Who invented the adjustable spanner?

In many European countries (e.g. France, Germany, Spain and Italy) it is called an "English key" as it was invented in 1842 by the English engineer, Richard Clyburn. Improvements followed; on 22 September 1885, one Enoch Harris received US patent 326868 for his wrench that permitted both the jaw width and the angle of the handles to be adjusted and locked. Other countries, like Denmark and Israel, refer to it as a "Swedish key" as its invention has been attributed to the Swede, Johan Petter Johansson, who in 1891 received patent for an improved design of the adjustable spanner. Johansson's spanner was a further development on Clyburn's original "screw spanner". And in some countries (e.g. Hungary, Iran, Slovenia, Poland, Romania) it is called "French key".
