Abstract
A vibratory conveyor employing an amplitude compensator to substantially impede the conveyor bed from moving beyond a given range of vibration amplitude is described. The amplitude compensator coacts with the conveyor bed as the vibrational amplitude of the bed increases in response to an increase in the mass of conveyed product, or to an increase in the vibrational force produced by the vibratory drive to impede or substantially eliminate premature wear or mechanical failure of leaf springs which support the bed.
