  • Patent number: 5778767
    Abstract: A dispenser for dispensing a predetermined quantity of food articles, such as frozen french fries, frozen chicken pieces, cheese sticks, and the like, having a support structure supporting a hopper, the hopper having a storage area positioned over an exit opening and a dispenser drum between the storage area and the exit opening. The dispenser drum is rotatably mounted in the hopper between two end walls on the hopper. The dispenser drum has an axis of rotation, a sealing lip at a first radius perpendicular to the axis of rotation and a catching lip at a second radius perpendicular to the axis of rotation. The second radius is longer than the first radius creating a non-cylindrical shaped dispenser drum. A diverter is pivotally mounted in the hopper. The diverter is positioned to be bumped by the dispenser drum to jostle food articles in the storage area. A driver portion is mounted on the support structure to engage and rotate the dispenser drum about the axis of rotation.
