IMPROVEMENT IN REVERSING METHOD AND APPARATUS FOR THE AUTOMATIC HEATING CHANGE-OVER OF A COKE OVEN BATTERY Abstract of the Disclosure A machine for reversing the heating cycle of a coke oven battery includes mechanism to lock out either one of two reversing rods in proper time sequence so that only three of the normal four reversing rods are operable for the selected mode of underfiring of the battery. Shifting or change-over can only be accomplished at the neutral position which occurs when all fuel gas to the battery is shut off. The shifting or change-over initiates the change-over of rich or lean underfiring gas and also is interlocked so that the main drive cannot operate until all change over functions are completed.
