A filter press consisting of plates with a gridiron surface alternating
with hollow frames, all of which are held by means of lugs, on the press
framework. The corners of both frames and plates are cored to make
continuous passages for pulp and solution; the filter cloth is placed over
the plates. The pulp passageway connects with the large, square opening in
the frame; the solution and passageways connect with the gridiron surface
of the plate. The Dehne and the Merrill are well-known types.
