  • Patent number: 4842416
    Abstract: The present invention relates to an agitating and kneading tool (4) for being inserted into the center of a mixing bowl (2) of an electrically driven household appliance (16). The agitating and kneading tool (4) is conventionally composed of a hub (15) to which two differently shaped types of single tools (3, 10 and 1, 8) are fitted and which are drivable by a drive shaft (9) which preferably extends through the container bottom. It is suggested to furnish the hub (15) with a larger diameter in its lower area than in its upper area, in particular, to give it a conical shape. In its lower area, the hub (15) disposes of one or more single tools (1, 8) in the form of laterally projecting agitating arms, the said tools extending closely adjacent to the bottom in parallel to said. In the upper area of the hub (15), there is provision of one or more single tools in the form of kneading blades (3, 10).

  • Patent number: 4799626
    Abstract: The invention is directed to a food processing apparatus (2) having a lid (22) adapted to be placed on a vessel (10), with a cover member (26) of semi-circular cross section and having a passage (24) opening into the vessel (10) being provided on the lid. The cover member (26) is provided with a vertically extending rectangular receiving opening (32) for receiving a semi-cylindrical receptacle (34) adapted to swivel through 180.degree. between a loading position and a discharge position. The receptacle (34) is adapted to receive whole fruits (45) without the operator contacting the shredding or cutting tools (12, 13), because the receiving opening (32) is closed in the loading position of the receptacle (34). Following loading of the fruits (45) into the receptacle (34), the latter is swivelled through 180.degree.
