Abstract: A rack is disclosed for storing food processor tool discs of the type having a receptacle or socket structure offset from its axis of rotation and located beneath the lower surface of the disc for receiving the upper end of a removable elongated hub on which the tool disc is mounted during operation, such receptacle having a generally crescent-like configuration. The rack includes a base having a plurality of parallel slots for receiving the tool discs and a vertical wall extending upwardly alongside each slot. Each of the vertical walls includes an offset portion for receiving the crescent-like hub receptacle of the tool disc.

Abstract: A horizontal disc-like tool head is detachably mounted on an upper coupling portion of an elongated hub, while a lower coupling portion of the hub is adapted to be coupled to and rotated by the tool drive shaft of a food processor. The tool head has a receptacle underneath it for receiving the upper coupling portion of the hub, which has a flange-like configuration with spaced, projecting, peripheral teeth. The receptacle has a plurality of spaced, lip retainers which are adapted to receive and retain such teeth when the hub is inserted in an axial direction and then rotated about the tool axis for changing its angular orientation in the receptacle. The teeth and lip retainers have corresponding matching sizes, so that the hub properly fits into the receptacle in only one position, thus preventing incorrect insertion of the hub.
