Thomas Henry Tregoning (c1833-1926) of the Redruth Foundry Co
c1833 Thomas Henry Tregoning born.
1926 February Died in Illogan.
1926 Obituary The death at Illogan last week of Mr. Thomas Henry Tregoning, at the age of ninety-three, robs Cornwall of an able engineer and draughtsman of the old school. He had spent all his life in the foundry trade in West Cornwall, which was his native place. About forty years ago he invented what is know as a the dipper wheel, which is still used in raising tin-bearing slimes from mine streams. Prior to its introduction the slime was lifted by boys with shovels and scoops. He was also associated with Michell's and Tregonning's patented pulveriser, from which the tube mill now in use developed. Both these appliances marked a distinct advance in mining methods, facilitating the work and making it more thorough. "Captain Tom", as Mr Tregonning was popularly known, had as a business colleague for some time Captain W. J. Hocking, of Camborne, but his last working days were spent as manager of the Redruth Foundry Co.
