ABSTRACT:
A lumber sorting apparatus wherein a bin collects graded lumber. Flexible straps across the bottom are elongated to expand the lumber holding capacity. One end of the strap has a releasable latch mechanism and latching of the straps (after dumping the lumber) is provided by a rigid pivotal arm that receives the latch mechanism in a rewinding operation and pivots the latch member into place for relatching. The latch mechanism consists of a spool that fits between sleeve portions through which a pin is controllably inserted and withdrawn by a manually operated air cylinder.
