The Leeds Forge Company manufactured corrugated furnaces for marine steam engine boilers and pressed steel railway rolling stock.

Samson apprenticed with Smith, Beacock and Tannett of Victoria Foundry, Leeds, succeeded Fenton, Murray and Jackson, builders of rail locomotives.

The Corrugated Furnace consisted of an iron (later steel) tube that was heated and swaged (later rolled) under pressure to form corrugations, increasing the surface area of the tube and thus allowing a greater energy transfer from the heat source to the boiler while also providing additional resistance to boiler pressure.

[2] After the success of the corrugated furnace, Fox turned his attention to other products, and in 1887 exhibited in Newcastle[clarification needed][3] his flanged frame plate for railway rolling stock.

The construction technique, which used male and female dies in a hydraulic press, was very labor savings in comparison to hand-built timber cars.

In 1899 Fox sold his American operation to rival Charles T. Schoen, who went on to form the Pressed Steel Car Company.
