Abstract: An improved gate assembly and gate control assembly for operatively controlling the movement of the gate assembly in material discharging equipment is provided wherein the gate assembly comprises a first and second clamshell gate member, a connecting assembly for pivotably connecting the first and second clamshell gate members to the equipment and substantially synchronizing the movement of the first and second clamshell gate members between a closed position, and an open position, a gate moving assembly operably connected to the first and second clamshell gate members for moving the first and second gate members between the closed and the open position, and the gate control assembly operably connected to the gate moving assembly, the gate control assembly selectively activating the gate moving assembly such that the first and second gate clamshell members are moved between the closed position and the open position.

Abstract: A reversible push block-rear bumper assembly for attachment to a motor vehicle is provided in which a support unit having a forwardly inclined downwardly extending surface is secured to the underside of a vehicle in close proximity to the rear end of the vehicle. A block unit having an upper incline surface which can be mated with the forwardly incline downwardly extending surface of the support unit is also provided, such surfaces being adapted so that when the block unit and support unit are secured together, the block unit will either extend downwardly from the support unit in a plane substantially perpendicular to the longitudinal plane of the vehicle and thus function as a bumper or, upon rotating the block unit 180.degree. into a reverse position, the block unit will extend outwardly from the rear end portion of the vehicle for use as a push block. An extension unit for modifying the length as well, as the angular relationship of the block unit to the support means, is also provided.
