Abstract: The invention is concerned with an apparatus for scraping the bottom wall of a coke oven chamber adjacent the chamber opening so as to remove deposits which would otherwise prevent the sealing insertion of the chamber door into the opening. The apparatus has a support which can be inserted into and withdrawn from the chamber opening. A scraping tool is mounted on the support so that it can pivot between an upwardly tilted position which it assumes as the apparatus is being inserted into the chamber opening, and a downwardly tilted position in which a horizontally extending scraping edge of the tool engages the bottom wall of the coke oven chamber to scrape away deposits therefrom as the support is withdrawn from the chamber opening. A biasing arrangement biases the scraping tool into engagement with the bottom wall when the scraping tool is in the downwardly pivoted position.

Abstract: The apparatus for cleaning the horizontal sealing surface of the coke oven door includes a cleaning tool that is arranged to move horizontally on a tool support. The tool support is movably connected to the frame member and is arranged to be adjusted vertically to clean the horizontal surface of the coke oven doors having different vertical dimensions. Stop members are provided on the tool support and the frame to control the vertical adjusted position of the cleaning tool. The apparatus also includes cleaning tools for cleaning the vertical edges of the coke oven door. The latter cleaning tools are mounted on a rotary column which, in turn, is supported on the frame member. Pairs of cleaning tools are connected to the rotary column and are arranged to clean the vertical surfaces of coke oven doors having different transverse dimensions. There are also provided other cleaning tools mounted on rotary columns for cleaning the refractory lining of the coke oven door.
