Port Novo Iron Works and early Locomotive Experiments
Port Novo Iron Works
In c.1830 a Mr Heath, then Agent for the East India Company (EIC) proposed the manufacture of iron based on the mineral deposits of magnetic oxide near Salem [1].
Following trials the Mr Heath formed a Company with works at Porto Novo on the Coromandel Coast at the mouth of the Vellur River to produce high quality manganese iron [1].
The ores were prepared near Salem and conveyed by water to Porto Novo. The charcoal for the works was obtained from the extensive jungle at the mouth of the Coleroon River[1].
The Works thus became the first Iron Works in India [2].
After three years, in which Heath’s Iron Works produced pig iron of the highest quality, yet remained unprofitable, the company was saved from bankruptcy by an advance from the Madras Presidency, who renamed the works ‘The Indian Iron and Steel Company’. Following further financial difficulties the Madras Presidency intervened again in 1853, at which time the company was reinstated as ‘The East India Iron Company’, this fared little better and closed permanently in 1874 [3].
Locomotive Experiments
Captain Arthur Thomas Cotton of the Madras Engineers started experiments with steam engines in the middle of the 1830’s. He first took measurements from a static steam engine which was used to break rocks at the annicut (irrigation weir) being built across the Coleroon River about 35 miles down river from Trichinopoly. The machine had been built as an experiment and operated at a low pressure of 30lb/ft. It was effective and raised the hammer 30 times a minute and gave an power output of about 1:37th HP. The experiments carried out showed what happened when cylinders sizes were altered along with the orifice sizes [4]
With this information they arranged further experiments at the Port Novo Iron Works. On the 5th May 1838 they started and by 31st May they had the workings of a locomotive. This unit never ran on rails but was used to power a lathe. It was calculated that a locomotive would run up to 22.5 mph (35Km/h) [4].
These experiments were important in the developing the Red Hill Railroad at Chintadripet by Captain Arthur Thomas Cotton which was constructed in 1836 and opened 1837 for the conveying of hard laterite to be used as road-building material. It was the first railway in India.
