Abstract
A swivel drawer assembly is provided which finds general utility in automobile pass-through food dispensing establishments, and which comprises a horizontal tray mounted for swivel movement in a rectangular opening in the wall of the establishment about a first vertical axis at one side of the opening. First and second vertical doors are mounted at right angles to one another on one side of the tray with their junction at the first vertical axis, and third and fourth doors are independently swivelly mounted for rotation about a second vertical axis at the other side of the opening. The third and fourth doors are coupled to the tray through a cam action to be turned about the second vertical axis by the tray, and the assembly is such that when the tray is turned to one limiting position the first and third doors close the opening, and when the tray is turned to its second limiting position the second and fourth doors close the opening.
