What I claim as my invention, and desire to secure by Letters Patent, is
1. A furnace comprising a combustionchamber and an overhead gas-inlet, arranged to introduce gas at a point intermediate between the ends of the furnace, and fines, ducts or passages constructed in the masonry of the furnace arranged to conduct the gas in opposite directions from the inlet to the combustion-chamber, and means for delivering the infiowing gas into one or the other of the fines, ducts or passages, which flues, ducts or passages are traversed solely by the combustible gas, as described, and for the purpose specified.
2. A furnace comprising a combustion chamber and an overhead gas-inl,et,'arranged at substantially the center of the length of the furnace, and fines, ducts or passages constructed in the masonry of the furnace arranged to conduct the gas in opposite directions from the inlet to the combustion-chamber, and means for diverting the inflowing gas into one or the other of the fines, ducts or passages, which fines, ducts or passages are traversed solely by the combustible gas, as described, and for the pnrpose'specified.
3. A furnace comprising a combustionchamber and a gas-inlet, arranged to introduce gas at a point intermediate between the ends of the furnace, and fines, ducts or passages arranged to conduct the gas in opposite directions from the inlet to the combustionchamber, said flues, ducts or passages communicating with ports which lead into the combustion-chamber, and which are arranged at intervals in the length of said combustionchamber, on either side of a line extending transversely through the middle of the furnace, and means for diverting the in flowing gas into one or the other of the flues, ducts or passages, which fines, ducts or passages are traversed solely by the combustible gas.
4. A furnace comprising a combustionchamber and an overhead gas-inlet, arranged to introduce gas'at a point intermediate between the ends of the furnace,and fines, d. nets or passages constructed in the masonry of the furnace arranged to conduct the gas-in opposite directions from the inlet to the combustion-chamber, and means for divertingthe inflowing gas into one or the other of the fines, ducts or passages, which flnes, ducts or passages are traversed solely by the combustible gas, together with regenerative chambers in communication with the combustion-chamber at opposite ends of said combustion-chamber, and means for reversing the direction of flow of outgoing products of combustion and incoming air through the furnace, for the purpose specified.

7. A furnace comprising a combustionchamber, an overhead gas-inlet intermediate between the ends of the furnace, and a number of regenerative chambers, together with means for diverting the course of the gas and the air for its combustion so that the gas and air are supplied alternately in portions of the combustion-chamber lying on opposite sides of a transverse line extending through the middle of the furnace, and appropriate fines, ducts or passages constructed in the masonry of the furnace for conduction of the gas, and regenerative chambers communicating with the said combustion-chamber at opposite ends thereof, said regenerative chambers being so arranged that the air and the products of combustion may traverse them alternately, substantially as described.
