ABSTRACT:
The coke oven cleaner is capable of scraping particularly the entrance areas of a coke oven automatically to remove tar and the like adhered thereon completely, and comprises an upright stationary holding or support frame mounted on a door lifter, and a first scrapers-holding frame movable up and down the stationary holding frame and carrying first scrapers arranged to engage the door sealing surface of the coke oven entrance. A second scrapers-holding frame is movable with the first scrapers-holding frame and carries second scrapers engageable with the interior surfaces of the door frame and with the brick lining of the coke oven. Heat-blocking plates are movable with the first and second scrapers-holding frames. The second scrapers-holding frame comprises a pair of interdependent substantially parallel upright members interconnected by linkages, similar to toggle linkages, for movement laterally toward and away from each other by a hydraulic actuator or the like acting on one of the linkages.
