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. In making iced tea, the portion of hot water flowing into the brewing funnel forms a concentrate which on discharging from the brewing funnel combines with the cold water entering the partitioned-off portion of the brewing funnel thereby forming iced tea stock. When the standpipe is removed and the second drain opening is closed the applicance can be used to brew coffee or tea in conventional manner.

In beverage brewing apparatus comprising, in combination, a cold water basin having a first drain opening and a fill opening through which a batch of cold water may be poured or dumped, a hot water tank under said basin, means for heating water in said tank, a cold water tube having its upper inlet end connected to said first drain opening and having its lower outlet end disposed in the lower portion of said hot water tank whereby cold water in said basin drains by gravity into the lower portion of said hot water tank, a hot water spray head, a siphon tube interconnecting said spray head with a hot water outlet in or adjacent the top of said hot water tank whereby hot water displaced by cold water entering the lower portion of said hot water tank flows through said siphon tube to said spray head through which it discharges, and means for supporting a brewing funnel beneath said spray head, the improvement comprising: a brewing funnel on said brewing funnel support means comprising a hot water receiving compartment disposed beneath said spray head, a cold water receiving compartment exterior to said hot water receiving compartment, and a funnel bottom outlet opening in communication with both said compartments; a tubular cold water inlet fitting mounted in said basin, and having an inlet opening located above said first drain opening and an outlet opening communicating with said upper inlet end of said cold water tube whereby said tubular cold water inlet fitting forms an upper extension of said cold water tube; and, said basin having a second drain opening and a cold water drain tube interconnecting said second drain opening with said cold water receiving compartment of said brewing funnel, whereby when said basin contains cold water at a level above said inlet opening in said cold water inlet tube, cold water drains simultaneously into said hot water tank and said cold water receiving compartment until said level drops below said inlet opening in said cold water inlet tube after which the remaining water in said basins drains through said second drain opening.
