Figure 4 is a fragmentalsectional detail illustratingthe joint between the bottom and the walls; Figure 5 is a'section taken through one corner of the area in a --plane passing through the tenement the-"corner piece; Figure 6 isa sectioir take'n tin-a plane which is shaded from the etting planed Figure 5; Figure 7 rs acperspect-ive diselesing the corner piece joined to one of the walls, parts being broken way; Figure 8 is a perspective wherein a modified tioiiier piece appears.

The oven forming the snbjectniitter of this application is made of metal throughout saving as otherwise designated, and includes a back 1 a front 2 sides 3 and a top may be, alluded to walls.

. T-hebttckhfithe front 2 and thesides The bottom ot theqoven is marked by the numeral-5'.

The body of {tlIBVOVB II comprises {an inner layer 6, the "layers *6 abutting at each corner of the oven as indicated by the j'reterence numeral 7 in Figures 5 and 6. Each wall inclucles'an outer layer 8 there being a space 9fbetwe eh the edges of the layers 18 at the corner of the oven. Between the layers 6 and .8151 packing 859i heated insulating ma- Iter-i l" i s-man. Verticallyfelongatedslots 1'1 are -fashioned inthe inner layers 6. Angular cbrner .pieces '12 ar'e preview,

:each corner piece including outer wings 14;

located at right angles to each other, the wings 14; bein'g'bent 'as 'at 15 to form inner flanges 16 lying againstthe inner surfaces of the wings 14', the flan gesrbeingjbent as at 17, to form lips 18 disposed parallel to the flanges 16, andspa-ced t-herefroinyas shown at 19. The lips 18,, a-r'eflnotche'd in their edges, as shown at 20 in F igure 7, to form bendable tongues '21-. Bendable tongues 22 are fashionedgon the upper endsof the outer wings 14 of the corner pieces 12.

i v, The inner-flanges 16 of the corner pieces 1:2 lie aj-gainst the outerlayers 8 of the walls, a's clearly shown in Figures 5 and 6', the walls extending into the space 19, between the inner flanges/16 and the lips 18'. The tongues 20 extend through the packing 10 and through the parts 11 in the inner layers 6 and are bent or clinched upon; the inner layers 6 as shown in Figure 7-. The tongues 22 "are bent downwardly over the upper edges of the outer layers 8', as indicated in Figure 7. It will be clear from the foregoing, that thev corn-er pieces 12 constitute a simple but efficient means for joining the walls :of the oven at the vertical corners thereoi. r I d, In Figure 8 of the drawings a inod ed fo' riiir of eoriiei piece is show-'11,. Icorner pie seeing of the eoiistiuetion hereinbefo'te aster-thee; swin er the fact that -a,t the 3 9 f i fi ir 'b w e he i fl' f '1? and 16 sockets 23 "are fashionedgthe sanle beingfadapted reacti rods in bolts i liich inhiy used for joining the-top audjthe bottom ofxthe oven to the walls, In Figure 8; parts hereinbefore described have been designated by numerals previously used, with the sufiix a;

Referring to Figure 4, the outer layersv 8 "panes if desired.

the sides and the back and is supplied with of the walls are extended as at across the lower edgesi'of thepacking 10 and the inner layers 6, and are provided with upstanding flanges 26 received within hookshaped beads 27 formed on the bottom 5, securing elements 28 passing through the parts 27, 26, 6, 10 and 8. The bottom' 5 may be supplied with an inverted funnel-shaped inlet 29, above which is disposed ahollow inverted conical deflector and shelf 30, the same being supported at 31 on the walls of the oven. A shelf 32 is located above the member and is mounted on the supports 33 carried by opposite walls of the oven, the shelf having depending portions 34, between which the supports 33 are located. Both of the parts 32 and 30 may be fashioned from a combination of metal and heat insulating material, if desired, as shown in Figure 3.

The top 4 comprises, as shown in Figure 2, an upper layer 35 and a lower layer 36, between which a heat insulatingpacking 37 is disposed. The'upper layer 35 has a depending flange 38 'overlapned on the outer surface of the outer layer 8 of each wall and extended downwardly to an outwardly projecting rib 39formed on the layer 8. The layer 36 of the top extends across the upper edge of the inner layer 6 of the wall and is provided with adepending flange 4O abutting against the inner surface of the outer layer 8 of the wall. If desired, the top and the bottom may be held in place by securing devices or bolts 41 located at the corners of the oven, as shown in Figure 5, although the use of these bolts is not insisted upon.

The front 2 of the oven is constructed like an opening 42 closed by a door 43, comprising an outer layer 44, an inner layer 45, and a packing 46' therebetween, the layers and 44 being connected about the periphery of the door as shown at 47 There is an opening 49 in the door, and the inner layer 45 and the packing 46 extend inwardly beyond the outer layer 44 to form a shoulder 48 against which abuts a pane 50 made of glass if desired, the periphery of the pane being engaged byan outer layer 44 as clearly shown in Figure 3. Atransparent pane 51 is locatedparallel to the pane 50 agasket 52 being interposed between the i A frame 53 isattached by securing devices 54, to both layers of the door, and "s supplied with a' hook-shaped flange ;bearing'- against theouten pane 5'1.

'Hinges 56 are secured to the door and to the 'front'2 as disclosed in Figure 1.

The-oven forming the subject'matteno f this application is simple in construction and strong and will maintain its shape even 7 under a high degree of, long-continued heat.
