Abstract

Abstract Apparatus for cleaning sealing surfaces of a door assembly for a coke oven has a first header arranged for directing steam onto sealing surfaces at the bottom end of either a door or doorjamb to be cleaned, and a second header arranged for directing steam onto sealing surfaces at the top end of the same door or doorjamb. A third header is mounted on a carriage movable between the first and second headers for directing steam onto sealing surfaces between the top and bottom ends. The cleaning apparatus has a main frame provided with spaced ends, between which extends a guide rail guidingly engaged by the carriage. When specifically intended to be used for cleaning a coke oven door, the first and second headers are pivotally mounted on the main frame; the travel of the third header on the carriage is used to swing the first and second headers in a plane passing between the ends of the main frame when the third header is adjacent the first or second header. Further, this same movement of the third header is used to intermittently actuate valves supplying steam to the first and second headers. When specifically intended to clean a coke oven doorjamb, the first and second headers are mounted on a pair of further carriages also arranged engaging the guide rail and connected to the chain sprocket arrangement. These first and second headers are arranged so that the third header, which is also pivotally mounted on its carriage, and the first and second headers will swing in a plane passing between the ends of the main frame at appropriate times in an operating cycle of the apparatus. Advantageously, the steam used by a cleaning apparatus according to the present invention is dry steam under a pressure of 250 psi.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 241 words
Apparatus for cleaning sealing surfaces of a door assembly for a coke oven, comprising, in combination: a. first header means for cleaning sealing surfaces at a one end of a member to be cleaned; b. second header means for cleaning sealing surfaces at another end of the member to be cleaned; c. a carriage arranged for movement along a path between the first and second header means; d. third header means mounted on the carriage for movement therewith; e. means associated with the first, second, and third header means for swinging the first and second header means about respective pivots arranged perpendicularly to the path of movement of the carriage and parallel to the door assembly whenever the carriage is adjacent the first and second header means; f. a frame having spaced ends, a guide rail mounted on the frame and arranged extending between the ends of the frame, the carriage arranged engaging the guide rail, and means for moving the carriage along the guide rail between the first and second header means, the first, second, and third header means being steam directing headers, the first and second header means being pivotally mounted on the frame adjacent respective ends thereof, and the path of movement of the carriage being a vertical linear path; and g. means actuated by the third header means for intermittently and alternately supplying steam to the first and second header means whenever the carriage is adjacent same.
Claim 2
Dependent Claim 241 words
Apparatus for cleaning sealing surfaces of a door assembly for a coke oven, comprising, in combination: a. first header means for cleaning sealing surfaces at a one end of a member to be cleaned; b. second header means for cleaning sealing surfaces at another end of the member to be cleaned; c. a carriage arranged for movement along a path between the first and second header means; d. third header means mounted on the carriage for movement therewith; e. means associated with the first, second, and third header means for swinging the first and second header means about respective pivots arranged perpendicularly to the path of movement of the carriage and parallel to the door assembly whenever the carriage is adjacent the first and second header means; f. a frame having spaced ends, a guide rail mounted on the frame and arranged extending between the ends of the frame, the carriage arranged engaging the guide rail, and means for moving the carriage along the guide rail between the first and second header means, the first, second, and third header means being steam directing headers, the first and second header means being pivotally mounted on the frame adjacent respective ends thereof, and the path of movement of the carriage being a vertical linear path; and g. means actuated by the third header means for intermittently and alternately supplying steam to the first and second header means whenever the carriage is adjacent same.
Claim 3
Dependent Claim 29 words
A structure as defined in claim 1, wherein the header means all are arranged for directing dry steam under a pressure of approximately 250 psi onto the sealing surfaces.
Claim 4
Dependent Claim 62 words
A structure as defined in claim 1, further including a pair of further carriages engaging the guide rail and connected to the moving means, the first and second header means pivotally mounted on a respective further carriage, and the third header means pivotally mounted on the carriage, all three header means arranged for swinging movement between the spaced ends of the frame.
Claim 5
Dependent Claim 135 words
A structure as defined in claim 1, wherein the frame is arranged with the ends thereof spaced vertically, one end being an upper end and the other end a lower end, with the first and second header means being arranged for swinging about a horizontal pivot, the guide rail is a pair of spaced parallel guide rails cooperatively arranged forming a guide, and the moving means includes a pair of chain sprockets rotatably mounted on the frame adjacent the upper and lower ends thereof, a chain arranged on the sprockets for movement therewith, a pin extending from the chain, a plurality of cam rollers provided on the carriage and arranged engaging the guide rAils, and a slot provided in the carriage and arranged for receiving the chain pin and connecting the carriage to the chain.
