Zusammenfassung:	DRIVES The present invention describes a spring coefficient adjustment system for a vibratory drive for use in driving a vibratory delivery apparatus. The drive includes an electromagnet and an associated armature spaced apart by a gap. In the drive, a plate is movable with respect to a frame. One of the electromagnet and the armature is connected to the frame and the respective other is connected to the spring plate. A primary spring is connected between the frame and the spring plate. A plurality of auxiliary elastomer shear springs is selectively engageable between the frame and the plate to change the total spring coefficient between the frame and the plate. Un sistema de ajuste de coeficiente de resorte para un dispositivo vibratorio para usarse en conducir un aparato vibratorio de entrega. La transmision incluye un electromagneto y una armadura asociada separada por una abertura. En la transmision, una placa es movible con respecto a un marco. Uno del electromagneto y la armadura esta conectado al marco y el otro respectivo esta conectado a la placa de resorte. Un resorte primario esta conectado entre el marco y la placa de resorte. Una pluralidad de resortes de corte de elastomero auxiliares son selectivamente acoplables entre el marco y la placa para cambiar el coeficiente de resorte total entre el marco y la placa.
