Abstract

An oven door latch system for a coke oven door positionable within an oven door opening and method of sealing a coke oven. The door latch system includes a rotary member rotatively attachable to the oven door. The rotary member has a wedge-shaped, arcuate engagement edge for variably engaging a striker plate on a buck stay member adjacent the oven door opening when the oven door is disposed in the opening of the oven. A tab member is also included on the rotary member. A remotely operated adjustment actuator is provided for engaging the tab member to rotate the rotary member in conjunction with an oven door opening or closing operation. Enhanced oven door sealing is provided by the rotary wedge latch system.
