ding into each flue near its bottom. The external jacket of the furnace is filled with coalashes. A water-pan above the fire-pot is fed from an external communicating vessel. Hot-air furnace. Hot-air furnace. Hot-bed frame. The structure of sides and ends on which the sash of a hot-bed rest. Hot-blast. A blast of air heated previous to its introduction into the smelting-furnace. The process was invented by Nielson, of Glasgow, Scotland, and patented in 1828. In 1845, Budd patented in England the utilization of the heated gases from the blastfurnace for heating the blast. By means of the hot-blast, anthracite coals were used successfully in smelting iron in Wales, in 1837, and at Mauch Chunk, Pennsylvania, in 1838, 1839. Hot-blast Fur′nace. The temperature of the air, previous to its being thrown upon the charge in the furnace, is raised to about 600° in an outer chamber or in a series of pipes. These are variously arranged.

y used in blast-furnaces. In 1760 Smeaton erected at the Carron works the first large blowing cylinders, and shortly after Boulton and Watt supplied the steam-engines by which the blowers were driven. Peter Onions, in his patent of 1783, described the rationale of the puddling process; and Henry Cort, of Gosport, in 1784, made it practicable, and added grooved rolls, by which the puddled bar was drawn. Neilson, of Glasgow, introduced the hot blast in 1828. Aubulot, in France, in 1811, and Budd, in England, in 1845, heated the blast by the escaping hot gases of the blast-furnace. The Calder works, in 1831, demonstrated the needlessness of coking when hot blast is employed. Experiments in smelting with anthracite coal were tried at Mauch Chunk in 1820, in France in 1827, and in Wales successfully by the aid of Neilson's hot-blast ovens in 1837. The experiment at Mauch Chunk was repeated, with the addition of the hot blast, in 1838, 1839, and succeeded in producing about two tons

and the blowing engines, driven by manual, horse, or ox power, were henceforth operated by steam-engines. The dimension of the blast apparatus was increased from time to time, and about 1760 coke was commonly used in smelting. In 1760 Smeaton erected at the Carron Works the first large blowing cylinders, and shortly afterward Boulton and Watt supplied the steam-engines by which the blowers were driven. Neilson, of Glasgow, introduced the hot blast in 1828. Aubulos, in France, in 1811, and Budd, in England, in 1845, heated the blast by the escaping hot gases of the blast-furnace. In the smelting of iron four tons weight of gaseous products are thrown off into the air for each ton of iron produced. See under iron; malleable iron; and other titles, for which see list under metallurgy. As a means of estimating by comparison the value of the hot blast, some facts may be mentioned. Mushet states that at the Clyde Iron Works, before the introduction of the hot blast, the quantity o
