COOKING APPARATUS.

Specication of Letters Patent N o. 5,239, dated August 14, 1847.

To all whom t may concern.'

Be it known that I, BERNARD ANTOGNINI, of New Orleans, in the State of Louisiana, have'invented a new and Improved Mode of Cooking, which IA call Economical Cooking-Furnace; and I do hereby declare that the following is a full an exact description.

The nature of my invention consists in the making of furnaces employed for cooking.

The character of my invention consists in cooking promptly, ,wit-ha great economy of fuel, and with a great reduction of the expenses of instalment incurred for the different methods of cooking already known.

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

I constructmy furnace in the following way (see drawings) A, furnace of a square opening of 7 inches; B, furnace of a square opening of 8 inches; C, furnace of a round openinoP of 9%- inches in diameter; D, furnace of a square opening of 10 inches;fE, long furnace of a rectangularopening of 14 inches by 6 inches; each of those furnaces is established in the center of a plate of cast-iron which is aflixed by means of screws, thereby isolating each plate, which permits to supply the said plates separately when used up or damaged; F, shell (so called from its form) of cast iron, employed for roasting.` G, reflector made of tin which receives the piece which is to be roasted; H, H, H, iron plates isolating each of the furnaces A, B, C. I, iron plate, being the bottom of the system, resting on a plas tering K, which plastering K is supported by a floor L; M, 'oven warmed at-the same time by the furnaces D, E, and byk the shell F; N, ash pan made of iron plates, supported by two iron rods at a convenient height, in order that the ashes do not fall on what is cooked in the oven M; O, O, iron rods intended to isupport dishes of things to be cooked; P, P, P, doors of the furnaces A, B, C, by which doors the fire is revived or extinguished, and the ashes are extracted; R, large door of the oven M. This large door R bears a small one which is employed to overn or to extinguish the fire.

peration: The furnaces being loaded with the requisite quantity of charcoal a certain number of cooking pans are put on each furnace, in such way that each cooking the smoke.

pan receives the necessary quantity of fire. Of course thel number of cooking pans so placed on eachfurnace depends on the dimensions of the cooking pans. On the furynaces of; the dimensions given in this my specification (which dimensions are generally convenient) 5 cooking pans can be placed on each furnace; four on the furnacek and the other one supported by those four. By means of the door yof each furnace, the fire is increased if the cooking must be prompt, or diminished if the cooking must be slow; whichv effect is caused by the combined action of the door and of the iron plates H, H, H which isolate each furnace; that said action governing the air easily and surely for increasing or diminishing the fire.

The advantages of my furnaces are, the following: l, they can be employed anywhere, in open air or in a room without a chimney, without causing the nuisance of In this point they differ from` the cooking furnaces already known, which cannot be used'in a room unless that room has a chimney, or unless an apparatus be adapted to lead out the smoke. 2, they are easily portable, which gives' the power of -f cooking even Awhile traveling, for instance on a rail-road ror on la wagon. A two holes furnace can be transported by one man and cankcook for 8 persons. In that property of being easily portable, they differ from the.y

vfurnaces already known. 3, They can be very easily and economically repaired on account of thek separation ofeach cast-iron plate that bears each furnace; the cover or upper surface of my furnace being composed of several parts. In this point they dier from the cooking-furnaces already-95 known, because in the cooking furnaces already known theplate forming the upper surface is made of a single piece, and when that cover is broken or damaged in any place, a new whole cover must be made, 100 l which f is expensive, which large expense is avoided in my furnaces by supplying only theplate which is damaged. 4, the separation of each furnace by the plates H, H, H, l gives the power of cooking-rapidly in one 4105 furnace, and at the same time of cooking slowly in the next furnace. 5, their greatest advantage is the economy of fuel. With a given quantity of fuel my furnaces will f cook for 5 times more than any 'other cook- 110 K ing apparatus already known. The cooking being done, if any quantity of fuel remains that has. not been burnt, it will be preserved by shutting the door and covering the opening of,4 the furnace.` The expense of fuel necessary for the use of 5 furnaces and of the part called 9 shell, is 3 cents per hour, or cent for each furnace employed separately. Those furnaces offer also advantages of cleanness and of exemption from the dangers of fire.

What I claim as my invention and desirey to secure by Letters Patent are the following arts: y Y y 1. The division of the cover or upper surthe use of charcoal.
