ABSTRACT:
An improved tobacco dumper is provided with a brake means for safely holding the dumper in a raised position blocking the hood opening of a tobacco feeder. Control apparatus prevents brake engagement until the dumper is in an upper dump position, and prevents dumper return until a specific control input is received and the brake is positively disengaged. Apertured drive sprockets and aligned brake pins are utilized.
