Abstract
An apparatus, system and method for fastening a screen has a screen with apertures sized to separate a first sized material from a second sized material. A box is positioned beneath the screen in a bracket extending along the screen. A protrusion extends from the box toward the screen. A triangular tensioning element secured along a length of the screen moves in a direction substantially perpendicular to the length of the screen in response to contact with the protrusion to seal the screen against the bracket and tension the screen.
Claims19
An apparatus comprising:
- a screen having apertures sized to separate a first sized material from a second sized material;
- a box positioned beneath the screen in a bracket extending along the screen;
- a protrusion extending from the box toward the screen;
- a triangular tensioning element secured along a length of the screen wherein the triangular tensioning element moves in a direction substantially perpendicular to the length of the screen in response to contact with the protrusion to seal the screen against the bracket and tension the screen;
- and
- a ridge extending along the bracket wherein the ridge guides the triangular tensioning element.
