Which mechanism did Watt famously use to convert reciprocating motion into rotary motion?

Answer

Sun and planet gear system

To make the engine useful for general machinery beyond pumping, Watt developed mechanisms to convert the engine's inherent up-and-down (reciprocating) motion into circular (rotary) motion, utilizing the sun and planet gear system most famously.
