Abstract
A coupling for directing a stream of particles falling from a feed spout through an opening on the top cover of the screen box of a screening machine. An upper diaphragm seals the feed spout within the mouth of a funnel. A lower diaphragm seals the funnel discharge opening within the top cover opening. Both diaphragms are flexible and permit the funnel to tilt axially and accommodate movement of the top cover opening with respect to the feed spout. Optionally, a gimble may support the funnel and diaphragms and thereby relieve the diaphragms from the weight of the coupling.
