A coffee brewing machine which allows the coffee to be more rapidly removed from the lower brewing chamber by providing a vent opening which opens to relieve the vacuum and allows the coffee to be discharged. In one embodiment, the vent opening is opened and closed by a plug on the upper brewing chamber. On another embodiment the vent hole is opened and closed by an actuator. In a third embodiment, a portion of the coffee filter serves as the vent hole.

Lower chamber vent for the lower chamber of a brewing machine

An improved tea brewer which can be attached to a coffee brewer and has a tea wiper that connects to the coffee wiper for removing tea leaves from the machine.

Tea brewer

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.

Coffee brewer method and apparatus

An apparatus for brewing coffee, tea or other beverages that has upper and lower chambers that move relative to each other. When the upper and lower chambers are joined, coffee and water are supplied to the upper brewing chamber which passes through a filter mounted on the top of the lower brewing chamber into the lower brewing chamber and the coffee grounds remain on the filter. A piston in the lower chamber forces air through the liquid to agitate it and sucks it through the filter into the lower chamber. The coffee flows from the lower chamber and then a single push rod separates the upper and lower chambers. A wiper blade then removes the coffee grounds from the filter while the chambers are separated after which the push rod reseals the upper and lower chambers together for the next brewing cycle.
