Abstract
This invention relates to a variable speed vibratory conveyor or feeder which comprises a material-carrying member mounted on isolation springs, and an exciter connected to the member by a spring system. The exciter carries a rotatably mounted eccentric weight for imparting vibrations to the material-carrying member, and a hydraulic control system is provided for varying the position of the eccentric weight relative to its axis of rotation in order to vary the amplitude of the vibrations imparted to the material-carrying member.
