A coffee grinder in which coffee beans can be selectively fed by gravity to the grinder mechanism from either of two hoppers. Separate reciprocable slides close off or open separate discharge openings communicating between the bottom of each hopper and the grinder inlet for beans. The slides are operated by separate solenoids. An electrical control circuit including a dual timer, two solenoids and the grinder motor, allow an operator to selectively grind a predetermined quantity of beans from either of the hoppers.

In a timer-controlled coffee grinder comprising a motor-grinding unit having a bean inlet opening in the top of the grinder and a ground coffee discharge opening in the bottom thereof, a coffee bean funnel having its bottom outlet opening disposed to discharge beans by gravity into said bean inlet opening, a coffee bean hopper having a bottom outlet opening disposed to discharge beans by gravity into the top of said funnel, means dividing the interior of said hopper into two side-by-side chambers and said hopper bottom outlet opening into separate side-by-side discharge areas with each area communicating with only the one of said chambers located above it, a separate slide for opening and closing each said discharge area, means for mounting each said slide for reciprocable movement between a first position closing its associated discharge area and a second position opening of said discharge area, separate reciprocating means including a solenoid for each said slide, means operatively interconnecting the armature of each said solenoid with one of said slides for shifting the same into at least one of its said opening or closing positions, and electrical control circuit means including a separate circuit for each said solenoid and including a timer whereby each slide may be selectively shifted from its closed position to its said area opening position in which it remains for a preselected time period after which it is automatically shifted back to its closed position.
