Patent number: 5285705Abstract: A beverage mixing apparatus such as a coffee grinding and brewing apparatus is provided with an operative cycle which includes the transportation of a predetermined amount of a solid component of a beverage mixture from a storage compartment to and through a passageway into a mixing chamber wherein the liquid component of the beverage is mixed with the solid component. The apparatus further comprises a valve assembly associated with the passageway and having a plate movable between a closed position and an open position. The plate defines an opening which registers with the passageway when the plate is in the open position. A solenoid is connected to the plate for moving the plate between its open and closed positions. When the plate is in its open position the solid component can be moved from the storage chamber to the mixing chamber. In the closed position, the plate prevents moisture from the mixture from moving to the storage chamber through the passageway.Type: GrantFiled: April 6, 1993Date of Patent: February 15, 1994Assignee: Grindmaster CorporationInventors: Donald R.

Patent number: 4913037Abstract: A system for preventing the escape of moisture from a beverage preparing device, such as a coffee brew basket, into apparatus for delivering a dry particulate food product, such as a coffee grinder, to the device during the beverage preparing process. The system includes a support plate containing a rectangular opening. A brew basket can be removably suspended from the plate under the opening. An elongated rod, rotatable about its longitudinal axis, is connected across the plate so as to extend across an edge of the opening. A flap is fixedly attached to the rod for tilting as the rod rotates between a closed position in which the opening is sealed against moisture penetration and a downwardly extending position such that the food product can be delivered through the opening to the basket. A spring biases the rod to an angular position of rotation such that the flap is normally closed to seal the opening.Type: GrantFiled: June 6, 1989Date of Patent: April 3, 1990Assignee: Grindmaster CorporationInventor: Brian D.

Patent number: 4878625Abstract: A grinder refinement mechanism for use with a conventional coffee or peanut grinder is disclosed. The grinder includes the usual screw conveyor having a rotary grinding burr attached to a forward end thereof, a stationary grinding burr connected to a wall of the grinder housing and a main spring which biases the screw conveyor toward the forward end of the grinder housing against an adjustment screw projecting through an end wall. The mechanism includes a lever arm pivotally attached to an outside surface of the end wall and an electrical solenoid connected to the arm. The usual adjustment screw is replaced with a plunger element which slidably projects both into and out of the end wall and is confined between a forward end of the screw conveyor and the arm. In one condition of the solenoid, the main spring forces the screw conveyor and plunger forwardly to hold the arm against a stop screw which thus determines the desired coarse grinding condition of the grinder burrs.Type: GrantFiled: July 29, 1988Date of Patent: November 7, 1989Assignee: Grindmaster CorporationInventor: Brian D.
