Abstract
Disclosed is a clamp for securing the top cover of a screening machine. Clamping is not subject to galling or seizing and the force exerted is not temperature or displacement dependent. The clamp is air pressure operated, with super-atmospheric pressure being applied for clamping and venting to atmosphere or sub-atmospheric pressure being applied to release the clamp. The clamp is mounted for easy swing away movement when not in use so as to permit the top cover to be removed. Multiple clamps may be simultaneously operated from a common manifold.
