ABSTRACT:
A lumber sorting apparatus wherein a bin collects graded lumber. Flexible straps across the bottom are extended to expand the lumber holding capacity. One end of the strap has a releasable latch mechanism and latching of the strap (after dumping the lumber) is provided by a rigid pivotal arm that receives the latch mechanism in the rewinding operation and pivots the latch mechanism into place for relatching. The arm member includes a length portion that spans the open bottom. Guide pins in the arm member on either side of the length portion define a straight reach across said length portion which is offset downwardly from the straps whereby lumber pieces dropped into the bin are prevented from impacting the rigid arm member.
