Note: John Ramsbottom (b. 11 September 1814 – d. 20 May 1897) was an English mechanical engineer. he was born in Todmorden, then on the county border of Yorkshire and Lancashire. Ramsbottom was the son of a steam cotton mill owner. here he learned about steam engines, rebuilding his father's and also invented the weft fork (this has also been attributed to James Bullough) that enabled looms to be run at high speed. He also created many inventions for railways but his main legacy is the split metal piston ring, which he invented and later perfected. Virtually all reciprocating engines continue to use these today.

Ramsbotham became a member of the Institution of Civil Engineers in 1866. He was also president of the Institution of Mechanical Engineers in 1870 and 1871.
