    Patent number: 8464861
    Abstract: A balanced vibrating conveyor apparatus is provided by using a torsion bar spring and rocker arm for conveyor trough and balancing weight. The design provides synchronized 180° out of phase vibrations of trough and balancing weight as well as balance at variations in stroke lengths. With a torsion bar spring at the rocker arm node point, dynamic forces are minimized in the conveyor frame, as well as the building support structure.
