Abstract
Abstract Each of the filter plates is provided with stud members disposed horizontally or vertically on opposite sides. Hook members are pivotally mounted on each filter plate so as to be associated with stud members on the next adjacent filter plate. A release arm formed on the actuating member and adapted to be engaged with a tail member of the hook member is associated with a release pin on the preceding filter plate so that when the preceding filter plate is separated from the following adjacent plate the actuating member on the following plate is forced to operate to release the hook member thereon from the stud member on the next filter plate.
