ABSTRACT:
A device for sorting small articles by size. A chute conveys the articles. A gap allows articles of less than a prescribed size through it. The gap is between the chute and a mechanism that extends across the slide. The mechanism detaches and conveys larger articles away along the gap. The object is to prevent articles from becoming jammed upstream of the gap. The gap is a channel that extends essentially across the slope of the chute. The channel is demarcated by two baffles. One baffle merges into the chute. The other merges into the detaching and conveying mechanism. The mechanism also has means of intermittently lifting or tossing articles that become jammed upstream of the channel.
