ABSTRACT:
A pair of longitudinally spaced valve elements are provided in a pneumatic outlet. Each valve element includes a body portion, preferably a segment of a circle, including a body portion edge which seats on a body portion valve seat located adjacent the body portion edge, and a moment portion extending eccentrically away from the body portion, which seats on a moment portion valve seat. Each valve element is movable to a sampling position in which the body portion is spaced from the body portion valve seat and the moment portion is spaced from the moment portion valve seat to allow lading for sampling to flow into the discharge conduit. Each valve element includes a pair of operating shafts extending in opposite directions from the valve element, parallel to the discharge conduit, through opposite end walls of the outlet. Operating handles are attached to the operating shafts outside the end walls of the outlet. The discharge conduit end caps are held in place with a pair of large headed bolts which are pivotably mounted on the discharge conduit and which engage at least a portion of the adjacent end cap. The large headed bolts are attached to vertically extending locking members of generally inverted J shape which are rotatably mounted on a side of the discharge conduit. In accordance with the present invention, the lower locking surface on a pair of diagonally spaced inverted J bolts is spaced from its respective operating handle a distance sufficient that if the end cap on the near or sampling end of the outlet is removed, the operating handle on the sampling end may be rotated sufficiently to move the valve member away from its valve seat a distance sufficient to take a sample of lading, without removing the end cap on the opposite end of the discharge conduit.
