A filter plate press or an electrolyzer cell has a series of filter plates or cell frames, respectively, which are moved as a stack against a press or cell headpiece by a follower moved by one or more rodded cylinders mounted on a fixed bracket. Scissors mechanisms extending on each side of the press/cell holder and between the bracket and follower assure precise parallel movement of the follower with respect to the headpiece. To accommodate any cumulative errors in the stack dimensions the scissor mechanisms are disengageable upon closure of the press/cell holder so that the follower has freedom to match the abutting surface of the plate/cell frame stack and thus evenly seal the abutting peripheral edges of the plates/cell frames. A pair of plate pawl-containing carriages mounted on a pair of synchronized lead screws extending parallel to a pair of plate/cell frame guide rails on the press are provided to assure simultaneous pick-up of opposed handles of each plate/cell frame being moved for cake discharge or plate/cell frame washing.
In a press for holding a stack of filter plates/cell frames, said press comprising a pair of spaced parallel side rails, a fixed bracket, a movable follower for closing and sealing said stack against a fixed head piece, and at least one closing cylinder on said bracket and having an associated piston rod extending between said bracket and said follower;
