Man harnessed steam to do digging for him back in the days when
that form of power was still being developed for many kinds of
essential activities.

Excavation was the most demanding task faced by labor, in the
field of engineering construction, and steam was applied to this
before it went into any other phase of the building industry.

William S. Otis Patent Excavator No. Ill, 1841. Colored
lithograph by P. S. Duval; S. Rufus Mason, artist.

Working model of a steam pumper engine, 1873, built by Amoskeag
Manufacturing Company of Manchester, New Hampshire, for town of New
Brighton (Staten Island), New York.

William S. Otis–not to be confused with E. G. Otis of elevator
fame–designed a successful ‘steam shovel,’ illustrated
here. Its basic operation functions remain unchanged.

This drawing is dated 1841. It was shown at the Smithsonian
Institution in Washington, D.C., in an exhibit titled ‘Loose
the Mighty Power,’ which closed last January.
