steam hammer

Another man of science, James Nasmyth, the inventor of the steam-hammer, had a similar happy experience.

It was like killing a butterfly with a steam hammer, to loose so much vengeance against this frail piece of china.

The invention of the steam-hammer was the result of necessity.

This is particularly noticeable in steam hammer pistons, propeller shafts, and railroad axles.

The piles were driven with a Cram steam hammer weighing two tons, in a frame weighing also two tons.
