To all whom it may concern:

Be it known that I, Lnwrs T. Wrnoox, a citizen of the United States, and a resident of Peekskilhin the county of VVestchester,

State of New York, have invented certain Ovens, of which the following is a specifica supplied from a point below theovemas when it is placed overgas or oil burners- Such ovens are usually provided wlth an open bottom and means for-causing the dis tribution of the heat so that the baking'or roasting of food therein will be effectively and uniformlydone. -They are also provided with doors having transparentportions through which the condition of the interior of the oven and the food in process of cooking may be observed Without opening the said door. It is to ovens of this class that the improvements relate. Their objects will appear from the followingspecification and the accompanying drawings referred to herein.

In the said drawings, Figure 1 is a front elevation of an oven embodying the improvements with a portion of the front broken away. Fig. 2 is a horizontal sectlon of the same on the line 22 ofFig. 1, looking in the direction indicated by the arrows in that figure. Fig. 3 is an enlarged vertical section on the line 3-3 of 2, looking in the direction indicated by the arrows in that figure.

The frame of the oven consists of four.

walls 1, 2, 3 and 4, a cover 5, and a bottom 6, the front Wall 1 is cut out to provide openings for the door and Windows and the bottom has a large central opening, through which heat passes from the burners to the interior, the edges of the metal around this opening being turned up to form a flange as shown at 7 (Fig. 1');

A substantially elliptical ring 8 is horizontally supported inside the oven on bosses 9, upon which rest the offset portions 10 0f the ring. Two sets of these bosses are provided on the interior surfaces of the inner walls 11, 12 and 13 of "the oven, one above the other, so that the ring 8 may be raised and lowered and supported thereby in lts upper or lower position. The top of'the BAKING-OVEN.

ing in the bottom of the oven so as to in tercept the heat rising-from the burners and cause it to pass up along the inner walls of the {ovon.- "The corners of the oven are angular and"the corners of the tray 14 are rounded, sothat a substantially triangularl space is left at the four corners and the dis--' tance between the corners and the tray is greater than the distance between-the tray and the walls at intermediate points; By this provision a larger opening for the up wardpassageof heated air is provided at the corners the points most distant from the burners, and a more uniform" distribution of the heat thus caused; The curvature ofthe corners ofthe tray, however, is on a shorter radius than that of the pans or dishes usually employed to hold food to be cooked, so thatthe edges of the said pans may come incontact with the walls without projecting materially beyond the tray. Such a pan is indicatedby the'dotted lines in Fig. 2, the inner circle of dotted lines representing the bottom ofthe'pan and the outer-circle representing the upper outer edge. "This pan is also shown at 17in Fig.

:1, in which it is shown to be flared from the bottom up and provided with an annular rim or flange 18." The primary objects ofthis provision are tooprevent theedges of the pan from interfering materiallywith the upwardspassageof heat and alsoto in-- sure that liquid overflowing fromthe pan will fall onth'e tray 14. Such liquid does not usually fall sheer from the rim of the pan but turns inwardly and drips therefrom inside the outer edge of the rim, and in most cases from thebottom of the pan, and as the bottom of the pan will always be Within the outer edges of the tray, the tray thus catches such drippings and protects the burners beneath it.

radiationfof heatqfrom the burners tothe medial part of the oven is thus interrupted to a sufiicient extent to prevent overheating and burning of the cooking food at this part of the oven.

The tray 1 1 is formed by stamping up a sheet of metal, then applying the false bottom and then turning over the edges of the metal to secure the edges of the false bottom. It is thus formed without the use ofsolder or other similar means for uniting the two parts.

The door 20 is hinged at 21 to the front wall 1 and is provided with a bracket 21, the lower end of which slides on the bail 22 fixed to the front wall, and theupper end of which is secured on the ring 23 of the door, so that the door will be supported thereby when opened and turned outward substantially at right angles to the front wall.

The upper edge of the door is provided with a latch consisting of a suitable knob on the outer side of the oven, and the tongues 25 and 26 secured to and turning with the knob. These tongues extend in opposite directions from the shank 27 of the knob and are. provided with bosses 28 and 29 respectively, which bear against the bead 30 and boss 31 of the front wall and oven respectively when the knobis turned to secure the door in its closed position, thereby insuring a tight closure of the door.

What I claim is:

1. A device of the character described, comprising an oven shell or casing composed of walls, a top, and a bottom, one wall being provided with a door opening and the bottom having an opening for the admission of heat, said ovenadapted to be placed upon suitable burners and said bottom opening extending over one or more burners, a door for opening and closing the door opening, a tray supported horizontally in the said oven below the upper part of the door opening, said tray covering and extending beyond the bottom opening and being spaced from the walls of said oven a greater distance at the corners of the even than at points intermediate said corners, the said spaces at the corners being less at their greatest width than one-fourth of the length of the shortest oven wall.

2. A device of the character described, comprising an oven shell or casing composed of walls, a top, and a bottom, one wall being provided with a door opening and the bottom having an opening for the admission of heat, said oven adapted to be placed upon suitable burners and said bottom opening extending over one or more burners, a door for opening and closing the door opening, a tray supported horizontally in the said oven below the upper part of the door opening, said tray covering and extending beyond the bottom opening and being spaced from the walls of said oven a greater distance at the corners of the oven than at points intermediate said corners, the said spaces at the corners being less at their greatest width than one-fourth of the length of the shortest oven wall, and the corners of said tray being curved on a radius greater than the greatest width of said space.

3. A device of the character described, comprising anoven shell or casing composed of walls, a top, and a bottom, one wall being provided with a door opening and the bottom having an opening for the admission of heat, said oven adapted to be placed upon suitable burners and said bottom opening extending over one or more burners, a door for opening and closing the door opening, a tray supported horizontally in the said oven below the upper part of the door opening, said tray covering and extending beyond the bottom opening and being spaced from the walls of said oven a greater distance at the corners of the oven than at points intermediate said corners, the said spaces at the corners being less at their greatest width thanone-fourth of the length of the shortest oven wall, and spacing members supporting said tray from said oven walls at the back and ends of the oven.

Witness my hand this 20th day of June, 1916, at the city of New York, in the county and State of New York.
