Abstract

A method and device for evenly distributing granular material such as plastic pellets into a railway hopper car to reduce the valley angle, eliminate void spaces, and increase the volume of material in each hopper. A cone-shaped deflector is placed in line with each hatch opening at a point below the roof line. The deflector directs material horizontally away from the hatch opening to reduce and virtually eliminate the valley angle for most granular materials. The cone is hung from support struts which may be suspended from an angular mounting ring which is mounted atop the hatch coaming.
