Abstract

A coffee mill with two bins for holding two types of coffee. The bins slope downwardly and inwardly to provide two adjacent bin outlets. These outlets feed into the entrance to a coffee grinder. A slider plate and a baffle plate are slidingly mounted between the outlets and the entrance, and can be used to close the outlets altogether or to partially or entirely close all of one outlet, leaving the other outlet open. The slider plate removably interfits with the baffle plate so that moving the baffle plate causes both plates to slide together, in order to determine the coffee mix. When the two plates are in the position in which the slider plate covers both bin outlets, the slider plate fits within and is carried by a supporting frame proximate to the outlets. As a result, the bin and the slider plate can be lifted, and the slider plate will seal the bin outlets and prevent spillage of the coffee beans remaining in the bins. The baffle plate separates from the slider plate at this time and remains in position over the grinder entrance, closing it.
