Thomas W. Stewart was the inventor of the mop, the metal bender, and the railroad crossing indicator. Thomas W. Stewart got the official patent for his invention on June 11. Thomas was an African American that loved to invent new things to help the community. He invented the mop to help someone in need of it. If Thomas W. Stewart wouldn't have invented the mop then we would have to get down on our hands and knees to mop up the floor.

Thomas W. Stewart also invented the metal bender. Think about what that can do... it can help make the water heaters we have today.

He also invented the railroad crossing indicator. If he never invented that then we would have at least six trains killing over ten people every month or two. That is a lot of people to kill by a train wreck if you think about it...
