Abstract

A coal-charging apparatus includes a charging car with charging bins to discharge coal through filling tubes into charging holes in the roof of an oven chamber. A feed-screw conveys coal from the bottom of a charging bin to a trough communicating with a fixed filling tube. A peripheral trough on the bottom of this tube is filled with sand or liquid and receives a peripheral seal lip on the inside of a movable sealing tube. Hooks on the outside and at the top of the movable sealing tube engage a ring that is suspended by bearings at both ends of a stirrup. The filling tube is raised and lowered by a linkage system that includes a lever supported by a platform and operated by a piston and cylinder assembly. A closure plate is operated by a linkage including a lever supported by a platform and engaged with a piston and cylinder assembly. The closure plate is a leading edge that engages below a wall just above the fixed charging tube.

Dependent claims

A coal-charging apparatus adapted to move along the top of a battery of coke ovens wherein the roof for each coking chamber includes spaced-apart charging holes with frames normally covered by lids that are removed to feed a charge of coal into the coking chamber, the coal-charging apparatus including a charging car with charging bins to discharge coal into an oven chamber,

a feed screw to convey coal from the bottom of each charging bin,
a trough communicating with the charging bin for conveyance of coal by said feed screw,
filling tubes carried by said charging car to receive coal from said trough, said filling tubes including fixed and movable tubes for communication with the charging hole after removal of the lid therefor, each movable tube having hooks on the outside thereof and a downwardly-extending seal lip on the inside thereof, each fixed tube having a peripheral trough containing sealant material on the outside thereof,
a support ring to engage the hooks of each movable tube,
a vertically-movable stirrup coupled for pivotal movement about a horizontal axis to each support ring to vertically position the movable tube of a filling tube,
a vertical guide on the outside wall of said trough, and
a linkage guided by said vertical guide for raising and lowering a stirrup.
