Image Number 4 for United States Patent #4666060.
An apparatus for dispensing frusto-conical pots, such as nursery or plant pots, including a pair of pivotally connected arm members arranged for movement toward and away from each other on opposite sides of a stack of pots to be dispensed. Each arm member, or each set of arm members, supports a plurality of feed cylinders, each having a spiral groove in its cylindrical surface, adapted to engage opposite sides of the stack of pots and adapted to be rotated in a direction to cause the lowermost pot or pots to separate and drop from the upper pots in the stack. An adjustment mechanism is included for moving the arm members toward and away from each other in order to accommodate stacked pots of different diameters. An overhead conveyor may be provided for feeding stacks of pots to the dispensing position between the arm members.
