Abstract
An oven especially--but not exclusively--for baking French bread has a single loading opening which is closed by a principal door having a fill opening therein which, in turn, is closed by a series of small longitudinal, superimposed folding doors. One edge of each folding door covers the adjacent edge of the folding door immediately next to it. The small doors either pivot over an arc 180.degree. or slide laterally. The back of the oven may be equipped with a set of doors, such as the small doors. A gap separates the front edge of plates for supporting the bread and the plane of the interior side of the small doors. The plates are relatively thin, movable perforated sheets. The ends of a latch or hook-up bar may slide into supports on the stiles of the loading opening or be held in struts provided on each side of the small doors.
Claims8
An oven for baking food products, said oven comprising a single loading opening which is closed by a principal door with hinge means having a vertical pivot axis located adjacent an edge of said door, said principal door having a filling opening closed by a vertically aligned series of small longitudinal folding doors extending across the width of the principal door, off set hinge means for pivotally supporting an edge of each of the small longitudinal folding doors about 180.degree. toward the front and along a horizontal axis located forwardly of said door, the opposite edge of each of said folding doors covering in a practically sealed manner an adjacent edge of the folding door which is immediately next to it.
An oven for baking food products, said oven comprising a single loading opening closed by a vertically pivoted principal door having hinge means for providing pivot points located adjacent an edge of said principal door, said principal door having therein a filling opening closed by an aligned series of small longitudinally superimposed doors which extend across the width of the principal door a plate having extensions projecting therefrom, an off set hinge means pivotally coupled between said plate and said principal door, the extensions being located along one edge of each small door for covering in a practically sealed manner the adjoining edge of a neighboring small door which is immediately next to it when said small doors are closed, the perimeter of the said filling opening including at least part of an edge of a principal door.
An oven for baking food products, said oven comprising a single loading opening closed by a principal door having a hinge along one vertical edge thereof and further having therein a filling opening closed by an aligned series of small vertically pivoted longitudinal folding doors extending across the width of the principal door, an edge of each folding door covering in a practically sealed manner the space between it and the next adjacent neighboring door, the perimeter of the loading opening including at least part of an edge of the principal door, a cable extending through a channel adjacent said series of longitudinal folding doors, and hook-up bar means carried by said cable means latching said longitudinal folding doors.
