A filter press plate shifter assembly provided with a shifter housing having a center part which passes over the filter plates and housing parts positioned adjacent opposite side rails. The housing parts are rollingly supported on rods which extend along the side rails. One housing part mounts a rotary pneumatic motor and a drive roller which drivingly engages the rod. Each housing part mounts a plate shifter unit having a pneumatic shift cylinder which is provided with relatively fixed and movable plate shifting blades. A pneumatic lift cylinder pivots the shift cylinder upwardly so that the blades project between handles of adjacent filter plates, following which the shift cylinder is energized so that the movable blade engages and shifts the endmost plate toward the open press head. A pressure sensor retracts the shift cylinder and lowers the lift cylinder, and a further pressure signal activates the drive motor to advance the housing to the next position for engagement with the next plate to begin the next plate shifting cycle.

Plate shifter for filter press

A litter container is provided that is particularly adapted for use in urban environments. The litter container comprises an architecturally-styled, substantially cylindrical body which is bolted or otherwise suitably secured to a support surface. An arcuate door is disposed in the cylindrical body, the door comprising a substantially 180.degree. arcuate section of the cylindrical body. A hinge and mounting structure for the door is provided for pivotally mounting and cantilevering the door about a substantially vertical axis. The end of the door opposite the hinge is automatically locked in a closed or latched position by a tamper-proof latch which can only be actuated from the exterior of the litter container by a special key. A corrosion-resistant liner is disposed within the cylindrical body of the container and a chute centered on the axial centerline of the container communicates with the corrosion-resistant liner to direct litter therein. A high-capacity, heavy-duty, extremely durable litter container is thus provided for use in high traffic urban area where maintenance is a problem.
