Metal Finishing Barrel Apparatus Abstract A barrel loading and unloading station that in- cludes a barrel support stand for supporting a plating barrel in predetermined positions and a door handling apparatus for releasing and separating a barrel access door from the plating barrel. The door handling apparatus includes a door assembly mounted for reciprocating motion towards and away from the plating barrel by a pair of trackways that are mounted to an elevator mechanism that is operative to raise and lower the trackways to increase accessibility to the barrel after the access door has been removed. One embodiment of the door handling assembly includes a pair of rotatable spindles operative to engage and rotate locking knobs on the barrel access door and a slide mechanism for unlatching the door from the barrel. Another embodiment of the door handling assembly includes a plurality of clamp engaging spreader arms opera- tive to spread and release resilient clamps from the plating barrel. Improved barrel door constructions are also disclosed that facilitate the operation of the door handling apparatus. In one embodiment, the improved barrel access door includes a pair of latch members overlying the outer face of a per- forate closure panel which are moved towards and away from each other to release and engage locking structure forming part of the plating barrel. Locking knobs are provided for fixing the position of the latch members relative to the closure panel. In another embodiment, the barrel access door includes resilient clamps fastened to a perforate closure panel , each clamp including structure engageable by the door handling assembly .
