ABSTRACT:
Disclosed is a dispenser of the type having a suspended, upwardly biased, carrier plate for holding trays, plates, etc. and for automatically advancing the load of articles to present the uppermost article at a predetermined position near the open top of the dispenser. The dispenser has an improved biasing system for achieving the automatic advancement of the load employing compression or tension springs as the biasing means and a deformer supported for vertical movement with the carrier plate and for horizontal movement relative to the carrier plate so that it can bear upon the biasing means to cause deformation thereof. A cam member is obliquely supported on the frame within which the carrier moves and horizontally deflects the deformer as the carrier tray is depressed. Thus, the further the carrier plate is depressed (e.g., by the addition of items to the stack which the carrier plate supports) the greater will be the deformation of the biasing means and the greater the biasing force acting against the deformer and cam member to urge the carrier plate upwardly. The cam member can be adjusted in its angle with respect to the vertical to vary the amount of deformation of the biasing means at any given vertical position of the carrier plate, thereby permitting the adjustment of the biasing force so that the dispenser can be used to dispense articles of different weights with the appropriate balance of the weight of the stack of articles and the upward biasing force.
