Abstract: A coke oven door fabricated from steel plate including a rectangular main door plate having inner and outer planar door faces. A pair of side support plates are rigidly affixed to the main door plate outer surface to extend longitudinally therealong adjacent the side edges thereof and a pair of end support plates are similarly mounted adjacent the main door plate end edges so as to form a door support frame. A plurality of gusset members are symmetrically disposed generally about the midpoint of the main door plate outer face and extend from one of the side support plates toward the other across the main door plate outer face. A sealing ring is affixed to the main door plate inner surface and adapted to sealingly engage a door frame when the door is placed over the coke oven opening.

Abstract: A new and improved thermal torch or lance and method for boring, cutting, burning and the like of hard base materials which facilitates concentrating and intensifying the thermic reaction thereof. The arrangement includes an elongated hollow inner sleeve or casing generally coextensively received within an elongated hollow outer sleeve or casing with the two casings being dimensioned so that a first gas flow passage is defined therebetween over the cooperative lengths thereof. At least one elongated rod is received within the inner casing in a manner defining at least one second gas flow passage over the cooperative lengths thereof. In operation oxygen is passed under pressure through the first and second passages from the torch inlet end to and outwardly from the torch discharge end. Oxygen passing outwardly from the second passage cooperates in the thermic reaction as is conventional in prior thermal torches.

Abstract: An improved coke oven door frame and jamb assembly wherein the oven front wall which is defined by the frame has an elongated height dimension and the frame and jamb members which comprise the assembly are fabricated from steel plates. The jamb extends outwardly from the outer face of the frame adjacent the peripheral edges thereof outboard of an elongated coke oven door opening included in the frame. The jamb is comprised of a top jamb member, a bottom jamb member and opposed elongated side jamb members which are interconnected to each other at their ends. The frame includes elongated grooves in the outer face thereof adjacent the opposed side edges thereof with these grooves having a width x adapted to receive the side jamb members which have a thickness y. Width x is greater than thickness y in order to provide a clearance area between the groove side walls and the associated side of the jamb members.

Abstract: An improved coke oven leveler door which is constructed from a mild steel plate having substantially flat inner and outer faces with the inner face adapted to selectively close a leveler opening included in the coke oven main door. Support members are rigidly affixed to the outer face of the door and disposed to extend generally radially outward from the central portion of the outer face. Means are also included on the outer face for mounting the door in operative communication with biasing means to place a continuous biasing force against the door at least when it is in a closed position. The inner face of the door includes knife-edge like sealing means protruding outwardly therefrom for sealing the door when it is in a closed position. The configuration of the knife-edge sealing means is such to enhance leveler door sealing during a coking operation.
