  • Patent number: 4516484
    Abstract: An appliance for preparing hot beverages, such as a coffee maker, comprises a boiling chamber heated by an external or internal source, a vessel adjoining the boiling chamber in which water is indirectly heated to form an infusion, and a cup removably seated on that vessel for holding a liquid--e.g. milk--to be separately heated. A tube with a restricted outlet, which may be designed as a gooseneck, rises from the boiling chamber to discharge steam into the liquid contained in the cup. The boiling chamber may form a platform for the infusion-brewing vessel or may spacedly surround same, the steam tube passing axially through the vessel in the latter instance.
