1781 Thomas and Robert Ransome advertised parts for clock makers, at terms equal to those from London and Birmingham makers
1785 The company, known as Ransome and Co, had been founded by Robert Ransome, an ironfounder in Norwich.
1785 Took out a patent for cast-iron ploughshares.
1786 Joshua Bullen and Co acquired the shop and stock of Ransome and Co, Market Place, Norwich. The Ransome patent cast iron plough share was advertised
1789 The business Ransome and Co moved to Ipswich.
1803 Robert was responsible for one of the important developments in ploughs. This was the chilling process, whereby the underside of the share was made extra hard, while the upper part remained soft and tough. The upper part thus wore away faster than the lower, so that a sharp cutting edge was maintained and less draught was required.
1804 Ransome and Son, in Ipswich, and Ransome and Co, in Yarmouth, advertised new, improved cast iron plough shares under the patent obtained by R. Ransome
1805 The partnership of Robert Ransome, James Rumbelow and James Ransome of Great Yarmouth, under the firm of Ransome and Co, ironfounders, was dissolved; the business was carried on by James Rumbelow and James Ransome as James Ransome and Co
In 1808 Robert Ransome took out a patent for the manufacture of interchangeable plough parts.
