Abstract
Abstract A funnel is disclosed for use in brewing beverages such as coffee, tea and the like and for discharging the beverage into either of a plurality of spaced reservoirs below the funnel. The funnel includes an upstanding side wall, a bottom wall, and flow channel means associated with the bottom wall which communicates between the interior of the funnel and a discharge port spaced from the center of the funnel for selective discharge of liquid into alternate reservoirs by turning the funnel. Stop means provided at a selected radial position on the funnel cooperate with limiting switches or the like on the brewing machine to prevent brewing unless the funnel is in the proper location for discharge into a reservoir.
