ABSTRACT:
An automatic brewing apparatus having a reservoir of water heated by a thermostatically controlled heater which is pumped via flexible conduit to a movable head which temporarily seals and communicates with a special packet of coffee or other brewable substance and produces a beverage by rapid infusion. Packets are mounted upon a tape which threads through a brewing basket where infusion takes place while the tape is initially wound upon a supply reel which feeds a take-up reel after passage through the brewing basket. The cooperation of these features is brought about by a control circuit which is activated by a momentary switch and consequently causes, through a drive means, the passage of the tape through the brewing basket until a packet is centered. The control circuit then stops tape passage, activates the movable head to communicate with the packet and activates a pump to force water through the grounds, brews the beverage and then shuts the apparatus off.
