483,444. Separating solid materials. LESLIE, G. M. July 29, 1937, No. 20976. [Class 117] Fruit-grading apparatus comprises two or more superposed horizontal apertured trays slidable horizontally in an enclosing framework, the apertures in the successively lower trays progressively decreasing in size and increasing in number so that the apertures in successive trays are staggered. In the form shown, a number of metal trays 1 with stamped out apertures 7 decreasing in size towards the lowest tray are slidable on guides 2 in the framework 3. Stops 5 are provided to prevent removal of any except the upper trays and thus prevent interchange of the trays.
