9 C.L.GEHNHCH SECTI ONAL OVEN WALL Filed August 19, 1925 INVENTOR TORNEYS Patented July 27, 1926.
UNITED; STATES CHARLES L. GEHNRICH. OI ELMHUBST, NEW
TION OF NEW YORK.
PATENT OFFICE- DIRECT HEAT OVEN COMPANY, OF LONG ISLAND CII'Y YORK A COBPOBA- sacnomm-ovnx WALL.
This invention relates to sectional oven walls of that kind which are employed to build a sectional portable oven for baking japanned or enameled articles or other articles arranged in the oven.
An object of the invention is to provide an interlocking joint for uniting the vertical side walls and roof members adapted to obviate loss of heat, and at the same time by reason of the close fit between the abutting ends of the walls, dust is excluded from entering the oven or accumulating between the connecting walls.
Another object of the invention is to provide a closely fitted telescoping joint to allow for expansion and contraction in which the abutting ends are thoroughly insulated from each other so as to minimize loss of heat by open joints, crevices or otherwise.
Another object of the invention is to form the interlocking means of each member bending the sheets of metal of the inner and outer plates back upon themselves, thus forming a structure of great strength and rigidit The novel features of the invention are more fully described in the following specification and claims, reference being made to v the accompanying drawing in which Fig. 1 represents a perspective view showin a pair of the walls.
ig. 2 is a transverse section on a larger scale showing the two walls connected together.
In the drawing is shown two wall sections each section consisting of an outer plate 5 and an inner plate 6 of sheet metal, with a stufling 7 of non-heat conducting material such as asbestos packed between the plates. Both sections are similar with the exception, that one section has a groove 8 located adjacent the inner plate and a. tongue 9 extending from the outer or front plate; while the other section has the tongue projecting from theinner plate and the groove disposed in the other plate.
The groove of the first named section is formed b doubling the plate inwardly so as to pro uce two walls 10 parallel with the inner wall forming a groove. The inner wall 10 has a continuous member 11 bent at right angles to partly cover the end. The
tongue is formed b 0 end so as to parallel the plate, and it is provided with an integral end member 12 arranged at right angles to the tongue in order to partly cover the end of the wall. The end members 11 and 12 do not contact with each other and the conduction of heat by the metal is thus interrupted.
Behind strip of woven asbestos 14 to seal the end so as to prevent radiation of heatand leak age of the particles of asbestos filler. A strap 15 located at the back of the asbestos the end members is positioned a i strip and fastened to the end members secures the two plates together so as to hold them from spreadin apart.
When it is desire to join the two walls together both walls are moved towards each other with the tongues in line with the grooves then by exerting pressure on both ends the tongues will slide into the grooves b thereby "interlocking the two sections firmly together. By having the groove at the rear and the tongue at the front it facilitates the unification of the two walls and presents a strong construction to withstand lateral strain." As indicated in Fig. 1, the front wall of each section has an extended portion 16 made to interlock with and support a roof not shown.
Instead of having the tongue formed integral with the plate, recesses may be formed 1n each plate and the members secured together by an independent stri or ke fitting in the recess. It will also bo unde that the interlocking members or ton may be formed opposite each other on both plates of one member, and fit into two corresponding grooves adjacent the plates in one side 0 .the other member.
It will be understood that while only a single pair of wall members is shown, in practice the entire wall of the oven is constructed of a series of pairs of members and the oven may be of any desired size.
I claim 1. A sectional oven comprising a plurality of abutting wall sections s aced to include an insulating medium eac section in rstood gueseluding an inner and outer plate, a groove 1n one of the sections made by doubling one of the platesinwardly, and a tongue projecting from the other section for en 2. A sectional oven comprising a. plurality of abutting wall sections 5 acerl to include an insulating medium eac section ineluding an inner and outer plate, a groove in one of the sections made by doubling'and return bending one of the plates inwardly, and a tongue projecting from the other section for engagement with the groove formed by doubling one of the plates.
3. A sectional oven comprising a plurality of abutting wall sections spaced to include an insulating medium each section including an inner and outer plate, a groove in one of the sections made by doubling and return bending one of the plates inwardly, a tongue projecting from t e other section for engagement with the groove formed by doubling one of the plates, and end members extending at an angle from a wall of the groove and tongue.
4. A sectional oven comprising a plurality of abutting wall sections spaced to inclnde an insulating medium each section including an inner and outer plate, a groove in one of the sections made by doubling and return bending one of the plates inwardly, a tongue projecting from the other section for engagement with the groove formed by doubling one of the plates, and end members the ends of which do not contact extending at right angles from the inner wall of the groove and tongue.
5. A sectional oven comprising a plurality of abutting wall sections spaced to include an insulating medium each section including an inner and outer plate, a groove in one of the sections made by doubling and return bending one of the plates inwardly, a tongue projecting from the other section for engagement with the groove formed by doubling one of the plates, end members the ends of which do not contact extending atright angles from the inner wall of the groove and tongue, and a strip of non-heat conducting material fixed behind the end members.
6. A sectional oven comprising a pair of walls, each having an inner and outer plate spaced to include an insulating medium, a tongue and groove integral with the end portions of each plate, end members located at an angle to each plate, a strip of woven non-heat conducting material fixed behind the end members, and a strap disposed behind the strip secured to the end members.
In testimony whereof I have hereunto set my hand.
