ABSTRACT:
An apparatus and method for segregating different size articles in which the articles to be segregated are transported along a moving canted conveyor and permitted to slide onto the upper end of an inclined chute which has a divider located substantially parallel to the long axis of the chute. The shape and location of the divider causes the smaller size articles to be directed to one side of the divider and larger size articles to be directed to the other side of the divider. The segregated different size articles then pass to different portions of a second chute which is at a lesser incline than the first chute and this serves to reduce the speed of the articles. The segregated articles are contained in separate portions of the second chute by compact gates which can be individually activated to permit the segregated articles to slide off the lower end of the second chute.
