Self-acting mule
The article says
 * On October 8, 1840, Mason's greatest invention, the "self-acting mule" was patented. Competition required improvements and on October 3, 1846, he received a patent for "Mason's Self-acting Mule."

However, at Spinning mule, we find that Richard Roberts had priority, his patent being granted in 1825. -- Red rose64 &#x1f339; (talk) 20:10, 21 June 2018 (UTC)
