An array of an assembly of spouts for translating comminuted dry material from a bin having a number of output openings to various railway cars, respective ones of which have hatch openings of different relative dispositions and of different heights while inhibiting pollution of the ambient atmosphere by the material, in which each assembly comprises an upper section pivotally connected to the bin outlet for movement around a vertical axis, a lower section comprising vertically telescoping members, one of which carries a shroud adapted to make a seal with the car hatch, and an intermediate section pivoted to each of the upper and lower sections, together with means for driving the upper section to pivot the entire assembly over a limited arc around a vertical axis, means for swinging the intermediate section around a horizontal axis, while positively maintaining the lower sections substantially vertical, and means for moving the lower telescopic sections relative to each other, all of these movements being designed to accommodate the variety of cars for which the array is to be used. The system readily lends itself to automation. It is provided with means for minimizing the danger of injury to workers in the region of the installation. In addition, the spout assemblies are adapted to be moved to positions at which they permit the locomotive to move through the space under the bin without interference with the spout assemblies.
