Abstract
A mechanism for attaching a trough on top of a base of a vibratory feeder adapted to vibrate in a specified direction includes a pair of mutually engageable couplers, one attached to the bottom surface of the trough and the other attached to the top surface of the base. Either one of them is protruding and the other is indented such that the former can be tightly inserted into the latter. The protrusion and the indentation of these couplers are so oriented with respect to the direction of vibrations of the base that the total force on the coupler attached to the base obtained by vectorially summing the force of vibration acceleration and the load of the trough will always have a component in the direction in which the protrusion and indentation of the couplers are oriented so as to keep these couplers engaged together. The direction of the protrusion and indentation is substantially perpendicular to the direction of vibrations of the base such that the vibrations of the base can be efficiently propagated to the trough.
