  • Patent number: 9931672
    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.
