Abstract

An apparatus for cleaning the top or bottom horizontal section of a coke oven door seal ring and which applies approximately constant pressure to all points along its lateral path. A cleaning head is pivotally mounted on the terminal end of an arm member which is, itself, pivotally mounted to oscillate in a horizontal arc on a base structure. An extension of the door cleaner frame is suspended above the arm and on this frame there is mounted a spring. A vertical, spring driven link is attached at its upper terminal end to this spring and at its lower end to the base. This link is also medially attached to the frame so as to pivot in a vertical arc about this point of attachment. A second idler link which is pivotally connected at its top to the frame and at its bottom to the pivoting base keeps the cleaning head from being vertically displaced out of contact with the seal ring.
