The process involves very laborious and long-continued hand-labor, and the current of air passingthrough the furnace lias to be regulated and changedas the process advances. Fig. 3993 gives an idea of the general appearance of the exte-rior of the furnace. The furnace-door is by the man in theforeground, who is holding the handle of the ball-trolley tocatch the ball or loup, which the furnace-man is just takingout of the iron chamber. .\ third man lifts the door by meansof the lever. Fig. .3994 shows a puddling-furnace of usual furnace-door is at L\ D, the door of the iron-chamber;K, the neck ; M, the stack. The iron boshes stand on pillars,and their exteriors are cooled by water introduced by tubesThe stack JWalso stands on pillars, so that it is not affected bythe tearing down of the neck. Fig. 3J9.» shows two forms of puddling-furnaces; a single-chambered and a double-chambered furnace. rUDDLINC^-FURNACE. 1817 PUGGING.
