It further consists in so forming the lower part of the oven as to provide an air space, the top of which is level with the door when in open position. It further consists in providing an oven with a foraminous shelf which will be level with the door whenthat is opened an'dialso level with the top of the air space in the bot tom of the oven. n In theaccompanying drawings Figure '1 is a vertical section in perspective of this improved stove. Fig. 2-is a vertical section of the side wall at and just above the line of the burners.

Similar reference characters refer to like parts in'both views. i

This stove is' formed by mounting. the baking oven 1 above the broiling chamber 2 so that the same burners will answer for both. M The back of the stove is preferably formed of plates 3 and 4 which may be. continuous from the bottom of the broiling chamber to the top of the oven. The bottom of the broiling chamber is preferably formed of two plates'5 and 6 and plates 7 and 8 separate the oven from the broiling chamber, between which plates may be a layer 11 of asbestos, or mineral wool, although a simple air space maybe found sufficient. The air spaces between these several pairs of plates may be sealed'or not as desired. The sides of the oven and broili i ofjl iette I 113g seat...

From this space between the plates 1 19v and 21 the air and gases will pass up into the chimney 24. It will thus be seen that the burners 14 are used for both the broiling j chamberandthe oven, for either or for both at the same time.

This results in anair space between the shelf 25 and the bottom plate 7 of the oven," which is of great value as'hot air will remain undisturbed below the shelf 25 for a considerable period of time after the door 28 is opened. p I

" It will be observed that the walls sur rounding this air space between the shelf 25v and the bottom 7 are entirely imperforate and that there is no opportunity for transverse drafts of air in thisair space. Where such drafts are possible, an amount of cold air accumulates below the shelf .25 and re- I f mains there fora considerable period of time, being unaffected to a great extent by the hot air entering through the side opening 16. By preventing any circulation of air below the shelf '25, a very much more effective oven is produced. ,The location of and other flour products.
