Abstract: A vending apparatus is disclosed which is adjustable for delivering products of different sizes and shapes and which is particularly suited for easy field conversion or changeover for a desired product delivery. The vending apparatus includes a plurality of identical rotary dispensing shafts each having a helical scroll with the dispensing shafts vertically disposed in an aligned array. To establish a preselected drop-off for a given product, the dispensing shafts are each angularly adjustable relative to one another. A power operated, rotary actuator shaft is provided with a plurality of gears fixed on the actuator shaft. The actuator shaft gears are meshingly engageable respectively with a corresponding gear on each dispensing shaft.
