Abstract
A linear vibratory feeder having a base, an overlying track support plate and a counterweight with an internal structure between the base and support plate and a pair of outer side plates secured to each of a plurality of separate, longitudinally spaced parts of the internal structure. A first pair of vertical, relatively flexible, flat leaf springs extend between the base and internal structure and a second pair of generally upright but slightly inclined, flat leaf springs extend between the internal structure and support plate. The first and second pairs of leaf springs are mounted in overlapping relationship to provide a low profile feeder and a short moment arm between the centers of gravity of the upper support plate assembly and counterweight.
