<p>A pallet dispenser (10) includes a frame adapted to support a stack (14) of pallets (12). The frame includes four screws (40,42,44,46) with spiral flights (58). The pallets rest on the top edge of the spiral flights (58) of the screws. Rotation of the screws then lowers the stack and allows the bottom pallet to drop to a support below the screws.</p> |
