Abstract: A grain distributor assembly for a grain elevator which includes a manifold plate having a plurality of discharge openings connected to respective downspouts. A distributor elbow having an inlet at its upper end coaxial with the central axis, and an offset outlet at its lower end, is arranged to discharge into any one of the discharge openings. Mounted below the elbow and swingable with it is a closure disc seated upon the manifold plate and having a single window therein providing passage for the lower end of the elbow. The remainder of the disc seats upon and closes off the inactive, non-registering ones of the discharge openings. A selector is provided for swinging the closure disc and elbow in unison about the central axis for positioning the elbow and window in angular register with a selected one of the discharge openings while maintaining all the other such openings securely covered.

Abstract: A method and apparatus which are particularly adapted for use in the selective and coordinated abstracting of samples to be examined. Essentially, the selector apparatus which has a support means may embody delivery means, receiving means, collection means, and control means. In a preferred embodiment, the receiving means is operatively connected to the support means and includes a plurality of receptacles for receiving flowable material. The delivery means is supported by the support means and may include at least one, but, desirably a plurality of, movable delivery members which carry flowable material therethrough. Each delivery member is selectively movable between a first position and a second position.
