Sun and planet gear
The sun and planet gear was a method of converting reciprocal motion to rotary motion and was utilized in a reciprocating steam engine. It was invented by the Scottish engineer William Murdoch, an employee of Boulton and Watt, but was patented by James Watt in October 1781. It was invented to bypass the patent on the crank, held by James Pickard. It played an important part in the development of devices for rotation in the Industrial Revolution.
