A combined control device for the operation of coke oven batteries which includes both a part for converting from heating with a strong gas to a lean gas, and vice versa, and a part for switching the regenerative heating system from one group of heating flues to another, comprises a support frame on which is mounted a rotary switching control cylinder and a rotary conversion control cylinder in end-to-end relationship and for rotation around the same axis. The rotary conversion control cylinder is displaceable in respect to the rotary switching control cylinder, and the two cylinders may be coupled together for rotation together or the conversion cylinder may be shifted axially so that it will not rotate with the switching control cylinder. The switching control cylinder is driven at one side from a motor driven transmission which also permits the manual operation of the cylinders. A plurality of axially spaced, circumferentially arranged cam tracks are arranged on each of the two cylinders at spaced axial locations along their lengths and in alignment with switching valves that are similarly oriented along the length of the two cylinders.
A combined control device for the operation of coke oven batteries, including both a part for converting from heating from a strong gas to a lean gas, and vice versa, and a second part for switching the regenerative heating system from one group of heating flues to another, comprising a support frame, a single rotary switching control cylinder rotatably mounted on said frame, a rotary conversion control cylinder rotatably mounted on said frame alongside, and concentric with, said switching control cylinder, means mounting said rotary conversion control cylinder for both rotation and axial displacement into and out of engagement with said rotary switching control cylinder, said rotary conversion control cylinder being rotatable with said rotary switching control cylinder when they are interengaged, coupling means for coupling said rotary conversion control cylinder and said rotary switching control cylinder together for combined rotation together, drive means driving at least one of said rotary switching control cylinder and said rotary conversion control cylinder, a plurality of axially spaced, circumferentially arranged cams on said rotary switching control cylinder and said rotary conversion control cylinder a plurality of switching valves for the switching of the regenerative heating system from one group of heating flues to the other arranged in spaced axial location in respect to and alongside of said rotary switching control cylinder in lateral alignment with and of a number corresponding to said cams on said rotary switching control cylinder, a plurality of converting operation valves arranged in spaced axial relationship in respect to and alongside said rotary conversion control cylinder in lateral alignment with and of a number corresponding to said cams on said rotary conversion control cylinder, follower means mounted on said frame engaged with lateral surfaces of respective ones of said cams on said rotary switching control cylinder and with said switching valves for selectively operating said switching valves and engaged with lateral surfaces of respective cams on said rotary conversion control cylinder and with said converting operation valves for selectively operating said converting operation valves.
