A system for mechanically shifting and cleaning the filter plates in a pressure-type filter press wherein the filter plates, which are supported on the side rails of the filter press and have supporting brackets extending over each of the rails, are shifted apart to allow a plate scraping mechanism to move downwardly against the plates and scrape the accumulated filter cake from the filter plates. The plate shifter and scraper are mounted on a carriage which slides along the rails of the filter press and the plate shifter includes pneumatically operated plate shifting devices to separate the filter plates. Once the plates are separated, a scraper mounted on the carriage in pendulum fashion above the plates is extended between the separated plates to scrape the accumulated filter cake from the exposed faces of the filter plates.
