  • Vending machine including refrigeration and oven compartments
    Patent number: 5772072
    Abstract: A vending machine includes a refrigeration compartment, an oven compartment, structure for transferring a food product from the refrigeration compartment to the oven compartment, and structure for transferring the food product from the oven compartment to a user of the vending machine. The vending machine provides automated handling and cooking of packaged food products that enables a hot cooked food to be delivered to a customer in a cool package sleeve. The vending machine also includes a system for inventory control that enables vertical storage of packaged food products while minimizing crushing of packaged food products at the bottom of a stack. A magazine empty indicator automatically indicates when an inventory magazine is empty. An oven door latch mechanism eliminates the possibility that the oven can be operated while the oven door is open.

  • Method of controlling inventory carousel in vending machine
    Patent number: 5590809
    Abstract: A food vending machine contains a motor-driven inventory carousel which rotates to position food items at a desired index position. A control unit, for example a computer, reduces the power delivered to the inventory carousel as the desired index position is approached. The mechanical drive for the inventory carousel includes a modified geneva mechanism, which also serves to reduce the acceleration forces on the inventory carousel as it rotates from position to position.
