ok so i have this history thing where we have to find dates for when different things were invented....and we have to find out when the mechanism for lining machinery was invented..i know that Elijah McCoy invented it but i have no idea when it was invented!!! please please please help!!!!!!!!!!! :)
the mechanism for lining machinery was invented in the late 1800s. i think around 1877? i'm not sure. it was definitely the late 1800s, though.
