1872. Roots' Blower, made under licence by Thwaites and Carbutt
1854 The Roots brothers, Philander Higley Roots and Francis Marion Roots, established the Roots Woollen Mill alongside the Whitewater Canal (USA).
Their plan was to use the flow of water in the canal to power their mill, and as they attempted to design a better water wheel for the slow current, they discovered an unusual principle for moving air that became known as the Roots Positive Rotary Principle. This discovery led to the production of the Roots Blower patented in 1860.
The Roots brothers were probably unaware that the design was anticipated by George Jones of Birmingham, England, and registered in 1843.
