steam hammer

The haunted forge was in the smiths shed, adjoining the steam-hammer shop.

Father also received letters from Mr. Nasmyth, the inventor of the steam-hammer, on the same subject.

Then the steam-hammer shed, in which nothing but forging is done, was a flourishing place.

If you put him at the steam-hammer he is still at home; he will forge out an ingot or bloom with the best man on the ground.
