Figure l isa vertical section taken parallel to `the front and back walls of an oven embodying the novel features of this invention;
Fig. 2. is a horizontal sectional view of such an oven showing a side portion thereof only;
Fig. 3 is a detail perspective view showing the front edge of one of the oven side walls, and disclosing how a rack member is engaged adjacent said edge;
Fig. 4 is a section on line 4-4 of Fig. l showing the mounting of a terminal block A in the oven.
In these views the reference characters l and 2`4 designate inner and outer double walls, between which is interposed heatinsulating material 3, such as asbestos or mineral'wool, the top. bottom, sides and ends of the oven being thus formed. The entire oven lining is formed of a unitary structure bv plates 4 either integrally formed or rigidly connected. At its front and back this lining is formed with outwardly projecting ribs or flanges 5 whereby the lining is held spaced from the adjacent wall 1, forming a dead air chamber 5a which constitutes a heat insulation supplementary to that designated by 3. Each wallv of the lining 4 furthermore carries an outstanding rib 6 extendingfrom front to back, reinforcing the central portion of said wall and preventing its being bent or dented. At their front edges the walls l and 2 are overlapped as indicated at 7 (see Fig. 3), and between said walls adjacent to their overlapped front edges a vertically extending metal'bar 8 is located. vAn angular sheet-metal strip comprising flanges 9 and 10 is also associated with the jfrpnt edge of each side wall, the flange 9 being' clamped between the over-4 Specication of Letters Patent.

comprises front and back vertical channell members 14 and ribbed horizontal members l5 rigidly connecting said channel members. The front channel member of each of said racks is formed with a forwardly extending flange 16 which, as is shown in Fig. 3, may be engaged between the edge portion of the flange 10 and the adjacent lining 4.
In installing said racks, they are first engaged at their front edges with the flanges l0 while in an angular relation to the adja-' cent side walls, as indicated in dash lines in Fig. 2. The racks are then swung into parallelism with the side walls, under which conditions the rear wall of the lining forms an abutment for said racks so that they cannot be removed until they have been again swung to an angular position relative to the adjacent side wall.
IVhen the above described construction is employed in an electric oven, upper and lower termina] blocks 17 and 18 may be mounted in the rear wall of the lining 4 and portions of the double walls l and 2 and the intermediate insulation may be cut away as indicated at 19 to allow said terminal blocks to project exteriorly of the oven.
IVhat we claim as our invention is- 1. In an oven, the combination with a side wall thereof. of a rack mounted against said side wall, interengaged flanges respectively formed upon one end of said rack and upon the adjacent side wall, and an abutment for the other end of said rack carried by the oven, the last-mentioned end being movable from the adjacent wall to effect disengagement of said flanges.
2. In an oven, the'combination with a side wall thereof, of a rack mounted against said side wall and abutting against a rear wall thereof, and interengaged fianges respectively formed upon the front edge of said rack and the adjacent wall, the rear j 'jendof'tlieraek'being frointhe 'a'd- Ajacent wall lto effect'Y disengagement ofi said flanges.`v I o j3; Infan oven, Vside Wall thereof, of' an angular strip assooven and theY combination With a ciated with the frontedge of said Wall hav- Ying a Hange clamped against said front edge and aY flange inwardlyextending `adjacent said Wall, and a rack mounted With-in the'V Voven adjacent said Wall formed vifith a Hangeadjacent its Jfront edge engaged beneath said` inwardly extending flange, therear ,endl of the .rack being movable from `the adjacent Wall to effect disengagement of said flanges.
