Abstract
An extendible hopper is mounted to the undercarriage of a pusher machine and is operable to be extended to engage the face of the coke oven battery, between the buckstays and just below the door jamb, to catch hot coke that spills out of coke ovens as the door is removed and the pusher ram is retracted. A bin is also mounted to the undercarriage of the pusher machine to receive the hot coke collected by the extendible hopper. Quench sprays are mounted to the bin to quench the hot coke, and suction means are mounted to the bin to draw off pollutants that emanate from the hot coke and the quench thereof.
