I'm trying to trace anybody who had ancestors who work for the Saxby & Farmer Signal Works. John Saxby worked for the London, Brighton and South Coast Railway which began in 1852. In 1856 Saxby took out a patent for a signal lamp that was linked to the railways point and manufactured his new signals in Brighton but left the railway in 1862, moved to Kilburn in London where he joined forces with John Stinson Farmer and opened a factory in what was then Kilburn Lane and later became Canterbury Road. The company was amalgamated with others in 1920 to form Westinghouse Brake and Saxby Signal Company. My Gt. Gt Grandfather was pattern maker until his death in May 1871 Michael
