  • Patent number: 5269439
    Abstract: Unauthorized removal of packages from coin-operated vending apparatus is prevented by a gravity operated lock which prevents removal of the ejector from the column of packages in the dispenser. The lock can only be removed from the locking position by movement of the connecting link by which the coin-operated slide moves the ejector to remove packages from the column of packages.

  • Patent number: 4960226
    Abstract: Disclosed is apparatus for dispensing cylindrical objects such as pencils. The objects are stored in a hopper within a housing and fall out of the hopper into a delivery reservoir which is movable between a first position and a second position. When an activation mechanism moves the reservoir to the second position, the objects in the reservoir fall to an outlet in the housing. As the reservoir moves to its second position, an agitator aligns the pencils in the hopper to avoid bridging. A platform over the hopper holds some of the objects off the objects in the hopper. A patina on the agitator holds the high friction parts of the objects off the agitator so the objects roll or slide more easily.
