Abstract
An apparatus for effecting the separation of filter plates within a filter press is disclosed. The apparatus includes a guide track having mounted thereon a slidably reciprocal carriage. The carriage includes at least one pivoted pawl having an abutment space defined thereon for contacting a filter plate to be transported. The pawl is held in a raised orientation by a resilient spring means. The carriage is driven along the guide track by means of a pressure displaced piston mechanically associated therewith. The piston is housed within a tubular member. Positioned within the tubular member are two pressure chambers, one on each end of the piston. Pressurized fluid is controlledly introduced into one or the other of those chambers to effect a displacement of the piston. The pressure cylinder is of the type generally designated a rodless cylinder.
