Having Francis Richards return as the answer to who invented the door spring, is like Alan Shepherd coming back as the answer to who was the first man in space?
They have kindly now changed the answer to direct to a Wikipedia article on door closers (one I have an interest in editing) as the terms door spring and door closer are used interchangeably along with a number of other terms.
My logic was if the terms are used interchangeably and the term door spring was used as early as 1748 as I have pointed out elsewhere the google search cannot correctly return Francis Richards as the first person to invent the door spring, he only received an American patent in the early 1870's.
Since the above I have now noticed that when googling who invented the door closer Lewis (Louis) C. Norton is returned, taken from an article produced by LCN and The American Society of Locksmiths. I also respectfully consider this to be not as accurate as it might, as you can see below the word 'door closer' was used as early as 1850 when referring to George Beattie's door spring/door closer (even earlier uses of the term "door closer" do exist), so again how can Mr Norton be considered the first person to invent the door closer, door closer and door check being one in the same?
You can see in the rather gruesome news report of 1826 for example that door checks were mentioned long before Mr Norton turned his inventive mind to the problems at the Boston Church. Creative soul as he undoubtedly was, he should not, in my opinion, on a global search engine be returned in the number one slot for a search of who invented the door check either we have the Ovendon's for that as I have discussed previously. - https://www.midlandsfloorsprings.co.uk/blog/lewis-c-norton-and-the-first-door-check
