UNITED STATES PATENT OFFICE.

JOSEPH LEEDS, OF PHILADELPHIA, PENNSYLVANIA.

COOKING-STOVE.

Specification of Letters Patent No. 10,716, dated March 28, 1854.

T all whom it may concern:

Be it known that I, JOSEPH LEEDS, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Cooking Stoves; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part thereof, in which Figure 1, represents a side elevation, Fig. 2, represents a longitudinal vertical section, and Fig. 3, represents a top view, with the top plate removed.

Similar letters in the several figures denote like parts.

The nature of my invention consists in forming the fire box or chamber of a series of vertical pipes or tubes, through which air passes, from a receiving air chamber underneath, which is entirely separated from the ash box, and becomes highly heated, and passes up underneath the top plate, and around the oven for cooking or baking purposes. And in so arranging the oven, into which hot air may be introduced if required, as that none of its sides or plates shall be in contact with the heated products of combustion, but be surrounded by hot air, by which means the most perfect regulation of heat maybe kept therein.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with reference to the drawin air chamber A, suitably provided with registers B, is formed underneath the front of the stove, into which air may be received from the room in which the stove is to stand or from any other place. Above this chamber A, is the ash box C, so arranged as to be entirely separate from the chamber A, the draft for supplying the fire being taken in through the ash box, from the hearth as it were of the stove. The fire box D, is ar ranged over the ash box, and is composed of a series of tubes or pipes E, which connect the chamber A, with a chamber F, above the fire. As the tubes E, are in immediate contact with the fire, and expose a great deal of surface to the fire, the air in passing through them becomes highly heated, and by impinging upon the plates which are in immediate contact with the fire or heated products of combustion, continues to be heated during its entire" passage under the top plate and around the oven.

The red arrows denote the passage of the gases through the stove, the blue arrows the air passages, and the black arrows the passage for conveying off the fine ashes when raking the stove.

The baking oven G, as before mentioned, is surrounded on five of its sides (the door H, forming the sixth side) by the hot air passage. In the bottom of the oven is a register a, for admitting hot air into the oven, and on top of the oven another register 6, for allowing the air, 'ases, &c., thrown off in roasting meats or other articles, to pass by means of the flue 0, intothe exit pipe (Z. By surrounding the oven with hot air, together with the registers for admitting if required, or escaping the air, the: most perfect regularity of temperature may be preserved, which is not the case when a portion of the oven plates are in contact with the heated gases, and another portion in contact with heated air only. done, when all the sides of the oven are in contact with the heated products, as the side remotest from thefire will be cold, when compared with the side which first receives the heat.

There is an opening 6, Fig. 2, from the hot air passage leading into a separate flue f, from whence if it is desired to use the hot air for any other purpose, it may be taken. But if not used, the flue f, may terminate, in the smoke passage (Z as represented in the drawing, and aid the draft of the stove. The chamber F, Fig. 2, above the fire box is enlarged, by moving the plate k, which is over the fire, as low down next the fire, as can be done with safety, so that said chamber is a depository of hotair further heated by the plate h, immediately over the fire.

I have represented the fire box as being square and composed of a. series of tubes or pipes. It may be round, oval or other shape, and the intention is to cast it in one piece or in segments, when it might have the same series of openings, and yet not be called tubes. Of course such a construction would be embraced in my plan. When made of wrought tubes, if found essential or economical to do so they can be riveted in to the top and bottom plates, after the manner of tubes or flues in boilers.

Other modifications of the stove might be Neither'can it be made involving the general principle herein described. Among them may be mentioned the carrying of the ash dust, which as here represented, is conveyed up in one of the tubes or pipes forming the fire box. It may be carried immediately back into the gas flue, and the pipe or tube used for heating air in.

Having thus fully described the nature of my invention, What I claim therein as new and desire to secure by Letters Patent, is

1. A fire box, formed or composed of a series of vertical tubes, through Which air JOSEPH LEEDS.
