  • Patent number: 4511059
    Abstract: A vending or dispensing machine is operable in triple depth, double depth, and single depth operating modes. A cradle which is rotatable through 360.degree. is used to separate cylindrical articles from a number of tandem nonstaggered vertical columns. The rotatable cradle separates a single can or other cylindrical article from each of the columns disposed in a storage zone above the cylindrical cradle and drops the cans into an escrow zone. One of the cans in the escrow zone is immediately dispensed. If operating in a triple depth mode, the remaining two cans are held by side mounted pivotable escrow members which are controlled and movably operable by the cradle itself. Upon a second activation the cradle moves further in its sequence allowing one of the escrow members to release its hold on a second can such that that can drops into a dispensing zone accessable to a consumer.
