Abstract: A side tensioning assembly for retaining screen media to the side plates of a vibrating-type screening machine includes a support structure for supporting the screen media and a tensioning rail mountable to at least one side plate. At least one bolt assembly is provided for fastening the tensioning rail to at least one of the side plates. Each bolt assembly including a bolt connectable to the tensioning rail, at least one of side plates and at least one bolt engaging structure on a surface of the side plate. Each bolt engaging structure includes a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position.

Abstract: The present invention relates to side tensioning assemblies for retaining screen media to the side plates of a vibrating-type screening machine. The side tensioning assembly includes a tensioning rail and at least one angle box mountable to a side plate. At least one bolt assembly provided for fastening the tensioning rail to the side plate and to angle box. Bolt assembly is provided with is a shoulder bolt that is secured to a terminal end of the bolt. The angle box includes an aperture sized to allow the bolt assembly passage therethrough, and a movable plate with a cutout. The cutout is sized larger than the bolt but smaller than a nut. The movable plate has a bolt-securing position and a bolt-releasing position to allow access to the aperture in the angle box such that the bolt assembly can be detached from the angle box without being disassembled.
