Ratchet Gearloose is a fictional character from the Walt Disney comic strips. He is inventor Gyro Gearloose's grandfather.
Ratchet knew Scrooge McDuck: he first met him during his Mississippi riverboat days. They later met on the island of Krakatoa. Nothing was known about Ratchet since then but it is assumed that he wound up in Duckburg since his son Fulton Gearloose is one of the first three Junior Woodchucks.
