"COOK OVEN DOOR SYSTEM, METHOD FOR REDUCING AIR EXHAUST THROUGH A COOK OVEN DOOR OPENING, CRACK DOOR MECHANISM TO SEAL A COOK OVEN DOOR AND SYSTEM FOR SUCH MECHANISM ". It is an oven door latch system for a coke oven door that can be positioned within an oven door opening and a method of sealing a coke oven. The door latch system includes a rotatable member rotatably attached to the oven door. The rotating member has an arched wedge-shaped coupling edge for varyingly coupling with a precursor plate on a knocker member adjacent the opening of the oven door when the oven door is disposed at the oven opening. A tab member is also added to the rotating member. A remotely operated adjusting actuator is employed to engage the flap member to rotate the rotary member in conjunction with an oven door opening or closing operation. An increased oven door seal is achieved by the rotary wedge latch system.
