A classifying machine for sizing articles, separating the articles so sized and delivering those within given size limits to particular bins having a pair of juxtapositioned rollers raised at their feed ends so that they move in part under the force of gravity to their discharge ends. The rollers are each individually adjustable at different ends to taper outwardly of each other from the feed end to the discharge end so that the smallest selected sizes of the articles drop between the rollers in a collection bin at the feed end and the articles of the largest size are discharged at or near the discharge end of the rollers.
