Is a method of converting [[reciprocating motion]] to [[rotary motion]] and was used in the first [[rotative beam engine]]s.

The [[crankshaft]] was well known for centuries before Watt, mostly from its use in mining machinery powered by [[water wheel]]s. However its use for a steam engine was covered by [[James Pickard]]'s patent at this time..<ref >{{Cite book

}}</ref> Watt was unwilling to pay a license fee to use the [[crank (mechanism)|crank]] and so sought an alternative. The sun and planet gear was invented by another [[Scottish people|Scottish]] engineer, [[William Murdoch]], an employee of [[Boulton and Watt]]. Watt patented it in October 1781.
