ABSTRACT:
A device for drop-sorting timber comprises a series of hooks for carrying timber pieces and a conveying system for advancing the hooks to drop positions over timber compartments. The hooks can be pivoted at selected positions to drop their timber pieces and are so formed that while being advanced the open end of a hook is effectively closed by the next following hook to prevent premature discharge.
