Abstract

See full text

A large capacity elevator-type napkin dispenser comprising an elongated supporting structure or cage composed of a series of spaced rod-like vertical supports. A stack of folded napkins is supported on a pressure plate that is mounted on a carriage adapted to slide vertically within the cage. The pressure plate is supported from the carriage by a plurality of compression springs which enable the pressure plate to float and accommodate the varying thickness of the stack of folded napkins. A cover is mounted on the upper end of the cage and has an opening through which the napkins are dispensed. The pressure plate and stack of napkins are urged upwardly toward the undersurface of the cover by a biasing mechanism that includes a pair of extension springs. The springs have a varying spring rate so that the force of the springs will be greatest when the pressure plate is fully loaded with napkins.
