Built in 1893, this giant 250 ft diameter wheel was a remarkably bold undertaking. It was followed by large examples made overseas, each having somewhat different design philosophies, and posing different problems during construction.
The rim of the wheel was suspended from the hub by steel spokes of 2" diameter. There were 144 spokes.
The wheel was chain-driven, powered by a two cylinder horizontal steam engine made by William Tod & Co of Youngstown, Ohio.
