An actuating mechanism for a locking lid, capable of completely clearing an opening in a vessel and which, in the closed position, is flush with the inner wall of the vessel. The actuating mechanism comprises a sleeve which slides over a fixed rod at an angle of between 0.degree. - 30.degree. with the vessel wall. The sleeve carries at spaced points two pivotally mounted, parallel links of equal length which are pivotally connected to the lid. The lid also carries a guide wheel running in a guide track disposed perpendicular to the vessel wall and one pivotal connection between the sleeve and link carries a connecting rod displaced by a crank provided with an actuating lever. In the initial opening and final closing movements, the locking lid moves perpendicular to the wall guided by the guide wheel running in the guide track and after clearing the opening, the lid moves parallel to itself and is brought back in front of the opening.
A vessel having a closable opening in a wall therein, a locking lid recessed in said wall of said vessel, a mobile supporting member for moving the locking lid so as to open and close said opening, a connecting element comprising at least two rods, one end of each of said rods pivotally connected to the locking lid, the other end of each of said rods pivotally connected to said mobile supporting member, whereby when the lid is in a locked position the pivotal points of the rods substantially coincide with the points of a rectangle.
