Abstract: A mechanism kit is provided to enable fast and economical conversion of existing semi-honor newspaper vending machines to machines for dispensing one newspaper or magazine at a time following the insertion of proper coins into the conventional coin control mechanism. The customer thus has access to only a single newspaper and not the full contents of the vending machine after insertion of the coins. A manually operated reciprocating single newspaper gripping, transporting and release device withdraws each paper through a narrow slot in the front, side or top of the dispensing machine cabinet and this device is connected with a reciprocating element of the coin mechanism which is released for movement only after the insertion of proper coins by a customer. An associated cabinet door lock and release linkage releases the door for access by the customer to the last newspaper held on the cabinet door after the customary stack of newspapers is exhausted.
