COOKING-STOVE.

Specification of Letters Patent No. 20,783, dated June 29, 1858.

1 '0 all whom it may concern:

Be it known that I, SILAs T. SAVAGE, of the city of Albany, State of New York, have invented a new and useful Improvement in the Construction of Cooking-Stoves Intended to be Heated by Bituminous Coal; and I declare the following specification, with the drawings hereto annexed as part of the same, to be a full and perfect description thereof.

Figure 1 represents in profile an elevated oven stove with the right hand side plates removed from the oven and that part of the stove (from A to B) which lies underneath the oven, in order to show my improvement. Fig. 2 represents in perspective that part of the stove itself from A to B, represented in profile section in Fig. 1.

Similar letters in both figures denote the same parts of the apparatus.

The object of my invention is to permit the use of bituminous coal to effect the heating of the oven, without the consequence of fouling the flue, surrounding it, with the fuliginous matter passing over in the smoke of that kind of coal.

In the drawing the oven A is represented in the usual form surrounded with the hollow chamber or flue B, B, and standing on the top plate of the stove. In the usual arrangement the flame and smoke pass through an opening in that top plate directly into the fines B, B. WVhen using anthracite coal no soot can form within the fiues, and even when wood is employed as fuel if it be in good condition soot will accumulate slowly in the fines; but when bituminous coal is used soot gathers with great rapidity chok ing the flue, and injuring by its coating the conducting power of the walls of the oven. In fact so great is this clogging with soot as to make the use of said coal almost an impossibility with oven stoves. To enable me to obviate this evil, I dispense with the current of flame, &c., through the oven by employing the following apparatus. Within the space C, C, C, O, occupied by the oven upon the stove, tubes t, t, t, are inserted ex tending between the upper and lower plates of the stove, and opening at the top into the oven flue, and at the bottom into the open air. It is manifest that the air which enters into the tubes t, t, t, will be heated by the flame passing through the stove; ascend into the fiues B, B, and circulate around the oven. The flue B can be closed at E, by a partition and an opening fitted with a register made in the outer wall of the oven at G for the exit of the hot air; or an opening made in the top of the flue, with both sides of the flue left free for the air to pass up on both sides of the oven will accomplish the same purpose.

The operation of my improvement is the communication of the heat from the fuel to a current of air, which shall transmit it to the walls of the oven free from fuliginous matter.

I do not claim the employment of hot-air to heat an oven, but

I claim:

The arrangement of air tubes across the main flue of a cooking stove, for the purpose of receiving and transmitting the caloric of the fuel, to the walls of an oven by a current of heated air, substantially as set forth in the Within specification.

S. T. SAVAGE.
