Abstract
Abstract A hamburger bun storage device has a supporting frame on which a bun-toasting and heating element is disposed. The heating element is preferably a planar member superposed above a parallel planar conveyor mounted on the frame to advance in a predetermined direction. The heating element is movable up and down; i.e. toward and away from the associated conveyor. A drawer enclosure is disposed on the heating element on the side thereof opposite the conveyor and is open only in a direction transverse to the predetermined direction and at the side of the frame. A drawer is slidable in the drawer enclosure between an open position and a closed position in which a drawer end plate is in abutment with the frame.
