  • Patent number: 4964348
    Abstract: A pivoted drop end for a railway car which is adapted to be manipulated (lifted) by power equipment in the car to open or close the car end. The car end includes lower side posts, each having a cam follower running in a cam on the car frame which swings the car end about a pivot carried on each of the posts. The pivots are guided in a vertical slot and cooperates with the cam. The car end is opened outwardly of the car and rests in open horizontal position on a pedestal support of the frame so that adjacent open car ends form a bridge to move loads longitudinally of the train. The car end is dampened in lowering (opening) movement by dash-pots connected between the car end and car frame. A side dumping railway car tilts the car body to either side by sets of pneumatic cylinders, each set being alternatively under control of a valve.
