Abstract
A coffee grinder useful in business offices or small restaurants. A hopper for coffee beans has an outlet in its lower wall. A motor is mounted vertically within the hopper. A stationary grinding burr and a rotatable grinding burr, which is driven by the motor via a vertical shaft extending through the outlet, cooperate to grind such beans into smaller grounds and to expel such grounds radially and horizontally between the burrs. A wall having an aperture surrounds the burrs and prevents such grounds from being expelled except through the aperture. A deflector mounted to the wall, outside the aperture, deflects such grounds downwardly in a concentrated stream.
