Abstract

Abstract First and second compound chutes constituting a collecting chute assembly each comprises an outer chute of inverted, bisected frusto-conical shape having a semicircular upper opening and a semicircular lower opening, and an inner chute of inverted, bisected conical shape disposed within the outer chute via a partitioning plate. The overall chute assembly is of inverted frusto-conical shape and is constructed by uniting the compound chutes by bringing their respective partitioning plates into face-to-face contact, the assembly defining two discharge routes. At the lower ends of the chutes, one discharge route communicates the inner chute of the first compound chute with the outer chute of the second compound chute, and the other communicates the inner chute of the second compound chute with the outer chute of the first compound chute. Weighed articles introduced into the inner chute of one of the compound chutes will be guided into the outer chute of the other compound chute to join weighed articles introduced directly into the outer chute, the combined articles being discharged from said outer chute to a point outside the system. The arrangement is such that time required for articles to be discharged from both discharge passages is approximately the same.
