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.
Apparatus for conducting dry comminuted material from a bin opening at one level to the opening of a hatch at a given position at a second level including in combination, a frame, an upper conduit, means mounting said upper conduit on said frame at a position to receive material discharged through said opening and for rotary movement around the vertical centerline of said opening, an elongated intermediate conduit, means connecting said intermediate conduit to said upper conduit for swinging movement around a generally horizontal axis, means for moving said upper conduit around said opening axis while moving said intermediate conduit around said horizontal axis so that material slides through said intermediate conduit and whereby the position of the lower end of said intermediate conduit can be described in terms of polar coordinates in a plane of projection in which said end can be moved to a location corresponding to said given position, a pair of lower conduits, means mounting said lower conduits for telescoping movement relative to each other, means connecting one of said lower conduits to the lower end of said intermediate conduit for pivotal movement around a generally horizontal axis, means for moving said lower conduits relative to each other to move the lower end of the other lower conduit into said hatch opening, and a parallelogram linkage mechanism for positively maintaining said lower conduits parallel to said upper conduit.
Apparatus for conducting dry comminuted material from the respective discharge openings of a bin having a preset pattern of discharge openings at a first level to the hatch openings of cars having various patterns of hatch openings including in combination a frame, a plurality of material transfer spout assemblies each of said assemblies comprising an upper conduit, means mounting said upper conduit on said frame at a position to receive material discharged through one of said openings and for rotary movement around the vertical centerline of said opening, an elongated intermediate conduit, means connecting said intermediate conduit to said upper conduit for swinging movement around a generally horizontal axis, means for moving said upper conduit around said opening axis while moving said intermediate conduit around said horizontal axis so that material slides through said intermediate conduit and whereby the position of the lower end of said intermediate conduit can be described in terms of polar coordinates in a plan of projection in which said end can be moved to a location corresponding to the position of one of said hatch openings, a pair of lower conduits, means mounting said lower conduits for telescoping movement relative to each other, means connecting one of said lower conduits to the lower end of said intermediate conduit for pivotal movement around a generally horizontal axis, means for moving said lower conduits relative to each other to move the lower end of the other lower conduit into said one hatch opening, each of said upper conduit and said intermediate conduit and said lower conduits having home positions out of operative association with a car being loaded and from which positions all are moved in the same direction to accommodate care of various types, said apparatus including means responsive to initiation of movement of a car being loaded for actuating said conduit moving means to restore said conduits to said home positions.
Apparatus for conducting dry comminuted material from a bin opening at one level to the opening of a hatch at a given position at a second level including in combination, a frame, an upper conduit, means mounting said upper conduit on said frame at a position to receive material discharged through said opening and for rotary movement around the vertical centerline of said opening, an elongated intermediate conduit, means connecting said intermediate conduit to said upper conduit for swinging movement around a generally horizontal axis, means for moving said upper conduit around said opening axis while moving said intermediate conduit around said horizontal axis so that material slides through said intermediate conduit and whereby the position of the lower end of said intermediate conduit can be described in terms of polar coordinates in a plane of projection in which said end can be moved to a location corresponding to said given position, a lower conduit having a discharge opening adapted to move into said hatch, means connecting said lower conduit to the lower end of said intermediate conduit for pivotal movement around a generally horizontal axis, and a parallelogram linkage mechanism for positively maintaining said lower conduit parallel to said upper conduit.
