As mining became more important and the mines ran deeper
into the ground the means by which water could be removed
became more pressing. In 1712 Thomas Newcomen and his
assistant developed the first successful engine near Dudley
Castle in Tipton. So successful was the Newcomen engine
that it was soon deployed in countries around Europe and
beyond.
The Black Country Museum in Dudley has reconstructed the
Newcomen engine after much painstaking research. They
now have a full working replica of the 1712 engine.
The engine works by water in its boiler being heated by
a coal fire. The steam generated passes through a valve
into a large brass cylinder. Cold water is injected into
the cylinder condensing the steam and creating a vacuum
beneath the piston which pulls the beam down and causes
the pumps to move. Take a look at a diagram
of the engine.
