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. A spring-loaded receptacle rod protrudes from the upper coupling member, and this retractable rod and its associated locking recess are offset from the axis of tool rotation for preventing removal of the hub from the receptacle, unless the rod is manually retracted by its release button. During manufacture, the receptacles in various tool heads may be provided with different size shims mounted between the receptacle and the lower surface of the tool head for producing slicing tool heads having different slicing thicknesses without changing hub length. Accordingly, one elongated hub can be used with several different tool heads.
