ABSTRACT:
A coke oven construction for the fastening of furnace door frames to the armor of horizontal, blockwise arranged coke oven furnaces, comprises a furnace which has an armor plate with a portion offset inwardly toward the furnace which carries a furnace frame which is sealed to the armor plate. A metal plate overlies the portion of the armor plate which extends outwardly from the frame and it has an edge which projects from the armor plate in a direction toward the frame. A hooked member is engaged over the edge of the plate and an eye bolt is threaded into the hooked member and provides a bolt for the pivotal mounting of a toggle which has one arm which bears against the frame and another arm which extends upwardly alongside an anchor stand which is mounted over the plate of the armor. A pressure plate is positioned between the anchor stand and a set screw or bolt member which is extended through the second arm portion of the toggle and it may be adjusted to vary the pressure acting on the second arm to force it outwardly from the anchor stand and the first arm into engagement with the frame member.
