ABSTRACT OF THE DISCLOSURE A vibratory feeder has an elongated base assem- bly that is supported on a foundation by longitudinally spaced vibration isolators. Projecting upwardly from the base assembly at longitudinally spaced locations are a plurality of leaf springs with upper portions that support a trough assembly. The base and trough assemblies have masses, with the centers of these masses being spaced apart along an upwardly extending axis. The trough assem- bly is driven transversely of the upwardly extending axis by a driver. The assembly masses create inertia forces acting at the mass centers, and these forces form a force couple urging a rotational motion on the feeder as a whole. The leaf springs are arranged to deflect along non-parallel paths to guide the trough assembly in both curvilinear translation and rotation with respect to the base. This rotation opposes the rotational urge created by the inertia force couple to thereby eliminate rotational motion of the trough with respect to the foundation, so that the trough moves only in curvilinear translation with respect to the foundation. -1a-
