Abstract: A coffee grinder-dispenser comprising a base housing an electric motor, with a vertically extending rotatable shaft which is connected to a grinder located in a grinding chamber. A vessel located above the grinding chamber receives coffee beans to be ground. A closure plate allows the coffee beans to enter the grinding chamber. A conduit allows the coffee, after grinding, to be delivered to a funnel; the ground coffee passes downwardly through the funnel into a filter holder. One cooling fan faces the grinding chamber, is activated by a keypad on the funnel, and delivers air transversely across the interior of the housing. A second cooling fan is located on the vertical shaft of the electric motor. The fans are operated by a controller, located within the housing, and provide sufficient cooling air to the grinding chamber to maintain the desired qualities of taste and aroma in the ground coffee.

Abstract: A coffee grinder-dispenser comprising a base, a grinder located within the base, an electric motor for operating the grinder, and a hopper, or cup, for receiving the coffee beans to be ground. A funnel is secured to the base, to receive the ground coffee, or powder via a distribution channel that extends in a horizontal plane. A grid, comprising spaced stainless steel rods, extending vertically and horizontally, is positioned in the entry hole or port of the funnel in alignment with the distribution conduit of the grinder-dispenser. The grid reduces the velocity of the ground coffee, or powder, so that the powder does not accumulate upon, or adhere to, the walls of the funnel. Consequently, when a lever on the base is operated, an accurate amount of ground coffee is discharged from the funnel into a conventional filter holder.
