Abstract

Abstract A collecting chute assembly including first and second compound chutes. The first and second compound chutes have an outer chute of inverted, bisected frusto-conical shape with 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.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 195 words
An apparatus for collecting articles, comprising: a first compound chute including a first outer chute having an upper opening and a discharge opening, a first inner chute, said inner chute being disposed within said outer chute and a first partitioning plate having a first through hole in communication with said first outer chute and a second through hole in communication with said first inner chute; a second compound chute including a second outer chute having an upper opening and a discharge opening, a second inner chute, said inner chute being disposed within said outer chute, and a second partitioning plate having a third through-hole in communication with said second outer chute and a fourth through-hole in communication with said second inner chute, said first compound chute and said second compound chute being connected so that said first through-hole and said fourth through-hole are in communication and said second through-hole and said third through-hole are in communication; a first discharge chute having an upper opening in communication with said discharge opening of said first outer chute; and a second discharge chute having an upper opening in communication with said discharge opening of said second outer chute.
Claim 2
Independent Claim 195 words
An apparatus for collecting articles, comprising: a first compound chute including a first outer chute having an upper opening and a discharge opening, a first inner chute, said inner chute being disposed within said outer chute and a first partitioning plate having a first through hole in communication with said first outer chute and a second through hole in communication with said first inner chute; a second compound chute including a second outer chute having an upper opening and a discharge opening, a second inner chute, said inner chute being disposed within said outer chute, and a second partitioning plate having a third through-hole in communication with said second outer chute and a fourth through-hole in communication with said second inner chute, said first compound chute and said second compound chute being connected so that said first through-hole and said fourth through-hole are in communication and said second through-hole and said third through-hole are in communication; a first discharge chute having an upper opening in communication with said discharge opening of said first outer chute; and a second discharge chute having an upper opening in communication with said discharge opening of said second outer chute.
Claim 3
Dependent Claim 70 words
An apparatus according to claim 1, wherein said first and second outer chutes have an inverted, bisected frusto-conical shape and a semicircular upper opening, wherein said discharge openings are semicircular, wherein said first and second inner chutes have an inverted, bisected conical shape and a semicircular upper opening and wherein said first and second compound chutes are connected so that the two inverted, bisected frusto-conical chutes form an inverted frustum.
Claim 4
Dependent Claim 40 words
An apparatus according to claim 1, wherein said inner chutes of said first and second compound chutes have an upper opening and said upper openings of said inner chutes and said upper openings of said outer chutes are concentrically arranged.
