Abstract
A conveyor element tensioning mechanism which is formed by a pair of like tensioning supporting opposite ends of an idler roller. The tensioning devices each include a slide member with a cylindrical pin which is supported within a cylindrical guide opening. The cylindrical pins have a studs extending radially therefrom which extend through a radially opening slots formed along the lengths of the guide openings in order to prevent the cylindrical pins from rotating. The studs support manual operators which may be actuated to move the slide members into a conveyor element tensioning position. During actuation, the manual operators engage an adjustably positioned reference surface so that the resulting tension in the conveyor element may be easily altered.
