Abstract
A vending machine has a frame comprising a newspaper holding compartment with a spring hinged door and a housing for a mechanical control system secured to the top of the holding compartment. A vending member is secured to the door and operably engaged with the control mechanism. The control mechanism includes a lever biased to a locking position with respect to the vending member. A lever holding rod is secured to the lever and has an 'up', or unlocked, position wherein the lever does not lock the vending member, and a 'down', or locked, position wherein the vending member is locked in position. A coin operated mechanism has an output shaft and cam which rotate in response to the insertion of a low price coinage amount to a first position, and a high price coinage amount to a second position. A second cam is mounted for free rotation on the coin mechanism shaft and is gravity biased to follow the first cam. The second cam follows the first cam to rotate freely to the first position wherein it holds the lever holding rod in the 'up', or unlocked, position so that the vending member is unlocked. A lock out member which is operated by an exterior key is provided to block the free rotation of the second cam so that only the first cam rotates to the second position when the high price amount of coinage is inserted. In the second position, the first cam holds the lever holding rod in the 'up' position so that the vending member is unlocked. A reset mechanism for the coin operated mechanism is provided.
