ABSTRACT:
Sizing screen apparatus is provided with mechanism for enabling the extent of spacings, longitudinally of an elongate sizing screen between transversely extending, individual rows of spacing members, to be adjusted individually. Each transversely extending row of sizing members is mounted on a rotatable shaft journaled at its opposite ends in the lower end portions of a pair of mounting arms that are pivoted at their upper end portions to opposite longitudinal side members of a supporting frame and hang downwardly for back and forth space adjusting movement. The mounting arms of the pair are pivotally interconnected adjacent their lower ends with an elongate connection member of an operating device that is manually or power operated. The connection is made by preferably a pair of rods at opposite sides, respectively, of the sizing screen and having one set of corresponding ends pivotally attached to the respective mounting arms of the pair and the set of opposite ends fixedly attached to the connection member of the operating device in a length adjustable manner, as by providing such opposite ends with screw threading, passing them through respective bracket members of a series of same that are immovably affixed to the connection member, making the lengthwise adjustment by screwing a set of lock nuts at opposite sides of such bracket members, and tightening such lock nuts to lock the adjustments in place.
