  • Patent number: 6378724
    Abstract: A machine and method for vending products perform the operational steps of storing a multiplicity of products in a plurality of vertical columns thereof that are organized in a circular row wherein the products in each vertical column are disposed one above another and can feed downward due to the influence of the force of gravity, incrementally rotating the plurality of vertical columns of products simultaneously about a circular path wherein lowermost ones of the products in the vertical columns thereof one at a time per revolution advance and cross over an inlet opening to a dispensing path, and dispensing the lowermost ones of the products of the vertical columns thereof through the inlet opening by use of a separation fixture that prevents products from dropping directly into the inlet opening from the vertical columns when aligned above the inlet opening while letting products drop into a lowermost circular row thereof located below the columns and from the lowermost circular row one at a time through t

  • Publication number: 20020036209
    Abstract: A machine for vending products include a housing, an magazine indexing drive mechanism in the housing and drivingly coupled to a product storage and dispensing magazine at spaced apart lower and upper portions of the magazine, a plurality of ball bearings rotatably supporting the magazine on a product separation fixture in the housing, a resiliently yieldable mechanism supported on the separation fixture and having a spring-biased pivotally-movable flap operable to impart a positive downwardly-directed force on the lowermost product that will push it downward toward an opening in the housing, and portions of the housing and the separation fixture defining a path for passage of products to the opening which is located outwardly of and bypasses the drive mechanism.

  • Patent number: 6270080
    Abstract: A coin-operated item vending and game apparatus includes a coin-operated item vending machine and a game module. The vending machine includes a support base, coin deposit, vendable items dispenser, globe and elongated central support member. The game module includes a housing, target and flexible resilient lever. The housing is disposed within the globe. The target is disposed within the housing. The lever is disposed below the target and extends through the housing and globe such that an outer end of the lever is disposed exteriorly of the globe. A depression defined on the lever receives a coin. The outer end of the lever is manually depressed downwardly by the user causing bending of the lever from an initial condition and creating an upward force because of the resiliency of the lever. Release of the lever by the user allows the lever to spring back to its initial condition and toss the coin upwardly such that the coin will either make or miss the target depending on the skill of the user.
