Abstract
Abstract An apparatus for feeding items in a given direction through the use of controlled vibratory motion. An open ended chute is mounted above a base in spaced relation. An armature fixed to the chute extends into the base and is vibrated by an electromagnet mounted within the base. The chute is mounted above the base by a first and second stack of leaf springs. The first stack of leaf springs is arranged vertically so as to be perpendicular to the chute. The second stack is arranged obliquely with respect to the first stack of leaf springs. A cover plate is mounted to the base enclosing the electromagnet and a rubber grommet mounted to the base is in sealing relationship with the armature. Rubber feet are mounted beneath and to the base.
