"Whittlesea Mere - site of Appold Pump House"

The Whittlesea Mere pumping station was installed in 1851 using the newly invented Appold centrifugal pump, as shown atthe Greta Exhibition that year. It could pump 1,600 gallons per minute and lift water higher and faster than the scoop wheel. The plant was removed in 1877 to be replaced by a beam engine.

Water Mill at the victualing works at Red House, Deptford

A photograph made by Hallam Ashley of a technical drawing done by John Smeaton in the 18th century.

'Design for a Water Mill for His Majesty's Victualing Office Works at the Red House to be worked by water raised by a Steam Engine'. Transverse and Longitudinal Sections are drawn.
The yard at Deptford became the largest food-processing operation in England. It was largely rebuilt between 1774 and 1785.

Smeaton, John (1724-1792), engineer

Tuxford's steam portable traction engine

About 1839 a portable steam engine was produced, allowing the application of steam power in the fields beyond the confines of the farmyard. William Tuxford of Boston, Lincolnshire started manufacture of an engine built around a locomotive-style boiler.

"Tower Bridge - Valve Gear"

Tower Bridge is a combined bascule and suspension bridge in London built between 1886 and 1894. The bridge crosses the River Thames close to the Tower of London.
When it was built, Tower Bridge was the largest and most sophisticated bascule bridge ever completed. These bascules were operated by hydraulics, using steam to power the enormous pumping engines. The energy created was stored in six accumulators, as soon as power was required to lift the Bridge, it was always readily available. The accumulators fed the driving engines, which drove the bascules up and down. Despite the complexity of the system, the bascules only took about a minute to raise to their maximum angle of 86 degrees.
