Abstract: A rollably portable insulating cabinet having top openings for the replacle installation of self-leveling dispensers for stacked plates and the like has removeably assembled thereto, through a bottom opening, an air heater and blower assemblage of unitary structure and having longitudinally-extending heating elements so arranged and located with respect to vertically extending slot openings in the plate dispensers as to efficiently circulate blower-forced air heated by the heating elements through the plate dispenser slots for uniformly heating stacked plates within the dispensers.

Abstract: An adjustable, self-leveling dispenser for stacked plates has a load carr within a plate well or tank and a plurality of tension springs peripherally arranged about the outer periphery of the tank and connected between a lower spring carrier ring moveable along the outside of the tank and an upper spring carrier ring fixed with respect to the tank, the lower spring carrier member being secured to radially-extending support members projecting through longitudinally-extending slots in the tank for yielding and supporting the load carrier from underneath. A plurality of guide rod members vertically disposed in spaced relation within the tank and stepwisely adjustable along a range of distances outwardly of the center of the pressure head serve as abutment slide means for guiding peripheral edge portions of any selected size of a wide range of sizes of stacked plates to be dispensed.
