This invention is a manually operated beverage brewer that is powered by a user articulating or turning a lever a multiple of times. The lever forces a small piston into a cylinder, which in turn pressurizing a hot liquid poured into the machine. The pressurized liquid flows through a pack of coffee grounds and out of the machine after the user has generated a minimum pressure to overcome an under-pressure valve. The user continues to articulate or turn the lever until the desired amount of coffee exits the machine.


1. A user powered beverage brewing device comprising: a liquid reservoir;a food chamber;two pistons;two cylinders;a lever; anda filter;wherein said two pistons matingly and slidingly fit within said two cylinders;wherein said lever is articulated manually by a user such that said two pistons move in an alternating and reciprocating manner, such that a liquid that is added to said liquid reservoir is drawn into said two cylinders, and wherein said liquid is alternately pressurized by said two pistons within said two cylinders in a substantially continuous...
