Abstract
An evacuable vessel having a heavy cylindrical wall seated on a generally square base has a heavy cover hinged at one end to a hinge support attached to the wall. The cover is bolted to the wall in the closed position and sealed by an O-ring. The hinge bolts are seated in a slotted hole to allow the cover to pivot about the O-ring when closing. Adjustable set screws may be used to tighten the hinge arms and introduce a selected degree of friction. Springs are connected between the outside end of each hinge arm and the base.
