context_page_description: John Ramsbottom was an English mechanical engineer. Born in Todmorden, then on the county border of Yorkshire and Lancashire. Ramsbottom was the son of a steam cotton mill owner. He learned about steam engines, rebuilding his father's and also invented the weft fork 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.
