Abstract
A coffee brewing and serving machine is provided with an upper housing portion from which hot water is dispensed in a downwardly flowing stream through a removably mounted, large funnel containing a large foraminous basket in which is disposed filter paper and coffee grounds. Below the outlet of the funnel is a lower housing portion containing a coffee tank having a vertical wall dividing the tank into two substantially equal sized coffee holding urns. An urn cover is supported on an upper portion of the lower housing portion over the coffee tank. The urn cover has an orifice in vertical alignment with, and below, the funnel outlet. Further there is a channel-shaped diverter trough on the underside of the cover below, and in alignment with, the cover orifice. The cover is adapted to be rotated on the top of the lower housing about a vertical axis passing through the cover orifice and funnel outlet whereby the stream of brewed coffee from the upper housing passing through the funnel and cover orifice can be directed by the diverter trough to either one of the two coffee holding urns. A small funnel and basket assembly are provided and adapted to fit within the large funnel and basket assembly for use in making a smaller batch of coffee. Annunciator systems are provided to alert the operator to remove used grounds after a batch of coffee has been brewed and to dispose of brewed coffee that has been held in an urn beyond a predetermined period of time.
