OVEN CONSTRUCTION.
Appiieation sied july 26, 1928'. semi' No. 295,461.
This invention relates to an ovenk construci tion and more particularly to ovens to be used in connect-ion with electric stoves.
rThe principal. object of this invention is to provide an oven, the interior of which is formed of an integral sheet of metal and yet is so supported that the same will retain its shape in spite of the high temperature heat to which it is subjected. f
Another object is to construct an oven with the interior separate from the rest of the stove and yet will present a tight iitting construction which is far superior to the present oven7 and wherein the maximum amount of heat is retained.
Still another object is to provide a very rigid construction wherein allowance is made for expansion and contraction of the walls of the oven 'Without lessening the rigidity of the construction. p
Another object is to provide means whereby the interior ot the oven may be drawn toward the iear so that its front flange will be tightly held against the front face of the exterior of theloven.
Still another object is to provide a single means for securing the top of the oven in place. n
@ther objects will be disclosed in the specification and claims.
One of the problems always present in connection with the construction of ovens is to provide a structure that will retain the maximum of heat and at the same time allow for the expansion and contraction of the oven without losing its rigidity of construction which is essential. By making the interior of the oven separate, and of an in* tegral sheet of metal. there is less chance for the transmission of' heateither by radiation or conduction. By placing the securing means at the top and bottom and leaving the central portion free with a space behind for expansion and contraction, a very rigid construction is obtained without preventing the necessary expansion and contraction due to the high temperature.

AReferring to the drawings:
Numeral 1 designates an oven having an interior liner y2', with corrugations 3 in the form of shelves. The interior liner Q has a flange 1i which rests against the face offa front plate 5 of the oven l. At the rear of the interior liner 2 is secured a U-shaped member 6, which seatsin a U-shaped bar 7 secured to the oven frame 8. The U-shaped member 6 forms an integral part of a brace `80 member 8 whichv is secured at the top and` bottom of the interior liner 2 at 9 and 10. A screw threadedy member 7 passesy through the U-sliaped bar 7 and U-shaped member 6 securing the two together, and at the same timeT furnishiiignieans whereby the entire interior liner lmay be pulledback toward the rear causing thelflange 4to rest snugly against thefront plate 5y of the oven l.
This serves a second function of preventing the buckling outwardly of the. rear Lwall of the interior liner7 as the expansion is` limited'by the/brace memberfS. `TliezU-y shaped member Gis so `made that it is normally out ofengagemeiit with they back of the U-sliaped` bar 7 so as to allow for the` drawing back of the interior liner and at the saine time to allow for the expansion oi, the rear wall of the'interior liner in that `direction. The trame 8 with its side supports 10 and transverse member 7 provides a very rigid support. Openings 11 in frame 8 permit the oven terminal and contact clips 12 to extend therethrough. A rear plate 13 forms la cover plate for the oven 1. An oven cover'ltA having flanged edges 15 seats over the top andalong the side of the oven 1. A threaded screw 16 is .positioned centrally at the rear of the cover and aft-er passing through the cover 14. is threaded through a bar 17 until it seats against the back plate 13. Pressure exerted by the turning of the screw 16 Will draw the cover plate 14 to the rear, making a snug fit in the front and along the sides. Y
The space between the interior liner and t-he oven proper isiilled with the usual heat insulating material and by making the interior linerofy a yseparate piece of material spaced fromthe rest of the oven, the points of contact are'very few, thus cutting down the loss of heatby way of conduction- The front ofthe interior liner is held in place by the flanged which extends around the front face of' the oven and leaves the rest of the liner suspended from the oven until the lextremerear is reached where the U-shaped member 6 seats in the U-shaped bar 7.7, The corrugations 3 may be used to support different oven pans as well as to per mit the insertion of the heating unit at various heights according to thedesires of the operator.
The particular oven described herein presents one of the most eficient and durable :construct-ions of its kind, wherein vthe housewife gets the greatest heating yeiiciency and at the same time, the oven is so constructed that it. can be'v readily serviced.
Having thus described my invent-ion, what I claim is: l
1. An oven construction comprising an exterior casing, an interior liner supported by said exterior casing, a cross bar secured to saidf exterior casing, a supporting member secured to said interior liner, and means for securingsaid supporting member and said cross bar tol each other. Y
2." A11/.oven construction comprising an ex terior casing, an interior liner supported by said exterior casing, a cross bar secured to said exterior casing, a supporting member secured to said interior liner and` seated ink said cross bar, and means for adjustably securing said supporting Lmember and said cross bar to each other. f
3. An oven construction comprising an exterior casing, an interior liner supported by saidexteriorcas'ing, said interior liner having a langeextending around its outer face, a cross barsecured to said exterior l`casing,a supporting member secured to said interior liner, means for adjustably securing said supporting member and said cross bar to each other, said means drawing the flange on the interior liner against the outer face of said exterior casing.
4. An oven construction comprising an exterior casing, an interior liner supported by said exterior casing, a U-shaped cross bar f secured to said exterior casing, a supporting member secured to said interior liner and seated in said U-shaped cross bar and means for adjustably securing said supporting member and said cross-bar to each other.
5. An oven construction comprising an exterior casing, an interior liner supported by said exterior casing, a U-shaped cross bar secured to said exterior casing, a brace plate secured to said interior liner, said brace plate having side flanges and a U-shaped cross member formed integral with said brace plate, said U-shaped cross member seated in said U-shaped cross bar and means for adjustably securing said supporting member and said cross bar to each other.
6. an oven comprising an outer casing, having' its opposite ends yopen, an inner casing having only one end open and having a liange arrmndr its open end adapted to contact with and bey supported by one 01"' the open ends of the outer casing, a support extending across the other open end of the outer casing, and .means adjustable on said support to hold said inner casing supported in the outer casing with its fiange in contactA with the iirst named open end thereof.
7. 'An oven construction comprising an exterior casing, a cover plate to fit over the top of said casing, said cover plate having lianges extending around the top of said casing, means threadedly secured in4 one flange of said. cover plate, said means projecting through said lange and bearing against the said casing, whereby the cover plate will be drawn tight against said exterior casing.
8. Anoven construction comprising anexterior casing, an interior liner within said casing, a supporting member secured to said interior liner at top and bottom so as to leave the middle portion of said. liner free, means on saidcasing for supporting said member. l
9. An oven construction comprising an exterior casing, an interior liner supported by said exterior casing, a cross bar secured to said exterior casing, a supporting mein-ber` secured to said interior liner at top and bottom, and means for securing said supportingvinember and said cross bar to cach other.
In testimony whereof I afflix my, signature.
