Abstract: An apparatus for separating objects according to size including conveyor means having an endless conveyor belt trained over a supporting surface and mounted on a frame with its transverse dimension disposed at a slope to the horizontal. A plurality of endless sizing belts are arranged in side-by-side, spaced apart relationship with each sizing belt including a run which extends above and longitudinally of the supporting surface. The distance between the sizing belt runs and the supporting surface varies from a maximum distance adjacent the uppermost edge of the conveyor means to a minimum distance adjacent the lowermost edge of the conveyor means. Means are provided for driving the conveyor belt means and the plurality of sizing belt means to the end that objects placed on the sizing apparatus adjacent the uppermost edge of the conveyor means are sorted according to size and discharged from the opposite end of the supporting surface at a location varying according to size.
