Abstract
An assembly for sealing a shaker screen assembly in a shaker separator includes a substantially inflexible gasket affixed to each screen support and a flexible gasket affixed to each screen support such that the screen frame rests atop the gaskets on the support around its periphery. A wedge block retainer bracket is affixed to each side wall of the shaker separator above the corresponding section of the screen frame. A wedge block is selectively drivable into the space between the wedge block retainer bracket and the corresponding section of the screen frame, providing force thereto sufficient to seat the screen frame against the inflexible gasket and to compress the flexible gasket between the screen frame and the screen support, thereby providing a substantially fluid tight seal.
