Abstract
A larry car, a quenching car, a pusher and other such accessory machines travel along the length of a coke-oven battery. Each coke oven is provided with coded structure absolutely indicative of the oven-number of the oven within the battery. The travelling accessory machines are provided with code readers which sense the coded structures and transmit oven-number feedback signals to a central control station. The travelling machines also transmit operation-completed signals upon completion of the individual operations of charging, pushing and the like. A programmed control system at the control station transmits travel-command and operation-command signals in preprogrammed sequences, but the transmission of these command signals is dependent upon the reception of predetermined feedback signals, which establish interlocks serving as conditions precedent to the travel of accessory machines and to their performance of individual operations.
