<p>Single drive conveyor apparatus (10) including an elongated material-conveying conveyor having vibration-generating means (V) connected to one end thereof and vibrating the same substantially only in a direction parallel with the longitudinal centroidal axis thereof and including two pairs of parallel vibration-generating shafts (21, 22 and 28, 32), each pair having axial displacement relative to the other and each shaft of each pair carrying eccentrically mounted weights (35, 37 and 29, 33) generating equal forces and rotating in opposite directions, and controllably shiftable phase-adjustment/motion-altering mechanism (50) engaging drive element continuums and shortening one of said continuums (77, 78) while lengthening the other as said mechanism (50) shifts to thereby controllably alter the axial displacement existing between the shafts of said two pairs.</p> |
