Abstract
An actuating system for operating the doors of a railroad hopper car. The mechanism includes an air cylinder which is coupled to a first lever that is fixed on a shaft. The shaft is coupled to a second shaft through a pair of levers. Supplying air to the cylinder causes the first lever to rotate the shaft which causes the second shaft to rotate. The doors of the hopper are coupled to the two shafts, such that when the shafts rotate, the doors open from the hopper.
