Patent ID: 7735633

Claim:
A linear vibratory feeder comprising: a feeder chute having a first end for a conveyable material to flow out thereof in a first direction and a second end for the conveyable material to flow out thereof in an opposite direction; a chute base attached to the feeder chute; a first linear vibrator; a second linear vibrator; a first vibrator support suspended from the chute base and a second vibrator support independent of said first vibrator support suspended from the chute base with said feeder chute, said chute base, said first linear vibrator, said second linear vibrator, said first vibrator support and said second vibrator support comprising a linear vibratory feeder having a center of gravity wherein the first vibrator support is attached to said feeder chute with said first vibrator support having a first cross member and a second cross member with said first cross member secured to the second cross member through a set of four elongated axial rigid leaf springs, said first linear vibrator having an axis of oscillation extending toward the center of gravity of the linear vibratory feeder with said first linear vibrator secured to said first cross member and the second cross member secured to the chute base to enable said first linear vibrator to transmit first axial vibrations to said chute through a rigid axis of each of said leaf springs, and said second linear vibrator having an axis of oscillation extending toward the center of gravity of the linear vibratory feeder with said second linear vibrator attached to said chute base through said second vibrator support with said second linear vibrator transmitting second axial vibrations to said feeder chute along the axis of oscillation of the second linear vibrator wherein the axis of oscillation of the second linear vibrator extends toward the center of gravity of the linear vibratory feeder with the axis of oscillation of said second linear vibrator located perpendicular or substantially perpendicular to the axis of oscillation of the first linear vibrator with said first vibrator support and said second vibrator support so that the operation of the first linear vibrator does not affect the second linear vibrator and vice versa to enable the first linear vibrator to direct material along the first direction of the chute and the second linear vibrator to direct material along the opposite direction of the chute.
