Sun and planet gear

Sun and planet gear

A blog post from Helena Wee on her new animation:

The animation I am making for Canalology is inspired in part by Tottenham’s Markfield Beam Engine. This is a compound rotative type of engine built by Wood Brothers of Yorkshire between 1886 and 1888. It is the only surviving eight column engine still in situ, and the last engine produced by Wood Brothers. The mechanism evolved from the James Watt patented sun and planet gear, although this was originally said to have been invented by Scottish inventor William Murdoch who happened to be working for Watt at the time.

It is a living, working example of Victorian machinery and represented the height of scientific and technological progress when it was built. When running at sixteen revolutions a minute, each of its two pumps could move two million gallons of water a day.

Orbital movements within my animation will reflect the movements of the beam engine.
