ERAs'rUs W. ROGERS, or DURHAM, NORTH CAROLINA.

OVEN.

Application filed May 10,

To all whom t may concern.'

Beit known that I, ERAs'rUs NV. ROGERS, a citizen of the United States, residing at Durham, in the county ol' Durham and State of North Carolina, have invented a new and useful Oven, of which the following is a specification.

This invention relates to ovens especially designed for use in connection with gas stoves, oil stoves, and the like, one of the objects or the invention being to provide an oven which can be easily placed upon a stove, there being means for directing the hot gases from the stove into the side portions of the oven where they will flow, in sheets upwardly to a central longitudinal outlet formed in the top or the oven, said products or hot gases subsequently iiowing downwardly through the walls of the oven to outlets provided therefor.

A further object is to provide an oven I which, by evenly distributing the hot gases throughout the length thereof will insure uniform baking.

Another object is to provide means for delecting the hot gases to the inlet openings and from the outlet openings so as to enable the gases to ilow freely in the proper direction.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

In the accompanying drawings the preferred form or the invention has been shown.

In said drawings Figure l is a vertical longitudinal section through the oven, said section being taken on the dotted line indicated in Fig. 2.

Fig. 2 is a central transverse section through the oven.

Referring to the figures by characters of reference l designates the solid back wall or the ove-n and 2 designates the solid front wall to which is hingedly connected a door 3. The front wall 2 is provided with a large opening adapted to be closed by the door and connecting the front and back walls ot' the oven are inner and outer walls 4 and 5 respectively forming a space therebetween Specification of Letters Patent.

extending throughout the length of the oven from one side to the other of the topA of the oven and from the top to the bottom of the side walls. This space has been indicated at 6. The inner and outer walls 4 and 5 are mounted on an open base 7 which closes the space between the inner and outer walls at the lower end of said walls. The base 7 projects inwardly from the inner walls 4 to provide ledges 8 on which are mounted downwardly extending flanges 9 extending from the bottom 10 of the oven. Formed in this bottom close to each of the side walls 4 is a longitudinal series of apertures 11 and extending downwardly from the bottom l() between these series of apertures is a longitudinally extending deiector or spreader l2 the opposed side portions of which diverge upwardly toward the respective series of openings as shown particularly in F ig. 2.

Formed in the top of the inner wall 4 along the center thereof is a longitudinal outlet slot 13 and depending from the top or the outer wall 5 directly above this slot is a spreader or defiector 14 the opposed sides of which diverge upwardly as shown. Outlet openings l5 are formed in the outer walls 5 close to the base 7. Suitable supports 16 or shelves or the like can be arranged within the oven as shown.

It is to be understood that the oven herein described is to be placed on the top of a stove so that the hot products of combustion can pass upwardly into the space below the bottom 10 where they will be spread toward the two series of openings l1 and pass directly into the oven close to the inner walls 4. The hot products will thus travel upwardly in the oven and will pass outwardly, in the form of converging sheets through the opening 13 which extends continuously from one end to the other of the oven. As the hot products pass out through this opening they will be spread by the deflector or spreader 14 so as to pass in opposite directions into the space between the inner and outer walls 4 and 5 and then low downwardly between said walls to the outlets 15.

By providing a structure such as described the hot products oi combustion are distributed evenly' throughout the depth of the oven and the eiciency of the oven is greatly increased because the hot products, after leaving the oven, flow laterally and downwardly between the inner and outer walls,

thus maintaining the temperature in the oven at a higher' degree than would otherwise be possible.

What is claimed is:

' An oven including inner and outer side and top walls spaced apart to provide an air space therebetween, there being a central longitudinal outlet slot in the top of the inner wall and outlet openings in the lower portion of the outer wall, end walls connected to the inner and outer top and side walls, a base secured to the bottoms of the walls and having ledges extending inwardly i'rom the lower end of the inner side walls, an oven bottom having a longitudinal series of openings adjacent each side thereof,

flanges extending downwardly from the sides of the oven bottom and removablyv mounted on the ledges, a spreader extending longitudinally along therbottom face of the oven bottom and inclined upwardly and outwardly toward the openings in said oven bottom, and a spreader secured to the bottom face of the top of the outer walls and extending longitudinally thereof above the outlet opening in thetop of the inner wall.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of a witness.
