Abstract
A spring-driven pusher device for a forward, side, top, or up feeding merchandise dispenser having an adjustment mechanism for setting a desired pushing force. The adjustment mechanism is utilized to increase and/or reduce the tension of the windings of the coiled end of a spring or strip of coiled metal carried on the pusher device. The tension in the windings is increased if greater pushing force is desired, or decreased, if less pushing force is desired. Since the desired pushing force can be set, the same spring-driven pusher device can be utilized to feed various different products, regardless of size, shape, weight or surface texture.
