Abstract
In a railway hopper car with several bottom dump doors, the doors are operated by a main door operating member in the form of a thrust bar running the length of the car. The bar, when moved, rotates levers which rotate actuator shafts which move door operating linkage arrangements, opening and closing the dump doors. An adjustable positioning structure is provided on each lever to cause adjustment of the individual dump door positions. The adjustment is accomplished by tightening or loosening bolts in the adjustor, which is fixed on an actuator shaft running to the linkage arrangement. The adjustor and actuator shaft rotate on a bearing with respect to the lever, but are held in locked adjusted position by the adjustor bolts abutting on flanges welded to the lever.
