ABSTRACT:
A shifter mechanism for a filter press, which shifter mechanism incorporates a vibrating mechanism for effecting bumping of individual filter plates during the separation thereof from the closed stack to assist in dislodgement of filter cake from the individual filter plates. The vibrating device can selectively vibrate or bump the individual filter plates responsive to the weight of the filter plate being bumped, whereby the vibrating device will be activated only upon sensing a filter plate having a weight greater than a predetermined value so as to be indicative of an undesired quantity of filter cake being adhered thereto.
