Abstract
A pneumatic hopper discharge outlet is fastened to the bottom of railway hopper cars for controlling the discharge of lading. The outlet includes a pair of side walls, a pair of sloping side walls, and a valve shaft which is rotatably mounted in the end walls and extends longitudinally between the side walls. An eccentric valveshaft mounting is disposed on each end wall for rotation about a valve shaft mounting axis and includes a valve shaft receiving bore disposed eccentric to the valve shaft mounting axis. By rotating the eccentric valve shaft mounting, the lateral position of the valve shaft relative to the side walls is adjusted. Lading which has passed the valve shaft is received in a trough and is conveyed through a transition tube to conventional pneumatic off-loading equipment. In transit, the transition tube is closed by a closure cap assembly. This closure cap assembly includes a closure cap loosely pivoted about a pivot axle on the transition tube as well as means for adjustably locking the closure cap in a closed position.
