Abstract: A stack of interfitting sieve trays are held in position on a carrier by an upstanding periperial wall on the carrier which engages the lower portion of the lower sieve tray, and by a plurality of clamp-down units which at their lower ends are pivotally connected to end portions of the carrier and at their upper ends include a lever operated hook mechanisms for engaging upper edge portions of the top sieve tray. Side edge portions of the carrier are provided with upper and lower bearing strips. These edge portions are received between upper and lower sets of cam rollers which are mounted onto web portions of side members which have been fashioned from channel stock. The side members carry bearing strips which contact and guide the side edges of the carrier. The clamp-down units are overweighted on their outer sides so that when released they will fall outwardly against stop means for limiting the amount of outward movement.
