ABSTRACT:
A filter press cloth hanger for a filter press comprising two arms joined at their upper ends by a pivot bolt which extends through platelike members welded to the tops of the arms. Each arm is similar in construction and comprises the hollow tubular outer wall in which slides a spring loaded rod. The rod carries at its lower end outside the arm a latching plate, which has a keyhold aperture, designed to fit over the end of a suspension member for a filter plate. The rod carriers at its free end within the hollow tubular outer wall, a stop member, which is screwed to the end of the rod and prevents the rod from being completely withdrawn from the tube. The stop is also profiled to prevent rotation of the rod within the arm and bears on one end of a compression spring which biases the rod in the arm. The pivot bolt carries a roller, which can run along a support bar, extending the length of the side bar filter press on which the hanger is to be used. The latching plate at each arm is fitted onto a support rod comprising the suspension member for each filter cloth and this rod is recessed in a manner so that the recess fits into the lower part of the keyhole aperture of each latching plate. This filter press cloth hanger may be used to support filter cloths on either side of a filter plate or filter cloths between two adjacent plates.
