Abstract
A filter press with filter plates slidable individually by a transport element has on each filter plate a locking hook which cooperates for locking with a locking bolt of the adjacent filter plate. A pivotable blocking element, which in the blocked position, positively blocks the locking hook locking this filter plate against unlocking and is connected to an actuating member which projects into the path of the transport element so that immediately before the latter takes along the relevant filter plate it engages the actuating member and thus pivots the blocking element into a release position so that the filter plate is separable after release of the locking hook. Each respective filter plate to be slid thus remains positively locked to the as yet unopened plate stack until immediately before it is taken along by the transport element and cannot become separated from the stack accidentally. The blocking element is preferably in the form of an arm of a double-armed lever and is swingable downwardly by its own weight. The other arm of the double arm lever is an actuating member which precedes a driver for the filter plate to be engaged by the transport element.
