IM PROVED GS' COOKING-STOVE.

Specification forming part of Letters Patent No. 47,650, dated May 9, 1865; antedated April '26, 1865.

To all whom, t may concern:

Be it known that l, EDWlN A. LELAND, of 117 Broome street, in the city, county, and State of New York, have invented a new and useful Improvement in GasStoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figures l and 2 are vertical sections at right angles to each other of a stove constructed according to my invent-ion. Fig. 3 is a plan of the same with the lids of the boiler-holes removed.

Similar letters ot' reference indicate corresponding parts in the several figures.

This invention relates to gas-stoves for cooking purposes; and it consists in a novel arrangement of burners and heating-passages, and novel form of the oven, to provide for the heating of the oven at the bottom, sides, and top, and for the use of waste heat from the oven-heating burner or burners, for boiling and other cooking operations which cau be performed on the top of the stove.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A is the outer portion ofthe stove, consisting of a box of sheet or cast iron of parallelopipedal or other convenient form. 'lhe oven 'B extends from back to front of this box, but

has spaces a b b and c (see Fig. 1) between its bottom, sides, and top and the bottom, sides, and top of the box, such spaces serving as lues and communicating with a chimney, z', on the top of the stove. rlhe upper portions of the sides of the oven are set in, as shown at d e in Fig. l, to make room for the upper burners, ff, which are used for boiling and other cooking operations that are performed on the top of the stove. This setting in of the upper part of the sides of the oven also permits the gas andheat from one or more burners, g, arranged below the oven, to act in a downward direction through the portions d d upon the contents of the lower part of the oven.

The several burners f f and y may be of any kind suitable for heating purposes, provided they are open at the bottom for the free passage of air through them. The upper burners f fare each situated directly under one of the holes Z l, provided in the top of the stove for the reception of the kettles, boilers, and other utensils, and directly over the portions d d of the oven, and the bottom of each ot said burners is set into one of two horizontal partition-plates, It h, which are placed across the spaces b b', between the upright upper portions, e e, of the oven and the sides ofthe outer portion of the stove, and at a short distance above the horizontal portion d of the oven. The only outlet from the space b below the plate It is through the burners ff. The oven-heating burner gis situated directly under the middle of the oven. The several burners are supplied by branch pipes j lo k t from the service .pipe n.

The branches 7c k, which supply the upper burners, f f, are furnished with separate (oaks p p, to provide for shutting off the gas from either or all of those burners without affecting the supply to the lower or oven heating burner, g.

When the stove is used for baking only, the gas is shut oft' from the burners f f' and only supplied to the burner g. The products of the combustion, together with any undecomposed air which passes through the latter burner, circulate laterally in opposite directions through the space or flue ct under the oven, and thence upward through the spaces or iues b b at the sides of the oven over the parts d d of the oven, and through the burners f f, whence they pass through the space or flue o, over the top of the oven to the central chimney, fi. These heated products not only heat the whole of the bottom, sides, and top ot' the oven, but the horizontal portions d d, from which heat is radiated downward onto the contents of the lower part ot' the oven, and hence all the said contents are heated both at the bottom, top, and sides.

For boiling or other cooking operations on the top ot' the stove, the upper burners may be used while the lower or oven-heating burner is in. use, the air necessary for combustion ou the upper burners being supplied through the lower one and through the fines ct a b b in a heated state.

The supply of air through the oven-heating burner may beregulated either by a damper below or by one in the chimney,g, so that it 1. The employment in a gas cooking-stoveV of one or more burners arranged directly un-V der the oven, in combination with `tlues below, Y

at the sides, and on the top of the oven, substantially as herein specified.

2. Incombination with the burners under the oyen, and the iiues under and at the sides thereof, the setting-in of the upper part ofthe oven, substantially as shown at d e in Fig. 2, whereby the heat is enabled to be radiated downward onto the contents of the lower part ot' the oven, as herein set forth.

3. The employment of a system of burners so applied in the lower and upper parts of a gas cooking stove containing an oven that the products of combustion from the lower burn er 4or burners pass through the upper burner or burners, and the latter is or are supplied with air through the former, substantially as herein specified.

4. The arrangement of the upper burners and the partition h in relation to each other and to the set in upper portions, d e, of the sides of the oven, substantially as herein described, whereby the products of combustion from the lower burner are caused to pass over the horizontal parts d ot' the said set in p0rtions, and so as to produce a downward radia tion of heat on the contents of the lower part of the oven, as herein set forth.
