ABSTRACT:
In a refuse compaction/ejection system, an improved ejection door having a lower hinged member which reduces the degree of door extension required to obtain an effective open discharge path and a catch-lock means for guiding and retaining the hinged member into closed configuration when the door is in the unextended position. The lower door member is hinged to an upper member which travels a fixed upward path during ejection operations. As the hinged member is carried upward by the upper member, the lower lip of the lower member is withdrawn from the catch-lock means, permitting rotation in an axial rearward direction about the hinge due to the force of discharging refuse. With the refuse ejected, the hinged member returns to its nonrotated natural position, causing the lip of the lower hinged member to catch in rearwardly extending catch-lock means upon the retraction cycle.
