Coke-oven filling system

Abstract

A filling system operating with an apparatus for loading coal into the charging hole of a coke oven has an upper feed tube, an intermediate feed tube, and a lower tube. The upper tube is connected to the apparatus and is adapted to receive coal from it. The intermediate upright tube is vertically telescopable on the upper tube and has a lower end, with a bellows-type cuff interconnecting the upper and intermediate tubes to prevent leakage from therebetween. The lower tube is pivoted and suspended on the intermediate tube and is alignable with this intermediate tube so that its lower end can sealingly engage over a charging hole in a coking oven and its upper end can sealingly engage with the lower end of the intermediate tube. The intermediate tube can be limitedly vertically displaced and the lower tube can be pivoted out from beneath the intermediate tube so that the filling system has clearance and can pass over the structure on top of the coking oven.
