Abstract: A quenching car from coke ovens that serves to receive a carbonized batch from an oven chamber while standing still and is capable of travel alongside a battery of coke ovens to a point under a quenching tower, includes a coke receptacle which is designed as a rectangular box. The receptacle is equipped with a slanted bottom that slants down toward a coke ramp that lies on a side of the car opposite the battery of coke ovens. A front wall of the receptacle facing the coke ramp, is equipped on its lower portion along its entire length with a flap that swings outwardly and which can be pivoted by means of an operating rod and a first operating device from a position in which it holds the receptacle tightly closed into a position in which it is open by the space of a crack in the area of the low point of the slanting bottom. The dump opening of the receptacle meanwhile remains closed by a inner, grate-like flap lining.

Abstract: Means for cleaning the sealing surfaces of coke oven leveling doors and frames, the cleaning means being installed on a coke-pushing machine without any increase in the normal overall length thereof. A carriage extends between and is movable along guideways mounted on the side walls of a surrounding casing, the carriage being provided with liquid nozzles adapted to be directed at the sealing surfaces of the leveling door frame and the sealing surfaces of the leveling door when rotated upwardly. Nozzles are connected through hoses to a supply of high-pressure liquid, the arrangement being such that as the carriage moves along the guideways, high-pressure liquid issuing from the nozzles will clean the sealing surfaces of a leveling door frame and a leveling door when it is rotated upwardly.

Abstract: Apparatus for removing charging hole covers and for cleaning sealing surfaces is carried by a charging car that is movable along an oven roof of a battery of horizontal coke oven chambers. The apparatus includes a support member carried by guides for vertical movement on the charging car. A pivot head is carried by a shaft to pivot about a first axis on the support member. The first axis is inclined at an angle of 45.degree. to vertical. A magnetic gripper is carried by a shaft to rotate about a second axis on the pivot head. A charging hole frame cleaner includes a cleaning tool carried by a shaft to rotate about a third axis on the pivot head. The second and third axes are disposed in a plane at an angle to one another on opposite sides of the first axis and coplanar with the first axis.

Abstract: To hold coke-oven doors so that they may be worked upon, apparatus is provided comprising a frame tiltable from an erect to a horizontal position, that frame having mounted within it a second frame which has two pairs of pockets which receive the ends of the door-lifting beams of the door to be worked upon; means are provided to hold at least one pair of ends of door-lifting beams of the door within pockets, and means are provided for pivoting the pocket-containing frame about its central longitudinal axis. Preferably, guide plates are associated with the above-mentioned pockets.

Abstract: Disclosed is a tubular device for preventing the egress of gases evolved in an oven chamber during the charging thereof. The tubular device is moved into an operative location forming a hermetic seal with leveling openings in the doors for two adjacent oven chambers, one of which is to receive a coal charge. The gases evolved during the charging operation pass into the adjacent oven chamber where carbonization has proceeded to an advanced state. The tubular device includes two tubular front parts engageable with the leveling openings of coke oven doors, a U-shaped connecting member, and a tubular rear part which is disposed to receive a leveler which can extend through the rear part and into an oven chamber. A flap is raised from a normally-closed position in the rear part of the device by movement of the leveler bar therein. A truck on which the tubular device is mounted can move in a direction of the oven chamber axis on tracks disposed on a frame for the leveler.

Abstract: A coke car is traversed along a battery of coke ovens and receives hot coke discharged through a fall space in an overlying smoke collector hood. The car is moved slowly only a short distance along the battery during the coke pushing operation while it is loaded wih coke at one end of the car and progresses slowly to the other end thereof. Horizontal end sealing plates are fitted to the car and the hood at the level of the top edges of the end walls on each side of the car and hood. The total of the length of the two sealing plates is not less than the distance traveled by the car during coke pushing. Gaps are left between the bottom edges of the side walls of the smoke hood or extension plates disposed thereon and the sealing plates on the coke car. The gaps allow entry of air into the hood for uniform extraction of the emissions formed during the coke pushing operation. In addition, gaps of equal width can also be left between the top edges of the longitudinal walls of the car and hood.

Abstract: A smoke collecting hood traversable on the oven platform along a coke oven battery covers the space in which the pushed coke cake drops into a quenching car while parked in front of the oven chamber. A distributor is suspended from the roof of the hood. The distributor includes metal sheets receding from a central vertical edge facing the oven. The sheets widen outwardly toward the bottom. A linkage is mounted on the distributor at the side remote from the oven to extend through the outer wall of the hood. Outside the hood, a drive is coupled to the linkage to pivot the distributor member about a horizontal axis. The distributor is vertically positioned at the start of the pushing operation so that its vertical front edge cuts through the coke cake and the coke slides down the sides of the distributor into the front and rear parts of the quenching car.

Abstract: A coke side gantry car for a battery of coke ovens supports an extractor and a cleaner for the door, a door frame cleaner, a coke guide grating and a hood for collecting emissions during coke pushing operations. At least one of a plurality of rails to support the gantry car is disposed on the coke platform and another of the rails is disposed outwardly therefrom above and generally parallel with tracks for a hot coke car. A coke guide grating in a casing with continuous side walls moves axially of the oven chamber between the chamber opening and an outward position where a substantial part of the weight is carried by the outer track for the gantry car. The casing extends around the grating and covers the side walls thereof. The casing cooperates with members to form a seal with the coke oven chamber and the smoke hood.

Abstract: A gas-transfer tube assembly is used to extract charging gases through an orifice in the roof of one coke oven chamber and discharge the gases into an adjacent second coke oven chamber through an orifice in the roof thereof. Each orifice has a riser with an annular water seal normally closed by a removable cover. The gas-transfer tube assembly includes downwardly-extending tubular end portions with elbow parts that are selectively connected together by a straight mid-section used to change the spacing between the downwardly-extending end portions. The gas-transfer tube assembly is supported for vertical movement on a car that runs along a monorail supported by buckstays. The car is stabilized by rollers at the top of the car to engage a rail.

Abstract: A coal-charging apparatus includes a charging car with charging bins to discharge coal through filling tubes into charging holes in the roof of an oven chamber. A feed-screw conveys coal from the bottom of a charging bin to a trough communicating with a fixed filling tube. A peripheral trough on the bottom of this tube is filled with sand or liquid and receives a peripheral seal lip on the inside of a movable sealing tube. Hooks on the outside and at the top of the movable sealing tube engage a ring that is suspended by bearings at both ends of a stirrup. The filling tube is raised and lowered by a linkage system that includes a lever supported by a platform and operated by a piston and cylinder assembly. A closure plate is operated by a linkage including a lever supported by a platform and engaged with a piston and cylinder assembly. The closure plate is a leading edge that engages below a wall just above the fixed charging tube.

Abstract: A coke car is moved along a battery of coke ovens to a location for receiving coke from an oven chamber while the car is stationary and for moving to beneath a quenching tower. The coke car includes a generally square box-like container having side walls sealed with a floor that is pivoted about a horizontal axis to bear against seal members. The horizontal axis is spaced from the wall of the car adjacent the coke bench by a distance less than the distance between the axis and the wall of the car adjacent the oven platform. The seal members are disposed on the top of part of the floor which moves away from a side wall during pivotal movement and seal members are disposed on the bottom of a floor part which moves upwardly along a wall of the container during pivotal movement.

Abstract: A carriage movable along the coke side of a coke oven battery and carrying a coke guide, a door extractor, a frame cleaner and a door cleaner. These elements can be manipulated on the carriage so as to effect door extraction, coke pushing, door cleaning and frame cleaning in a minimum amount of time and without the necessity for moving the carriage itself along the coke oven battery while servicing any one coke oven chamber.
