Abstract
Apparatus for brewing coffee, tea and other beverages which consists of a lower and upper chamber which move relative to one another. The upper chamber allows the mixing of the coffee and water. The lower chamber has a filter element at the top which allows the coffee liquid to move from the upper chamber to the lower chamber while leaving the residue on the filter element. A piston in the lower chamber forces air through the water and coffee to agitate it and then sucks the coffee liquid through the filter element into the lower chamber. The coffee liquid then exits the lower chamber through an opening in the lower chamber and goes into a cup. The upper chamber then raises and separates from the lower chamber and a wiper blade which is connected to the upper chamber cleans the filter element and pushes the coffee grounds into a residue container.
