BlackFacts.com presents the black fact of the day for June 27.
Frederick Jones invents the ticket dispensing machine.
He was an U.S. inventor credited with more than 60 patents.
After a challenging childhood, Jones taught himself mechanical and electrical engineering, inventing a range of devices relating to refrigeration, sound, and automobiles.
