Title: Mechanism for the autonomous latching of coke oven chamber doors for horizontal coke oven chambers

Abstract: A device for latching of horizontal coke oven chambers which is triggered by an auxiliary frame located on the coke oven chamber door is provided. The auxiliary frame is restrictively movable in vertical direction on the coke oven chamber door. During the outward movement, the auxiliary frame hits upwardly against limit stop cams firmly mounted on the oven door and transmitting the vertical traction force onto the coke oven chamber door. During the upward movement, the auxiliary frame actuates levers which are rotationally movable to an axis arranged orthogonally to the coke oven chamber and which are connected to a translatorily freely movable latch. On actuation of this lever, it pulls the latch from the latch take-up bearings mounted on the coke oven chamber door so that the coke oven chamber door is unlatched and opened. In an embodiment of the present invention, the coke oven chamber door can be arrested the open or closed position with a device suitable for this purpose.
