  • Patent number: 4920871
    Abstract: A beverage (tea and coffee) making appliance of the type having a reservoir wherein a supply of hot water for brewing is maintained and from which a volume of the hot water is displaced by an equal volume of a batch of cold water discharged by gravity from a cold water basin through a fill tube into the bottom of the reservoir. The displaced hot water is discharged into a brewing funnel lined with a filter on which the beverage forming material (ground coffee or tea leaves) is placed. The cold water basin is equipped with a removable standpipe-like fitting on the upper end of the fill tube through which cold water enters as long as the level of water in the cold water basin is above the upper end or entrance opening in the fill tube. The fill basin has a second drain opening to which is connected one end of a tube the other end of which discharges into a portion of the brewing funnel which is partitioned off from the filter lined portion.
