Abstract
An apparatus for uniformly pressing a plurality of flat plate-type structures together comprising a first and second vertical support means, a pair of side rails spaced apart and supported on the support means, the side rails being perpendicular to the support means and adapted to support flat plate-like structures, a plurality of flat plate-like structures with hanger members to slidably and pivotably mount the structures on the side rails, a vertical mobile platen provided with top and bottom hanger members connected to a press means adapted for pressing the mobile platen against and toward the flat plate-type structures to compress them together and retracting the mobile platen from the plate-like structures, the press means comprising at least one coiled spring, a first contactor plate attached to the mobile platen and a second contactor plate attached to a positioning device secured to one of the support means and a first and second guide chamber for directing the positioning device and coiled spring perpendicularly to the face of the mobile platen and the support means useful to form a plate-type pressure apparatus useful as electrolytic cells, filter presses, injection molding apparatus and the like and a novel method of isolating plate-like structures for repair or replacement.
