  • Patent number: 5143251
    Abstract: The application discloses a device (10) to retrofit into the cabinet (11) of newspaper vending machine racks to prevent the removal of more than one copy of the newspaper for each vend or door opening of the cabinet (11). The single vend device (10) consists of a front panel (12) with a T-slot (14). The arms (14a) of the T-slot (14) are normally closed off with a pivoted closure plate (16). Consumer access to the newspapers is provided through the leg of the T-slot (14b), but the newspaper must be slid through the gap between the closure plate (16) and the front panel (12). The thickness of the gap is adjustable to selectively allow for the variation in thickness between various editions of the newspaper. The closure plate (16) is spring loaded to be biased to the closed position. Following removal of the paper, the closure of the plate (16) and a locking pin (32) prevents the plate (16) from re-opening. The locking pin ( 32) is disarmed upon closure of the cabinet (11) door (25a).

  • Patent number: 5025908
    Abstract: A coin control mechanism (52) for use with a dispensing device having an access door. The coin control mechanism includes a door locking assembly disengaged by the action of a totalizer which rotates in response to the denomination of coins dropped through a coin chute. The totalizer is connected to a price control unit comprised of three rotatable slotted rings whose slot positions may be changed to reflect different desired cumulative values of coins needed to activate the mechanism by varying the position of the slots with respect to a release bar (510) and the other slots on the split ring assembly (500). The slotted rings advance towards the release bar (510) in response to the rotation of the totalizer. When a slot engages the relase bar (510), the release latch is activated and the access door is unlatched.
