown in .the drawings, wherein Fig. l represents,V a

horizontal sectional view through the corner of a room or building having my invention applied thereto; Fig. 2 a vertical section on the line 2-2 of Fig. l; and Fig. 3 a detail in horizontal section showing the manner in which contiguous panels may be conveniently united.

Describing by reference characters the various parts illustrated herein 1 denotes the outer and 2 the inner sheet metal covering* for the Wall. Each of these covers has adjacent thereto a sheathing 3 of heat-insulating material, such as magnesium board or the like, molded into suitable sheets. My invention m'ay be conveniently embodied in panels, each panel havwall sections 1. 3 and 2, 3 thereof, an upper spacing and frame member 4,4 a lower spacing and frame vmember 5, and vertical spacing and frame members 6. In addition to the upper and" lower members 4 and 5,' each panel may have one Or more intermedlate horizontal memor panel by tions fthe -walls or panels.

bers 7 and one or more vertical members 8, according to the dimensions of the panel and the frequency of the bracing required between the opposed sides of the wall or panel.

For the members 4, 5, 6, 7 .and 8, I employ insulating material to which the Opposite sides of the panel may be secured bymeans of nails. For such members I prefer to use resilient asbestos board, made by mixing the ingredients thereof and compacting the. mixture into stanchion shape By using such material for the spacing and^ frame members, I am enabled to iorm a wall securing the opposed wall sec- 1, 3 `and 2; 3 to such members by such cheap and' ordinary fastening means as nails lor screws. As walls or panels of this general character have been constructed heretofore, angle irons have been used for the purpose of spacing apart with a press.

and bracing the opposed sides or sections of not only because of the Weight, but because of. the expense incurred in securing the opposite sides of the alls to such angle iron members.'

In'Fig. 1, a corner of an oven or heattreating construction is shown. In making such corner, a special shape is given to the ends\of the adjacent wall sections Orpanels. It will be noted that the metal sheet 1 and the lining or the sheet 2a and lining or sheathing 3". The same is true as to the length of the sheet 1 and lining or sheathing 3 as compared with the length of the opposed sheet` 2 and lining or` sheathing 3. This enables the ends to be readily assembled into a corner, using vertical stanchions Gand 6a as a. comlposlte corner jolst. l

For the ordinary panels, other than corner panels, the two opposite sides 1, 3 and 2, 3 will be of the same lenth-see Fig. 3, and the metal covers 1 -and 2 and thesheathings 3 will be extended beyond their adjacent vertical frame members 6, and,v if.

necessary, in like manner beyond the uppermost and lowermost horizontal frame members '6. .The metal covering, however, will lbe extended still further, in order that a rolled or curled joint may be` formed be-r tween' adjacent panels, as indicated at 9.

A wall for the purposes specified may,l of course, bey built complete, in the saine manner as a single panel; or it may be,

This is objectionable,

sheathing '3EL are longer thanv builtl up from a number of panels, assembled in the manner indicated in Fig. 3 land With the corners formed as shown in Fig. 1.

A wall or panel constructed in accordance with my invention has the advantage that it is comparatively vcheap of production, is

light in weight thus minimizing the cost of transportation may be readily asseml bled on the job, and affords an effective heat insulation between the inner and outer surfaces of the wall. -The use of the particular kind of material for stanchions or spacing and framing members enables me to use cheap screws or nails for fastening the composite sides to the said braces or stanchior-s;

. and I am enabled toobtain all the necessary rigidity and insulation without the use of metal angles for the braces or stanchions. The air s ace between the stanchions and the sides o the partition or wall may be filled with any suitable insulating or nonconducting material, such as magnesium board, air-cell board, etc.

yHaving thus described my invention, what I claim is: f

1. A wall construction comprising ali intermediate frame work of resilient asbestos board having applied to opposite sides thereof 'wall' sections each having an external -sheet metal covering and an internal layer or sheathing of insulating material, the said wall sections being secured to thesaid frame,

formed of resilient asbestos board, and oplposed wall sectionssecured to said stanchions, each section comprising `an outer e sheet metal covering and an inner layerof -rality of horizontall insulating material,and screws or nails fastening the said wall sections to the said stanchions.

4. A wall construction comprising a pluand a plurality o vertically arranged stanchions constituting an intermediate intermediate arranged stanchions frame work, the said stanchions being formedpof insulating material capable of receiving and sustaining a screw, and opposed wall sections secured to said stanchions, each4 section comprising an outerl sheet metal covering and an inner layer of insulating material, and screws or nails astening the said wall sections tothe said stanchions.

5. A wall section or panel comprising upper, lower and side membersor stancliions of'resilient asbestos board, and opposed wall sections secured tothe said stanchions, each wall section comprising an external sheet metal covering andan inner insulating sheathing, the ends of the sheet metal coverings and of their cooperating sheathings projecting thereto and the ends of the coverings pro- `ecting beyond their respective sheathings, whereby the projecting metal endsoi1 one' beyond the stanchions adjacent,

such panel may be secured to the projecting metal ends of an adjacent panel.

' 6. A wall section or panel comprising upper and lower and side members or stanchions of insulating material, a wall section secured to thejsaid stancliions, said section comprising an external sheet metal covering and an in'ner insulating sheathing, the ends` of the sheet metal covering projecting beyondlthe ends of the sheathing, whereby the projecting metal ends ofone such panel may be secured to the projecting metal ends of an adjacent panel. Y

7. A wall section or panel comprising a marginal "frame work of resilient insulatf ing material, and a pair of yWall sections secured to such frame work andy comprising an outer sheet metal covering and an inner insulating sheathing,'the ends of the sheet metal coverings projecting beyond the ends of the sheathing and ybeyond the frame members adjacent thereto, of the sheathing of one panel are adapted to abutagainst the ends of the sheathing-of the adjacent panel and the sheet metal ends of said panels may be united vby a doublerolled bead.

8. A wall section or panel comprisingI a sheathing.

In testimony whereof, I hereunto aiiix 110 m si ature.
