Interesting Invention - The Monkey Wrench

According to some theories the monkey wrench was invented by London born blacksmith Charles Moncke.

(A monkey wrench is a tool which has parts that can be moved to tighten or unfasten any size of nut and bolt, not to be confused with a spanner, which has a fixed size.  Allegedly it was called Moncke's wrench after the inventor.   Of course the Americans say it was invented by a certain Charles Moncky of Baltimore who  patented it in 1830. Unfortunately for this explanation, the term is British in origin and predates Moncky by some decades, in addition there are 17th Century examples of this tool which were probably manufactured in London.   Either way, a monkey wrench has nothing to do with monkeys, which is a bit disappointing really.)
