Attorney, Agent or Firm: Striker; Michael J.
A device for opening, closing and cleaning fill holes of a coke oven comprises a self-supporting carrying frame extending above the fill holes and supporting a runway for an overhead crane and further supports spring-biased bell seals for respective fill holes; a manipulation unit is suspended on the crane and includes a vertical thrust drive and a rotary drive coupled respectively to a manipulation head which is driven into engagement with actuation means for respective bell seals to selectively open and close the bell and to rotate simultaneously cleaning knives in each fill hole. |

DETAILED DESCRIPTION What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims: 1.
In combination, a device for opening, closing and cleaning fill holes and a coke oven structure of the type having the fill holes arranged in its top cover and being chargeable by a coal conveyor, each fill hole being provided with a bell seal, a spring for urging the bell seal into its closing position, an actuation member connected to said bell seal, and a pair of juxtaposed cleaning knives arranged on said actuation member in the range of the bell seal for rotation in said fill hole, the device comprising a self-supporting carrying frame extending above said top cover of the oven, a manipulation unit supported on said carrying frame for movement above said actuation members of respective bell seals, said manipulation unit including a thrust-and-turn head engageable with an actuation member, a vertical linear drive for imparting a reciprocating vertical movement to said head, and a rotary drive means for imparting a rotary movement to said head in addition to said vertical movement.
2.
A device as defined in claim 1, wherein said actuation member is a pin guided for reciprocating vertical movement in said carrier frame and having at its upper end a conical tip, and said head being provided with a matching conical recess to engage said tip.
3.
A device as defined in claim 2, wherein said pin further includes radially projecting lugs and said head has corresponding radial recesses in the range of said conical recess to engage and carry said lugs.
4.
A device as defined in claim 1, wherein said linear drive is a hydraulic or pneumatic cylinder-and-piston unit.
5.
A device as defined in claim 4, wherein said cylinder-and-piston unit includes a piston rod provided with a central bore for accommodating a fitting square piece coupled to said rotary drive means.
6.
A device as defined in claim 1, wherein said manipulation unit is supported on a platform movable in all directions on a horizontal plane and being supported on said carrying frame
