  • Patent number: 4508238
    Abstract: A single copy newspaper vending machine which dispenses one newspaper copy each time proper coins are deposited. Newspapers are stacked on a tray which is urged upwardly toward a ski device that rides on the newspaper stack. The ski device can be pulled forwardly to dispense a single newspaper by depositing proper coins and pulling on the handle of a slide arm. The slide arm is normally locked in a retracted position but is released when the coins are accepted. The ski device includes pointed prongs which penetrate the upper surface of the top newspaper in the stack. The back folded edge of the top newspaper is engaged by cleats projecting from a cleat plate carried on the ski device. A pivotal dog member assures that the slide arm is moved through a single complete stroke each time it is released. After the stack of newspapers on the tray has been exhausted, the next stroke of the slide arm causes the dispensing of a display copy carried in a display case on the front of the machine.
