Abstract
Abstract An improved spring mount for a vibratory feeder wherein the springs supporting the vibrating rail member from the stationary base member are solidly fixed at one end to one of those members and hingedly secured at their other ends to the other of those members so that the flexure of each spring in operation is a simple one about substantially a single transverse axis near its fixed end, rather than a complex one oppositely about at least two longitudinally spaced transverse axes as is the case when each end of each spring is solidly fixed to its associated member. In the optimum form of the invention, the hinged connections are between the rail and the upper ends of the spring and each such connection includes a rubberoid sleeve or bushing which resiliently yieldably resists the hinging action in either direction away from an equilibrium position.
