SELF LEVELING DISPENSER Abstract of the Disclosure A self-leveling dispenser provides a rack supporting a stack of trays within a frame. A revers- ible motor drivably connected to spiral shafts mounted at the corners of the frame rotates the shafts to provide upward or downward movement of the rack, which is supported on the spiral shafts by threaded sleeves. An upper sensor mounted to the frame is operably connected to the motor to move the rack downward upon detecting a tray at an upper horizontal level above a desired height. A lower sensor mounted to the frame is operably connected to the motor to raise the rack upon sensing the absence of a tray at a lower horizon- tal level below the desired height. The sensors cooperate to automatically and continuously reposition an uppermost portion of a top tray in the stack at the desired height with respect to the frame, thereby to facilitate dispensing of dishes or food products.
