He afterward cleans
out the crucible, prepares the bed of sand and charcoal, fills with
charcoal, and then passes to the next, and so on.
[Illustration: FIG. 5.--REHEATING FURNACE.]
_Trip Hammer_.--The workman at the hammer takes the bloom from the hands
of the assistant and shingles it under the head. Then he begins to give
it shape, bringing it to the state shown at c, in Fig. 7. The assistant
then brings him another bloom and takes the one that has been shingled
to the reheating furnace, where he heats but one of its extremities.
When the four blooms have been shingled, the workman takes up the first
and begins to draw out one of its extremities, which he afterward cools
in water and uses as a handle for finishing the work, d. Then he reheats
the other extremity, and, after drawing it out as he did the other,
obtains a bar of finished iron which he doubles, as shown at e, to thus
deliver to the trade.

One of these bars weighs from 11 to 12 kilogrammes.
