MPROVEM ENT lN GAS-STOVES.

Specification forming pa t ot'Lctters Patent No. 441,372, dated SeptcniberQO, 1864.

To all whom it may concern.-

Be it known that I, EDWIN A. LELAND, of the city, county,and State of New York, have invented a new and useful Improvement in Gas-Stoves and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1. is a vertical section of a stove with my improvement. Fig. is a horizantal section of the same.

Similar letters of reference indicate corresponding parts in both figures.

This invention relates to gas-stoves for cooking purposes.

It consists, firstly, in the construction of th; t part of the stove directly over the gasburner with two plates, having a space betwr en them, the upper plate having holes for the bottoms of the boilers, kettles, or other cooking vessels or utensils, and the lower one having corresponding or opposite holes by which the fiame and heated products (f combustion are concentrated under and around the bottoms of the said vessels or utensils, and caused to act thereon with better ett'ect than in tle stoves heretofore in use.

It also consists in the employment, in combination with the said plates and with an oven arranged in rear of the gas-burners,of a desceudingtlue, which conveys the heated products of combustion downward in front ot'the oven to a fine below the same, whence the said products'pass through a sheet-flue under the oven, thence vertical y upward through a sheet-flue behind the oven, and forward through a sheet-flue over the same, thereby giving the said products a circulation entirely around the oven, and heating the same more perfectly and economically than is done in other gas-stoves.

To enable others to make and use my invention, I will proceed to describe it with reference to the drawings.

The form which I usually adopt for a cooking-stove in carrying out my invention is substantially like that of the cooking-stoves employed for the use of coal and wood as fuel, the burner or burners A being arranged in a box, B,.arranged like the fire box of such stoves, and supplied with air through numerous orifices a ((1 below and in front. The burners may be of any construction adapted for heating purposes. The top of this box B is composed of two horizontal plates, 0 d, arranged at a short distance apart, to form a space, I), between them, the upper plate, 0, having holes 6 provided in it for the boilers or other utensils, and the lower one, (I, having holes f provided in it of a size nearly equal to c and opposite thereto.

The burners A are arranged some distance below the plate at and concentric therewith. The heated products of combustion from these burners have to pass off through these holes and into the space I), and in so doing are concentrated under and around the bottoms of the boilers or other utensils and caused to act thereon with great efi'ect. As the boilers or other utensils fit closely over or around the holes, the products of combustion are temporarily confined within the space I) and under the cooking utensils before escaping by the flue, but prevented from escaping through the holes 0 0 into the apartment.

0 is the oven, arranged in rear of the firebox, as in most cooking-stoves in which coal or wood are used as fuel. D is the descending flue, arranged in rear of the box B, bctween it and the oven, extending all across the stove, and forming a'downward communication from the space 1) between the plates 0 d to a sheetflue, E, under-the oven-the latter flue extending the whole length and width of the oven. Any upward draft from the space I) is prevented by means of a partition or damper, 9, above the flue D, the said partition being formed by a continuation of the plate 0 or otherwise. The flue E communicates with a vertical sheet-fine, F, at the back of the oven, extending the whole width and depth thereof, and this flue I communicates with a sheet-flue, G, which covers the whole surface of the top of;the oven,aud on the front of which is the chimney H. The circulation of 'the heated products of combustion from the space I) is down the flue D, thence along the flue E, thence up the flue F, and thence forward along the flue G to the chimney, and in this way the oven is heated all over the front, back, bottom, and top.

What I claim as my invention, and desire bustion under the cooking utensils and conto secure by Letters Patent, is-

Yey them to the flue provided for the purpose,

1. The construction of that part of the substantially as herein described.

stove over the gas burners of two plates, 0 and d, with a space, 1), between them, the upper plate, 0, having holes provided init for the boilers or other utensils and the lower one having corresponding or opposite holes for the concentration of the products of combustion under and around the bottoms of the said utensils, and the space 1) between them servin g to temporarily confine the products of com- 2. The descending flue D in combination with the said plates 0 d, the space I), the box 13, containing the gas-burners, and the oven 0, substantially as and for the purpose here in described.
