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 The apparatus has a support which can be inserted into and withdrawn from the chamber opening.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edge of the tool engages the bottom wall of the coke oven chamber to scrape away deposits therefrom as the support is withdrawn from the chamber opening.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.
