ABSTRACT:
A vibratory device operable as a two mass vibrating system comprising a base mass and a work member mass spring coupled and mounted on isolator springs and operating at a frequency approximating the natural frequency of the system. A multiple number of leaf springs inclined at an angle to the base and work member mounting plate provide a combination of torsional and vertical amplitude required to cause the conveying action of the work member. The exciter for the vibratory device is an AC powered multiple electromagnetic oscillator having a fixed redial air gap eliminating the possibility of self destruction by impact of the poles faces without limiting the amplitude of the vibratory device.
