If you take a peek at the 1881 census, living at “Fairfield” in Thurlow Park Road, near West Dulwich Station was Arthur Ashwell and his family. Living so close to the station was very convenient for travelling across south London and, it was on one of these journeys that Arthur was travelling between Herne Hill and London, when an idea struck him.
Although some of the trains had toilets on board, one never knew whether or not it was occupied. Arthur’s bright idea was to create a “vacant/engaged” toilet lock so as to avoid potentially embarrassing situations.
Therefore, it was today, 17th February, back in 1883, that Arthur patented his lock, which incorporated a rotating disk indicating whether or not the facilities were being used.
