  • Patent number: 5462155
    Abstract: A linear vibratory conveyor has a bottom plate and a vibratory conveyor track. Together with a trimming weight, the latter forms a vibrating mass. Further, a countermass is provided forming a mass vibrating in an opposite direction. The support of the masses, vibrating reciprocally, referred to the bottom plate takes place by way of spring elements formed by leaf springs. An electromagnetic vibratory drive fed by a cycled d-c potential engages between the masses vibrating reciprocally. A coupler of elastically damped action is provided between the masses vibrating reciprocally for the masses to vibrate exactly reciprocally one referred to the other even when out of resonance.
