The Easton & Amos Engine

This beam engine differs from the large Cornish beam engines in having one end of the beam connected to a crank to produce rotary motion. While it made the engine simpler to operate and maintain, the main drawback of this type of engine was that it was relatively expensive to install, requiring more engine parts and heavier foundations. It was popular for use in small, rural waterworks, where the huge capacity of a Cornish engine was not required. Rotative beam engines were also extensively used to drive mill and factory machinery.
