Abstract
An adjustment means for the slats of sieves and chaffers comprising a manually operable screw mounted on a mounting plate fixed to the chaffer frame and directly connected with the conventional slotted bar for oscillating the slats to clean them and for setting their operating angular position, the screw being normally held on the mounting plate against non-rotative axial movement but releasable for back and forth axial movement to open and close the slats for cleaning purposes; the mounting plate including a latch adapted to engage a noncircular element fixed on the screw to prevent its inadvertent rotation, whereby after being released for operating the slats without rotation the screw is returned to the mounting plate for engagement of the latch, the slats will be positioned precisely in their initially set operating position.
