The Whitebread Engine, the Earliest Surviving Rotative Steam Engine Built by Boulton & Watt

1785

The Whitbread Engine, designed by mechanical engineer James Watt  and manufactured for Boulton and Watt of Birmingham for installation in the Whitbread brewery in London in 1785, is one of the first rotative steam engines ever built, and is the oldest surviving. A rotative engine is a type of beam engine where the reciprocating motion of the beam is converted to rotary motion, producing a continuous power source suitable for driving machinery.

On decommissioning in 1887 the Whitbread Engine was sent to Australia's Powerhouse Museum (then known as the Technological, Industrial and Sanitary Museum) and has since been restored to full working order.
