offset upstream and downstream tubes which are hingedly attached one to the other with an upstream end opening of the offset downstream tube being significantly larger than outer dimensions of a downstream end of the offset upstream tube the offset upstream and downstream tubes are rectangular in cross section with each including hinge mounts which extend laterally outwardly from outside surfaces of panels thereof the downstream end of the offset upstream tube terminates in a plane which forms an angle with an axis of elongation of the offset upstream tube the offset upstream tube has a side opening with a ledge and a door thereat application_number US 60763390 A description referring now to the drawings a gravity conveyor chute 10 is affixed to a building 12 having ledges 14 extending from side openings 28 in sections 15 and 16 and tube 18 of the gravity conveyor chute 10 the sections 15 and 16 are tubularly shaped with a downstream end of the upstream section 15 telescoping into an upstream end of the downstream section 16 the sections 15 and 16 can be basically of a type described in u s pat no 4 640 403 to mcdermott however the tube 18 is part of an offset assembly 20 of this invention in this respect the offset assembly 20.
