Abstract
A beverage brewing machine which has upper and lower brewing chambers which are movable relative to each other so as to clamp a strip-shaped filter therebetween during the brewing process and the chambers can be separated so as to allow the filter strip to be removed from the brewing chamber and the beverage residual wiped therefrom after which the filter strip is returned to the brewing chambers which are then resealed for the next cycle. A hold down grid engages the top surface of the filter to hold down as a piston moves in the lower chamber upwardly to force air through the filter to agitate the beverage. When the piston reaches top dead center, the hold down grid is lifted. When the piston passes the opening the brewed coffee is poured.
