A device for automatically detaching and/or loosening coke within a coke oven chamber, particularly such a chamber of the type having an inclined or obliquely extending floor, includes a track support adapted to be mounted at a position confronting the coke removal opening of the coke oven chamber. An elongated poking bar is supported by the track support and has at a first end thereof a stoking or broaching head for abutting or scraping coke within the chamber. A trolley is mounted on the track support for movement therealong, and the poking bar is pivoted to the trolley. A reversibly operable cable drive moves the trolley and thus the poking bar along the track support from an initial position whereat the poking bar is positioned outside of the chamber to an operative position wherein the broaching head of the poking bar is inserted into the chamber to abut against coke therein. The poking bar is guided during the movement thereof to follow a predetermined displacement path such that the poking bar will avoid obstructions such as a quencher car located outside the coke oven chamber, such that the broaching head will be passed through the coke removal opening of the chamber even when the chamber door is only partially opened, and such that the broaching head will be positioned on the floor of the chamber. Movement of the poking bar thereafter will be guided by sliding contact of the broaching head on the floor, and possibly on the side walls, of the chamber.
