ABSTRACT:
An apparatus for charging coke ovens with coal through filling openings in the coke oven roof comprises a hopper support which advantageously comprises a car undercarriage which is movable into position over an associated filling opening. At least one charging hopper is supported on the support for upward and downward movement and it has a lower end with a discharge connection which is engageable into the filling opening of the coke oven. The support carries a guide for the upward and downward movement of the hopper which is connected to a drive motor in the form of a fluid pressure operated piston and cylinder combination. In one embodiment a compression spring supports the hopper in a fully loaded position and the drive motor which is connected to the hopper must overcome a slight compression force of the spring to move the hopper downwardly to engage the discharge connection into the coke oven opening. In another embodiment the spring pressure does not become effective until a drive connection engages onto a compression spring during the course of its movement with the hopper in a downward direction to further compress the spring toward the end of the downward movement. The construction also includes a separate drive motor for opening and closing a valve in the discharge connection for regulating the discharge of the coke from the hopper into the oven.
