Abstract
An appliance for slicing and shredding vegetables, fruits, cheeses and other food products having an improved safety interlock wherein the cover for the receptacle in which the slicing and shredding is performed includes means for completing the mechanical coupling between the motor and the slicing and shredding implement. The receptacle within which the slicing and shredding is performed is provided with a novel slicing and shredding implement which cooperates with the shape of the receptacle to minimize clogging and facilitate the discharge of the sliced and shredded food from the receptacle.
